Additional information incorporated by reference herein includes: the project application, environmental information questionnaire, environmental review data sheet, project referrals, staff report, General Plan, EIR and Technical Appendices, and other applicable planning documents (i. e. , Petaluma River Access and Enhancement Plan, Petaluma River Watershed Master Drainage Plan, specific plans, etc.) on file at the City of Petaluma Planning Division. Project Name: Pinnacle Ridge Subdivision Site Address: 2762 "P' Street Posting Date: 08/ 21/08 Lead Agency Contact: City of Petaluma Community Development Department Irene T. Borba, Senior Planner I 1 English Street Petaluma, CA 94952 Applicant: Pinnacle Homes Craig Lawson P.O. Box 14189 Santa Rosa, CA 95402 Property Owner: Pinnacle Development Number 21 P.O. Box 14189 Santa Rosa, CA 95402 File No: 05-ZOA-0029-CR APN: 019-401-019 Comments Due: 09/09/08 Phone: (707) 778-4301 Phone: (707) 538-5949 Project Description: The subject property is located at 2762 "P' Street, APN 019-401-019. The subject property consisted of a single-family residence and associated outbuildings all of which have been demolished. In accordance with Resolution No. 2005-198 N.C.S., the applicant obtained approval from the Historic and Cultural Preservation Committee (2/9/06) to demolish the existing residence and all of the outbuildings/accessory structures. The Committee concluded that the structures were not of historical significance and approved the demolition of the existing residence and other accessory structures on the site. The proposed project request is for an 1 I -lot subdivision of single-family residences. The lot sizes are proposed as follows: Lot 1-0.44AC (19,042 SF); Lot 2- 0.43AC (18,695 SF); Lot 3- 0.65AC (28,401 SF); Lot 4- 0.49AC (21,389 SF); Lot 5- 0.44AC (19,074 SF); Lot 6- 0.68AC (gross 29,737 SF, net 29,180 SF); Lot 7- 0.77AC (gross 33,610 SF, net 29,721 SF); Lot 8- 1.56 AC (gross 68,093 SF, net, 66,176 SF); Lot 9- 2.02AC (gross, 87,973 SF, net 86,410 SF); Lot 10- 0.47 AC (20,574 SF) and Lot 11-0.63AC (27,600 SF). The smallest of the lots is Lot 2 at 0.43 AC and the largest lot is Lot 9 at 2.02AC. The average lot size is 0.78 AC (34,014 SF). The total gross lot size is 16.36 acres which includes an Urban Separator Parcel which would consists of 6.32 acres of the site. The Urban Separator Parcel is to the south end of the parcel, adjacent to the city limit line and urban growth boundaries. Page 1 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 2 Potentially Less than I Less Than I No Significant Significant Significant Impact Impact w/Mitigation Impact Measures The proposed project will be accessed by a new public street via "I" Street. All access to the lots will be from the public street and the proposed driveway that extends off the end of the cul-de-sac. No vehicular access to any lot will be allowed from "I" Street. The street width is proposed to be 32' with a 6 -foot planter strip and 5 -foot sidewalks. Lots 6, 7, 8, & 9 will be accessed from a private driveway at the end of the public street. The subject property was annexed to the City of Petaluma in 1989 as part of the Westridge Subdivision Units 4 and 5. An Environmental Impact Report (E.LR.) was prepared for that development. As part of the Westridge Subdivision, the subject property was zoned PUD -Planned Unit District. The proposed project is subject to the 2025 General Plan and the Implementing Zoning Ordinance (IZO). The 2025 General Plan land use designation for the subject property is divided into three separate land use designations; Urban Separator (6.32 acres), Rural Residential (0.1-0.6 hu/ac) (8.15 acres) and Very Low Density Residential (0.6-2.5 hu/ac) (1.89 acres). The proposed request requires approval for a Tentative Subdivision Map for the I1 -lot subdivision. In addition, an Amendment to the Westridge Subdivision Units 4 & 5 PUD -Planned Unit District will be required as noted in Resolution No. 89-10 which approved the unit development plan for the Westridge Units 4 & 5, which included a condition that: "the Remainder of the Hash property (16.5 acres of AP No. 019-401-02) shall be prezoned PUD with the following development/operating standards: a) Existing agricultural operations and uses are consistent with the PUD prezoning designation and may continue at current levels; b) Development Standards shall be consistent with the Petaluma Zoning Ordinance "A" Agricultural District; and c) Any revisions to or increase in the level of development must be the subject of a PUD amendment. Environmental Setting: The subject property is in an area of rural ranches and suburban residential uses. The subject property is located on "I" Street in the southwestern portion of Petaluma, California. The site is in the City of Petaluma and adjacent to the Sonoma County border. Grevilla Drive is north of the subject property and "I" Street borders the property to the east. The site consists of approximately 16.36 acres of land comprised of rolling hills and grassland. The subject property was annexed to the City of Petaluma in 1989 as part of Westridge Units 4 and 5. The property is characterized as having been used for raising livestock. Cross fencing is located at scattered locations on the property and an incised drainage, ranging to about 4 feet deep, is located south of the existing buildings and drains to the northeast. The parcel supports a dense growth of native grasses and several large oak and bay trees at the southern portion of the property. The subject property consisted of an existing single- family residence and associated outbuildings all of which have been demolished. In accordance with Resolution No. 2005-198 N.C.S., the applicant obtained approval from the Historic and Cultural Preservation Committee (2/9/06) to demolish the existing residence and all of the outbuildings/accessory structures. The Committee concluded that the structures were not of historical significance and approved the demolition of the existing residence and the other structures on the site. Responsible/Trustee Agencies: (Discuss other permits, financing or participation required): None.

Name Senior Planner Title Sr aiure Date Page 4 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 5 Evaluation of Environmental Impacts 1) A brief explanation is required for all answers except "No impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question: A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A no impact answer should be explained where it is based in project -specific factors as well as general standards, i.e., the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis. 2) All answers must take account of the whole action involved, including: off-site as well as on-site cumulative, project - level indirect, direct, construction, and operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The lead agency must describe the mitigation measures and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses" may be cross-referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration pursuant to Section 15063(c)(3)(D). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. C) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significant.

Land Use and Planninai. Would the project: a. Physically divide an established community? X b. Conflict with any applicable land use plan, policy or X regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? C. Conflict with any applicable habitat conservation plan or X natural community conservation plan? Discussion: The subject property was annexed to the City of Petaluma in 1989 as part of the Westridge Subdivision Units 4 and 5. An Environmental Impact Report (E.I.R.) was prepared for the development which included the subject property. As part of the Westridge Subdivision, the subject property was zoned PUD -Planned Unit District. The 2025 General Plan land use designation for the subject property is: Urban Separator (6.32 acres), Rural Residential (8.15 acres) and Very Low Density Residential (1.89 acres). The Rural Residential (0.1 to 0.6 hu/ac) land use designation is intended for single-family residential development located primarily at the westem perimeter of the city, along the Urban Growth Boundary. This designation maintains a Waal character and provides a transition to unincorporated rural and agricultural lands. This density range reflects prevailing lot sizes and development patterns. The Very Low Density Residential (0.6-2.5 hu/ac) land use designation is intended for single-family residential development applied primarily to the southern hillsides, with a minimum lot size of half an acre, and larger lots required for sloped sites. The Urban Separator includes open space lands within and/or directly adjacent to the Urban Growth Boundary that are intended to serve as the outer boundary of urban development, as designated by the City of Petaluma. They provide an edge that buffers agricultural fields from urban land, may serve as a recreational area, and act as a key component of the city's open space system. On lands with development potential, the Urban Separator allows transferability of development potential to the remaining portion of the same property. Given the 2025 General Plan land use designations, and the allowance to transfer density from the Urban Separator, the subject property would be allowed to develop 11 units, which is what the applicant has proposed. The project proposal includes an Amendment for the Westridge Subdivision Units 4 & 5 PUD -Planned Unit District. Included in the PUD Amendment are the development standards proposed for the subject property/project. As noted in Resolution No. 89-10 which approved the unit development plan for the Westridge Units 4 & 5, which included a condition that: "the Remainder of the Hash property (16.5 acres of AP No. 019-401- 02) shall be pre -zoned PUD with the following development/operating standards: a) Existing agricultural operations and uses are consistent with the PUD pre -zoning designation and may continue at current levels; b) Development Standards shall be consistent with the Petaluma Zoning Ordinance "A" Agricultural District; and c) Any revisions to or increase in the level of development must be the subject of a PUD amendment. The project site and the proposed project do not conflict with any land use plans or policies. The following 2025 General Plan Land Use Policies are applicable to the project: 1-P-1 Promote a range of land use densities and intensities to serve the community needs within the Urban Growth Boundary (UGB). The subject property has 3 land use designations- Urban Separator (6.32 acres), Rural Residential (8.15 acres) and Very Low Density Residential (1.89 acres) appropriate for the property and the surrounding neighborhoods. 1-P-17 Retain ridgelines and prominent hillsides as open space through appropriate clustering and/or transfer of density to the other parts of a development site (applies to Rural and Very Low Residential areas within the West Hills, South Hills and Petaluma Boulevard North subareas only). Page 6 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 7 Potential I Less Than I Less Than INo Significant Significant Significant Impact impact w/Mitigation Impact Incorporated Goal 1-G-3 Maintain a well-defined boundary at the edge of urban development. 1-P-18 Maintain a permanent open space around the city by the continuation of the urban Separator and the use of an urban Separator Pathway, as designated. The project contains Urban Separator and the applicant has proposed a pathway within the Urban Separator. 1-P-19 Ensure that the Urban Separator function as an overlay, the intent of which is to provide property owners with the opportunity to request transfer of the development potential of land designated as urban separator to another portion of the same site. This is part of the project proposal. The subject property does provide for the Urban Separator (6.32acres) as per the 2025 General Plan. 1-P-20 Maintain a standard width for the urban separator at a minimum of 300 feet except in those areas where it may be variable due to topography, physical or ownership constraints, or is already established at more than 300 feet. The subject property does provide for the Urban Separator (6.32acres) as per the 2025 General Plan and meets the minimum 300 feet requirement. 1-P-21 As development or annexation occurs, the Urban Separator shall be dedicated to the City, at no cost for the City for the land or required interface improvements. The proposed project will be conditioned accordingly. 1-P-23 Establish public scenic or overlook areas in appropriate locations within the Urban Separator concurrently with project design. The project can be conditioned accordingly if apprognate. The project site includes Urban Separator as required in the General Plan and does not affect low-income housing. There is no existing habitat plan or natural community conservation plan that exists for this area of the city. Therefore, no impact to the current land use would occur as a result of the proposal. Mitigation Measures/Monitorine: Not applicable. 2. Population. Emolovment and Housina. Would the project: a. Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? 10 b. Displace substantial numbers of existing housing, X necessitating the construction of replacement housing elsewhere? C. Displace substantial numbers of people necessitating the X construction of replacement housing elsewhere? Discussion: The use in this area is residential. The General Plan and zoning designations for this property is residential and Urban Separator. The proposed project includes the construction of 11 new homes and 6.32 areas of Urban Separator, which therefore would result in a small increase in the population of the area. Mitigation Measures/Monito•ine: Not applicable. 3. Geoloav and Soils. Would the project: a. Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: Page 7 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 8 Potential I Less Than ILo;TI an Nigni£cantSignitSiificant Impact Impact w/Mitigation Impact Incorporated Rupture of a known earthquake fault, as X delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault?

Exposure of people or property to geologic hazards such X as earthquakes, landslides, mudslides, ground fa lure or similar hazards? Discussion: Bauer Associates prepared a report dated March 4, 2004. The geotechnical engineer performed a site visit to observe the surface conditions on December 19, 2003. In December of 2003 the geologist explored the subsurface conditions to the extent of eleven test pits at various locations. The report concluded that from a geotechnical engineering viewpoint, the site can be developed provided that development is designed to mitigate the applicable geologic hazards. The soils overlying the bedrock are weak, expansive, and subject to slow downhill creep. It will be necessary to extend foundation support and fill keyways into bedrock. Foundations must be designed to resist the lateral forces caused by the downhill creep of the soils above the rock Drilled cast -in-place- piers -with_grade-beams are -.typically the most suitable foundation typeconsideringthe soil and bedrock conditions. Spread footings may be more suitable at cut areas that expose non -expansive bedrock. Recommendations to construct critical -use slabs may include slope reconstruction with imported select fill or structurally supporting the slabs on the foundation Page 8 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 9 Potential I Less Than I Less Than INo Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated system Slab on -grade floors may be used in garage and exterior areas provided that slabs are reinforced to resist cracking, separated from foundations and that some cracking and movement is acceptable. Areas of land -sliding are subject to renewed movements. Therefore, developments near landslides will be subject to possible distress. An investigation of land -sliding at the site must be completed (see work done in January, discussed below). Improvements located on slopes should be provided with mitigation to reduce the potential for sloughing of upslope areas to affect the new development. Mitigation may consist of providing a level catchments area, catchments wall, or diversion wall between the improvement and upslope area. Control of surface run-off will significantly enhance the stability of the site. The site must be graded to provide positive drainage away from the building foundations. Roofs must be provided with gutters, and nmoff must be collected and discharged into the site storm drainage system or non -perforated pipes discharging to suitable areas. Sub -drains maybe recommended in selected areas of the development. The report notes that considering the distance to know active faults, the risk of rupture is considered low. They do not anticipate adverse subsurface conditions prone to densification or liquefaction. Severe ground shaking could induce slope failure in weak soils and/or steep slopes, and reactivate areas of old landslides. It will be necessary to design and construct the project in strict accordance with current standards for earthquake -resistance construction. In addition to the above noted report, a more thorough Geotechnical Investigation report dated January 2005 was prepared by Bauer Associates. The scope of work included reviewing selected published geologic information, exploring subsurface conditions at the site, and performing laboratory testing on selected samples. Based on the their work, conclusions and recommendations were developed for: proximity of the site to published active faults, soil/rock and ground water conditions observed, site preparation and grading, foundation type(s) and design criteria, concrete slab -on -grade, retaining walls, pavements, and geotechnical engineering drainage. Field work was performed intermittently between December 19, 2003 and December 20, 2004. The field work consisted of a surface reconnaissance and subsurface exploration. The subsurface exploration included test pits ranging to about 16 feet deep and test borings ranging to about 60 feet deep. The report notes that the property is primarily located on a northwest trending ridge with moderate slope down to "I" Street and that the southwest corner of the property contains slopes down to the west. According to topographic maps, elevations at the property range from about 145 feet at the northern portion of the site to about 330 feet at the south. Slopes ranges within the property are inclined in the range from 2:1 (horizontal to vertical) to 8:1. The report characterizes the property as having been used for raising livestock. The northeast comer of the property was developed with a residence, barn and various outbuildings which have been removed. Cross fencing is located at scattered locations on the property and an incised drainage, ranging to about 4 feet deep, is located south of the existing buildings and drains to the northeast. The report states that the incised drainage may have resulted from surface runoff flows along a previous ranch road and that they did not observe any springs or seepage areas at the site. The parcel supports a dense growth of native grasses and several large oak and bay trees at the southern portion of the property. Bauer Associates note that considering the previous use of the property, they anticipate that such grading was relatively minor and that narrow bands of fill, apparently along the outboard edge of old ranch roads. Geology According to Bauer Associates, the geologic maps indicate that the site is underlain by bedrock of the Franciscan Bedrock Complex, which consists of a mixture of resistant rock types from less than I foot to many miles in length, imbedded in a matrix of pervasively sheared or pulverized rock. The formation of the Franciscan involved extensive thrust faulting that resulted in a melange (mixture) of volcanic, sedimentary, and metamorphic rocks. The report notes a fault extends northwesterly through about the center of the property as indicated on a map by Huffman but that the maps show there is no evidence of this fault as having no Quaternary movement (within about the last 2 million years). The location of the fault was not determined by the geotechnical engineer considering the lack of recent movement and the relatively extensive faulting associated with the Franciscan bedrock unit. There is a map in the geotechnical report that shows the estimated location of the fault. The results of the subsurface exploration indicate that the development areas are primarily underlain be sandstone and shale of the Franciscan. Minor amounts of greenstone, serpentine, and chert were also encountered. The bedrock typically varies from low hardness and friable to soft and plastic. Fracturing of the bedrock frequently ranges from intensely fractures to sheared. Outcrops of sandstone and chert bedrock are exposed at widely scattered locations on the property and neighboring areas. The report notes that many of the bedrock outcrops are typical of melange bedrock terrain where the sheared and clayey bedrock materials tend to weather away and reveal the hard outcrop `knockers'. The bedrock is generally blanketed with colluvial soils ranging to about 4 feet deep. Colluvial soils are accumulations of weathered rock and soil transported downslope by gravity. The colluvium typically consists of medium stiff to stiff sandy clays with variable gravel content. Fills soils were not encountered in the test holes but it appears that isolated portions of the -site may be blanketed -by old fill. -The report estimates that such fill would likely consist of excavated on-site _materials such as variable -density _sandyclay_soils-with -gravels, Page 9 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 10 Potential I Less Than I Less Than I No Significnnt Significant Significant Impact Impact w/Mitigation Impact Incorporated The geotechnical report further goes on to state that the upper portion of the surface soils are often porous and porous soils will be prone to collapse when saturated and under load. The surface soils and portions of the deeply weathered and clayey bedrock have a high expansive potential. Highly expansive materials will experience volume change with seasonal moisture variations. According to the report, such volume changes may crack and heave lightly loaded, shallow foundations, pavements and slabs. Expansive materials subject to volume changes, typically within about 3 feet of sub -grade, will also be more prone to downslope creep movements, even on relatively gentle slopes. The surface soils and old fill are weak and subject to variable lateral or vertical movements. Bauer Associates noted groundwater seepage with several of the test holes but that springs were not observed at the site, and neither were any water tanks or other storage reservoirs. Potential for flooding at the site was not evaluated. Bauer Associates notes that the published map by Smith, T.C., 1986 indicates a large landslide at the eastern portion of the site that extends off-site, across "I" Street. Based on another report prepared by Iv ller Pacific, 2002, stated that the slide appeared to be dormant based on geomorphic evidence. Test pits and borings were taken in this area. The test pits showed large landslide exposed weak soils ranging to about 10 feet deep and often underlain by slickensided clayey landslide planes that are, in -tum, underlain by firm bedrock. The report notes that the bedrock condition appears to be consistent with the bedrock encountered at other areas of the site. Several deep borings were drilled, where possible, and these did not encounter evidence of deeper landslides. The report notes that a couple of the Test Borings 2 and 8, that anomalous drilling conditions (i.e., loss of drilling fluid and clayey bedrock) suggest a zone of more broken or sheared bedrock at a depth of about 18 to 20 feet. The report by Bauer Associates provided a cross-section and notes that it is anticipated it to be related to formational variations and this zone may also represent the limits of deeper landslides. A smaller landslide at the southwest comer of the subdivision indicates that the slide ranges to about 6 feet. Bauer Associates notes an active landslide is located upslope of the southwest property corner, on a neighboring property. It notes that they did not evaluate this feature, it appears that future movements could result in landslide debris at the property comer, generally within the urban separator and that if continued movement occurs, such movements would likely result in debris flowing downslope and off-site, to the northwest (away from the property, west of the Pinnacle Subdivision). Faulting and Seismicity Published geologic maps do not show any active faults at the property. The property is not within a current Alquist-Priolo (AP) Earthquake Fault Zone. The property is approximately 14 miles northeast of the active San Andreas Fault and 6 miles southwest of the active Healdsburg-Rodgers Creek Fault. Older faulting, not considered `active', is located near the site. Bauer and Associates did not observe geomorphic evidence of active faulting and they did not perform subsurface investigative work to evaluate if active faulting crosses the site. Conclusions Bauer Associates states that based upon the results of their work, that they judge that the project is feasible from a geotechnical viewpoint The primary geotechnical considerations for design and construction are: 1) the presence of relatively weak/porous surficial soils and expansive soils that can impose differential movements on shallow foundations, slabs, and pavements; 2) the potential for downslope creep of the colluvial soils overlying the bedrock; and 3) areas of landshding that will be subject to differential movements and slope instability. The report notes that weaklporous surface soils can undergo significant strength loss and settlement when saturated under a load and where evaporation is inhibited by fills, footings, or slabs, eventual saturation of the underlying soils will occur. Bauer Associates note that their experience indicates that variable density old fill soils are also weak and the fills are typically underlain by the weak natural surface soils. Expansive surface soils undergo significant volumetric changes with seasonal variations in moisture content. Such movements can result in unacceptable heaving and cracking of lightly loaded structural elements, such as foundations, pavements, and concrete slabs. Therefore, they concluded that the weak/porous, old fill, and expansive soils are not suitable for support of fills, slopes, roads/pavements or foundations in their present conditions. The report notes that satisfactory foundation supports can be obtained from various foundation systems, such as: 1) drilled, cast -in-place concrete piers and gradebeams, or 2) spread footings, gaining foundation support below the weak soils. Bauer and Associates believes that the pier and gradebeam foundations are the most suitable system considering the depth of the weak sols and expansive potential of the materials. Spread_ footing recommendations were provided for retaining walls in cut areas or where the building area is reconstructed as an engineered fill. Typically, where structures will be located on slopes steeper than about 8:1, or within about 10 - --feet,-the-improvements must be designed to mitigate lateral loads -resulting from soil creep. Baurer and Associates does not Page 10 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 11 Potential I Less Than I I Less Than No Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated recommend slab -on -grade floors in living areas or other critical -use slab areas unless specific things occur. Slab on -grade floors may be used in garages, and exterior areas provided that slabs are reinforced to resist cracking, separated from foundations, and that some cracking and movement is acceptable. The results of the work by Bauer Associates indicate landsliding generally beyond the planned residence locations. The landslide at the southwest corner of the subdivision ranges to about 6 feet deep and appears to be several decades old, but could experience new movement therefore the slide should be reconstructed as engineered fill considering the proximity to the planned improvements. The landslide along 'T' Street appears to be dormant and previous movement is estimated to be several centuries old. The test holes indicate that the landslide is on the order of 10 feet deep. Considering the variable bedrock conditions and mapped fault, it appears that differential erosion may have contributed to the current topographic conditions that would typically suggest deep-seated landsliding. The landslide along 'T' Street is located beyond the limits of the planned development and the slide appears to be dormant, it is recommended that the slide be reconstructed considering potential liability concerns should slide reactivation occur. The slopes in the area are subject to periodic shallow sloughing. Instability can be induced by improper grading, severe earthquake shaking and/or extreme groundwater conditions. The report notes that it may be necessary to provide a catchment wall or level buffer area upslope of structures. Typically this type of mitigation would be recommended where open hillsides are located up-slope of the structures. Buildings with up-slope structures may not require such catchment. The report notes that the catchment can be either constructed adjacent to the structures or incorporated into the structures. Old fills, encountered, should be removed or reconstructed as engineered fill within: 1) building areas; and 2) where located upslope of planned improvements. Subdrains will improve the stability of slopes. The report notes that as with all developments, it will be necessary to carefully control runoff and drainage from improvements. Control of surface run-off will significantly enhance the stability of the site. Roofs must be provided with gutters and downspouts. All lots must be graded to provide positive drainage away from the building foundations and underfloor areas should be sloped to drain and provide with outlets. Recommendations for Site Preparation and Grading Typically, grading should be performed from about mid-April to early October to avoid the risk of encountering seasonally perched groundwater conditions and on-going rainfall. Grading during the dry season will be especially important where landslide repair or other slope stabilization will be performed. Grading during the wet season could result in slope failure(s). Bauer Associates recommends that they be contacted to review the planned grading schedule with the contractor. The site should be cleared of designated brush, rubble and debris and material generated from the clearing should be removed from the site. Existing voids, such as wells, cesspools, abandoned leach fields and septic tank excavations, and other voids generated during clearing should be backfilled in accordance with County Health regulations and as determined by Bauer Associates. Suitable backfill may consist of granular material or compacted soil; capping with concrete may be required. Areas to be stripped of the upper soils containing root growth and organic matter. Bauer Associates anticipates that the required depth of stripping will average about 3 to 6 inches. Deeper striping may be required to remove localized heavy concentrations of root growth. The stripping should be removed from the site, stockpiled for reuse as topsoil, or mixed with at least two parts soil and used as fill in areas 10 feet beyond structures, walks and paved areas. Areas to receive fill, should be prepared by cutting level keyways extending into firm bedrock. Supplemental keyways should be excavated at least 12 inches into firm bedrock at selected intervals. Subsurface drainage facilities should be installed at the rear of keyways as recommended by Bauer and Associates. All exposed soils should be scarified to a depth of 6 inches, moisture conditioned to at least 4% above optimum moisture content, and compacted to at least 90 % relative compaction. The report notes that if isolated deeper zones of soft, saturated, dry, highly porous or organic soils are encountered during excavation and recompaction, the soils should be removed to expose firm soils. On-site soils should be suitable for reuse as general fill provided that: 1) all rock sizes greater than 6 inches in largest dimension and perishable materials are removed, and 2) the fill materials are approved prior to use. Typically, expansive soils should not be used within 3 feet of building pad subgrade and within 3 horizontal feet on the face of fill slopes to mitigate the potential for creep and slope instability. Expansive soils may be suitable for use on fill slopes inclined flatter than about 3:1, and depending on the intended use. Imported fill, as required, should be of inorganic matter and of low expansion potential and should generally conform to a specific requirement as provided in the report by Baurer and Associates. All fill should be placed in thin lifts, moisture conditioned to at least four% above optimum moisture content, and compacted to at least 90% relative compaction. All fills should be continually benched into firm materials, as determined by Baurer and Associates. Building pads should be graded to drain away from foundations and slopes, and should be finished true to line and grade, to present a smooth, f rr , and unyielding subgrade. It may also be necessary -to per formadditionaloverexcavation or provide a greater degree of compaction to reduce the potential for differential- settlement atselected areas, as appropriate. Typically, fill and cut -slopes should either be inclined flatter than 2:1, or Page l I Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 12 Potential Less Than Less Than No Significant Significant Significant Impact impact w/Mitigation Impact Incorporated other mitigation measures should be performed. Fill and cut -slopes should be planted with erosion -resistant vegetation or protected from erosion by other measures upon completion of grading. Ground cover should be maintained on the slopes. Recommendations for Foundations Drilled, cast -in-place, reinforced concrete piers are the recommended foundation type considering the depth of the unsuitable soils and presence of expansive soils. However, spread footings may be more suitable where retaining walls are planned at cut areas or where the weak soils are reconstructed as engineered fill with non -expansive materials. With the exception of spread footings used for retaining wall support, combinations of drilled piers and spread footings should be avoided. Foundations must extend into firm materials, firm bedrock or engineered fill. Recommendations for Drilled Piers and Gradebeams Piers should be at least 14 inches in diameter and extend at least 6 feet into firm materials. In level pad areas cut entirely into bedrock, piers can be 12 inches in diameter. Further, the piers should be at least 8 feet deep and extend into the firm materials at least 1-1/4 times the depth of the overlying soils. The portion of the pier extending into firm materials and 3 feet below lowest adjacent grade, can impose 750 pounds per square feet in skin friction. End bearing should be neglected because of the difficulty of cleaning out small diameter pier holes, and the uncertainty of mobilizing end bearing and skin friction simultaneously. Piers should be interconnected with gradebeams designed to support the design structural loads per current code requirements. Isolated piers should not be used. Piers should be reinforced full length and reinforcing should extend into the grade beams. The gradebeams and piers should be designed and reinforced to resist uplift pressures of 1,500 psf as the expansive soils swell with the increasing moisture content. Pullout capacity of the piers should be considered as one-half the downward capacity. Typically, the piers and gradebeams on, or within about 10 feet of slopes 8:1 or steeper, should be designed and reinforced to resist creep exerting an active equivalent fluid pressure of 55 pounds per cubic foot acting on two pier diameters and the face of foundations. Creep loads will only be applicable to slopes steeper than about 5;1 where non -expansive soils are present. The depth of creep prone soils will be greater of 1) the thickness of weak soils overlying the firm materials; or 2) 3 feet below the finished grade. The actual depth of the creep prone soils will depend on the grading performed and the proximity of the structures to the test holes. The design must be reviewed and revised if the depths of soils exposed during construction are different than used for design. Where up-slope, downslope foundations are spaced wider than 15 feet, tie -beams should be provided to redistribute stresses imposed by the creeping soils. The portion of the piers extending into firm materials may impose a passive pressure of 350 pcf acting on two pier diameters. Passive pressure should be neglected within the upper 12 inches of pad grade unless foundations are confined by other construction. Bauer Associates does not anticipate that caving soils will be encountered. However, if caving soils are encountered, it may be necessary to case the holes. If ground water is encountered, it may be necessary to place the concrete by the tremie method or dewater the holes. Based upon the conditions exposed in the test holes, they do not anticipate hard drilling will be encountered. However, localized hard drilling may be required to achieve the required penetration. The pier holes should contain no more than 3 inches of slough, and the remaining slough should be tamped with a heavy timber prior to concrete placement. Recommendations for Spread footings Spread footings should be at least 12 inches wide and extend at least 12 inches into firm materials. Further, footings should be excavated to at least 30 inches below lowest adjacent grade where expansive materials are exposed. The footings should be stepped as necessary to produce level tops and bottoms, and should be deepened as necessary to provide at least 7 horizontal feet of confinement between the footing bottoms and the face of the nearest slope. Spread footings bearing in firm materials should be designed using allowable bearing pressures 2000 and 3000 psf for dead plus long-term live loads and total design loads, respectively. Footing excavations should be observed prior to the placement of reinforcing steel and concrete. Spread footings on slopes steeper than 8:1 should be designed to resist a creep force equivalent to the depth of weak soils over the firm materials exerting an active equivalent fluid pressure 55 pcf. The depth of the soil will depend on the grading performed and the proximity of the structures to our test pits. The design must be reviewed and revised if the depth of colluvial soils exposed during construction are different than used for design. A minimum creep depth of 3 feet should be used where expansive material is exposed on or near slopes of about 8:1 or steeper. Where retaining walls are constructed, the active lateral earth pressures provided in the following section should be used in lieu of creep pressures. The portion of the foundations extending into firm materials may impose a passive equivalent fluid pressure of 350 pcf and a friction factor of 0.35 times the net vertical dead load. Passive oressures should be neglected within the. upper foot, unless footings are confined by other construction. Recommended Concrete Slabs-OrrGrade Page 12 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 13 Potential I Less Than I Less Than INo Significant Significant Significant Impact Impact w/Mitigation Tmpact Incorporated During foundation installation and utility trench excavation and backfilling, previously compacted sub -grade soils may become disturbed. Where this is the case, these soils should be uniformly moisture conditioned to near optimum moisture content and re - rolled to provide a smooth, unyielding surface compacted to at least 90% relative compaction. Exterior concrete slabs can be placed directly on a properly prepared sub -grade soil. Bauer Associates states that they do not recommend slab -on -grade floors in living areas or other critical -use slab areas unless slabs are: 1) underlain by non -expansive material or at least 30 inches of compacted select fill; 2) structurally supported on the foundations and provided with a void to mitigate uplift pressures. Slab -on - grade floors may be used in garage and exterior areas provided that slabs are reinforced to resist cracking, separated from foundations, and that some cracking and movement is acceptable. Slab -on -grades should be smooth and uniform. Prior to concrete placement, sub -grade soils should be thoroughly moisture conditioned to at lest four percent above optimum. At the less critical slab -on -grade areas, the performance of the slabs can be improved by the placement and compaction of 12 to 30 inches of non -expansive, imported fill materials and/or reworking portions of the weak soils under slabs. Slabs should be underlain with a capillary moisture break and cushion layer consisting of at least four inches of clean, free -draining crushed rock. The crushed rock should be at least 1/4 inch, and no larger than 3/4 inch, in size. An outlet should be provided in the slab rock to avoid water accumulation. Sub -drains under the slab rock, will reduce the risk of seepage through slabs. Moisture will condense on the underside slabs. Where moisture mitigation through slabs is detrimental, an impermeable membrane should be provided between the rock and slabs. Two inches of clean sand can be placed on top of the membrane for puncture protection. Slabs should be at least 4 inches thick and reinforced to reduce cracking. Non -living area slabs should be at least 4 inches thick and reinforced to reduce cracking. Non -living area slabs should be separated from foundations with felt paper, mastic, or other positive and low friction material. If wire mesh is installed it is critical that it is carefully installed. Recommended Catchments & Retaining Walls Foundation support for catchments and retaining walls can be obtained from spread footings or piers in accordance with the previous section of recommendations. Retaining walls free to rotate and with level backfill should be designed to resist an active lateral earth pressure of 40pcf. Where the backfill slopes up steeper than 3:1, the pressures indicated above should be increased to 50 pcf. Rigid walls which can not yield should be designed for an "at -rest' lateral earth pressure of 60 pcf. These pressures do not consider additional loads resulting from adjacent foundations, traffic loads, or other downward loads. Retaining walls should be provided with permanent back -drains to prevent the buildup of hydrostatic pressure. Where migration of water through retaining walls would be detrimental, retaining walls should be waterproofed. Fill materials should be compacted in a manner to prevent over -stressing the wall structures and bracing should be considered. Retaining walls should be backfilled prior to building on or to adjacent the walls. On-site soils may generally be used as backfill however the soils must be in accordance with the recommendations of Bauer Associates. The use of imported granular material will generally require less backfilling effort. Bauer Associates should be contacted to observe backfilling of retaining walls. Foundations and critical -use slabs should not be supported by retaining walls backfill to avoid the potential for differential settlement. Mitigation may include designing foundations and slabs to span from retaining walls to beyond the backfill area. Recommended Pavements Based on Bauer Associates experience with other similar bedrock, they recommend R -Values between 15 and 20. The final pavement section will depend on the sub -grade materials exposed during construction. Bauer Associates should be contacted during site grading to evaluate the materials exposed to determine the most appropriate structural section for use at various areas of the site. Prior to preparation of the sub -grade, all underground utilities in the paved areas should be installed and properly backfilled, and the concrete curbs and gutters or header boards should be in place. Sub -grade soil should be uniformly moisture conditioned to 2% above optimum moisture content and compacted to at least 95% relative compaction, providing a firm and unyielding surface. This may require scarifying and re -compaction to achieve uniformity. The aggregate base materials should be placed in thin lifts in a manner to prevent segregation uniformly moisture conditioned, and compacted to at least 95% relative compaction to provide a smooth, unyielding surface. Recommended Geotechnical Engineering Drainage Ponding water will be detrimental to building foundations and structural elements. The site should be graded to provide positive drainage away from the building foundations and all slopes. Underfloor areas should be sloped to drain and provided with outlets. The downspouts must be collected into non -perforated pipes and discharged: 1) into the site storm drainage; 2) onto concrete slabs-on-gradeor asphalt pavements that drain away- from the foundations; or 3) into erosion resistant areas well away from the structures. Outlets should be provided in the slab rock below critical -use slabs to reduce the risk of water build up in the slab rock.

Keyway sub -drains should be constructed. Additional Recommendations Bauer Associates should be contacted during the final design to provide additional comments and recommendations, as needed. They should review the final plans for conformance with the intent of the recommendations. During grading and foundation construction, they should be provided intermittent geotechnical engineering observations, along with necessary field and laboratory testing, during: 1) removal of weak soil and old fills; 2) fill placement and compaction; 3) preparation and compaction of sub -grade; 4) placement and compaction of Class II Aggregate Base; 5) installation of sub -drains; 6) excavation of foundations; and 7) excavation of cutslopes.

Confect with AB 32and its governing regulations? I I I X Discussion: There maybe some temporary degradation of air quality during the construction phase of this project; however, with the application of the City's standard mitigation measures (e.g., watering graded surfaces to reduce dust, shutting down vehicles when not in use, etc.) theses impacts will be short term and less than significant. The proposed project would not obstruct implementation of the air quality plan for the region. Emissions associated with the project are included as part of the growth projections made for the area. Any associated impacts are expected to be less -than - significant. Development of the project would result in short-term emission of particulates from the site preparation and construction along with a small quantity of pollutants from construction equipment To minimize the local impacts from construction activities, measures for dust suppression and combustion engine emissions control have been incorporated as part of the proposed project. Specifically, project construction would incorporate Basic Control Measures (BCMs) recommended by the BAAQMD as a list of feasible construction emissions and dust control measures that can reduce construction impacts to a less -than -significant level. Implementation of these control measures to be incorporated during construction of the proposed project would reduce related impacts to a less -than -significant level. The proposed project would not create a significant increase in vehicular traffic; therefore, emissions associated with traffic related to the project would be less -than -significant. Due to the scale of the project, it is anticipated that the development would not create a substantial net increase in the cumulative level of any criteria pollutants. Therefore, there would be no significant cumulative impacts. Development of the proposed project would not subject nearby residents to substantial pollution concentrations. The proposed project is residential in nature and is not expected to generate any Hazardous Air Pollutants (HAPs). Development of the project would generate short-term construction emissions. Measures incorporated into the project to control construction emissions would reduce potential air quality impacts from construction to less -than -significant levels. There would be no significant air quality impacts during future operation of the proposed site. There may be relatively minor objectionable odors from the operation of diesel -powered equipment during construction of the proposed new buildings. However, these odors would be short-term and intermittent, and would not result in a significant impact. With the following conditions, the project would not result in a significant impact: 1. The applicant shall incorporate the following Best Management Practices into the construction and improvement plans and clearly indicate these provisions in the specifications. The construction contractor shall incorporate these measures into the required Erosion and Sediment Control Plan to limit fugitive dust and exhaust emissions during construction. a. Grading and construction equipment operated during construction activities shall be properly muffled and maintained to minimize emissions. Equipment shall be turned off when not in use. b. Exposed soils shall be watered periodically during construction, a minimum of twice daily. The frequency of watering shall be increased if wind speeds exceed 15mph. Only purchased city water or reclaimed water shall be used for this purpose. Responsibility for watering shall include weekends and holidays when work is not in progress. C. Construction sites involving earthwork shall provide for a gravel pad area consisting of an impermeable liner and drain rock at the construction entrance to clean mud and debris from construction vehicles prior to entering the public roadways. Street surfaces in the vicinity of the project shall be routinely swept and cleared of mud and dust carried onto the street by construction vehicles. d. During excavation activities, haul trucks used to transport soil shall utilize tarps or other similar covering devices to reduce dust emissions. - Page 16 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 17 Potential I Less Than I Less Than I No ISigmf,na Significant Significant Impact Impact w/Mitigation Impact Incorporated e. Post -construction re -vegetation, repaving or soil stabilization of exposed soils shall be completed in a timely manner according to the approved Erosion and Sediment Control Plan and verified by City inspectors prior to acceptance of improvements or issuance of a certificate of occupancy. f. Applicant shall designate a person with authority to require increased watering to monitor the dust and erosion control program and provide name and phone number to the City of Petaluma prior to issuance of grading permit. 2. All residential units designed with fireplaces shall meet the requirements of Ordinance 1881 N.C.S. for clean -burning fuels. The proposed project does not appear to conflict with AB 32and its governing regulations. Climate change is a shift in the average weather patterns observed on earth, which can be measured by such variables as temperature, wind patterns, storms and precipitation. The temperature on earth is regulated by what is commonly known as the "greenhouse effect." Naturally occurring greenhouse gases in the atmosphere, including carbon dioxide, methane, nitrous oxides, and water vapor, absorb heat from the earth's surface and radiate it back to the surface. Human activities result in emissions of four principal greenhouse gases: carbon dioxide, methane, nitrous oxide, and balocarbons (fluorine, chlorine and bromine). Of all human activities, the burning of fossil fuels is the largest contributor in overall greenhouse gas emissions, releasing carbon dioxide gas into the atmosphere.' The resulting increases in greenhouse gas emissions from human activities are leading to higher concentrations and a change in composition of the atmosphere. For instance, the concentration of CO, in the atmosphere has risen about 30 percent since the late 1800s (National Assessment Synthesis Team [NAST], 2001)' Many sources and models indicate that temperatures on earth are currently warming and will continue to warm at unprecedented levels. The global mean surface temperature has increased by 1.1° F since the 19th century (1PCC Synthesis report, 2001), and the 10 warmest years of the last century all occurred within the last 15 years 2 The many effects of greenhouse gas emissions are still being researched and are not fully known, but are expected to include increased temperatures which would: reduce snowpack, a primary source of drinking water; exacerbate air quality problems and adversely impact human health by increasing heat stress and related deaths; increase the incidence of infectious disease, asthma and respiratory health problems; cause sea levels to rise, threatening urban and natural coastlands; increase pests and pathogens; and cause variations in crop quality and yields. No current CEQA regulation, statute or judicial decision outlines how CEQA analysis of a project's greenhouse gas emissions impact should be performed. Senate Bill 97, adopted in August, 2007, requires the Office of Planning and Research to develop CEQA Guidelines for the mitigation of greenhouse gas emissions or the effects of greenhouse gas emissions by July 1, 2009 which must be certified and adopted by January 1, 2010. It is likely that these prospective Guidelines will provide needed guidance on significance criteria and how to reconcile AB 32, the Global Warming Solutions Act, rollback provisions with CEQA's mandate that CEQA documents are not required to mitigate existing pre -project conditions. As of February 2008, neither the State Air Resources Board nor the Bay Area Air Quality Management District has identified a project -specific significance threshold for analyzing the effects of greenhouse gases. There is a great deal of uncertainty regarding both the regulatory climate and ability to quantify greenhouse gas emissions accurately, as applicable within Petaluma. It is also premature to quantify or rely upon the effects of emission reduction measures that emanate from larger regional, state, federal and global regulatory mandates. In addition, CEQA is only one of many tools being used to approach the greenhouse gas problem, and it is unclear to what extent CEQA documents may rely on other efforts, such as State or Air District measures adopted pursuant to AB 32. 1 Intergovernmental Panel on Climate Change, Fourth Assessment Report (IPCC 4a'), 2007, Working Group (WG) I, Frequently—&sked Questiou2.1; Plow dol-hanan Activities Contribute to Climate Change and Hon, do They Compare with Nahmallniluences? httn://ince-wul.ucar.ediVwel/Renort/AR4WRI Pub FAOs.Ddf Page 17 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page IS Potential Less Than Less Than No Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated Nonetheless, the City is evaluating the contribution of the Pinnacle Ridge project to the cumulative impacts of greenhouse gas emissions in this Initial Study. The evaluation is not quantitative, that is, the tons of CO,e expected to be emitted by 11 dwelling units has not been calculated. Instead, this evaluation focuses on whether or not the project is consistent with the state and local measures and policies regarding greenhouse gases. As described in the EIR on Petaluma's General Plan 2025 — Air Quality: Greenhouse Gas Emissions, Petaluma's contribution to cumulative greenhouse gas emissions constitutes approximately 0.11 percent of California's emissions, and one dwelling unit (1,000 square feet of commercial space) constitutes on average approximately 0.0004 percent (0.002 percent) of Petaluma's future annual emissions. Such contributions to the overall emissions by the City of Petaluma are small and are not easily evaluated or considered on a quantitative basis; therefore, the subsequent evaluation focuses on consistency with measures and policies that are either adopted or proposed, but are intended to reduce greenhouse gas emissions to the extent feasible. Primary sources of greenhouse gas emissions for single family dwellings are from electricity and gas usage, vehicle emissions, and solid waste disposal. The project consists of 11 units on a 16.36 -acre parcel designated with residential and urban separator land use designations. The proposed number of units, density and type of land use is consistent with the General Plan 2025. The Environmental Impact Report (EIR) for the General Plan addresses greenhouse gas emissions based on build -out of the General Plan 2025. This project would not increase emissions over those identified in the EIR. The following table summarizes the State reduction measures, General Plan 2025 policies, and conditions of approval or voluntary commitments made by the project that reduce the project's contribution to greenhouse gas emissions.

California Solar Initiative — 2,000 MW by This measure seeks to deliver 2,000 megawatts of clean, 2016 emission -free energy to the grid through installation of passive solar systems. Pinnacle Ridge is being "pre -plumbed" for both passive solar and solar hot water to allow future owners to install such facilities.

The consistency analysis in Table 1 shows that the Pinnacle Ridge is consistent with the State measures and General Plan 2025 policies regarding greenhouse gas reductions. In addition, it shows that the project applicant has committed to additional greenhouse gas -reduction measures specific to this project. Page 19 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 20 Potential I Less Than I Less Than I No Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated In addition, the applicant has committed to additional greenhouse gas reduction measures and provided staff with a Green Point Checklist for single-family residences specific to the project. The applicants believe that they can achieve a minimum of 89 green points. The plans would have to be reviewed by a Green Rater at time of building permit to ensure that the minimum number of Green Point proposed by the applicant is met. Staff will condition for this appropriately. Based on the small amount of greenhouse gas emissions contributed directly by the project, and based on the consistency of the project with state and local measures and policies, the Pinnacle Ridge is not expected to increase community -wide greenhouse gas levels by a substantial margin compared to pre -project conditions and would not conflict with AB 32 and its governing regulations. Even though the project is consistent with adopted and proposed measures and policies, the City concludes that because of the small size of this individual project, determining its individual contribution to greenhouse gas emissions is too speculative for evaluation, and therefore no determination of significance can be made of the project's net effects relative to GHG emissions (CEQA Guidelines section 15144-15145). Mitigation Measures/Monitoring: Not applicable. 5. Hvdroloav and Water Quality. Would the project: a. Violate any water quality standards or waste discharge requirements? b. Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? C. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river in a manner which would result in substantial erosion or siltation on- or off-site? d. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on -or off-site? e.

Page 23 Less Than( Less Than I No Significant Significant Impact w/Mitigation Impact Incorporated IN ►1 Discussion: The subject property is in an area of Waal ranches and single-family residential uses. The subject property is located on "I" Street in the southwestern portion of Petaluma, California. The site is adjacent to the City of Petaluma and Sonoma County border. Grevilla Drive is north of the subject property and "I" Street borders the property to the east. The site consists of approximately 16.36 acres of land comprised of rolling hills and grassland. The property contained one house and additional accessory structures which have been demolished. The applicant received approval February 9, 2006, from the Historic and Cultural Preservation Committee to demolish the structures. A biological assessment of the subject property was prepared by Darren Wierneyer, staff ecologist for Golden Bear Biostudies (dated August 24, 2004). The report presents the findings of a survey for special status species and sensitive natural communities at the proposed project site. The report describes the site as being approximately 15.56 acres in size and ranges from 140 to 330 feet in elevation. The area surrounding the project site is mostly undeveloped ranchland, with low density single family homes to the east across I Street, and a newer residential subdivision directly adjacent to the north. The report describes the site as that the majority of the site consists of open grassland that has been used as grazing lands up until the recent past. The scope of the report is limited to determining if the project will affect special status habitats (e.g. riparian habitat or wetlands) and\or species. Uninue Characteristics of the Site: The biological assessment describes a seasonal drainage area on the site. This seasonal drainage, which is considered a Section 404 CWA federal jurisdictional wetland, intersects the far southwest corner of the site. Up slope and off site of this seasonal drainage is an unstable slope with evidence of slides and soil movement. A grassy swale originates below the slide. The report states that this drainage becomes moderately eroded on-site, but then returns to a grassy swale before flowing off site to the northwest and that just down slope and off site, the swale becomes more defined and less sloped, and is vegetated with cattails and most likely other wetland species. The report indicates that this seasonal drainage area is located within the proposed urban separator and will not be impacted as part of the site development. The report further goes on to note that within the western portion of the site are two ranch roads, situated in upland grassland habitat. The roads have eroded and now convey surface ran off down slope into a roadside drainage ditch. No wetland vegetation or other wetland indicators were observed within any portion of the eroded roads. The report notes that the roadside drainage ditch, which flows along the eastern boundary of the site, does exhibit riparian vegetation at the northern end in front of the residences. This surface water that flows through this roadside ditch immediately enters an underground storm drain system that apparently flows north to the Petaluma River and therefore, this roadside ditch has no surface connection with jurisdictional wetlands or waterways. The report notes that the preliminary investigation of these features has determined that the eroded roads and the roadside drainage ditch would not be considered jurisdictional by the USACE, the CDFG, or the SFBRWQCB because they are man-made artifacts not connected to existing natural wetlands. The report recommends that each of these agencies conduct site visits to make a final determination on jurisdiction. A letter from USACE on the jurisdictional determination dated 1/06/05 was provided. _The reportnotes that there are several mature trees allocated on the southem portion of the site and that they consists of valley oak (Quercus lobata), California bay (Umbellularia califorica), and coast live oak (Quercus agrifolia). The majority of these trees are Page 23 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 24 Potential I Less Than I Less Than INo Significant Significant Significant Impact Impact w/Mitigation Impact Incomorated situated in the proposed urban separator and will not be impacted. The valley oak is situated within a home lot, but is outside the building envelope, so it appears that it will not be impacted. Filed survevs: Plants Field surveys were conducted on June 28a' and August 2, 2004. They were conducted in a manner to identify any rare or endangered species that may be present during the summer blooming period. Most of the spring annual plants would have bloomed and died months before these surveys, but perennials and late blooming plants would have been identifiable to species. A follow-up study was prepared by Golden Bear Biostudies on Special Status Plant Species Survey, dated July 14, 2005. This report presents the findings of a special status plant species at the proposed subdivision. This report is intended to supplement the Golden Bear Biostudies, Bioloeical Assessment. Special Status Species and Habitat Survev of the Pinnacle Ridee PUD Proiect. Petaluma dated August 24, 2004. The Biological Assessment recommended that special status plant species surveys be conducted in early and mid -spring of 2005 because special status plant species surveys were not conducted in early spring of 2004. No special status plant species were observed at the site during the field surveys conducted by Darren Wiemeyer, Staff Ecologist, on April 20 and May 11, 2005. In addition, no special status plant species were observed during the field surveys conducted on June 28 and August 7, 2004. These four field surveys adequately cover an entire floral season. Based on the results of these surveys, the Pinnacle Ridge PUD project will not disturb or impact any special status plant species. The site lacked appropriate habitats for virtually all of the special status species. The absence of specialized habitats, such as serpentine soils, vernal pools, or salt marshes, greatly restricts the possibility of finding rare and endangered species in the disturbed grazing land. The history of grazing and the spread of exotic, weedy species results in the replacement of the native flora on sites like the project site, as it has throughout California. Based on the results of these surveys, including the surveys conducted in 2004, the Pinnacle Ridge PUD project will not disturb or impact any special status plant species. Animals Field studies were conducted on June 28a and August 2, 2004. Surveys were conducted to determine if habitats supported special status animal species. Protocol level surveys for potentially occurring special status animal species were not conducted as this level of survey does not seem warranted with the absence of critical habitats and being excluded from the range of the California tiger salamander. The determination of presence for animal species possibly occurring was based on habitat assessments, literature review, and queries through CNDDB. Wildlife Research Associates provided the results of a bat habitat assessment and survey in a report dated July 21, 2004. The report describes the results of a recent habitat assessment for bats at the subject property. Development of the property could potentially impact special -status bat species potentially roosting within the buildings and/or trees that occur on the site. Two California Special Species Concern bat species, pallid bat and Townsend's big -eared bat, have potential to occur on the project. In addition, four federal Species of Concern bat species have the potential to occur on the site, roosting either in the available potential building or tree habitat. Several bat species with no special status also occur in the project vicinity. As a result, a habitat assessment of the buildings, and a cursory assessment of the trees around the buildings, was conducted to identify potential roost habitat or observed bat roosting activity. A habitat assessment was conducted on July 14, 2004 by Greg Tatarian. All structures were examined for evidence of bat roosting activity, as shown by openings suitable for entry by bats, accumulations of fecal pellets, urine streaking, or staining or exterior wall and window surfaces. The trees surrounding the structures were evaluated for potential tree roost habitat. Emergence surveys were not conducted as part of this effort. The results showed that none of the structures illustrated past or present evidence of either day or night roosting activity by bats. None of the trees surrounding the buildings appeared to contain cavities suitable for roosting by bats. The oaks on the hill behind the buildings did not appear to contain suitable openings, but because of the density of canopy and undergrowth, it is possible that some cavities exist but were not observed. Wildlife Research Associates provided a letter dated March 16, 2006, regarding results of Predemolition of Roosting bat Surveys, at 2762 I Street, Petaluma, California. This survey is a follow-up to the habitat assessment and survey conducted in July 2004. Oa March 15, 2006 all structures were examined for evidence of bat roosting activity, as shown by openings suitable for entry _bats,accumulations of fecal_pellets,_ urine streaking, or staining or exterior wall and window surfaces. The two trees adjacent to — ht e ma h residence were also surveyed for suitable roost cavities, as well as located on the hill above the horse paddocks. The Page 24 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 25 Potential I Less Than I Less Than I No Significant Significant Significant Impact Impnct w/Mitigation Impact Incorporated results concluded that the physical condition of the buildings on the site remains similar to those observed in 2004, although the structures appear to have decayed further. In accordance with Resolution No. 2005-198 N.C.S., the applicant obtained approval from the Historic and Cultural Preservation Committee (2/9/06) to demolish the existing residence and all of the outbuildings/accessory structures. The structures have been demolished. At the time of the survey in 2004, none of the trees surrounding the buildings appeared to contain cavities suitable for roosting by bats. The cluster on the hill behind the buildings did not contain suitable openings. Although no specific tree roots were observed it is possible that potentially suitable roost cavities occur in the oaks on the hill behind the buildings. If development of the site will occur within 50 feet of the trees, loss of potential tree -roost habitat for several bat species, including colonial, and solitary, obligate tree -roosting bats could occur. Because tree -roosting bats move frequently among roost trees, surveys showing absence from a suitable roost cavity have limited temporal validity. Also, because bats roosting in bark cervices are very hard to detect, results of focused surveys to determine presence or absence of bats from tree roosts should be interpreted cautiously. Other methods to reduce or eliminate impacts (such as seasonal tree removal or trimming, staged removal of limbs and hunk, and removal of adjacent trees not providing habitat prior to those with suitable roost characteristics) should be combined with identification of suitable roost characteristics, which will require a tree survey at a later date. The following recommendations were made: • The oak trees described in this report shall not be removed without fast having a qualified bat biologist conduct emergence surveys during appropriate dates to determine presence or absence of day -roosting bats. No machinery shall be parked or used beneath the trees, to prevent fumes and noise from impacting bats that may be roosting inside tree cavities. • If no bats are observed emerging from cavities in the oaks, the trees shall be removed within 48 hours. If no bats are observed, then tree removal shall occur only between February 15 and April 15, or between August 15 and October 15, in order to avoid impacts to non-volant young or torpid adult bats that may be roosting in cavities in the trees. Wetlands Standard USACE wetland delineation procedures where used to determine whether any wetlands were present on site. A routine on-site investigation was conducted on June 28", 2004. A list of the flora observed on the site during the spring surveys was included in the report in appendix C of the Biological Assessment. The site contains a seasonal drainage, which is considered a Section 404 CWA federal jurisdictional wetland, and intersects the far southwest comer of the site. This seasonal drainage does not possess significant aquatic or stream habitat values. This seasonal drainage did not exhibit any wetiand characteristics or riparian habitat, but it does convey surface run off. Up slope and off site of this drainage is an unstable slope with evidence of slides and soil movement. A grassy Swale originates below the slide area. This swale becomes moderately eroded on-site but then returns to a grassy Swale before flowing off site to the northwest. Just down slope and off site, the swale becomes more defined and less sloped, and is vegetated with cattails and most likely other wetland plant species. This seasonal drainage is located within the proposed urban separator and will not likely be impacted as part of this development. A roadside drainage ditch flows along the eastern boundary of the site and exhibits riparian vegetation throughout the northern portion of the drainage ditch. Riparian vegetation was comprised mostly of non-native species, primarily white poplar, Himalaya berry, and periwinkle. Surface water that flows through this roadside ditch immediately enters an underground storm drain system that apparently flows north to the surface connection with j urisdictional wetlands or waterways. Non-native Grassland This community is the most widespread at the site. There are a few localized areas within the non-native grassland habitat that could be considered oak woodland. One area consists of a clump of coast live oaks (Quercus agrifolia), another area consists of a clump of California bay (Umbellularia califomica), and a third area has a single valley oak tree (Quercus lobata). The report goes on to note that this community occurs across the majority of the site. It forms a dense to sparse cover of annual grasses with flowering clums. It is often associated with numerous species of showy -flowered, native annual forbs (wildflowers). Typical species included perennial ryegrass, slender wild oat, soft chess, Harding grass, sow thistle, and Italian thistle. Most of the other species were weedy annual forbs and grasses. WildlifelSpecialStatus AnimalSpecies Page 25 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 26 Potentia[ I Less Than I Less Than I No Significant Significant Significant I npact Impact w/Mitigation Impact Incorporated The site does not have any native riparian habitat, perennial streams or ponds, or salt marsh habitat. The only special status animals that were observed during filed visits were a female sharp -shinned hawk perched in a eucalyptus tree, a white-tailed kite actively foraging, and evidence of a barn owl roosting in the large bam. The non-native grasses provide foraging habitat for various raptor species (i.e., sharp shinned bawk, red shouldered hawk, redmiled hawk, white -kite, barn owl). No raptor nests were observed during field visits. The project would result in the loss of foraging habitat for several raptor species but would not result in the "take" of raptor species. The seasonal drainage on site lacks perennial flows or pools, does not have any wetland or riparian vegetation, and does not have undercut banks. Therefore, the seasonal drainage does not provide the habitat requirements necessary for California red -legged frog, foothill yellow -legged frog, California freshwater shrimp, western pond turtle, or northwestern pond turtle. Furthermore, it does not have a gravel substrate or any potential spawning habitat on site or upstream to provide habitat for coho salmon or steelhead. The site is outside of the potential range of the California tiger salamander. Tri -colored blackbirds and great blue herons could potentially utilize the wetland habitat downstream and off site of the seasonal drainage, but this habitat will not be impacted. Milkweed and violet were not observed at the site, so it is unlikely that the monarch butterfly, callippe silverspot butterfly, or Myrtle's silverspot would utilize the site. Cream cups and serpentine grasslands were not observed at the site, so it is unlikely that Opler's longhorn moth would utilize the site. The large barn owl site has been and appears to continue to provide roosting habitat for one or more barn owls. White wash and regurgitated owl pellets provide evidence of recent barn owl activity in the large barn. There was no evidence of small rodents utilizing the site, but there were no ground squirrel burrows or other large burrows on site that could provide habitat for burrowing owls. There was no evidence of American badger or burrowing owls utilizing the site. A bat habitat and survey conducted at the site determined that none of the structures on site showed evidence of past or present use by bats, but the structures all provide elements that bats find suitable for day and/or night roosting activity. Results of the bat surveys were discussed above in the Animal Section. Special Status Plants No special status plants were observed during the field surveys. The report notes that the site lacks appropriate habitats for virtually all of the special status species. The absence of specialized habitats, such as serpentine soils, veinal pools, or salt marshes, greatly restricts the possibility of finding rare and endangered species in the disturbed grazing land. The history of grazing and the spread of exotic, weedy species results in the replacement of the native flora on sites like the project site, as it has throughout California. Due to the time of year, it was not possible to state with absolute certainty that early spring -blooming special status plants were not present. Although these species are not likely special status plant surveys were conducted in early and mid -spring of 2005. A large valley oak tree is situated within a home lot, but is outside of the building envelope, so it appears it will not be impacted. Provisions should be made to avoid damage to its roots and drip line, and to prevent increased soil moisture around the tress from landscape irrigation. A follow-up report was provided by Golden Bear Associates dated July 14, 2005. The intent was to supplement the Golden Bear Biostudies Bioloeical Assessment Special Status Soecies and Habitat Survev of the Pinnacle Ridee PUD ProiecL Petaluma. Results of this field investigation were discussed above under the Plant Section. Special Status Habitats Special status habitats in the form of a seasonal drainage occurs on site. The seasonal drainage, which is considered a Section 404 CWA federal jurisdiction wetland, intersects far southwest comer of the site. This seasonal drainage does not possess significant aquatic or stream habitat values. This seasonal drainage did not exhibit any wetland characteristics or riparian habitat, but it does convey surface runoff. Up slope and off site of this drainage is an unstable slope with evidence of slides and soil movement. A grassy swale originates below the slide area. This swale becomes moderately eroded on-site, but then returns to a grassy swale before flowing off site to the northwest. Just down slope and off site, the swale becomes more defined and less sloped, and is vegetated with cattails and most likely other wetland plant species. This seasonal drainage is located within the proposed urban separator and will not be impacted as part of this proposed development.

It is recommended that the USACE, CDFG, and SFBRWQCB conduct site visits to make a final determination on jurisdiction. If any of these agencies exerts jurisdiction over the roadside drainage ditch, then a permit would be required though that agency for impacts to the roadside drainage ditch. In addition, habitat mitigation may be required for the loss of this habitat. Mitigation 2.1 request site visits by the USACE, CDFG, and SFBRWQCB to make final determination regarding jurisdiction of the roadside drainage ditch. Mitigation 2.2 if determined jurisdictional, obtain permits through the appropriate agencies CUSACE, CDFG, and/or SFBRWQCB) for the impacts to the roadside drainage ditch. Mitigation 2.3 If determined jurisdictional, then mitigation for the loss of habitat in the roadside drainage ditch will be required through the appropriate agencies (USACE, CDFG, and/or SFBRWQCB). The determination has been made by USACE, that this roadside ditch is not jurisdictional wetlands. M ligation 2.4 Conduct construction activities during summer months when the roadside drainage ditch is dry to prevent impacts to water quality. A letter has been received from USACE determining that the roadside drainage ditch is not jurisdictional. Potential Impact 3 Construction activities may result in erosion and sedimentation of downstream aquatic habitats. Sediment transport from construction activities to the roadside drainage ditch and downstream aquatic habitats can have deleterious effects on aquatic organisms in these aquatic habitats and result in violations of State and Federal water quality regulations. Mitigation 3.1 Ensure that best management practices are adopted in order to minimize the amount of sediment leaving the site during construction activities. Mitigation 3.2 Obtain a general permit for Strom Water Discharges from Construction Activities through the SFBRWQCB. Mitigation 3.3 Prepare and implement a Storm Water Pollution Prevention Plan for construction activities. Potential Impact 4 Construction and landscaping activities may result in impacts to valley oak tree. Construction and landscaping activities at Lot 8 should avoid impacts to the valley oak tree. Mitigation 4.1 Install protective fencing around the valley oak tree prior to construction activities. Fencing should encompass the entire canopy of the tree to prevent impacts to its roots and drip line. Mitigation 4.2 Landscaping and irrigation should be designed to not impact the roots and drip line of the valley oak tree. The report notes that the impacts would be less than significant by implementing the above noted mitigation measures and complying with agency conditions. A Tree Preservation & Mitigation Report was prepared for the subject property. The report was prepared by John Meserve of Horticultural Associates and dated August 13, 2004. Five trees were evaluated based on their trunk diameter and location in relation to the proposed project construction. Each of the trees was evaluated for size, health and structural condition. The report also provided an estimate of the development impact on each tree, as well as specific recommendations for preservation or removal. _t.

Tree #4 Quercus lobata (valley oak) Tree vigor is good; trunk exhibits significant decay; root collar appears to have extensive decay' canopy structure is generally symmetrical; habit is dense; canopy is low branched; watersprouts present; no significant pest present Minimal impact to the tree will occur. This tree is off-site overhangs the rear area of the proposed Lot 8. While it has some structural deficiencies it appears to be a preservable tree. Tree #5 Umbelhdaria califontica (California bay): Tree vigor is good; trunk exhibits minor decay; root collar appears to have extensive decay; canopy structure is generally symmetrical; habit is dense; canopy is low branched; structurally weak; co -dominant leaders present; no significant pest present There is no impact to this tree due to development. The tree is structurally unstable due to significant decay in the root crown area. It poses no hazard because it is being preserved in an urban separator area where no targets are expected to be present Remove if a falling tree is a concern. Preserve and allow failing naturally over time. With the following mitigation measures the potential impacts would be less than significant: Mitieation Measures/Monitorine; No trees or limbs of the oak trees described in the Wildlife Research Associates report shall be removed without fust having a qualified bat biologist conduct emergence surveys to determine presence or absence of day roosting bats. No machinery shall be parked or used beneath the trees, to prevent fumes and noise from impacting bats that may be roosting inside tree cavities. If no bats are observed emerging from cavities in the oaks, the trees shall be removed within 48 hours. If no bats are observed, then tree removal shall occur only between February 15 and April 15, or between August 15 and October 15, in order to avoid impacts to non-volant young or torpid adult bats that may be roosting in cavities in the trees. 2. Conduct construction activities during summer months when the roadside drainage ditch is dry to prevent impacts to water quality. 3. Construction activities may result in erosion and sedimentation of downstream aquatic habitats. Sediment transport from construction activities to the roadside drainage ditch and downstream aquatic habitats can have deleterious effects on aquatic organisms in these aquatic habitats and result in violations of State and Federal water quality regulations. -4. —Ensure thatbestmanagement practices are adopted in order to minimize the amount of sediment leaving the site during construction activities.

Prior to issuance of development permits, obtain a general permit for Strom Water Discharges from Construction Activities through the SFBRWQCB. 6. Prior to issuance of development permits, prepare and implement a Storm Water Pollution Prevention Plan for construction activities. 7. Construction and landscaping activities may result in impacts to valley oak tree. Construction and landscaping activities at Lot 8 should avoid impacts to the valley oak tree. Prior to issuance of development permits, protective fencing shall be installed. Fencing should encompass the entire canopy of the tree to prevent impacts to its roots and drip line. 8. Landscaping and irrigation should be designed to not impact the roots and drip line of the valley oak tree. Noise. Would the project result in a. Exposure of persons to or generation of noise levels in X excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b. Exposure of persons to or generation of excessive X groundborne vibration or groundbome noise levels? C. A substantial permanent increase in ambient noise levels X in the project vicinity above levels existing without the project? d. A substantial temporary or periodic increase in ambient X noise levels in the project vicinity above levels existing without the project? e. For a project located within an airport land use plan or, X where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? f For a project within the vicinity of a private airstrip X would the project expose people residing or working in the project area to excessive noise levels? Discussion: Temporary increase in noise levels would occur during construction due to the use of heavy construction equipment. However, this noise would be short-term and temporary. An increase in noise will result from the conversion of the previous ranch use with one single-family residence, (which the ranch use has not occurred on this site for a number of years and the residence has been vacant for sometime) to 11 single-family residences. The increase in noise would be attributable to typical noises generated from activities with any residential area. No significant environmental impacts will occur as a result of this proposal. Mitieation Measures/Monitorine: Not applicable. 8. Visual Quality and Aesthetics. Would the project: - a. - have a substantial adverse effect on a scenic vista?

Less ThanLess Than Significant Significant w/Mitigation Impact Incorporated X 14 Page 30 No Impact Discussion: The 16.32 -acre site contained one house, and other detached accessory structures. The applicant did obtained approval from the Historic and Cultural Preservation Committee (2/9/06) to demolish those structures per Resolution No. 2005- 198 N.C.S. Those structures have since been demolished. The subject property is in an area of rural ranches and suburban residential uses (north). The subject property is located on "I" Street in the southwestern portion of Petaluma, California. The site is adjacent to the City of Petaluma and Sonoma County border. Grevilla Drive is north of the subject property and "r' Street borders the property to the east. The site consists of approximately 16.32 acres of land comprised of rolling hills and grassland. Development of the 16.32 acre site will provide for i l -single-family residences, and other site improvements. Outdoor lights in conjunction with the development shall include measures to reduce light impacts i.e., low intensity lights only (no flood lights). Low profile light standards and\or wall mounted lights, lights attached to the buildings shall provide a "soft wash" of light against the wall, no direct glare, no pole mounted lights, etc the lights will contribute cumulatively to the existing nighttime glare. All lighting, as well as site plan, architecture and landscaping will be subject to the review and approval of the Site Plan and Architectural Review Committee (SPARC). Approximately 6.32 acres of the site will be set aside as Urban Separator and dedicated to the City. Urban Separator includes open space lands within and/or directly adjacent to the Urban Growth Boundary that are intended to serve as the outer boundary of urban development, as designated by the City of Petaluma. They provide an edge that buffers agricultural fields from urban land, may serve as a recreational area, and act as a key component of the city's open space system. Per the proposal, the proposed 6.32 acres for the Urban Separator will be dedicated to the City. It is anticipated that no significant impacts will occur as a result of the project proposal. Mitieation Measures/Monitorine: 1. All exterior lighting shall be directed onto the project site and access ways and shielded to prevent glare and intrusion onto adjacent residential properties and natural/undeveloped areas. Plans submitted for SPARC review and approval shall incorporate lighting plans, which reflect the location and design of all proposed streetlights, and any other exterior lighting proposed. 2. Development plans shall be designed to avoid vehicular lighting impacts to bedroom areas and other light-sensitive living areas of any nearby residential lot, home or facility. Development plans for lots proposed at street intersections or in other potentially light-sensitive locations shall incorporate architectural or landscape design features to screen interior living space from headlight glare. 3. No illumination shall be installed within the designated open space area except for low-level lighting along designated pathways adjacent to public streets. The improvement and landscape plans prepared for the project shall reflect the location and design details of all light fixtures proposed. Said locations and details shall be reviewed and approved by the Site Plan and Architectural Review Committee prior to issuance of development permits. 4. -Shade trees shall be incorporated into building and improvement plans along public streets and within parking areas in conformance with the City's Site Plan and Architectural Review Guidelines to reduce glare and to provide shade.

All new and existing overhead utilities (except for high voltage transmission lines) shall be placed underground. 6. Architectural details, landscape plans and specifications, and detailed site plans shall be subject to review and approval by the Site Plan and Architectural Review Committee prior to issuance of development permits. 9. Hazards & Hazardous Materials. Would the project: a. Create a significant hazard to the public or the X environment through the routine transport use, or disposal of hazardous materials? b. Create a significant hazard to the public or the X environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? C. Emit hazardous emissions or handle hazardous or acutely X hazardous materials, substances, or waste within one- quarter mile of an existing or proposed school? d. Be located on a site which is included on a list of X hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e. For a project located within an airport land use plan or, X where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f For a project within the vicinity of a private airstrip, X would the project result in a safety hazard for people residing or working in the project area? g. Impair implementation of or physically interfere with an X adopted emergency response plan or emergency evacuationplan? It. Expose people or structures to a significant risk of loss, X injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Discussion: The proposed project will not create a risk of an explosion or the release of hazardous substances including, but not limited to oil, pesticides, smoky chemicals or radiation, in the event of an accident. The project will not interfere with emergency evacuation plans, create potential health hazards, or result in an increase in hazards due to flammable brush, grass or trees. No storage of chemical or hazardous materials is anticipated with the uses at this site. Except during construction where equipment may be used requiring various types of fuel, the project does not involve hazardous substances and should have no effect on emergency evacuation plans. Page 31 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 32 Potentinl Less Than Less Than No Significant Significant Significant Impact Impact w/Midgation Impact Incomorated Trans Tech Consultants MC) conducted a Phase I Environmental Site Assessment (ESA) for the proposed project, dated June 2004 (Job No. 1605.01). The ESA was prepared to evaluate the potential impact from hazardous materials at the site and other properties in the vicinity. The ESA included the following: • Review of available documents pertaining to the subject property, including a 50 -year chain -of —title report, and topographic maps related to the development and current physical nature of the subject property. • Review of an environmental database report which lists sites, including the subject property and adjacent properties, within a 1 -mile radius that have been included on Federal, State, or Local agency lists such as the National Priorities List (NPL), Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS), Resource Conservation and Recovery Information System (RCRIS) Sites, registered and leaking underground storage tanks (USTs), and emergency response notifications (ERNS). • Conducting a site visit to evaluate property use and inspect for visible evidence of the generation, use, storage, or disposal of hazardous materials. • Interviewing known available parties knowledgeable about the subject property to research site uses and any past or current onsite hazardous materials usage, storage, or disposal. • Summarizing the results of the findings of the assessment. Underground Storage Tanks: TTC conducted a Site reconnaissance of the subject property in May and June of 2004. Observations made during the site reconnaissance did not reveal any evidence indicating the presence of underground storage tanks (USTs)) and historical information did not indicate evidence to suggest that USTs have been located at this site in the past. Above Ground Storage Tanks: No aboveground storage tanks (ASTs) were observed during the site reconnaissance. Based on the information received from neighbors, an aboveground fuel tank was located on-site, east of the former water tank house. The AST was used to fuel as many as ten ice cream trucks which the previous property owner Mr. Hash owned and operated. Neighbors indicated that the ice cream business operated in the 1970's. There was no pump island associated with the AST and the assumption is that it was gravity fed. During the Site reconnaissance the area where the former AST was located was carefully examined for visual or olfactory evidence of fuel spillage. No staining or smell was discernible. City of Petaluma files contain no reference to the AST. Other Observations: The site appears to have been unused for sometime. The bushes along "I" Street are very overgrown and the outbuildings are in various stages of disrepair. There was no evidence of storage or manufacture of hazardous materials. The house was heated by a fireplace, no ponds, pits, sumps or other water bodies were observed, the site is connected to City of Petaluma sewer and water, and no distressed vegetation was observed, nor where there any noxious odors. Adjacent Properties: Based on the site reconnaissance and interviews with neighbors, and a review of historical records and historical topographical maps, the vicinity has been primarily working ranches since at least the early 1900's. In 1990 the former property owner's the Hash's sold the eastern 3 acres of the ranch to Condiotti Enterprises. These 3 acres were subsequently built with single-family residences which remain adjacent to the subject property. Other adjacent properties include working ranches with horse and cattle, and residences which were built in the 1950's. There was no evidence of the manufacturing or storage of hazardous materials observed at adjacent properties. Historic Topographic and Aerial Map Review: Historical topographical maps of the site and vicinity were reviewed from 1912, 1954, 1968, 1973 and 1980. The 1912 map shows four buildings in the vicinity of the site. The 1954 map shows the current residences in the vicinity and the 1968 map shows the residence and an outbuilding. The 1973 and 1980 maps are shown as the same residence and outbuilding. Aerial photographs from 1965 and 1993 were reviewed. The 1965 photograph shows the residence and one out building. The 1993 photograph sows the site in its current configuration with the residence and the outbuildings, as well as the newer residences along Grevilla Drive. All of the photographs indicate that the area has remained rural and relatively unused. Regulatory Agency Lists and Records Review: Page 32 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 33 Potential Less Than Less Than No Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated An Environmental Data Resources, Inc (EDR) environmental database report was obtained and reviewed for the subject property. The EDR report fists properties within the minimum search area listed that were included in any of the regulatory agency databases. The locations of these sites are shown on the maps that are part of the EDR report. The results are as follows: EDR researched federal, State and local regulatory agency databases to meet ASTM Standard requirements within a one - mile radius of the site. Sites which are within a one-quarter mile radius of the subject property are discussed below. Sites which are listed for permits only or have a regulatory "No Further Action" status are not discussed. Sites which are located at a distance greater than one-quarter mile from the subject property were not deemed to pose a threat of adverse environmental impact to the subject property and are listed in the ADR report. One site was identified within a one-quarter mile radius of the subject property. The Bostrom Property, located at 479 Deer Creek Lane, was reported as having had a leaking underground fuel storage tank The site was investigated under the oversight of the San Francisco Bay regional Water Quality Control Board and was given a Case Closed -no further Action status. Fire personnel indicated there are no records of hazardous materials spills or responses or environmental concerns related to the subject property. San Francisco Regional Water Quality Control Board indicated that there were no records on file for the subject property. Sonoma County Department of Emergency Services indicated that there are no records on file for the subject property and Sonoma County Department of Environmental Health and Sonoma County Permit and resource Management also indicated there were no files on record for the subject property. Findings: Based upon available information, this assessment has revealed no evidence of recognized adverse environmental conditions in connection with the subject property. It appears that the subject property has historically been a working ranch with horse and cattle. Anecdotal information from the neighbors did not indicate any knowledge of hazardous materials usage at the site. Nearby properties have been ranches, with residential development beginning in the 1950's along "I" Street to the southeast and subdivision to the east of the site in the early 1990's. Conclusions: Agricultural chemicals or other hazardous materials may have been used on the subject property and nearby properties. However, no known spills, storage or intensive use of agricultural chemicals is documented. Therefore, the study concluded that the environmental risk from agricultural chemical use to be minimal. Mitieation Measures/Monitorine: Not applicable. 10. Transoortallon/Traffic. Would the project: a. Cause an increase in traffic which is substantial in X relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? b. Exceed, either individually or cumulatively, a level of X service standard established by the county congestion management agency for designated roads or highways? C. Result in a change in air traffic patterns, including either X an increase in traffic levels or a change in location that results in substantial safety risks? d. Substantially increase hazards due to a design feature X (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Page 33 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Pole Signifialcant Impact C. Result in inadequate emergency access? f. Result in inadequate parking capacity? g. Conflict with adopted policies, plans or programs supporting alternative transportation, i.e., bus turnouts, bicycle racks)? Page 34 Less Than Less Than No Significant Significant Impact w/Mitigation Impact Incorporated FA X VA Discussion: The project will not result in a significant increase of vehicles to the site. There may be some short-term impacts to automobile, bicycle and pedestrian traffic due to construction vehicles entering and exiting the project site. Construction vehicles will be contained within the site and will not impact the movement of local traffic. The project has been reviewed by the Fire Marshal to ensure that the project provides adequate access for emergency vehicles. Therefore, no significant environmental will occur as a result of this proposal. A Traffic Impact Analysis for the proposed project was prepared by Allan Tilton of W -Trans, dated June 6, 2005. The analysis evaluated potential traffic impacts that would be expected from the proposed subdivision of the 11 single-family residences and addresses the potential impacts the project may have on surrounding streets in the area. Existing Conditions: The study area consisted of 'T' Street adjacent to the project site. "I" Street has two lanes with sidewalk, curb and gutter on the northerly side of the street. Currently "I" Street carries approximately 3,000 vehicles per day. The General Plan adopted Level of service (LOS) standard for streets indicate the minimum acceptable operation is LOS C where it is currently LOS C or better. Where operation was at LOS D or E in 1985, it shall not deteriorate to the next lower level. Under a City Council Policy adopted in 1990, mitigation is required at any study intersection where the project results in delay worse than LOS D. Currently, the portion of "I" Street adjacent to the project site operates at LOS A during the p.m. peak hour. Project Trip Generation and Distribution: Project trip generation and distribution was calculated for this project under the Single -Family Detached housing category (Land Use #210) to project vehicle trips. Per the traffic analysis, the proposed Pinnacle Ridge Subdivision is expected to generate an average of 105 daily trips, including 8 trips during the a.m. peak hour, and 11 during the p.m. peak hour. Trip distribution characteristics were determined by examining existing patterns of traffic and the locations of services and schools in the project area. It was assumed that approximately 90% of the traffic originating from the proposed subdivision would be oriented to the north on "D" Street, with the retraining 10% oriented to the east on Sunnyslope. Existing Plus project Conditions: Upon the addition of project -generated traffic, "I" Street is expected to continue operating acceptably at LOS A during p.m_ peak hour with a volume -to -capacity ratio increase to 0.17 from 0.16, an increase of 0.01. The project will have a minor incremental impact with service levels remaining at LOS A. Site Access: Access to the project would be provided via new street connection to "I" Street. It is expected that the proposed street connection would provide adequate access to the surrounding street network. Future Conditions: The City of Petaluma has developed a Traffic Model for use in evaluating the potential traffic impacts of build -out of the land uses described in the current General Plan together with new or improved streets. The Pinnacle Ridge Subdivision site is located within TAZ 117 of the City's Traffic Model. The General Plan assumptions for TAZ 117 include an additional 11 single-family homes from year 2002 baseline conditions. The Pinnacle Ridge Subdivision at 11 single-family homes will meet the anticipated development potential of TAZ 117 and the trips from this project have been considered within the General Plan Update. Conclusions: The project will add an average of 105 daily trips to the area circulation system, including 8 a.m. peak hour trips and 11 p.m peak hour trips, Page 34 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 35 Potential Less 11ian Less Than No Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated • The service level on "F' Street will remain at LOS A with project added traffic volumes, • The added traffic volumes have been foreseen and are included in the City of Petaluma General Plan Traffic Model and • The project access design will need to maintain a minimum of 395 feet of sight distance in both directions along "F' Street. The final improvement plans will need to incorporate landscaping and site grading that will maintain the required sight distance. Mitigation Measures/Monitoring: Not applicable. 11. Public Services. a. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Fire protection? I X Police protection? X Schools? ( X Parks? I X Other public facilities? I X Discussion: The proposed project entails the development of 11 new single-family residences. Additional fire and police service calls as well as road maintenance may occur as a result of this proposal. However, the impact upon schools, parks or other governmental services will be minimal as a result of this proposal. The applicants will be required to pay the applicable development fees that are assigned to all other proposals to address the incremental impact that the proposal presents to all public services. Therefore, no significant environmental impacts will occur as a result of this proposal. Mitigation Measures/Monitoring: Not applicable. 12. Recreation. a. Would the project increase the use of existing X neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b. Does the project include recreational facilities or require X the construction or expansion on recreational facilities which might have an adverse physical effect on the environment? Discussion: Development of the area will result in a slight increase in residents to the area, which would indirectly increase demand for recreation facilities in the area. The proposal does provide for approximately 6.32 acres for Urban Separator. Urban Separator includes open space lands within and/or directly adjacent to the Urban Growth Boundary that are intended to serve as the enter -boundary of urban development, as designated by the City of Petaluma. They provide an edge that buffers Page 35 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 36 Potential I Less Than I Less Than INo Significant Significant Significant Impact Impact w/Mitigation Impact Incomomted agricultural fields from urban land, may serve as a recreational area, and act as a key component of the city's open space system. Per the proposal, the proposed 6.32 acres for the Urban Separator will be dedicated to the City. Mitigation Measures/Monitoring: Not applicable. 13. Utilities Infrastructure. Would the project: a. Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b. Require or result in the construction of a new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? C. Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? d. Have sufficient water supplies available to serve the project from existing entitlements needed? e. Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? g. Comply with federal, state, and local statutes and regulations related to solid waste? X X V4 X M X �01 Discussion: The proposal will have an incremental effect upon existing utility services. New extensions of service lines will be required to provide water, sewer, natural gas, electric, and storm drain utilities to the new structures. This extension is consistent with the expected service needs of the 2025 General Plan. The proposal will require the extension of utilities and services to the new buildings. For these reasons, it is expected that no significant impacts to the utility infrastructure will occur as a result of this proposal. Water System Distribution Calculations were prepared by Lafranchi and Associates, date stamped by the City of Petaluma August 18, 2005. The report notes that the project is located in a pressure deficient area. The report notes that air gap pumping systems will be required by the City for all residents. The sizing of the air gap systems next to each proposed residence will be done during the improvement plan design. The City system pumping information was provided by Curt Bates of the Public Works Department Based on the information provided the system pump curve was designed. An appendix of this document provides static and residual pressures using the existing City water system pressure for the proposed subdivision at the water meter and at the residence. The following was found: e Static pressures: Static pressures before the water meter ranged from 15 to 43 psi. Static pressures at the residences ranged from -5 to 43 psi and that they will design using a Class 150 piping for the project. e Residual Pressures: Residual pressures before the water meter ranged from 15-42psi. Pressures at the residences ranged from -17psi to 31 psi. This will result in the requirement of the air gap systems immediately following the water meter since the pressures were negative. Since the residual pressure at each residence is less than 50 psi, an air gap system will -------be required for every lot. Page 36 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 37 Potential Less Than Less Th¢n No Significant Significant Significant Impact Impact wlMitigation Impact Incorporated • Pipe size: the water main will be 12 inches and the laterals will be 2" with I" meters. • Design methodology: Hand calculations were provided in one of the appendixes of the document that provided a rough estimate of maximum and minimum pressures throughout the site. A more detailed analysis was done using the following methodology: Static Pressure -The static pressure for each node was determined by reducing the pressure from the City connection to the node by the change in elevation. Residual Pressures- The residual pressure for each node was determined by reducing the static pressures by the pipe head loss. The velocity component of the Bemoilli equation was ignored since the velocities associated with the domestic water use is around 0.31 fps. The determination of pipe loss was obtained from the Goulds Pumping guide which compiles the losses per 100 feet of pipe PVC piping. The determination of equivalent lengths for bends, tees, etc., was obtained using a table formulated by Goulds Pumping guide that was included in one of the appendixes of the report. Fire Water- One for the appendixes provided static and residual pressures at each fire hydrant using the existing City water system pressure for the proposed subdivision. The following summarizes their findings: • Static Pressures: static pressures at the fire hydrant ranged from -3 to 42 psi. Class 150 piping will be sufficient for the proposed project. • Residual pressures -1500 GPM: Residual pressures at the fire hydrant ranged from -11 to 36 psi so a fire pump will be required. Specifically, FH #4 and 5 will require a fire pumping system in order to meet the City requirements of flow and pressure. • Pipe Size and Equipment: The water main must be a minimum of 12 inches. An 8" DDCV (Double Detector Check Valve) will be installed before the fire pump house. • Design methodology: Hand calculations were provided in one of the appendixes that provided a rough estimate of maximum and minimum pressures throughout the site. A more detailed analysis is provided in an additional appendix of the document using the following methodology: • Static pressure: Time static pressure for each node was determined by reducing the pressure from the City to connection to the node by the change in elevation. • Residual pressures: The residual pressure for each node was determined by reducing the static pressures by the pipe bead loss. The velocity component of the Bemoilli equation was not ignored since the velocities associated with the domestic water use is around 0.17 fps. The Bemoilli equation was used in determining the pipe head loss. • Fire Sprinkler system: For the fire sprinkler system, the report states that they are assuming that they will need 60 GPM to be available for each home and that the air gap systems on each home will boost the pressures to a minimum of 50 psi.. Time following findings were made: • Static pressures- Static pressure before the water meter ranged from 15-43 psi. Pressures at the residences ranged from - 25 psi to 29 psi. Lots 6, 7, and 8 of the proposed subdivision would require booster systems immediately following the water meter since there pressures were negative. Since the residual pressures at each residence is less than 50 psi, an air gap system will be required for every lot. • Pipe size- The water main will be 12 inches and the laterals will be 2" with 1" water meters. • Design methodology -Hand calculations were provided that provided a rough estimate of maximum and minimum pressures throughout the site. The following methodology was done: • Static Pressure- The static pressure for each ode was determined by reducing the static pressures by the pipe Tread loss. The velocity component of the Bemoilli equation was ignored since the velocities associated with the domestic water use is around 0.17 fps for the water main. The determination of the pipe head loss was obtained from the Goulds Pumping guide which comply the losses per 100 feet of pipe PVC piping. The determination of equivalent lengths for bends, tees, etc., was obtained using a table formulated by Goulds Pumping guide. Conclusion The conclusion of the report was that domestic booster pumps and a fire pump will be required for certain lots. Mideation Measures/Monitorine: Not applicable. 14. Mineral Resources. Would the project: Page 37 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Potential Significant Impact a. Result in the loss or availability of a known mineral resource that would be or value to the region and the residents or the state? b. Result in the loss of availability of a locally -important mineral resource recovery size delineated on a local general plan, specific plan or other land use plan? Page 38 Less ThanLess Than No Significant Significant Impact w/Mitigation Impact Incorporated X M Discussion: The project site has no known mineral resources and the proposed development will have no significant impacts related to mineral resources. Mitieation Measures/Monitorine: Not applicable. 15. Cultural Resources. Would the project a. Cause a substantial adverse change in the significance of X a historical resource as defined in §15064.5? b. Cause a substantial adverse change in the significance of X an archaeological resource pursuant to § 15064.5? C. Directly or indirectly destroy a unique paleontological I X resource or site or unique geologic feature? d. Disturb any human remains, including those interred X outside of formal cemeteries? Discussion: A Cultural Resources Evaluation of the subject property was prepared to identify and evaluate cultural resources in the project area. The evaluation was conducted by Archaeological Resource Services, dated May 27, 2004. On May 18, 2004, Cassandra Chahan and Kristel Daunell of Archaeological Resource Service went to the property and performed a surface reconnaissance and evaluated the structures for historic significance. The evaluation states that the property is relatively flat in the northeast portion of the property where the structures are, and there are steep hills in the rest of the property. There is a small, seasonal drainage that passes through the southwestern tip of the property. The property is covered with very dense grasses that He flat, obscuring the soil. The grasses were pushed aside with a trowel in areas to observe the underlying soils. The evaluation further states that the perimeter of the property was walked, and the rest of the property was transversed back and forth from east to west. Areas near the drainages and flat and gently rolling areas were closely inspected. The report states that the steep areas were more difficult to examine, but are unlikely to contain archaeological sites, and will not be built upon. These areas were checked for evidence of prehistoric modification such as ground depressions or quarrying activities. The rocks were all composed of Franciscan melange, which is not typically used for mortar depressions or petroglyphs. No cultural modifications to the rocks were observed, and no evidence of prehistoric use was seen on the property. The evaluation concluded the following: No evidence of prehistoric activity was observed on the property. It is unlikely that an archaeological would be found, as the south half of the parcel is very steep and would have been unsuitable for prehistoric babitation. The structures on the northwest comer of the property compose a small farming complex. While none of the structures individually are of note, the concentration is typical of small farm in the area and will be recorded because it is planned to be removed. While the complex is typical of small fames in the region there is no attribute that would make it eligible for the National Register of Historic Places. The report further states that while archaeological monitoring is not warranted at this time, in the event that a concentration of artifacts or culturally modified soils deposits including additional trash pits older that fifty years of age, are discovered at any time during grading, scraping or excavation within the property, all work should be batted in the vicinity of the find and a qualified archaeologist should be contacted immediately to make an evaluation and that if warranted by the discovery of a concentration of artifacts or soil deposits, further work in the discovery area should be monitored by an archaeologist. Artifacts that are typically found -associated with prehistoric sites include humanly modified stone, shell, bone or other cultural materials such as charcoal, ash and burned rock indicative of food procurement or processing activities. Prehistoric domestic features include hearths, fire - Page 38 Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 39 Potential Less Than Less Than Na Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated pits, or house floor depressions whereas typical mortuary features are represented by human skeletal remains. Historic artifacts potentially include all by-products of human land use greater than 50 years old. Although unlikely, if human remains are encountered, all work must stop in the immediate vicinity of the discovered remains and the County Corner and a qualified archaeologist must be notified immediately so that an evaluation can be performed. If the remains are deemed to be Native American and prehistoric, the Native American Heritage Commission must be contacted by the Coroner so that a Most Likely Descendant can be designated. The report further goes on to discuss the potential historical significance of the existing structures. The report concluded that the residence and accessory structures were not historically significant. In addition, the City of Petaluma recently adopted Resolution No. 2005-198 N.C.S., which established a policy and associated procedures requiring all request for demolition of structures built in 1945 or earlier to be subject to review and approval of the Historic and Cultural Preservation Committee. In accordance with Us Resolution, the proposed demolition of the existing residence and other structures was reviewed by the Historic and Cultural Preservation Committee on February 9, 2006. The Committee concluded that the structures were not of historical significance and approved the demolition of the existing residence and other structures on the site. The structures have been demolished. Mitigation Measures/Monitoring: Not applicable. 16. Aaricultural Resources. In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Would the project: a. Convert Prime Farmland, Unique Farmland, or Famfland X of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b. Conflict with existing zoning for agricultural use or a X Williamson Act contract? C. Involve other changes in the existing environment which, X due to their location or nature, could result in conversion of Farmland, to non-agricultural use? Discussion: The subject property is located in the City limits, the city anticipated development of the site for urban uses. Therefore, the conversion of the existing farmland to residential use is considered to be less than significant. Mitigation Measures/Monitoring: Not applicable. 17. Mandatory Findinas of Sianificance. a. Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b. Does the project have impacts that are individually limited, but cumulatively --- -- considerable? ("Cumulatively considerable" means that the incremental effects of a Page 39 Yes No X Project Name: Pinnacle Ridge Subdivision File No. 05-ZOA-0029-CR Page 40 Potential I Less ThanI Less Than I No Significant Significant Significant Impact Impact w/Mitigation Impact Incorporated project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects ofprobable future projects)? d. Does the project have environmental effects which will cause substantial adverse effects X on human beings, either directly or indirectly? Discussion: The project with mitigation measures, would not have a significant effect on the environment, achieve short-term, to the disadvantage of long-temm environmental goals, have cumulative adverse impacts, or cause substantial adverse impacts on human beings.

Community Design DEVELOP INFILL SITES Infill development reduces pressure to develop greenfieids such as open space and farmland by reclaiming abandoned and underutilized sites and buildings. APPLICATION When selecting a development site, choose built urban settings where public infrastructure is already in place. Give preference to locations that are: in a downtown area; targeted for revitalization; close to major employment centers; and/or within an urban growth boundary or designated for development by the local jurisdiction. Also, locate the project within walking distance of a major transit stop; took for locations where good transit service already exists or work with officials to bring public transit to the area REQUIREMENT (up to 4 Points) a: Project is Located in a Built Urban Setting with Utilities in Place for Fifteen Years. (2 Points) Sanitary sewer line extensions and electric/gas utility connections are 1,000 feet (of piping) or less from any point of the property line of the tract being developed, or are already in place on-site. An alternative definition that could be used to satisfy this measure is a site in which at least 75% of the perimeter of the development site (the area where new homes are being built) borders existing development. b. Development is Located within 1/2 Mile of a Major Transit Stop. (2 Points) Walking distance must be via a public, standard and safe pathway. CODE ISSUES None VERIFICATION Accountability Form signed by the Builder, Developer or Architect stating compliance with this measure and documentation indicating distance to transit stop. Rater will conduct field observations. 2 CLUSTER HOMES AND KEEP SIZE IN CHECK DESCRIPTION On a given site, there are often many options for placing and orienting homes. Paying careful attention to land use and home size can help conserve natural resources. APPLICATION a. Cluster Homes for Land Preservation Two strategies for minimizing developed areas are clustering homes and building upward instead of outward. Besides preserving open space, certain clustered designs also use building materials and energy efficiently due to shared walls or roofs. The intent of clustering is to preserve meaningful open space (e.g., natural habitat that preserves wildlife corridors and minimizes habitat fragmentation) and promote compact walkable communities. b. Conserve Resources by Increasing Density Developments that allow for more households on a given site reduce pressure to develop greenfields or open space. Where there is access to public transit or commercial activities, GreenPoint Rated Single -Family Rating Manual, Version 3.0, April 2007 56 0. Community Design dense developments offer the advantage of shorter commutes, less dependence on cars, and walkable communities. c. Design Homes for Reasonable Size Homes can be designed to be comfortable and spacious without being excessively large; smaller, more compact homes conserve land, building materials and energy. REQUIREMENT (up to 15 Points) As described in the °Application° section above and: �g a. Cluster Homes for Land Preservation (2 Points) PM qp S� /p Plans must follow local development policies and show the deliberate grouping of a particular developments residential structures on a portion of the available land, preserving at least 30% of the site as protected open space. The open space created by cluster developments can be used in four commonways: exclusive use by residents (e.g., private trails, passive recreational areas), limited public low -impact recreational use (no golf courses), preservation of agricultural land, protection of wildlife habitat b. Conserve Resources by Increasing Density on Buildable Land (1 Point for 10 units per acre or greater plus 1 Point for each additional 5 unit per acre, up to a maximum of 4 Points) Units[Acre Points I 10 1 15 2 20 3 25 or more 4 Density is calculated as total number of dwelling units after construction, divided by the acreage of the entire tract down to one decimal point, minus dedicated acreage of public streets, right-of-ways, and easements; land occupied by non-residential structures; land excluded from residential development by law or agreement; or buffered wetlands and dedicated open space, down to one decimal point. GreenPoint Rated Single -Family Rating Manual, Version 3.0, April 2007 57 O. Community Design c. Home Size Efficiency [up to 9 Points] Home size calculations are based upon the following chart (same as NAHB Model Green Home Building Guidelines) and offer positive points for smaller homes.

Clustering may also be referred to as "open space development" or "conservation subdivision design.' New ordinances may require design standards and identify minimum open space and density standards. Credit may be earned for this measure independent of local code requirements. VERIFICATION Builder's documentation or Accountability Form verifying clear compliance with these measures. Rater will review plans, documentation and conduct field observations. 3 SUBDIVISION LAYOUT & ORIENTATION TO IMPROVE NATURAL COOLING AND PASSIVE SOLAR ATTRIBUTES DESCRIPTION Summer temperatures in neighborhoods that have large expanses of pavement exposed to the sun can be several degrees warmer than neighborhoods with shaded pavement Homes that are oriented without regard to solar access may require excessive energy to heat and cool. Planning strategies that take solar access into account can address these concerns_ APPLICATION Plan streets and lot layouts to provide for shading of streets by trees to reduce this "heat island" effect Keeping streets narrow will make them easier to shade by trees and will contribute to traffic calming, improving safety. Orient homes on an east -west access to facilitate passive solar design, reduce heating and cooling energy use, and facilitate placement of rooftop solar electric and solar thermal systems. Use alley ways, greenbelts, and other methods to provide goad solar access to the homes. GreenPoint Rated Single -Family Rating Manual, Version 3.0, April 2007 58 O. Community Design REQUIREMENT (Up to 10 Points) As described in the `Application" section above and: Build It Green will make a judgment on the use of this criterion in response to a submission by the builder and/or rater. CODE ISSUES Narrow streets and tree coverage will be regulated by local authorities. California has several laws designed to encourage solar access and prevent restrictions on solar energy systems. These laws address municipal restrictions, residential landscaping, and homeowner association restrictions. Solar Rights Act amended in 2004 by AS 2473 (Civil code section 714, Health and Safety Code section 17959.1, Government code section 65850.5): Prohibits local governments from restricting the installation of a solar energy system based on aesthetics. Solar Rights Act amended in 2003 by AB 1407 (Civil Code section 714): Requires that public entities do not place unreasonable restrictions on the procurement of solar energy systems when applying for state-sponsored grants and loans. Solar Shade Control Act of 1979 (Public Resources Code sections 25980-25986): addresses shade from neighboring vegetation. Solar Rights Act,of 1978 (Civil Code section 714): Homeowner associations must not place unreasonable restrictions on homeowners wishing to install solar energy systems. Solar Easement Law (Civil code sections 801 & 801.5): Provides the opportunity to protect future solar access via a negotiated easement with neighboring property owners. Many cities and counties have local solar access laws and guidelines. For regional specific information on these and financial incentives, including tax credits, that make solar power more affordable, go to www.dsireusa.org. VERIFICATION Buildets documentation verifying clear compliance with these measures. Rater and Build It Green will review plans, documentation and conduct field observations as necessary. 4 DESIGN FOR WALKING AND BICYCLING DESCRIPTION Walking and bicycling are inexpensive, healthy forms of transportation but they are often Incompatible with conventional car -based development patterns. Convenience, safety and aesthetics are key factors in promoting travel by foot and bicycle. APPLICATION a. Provide Pedestrian Access to Neighborhood Services Build pedestrian -friendly communities that combine residential and commercial spaces so that people can shop, play and meet their daily needs close to where they live. b. Include Pedestrian Pathways that Connect to Recreation Many new home developments include plans for new roadways and pedestrian paths. Where applicable, connect walkways to places of interest, such as parks, stores, and recreation areas. Use landscaping buffers to separate sidewalks from roadways. c. Design Traffic -Calming Elements to Encourage Walking and Bicycling Design 10 -foot vehicle travel lanes, rather than the standard 12 -foot lanes, to discourage fast driving. Use the remaining right of way for bike lanes. Consider rumble strips, bulbouts and raised crosswalks to reduce speeding REQUIREMENT (up to 5 Points) As described in the 'Application' section above and: CreenPoint Rated Single -Family Rating Manual, Version 3.0, April 2007 59 O.

APPLICATION Design all home entrances so that outside callers can be seen from inside the home. Place tall windows with low sill heights at front doors, or use transparent panels in the doors so any occupant, including children and the disabled, can view all visitors. Orient porches to streets and public spaces to provide natural surveillance. Help keep the community safe and neighborly by orienting windows so that residents can easily view and feel comfortable using nearby areas such as outdoor benches, pathways, pocket parks, children's play areas and other features that promote socializing REQUIREMENT (up to 3 Points) As described in the °Application° section above and: a. All Home Front Entrances Have Views from the Inside to Outside Callers (1 Point) Sidelights, doors with windows, double -height peepholes or equivalent features that allow occupants of all heights and capacities to recognize callers.

REDUCE HEAT-ISLAND EFFECT DESCRIPTION Cool site measures are most important in urban environments where large areas of asphalt and buildings retain heat and increase temperatures in the surrounding environment APPLICATION Install light-colored, high albedo materials (solar reflectance index >= 0.3) for at least 50% of site's non -roof impervious surfaces. OR Design and install overhangs, shading elements, trees and shrubs (or preserve existing trees and shrubs) to shade at least 50% of sidewalks, patios, and driveways within 50 feet of house (based on noon on June 21 at 5 years' growth). REQUIREMENT (1 Point) As`described in the 'Application' section above and: At least 50% of the paved site area, excluding the building and building footprint, incorporate one or more of the following cool site techniques: • Covered parking (underground or under overhangs/awnings) • Light-colored paving materials or pavers with an albado of 0.30 or greater (color equivalent of uncolored concrete) • Pervious concrete/paving (poured or tile) that are at least 50% pervious • Open -grid paving systems (defined as having less than 50% imperviousness and containing vegetation in the open cells) • Granite or crushed rock for walkways, driveways and paths • Resin -modified emulsion pavement. • Subsurface vehicular support systems with turf covering Design and install overhangs, shading elements, trees and shrubs (or preserve existing trees and shrubs) to shade at least 50% of sidewalks, patios, and driveways within 50 feet of house (based on noon on June 21 at 5 years' growth). Shading from buildings, trees or other structureslobjects not on the building site are not eligible for this measure unless a shade study is conducted. The study should calculate coverage at 1 cam, noon and 3pm, and the arithmetic mean of these three values will be used as the effective shaded area. CODE ISSUES Follow all applicable local codes, ordinances and community covenants. Local jurisdictions may or may offer credit on stormwater control requirements due the use of some of these measures. VERIFICATION Accountability Form signed by the Builder, Developer or Architect stating compliance with this measure and documentation indicating distances. Rater will conduct field observations. A2. BUILD ON EPA DESIGNATED BROWNFIELD SITE DESCRIPTION The U.S. Environmental Protection Agency (EPA) states that brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or GreenPoint Rated Single -Family Rating Manual, Version 3.0, April 2007 62 P. Innovation potential presence of a hazardous substance, pollutant, or contaminant. Common varieties of brownfields include such properties as gas stations, manufacturing facilities, industrial yards, and more. The EPA estimates that there are more than 450,000 brownfields in the U.S. Cleaning up and reinvesting in these properties increases local tax bases, facilitates job growth, utilizes existing infrastructure, takes development pressures off of undeveloped, open land, and both improves and protects the environment APPLICATION Work with local government and take advantage of EPA's Brownfields program s grants, loans and training to support environmental assessment, cleanup, and job training activities in the effort to develop such sites for residential use. REQUIREMENT (3 Points) As described in the 'Application' section above and: Site must be designated as a brownfield by a state or national agency and be fully remediated and certified for residential use. Grayfields or previously developed sites do not qualify. CODE ISSUES Builder must abide by all local, state and federal codes and requirements in remediating and developing this site. VERIFICATION Builder's documentation of Brownfield designation and appropriate remediation. B. Foundation B1. INSTALL A FOUNDATION DRAINAGE SYSTEM 1911*11101ir1161 A comprehensively designed and Installed perimeter foundation drainage system will divert surface and subsurface water away from the house, and limit water seepage through the foundation walls, crawlspace and basement slab. APPLICATION Use best practices to design, specify on plans, and install a perimeter drain for all footings and a waterproof membrane or drainage panel on the exterior of all foundation walls. Slope to discharge to daylight, dry well, or sump pit. The drain system of perforated pipe should be installed below the level of the basement or crawispace slab. REQUIREMENT (2 Points) As described in the °Application° section above and: This measure applies equally to slabs, crawlspaces or basements. Pipe should be wrapped with filter fabric and surrounded with a prescribed minimum of (IRC(D 12 inches x 6 inches, exterior) clean gravel, crushed stone, or recycled aggregate. If the outfall is to a sump pit, and the pit requires a pump, pipe should be installed for outfall 10 feet away from foundation wall and so that it does not cause localized erosion. CODE ISSUES Builder and Professional Engineer must abide by all local and state codes and requirements in installing the drainage system. A common issue to be aware of is a common requirement of separation of French drain system from gutter downspouts. VERIFICATION Rater will review details on plans and will conduct field observations.

Pinnacle Homes is planning the demolition of the main residence and several related bams, sheds and other structures, which could impact special -status bat species potentially roosting within the buildings and/or trees that occur on the site. This survey is a follow-up to my habitat assessment and survey conducted July 14, 2004. Site Description Seven buildings occur on-site which will be demolished to accommodate proposed development of the site, including: 1) a single -story stucco ranch house, 2) a wood -sided water tank tower, 3) a wood -sided garage, 4) a small wood -sided shed, 5) a large metal -sided barn, 6) a large wood -sided horse barn, and 7) a wood - sided horse stable. The residence has been unoccupied for several years, and the remaining structures have been unused for a longer period (Weimeyer, personal communication). Several trees, primarily non-native ornamentals, occur in proximity to the residence, barn, garage and water tank tower. Please refer to our 2004 report for additional details about the location, setting, and existing conditions (Wildlife Research Associates, 2004). RECEIVED NOV 6 6 2008 COMMUNITY DEVELOPMENT DEPARTMENT Bat Predemolition Survey — 2762 1 Street, Petaluma Page 1 of 3 Wildlife Research Associates Methods On March 15, 2006, all structures were examined for evidence of bat roosting activity, as shown by openings suitable for entry by bats, accumulations of fecal pellets, urine streaking, or staining of exterior wall and window surfaces. The two trees labeled 1 and 2, adjacent to the main residence, were surveyed, for suitable roost cavities. The oaks (Quercus sp.) located on the hill above the horse paddocks was also surveyed. Results The physical condition of the buildings on the site remains similar to those observed in 2004, although the structures appear to have decayed further. Except for a few fecal pellets on die outside of the residence at the open carportjunction with the residence, none of the structures showed past or present evidence of either day or night roosting activity by bats. No staining, fecal pellets, live or dead bats, or characteristic odor of bat urine was observed in or around any of the other structures. No bam owls were observed in any of the buildings, however pigeons (Cohimba livid) were observed in the large barn behind die residence. At the time of our survey in 2004, the residence, a single -story stucco -sided building, contained only two potential openings for bats into the structure — the two attic gable vents. During this survey, two new openings were observed; 1) a Bole in the soffit at the right side of the house, and 2) a hole in the rafter blocking on the front right side of the structure. Hole #1 appears to have been made by a vent or drain that bad fallen from the soffit surface. Hole 42 was made apparently made by woodpeckers, likely an acorn woodpecker (Avialanerpes formicivorais), or roof rats (Rattus rattus). A trail of staining was observed leading from an adjacent tree branch, along a conduit pipe, into the opening, indicating use by rats and/or house mice (Daus muscuhrs). No bat fecal pellets were observed. An inspection of the attic area showed no evidence of past or present use by bats. Large numbers of rat (Ratters sp.) fecal matter was found in the attic and in some of the interior rooms of the residence. None of the trees surrounding the buildings appeared to contain cavities suitable for roosting by bats. The cluster of oaks on the hill behind the buildings did contain suitable openings. Discussion Although the age, construction and condition of the structures all provide elements bats find suitable for day and/or night roosting activity, none of the structures showed evidence of past or present use by bats. Except for the attic of the residence and the garage, the buildings were too open to provide suitable day -roosting habitat for bats. Although no specific tree roosts were observed, it is possible that potentially suitable roost cavities occur in the oaks on the hill behind the buildings. If development of the site will occur within 50 feet of the trees, loss of potential tree -roost habitat for several bat species, including colonial, and solitary, obligate tree - roosting bats could occur. Because tree -roosting bats move frequently among roost trees, surveys showing absence from a suitable roost cavity have limited temporal validity. Also, because bats roosting in bark crevices are very hard to detect, results of focused surveys to determine presence or absence of bats from tree roosts should be interpreted cautiously. Other methods to reduce or eliminate impacts (such as seasonal tree removal or trimming, staged removal of limbs and hunk, and removal of adjacent trees not providing habitat prior to diose with suitable roost characteristics) should be combined with identification of suitable roost characteristics, which Gvill require a tree survey at a later date. Bat Predemolition Survey— 2762 1 Street, Petaluma Page 2 of 3 Wildlife Research Associates Recommendations A) The oak trees described in this report shall not be removed without fust having a qualified bat biologist conduct emergence surveys during appropriate dates to determine presence or absence of day -roosting bats. No machinery shall be parked or used beneath the trees, to prevent fumes and noise from impacting bats that may be roosting inside tree cavities. B) If no bats are observed emerging from cavities in the oaks, the trees shall be removed within 48 hours. If bats are observed, then tree removal shall occur only between February 15 and April 15, or between August 15 and October 15, in order to avoid impacts to non-volant young or torpid adult bats that may be roosting in cavities in the trees.

GOLDEN BEAR BIOSTUDIES 11 8/24/04 BIOLOGICAL ASSESSMENT: PITNT_NACLE RIDGE PUD, PETALUMA 1 SUMMARY This report presents the findings of a survey for special status species and sensitive natural communities at the proposed Pinnacle Ridge PUD project site (referred to as "tire site") located in southern Petaluma, California (Figure 1). The site is 15.56 acres and located at 2762 1 Street, Petaluma, California (APNil 019-401-019). No special status plant species were observed at the site during the field surveys conducted by Darren Wiemeyer, Staff Ecologist, on June 28th and August 2"d, 2004. Because special status plant species surveys were not conducted in early spring, it is recommended that special status plant species surveys be conducted in early and mid -spring of 2005. A large valley oak tree (Quercus lobata) is located in the center of the site. Evidence of recent bane owl (Tyto alba) activity was observed in the large barn (Figure 4). No other raptors were observed actively nesting at the site and no raptor nests were observed. Although not considered significant, the project would result in the loss of foraging habitat for several raptor species. A bat habitat assessment and survey conducted at the site determined that none of the structures on site showed evidence of past or present use by bats, but the structures all provide elements that bats find suitable for day and/or night roosting activity (Wildlife Research Associates, 2004) (Appendix D). Recommendations are proposed in this report to avoid "take" of potential sensitive bat species that may occupy the site in the future. The majority of the project site consists of non-native grassland habitat with small pockets of oak woodland habitat. Special status habitats in the form of a seasonal drainage were present at the far southwest comer of the site. This seasonal drainage is a Section 404 CWA federal jurisdictional wetland (i.e. Waters of the U.S.). This seasonal drainage will be preserved within an urban separator (Figure 4). Within the western portion of the site are two ranch roads, situated in upland grassland habitat, that have eroded and now convey surface run off down slope into a roadside drainage ditch (Figure 4). No wetland vegetation or other wetland indicators were observed within any portion of these eroded roads. The roadside drainage ditch, which flows along the eastern boundary of the site, does exhibit riparian vegetation at the northern end in front of the residence (Figure 4). Surface water that flows through this roadside drainage ditch immediately enters an underground stoma drain system that apparently flows north to the Petaluma River. Therefore, this roadside drainage ditch has no surface connection with jurisdictional wetlands or waterways. The preliminary investigation of these features has determined that the eroded roads and the roadside drainage ditch would not be considered jurisdictional by the United States Anny Corps of Engineers (USACE), the California Department of Fish and Game (CDFG), or the Sana Francisco Bay Regional Water Quality Control Board (SFBRWQCB). It is recommended that die USACE, CDFG, and SFBRWQCB conduct site visits to make a final determination on jurisdiction. A General Permit for Storm Water Discharges from Construction Activities would be required through the SFBRWQCB. GOLDEN BEARBIOSTUDIES 1 8124104 BIOLOGICAL ASSESSMENT: PLNNACLE RIDGE. PUD, PETALUMA 2 INTRODUCTION 2.1 BACKGROUND This report presents the findings of a survey for special status species and sensitive natural communities at the proposed Pinnacle Ridge FUD project site located in southern Petaluma, California (Figure 1). 2.2 PROSECT DESCRIPTION The Pinnacle Ridge PUD project site is located at 2762 I Street, Petaluma, California (Figure 1). The Assessor's Parcel Number is 019-401-019. The site is situated in the foothill area on the southern end of Petaluma and is flanked by residential development to the north (Figure 4). To the east is rural residential single-family homes and to the south and west is currently open grasslands that has historical been used for grazing (Figure 4). The site is within the Petaluma River watershed (Figure 2). The project site is approximately 15.56 -acres in size and ranges from 140 to 330 feet in elevation (Figures 2 &z 4). The area surrounding the project site is mostly undeveloped ranchland, with low density single family homes to the east across I street, and a newer residential subdivision directly adjacent to the north. The majority of the site consists of open grassland that has been used as grazing Iands up until the recent past (Figure 4). There are seven building on site. They include a single -story stucco ranch house, a wood -sided water tarns tower, a wood -sided garage, a small wood -sided shed, a large barn, a large wood -sided horse barn, and a wood -sided horse stable. The residence has been unoccupied for two years, and the remaining structures have been unused for a longer period of time. The proposed project consists of the demolition of all structures on site. Eleven single-family homes will be built and a cul-de-sac road will be constructed to access these homes. A 5.91 acre area at the southern end of the site will be preserved within an urban separator (Figure 4). 2.3 DESCRIPTION OF ANY UNIQUE SITE CHARACTERISTICS AND THEIR TREATMENT A seasonal drainage, which is considered a Section 404 CWA federal jurisdictional wetland, intersects the far southwest comer of the site (Figure 4). Up slope and off site of this seasonal drainage is an unstable slope with evidence of slides and soil movement. A grassy swale originates below the slide. This drainage becomes moderately eroded on-site, but then returns to a grassy Swale before flowing off site to the northwest. Just down slope and off site, the swale becomes more defined and less sloped, and is vegetated with cartails and most likely other wetland plant species. This seasonal drainage is located within the proposed urban separator and will not be impacted as part of this proposed development. GOLDEN BEAR BIOSTUDIES 2 8124104 BIOLOGICAL ASSESSMENT: PfNNACLE RIDGE PUD, PETALUNIA Within the western portion of the site are two ranch roads, situated in upland grassland habitat. The roads have eroded and now convey surface run off down slope into a roadside drainage ditch (Figure 4). No wetland vegetation or other wetland indicators were observed within any portion of these eroded roads. The roadside drainage ditch, which flows along the eastern boundary of the site, does exhibit riparian vegetation at the northern end in fiont of the residence. Surface water that flows through this roadside ditch immediately enters an underground storm drain system that apparently flows north to the Petaluma River. Therefore, this roadside drainage ditch has no surface connection with jurisdictional wetlands or waterways. The preliminary investigation of these features has determined that the eroded roads and the roadside drainage ditch would not be considered jurisdictional by the USACE, the CDFG, or the SFBRWQCB because they are man-made artifacts not connected to existing natural wetlands. However, it is recommended that the USACE, CDFG, and SFBRWQCB conduct site visits to make a final determination on jurisdiction. The large bam near the residence is currently being utilized as a roost by one or more barn owls (Figure 4). Although no barn owls were observed, fresh regurgitated prey pellets were observed though out the barn. Several mature trees are located on the southern portion of the site. They consist of valley oak (Quercus lobata), California bay (Unibcllularia californica), and coast live oak (Quercus agrifolia). The majority of these trees are situated in the proposed urban separator and will not be impacted. The valley oak is situated within a home lot, but is outside of the building envelope, so it appears it will not be impacted. 2.4 SCOPE As part of the standard CEQA review process, the City of Petaluma Planning Department will review this Biological Assessment Report to determine impacts and mitigation to biological resources. The scope of this report is limited to determining if the project will affect special status habitats (e.g. riparian habitat or wetlands) and/or species. Please refer to endnotes` for definitions. 2.5 REGULATORY CONTEXT A number of state and federal agencies, including U.S. Fish and Wildlife Service (USFWS), California Department of Fish and Game (CDFG) and the U. S. Army Corps of Engineers (USACE), have regulatory authority over special status species and sensitive habitats. Please refer to the endnotes" for further discussion of regulatory aspects. 2.6 LITERATURE REVIEW Information on the biology, distribution, taxonomy, legal status, and other aspects of the special - status species was obtained from documents on file in the library of Golden Bear Biostudies. Standard references used for the biology and taxonomy of plants included Hickman, ed., 1993 and Best et al, 1996.

They were conducted in a manner to identify any rare or endangered species that may be present during the summer blooming period (CDFG, 2000; USFWS, 1996). Most of the spring annual plants would have bloomed and died months before these surveys, but perennials and late blooming plants would have been identifiable to species. Because early spring surveys were missed, early spring 2005 surveys would need to be conducted next year to identity all rare or endangered species that may be present. Field surveys were conducted when most rare or endangered species that could occur in habitats at the site would be both "evident" and "identifiable". The surveys were floristic in nature and not based on the occurrence of habitat or other physical features. The survey was conducted using systematic field techniques in all habitats of the site to ensure a reasonably thorough coverage of potential impact areas. A meandering pattern was wallced through each habitat to ensure that all areas were viewed. Given the late season limitations, all plants at the site were identified to the level necessary to ascertain whether they were "suecial status species." 3.2 E1NmALS Field surveys were conducted on and June 28`h and August 2"d, 2004. Surveys were conducted to determine if habitats supported special status animal species. Protocol Ievel surveys for potentially occurring special status animal species were not conducted. This level of survey does not seem warranted with the absence of critical habitats and being excluded from the range of the California tiger salamander. The determination of presence for animal species possibly occurring was based on habitat assessments, literature review, and queries through CNDDB. Mr. Greg Tatarian with Wildlife Research Associates performed a bat habitat assessment and survey at the site to determine if any special status bat species could potentially occur at the site. The results of this bat habitat assessment and survey is included in Appendix D. A raptor nest survey was conducted at the site on June 28, 2004. All trees and other potential roosts were observed to determine if they are currently, or historically, been used as nesting habitat by raptors. 3.3 WETLANDS Standard USAGE wetland delineation procedures as described in the USACE Wetlands Delineation Manual (Environmental Laboratory, 1987) were used to determine whether any wetlands were present on site. A routine on-site investigation was conducted on June 28a', 2004 using the plant corium ity assessment method. Detailed application of the three -parameter approach (vegetation, hydrology and soils) was applied to areas that could potentially be considered wetlands. GOLDEN BEAR,BIOSTUDIES 9 8124104 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALUMA 4 RESULTS 4.1 PLANT COMMUNITIES & HABITATS Where possible, the vegetation has been classified according to the California Natural Diversity DataBase's Descriptions of the Terrestrial Natural Communities of California (Holland, R. F, 1986). The California Natural Diversity DataBase (CNDDB) is a computerized inventory of the locations of populations of rare and threatened plants, animals and natural communities in California. These "elements of natural diversity" are monitored by CNDDB to assure that California's rich biological heritage is adequately represented in their inventory. A list of the flora observed on site during the spring surveys is included in Appendix C. The 15.56 -acre site consists primarily of non-native grasslands with a few localized areas of oak woodland (Figure 4). The soil type consists of Los Osos clay learn and Pleasanton loam (Miller, 1972) (Figure 3). A seasonal stream (waters of the U.S.) is located at the southwest corner of the site (Figure 4). A roadside drainage ditch is located along the eastern boundary of the site (Figure 4). A list of the flora observed at the site is provided in Appendix C. 4.1.1 Seasonal Drainage There is a seasonal drainage, which is considered a Section 404 CWA federal jurisdictional wetland, intersects the far southwest comer of the site (Figure 4). This seasonal drainage does not possess significant aquatic or stream habitat values. This seasonal drainage did not exhibit any wetland characteristics or riparian habitat, but it does convey surface run off. Up slope and off site of this drainage is an unstable slope with evidence of slides and soil movement. A grassy swale originates below the slide area. This swale becomes moderately eroded on-site, but then returns to a grassy swale before flowing off site to the northwest. Just down slope and off site, the swale becomes more defined and less sloped, and is vegetated with cattails (Typha latifolia) and most likely other wetland plant species. This seasonal drainage is located within the proposed urban separator and will not be impacted as part of this proposed development. 4.1.2 Roadside Drainage Ditch A roadside drainage ditch flows north along the eastern boundary of the site and exhibits riparian vegetation throughout the northern portion of the drainage ditch. Riparian vegetation was comprised mostly of non-native species, primarily white poplar (Popir&is alba), Himalaya berry (Rubes procerus), and periwinlde (Vinca major). Surface water that flows through this roadside ditch immediately enters an underground storm drain system that apparently flows north to the Petaluma River. Therefore, this roadside drainage ditch is a man-made artifact that has no surface connection with jurisdictional wetlands or waterways. GOLDEN BEAR BIOSTUDIES 10 8/24/04 BIOLOGICAL ASSESSINIENT: PINNACLE RIDGE PUD, PETALUtvL4 The preliminary investigation of this feature has determined that the roadside drainage ditch would not be considered jurisdictional by the USACE, the CDFG, or the SFBRWQCB since it is not connected to existing natural wetlands or waterways. It is recommended that the USACE, CDFG, and SFBRWQCB conduct site visits to make a final determination on jurisdiction. 4.1.3 Non-native Grassland (42200) This community is the most widespread at the site (Figure 4). There are a few localized areas within the non-native grassland habitat that could be considered oak woodland (71100). One area consists of a clump of coast live oaks (Quercus agrifolia), another area consists of a chump, of California bay (Urnbellularia californica), and a third area has a single valley oak tree (Quercus lobata). Description: This community occurs across the majority of the site. It forms a dense to sparse cover of annual grasses with flowering cuhms 0.2-0.5 (1.0) m high. It is often associated with numerous species of showy -flowered, native annual forbs ("wildflowers"), especially in years of favorable rainfall. Germination occurs with the onset of the late fall rains; growth, flowering, and seed -set occur from winter through spring. With a few exceptions, the plants are dead through the summer -fall dry season, persisting as seeds. Typical species included perennial ryegrass (Lolium perenne), slender wild oat (4vena barbata) soft chess (Brornus mollis), Harding grass (Phalaris aquatica), sow thistle (Sonchus oleraceus), and Italian thistle (Carduus pycnocephalus). Most of the other species were weedy annual forbs and grasses (Appendix D). Site Factors: This vegetation usually occurs on fine -textured, usually clay soils, moist or even waterlogged during the winter rainy season and very dry during the summer and fall. Oak Woodland (71100) is often adjacent on moister, better -drained soils. The weedy nature of the flora is likely due to years of grazing by domestic livestock up to the recent past and the spread of aggressively competitive exotic plants. Geographic Distribution: Statewide this vegetation is found in valleys and foothills of most of California, except for the north coastal and desert regions. It usually occurs below 3,000 feet, but reaching 4,000 feet in the Tehachapi Mountains and interior San Diego County. It intergrades with Coastal Prairie (41000) along the central coast. 4.2 NVILDLWE Wildlife that utilizes grasslands is complex and diverse. A diverse microbial life exists in grasslands which serves the important function of humus formation, and burrowing and surface animals such as mice, moles, shrews, gophers, earth worms and a host of others, provide an essential food resource to snakes, manunals of wider habitat range, and to raptorial birds (hawks, kestrels, kites, shrikes, and owls). Raptorial birds, as well as many other smaller perching birds associated with grasslands, such as house finch, meadowlark, quail, and sparrows also make use of this habitat type. The non-native grasslands on site are much Iess diverse than undisturbed, native grasslands and provide less habitat value because of the history of grazing. GOLDEN BEAR BIOsTUDIEs 11 8/24/04 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALUMA 4.3 SPECIAL STATUS PLANTS No special status plants were observed during the field surveys. The site lacked appropriate habitats for virtually all of the special status species listed in Table 1. The absence of specialized habitats, such as serpentine soils, vernal pools, or salt marshes, greatly restricts the possibility of finding rare and endangered species in the disturbed grazing land. The history of grazing and the spread of exotic, weedy species results in the replacement of the native flora on sites like the project site, as it has throughout California. Due to the time of year, it was not possible to state with absolute certainty that early spring -blooming special status plants were not present. Although these species are not likely to occur due to the existing condition of the site and lack of suitable habitat, it is recommended that special status plant surveys be conducted in early and mid -spring of 2005. A large valley oak tree is situated in the center of the (Figure 4). The valley oak is situated within a home lot, but is outside of the building envelope, so it appears it will not be impacted. Provisions should be made to avoid damage to its roots and drip line, and to prevent increased soil moisture around the tree from landscape irrigation. 4.4 SPECIAL STATUS ANIMAL SPECIES Since the site does not have any native riparian habitat, perennial streams or ponds, or salt marsh habitat, most species listed in Appendix B would not have the potential to occur on site. The only special status animals that were observed during field visits were a female sharp -shinned hawk perched in a eucalyptus tree, a white-tailed lute actively foraging, and evidence of a barn owl roosting in the large barn. The non-native grasslands do provide adequate foraging habitat for various raptor species (i.e. sharp shinned hawk, red shouldered hawk, red-tailed hawk, white- tailed lute, barn owl). No raptor nests were observed during field visits. The project would result in the loss of foraging habitat for several raptor species, but would not result in the "take" of raptor species. The seasonal drainage on site lacks perennial flows or pools, does not have any wetland or riparian vegetation, and does not have undercut banks. Therefore, this seasonal drainage does not provide the habitat requirements necessary for California red -legged frog, foothill yellow - legged frog, California freshwater sluimp, western pond turtle, or northwestern pond turtle. Furthermore, it does not have a gravel substrate or any potential spawning habitat on site or upstream to provide habitat for coho salmon or steelhead. The site is outside of the potential range of the California tiger salamander. Tri -colored blackbirds and great blue herons could potentially utilize the wetland habitat downstream and off site of the seasonal drainage, but this habitat will not be impacted. Milkweed (Asclepias spp.) and violet (Viola spp.) were not observed at the site, so it is unlikely that the monarch butterfly, callippe silverspot butterfly, or Myrtle's silverspot would utilize the site. Cream cups (Platystemon californicus) and serpentine grasslands were not observed at the site, so it is unlikely that Opler's longhorn moth would utilize the site. GOLDEN BEAR BIOSTUDIES 12 8/24/04 BI0L0GIC.AL ASSESSMENT: PINNACLE RIDGE PUD, PETALUiiA The large barn on site has been and appears to continue to provide roosting habitat for one or several barn owls. White wash and regurgitated owl pellets provide evidence of recent barn owl activity in the large barn (Figure 4). There was evidence of small rodents utilizing the site, but there were no ground squirrel burrows or other large burrows on site that could provide habitat for burrowing owls. There was no evidence of American badger or burrowing owls utilizing the site. A bat habitat assessment and survey conducted at the site determined that none of the structures on site showed evidence of past or present use by bats, but the structures all provide elements that bats find suitable for day and/or night roosting activity (Wildlife Research Associates, 2004). Details regarding the bat habitat assessment and survey are included in Wildlife Research Associates report entitled Results of Bat Habitat Assessment and Survevs. 2762 I Street. Petaluma, California, dated Judy 21, 2004 (Appendix D). The demolition of these structures would result in the loss of potential roosting habitat for sensitive bat species. 4.5 SPECIAL STATUS HABITATS Special status habitats it the form of a seasonal drainage occurs on site. The seasonal drainage, which is considered a Section 404 CWA federal jurisdictional wetland, intersects the far southwest comer of the site (Figure 4). This seasonal drainage does not possess significant aquatic or stream habitat values. This seasonal drainage did not exhibit any wetland characteristics or riparian habitat, but it does convey surface nm off. Up slope and off site of this drainage is an unstable slope with evidence of slides and soil movement. A grassy swale originates below the slide area. This swale becomes moderately eroded on-site, but then returns to a grassy Swale before flowing off site to the northwest. Just down slope and off site, the Swale becomes more defined and less sloped, and is vegetated with cattails (Typba latlfolia) and most likely other wetland plant species. This seasonal drainage is located within the proposed urban separator and will not be impacted as part of this proposed development. GOLDEN BEAR BIOSTUDIES 13 8/24104 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALUMA 5 POTENTIAL IMPACTS AND RECOMMENDED MITIGATION 5.1 SIGNIFICANCE CRITERIA The determination of sitmificance of impacts to biological resources involves an evaluation of the context in which the impact may occur and the intensity and extent of the impact's effect. The significance of potential impacts is assessed at a site-specific scale and in the larger regional context. The project's effect on biological resources would be considered significant if the project results in: O Alteration of unique characteristics of the area, such as sensitive plant communities and habitats (i.e. serpentine habitats, wetlands, riparian habitats). a Adverse impacts to special status species • Adverse impacts to important or vulnerable resources as determined by scientific opinion or resource agency concerns (i.e. special status habitats; e.g. wetlands). 4 Interference with migratory routes. 5.2 IMPACTS AND RECOMMENDED MITIGATION POTENTIAL IMPACT l . IMPACT TO BARN OWL AND SAT SPECIES Potentiallv Significant The project will result in the demolition of all existing structures on site. The age, construction and condition of the structures all provide elements that bats find suitable for day andlor night roosting activity. Despite this, none of the structures showed evidence of past or present use by bats. In addition, the large barn provides roosting habitat for barn owls. It is possible that potentially suitable roost cavities occur in the oak trees on site. If development of the site will occur within 50 feet of the trees, loss of potential tree -roost habitat for several bat species, including colonial, and solitary, obligate tree -roosting bats could occur. Mitigation Mitigation I.1. The rvindoti, .screen mesh covering the gable vents of the residence is mostly intact, but should be maintained, or the gable vents sealed with p1jnmod, until the building is demolished. The residence should be demolished within 30 days of this survey. After that time, it is possible that bats could begin to day roost in the building. GOLDEN BEAR BIOSTUDIES 14 8124/04 t BIOLOGICAL. ASSESSINIENT: PINNACLE RIDGE PUD, PETALUMA Mitigation 1.2. If demolition of the residence call not occur r-vithin 30 days of this survey, then the building should be surveyed by a qualified bat biologist possessing a Memorandum of Understanding with the CDFG, no more than 2 weeks before demolition, to avoid "take" of any bats that may have begun to use the structures for day -roosting .subsequent to this assessment. It is recommended that demolition take place between now and October 15, 2004, in order to avoid project delays caused by bats that may have begun to roost in the structures) during the fall (they may becoure seasonally torpid, which would delay humane eviction until mid-February, 2005). Mitigation 1.3. No trees or limbs of the oak trees described in this report shall be removed without first having a qualified bat biologist conduct emergence surveys to determine presence or absence of day roosting bats. No machinery shall be parked or used beneath the trees, to prevent fianes and noise f•onr impacting bats that nuty be roosting inside tree cavities. lblitigation 1.4. To avoid "take" of the barn oivl in the large barn, the barn should be demolished no later that Febr Miry 15. Impacts will be less than significant by implementing these measures and complying with agency conditions. POTENTIAL IMPACT 2. CONSTRUCTION ACTIVITIES WILL RESULT IN THE LOSS OF ROADSIDE DRAINAGE DITCH Potentialiv Sienificant The preliminary investigation of this feature has determined that the roadside drainage ditch would not be considered jurisdictional by the USAGE, the CDFG, or the SFBRWQCB. It is recommended that the USACE, CDFG, and SFBRWQCB conduct site visits to make a final determination on jurisdiction. If any of these agencies exerts jurisdiction over the roadside drainage ditch, then a permit would be required though that agency for impacts to the roadside drainage ditch. In addition, habitat mitigation may be required for the loss of this habitat. Mitigation 1 -litigation 2.1. Request site visits by the USACE, CDFG, and SFBRTVQCB to make final determination regarding jurisdiction of the roadside drainage ditch. Mitigation 2?. If determined Jurisdictional, obtain permits though the appropriate regencies (USA CE, CDFG and/or SFBI?WQCB) for the impacts to the roadside drainage ditch. GOLDEN BEAR BIOSTUDIES 15 $124104 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALUMA Mitigation 2.3. If determined jurisdictional, then mitigation for the loss of habitat in the roadside drainage ditch will be required through the appropriate agencies (VSAC1 CDFG, and/orSFBRL(rOCB). Mitigation 2.4. Conduct construction activities during stmmter months when the roadside drainage ditch is d7y to prevent impacts to water qualihr. Impacts will he less than significant by implementing these measures and complying with agency conditions. POTENTIAL IMPACT 3. CONSTRUCTION ACTIVITIES MAY RESULT IN EROSION AND SEDIMENTATION OF DOWNSTREAM AQUATIC HABITATS Sediment transport from construction activities to the roadside drainage ditch and downstream aquatic habitats can have deleterious effects on aquatic organisms in these aquatic habitats and result in violations of State and Federal water quality regulations. Mitigation Mitigation 3.I. Ensure that best management practices are adopted in order to minimize the amount ofseditnent leaving the site during construction activities. Mitigation 3.2. Obtain a General Permit for Storm Water Discharges from Construction Activities through the SFBR 1,VOCB. rbliagation 3.3.

GOLDEN BEAR BIOSTUDIES 18 8/24/04 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALU'MA ENDNOTES 'DEFINITION OF SPECIAL STATUS PLANTS "Special Status Plants" is a broad term used to refer to all the plant taxa inventoried by the Department of Fish and Game's Natural Diversity Data Base (NDDB), regardless of their legal or protection status. Special Plant taxa are species, subspecies, or varieties that fall into one or more of the following categories: • Officially listed by California or the Federal Government as Endangered, Threatened, or Rare; • A candidate for state or federal listing as Endangered, Threatened, or Rare; • Taxa which meet the criteria for listing, even if not currently included on any list, as described in Section 15380 of the CEQA Guidelines; • A Bureau of Land Management, U.S. Fish and Wildlife Service, or U.S. Forest Service Sensitive Species; • Taxa listed in the California Native Plant Societys Invcntory of Rare and Endangered Vascular Plants of California; • Taxa that are biologically rare, very restricted in distribution, or declining throughout their range but not currently threatened with extirpation; • Population(s) in Cali fornia that may be peripheral to the major portion of a taxon's range but are threatened with extirpation in California; and • Taxa closely associated with a habitat that is declining in California at an alarming rate (e.g., wetlands, riparian, old growth forests, desert aquatic systems, native grasslands, valley shrubland habitats, vernal pools, etc.). GOLDEN BEAR BIOSTtIDIES 19 8/24/04 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALUMA DEFINITION OF SENSITIVE PLANT COMMUNITIES Sensitive plant communities are those which are considered rare or have some regulatory aspect. All wetlands are considered sensitive because they are subject to federal regulation under Section 404 of the Clean Water Act. Blue -line streams are subject to additional regulation under Sections 1601-06 of the State Fish and Game Code. Rare plant communities are either of highly limited distribution or subject to threat. These communities may or may not contain rare or endangered species. The Department of Fish and Game's Natural Diversity DataBase's has incorporated a ranking system developed by the Nature Conservancy for vegetation types in California. The rankings assign rarity to communities according to their degree of vulnerability and imperilment. The ranking allows identification of plant communities that are most imperiled and, therefore, most in need of conservation attention. " FURTHER DISCUSSION OF THE REGULATORY CONTEXT U.S. Fish and Wildlife Service (USFWS) The USFWS has jurisdiction over species that are formally Iisted as threatened or endangered under the Federal Endangered Species Act (FESA). The Endangered Species Act provides broad protection for species of fish, wildlife and plants that are listed as threatened or endangered in the U.S. or elsewhere. Provisions are made for listing species, as well as for recovery plans and the designation of critical habitat for listed species. The Act outlines procedures for federal agencies to follow when talcing actions that may jeopardize listed species, and contains exceptions and exemptions. California Department of Fish and Game (CDFG) It is state policy to conserve, protect, restore and enhance any endangered or threatened species and its habitat. The CDFG has jurisdiction over species that are formally listed as threatened or endangered under the California Endangered, Species Act (CESA). The Endangered Species Act provides broad protection for species offish, wildlife and plants that are listed as threatened or endangered in the state. hi addition to CESA, the California Native Plant Protection Act (NPPA) provides protection to endangered and rare plant species, The CDFG also maintains an informal list of species of special concern to be considered during CEQA review. California Native Plant Society (CN -PS) CNPS is a non-profit group dedicated to preserving the state's native flora. It has developed lists of plants of special concern in California (Skimmer and Pavlik, 1994): List IA - Presumed Extinct in California, List 1B - Rare or Endangered in California and Elsewhere, List 2 - Rare and Endangered in California, More Common Elsewhere, List 3 - Species For Which More Information is Needed, List 4 - Plants of Limited Distribution (.A Watch List). Impacts to CLAPS List 113 and 2 plants are considered significant under CEQA. GOLDEN BEAR BIOSTUDIE$ 20 8124104 BIOLOGICAL ASSESSMENT: PINNACLE RIDGE PUD, PETALuNIA U. S. Army Corps of Engineers (USACE) Section 404 of the Clean Water Act requires approval prior to discharging dredged or fill material into the waters of the United States. Waters of the United States includes essentially all surface waters such as all navigable waters and their tributaries, all interstate waters and their tributaries, all wetlands adjacent to these waters, and all impoundments of these waters. "Wetlands" are areas characterized by growth of wetland vegetation (buh-ush, cattails, rushes, sedges and willows) where the soil is saturated during a portion of the growing season or the surface is flooded during some part of most years. Wetlands generally include swamps, marshes, bogs and similar areas. Regional Water Quality Control Board (RWQCB) Under Section 401 of the Clean Water Act, projects that apply for a Corps permit for discharge of dredge or fill material, and projects that qualify for a Nationwide Permit, must obtain water quality certification from the RWQCB that the project will uphold state water quality standards.

Your client is interested in developing the property, which could impact special -status bat species potentially roosting within the buildings and/or trees that occur on the site. Two California Special Concern bat species, pallid bat (Antrozous pallidus) and Townsend's big -eared bat (Corynorhinus townsendii), have potential to occur on the project (CDFG 2004, personal observations). In addition, four Federal Species of Concern bat species have the potential to occur on the site, roosting either in the available potential building or tree habitat. Several bat species with no special status also occur in the project vicinity (Tatarian, personal observations). As a result, a habitat assessment of the buildings, and a cursory assessment of the trees around the buildings, was conducted to identify potential roost habitat or observed bat roosting activity. Site Description The proposed project site is located on the west side of I Street, south of Grevilla Drive, and northwest of Kastania Road, in the southwest portion of Petaluma. The site occurs within the western portion of Section 10 of the Petaluma 7.5 -minute USGS topographic quadrangle, in the Township 4N and Range 7W area. It is bordered to the east, south and west by open space and ranchlands, and to the north by recent residential development. The site consists of rolling hills ranging from approximately 235 to 600 feet in elevation. Seven buildings occur on-site which will be demolished to accommodate proposed development of the site, including: 1) a single -story stucco ranch house, 2) a wood -sided water tank tower, 3) a wood -sided garage, 4) a small wood -sided shed, 5) a large metal -sided barn, 6) a large wood -sided horse barn, and 7) a wood - sided horse stable. The residence has been unoccupied for two years, and the remaining structures have been unused for a longer period (Weimeyer, personal communication). Several trees, primarily non-native ornamentals, occur in proximity to the residence, barn, garage and water tank tower. These include paper birch (Betula papyrifera), juniper (Junipers sp.), planted redwood Rockpointe Ridge Bat Habitat Assessment Page 1 of 10 Wildlife Research Associates (Sequoia senipervirens), and other ornamentals (Weimeyer, personal communication). Valley oak (Quercus lobata) and interior live oak (Quercus agrifolia) occur on the hillside above the fenced animal enclosures behind the large barn and garage. Bat Roosting Ecology There 25 known species of bats in California (CDFG 2000). Of those, 11 (44%) are classified as California Special Concern species (CDFG 2004a), six of which roost in buildings. Five of California's 25 bat species (20%) are most commonly found to use building roosts as day and/or night roosts; pallid bat, big brown bat (Eptesicus fuscus), Yuma myotis (Myotis yumanensis), Brazilian free -tailed bat (Tadarida brasiliensis), and little brown bat (Myotis luc fiigus). An additional eight of California's 25 species (32%) sometimes use buildings (Brown and Pierson 1996). The author has observed eight species using buildings (Tatarian, personal observations). Bats typically show strong site fidelity to permanent roost sites, both natural and anthropogenic, and maternity roost sites elicit very high site fidelity by bats (Irunz 1982). In general, bats are opportunistic in their selection of night roosts, which implies that site fidelity at these roosts would be low. However, recent studies (Lewis 1994, Pierson 1999, and ongoing radio telemetry studies by Tatarian) suggest that night roosts elicit high night -to -night and year-to-year site fidelity. Bats are sensitive, in varying degrees, to roost disturbance. While some species like Townsend's big -eared bat exhibit preferences for abandoned structures, many species readily adapt to structures used and occupied by people, such as those found on this site. Because of this high site fidelity behavior by bats, signs of usage are often well established. Typical signs of presence of roosting bats in buildings include urine staining on exterior landing surfaces, fecal pellet accumulation, and characteristic odor. These signs are also usually present to varying degrees in natural roost sites such as trees, rocks and caves. Use of buildings by bats varies by season, region, and species, and other factors. Bats may roost in a structure only for breeding, ie. February through August, or may use a structure year-round — overwintering in torpor (a light form of hibernation), becoming active perhaps only once every few weeks. Some species will overwinter in structures from about October through January or February, but not be present during breeding months. Bats dispersing from summer colonies will sometimes exhibit this behavior as well. This variability makes it risky to assume bats are absent during winter months, even when summer survey results are negative. However, not all buildings available to bats provide suitable roost habitat, as the buildings may not provide appropriate temperature, humidity and other requirements for bats; such factors vary by species. Also, the level of disturbance created by human or other activities can exceed the tolerance of many bat species, or populations. In addition, most bats cannot enter through openings smaller than 3/8" x %" (Tatarian, personal observations), so if suitable entry points are not available, the building will not provide interior roosting habitat. Trees provide roost sites, either day or night, for many bat species. Four bat species are obligate tree - roosting species, roosting singly in bark crevices, cavities, or in the foliage. Trees are important roosts to another 11 species; many colonial bat species also use trees that possess suitable features, such as crevices formed by exfoliating bark or bark fissures. Other colonial bat species will use cavities in trees formed by fire, lightning, or other wildlife species. Trees with large cavities can support fairly large numbers of bats (100-300), while others may provide habitat for one male, or one female and her pups. Because of this roosting ecology, those trees most often considered undesirable or hazardous by humans - large dying or dead trees (snags) - are most attractive to bat species, though use of trees by bats is not limited to those types 26721 Street, Petaluma Bat Habitat Assessment Page 2 of 10 Wildlife Research Associates of trees. Roost habitat selection by bats in forests is variable temporally; bats switch tree roosts frequently, but overall site fidelity over time is high (Barclay and Brigham 1996). Lasiurine bats, such as the western red bat (Lasiurus blossevillii) and the western yellow bat (I asiurits xmtthirurs), are primarily obligate tree -roosting species, and for the most part, do not form colonies, but roost singly in foliage (others roost under baric or in cavities), The western red bat is found in lower elevations, primarily in riparian and wooded habitats, roosting in the foliage of broad -leafed trees. Though the species is not currently a California Special Concern species (CSC), as designated by the California Department of Fish and Game (CDFG, 2002a), the Western Bat Working Group (WBWG) (1998) classifies it as a High Priority species in the region. As such, increasing attention is being paid to loss of suitable riparian habitat where this species occurs. Bat species commonly associated with caves, rocks, and analogs to these natural roosts — mines, buildings, bridges, etc. — will also use trees for day and night roosting activity. The potential for negative impact to these bats when removing individual trees is greater than for foliage -roosting bats, because of the potential for larger numbers of bats to occur in the tree cavity. One such species is the pallid bat, a California Special Concern species, and a WBWG High Priority species. The pallid bat is found in a variety of habitats, from desert to coniferous forests and non -coniferous woodlands. In California, the species is strongly associated with oaks, and roosts in tree hollows, rock crevices, mines, caves, buildings and bridges. Typical colony size ranges from 30-70 individuals, though larger colonies over 300 are known. Regulatory Background Bats are classified as non -game mammals by the California Department of Fish and Game. Of the 25 known bat species in California, 11 are classified as California Special Concern species (CSC), and nine (including subspecies) are Federal Species of Concern (FSC), Bats are afforded protection under various Fish and Game Code sections, including Sections 86, 2000, 2014, 3007, and 4150. Several sections under Title 14 of the California Code of Regulations also apply, including but not limited to; Section 251. 1, Article 20, Section 15380, Section 15382, and several sections under the California Public Resources Code, Division 13. Methods A habitat assessment was conducted by on July 14, 2004, by Greg Tatarian. All structures were examined for evidence of bat roosting activity, as shown by openings suitable for entry by bats, accumulations of fecal pellets, urine streaking, or staining of exterior wall and window surfaces. The trees surrounding the structures were evaluated for potential tree roost habitat. Emergence surveys were not conducted as part of this effort. Results None of the structures showed past or present evidence of either day or night roosting activity by bats. No staining, fecal pellets, live or dead bats, or characteristic odor of bat urine was observed in or around any of the structures. The residence, a single -story stucco -sided building, contained only two potential openings for bats into the structure — the two attic gable vents. These had been covered with window screen mesh at some time in the past, and appeared mostly intact. No other openings were observed around the caves, walls or roof overhangs. An inspection of the attic area showed no evidence of past or present use by bats. Large numbers of rat (Rattus sp.) fecal matter was found in the attic and in some of the interior rooms of the residence. Rockpointe Ridge Bat Habitat Assessment Page 3 of 10 Wildlife Research Associates The water tank tower, constructed of wood, contained numerous openings around the eaves, doors and walls that are suitable for entry by bats. Despite this, no evidence of bat activity was observed, however large numbers of rat and tree squirrel, presumably Western gray (Sclurus griseus), fecal pellets were observed in the upper and lower floor areas. The corrugated metal -sheathed wood frame garage, and wooden large barn and small shed structures, all contained numerous openings suitable for bats. No evidence of bat activity was observed, although rat and mouse, presumably house mouse (Mus musculus), fecal matter was present. Relatively fresh regurgitated prey pellets from barn owls (Tyco alba) were observed in the large barn. No barn owls were observed in any of the structures. The large barn and small shed -roof horse barn, located to the south of the residence, each contained numerous openings suitable for bats, at walls, doors, and eaves. Additionally, the large bans had suffered a fire in the past, leaving an approximately 4' x 40' section of the roof open through the rafters. No evidence of bat activity was observed. None of the trees surrounding the buildings appeared to contain cavities suitable for roosting by bats. The oaks on the hill behind the buildings did not appear to contain suitable openings, but because of the density of canopy and undergrowth, itis possible that some cavities exist but were not observed. Discussion The age, construction and condition of the structures all provide elements that bats find suitable for day and/or night roosting activity. Despite this, none of the structures showed evidence of past or present use by bats. Except for the attic of the residence and the garage, the buildings were too open to provide suitable day -roosting habitat for bats. The garage is actively used for storage of mowers and equipment, and the building has a low ceiling height, making it less suitable as a day roost. In addition, extensive prior barn owl use of the large barn was observed. Though barn owls and bats have been observed nesting and roosting together, predation by barn owls appears to be a factor in reducing or eliminating bat roosting populations from such structures (Tatarian, personal observations). Although no specific tree roosts were observed, it is possible that potentially suitable roost cavities occur in the oaks on the bill behind the buildings. If development of the site will occur within 50 feet of the trees, loss of potential tree -roost habitat for several bat species, including colonial, and solitary, obligate tree - roosting bats could occur. Because tree -roosting bats move frequently among roost trees, surveys showing absence from a suitable roost cavity have limited temporal validity. Also, because bats roosting in bark crevices are very hard to detect, results of focused surveys to determine presence or absence of bats from tree roosts should be interpreted cautiously. Other methods to reduce or eliminate impacts (such as seasonal tree removal or trimming, staged removal of limbs and trunk, and removal of adjacent trees not providing habitat prior to those with suitable roost characteristics) should be combined with identification of suitable roost characteristics, which will require a tree roost habitat assessment. Recommendations A) The window screen mesh covering the gable vents of the residence is mostly intact, but should be maintained, or the gable vents sealed with plywood, until the building is demolished. The residence should be demolished within 30 days of this survey. After that time, it is possible that bats could begin to day roost in the building. B) If demolition of the residence can not occur within 30 days of this survey, then the building shall be surveyed by a qualified bat biologist possessing a Memorandum of Understanding with the California Department of Fish and Game, no more than 2 weeks before demolition, to avoid 2672 1 Street, Petaluma Bat Habitat Assessment Page 4 of 10 Wildlife Research Associates "take" of any bats that may have begun to use the structures for day -roosting subsequent to this assessment. It is recommended that demolition take place between now and Oct. 15, 2004, in order to avoid project delays caused by bats that may have begun to roost in the structure(s) during the fall (they may become seasonally torpid, which would delay humane eviction until mid-February, 2005). C) No trees or limbs of the oak trees described in this report shall be removed without fust having a qualified bat biologist conduct emergence surveys to determine presence or absence of day roosting bats. No machinery shall be parked or used beneath the trees, to prevent fumes and noise from impacting bats that may be roosting inside tree cavities.

The site is 15.56 acres and located at 2762 I Street, Petaluma, California (APN# 019-401-019). This report is intended to supplement Golden Bear Biostudies, Biolop-ical Assessment, Snecial. Status Species and Habitat Survev of the Pinnacle Ridge PUD Proiect. Petaluma, dated August 24, 2004. The Biological Assessment recommended that special status plant species surveys be conducted in early and mid -spring of 2005 because special status plant species surveys were not conducted in early spring of 2004. No special status plant species were observed at the site during the field surveys conducted by Darren Wiemeyer, Staff Ecologist, on April 20 and May 11, 2005. In addition, no special status plant species were observed during the field surveys conducted on June 28 and August 7, 2004. These four field surveys adequately cover an entire floral season. Based on the results of these surveys, the Pinnacle Ridge PUD project will not disturb or impact any special status plant species. General Site Description and Project Description The Pinnacle Ridge PUD project site is located at 2762 I Street, Petaluma, California (Figure 1). The Assessor's Parcel Number is 019-401-019. The site is situated in the foothill area on the southern end of Petaluma. The project site is approximately 15.56 -acres in size and ranges from 140 to 330 feet in elevation. The area surrounding the project site is mostly undeveloped 406 E.

The majority of the site consists of open grassland that has been used as grazing lands up until the recent past There are seven building on site. They include a single -story stucco ranch house, a wood -sided water tank tower, a wood -sided garage, a small wood -sided shed, a large barn, a large wood -sided horse barn, and a wood -sided horse stable. Eleven single-family homes will be built and a cul-de-sac road will be constructed to access these homes. A 5.91 acre area at the southern end of the site will be preserved within an urban separator. Literature Review Information on the biology, distribution, taxonomy, legal status, and other aspects of the special -status species was obtained from documents on file in the library of Golden Bear Biostudies. Standard references used for the biology and taxonomy of plants included Hickman, ed., 1993 and Best et al, 1996. Existing literature was reviewed for information regarding sensitive resources that have the potential to occur in the project area (Waaland,1989; Patterson et al, 1994; CH2M Hill et a1,1995). The CDFG California Natural Diversity Data Base (CNDDB) was queried for a list of all plant and animal species reported from the Petaluma, Cotati, Glen Ellen, Point Reyes NE, Inverness, Two Rock Petaluma River, Sara Geroninao, and Novato USGS 7.5 -minute quadrangles (nine quad search). The Electronic inventory of Rare and Endangered Vascular Plants of California (CNPS, 2001) was queried for a list of all plant species reported from the Petaluma, Cotati, Glen Ellen, Point Reyes NE, Inverness, 71vo Rock Petaluma River, San Geronimo, and Novato USGS 7.5 -minute quadrangles. The following table (Table 1) is a list of special status plant species that have the potential to occur at the site based on observed habitat types.

Rare and Endangered in California, More Common Elsewhere GOLDEN BEAR BIOSTUDIES ® Page 6 July 14, 2005 Methods Special status plant species surveys were conducted on April 20 and May 11, 2005. They were conducted in a manner to identify any rare or endangered species that may be present during the spring and summer blooming period (CDFQ 2000; USFWS, 1996). Surveys were conducted when most rare or endangered species that could occur in habitats at the site would be both "evident" and "identifiable". The surveys were floristic in nature and not based on the occurrence of habitat or other physical features. The survey was conducted using systematic field techniques in all habitats of the site to ensure a reasonably thorough coverage of potential impact areas. A meandering pattern was walked through each habitat to ensure that all areas were viewed. All plants at the site were identified to the level necessary to ascertain whether they were "special status species". Results No special status plant species were observed during the surveys. The site lacked appropriate habitats for virtually all of the special status species listed in Table 1. The absence of specialized habitats, such as serpentine soils, vernal pools, or salt marshes, greatly restricts the possibility of finding rare and endangered species in the disturbed grazing land. The history of grazing and the spread of exotic, weedy species results in the replacement of the native flora on sites like the project site, as it has throughout California. Based on the results of these surveys, including the surveys conducted in 2004, the Pinnacle Ridge PUD project will not disturb or impact any special status plant species.

The USACE jurisdictional wetland map was an attachment to a January 6, 2005 jurisdictional letter regarding the subject site (copy of map and letter is attached). The USACE only exerted jurisdiction on the drainage channel (seasonal wetland swale) located within the urban separator at the southwest corner of the site. Bryan Matsumoto with the USACE included a solid line on the jurisdictional wetland map to identify the roadside drainage ditch so it would not be confused with the study area boundary or the jurisdictional drainage channel (seasonal swale). However, I had already identified the roadside drainage ditch on the map with a modified dashed line. The other larger dashed lines that are visible on the jurisdictional wetland map are from the AutoCAD base map which outlines the existing residential parcel. Attached, as Figure 4, is a plant communities map which shows this larger dashed line. I have placed a solid blue line next to it so it is clearly visible. This larger dashed line in no way should be interpreted as a USACE jurisdictional feature. The USACE did not claim jurisdiction on the roadside drainage ditch because the roadside drainage ditch did not exhibit wetland characteristics and because it is not a natural drainage or waterway. Therefore, the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) and California Department of Fish and Game (CDFG) would not have jurisdiction on these features. Filling of the roadside drainage ditch would not reu e permittingthrough the USACE, SFBRWQCB, or CDFG. (..rF- t /'C:7 r-, 400 E.

Craig Lawson Pinnacle Homes 131 Stony Circle Santa Rosa, California 95401 Dear Nor. Lawson: JAN Q 6 20'5 Thank you for your submittal of September 8, 2004 requesting confirmation of the extent of Corps of Engineers jurisdiction at the Pinnacle Ridge PUD project site located at 2762 I Street in the City of Petaluma, Sonoma County, California (APN 019-401-019). Enclosed is a map showing the extent and location of Corps of Engineers jurisdiction December 17, 2004. We have based this jurisdictional delineation on the current conditions of the site. A change in those conditions may also change the extent of our jurisdiction. This jurisdictional delineation will expire in five years from the date of this letter. However, if there has been a change in circumstances that affects the extent of Corps jurisdiction, a revision may be done before that date. All proposed discharges of dredged or fill material into waters of the United States must be authorized by the Corps of Engineers pursuant to Section 404 of the Clean Water Act (CWA) (33 U.S.C. Section 1344). Waters of the United States generally include tidal waters, lakes, ponds, rivers, streams (including intermittent streams), and wetlands. Your proposed work may be within our jurisdiction and a permit may be required. Application for Corps authorization should be made to this office using the application form in the enclosed pamphlet. To avoid delays it is essential that you enter the file number at the top of this letter into Item No. 1. The application must include plans showing the Iocation, extent and character of the proposed activity, prepared in accordance with the requirements contained in this pamphlet. You should note, in planning your work, that upon receipt of a properly completed application and plans, it may be necessary to advertise the proposed work by issuing a public notice for a period of 30 days. If an individual permit is required, it will be necessary for you to demonstrate to the Corps that your proposed fill is necessary because there are no practicable alternatives, as outlined in the U.S. Environmental Protection Agency's Section 404(b)(1) Guidelines. A copy is enclosed to aid you in preparation of this alternative analysis. -2 - However, our nationwide or regional permits have already authorized certain activities provided specified conditions are met. Your completed application will enable us to determine whether your activity is already authorized. You are advised to refrain from commencement of your proposed activity until a determination has been made that an existing permit covers it. Commencement of work before you received our notification may be interpreted as a violation of our regulations. You are advised that the Corps has established an Administrative Appeal Process, as described in 33 C.F.R. Part 331 (65 Fed. Reg. 16,486; Mar. 28, 2000), and outlined in the enclosed flowchart and "Notification of Administrative Appeal Options, Process, and Request for Appeal' form (NAO-RFA). If you do not intend to accept the approved jurisdictional determination, you may elect to provide new information to the District Engineer for reconsideration or submit a completed NAO-RFA form to the Division Engineer to initiate the appeal process. You will relinquish all rights to appeal, unless the Corps receives new information or a completed NAO-RFA form within sixty (60) days of the date of the NAO-RFA.

This analysis addresses the potential impact the project would have on surrounding streets in the area. The proposed project includes eleven detached single-family units with a single access onto 1 Street Existing Conditions The study area consists of I Street adjacent to the project site. I Street has two lanes with sidewalk, curb and gutter on the northerly side of the street Currently I Street carries approximately 3,000 vehicles per day. The General Plan Kladopted Level of Service (LOS) standard for streets indicates the minimum acceptable operation is LOS C where it is currently LOS C or better. Where operation was at LOS D or E in 1985, it shall not deteriorate to the next lower level. Under a City Council Policy adopted in 1990, mitigation is required at any study intersection where the project results in delay worse than LOS D. Currently the portion of I street adjacent to the project site operates at LOS A during the p.m. peak hour. Project Trip Generation and Distribution For purposes of estimating the number of vehicle trips that the proposed use would be expected to generate, Trip Generation, 7' Edition, 2003 by the Institute of Transportation Engineers (ITE) was used. This publication is a standard reference used by jurisdictions throughout the country, and is based on actual trip generation studies performed at numerous locations in areas of various populations. For this project, the Single Family Detached Housing category (Land Use #210) was used to project vehicle trips. The proposed Pinnacle Ridge subdivision project is expected to generate an average of 105 daily trips, including 8 trips during the a.m. peak hour, and I I during the p.m. peak hour. Trip generation estimates for the project are summarized in Table I. RECEIVED E NOV 66 2008 COMMUNITY DEVELOPMENT DEPARTMENT Mr. Steve LaFranchi Page 2 June 6, 2005 Table I Trip Generation Summary for Proposed Use Land Use Size Daily I A.M. Peak HourP.M. Peak Hour Rate Trips Rate Trips In Out Rate Trips In Out Single Family Residential I I sfd ( 9.57 145 10.75 8 2 6 11.01 11 Trip distribution characteristics were determined by examining existing patterns of traffic and the locations of services and schools in the project area. It was assumed that approximately 90 percent of traffic originating from the proposed Pinnacle Ridge subdivision would be oriented to the north an D Street, with the remaining 10 percent oriented to the east an Sunnyslope Avenue. Existing plus Project Conditions Upon the addition of project -generated traffic, I Street is expected to continue operating acceptably at LOS A during p.m. peak hour with a volume -to -capacity ratio increase to 0.17 from 0. 16, an increase of OA I. The project will have a minor incremental impact with service levels remaining at LOS A.. Site Access Access to the project would be provided via a new street connection to I Street It is expected that the proposed street connection would provide adequate access to the surrounding street network. Sight distances were evaluated from the proposed access based on sight distance criteria contained in the Caltrans Highway Design Manual, 5' Edition. The Highway Design Manual provides stopping sight distance criteria that are typically applied to driveways. The speed limit on I Street is posted at 35 mph. For an approach speed of 35 mph, the minimum stopping sight distance needed is 385 feet To the southeast along I Street the least sight distance measured was 450 feet due to the crest of a hill. To the northwest the sight distance is over 1,000 feet. Since more than 385 feet of stopping sight distance is available in both directions from the project access, the sight distance is adequate. Future Conditions The City of Petaluma has developed a Traffic Model for use in evaluating the potential traffic impacts of buildout of the land uses described in the current General Plan together with new or improved streets. The model is an electronic simulation of streets and roads, called links, and sub areas of the City, called Traffic Analysis Zones (TAZ). The links represent the street system and have values indicating capacity, travel speed, distance and lanes while TAZlslhave values for various land use categories such as housing, commercial and industrial uses. The model uses an iterative process to assign trips originating in one zone to likely destination zones based upon home -to -work shopping and work related trips. The accumulation of trips from each zone provides the anticipated traffic demand for each link in the system. The Pinnacle Ridge Subdivision site is located within TAZ 117 of the City DTraffic Model, The General Plan assumptions for TAZ 117 include an additional I I single family dwellings from year 2002 baseline conditions. The Pinnacle Ridge Subdivision at I I single family homes will meet the anticipated development potential of TAZ 117 and the trips from this project have been considered within the General Plan Update. Mr. Steve LaFranchi Page 3 June b, 2005 Conclusions ❑ The project will add an average of 105 daily trips to the area circulation system, including 8 a.m. peak hour trips and I I p.m. peak hour trips. ❑ The service level on 1 Street will remain at LOS A with project added traffic volumes. ❑ The added traffic volumes have been foreseen and are included in the City of PetalumaRlGeneral Plan Traffic Model. ❑ The project access design will need to maintain a minimum of 385 feet of sight distance in both directions along I Street. The final improvement plans will need to incorporate landscaping and site grading that will maintain the required sight distance. Please call me if you have any questions regarding this information.

Project 04-040 INTRODUCTION As requested and authorized by Craig Lawson of Pinnacle Homes, Archaeological Resource Service has conducted an archaeological evaluation of the parcel described below. Tho evaluation consisted of four separate aspects: 1. A check of the information on file with our office and the Northwest Information Center of the California Historical Resources Information System, to determine the presence or absence of previously recorded historic or prehistoric cultural resources within or adjacent to the project area; 2. A check of appropriate historic references to determine the potential for historic era archaeological deposits, or features, such as standing structures greater than 45 years of age, to be located within the project area: 3. An evaluation of the standing structures on the property to determine if they have historic importance; and 4. A surface reconnaissance of all accessible parts of the project area to locate any visible signs of potentially significant historic or prehistoric culturat deposits, features or isolated artifacts that would be adversely impacted by the proposed project.

Approximately 5,9 acres on the southern side of the parcel will be left undeveloped as an urbar separator. PROJECT LOCATION The project area is located at 2762 "1" Street, just outside the city limits of Petaluma, The Assessor's parcel number is 019-401-019. The property consists of approximately 15 acres of open land with one house with an associated garage, barn, stable and sheds located on the northeast edge of the property. The property is bounded by single-family homes that are part of the Westridge Knolls subdivision on the north, "I" Street on the east, and undeveloped grassland on the south, and west. The project area lies in the western half of the northwest quarter of Section 10 of Township 4 North Range 7 West, Mt. Diablo Base and Meridian. The Universal Transverse Mercator Grid coordinates to the approximate center of the project area, as determined by measurement from the Petaluma California USGS 7.5' Quadrangle Map 1953 (photorevised 1980) and the Petaluma River USGS 7.5' Quadrangle Map 1953 (photorevised 1980) are: 4228840 Meters North, 532800 Meters East, Zone 10 FIGURE 2. PROJECT LOCATION SHOWN ON POFTIONS OF THE PETALUMA AND PETALUMA RIVER 7.5' QUA 1DRANGLE RESULTS OF LITERATURE MAPS. CHECK PREHISTORIC BACKGROUND In the early years of the twentieth century an ethnographer named S.A. Barrett traveled around Ithe greater Sonoma County region to record the linguistic boundaries of native groups and the locations of lboth active and old village sites (Barrett 1908). The property is'located in what was the territory of the C ast Mlwok. The Coast Miwok territory roughly consisted of what is today Marin County and Southern Sonoma County. The closest village location Barrett recorded to the current project area was a Coast Miwok pl ce named wotoki (Barrett 1908). The site was described as an old village site "on the west bank of Petalpma Creek probably near what is known as Donahue's landing at a point about three miles and a half southeast of Petaluma" (Barrett 1908:310). This site is located over a mile to the east of the current prl jest area. Habitation sites in Sonoma County and the Coast Miwok territory are marked by midden soil, the result of broken down organic material that is very dark In color and friable in texture. These cultural s )its usually contain the remains of shellfish, fish and animal bones, debris from the making of chipped Ston a tools and the tools themselves, and ground stone tools. Shell, stone and bone jewelry and implemen s are also found.

Additionally, several rock outcrops in the region with Native American modification have been recorded by archaeologists (King 1965; Miller and Haslam 1974; Miller [1977). HISTORIC BACKGROUND In 1877 the project area was a portion of 80 acres belonging to William F. Bowman, Bowman's residence was located on the east side of "I" Street, off of the current project area, and no structures are shown to have been located on the current project area. In 1897 the Bowman property had been subdivided and the project area was a portion of 20 acres belonging to M.S. Parker, no structures are detailed cn the map. However, the 1914 USGS quadrangle map shows a house located on the property. Sederal more structures, likely the barns, are shown to have been added between 1953 and 1980. Consequently the house was built at sometime before 1914, and outbuildings were added between 1953 and 198). PREVIOUS STUDIES IN THE AREA Prior to undertaking a field survey, the archaeological base maps, reports and historical documents located at the Northwest Information Center of the California Historic Resources Informat'nn System (CHRIS) and on file with Archaeological Resource Service pertaining to this area of Pet ]Lima were consulted. It was determined that the project area has not been previously studied for cultural resources. However, archaeologists have previously evaluated several parcels in the vicinity. At Ii ast twelve evaluations for cultural resources have been conducted within a mile of the current projec , While six archaeological sites and five historic buildings have been recorded (Allison and Jordan 1991; E eard 1998; Chattan 1999; Flynn 1998; Hayes and Fredrickson 1981; Haney 1983; King 1965; Orlins 197 ; Stradford and Fredrickson 1977), the majority of these studies have not encountered any evidence of p ahistoric or historic use of the area (Beard 2000; Hayes 1978; Jackson 1977; King 1987; Origer 1991; Quinn and Origer 1989; Roop 1990). Additionally there are quite a few archaeological sites to the northwest just over a miles distance from the current project area. The closest recorded archaeological site to the current project is known as CA-Sor-402. The Northwestern California Archaeological Society originally recorded CA -Son -402 In 1962, and returned for a test excavation in 1963. Some of the artifacts recovered during their excavation include mortar and pestle fragments, obsidian and chert tools and clamshell disc beads. CA -Son -402 was then ree,lcountered during a survey in 1977 that included the property immediately to the west of the current projgct area. At that time, the site was described as a gray ashy midden soil with obsidian and chert flas, charred mammal bone, marine shellfish and fire fractured vesicular basalt (Stradford and Fredrick on 1977). During the 1977 survey, a historic bam was recorded on the same property (CA -Son -1035H). Subsequent construction in the vicinity of the prehistoric archaeological site was monitored by archaeologilsts (Allison and Jordan 1991), Also in 1977, 2.5 linear mlles along D Street were surveyed as part of a proposed extension of the street (Orlin 1977). During the survey, three prehistoric sites were recorded and assigned they numerical designations of CA -Son -1082, CA -San -1083 and CA -Son -1084. CA -San -1082 was recorded `as a "large well-developed midden along [the] road and under residence and grounds. [With] many a6ifacts and cultural constituents" (Orlins 1977b). Artifacts observed within the site included small obsldiah excelsior points and corner notched points, a reworked point fragment, obsidian and chert tools and flaking waste, a hammerstone, a quartz flake, vesicular basalt chunks, fire cracked rock and glass and ceramIq fragments (Orlins 1977b). The site was further examined in 1978 and 1981 (Hayes and Fredrickson 1981; Adams 1978). This site is located at a half -mile distance from the current project. CA -Son -1083 was rgcorded as a possible midden deposit with basalt flakes and flaking waste (Orlins 1977c), This site is locat6d at a mile distance from the current project. CA -Son -1084 was noted as a quarry site with "chert flakes E nd chunks scattered around boulders and outcrop. Small areas of dark soil may be midden" (Orlins 1977c). This site is located one and a half miles from the current project. In 1989, an archaeological field study of the lengths of Sunnyslope Avenue and Sunnyslope Road was completed by the Department of Anthropology at Sonoma State University (Quinn and Oner 1989). Although no artifacts or sites were encountered during the project, the report notes that sites C,A-Son 402 and CA -Son -1082 are located nearby the assessment district, and that "the location of the proj�ct area at the base of foothills, the presence of the two water courses, the artifacts discovered in t e past fill 05/27/2004 15:16 17677621791 ARS PAGE 05 I A Cultural Resources E aluation of the Property Located at2702'r Street (APN 019-401-019), Petaluma, Sonoma Co nty, California May, 2004 transport, and the past finds at other nearby locations, indicate that the project area malybe a likely location for additional cultural resource site discoveries." Additionally prehistoric artifacts were discovered in soil at the McNear School property (CA -Son -1326). However, these artifacts were deterined to be located within fill soils transported from a property on Petaluma Boulevard North (Quinn and tiger 1989; 197). In May of 1998, Vicki Beard evaluated the structures on a property on Sunnyslope Road for historic potential. A barn and house on that property were identified as a turn of the century historic Farm/ranch, and a site record was filed with the CHRIS (P-49-002551). Although the structures were of significant age, it was determined that the buildings did not meet the requirements for the National Register of Historic Places (Beard 1998). Archaeological Resource Service evaluated the same parcel the follow ng year for the potential of archaeological materials to be located on the property. No evidence of artifacts or subsurface deposits were observed (Chattan 1999). In an evaluation of approximately ten acres located to the northeast along Sunnyslope Road the author encountered several historic era features, A house built between the late 1910s and the 19>40s with an associated barn, a shed, two spring boxes and two trash scatters was recorded. The first trash scatter consisted mostly of crushed tin cans and clear and amber colored bottle fragments. This scatter appears to be from the 1940s and 1950s. It covers an area roughly 20 feet wide by 30 feet long. A second trash deposit contained mostly metal objects such as fencing materials, baling wire, pipes, and fuel Oans, a few squashed tin cans and clear and amber colored glass bottle fragments. The trash appears to 1pe from the 1950s to modern times. These trash scatters consisted mostly of non-diagnostic Corrdad metal fragments and cans, and do not have the potential to yield important information about the p st (Chattan 2004a). The property was assigned the archaeological numerical designation of P-49-00306 (Chattan 2004b). The "Culver site" given the numerical designation of Son -450 is located about one half of a mil to the east and along a seasonal drainage. The site was described as a low ash midden with a concentration of obsidian flakes (King 1965). An outlying feature associated with this site was observed 'n 1998 by Katherine Flynn while conducting a survey on a neighboring parcel. This consisted of a midden deposit with shell and obsidian flakes and a bedrock outcrop within the creek containing three sr� all mortar depressions. A charmstone was also found in the creek (Flynn 1998). To the northeast of the project, in more rugged terrain near to the Petaluma River there are se6ral areas prehistoric use such as habitation sites, milling stations, and schist outcrops with petroglyphsi as well as historic quarries. i Sites such as Son -392 described as a midden deposit with several associated basalt outcrops that exhibit ground and pecked depressions including bedrock mortars, metate surfaces and cupule petrog'yphs (King 1958); Son -844, a group of six chlorite schist boulders over a 100 -yard area, with pecked circles and ovals (Miller and Haslam 1974; Cole 1980); Son -846, Son -847 and Son -848, petroglyphs on schidyt boulders, similar to Son -844 (Miller and Haslam 1975b; Roybal 19948); and Son -2152 "an area with a high concentration of burnt rock fragments, obsidian flakes, shell fragments, and dark friable sail" (Roybal 1994a: 4). Historic complexes in the area include an 1860's house and several outbuildings from the 1 B80's were noted as located on the property, but these were not recorded as historic structures at the time. This complex has subsequently been determined to be of historic importance (CalTrans 1999). Rasmussen / Brians ranch a Victorian farmhouse, several associated outbuildings and a scatter of broke ceramics (Haney 1983). The site was given the numerical designation of Son -1412H. There were a so several historic era quarries located in the hills just west of Haystack Landing. This includes quarne known as Mae Hill, Mt. Pisgah, Petaluma Rock Company, Classen Quarry, Hein Brothers Basalt Rock Company, Cronin Quarry (Tuomey 1925; Tharp 1978; Chattan 2003c). Additional archaeological evaluations have been performed within a mile of the current prop rty, but no further archaeological sites have been encountered. The previously recorded sites in the arga are at a significant distance from the current project area and will not be affected by any improvem nts to the property. i 05/27/2004 15:15 17077621791 ARS PAGE 05 A Cultural Resources Evaluation of the Property Located at 2762 T Street (APN 019-401-019), Petaluma, Sonoma Coi inty, California May,2004 Prehistoric habitation sites in the area, as we have seen from the above examples, tend to b marked by midden soil, which is dark in color and contains chipped and ground stone tools or evlde ice of their manufacture. Quarry sites have been located around rock outcrops of siliceous materials, and rock outcrops of basalt may have been used for grinding of plant materials, leaving behind mortar c epressions. Additionally, petroglyphs in the Petaluma area were often placed on the vertical surface of s& ist outcrops and are characterized by the carvings of cupules or pecked curvilinear nuclei (Miller 1977). 1 RESULTS OF SURFACE EXAMINATION On May 18, 2004, Cassandra Chattan and Kristel Daunell of Archaeological Resource Service went to the property and { F. performed a surface reconnaissance and evaluated the structures for historic significance. The property Is relatively flat in the northeast portion of the property where the structures are, and there are steep hills in the rest of ,= the property. There is a small, seasonal drainage that passes through the southwestern tip of the property. The property was covered with very dense grasses that lie flat, obscuring the soil. These were pushed aside with a trowel in areas to observe the underlying soil, but for the most part visibility was very poor. The perimeter of the property was FIGURE 3. STRUCTURES, VIEWED FROM THE ENTRYW Y IN THE walked, and the rest of the NORTHEAST CORNER OF THE PROPERTY. property was transversed back and forth from east to west. Areas near the drainages and fla: and gently rolling areas were closely inspected. The steep areas were more difficult to examine, but aro unlikely to contain archaeological sites, and will not be built upon, There are several boulders or small rok outcrops in the southwestern portion of the property. These were each checked for evidence o prehistoric modification such as ground depressions or quarrying activities. The rocks were all c mposed of Franciscan melange, which is not typically used for mortar depressions or petroglyphs. No cultural modifications to the rocks were observed, and no evidence of prehistoric use was seen on the *perty. The property contains one house, a barn, a barn / garage, a shed/ garage, a water tower, a table and a shed. There are also three metal feed racks with shed roofs. The house is a stucco sided bu galow, with a front gabled roof, built in the 1900s or early 1910s. The structure is very plain on the exterio with some Craftsman stylistic elements, such as an arched entry porch with stucco porch supports. The front porch has been enclosed, Into two small rooms. The windows are double hung undivided pane winc ows. There is a carport attached to the rear (west) and a plain stucco sided addition on the north side. Tie house is roughly 20 feet wide by 30 feet deep and has a 15 feet wide by 10 feet deep addition. The barr has a front gabled roof with a shed addition on the west side. It is clad with vertically placed boards of var ling widths. The barn is roughly 25 feet wide by 25 feet deep. The garage / barn Is a very basic front gabl,:d structure with a front hanging door and no other doors or windows. There is a small shed roof addition on the rear (west side). This structure is sided with horizontally placed boards, that are approximately 6 riches wide and the same size and style used on the shed / garage and the water tower. The shed / ga age is clad with sheets of corrugated metal on three sides and horizontal clapboards on the east side whe ,e there are hanging doors on rollers. The water tower is approximately 8 feet wide and 8 feet deep and a i estimated 05/27/2004 15:16 17077621791 ARS PAGE 07 ! A Cultural Resources Evaluation of the Property Located at 27621' Street (APN 019-401-019), Petaluma, Sonoma County, Califomia May,2004 i sixteen feet tall with a flat roof. It is clad with horizontal boards. All the out buildings are in somewhat poor condition, with boards and doors failing off. The complex was a typical small farm, having a small house and several associated outbuildings and pastureland. However, the complex is not in good condition, nor is it an exceptional example o this type of property. The house is not a good example of a Craftsman style residence, and it is not withi an existing or potential historic district. Because it is likely to be removed as part of the development of tho parcel, the complex will be recorded on a DPR 523 form to document the previous use of this area. No significant historical resources are recorded on or immediately adjacent to the current project area CONCLUSIONS AND RECOMMENDATIONS No evidence of prehistoric activity was observed on the property. While high grasses o scured soil visibility, the surveyors pushed these aside with a trowel to observe the soil in test areas thr ughout the parcel. While isolated artifacts may have been obscured from view, it is unlikely that an archae logical site would have been missed. The south half of the parcel Is relatively steep and would have baeltiunsuitable for prehistoric habitation. The structures in the northwest corner of the property compose a small farming complex. Wile none of the structures individually are of note, the concentration is typical of small farms in the area�and will be recorded because It is planned to be removed. While the complex is typical of small farms iifi the region there is no attribute that would make it eligible for the National Register of Historic Places or the California Register of Historic Places. While archaeological monitoring Is not warranted at this time, in the event that a concentratldn of artifact or culturally modified soil deposits including additional trash pits older than fifty years bf age, are discovered at any time during grading, scraping or excavation within the property, all work should be halted In the vicinity of the find and a qualified archaeologist should be contacted immediatelylto make an evaluation. If warranted by the discovery of a concentration of artifacts or soil deposits, furthei work in the discovery area should be monitored by an archaeologist. I Artifacts that are typically found associated with prehistoric sites include humanly modified stone, shell, bone or other cultural materials such as charcoal, ash and burned rock Indicative of food pro urement or processing activities. Prehistoric domestic features include hearths, firepits, or house Floor depressions whereas typical mortuary features are represented by human skeletal remains. Historic artifacts potentially include all by-products of human land use greater than 50 years of age. Although highly unlikely, if human remains are encountered, all work must stop in the immedia�e vicinity of the discovered remains and the County Coroner and a qualified archaeologist must ,be notified immediately so that an evaluation can be performed. If the remains are deemed to be Native American and prehistoric, the Native American Heritage Commission must be contacted by the Coroner so that a "Most Likely Descendant"can be designated.

The Site consists of approximately 3.16 acres, identified as Assessor's Parcel Number (APN) 019-401-019. The property will hereinafter be referred to as the "Site" or "Subject Property". Mr. Craig Lawson of Pinnacle Homes has ordered this ESAto evaluate the potential impact from hazardous materials at the Site and other properties in the vicinity. This evaluation is based on information obtained from Federal, State and local agencies, interviews with people familiar with the Subject Property and adjacent properties, areconnaissance ofthe Subj ect Property and adj acent properties, and areview of aerial photographs, historical, and current documents pertaining to the Subject Property. SCOPE OF SERVICES The ESA includes the following: Review of available documents pertaining to the Subject Property, including a 50 -year chain -of -title report, and topographic maps related to the development and current physical nature of the Subject Property. • Review of an environmental database report which lists sites, including the Subject Property and adjacent properties, within a 1- mile radius that have been included on Federal, State, or local agency lists such as the National Priorities List (NPL), Comprehensive Environmental Response, _ Compensation, and Liability Information System (CERCLIS), Resource Conservation and Recovery Information System (RCRIS) Sites, registered and leaking underground storage tanks (USTs), and emergency response notifications (ERNS). Conducting a Site visit to evaluate property use and inspect for visible evidence of the generation, use, storage, or disposal of hazardous materials. Interviewing known available parties knowledgeable about the Subject Property to research previous Site uses and any past or current onsite hazardous materials usage, storage, or disposal. i Summarizing the results of the findings of our assessment in this report. This report will also provide recommendations for further evaluation, if appropriate. LIMITATIONS The judgements, conclusions and recommendations described in this reportpertainto the conditions judged to be present or applicable at the time the work was performed. Future conditions may differ from those described herein, and this report is not intended for use in future evaluations of the Site unless an update is conducted by a qualified professional. TTC did not evaluate the presence of suspected asbestos containing materials, lead paint, radon, or polychlorinated biphenyls (PCBs) in lights or transformers, as this was outside of our scope.

This report is provided for exclusive use by Pinnacle Homes. Use by a third parry requires written authorization from TTC and Pinnacle Homes. SUBJECT PROPERTY RECONNAISSANCE Site Location The Subject Property is located on I Street in the southwestern portion of Petaluma, California. The Site is adjacent to the City of Petaluma and Sonoma County border. Grevillia Drive is north of the Subject Property and I Street borders the property to the east. The approximate Site location is shown on the attached Site Location Map, Plate 1. The Subject Property is in an area of rural ranches and residential uses. Site Description TTC personnel performed a Site reconnaissance of the Subject Property on May 28 and June 2, 2004. The Site consists of approximately 16.28 acres of land comprised of rolling hills and grassland. Structures on the Site are grouped on the southeastern portion of the Site and include a residence, four outbuildings and an unused water tank house. The Site and vicinity are depicted on Photo Plates A through E, included in Attachment 1. Underground Storage Tanks 1 Observations made during the Site reconnaissance did not reveal any evidence indicating the presence of f underground storage tanks (USTs) on the Subject Property. Available historical information reviewed did not indicate evidence to suggest that USTs have been located at this Site in the past. Aboveground Storage Tanks iNo aboveground storage tanks (ASTs) were observed during the Site reconnaissance. Based on information received from neighbors, an aboveground fuel storage tank was located on-site, east of the former water tank house. The AST was used to fuel as many as ten ice cream trucks which Mr. Hash owned and operated. Neighbors indicated that the ice cream business operated in the 1970's. There was no pump island associated with the AST and the assumption is that it was gravity fed. During the Site reconnaissance the area where the former AST was located was carefully examined for visual or olfactory evidence of fuel spillage. No staining or smell was discernible. City of Petaluma and Sonoma County files contained no references to the AST. Other Observations i The Site appears to have been unused for some time. The bushes along I Street are very overgrown and the outbuildings are in various stages of disrepair. There was no evidence of the storage or manufacture of hazardous materials. The house was heated by a fireplace. No ponds, pits, sumps or other water bodies were observed. The Site is connected to City of Petaluma sewer and water. No distressed vegetation was observed. There were no noxious odors. Adiacent Properties Based on the Site reconnaissance performed on May 27 and June 2, 2004, interviews with neighbors, and a review of historical records and historical topographic maps, the vicinity has been primarily working ranches since at least the early 1900's. In 1990 Mr. And Mrs. Hash sold the eastern 3 acres of the ranch to Condiotti Enterprises. These 3 acres were subsequently built with single-family residences which remain adjacent to the Subiect Property. Other adjacent properties include working ranches with horses and cattle, and residences which were built in the 1950's. There was no evidence of the manufacture or storage of hazardous materials observed at adjacent properties. GEOLOGIC AND HYDROGEOLOGIC SETTING The subject property is located in the Coast Range Geomorphic Province, a series of north-west trending ranges separated by parallel river valleys. Based on review of Special Report 120 (Geology for Planning in Sonoma County, 1980) the site is underlain by the Franciscan Assemblage consisting predominantly of graywacke-type sandstone and shale with minor greenstone, conglomerate, chert and limestone. Site specific hydrological information was not available for the subject property.

The 3,135 acre parcel was subsequently deeded to Debra Investments. On December 12, 2000 Eugene T. and Lydia S. Hash deeded the remaining approximately 16 acres to Keith and Sherry Neuendorff. Detailed chain of title information, including a Chain Sheet prepared by North American Title Company, is enclosed as Attachment 2. Historical Tonoeraphic Map Review Historical topographic maps (enclosed in Attachment 3) of the Site and vicinity were reviewed. Topographic maps included the years 1912, 1954, 1968, 1973 and 1980. The 1912 map shows four buildings in the vicinity of the Site. The 1954 map shows the current residences in the vicinity. The 1968 map shows the residence and an outbuilding. The 1973and 1980 maps are show the same residence and outbuilding. Aerial Photograph Review Aerial photographs from 1965 and 1993 (enclosed in Attachment 3) were reviewed. The 1965 photograph shows the residence and one outbuilding. The 1993 photograph shows the Site in it's current configuration with the residence and outbuildings, as well as the newer residences along Grevillia Drive. All of the photographs indicate that the area has remained rural and relatively unused. Citv Directory Abstract The City Directory Abstract (enclosed in Attachment 3) was available for the Subject Property from the years 1954 through 2004. The Subject Property was listed in 1972 as Hash's Saddle Shop, Red & Gold Pony Farm and Hash Ice Cream. Surrounding properties are listed in 1972, 1981 and 2004 as l residences. Personal Interviews Kathy Mitchell of the Cedar Hill Ranch located at 27611 Street (across I Street to the south of the Subject Property) was interviewed on May 28, 2004. Her family has owned the 27611 Street property since the 1950's and she is familiar with the Subject Property. Ms. Mitchell indicated that the Subject Property had been a working ranch with horses and cows. Mr. Hash bred horses and had Shetland ponies for the local children to ride. Mr. Hash also owned approximately 10 ice cream trucks which distributed ice cream throughout the City of Petaluma. The trucks were fueled by an aboveground fuel storage tank (AGT) located to the east of the former water tank house on the Subject Property. Ms. Mitchell stated that there was no pump associated with the AGT. REGULATORY AGENCY LISTS AND RECORDS REVIEW An Environmental Data Resources, Inc. (EDR) environmental database report was obtained and reviewed for the Subject Property. The EDR report, enclosed as Attachment 4, lists properties within the minimum search area listed that were included in any of the regulatory agency databases. The locations of these sites are shown on the maps that are part of the EDR Report. The results of this database search and additional data obtained from other regulatory agencies by TTC are discussed below. Agency Lists EDR researched Federal, State and local regulatory agency databases to meet ASTM Standard E-1527 requirements within a one -mile radius of the Site. Sites which are within a one-quarter mile radius of the Subject Property are discussed below. Sites within a one-quarter mile radius which are listed for permits only or have a regulatory "No Further Action" status are not discussed. Sites which are located at a distance greater than one-quarter mile from the Subject Property were not deemed to pose a threat of adverse environmental impact to the Subject Property and are listed in the EDR report, Attachment 4. One site was identified within a one-quarter mule radius of the project Site. The Bostrom Property, located at 479 Deer Creek Lane, was reported as having had a leaking underground fuel storage tank (UST). The site was investigated under the oversight of the San Francisco Bay Regional Water Quality -5- Control Board and was given a Case Closed - No Further Action status. Petaluma Fire Department Fire personnel indicated there are no records of hazardous materials spills or responses or other environmental concerns related to the Subject Property. San Francisco Bay Regional Water Quality Control Board A telephone interview with John Jang of the San Francisco Bay Regional Water Quality Control Board indicated that there were no records on file for the Subject Property. Sonoma County Department of Emergency Services Personnel indicated by telephone that there are no records on file for the Subject Property. Sonoma County Department of Environmental Health A telephone response indicated that there are no records on file for the Subject Property. Sonoma County Permit and Resource Management Department Records were reviewed on May 25, 2004. The were no files for the Subject Property. FINDINGS Based upon available information, this assessment has revealed no evidence of recognized adverse environmental conditions in connection with the Subj ect Property. It appears that the Subject Property has historically been a working ranch with horses and cattle. Anecdotal information from neighbors did not indicate any Imowledge of hazardous materials usage at the Subject Property. Nearby properties have been ranches, with residential development beginning in the 1950's along I Street to the southeast and subdivision to the east of the Site in the early 1990's. CONCLUSIONS This Phase I Environmental Site Assessment has been performed in conformance with the scope and limitations of ASTM Practice E1527 for the project site located at 2762 I Street In Petaluma, California. Any exceptions to, or deletions from, this practice are described in the Limitations Section of this report. Agricultural chemicals or other hazardous materials may have been used on the Subject Property and nearby properties. However, no known spills, storage or intensive use of agricultural chemicals is documented. Therefore, we judge the environmental risk from agricultural chemical use to be minimal. Additional research could uncover as yet unknown information pertinent to the Site. If additional 1 information is required, please notify us and we will prepare a budget estimate for the services requested. ,1 �_l PLATES I ... .......
