MARCH 1, 2004 AGENDA REPORT FOR SOUTHTGATE RESIDENTIAL DEVELOPMENT EXECUTIVE.SUMMARY The applicant, Basin Street Properties, has submitted applications for the Southgate Planned Unit Development. The current plan proposes a _total of 216 detached single- family homes and includes. a 2.51 -acre future affordable senior /disabled housing site (Parcel A) that could be developed with a maximum of 80 units. Proposed land dedications to the City include a 1.09 - acre public park (Parcel B),,,a'stormwater detention facility /linear open 'space along the south side of the site within the Urban Separator and adjacent to the City limits (Parcel C), a 1.12 -acre parcel at the comer of Frates Road arid. Lakeville Highway (Parcel b), and several linear parcels along Frates and South Ely .Road -to be used for entry landscaping (Parcels E -K). Vehicular access to the site is proposed at two points along Frates Road. that coincide with the existing Calle Ranchero and Lakeville Circle intersections with ` Frates Road. An additional access is proposed along the South Ely Road frontage between.Lots 209 and 210. The Planning Commission reviewed this project at its January 27, 2004 meeting. After considerable discussion the project, the Planning* Commission, by-a vote of 4/3, forwarded a recommendation to the City Council to approve the project applications on the condition that certain additional information, be, submitted by the applicant and revisions to the project be made prior to the project being considered' by the City Council. The details of the changes, which were agreed to by the applicant at the meeting, are outlined in the attached minutes of the January 27, 2004 Planning.Commission meeting. While many of the Planning Commission. recommendations are reflected in the attached plans and materials not all of the information requested by the Planning Commission has been provided. In addition, tsome of the projectrevisions are not consistent with staff's, understanding of the Planning Commission recommendation. The Initial : Study /Mitigated Negative Declaration, Mitigation Measures and Draft Conditions of Approval have been revised to reflect the current proposal and to ensure that all Planning Commission recommendations and mitigation measures are implemented. 2. BACKGROUND For a discussion of site history, conformance with ' General Plan policies, and project issues, please refer to the staff report prepared for the December 9 2003, Planning Commission meeting and memorandum prepared for December 16, 2003 meeting. Plannin- Commission Review As .noted above, on January 27, 2004, the Planning Commission conducted a public hearing on thep project (please see 'Pl'anning Commission Staff Report and minutes, Attachments 2 and 3). • The Commission voted 4%3 to forward. a recommendation to the City Council to approve the project applications on the condition that certain additional information be submitted by the applicant and revisions o the project be made prior to the project being considered by the City Council. The Planning Commission recommendation is detailed in the minutes of the January 27, 2004 Planning Commission meeting, and is discussed further. below. It should be noted that the. Commission's recommendation is based in large part on commitments made by Basin Street 1 at the Planning Commission meeting. Revised Plans • The applicant was provided a memorandum which contains staff's understanding of the consensus items reached by the Planning Commission that were, to incorporated into the project presented to the .City Council (Memo from Jayni Allsep to George White, dated January 29, 20.04). a The applicant submitted a packet of materials on February 6, 2004, which included some useful information regarding their revised proposal, however, the plans were not complete in that they did not` include a revised grading and utility plan, conceptual landscape plan, and much of the information typically required for a proposed vesting tentative map. ® Staff prepared•.:a list of revisions and information to be provided with the complete set of plans and materials to be reviewed by the City Council (Memo from Jayni Allsep to George White, dated February 10, 20.04). This.list was based on staff review of the packet of information submitted by the applicant on,February 6, 2004. • The , applicant 'submitted one revised set of plans on Friday, February 13­2004, which were more complete. Additional copies: of these plans were provided -on Tuesday, February 17, 2004, for distribution to staff and other agencies for review and.comment. It is staff's opinion that the revised plans submitted by the applicant do not provide all of the Commission. In addition, some of the project revisions are not consistent wi g Information .requested, nor does It address all of the changes directed b the. Plannm p ) with staff s understanding of the Planning Commission recommendation. Due to the applicant's desire for the Southgate project to be heard at the City Council meeting held on March 1, 2004, the revised plans are being. forwarded'' to the City Council al'orig with a staff analysis that focuses- on the extent to which the revised :proposal conforms to the recommendation of the Planning Commission. Please note that proposed conditions of approval would.require changes that could affect the size and/or the number of single - family lots within- subdivision. An applicant is usually required to make these changes before a Vesting Tentative Map "is presented to, the City' Council forxeview and approval. Should'the City Council wish fo approve the Vesting Tentative Map at this time, these changes would need to be reflected on the Final - Map submitted to the City. 3. STAFF ANALYSIS OF REVISED. PLANS Gateway Elements The Planning Commission recommended that the revised plans submitted for 'City Council consideration include: ® Landscaped ` elements at the Prates /Lakeville corner, 'and. at other end of the Lakeville n6ise wall, near ,PG&E easement /Urban Separator. These gateway elements are to be constructed by `the developer as part of the project. The attached plans for the project provide' fora .1.12 -acre parcel .at the corner of Lakeville Highway and Frates Road (Parcel D). The Conceptual Master Plan submitted with the revised' proposal shows this parcel being landscaped with a variety of trees and groundcover, as "well as a 2 turf area and. path that connects to an off - street path proposed along Frates Road. At the other tr end of the property along Lakeville: Highway, within the PG &E easement/Urban Separator (Parcel C), the 'Conceptual Master Plan shows a circular landscape /path feature that terminates Within the proposed °detention area. Several linear parcels along Frates Road and South Ely Road • are ,also 'identified as "Landscape Entry Features" on the Vesting. Tentative Map (Parcels E through K). Staff has included , a. condition of approval which requires that a Master Landscape Plan be reviewed and approved by SPARC. This plan shall include details of the "Gateway" elements and landscape entry features In addition, staff has included conditions that require dedication of Parcels B through K to. the City; 'and the establishment of a .landscape assessment district for the maintenance of these parcels, except for Parcel B, the public park, which would be maintained by an annuity established by the ,applicant (see attached memo from Jim Carr, Director of Parks and Recreation, February 19, 2004). Noise Barrier /Aesthetic Issues The Planning Commission made the following recommendations regarding the proposed noise barrier: ® Modify the project to provide for an 8 to '10 -foot wide landscaped area between Lakeville highway and the noise wall. In addition, the Commission encouraged the applicant to pursue_ obtaining an encroachment permit from Caltrans to provide additional planting area along Lakeville highway. The revised street sections for Lakeville Highway (Sheet C 71.3) provides for an eight -foot foot wide planting area between the outside of the noise wall and the Lakeville Highway right -of -way i (ROW), and a 24.5 -foot landscaped area with a path along Frates Road. The Conceptual Master Plan shows a solid line' that presumably represents the location of the proposed noise wall, although there is no legend that identifies it as such. A climbing vine (Virginia Creeper) and variety of trees are proposed to be planted along Lakeville Highway and Frates Road, in the landscape areas on the outer -side of the' noise walls: Although the planting area in front of the wall has been widened to eight feet, there does not appear to be any planting area proposed along the inside of the wall facing the proposed homes. As noted above, a.proposed condition would require the establishment of a landscape assessment district for the maintenance of all .landscape areas (Parcels C through K) of the subdivision. In addition, ;staff has included a condition that would require the sound wall and landscaped area adjacent to Lakeville Highwayright -of -way be dedicated to the City and included in the area to be maintained by4he landscape assessment district. The Planning Commission also recommended that: The noise study shall include hard data (not just conclusion), which demonstrates that project conforms to General Plan noise standards for residential development. The applicant's February 10 letter indicates that due to changes to the development plan, approximately 560 linear,feet of sound wall has been removed. The street sections provided with • the engineering, plans depict an eight -foot sound wall atop a retaining wall along Lakeville Highway, and a sound wall along Frates Road (height is not specified), According to the one - page noise study addendum prepared by Rosen Goldberg & Der, dated February 6, 2004, noise wall heights are 6 -10 feet; however, this may not include proposed retaining wall heights that would result in greater total wall heights in some areas. The Noise study addendum attempts to provide information requested by the Planning Commission, a table which indicates the calculated sound levels along.Frates and Lakeville that would be acceptable, ;assuming a 6 to. 10 foot tall noise barrier (emphasis added). The addendum .further notes that this data is based on the acoustical consultant's review of a site plan sent to them on , 6 February 2004 (which did not included revised engineering ,plans) and the previous grading plan. Given the lack of information provided in the revised plans regarding: the proposed, noise, tamer, mitigation measures contained in the revised Initial Study have been revised to require that: 1) The applicant submit an acoustical :report which demonstrates that the specified location, construction and height of the proposed noise walls will provide °the mitigation necessary to comply with •the Ldn 45 .(interior) and Ldn 60 (exterior use areas) noise standards established in the .City. of Petaluma General Plan. The condition requires that the.study be submitted prior to approval of the improvement plans, shall be subject to peer review, and shall be approved by the Director of Community Development prior to approval of the Final Map; and 2) The noise wall design and landscaping be reviewed and approved 'by SPARC prior to approval the Improvement Plans., Public Park/Open Space.Parcels ThePlanning 'Commission requested that the public park, initially proposed adjacent to the Senior Commission n site Parcel .A be relocated, adjacent to the Urban Separator/PG &.E easement. OF also requested that the plan address issues raised in a memo from Jim Carr, Parks Director dated December 16, 2003 (Attachment 6). Revised plans submitted for City Council , review shows the park;being relocated along the Urban Separator /PG &E easement, as recommended' by the Planning Commission. These revised plans were submitted to Jim Carr and were reviewed by the Recreation, Music and Parks, Commission at their .meeting held on February 18, 2004. The Recreation, Music and Parks Commission made the recommendations for the Southgate_project, as outlined in the email from Jinn Carr dated February 19, 2004 (Attachment 7),. and summarized. below:, • The park shall,be developed with a playground along the same scale as the playground recently approved for the Gatti Subdi ision, and plans for the playground shall be reviewed by the Recreation, Music and Parks Commission prior to subm=ittal to SPARC • The applicant shall provide an annuity to cover the annual .maintenance, costs of the park; estimated to be $10,000 per year: The bike /pedestrian path located. in the urban separator currently terminates in a turn . around at the southwest edge of the property. The path is to connect to the residential street that parallels Lakeville Highway possibly traversing between parcel 33 and the proposed sound wall. 0 4 ® All landscape maintenance on Frates Road, Ely Road, Lakeville Highway and in the urban' separator is to be maintained through a landscape assessment district. These recommendations have been incorporated into the 'proposed conditions of Vesting Tentative Map. Urban. Separator The Planning Commission recommended that: ® The Urban' Separator along South Ely 'Road ,be increased to a minimum of 35 to 40 feet by decreasing the lot°dimensions. The revised plans show open space parcels along South' Ely that would provide for a landscape area in ranging froml6.5 to 19.5 feet in width along the South Ely Road ROW (Parcels J and K). An additional 26+ feet of landscaped area is proposed within the South Ely Road ROW.. This is not. consistent with staff's understanding of the Planning Commission recommendation, which directed that lot dimensions be modified in order to provide a wider landscape area that would serve as the Urban Separator along South Ely Road. In addition, frontage improvements to Ely Road., as required by the Municipal Code, could limit the opportunity for landscaping within the right -of -`way. Furthermore, landscaped areas within a streetright =of- -way have not historically qualified as Urban Separator. Setbacks /Development Standards The Planning Commission recommended that: • The Southgate Development Standards be amended to provide for a minimum 20- '. _ foot rear yard setback :except for lots with rear yards that `back up to Urban Separator, which shall have a. minimum rear yard of "15`feet; and • The exceptions noted in the previous PUD Developmenf.standards, which addressed encroachments permitted with the minimum setback area, be deleted from the table in the Development Standards. The revised Development Standards submitted with the current application stipulate a minimum 20 -foot rear yard setback. However, the proposed Development Standards still provide for exceptions to Tallow front porches to encroach"into the front and side yard setbacks. Staff has included a condition of approval' which requires that revised Development Standards be submitted concurrent with plans for SPARC review which address the following: 1. Clearlyspecify 411 permitted and conditionally permitted uses for the site. 2. Clearly specify permitted !and conditionally permitted accessory structures 3. No encroachments /exceptions- for yard isetbacks 4. Revise: Development Standards to be consistent with approved Vesting Tentative Map, lot /parcel numbers and access points, as amended by conditions of approval. Access /Circulation After reviewing;the: initial application, Staffrecommended and the Planning Commission agreed that a project access be provided on South Ely Road, and a signalized intersection at Ely Road and. Frates Road be provided to mitigate traffic issues and p' rovide for increase bicycle and pedestrian ;safety on Frates Road. 5 The, revised plans provide: for a project access. on South Ely .as recommended. In addition, the applicant proposes the following intersection controls at the project: Frates Road at Calle Ranchero — Traffic signal Frates Road at. Lakeville Circle - Stop control on sidet street Frates Road at South Ely: Road - Four -way stop control Although the traffic level of service (LOS) seems to be met with the revised ,prop_ osal, staff continues to recommend that a signal be installed at the Frates /Ely Road intersection in order to improve pedestrian and bicycle safety, especially for students, walking and biking to school. Conditions,, approval recommended by the 'City Engineer require that 1) traffic signals be constructed at both 'the Calle Ranchero /Frates Road .and .Ely Road /Frates Road'. intersections; and 2) the proposed entry street to he Southgate project at Lakeville Circle be eliminated and a, cul- de -sac constructed near lots 143 -146. Affordable Senior.Housing Site The Planning Commission recommended that: ® Development of the future senior housing site (now labeled as; Parcel. A require a Conditional.Use Permit subject to approval by the Planning Corhmission'prior to SPARC approval. • Plans presented to the City Council for approval be revised to provide a;second access to the affordable housing site. The applicant, revised the PUD •Development, Standards to identify, senior housing as a OF conditionally permitted use. In ,addition, staff is recommending a condition. of approval which requires that the. developer provide a signed disclosure to property owners .of the single- family lots within the Southgate development, .indicating that they are aware of the maximum density,. building height and setbacks for the future senior, housing site, identified, on the 'Vesting Tentative Map as Parcel "A ": Regarding access to the senior housing site, revised plans propose access from two interior streets on. the southeast side of the senior housing site: The cross - section .submitted. for these two streets, which are identified as alleys propose 'a� total street width of 30 feet, with two 1.2.5 feet travel lanes and a sidewalk on one side of the street. Conditions of approval recommended by the City Engineer would require that these streets be at least 32 -feet wide with sidewalks on both sides. In addition, a proposed condition of approval would require that ,a temporary a11- weather turnaround be provided on Parcel A (senior_, Housing .site) for thoset two streets that dead -end at Parcel A until the parcel is ultimately developed. Environmental Review It was the recommendation of the Planning, Commission that the Initial Study, which serves as Q P J the CE QA document for the ro 'ect be revised to reflect the revised project to. be presented to the City Council. Staff has revised the project description contained.in the Imfial. Study to reflect the proposed project presented to the City Council, as reflected' on plans submitted February 17, 2004. In .addition, the checklist and mitigation measures have been revised accordingly. Since • the changes; to the Initial Study are minor, re- circulation of the CEQA .document is, not warranted provided that that applicant agrees to implement the adopted mitigation measures. 6 � 4. ALTERNATIVES'. a. The City Council may approve the proposed project with modifications to the • conditions of approval and /or to the conditions previously modified by the Planning Commission; or b. The City Council may continue the :application. and request that the applicant make additional revisions to the project applications and provide additional information, as recommended by the Planning "Commission. c. The City Council may deny the request for the PCD Amendment and Modified General Development Plan. FINANCIAL IMPACTS This is a private development. project subject to standard cost recovery fees and any applicable City Special Development Fees. 6. CONCLUSION: The Planning Commission recommended that the City Council :approve the project applications for Southgate on the condition that certain revisions were made to the project, and additional information provided prior to the project being considered by the City Council. Should the City Council wish to approve the project applications at this„ time, staff recommends that the conditions contained in the attached resolutions be adopted to ensure that all Planning Commission recommendations and mitigation measures are ;implemented. • 7. OUTCOMES OR PERFORMANCE MEASUREMENTS THAT'WILL IDENTIFY SUCCESS OR COMPLETION: The Planning Commission found that the proposed General Plan Amendment, Rezoning, and PUD Development Standards contained in the Southgate Neighborhood Plan, with recommended modifications, would not create any significant environmental impacts and that the proposed project, would be consistent with the General Plan, the Zoning Ordinance, the Municipal Code, and recommended that the City Council approve the project, subject to their revisions. 7. RECOMMENDATION The Planning Commission' and Staff recommend that the City Council 1) adopt resolution adopting the revised Mitigated Negative Declaration; 2) adopt, resolution amending the General Plan, land use designation from "Specific Plan Area" and , "Transit Terminal" to "Urban Diversified"; 3) introduce an ordinance to rezone the property from Study District to PUD- Planned Unit Development; 4) adopt resolution approving the. Southgate Unit Development Plan and PUD Development, Standards; and 5) adopt resolution approving the Vesting Tentative Map for the Southgate Development.: • Aw T, �0 l liti..�•r. r i � , 4$* vi,L A.....

Mr. White addressed the following issues: Urban. Separator, noise 17 high retaining walls, vehicular and pedestrian's access and safety, non - residential 18 component to the project, 19 20 Chair Barrett: Is the alternative site plan shown here this evening what the Commission 21 should be considering? 22 23 Matt White: Yes. 24 • • 25 Council Member Harris: Asked if the applicant had support of the Del Oro group for the 26 alternative site plan? 27 28 Matt White: Yes. 29 30 Commissioner McAllister: Will retention areas be a site amenity or engineered retention 31 areas? 32 33 Vin -Smith: They will be both and more natural in the final design.. 34 35 Chair Barrett: Asked for clarification of the paths in the retention area. 36 37 Vin Smith: Have not been fully designed ,yet — the concept is that the drainage from the 38 subdivision would flow through there before going to the storm drains, howevet.the area 39 will also serve as a park with walking paths. 40 41 Commissioner McAllister: How many months would the area actually be usable as a 42 park? 43 44 Marty Parissenti: In large storms, you may get 18 inches of water over portions of the 45 area. Do not know .if it would be suitable for a baseball field, however, would be suitable 46 for walking paths most of the year. 47 2 Planning Commission Minutes - January 27, 2004 • 1 2 Commissioner McAllister: You would see it as more of a passive park, only used approximately 9 months of the year. 3 4 Marty: Possibly could have, soccer fields. 5 6 Matt White: The intent is apassive'park. 7 ,8 Commissioner von Raesfeld: According to the December 9` site plan, the affordable 9 housing area would need additional access for emergency services, how would this be 10 achieved? I1 12 Matt White: Has been addressed on the alternative site plan. 13 14 Commissioner von Raesfeld: Do you have solutions to Jim Carr's memo dated 15 December 16, 2003? 16 17 Matt White: No. 18 19 Commissioner von Raesfeld: Do you have a City Council date? 20 21 Matt White: February 23, 2004. 22 23 Commissioner Asselmeier: Asked what the affordable units would look like? • 24 25 Matt White: Don't know yet — are just beginning the design. 26 27 Commissioner Asselmeier: Are there restrictions to what can be put on the PG &E 28 easement. 29 30 Matt White: For overhead transmission lines only. 31 32 John, North Bay Construction:- According to PG &E they have no future uses for it. All 33 PG &E requires is access on the easement. 34 35 .Matt White: We own the land; they have an easement for poles and lines. 36 37 Barrett: What deten-nines the number of units for the affordable units. 38 39 Matt White: Is up to PEP — they will design the project. As part of approval we are 40 asking for this zoning. 41 42 Public Hearing opened: 43 44 Art Kerb el, Adobe Del Oro,Action Group: Neighborhood is in support of the project. 45 Current -plan is a result of the developer and the neighborhoods working together. Urged • 46 the .Commission'to think about where the City wants to go. Residential is the key to the 47 project. If project is something other than residential, there will be more residents to 3 Planning Commission Minutes - January 27, 2004 1 protest; a density of 21.6 houses is the maximum. the community agrees to. Regarding , 2 Frates Road — this is the most adaptable solution for the traffic on this road. This will •. 3 slow the truck traffic down. Urge the commission to approvethe plan presented tonight. 4 5 John McGinns, President Adobe Creek Homeowners: Agree with everything Mr. Kerbel 6 has said.. The current plan mitigated most of the neighborhoods concerns. We support 7 the project as proposed tonight. 8 9 Mark Albertson, 1676. Calle. Ranchero: Live directly adjacent to the project; Chair of the 10 Adobe Del Oro Neighborhood Group. Group has advocated for a low impact and low - 11 density project. If other land uses are discussed during deliberation, would .like public 12 comment opened up again. Focus of the applicant and the neighborhood is now on Frates 13 Road. When Lakeville Road was widened it changed the traffic patterns on Frates Road. 14 The most significant impact is truck traffic. Goal is to reduce the speed of truck traffic 15 'and provide safety for the neighborhood to cross Frates Road. Want a 4 -way signal at 16 Calle Ranchero, and a 4 -way stop at Frates and Ely. Asked to reclassify Frates and keep, 17 as a two -lane street, posting speed limit and providing pedestrian cross walks: Want to 18 encourage a well- designed sound wall on Lakeville. If you do traffic calming and have 19 trees on the street and make it unfriendly to trucks, it will reduce the noise. Reduce the 20 traffic generating the noise. Action Group endorses the current proposal as conditioned 21 regarding Frates Road. 22 23 Vera Ciamnietti, Director PEP: Thanked the Commission for the questions tonight. 24 Consider this a great opportunity for affordable housing. More than likely , there will be • 25 78 to 80 units. Will build larger units to accommodate people with special needs. Will 26 hope that public transit will be available by the time the units are built. Current PEP 27 residents are served by volunteers and Petaluma People Services. Retail is not ,necessary 28 for the residents that we serve. I am not in favor of 3- stories, is cost prohibitive and not 29 as user friendly to seniors. Would like it more like our Edith Street project as opposed to 30 the Lieb Apartments on Douglas Street. 31 32 Mark Ferguson, 112 Rancho Bonito: Am a neighbor who has followed this project. 33 Want future developers work with neighborhoods such as Basin Street did. Urge the 34 Commission to approve the project. 35 36 - Christopher Costin:. Represent property owners south of the project. Support the project. 37 Applicant has spent a lot of time with the neighborhood., Have a concern ,about a revision 38 in the site plan shown tonight: My client's property is outside of the City limits. This 39 property is designated as a potential expansion area. Do not want to restrict future 40 development with the design of this project. The new design leaves a street along PG &E 41 access. Want the potential for two access, routes into the open separator for a potential 42 expansion area. Could be done possibly with the loss of 1 or 2 houses. 43 44 Jack Osman, 1890 Falcon. Ridge Road: Agree with the .comments . of the other 45 neighborhoods. The- proposal is a dramatic improvement over the previous proposals. 46 Thanked the applicant for working with, the neighborhood. I have one : issue regarding • 47 access on Frates Road. Want effective traffic calming, clearly identified cross walks, and 4 Planning Commission Minutes - January 27, 2004 'Y 1 2 a reduction in the speed limit. Support the proposal. 3 Dev Goetschius, Housing Land Trust: Southgate is an opportunity for Housing Land 4 Trust to. build 3 homes in Petaluma. We are pleased to collaborate with Basin Street 5 Properties on this project. 6 7 Public Hearing closed: 8 9 Chair Barrett: Would like to hear from traffic and noise consultants before discussion by 10 the Commission. 11 12 Vin Smith: The consultants are not here this evening. I will answer any questions. 13 14 Chair Barrett: Asked why there was no noise assessment on Frates Road closer to 15 Lakeville. 16 17 Vin Smith: Showed where monitors were placed for the noise assessment. Follows the 18 recognized criteria. 19 20 Chair Barrett: Asked for rationalization of timing of traffic counts which took place at 21 non -peak hours and on a holiday but not during am and pm peak periods. Have the same 22 comment for the noise readings. ® 23 24 Vin Smith: We relied on the experts to conduct the noise and traffic studies. 25 26 Chair Barrett: Referred the Noise Mitigation Study dated November 13, 2003. There is 27 no hard data in the study supporting the summary. 28 29 Vin Smith: Summary states interior and exterior noise will be in compliance with the 30 City's goals. 31 32 Commissioner Asselmeier: To avoid 10 -ft sound wall on Lakeville and Frates, what 33 would set backs have to be? 34 35, Vin Smith: We did not ask that in the analysis of the noise. 36 37 Commissioner Asselmeier: I have concerns that this project is a gateway to the City. 38 How could the soundwalls be adjusted to deal with this concern? 39 40 Vin Smith: There is 8 ft. of wall on Lakeville and 8 ft. on Frates. There will be a 41 significant amount of landscaping against the 10 -foot wall on Frates. Will be planting on 42 both sides of the wall on Lakeville — will be a green living wall. 43 44 Commissioner Rose: Regarding interior noise levels — will particular models be 45 mitigated according to their location? ® 46 47 5 Planning Commission Minutes - January 27, 2004 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 Vin Smith: The standard Title 24 building code requirements will take care of interior • noise issues. Committee identified project issues for discussion: • Gateway visual quality • Sound wall /noise • Feathering/Urban Separator /Access from Ely Road Jim Carr memo • Access • Housing types and lot sizes • Frates Road/traffic issues • Infrastructure issues • PEP site /Interface and access • Land Use /Smart growth • Density Break.at 9:00 Resumed at 9:1.0 Commissioner. von Raesfeld: Believe there are process issues — the Initial Study does not match the plan presented this evening. How can findings be made? • Chair Barrett: The studies presented in the; staff report must consider new ,plan and address issues. Do not believe the data presented can be imposed on this alternative plan. Council Member Harris: Do not want to bury this plan in process. Paul Andronico: The Initial Study looks at impacts — there are extremely minor differences between the two plans. The new plan has less impact — do not believe there is a legal issue. The noise study was revised — is not a legal issue from CEQA standpoint. George White: The applicant will need to agree to the mitigation measures. Vin Smith: We agree to most of the mitigations and made some minor adjustments. We would sign any differences. Commissioner Asselmeier: If we are giving staff further direction, it may be premature to discuss the issues. Commissioner McAllister: I do not think we are close enough to make a recommendation. • 6 Planning Commission Minutes - January 27, 2004 t 2 1 Chair Barrett: Do not want to be pushed on this process because the applicant has a Council date. To be fair, we need to .look at what is being proposed and look at it 3 carefully. Believe it would be wrong to push it through. 4 5 Council Member Harris: Believe that we should plug through this evening, do not want 6 to slow down the process — believe it is a win -win for the City. Would like to poll the 7 commission on going forward. 8 9 Commissioner von Raesfeld: Would like to discuss the issues. 10 11 Traffic /Noise: 12 13 Commissioner McAllister: Want staff to weigh in on the traffic calming proposed this 14 evening and the issue of noise. 15 16 Craig Spaulding: I have not reviewed or evaluated this alternative plan. I have read the 17 initial traffic report. I suggested access on Ely and controlling Ely intersection. 18 Pedestrian safety is paramount. They have proposed a signal and a 4 -way stop. 19 20 Commissioner McAllister: Is the unsignalized, free intersection of a concern to staff? 21 22 Craig Spaulding: Yes. • 23 24 Commissioner McAllister: How does the City weigh in on the requirements of the 25 County's memo. 26 27 Craig Spaulding: Do not feel there is an issue of capacity. 28 29 Chair Barrett: Regarding a stop sign instead of traffic light — is that better or sufficient to 30 bring LOS up from an E? 31 32 Craig Spaulding: I have not evaluated that. 33 34 Jayni Allsep: In reviewing a study of traffic engineering, Attachment C the conclusion is 35 cumulative traffic plus project, would make LOS go to E. Staff referred to General Plan 36 policy that level; of service C has to be maintained. The Initial Study uses the level of 37 significance of the General Plan. If there were changes to circulation and access - traffic 38 could be more evenly distributed and reduce the LOS. 39 40 Commissioner Asselmeier: What is density across the street as compared to the project? 41 42 Jayni Allsep: I;do not know the answer to that question. 43 44 Commissioner Asselmeier: Are there other situations where there are variations from the • 45 46 required urban separator — .other projects that do not comply. 47 7 Planning Commission Minutes - January 27, 2004 1 George White: On the 'West side it varies, the East side is almost entirely 300 feet. The • 2 sports ,complex on East Washington is the first project to allow a structure on the Urban 3 Separator. 4 5 Chair 'Barrett:. Regarding Mr. Albertson's letter addressing traffic calming — has there 6 been any study done? 7 8 Jayni Allsep: Would need to be a Council policy decision to reclassify Frates Road. 9 10 Chair Barrett: If you eliminate a signal -at Ely Road and put in 4 -way stop', have a four - 11 way signaled intersection at Calle Ranchero and Frates Road then the only safe crossing 12 would be at Calle Ranchero. 13 14 Jayni Allsep: That's correct. 15 16 Council Member Harris: What do we need to give direction on this tonight? 17 18 George White: Want direction on the new plan, apparently there is a time issue regarding 1.9 Basin Street's: council date. 20 21 Matt White: LOS is B at; Calle Ranchero intersection. Our alternative plan was 22 submitted December 9, 2003. We did not support access on Ely Road because it supports 23 urban sprawl. The City Council asked us to make the urban separator less than 30.0 feet. 24 • 25 Gateway /Noise Barrier /Aesthetic Issues: 26 27 Commissioner McAllister: I share the concerns of Commissioner Rose regarding the 28 southwest corner of the project. It is problematic to have a sound wall all the way-down 29 Lakeville. Having houses right up against Highway 116 would repeat mistakes. I am 30 supportive of the process with the neighbors; however, I believe their needs to be a 31 compromise in the corner that would be a gateway to our community? Maybe another 32 use on there is more appropriate. 33 34 Chair Barrett: In the General Plan Lakeville is called out as a scenic corridor and a 35 gateway to the .City. Project does hot promote either of these. Sound wall needs to be 36 treated well, the southeast corner of the PG &E easement and the southwest corner of 37 Lakeville Frates Road needs to.be used a gateway. 38 39 Matt White: Is acceptable to me to do a gateway at the corner of Lakeville & Frates and 40 on the PG &E easement. 41 42 Chair Barrett: How will landscaping be maintained along Frates Road? The City is cash 43 strapped. 44 45 Matt White: Will allocate some funds to the park to be maintained by the City. 46 47 8 Planning Commission Minutes - January 27, 2004 • 1 2 Commissioner von Raesfeld: Believe there is a win -win situation here. If three lots at the comer of Lakeville and Frates can be reconfigured, a gateway can be established as 3 well as the elimination of 100 -feet of sound wall. Is problematic that you only have 2- 4 feet to plant something against the sound wall on the Cal Trans right -of -way. 5 6 Matt White: Can establish an acre and a half of gateway. The project is not a perfect 7 solution, however, sound wall on Lakeville is now down to 8 feet. 8 9 Commissioner von Raesfeld: Suggested putting a more rnultilayered element of street 10 segment on the CalTrans side of the sound wall instead of development side. 11 12 Matt White: Can take the 4 -feet from the inside and put it on to the sound wall 13 (Lakeville) side of the wall to achieve an8 -10 foot landscape area between Lakeville and 14 the soundwall. Can put the 3 corner lots somewhere else. 15 16 Commissioner Rose: Do note feel we need to design the comer — could possibly be 17 developed into a transit center. It is the City's future to deal with that corner as a 18 gateway.-The details of the gateway are SPARC issues. 19 20 Commissioner Asselieier: Still have 600 -feet of sound. wall at 8 -feet. If sound wall is 21 moved, how does that effect noise levels? 22 23 Vin Smith: The noise threshold for backyard is driving the design. • 24 25 Chair Barrett.: Want to see data to support the effect moving the sound wall will have on 26 the noise levels. 27 28 Commissioner McAllister: Still has a concern about the gateway issue. Landscaping as a 29 gateway element — do not think we really know what it is we are negotiating here. Do 30 not feel this will accomplish,goals of a gateway to the City. Do not have an image of the 31 gateway being proposed. 32 33 Commissioner Asselmeier: Suggested these items be addressed, plan updated and 34 brought back to the Commission. 35; 36 Chair Barrett: T agree this should come back to the Planning Commission while Basin 37 Street is preparing to go to the Council. The project has been designed without 'the 38 gateway in it. 39 40 Public Park/Jim Carr Memo of December 16,2003: 41 42 Chair Barrett: How will the issue of the house abutting the park be dealt with? 43 44 Vin Smith: ,.Believe it is probably a security issue. Don't share Mr. Carr's concern and 45 do not know if it constitutes a redesign of the project. .• 46 47 Matt White: Will reconfigure to adhere to Mr. Carr's standards. 9 Planning Commission Minutes - January 27, 2004 2 Access /Circulation: • 3 4 Commissioner von Raesfeld: Access will be an issue when the PEP site is developed — 5 believe emergency services will want another access. 6 7 Commissioner Asselmeier: I- do not debate PEP's reputation, however, I would like an 8 opportunity to view the PEP plan. 9 10 George White: If PUD is adopted as .proposed, the PEP project will not come back to the 11 Planning Commission, it will go to SPARC. 12 13. Chair.. Barrett: Want houses that abut the affordable housing piece of the project to have. 14 written statements disclosing this information. 15 1'6 George White: Could require that the affordable .housing component be a conditionally 17 permitted use that would come back to Planning Commission as a CUP. . 18 19 Urban Separator /Feathering: 20 21 Chair Barrett: One of the best things about the East side is the urban separator — it 22 enhances the area — would like to. see. it carried on at more than 120 .feet. Urban separator 23 on Ely is non - existent — is a recipe for disaster. Believe 300 -feet is essential on both 24 sides of the project. • 25 26 Commissioner McAllister: Share the concerns regarding the 300- foot urban growth 27 boundary. Do not know why we are making an exception here. Part of what can make 28 this project special is having that open space. 29 30 Commissioner Dargie: There was a project ,approved. a few years ago that did not have 31 strict 300 -foot urban separator. Can understand why the applicant feels there is 32 flexibility. Do not support access on Ely Road. 33 34 George White: Point of clarification, City code requires Ely Road to be improved from 35 middle of the street to the property line regardless of access. 36 37 Commissioner Rose: General Plan alternatives shows :Ely Road as urban growth 38 boundary — this may be vacated and the road maynot continue to be a point of access. 39 40 Craig Spaulding: There are some roads that go to the urban growth boundary. 41 42 Commissioner Asselmeier: General Plan states this is a potential urban growth boundary; 43 want to observe 300 -foot urban separator. The current plan does not show any urban 44 separator on the'Ely side. Would want to support staff's recommendation to have access 45 from Ely, which- woul'd'- lessen the traffic impact on Frates Road. 46 • 47 Council Member Harris: Agree with Commissioner Dargie on this issue. 10 Planning Commission Minutes - January 27, 2004 • 2 Commissioner von Raesfeld: Am comfortable with the 120 -foot urban separator. Would 3 like to see what the :Ely Road separator would look like. Want to make sure SPARC 4 looks at this carefully. Needs to be an amenity for the project. 5 6 Matt White: I am fine with 'a condition. We can make improvements and dedicate to the 7 City. 8 9 Chair Barrett: Discussion on the last proposal gave up some of the urban separator 10 footage because it was a mixed -use project. This project is strictly residential and 11 therefore should adhere to the 300-foot urban separator. 12 13 Commissioner McAllister: One hundred twenty feet does not meet the urban separator. 14 The neighborhood is trying to dictate community issues and not just neighborhood issues. 15 The rules applied to the mixed -use proposal do not apply here. 16 17 Commissioner von Raesfeld: Asked if some lots sizes could be reduced to gain 15 extra 18 feet for the urban separator along Ely Road. 19 20 Matt White: Agreed that he 'could do that. 21 22 Commissioner McAllister: What if the interior open space were put on the exterior of the 23 24 project to create more urban separator: Then it would be seen` by the rest of the community as they drive by. 25 26 Matt White: Would be happy to explore. 27 28 Commissioner Asselmeier: If we expand the twenty feet on the Ely Road side to 38 feet, 29 does that get us closer to the continuity of the urban separator? 30 31 Commissioner Dargie: The 300 -foot urban separator is not on all sides of the 32 development. 33 34 Chair Barrett: This property has that obligation because it is on the urban growth 35 boundary on two sides. 36 37 Circulation to Ely: 38 39 Consensus of'the Commission: If it makes sense to the circulation of the project, will 40 leave up to the developer. 41 42 Chair Barrett: Need to be able to get to the LOS and need safety .issues addressed by 43 staff. 44 45 46 47 Planning Commission Minutes - January 27, 2004 1 Setback/Development Standards: 2 3 Commissioner McAllister: Houses are too large. for the lot sizes — need to .establish some 4 other parameters. 5 6 Matt White: The commission can dictate setbacks - can we agree to a 15 -foot back yard? 7 8 Commissioner McAllister: Would like 2.0 -feet and would compromise on the side yard 9 such as zipper lot configuration, however, that is SPARC issue. 10 1 l Matt White: How about a combined 30 -foot setback, with a minimum of 15 in back and 12 10 in front and 5 feet to play with. 13 14 Chair Barrett: How about 15 feet for property that backs onto the separator. 15 16 Commissioner McAllister: Support a larger back yard — 20 feet except 15 -feet where it 17 backs up to the urban separator. 18 10 George White' Do you want these issues to be dealt with before going to Council? 20 21 The consensus was that all identified issues and /or modifications should be finalized prior 22 to Council reviewing the project. 23 24 Infrastructure: 25 26 Chair Barrett: Water issues were dealt with in the Initial Study. 27 28 Matt White: Roads will be designed to City standards and dedicated to the City. 29 30 Commissioner von Raesfeld: Seems inappropriate to impose street maintenance on this 31 subdivision. 32 33 Commissioner Asselmeier: Believe this subdivision is different — the General Plan shows 34 that we do not need this housing ,at this time and therefore was it possible to create some 35 sort of private assessment to pay for street maintenance. Acknowledged that.some sort of 36 policy would need to be established first before imposing this as a condition 'on 37 development applications.. 38. 39 Commissioner Dargie: Believe this project should adhere to current standards. that other 40 subdivisions adhere to. 41 42 Chair Barrett: Can see both sides of the argument.— do not the have the answers. 43 44 Council Member Harris: Do not believe we should change the standards midstream. 45 46 Commissioner McAllister: Would like to see the final synthesis before recommending to 47 council. Realize this is a. unique application and it's urgency. Feel hesitant to 12 13 Planning Commission Minutes - January 27, 2004 • 1 2 recommend forwarding without seeing the project again. Do not want to set a precedent here. 3 4 Chair Barrett: Hesitant to approve something that we are have not seen. Many 5 improvements have been made — would not feel comfortable forwarding the 6 recommendation. 7 8 Commissioner Rose: What are logical consequences if it .came back to Planning 9 Commission. 10 11 George White: Probably could not schedule until March 9" 12 13 Matt White: Will work on the changes you proposed this evening while getting it ready 14 to go to the Council. 15 16 M/S Dargie /von Raesfeld to recommend adopting a Mitigated Negative Declaration, 17 approving a General Plan Amendment and rezoning to PUD with the following to be 18 finalized, as agreed to by the applicant, prior to City Council review and approval: 19 20 Prior to the public notice for City Council review: 21 22 1. Gateway /Noise. Barrier /Aesthetic Issues — The site serves as a gateway to the • 23 24 City. Noise wall along the road, as proposed, is not an appropriate gateway. a. Fix the "problem corner" near Frates and Lakeville by reconfiguring the 25 awkward lots in that corner. Relocate 3 lots elsewhere on site to maintain 26 same unit count for single-family homes. 27 b. Design a landscaped "Gateway" element at Frates /Lakeville corner. 28 Developer would be responsible to build the improvement as part of the 29 project_ 30 c. The above redesign would allow the height and' length of the noise wall 31 along Lakeville to be substantially reduced. 32 d. Design a "Gateway" element at other end of Lakeville noise wall, near 33 PG &E easement/Urban Separator. Developer would be responsible to 34 build the' improvement as part of the project 35 e. Provide' for wider planting area along the outside of the wall (toward 36 Lakeville). The proposed two -foot wide planting area is not adequate. 37 Modify yards within the project to achieve' an 8 -10 landscaped area 38 between Lakeville and the soundwall: Pursue the idea of an encroachment 39 permit with Caltans to widen the planting area. 40 f. The noise study shall include hard data (not just conclusion), which 41 demonstrates that project conforms to General Plan noise standards for 42 residential development. 43 44 2. Public-Park 45 a. All items in the memo from Jim Carr, Parks Director dated December 16, 46 2003 shall be incorporated into the project. 13 Planning Commission Minutes - January 27, 2004 1 b. Relocate park to connect to Urban Separator /PG &E easement, per Urban 2 Separator discussion.. 3 c. Eliminate lots backing up to park. 4 5 3. Urban Separator /Feathering 6 a. Decrease lot dimensions in order to increase Urban. Separator to 'a 7 minimum of 35 -40 feet along Ely Road. 8 b. Relocate park adjacent to PG &E easement /passive open space to,provide 9 more useful open space area/Urban Separator. 10 11 4. Setbacks /Development Standards 12 a. Amend Development Standards to provide for a minimum 20 -foot rear 13 yard setback, except for lots with rear yards that back up to Urban 14 Separator, which shall have a minimum rear yard of 15 feet. 15 b. Delete exceptions to minimum setbacks in Development Standards.. 16 17 5. Access /Circulation 18 a. Per Municipal Code frontage improvements to Ely Road are,-required as 19 . condition of project approval whether or not access on Ely is proposed.. 20 b. Per staff suggestions in 'the 1/27/04 staff report, access to /from Ely Road " 21 and a signalized intersection at Ely Road and Frates Road should. be 22 considered to mitigate traffic issue and provide for increase bicycle and 23 pedestrian safety on Frates Road. . 24 • 25 6. PEP /Affordable Housing Site 26 a. Amend development standards to make affordable housing a conditionally 27 permitted use. Details of the affordable housing project will return to 28 Planning Commission for a Conditional Use permit approval prior to 29 SPARC approval. 30 b. Provide a second access to the affordable housing site. 31 32 7. Environmental Review It was the consensus of the Planning Commiss'ioi that 33 the Initial Study, which serves as the CEQA document for the project, should be 34 revised to reflect the revised project that will be presented to the City Council. All 35 necessary information, including but not, limited to the following, shall be 36 provided the applicant to support these revisions: 37 a. A complete "set of plans for the revised project, including civil drawings, 38 street sections, a landscape plan, etc. 39 40 b. Revised PDP .Development Standards that reflect Planning Commission 41 recommendations regarding setbacks, Use Permit for PEP site, and any 42 other changes necessitated by the revised project design. 43 44 c. A revised Traffic Study that addresses the revised project, including 45 changes to access and internal circulation. In addition, ITE trip generation 46 rates referenced for the PEP housing site should be consistent-with the use 47 designated in the PDP development standards, which is a ffordable 14 Planning Commission Minutes - January 27, 2004 • 1 2 housing, not senior housing. Vin Smith revised project description to delete "Senior" housing from project description and development 3 standards, and as you know, senior housing typically has a lower trip 4 generation rate. While the difference may not be significant, the traffic 5 study should use the appropriate trip generation rate. 6 7 d. A revised Noise Study that includes the following; 8 o An analysis which demonstrates that the specified placement and 9 height of the proposed noise wall (based on redesign discussed above) 10 will provide the mitigation necessary to comply with General Plan 11 noise standards for residential development. 12 o Noise contours for future noise levels along Frates and Lakeville, as is 13 typically provided in a noise study for residential subdivisions. This 14 will provide the hard data requested by the Planning Commission. 15 o Reference to the traffic study /data used to determine future noise 16 levels, including the percentage of truck traffic assumed for future 17 traffic volumes. Truck traffic can have a substantial effect on traffic 18 noise levels. 19 o Applicant to agree to the mitigation measures and sign the initial 20 study/Neg.

The 4 Old Lakeville Road. right -of -way (proposed to be abandoned) separates the two parcels. The site, ATTAC H IVY E BSI T 3 Page 1 I which has a gentle north to south cross slope, is unimproved and is, sparsely vegetated with 2 remnant grasses. There are no trees on the subject property. In the past, the, property was used 3 as pastureland and for hay production. More recently, a portion of the site was used to stockpile 4 fill material from nearby construction sites for which muse permit was granted. A 120 -foot wide 5 PG &E transmission line right -of -way easement runs along the eastern edge of the project site: A 6 City pump station exists at the northwest corner of the site, near the intersection of Frates Road 7 and Ely-Road (see Location Map, Attachment B). 8 9 10 11, 12 13 14 15 16 17. 19 19 20 2 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 Existing Use: Vacant Proposed Use: Residential and Open Space Current Zoning: S- Study District Proposed Zoning: PUD- Planned Unit Development Current.

Development. proposes 221 detached single- family homes, a.1..34- acre public park and a 104 -acre parcel to be retained for future affordable housing (25 to 80 units). A stormwater detention facility /linear open space area. totaling approximately 4.46 acres is also proposed along the south side of the site adjacent to the City limits; Vehicular access to the site is . proposed at, two points along Frates Road that coincide with the existing Calle Ranchero and Lakeville Circle intersections with Frates Road. 38 The project entitlements include: 39 • A General Plan Amendment to 1) apply the Urban Diversified, land use designation, 40 which would allow residential densities of 540 units per acre; or 200 =400 housing units 41 on the project site; and 2) remove the "Transit" designation from the corner of Highway 42 116 and Frates Road; 43 • A Rezoning from the existing "Study" Zoning classification to Planned Unit 44 Development (PUD); • Page 2 "0 1 2 e A V e a stif g Tentative .Map that "would divide the site into 221 single- family parcels, one fordable housing site and three separate open.space'Ipark parcels; and 3 ® An abandonment of the Old Lakeville Road right -of, -way that currently divides the 4 property into two separate parcels at the western edge of the site. 5 6 The application for the establishment of a PUD "is required to be accompanied by a Unit 7 Development Plan, which includes an overall site plan, development standards and development 8 schedule. The schedule submitted for this PUD indicates that the single - family homes are to be 9 developed in three phases over a five -year period. • Phase l is anticipated to commence in late 10 spring /early summer of 2004 and it is anticipated that development` will occur at a rate of 50 11 homes built per year. The applicant, estimates that all single- family home construction (Phases I 12 through III) will be completed by late 20Q9. Phase IV of the Southgate neighborhood is an 13 affordable housing project of up.to 80 units. The, applicant has indicated that this phase may 14 occur concurrently with one of the three . single- family phases or it may occur following the 15 completion of all single - family homes. Following .City Council approval, the proposal will be 16 required to receive final approval for site plan, architectural and landscaping approval as well as 17 approval of the Planned Unit Development Plan for the proposal by the Site Plan & Architectural 18 Review Committee. 19 20 BACKGROUND 21 22 The subject property was annexed into the City in 1985 along with the Adobe Creek Golf and � 23 Country Club located northeast the project site. At the time of the: annexation the site's zoning l4 designation, Study Distrid, was purposefully retained for future interpretation. According to 25 staff reports pertaining to the annexation, the site was being considered for the development of a 26 200 -unit residential development. The site was later considered by the Santa Rosa Junior 27 College for its Petaluma campus and by local school districts for °..an elementary or junior high 28 school site. Ultimately, the site was deemed' unsuitable'for their needs. 29 30 During the 1987 -2005 General Plan rewrite, the City Council considered designating the site 31 Special Industrial, since they found the site to be well suited for a campus -like development that 32 would have an appropriate land use intensity and the potential to provide an attractive gateway to 33 the_ City, as well as a transition from the agricultural lands to the east within the County. 34 However;. due.to concerns regarding° a proposed residential development, the site was designated 35 a& a "Sp"ecific Plan Area inthe 1987- 2005 General Plan and accompanying land use map. 36 37 In September 1;_999, the ,project sponsor submitted a preliminary application to request that the 38 City Council reconsider the Specific Plan' requirement for the property. At that time, the project 39 sponsor envisioned the property being developed as a business park and proposed a Special 40 Industri`a17Office Park fand•use:designation for the site. The Council determined that the site did 41 not have characteristics typical of.a Specific Plan area, and that it was not. necessary to prepare a 42 Specific Plan, particularly in light of the proposed single ownership.. The council indicated that 43 it was appropriate for"the project sponsor to :move forward with an application for a General Plan 44 Amendment for the property, and expressed a desire to see an analysis of the jobs/housing 45 balance and an economic analysis of the optimum use of the parcel. 06 Page 3 I In August 2000, applications for a Mixed Use project were submitted, which proposed office, 2 R &D, retail and residential uses. Following several hearings, the project received a positive • 3 recommendation from the Planning Commission. The. City Council, however; -Aster - Tiined that an 4 environmental impact report (EIR) would be .required to 'assess the environmental impacts *of the 5 mixed -use proposal. Applications for the mixed -use proposal were subsequently withdrawn, and 6 in the fall of 2002, the applicant ,engag_ ed in an interactive charrette process that was intended to 7 reach a consensus development plan. 8 9 In late 2002, the applicant submitted :a proposal for 4,00 residential dwelling,unit's and 20,000_ 10 square feet of'commercial /mixed use space on project site. That proposal was also withdrawn. 11 12 In. July 2003,. the applicant submitted an .application, for the current Southgate. project, which 13 proposes single , family homes and a future affordable housing component, Th:e applicant -,has 14 indicated that the current. proposal is a result of "returning back to the , neighborhoods following 15 the charrette process,, listening to there and working directly with them to "respond -to their 16 desires." 17 18 STAFF ANALYSIS 19 20 General'Plan Consistency .21 The project has been reviewed for consistency with the Petaluma General Plan:. As ;noted above, .22 the applicant is requesting a, general plan amendment that would change the current "Specific 23 Plan Area and "Transit Terminal" designations' to an "Urban Diversif ed' designation, which 24 would allow residential densities of 5 to 10 units ,per acre, and invites flexibility in, site design and 25 single- family homes, duplexes, and multi- family units are permitted. The project, which prop . YP es single- family homes as well as future affordable housing, would conform to the 27 proposed Urban .Diversified designation. General Plan Elements containing policies that: apply 28 specifically to the site and /or require more detailed analysis to determine compliance are 29 summarized below: 30 31 Community CharacterVement 32' 33 Policy 2 - Within the context that growth will occur; every effort shall be made to preserve and 34 enhance the views of surrounding lands, hills and ridges. 35 36 Policy_ 6 - Well- designed developments that will be harmonious with their setting and /or enhance 37 the city's image shall „be encouraged. 38 39 Preliminary architecture and landscape plans submitted with the project applications demonstrate 40 that the 'applicant has made an effort to design 'the proposed Southgate neighborhood as an 41 attractive ,residential development: The ;architectural plans show A. use of materials that would, be 42 harmonious with the area, and the preliminary, landscape plan proposes a. variety of trees, shrubs 43 vines and groundcover that would enhance the streetscap.e, parks, pathways ; and :entry areas, 44 including a generous landscaped area proposed at the corner: of Frates Road and Lakeville 45 Highway. However, the sound wall that ,is proposed to run along Lakeville Highway and Frates 46 Road would dominate public views oft project site. Furthermore, given that this site is located 47 at the gateway to the City, a 10 -12 foot high sound wall,. even with landscaping, may not be a Page 4 I desirable entry to the City of Petaluma. As discussed further below under project issues, staff • 2 recommends that the Planning Commission provide the applicant direction on how the project 3 should be.. modified to reduce'the height, or eliminate the need for a 10 to 12 -foot noise barrier so 4 that views of the surrounding lands and Bills can be maintained to a greater extent. 5 6 Policy 27 - The City shall ,require the provisions of privately owned open space in residential 7 developments of more than 15 units where made necessary by project density or design, or lack or 8 proximity to public parks and open space.. 9 10 The applicant proposes'that the 1.34 -acre central park and the small island in the street (Lot A) 11 be dedicated to ,the City, and that 4.6 =acre open space along the southern boundary be privately 12 owned. and publicly accessible. The combination of both public • and private open space, totaling 13 more than, six acres, attempts to respond to the goal of the General Plan to provide open space 14 and useable recreational areas. It should be noted that Urban Separator lands in other parts of the 15 City have been dedicated to the City as open space and not held' privately. 16 17 Land Use and Growth Management Element 18 19 Policy 12 — The Urban Separator.shall continue to serve its function as a continuous chain of open 20 space on the East Side, while being intermittent on the West side. 21 22 Policy 14 — The City shall extend the length of the Urban Sep_ arator where feasible, at a maximum 23 width of 300 feet. 4 25 Policy 18 — Details of public access, pathways along the entire 'length of the Urban Separator shall 26 be established during the development review process, in concert with project design. 27 28 A band of the Urban Separator followed by the Urban, Growth Boundary follows the east 29 property line (along Ely Road) and the south property line (adjacent to County agricultural lands) 30 of the subject property. The General Plan describes the Urban. Separator as a visible band of 31 open space that marks the, edge: of allowable development. It is continuous on the east side, 32 intermittent on the west side and runs adjacent to the Urban Limit Line for most of its length. 33 The Urban Separator provides an edge that buffers farmland from urban land'. It can serve as a 34 recreation area and a key component of the City's open space' system. It prevents urban 35- development from extending; unchecked into surrounding open space,, since private development 36 cannot take;place within the, separator. 37 38 Along Ely Boulevard '(east boundary) where the Urban Separator is indicated on. the. General Plan 39 Land Use Map, the Southgate Development Plan proposes single= family homes, and a 20 -foot 40 wide landscaped area between the current edge 'of pavement and the rear- lot fencing. Proposed 41 conditions approval would require the applicant to construct % street improvements along the 42 entire Ely Road project frontage; including but not limited to: 'pavement construction and 43 reconstruction to provide for a 1.2 -foot travel lane, curb, gutter, sidewalk, striping, streetlights, 44 six -foot wide bike lane, fi_re hydrants and landscaping. Additional improvements would be 45 necessary at the intersection of Frates Road to provide for both turn lanes and through lanes. Page 5 I Along the southern site boundary where the Urban. Separator also exists', the Southgate plan shows 2 a 120 -foot wide, passive open space area, including °the proposed detention pond's, which is • 3 entirely within the existing ,120 -foot wide PG &E transmission easement, This .area, which totals 4 approximately 4.5 acres, is proposed to be privately, owned but accessible to the public. 5 6 The Land Use Map of the General Plan depicts the Urban, Separator as a, uniform width along the 7 north and east property lines. However, .General Plan, objectives related to 'the Urban Separator 8 indicate that the Urban Separator shall be a .maximum of 3.00 feet except in those areas where it 9 may be variable, or is already established at more than 300 feet, neither of are the case for 10 the subject property; Whi -le General, Plan policies appear to allow for some. flexibility in the width 11 of the Urban. Separator the City'has consistently required a 300 -foot wide Urban Separator along 12 the eastern City limits. In addition, one of the stated objectives under the discussion of the Urban 13 Separator in the, General Plan ;is to "[C]continue to' require dedication of open space. lands ;in the 14 Urban Separator as -a condition of development within the City limits." (Objective (i)) 15 16 The applicant has 'indicated that= the 20-foot landscape area along the eastern edge (Ely Road) and 17 the 120 -foot wide open ,space /detention area along the southern edge are intended to provide 18 pedestrian and bicycle access along the; edges of the site consistent with the objectives of the 1.9 General `Plan Urban Separator. The applicant notes that the area along the south, side• of the site 20 provides the ;greatest opportunity for an open space experience, given the agricultural uses 21 immediately to the south. of the site. As noted further below under project issues, staff ' seeks 22 direction. from the Planning Commission regarding the project's conformance with general plan 23 policies regarding the Urban Separator. 24. 25 Policy 23'- Convenience . shopping in proximity to residential shall be encouraged :. 26 27 The project does not propose any retail or commercial uses, and there is. _no xetail (shopping) use 28 near the ; project site. Furthermore,, the site is separated from retail locations by major arterials, 29 which make access for seniors and youths more difficult. Given the lack of retail uses ins the area, 30 staff recommends; that the applicant be encouraged to consider a modest, neighborhood - serving 31 retail use that would serve Southgate residents, the :future affordable housing, facility and adjacent 32 neighborhoods and workers. While staff is aware that some neighbors were concerned about the 33 amount of,' development contemplated by the previous proposals for the site, it is staff's opinion 34 that neighborhood serving-retail use (in the 20,000 to 30,000 square foot: range) is appropriate to 35 consider in light,of this general plan policy. This issue is discussed further under the Project Issues 36 section of this report. 37 38 Policy 28 - ' The -City shall support residential development only in those areas inhere adequate 39 City facilities are available or will be provided with development: 40 41 Conditions to, ensure that adequate City services will be imposed at the appropriate ,stages of the 42 project entitlement and _building permit review process. Comments from various City 43 departments are included as Attachment E to this report. 44 45 46 • • Page 6 1 , • 2 Open Space, Conservation, and Energy Element 3 4 Policy 25 - Developers shall provide adequate drainage and erosion control during 5 construction. 6 7 1 The developer will be required to conform to City and State regulations by providing an erosion 8 control and storm water pollution prevention plan, which shall be adhered to throughout project 9 construction. 1' 0 11 Park and Recreation Element . 12 13 Policy 5 - The city should provide park sites to respond`to the needs of a diverse population. The 14 needs include creek side systems; trail ways for pedestrians, joggers and bicyclists, and non - 15 traditional' types of recreation such as habitat restoration projects, community gardens, and 16 skateboarding. 17 18 The Southgate development plan proposes a 1.34 -acre central park (proposed to be dedicated to 19 the City as a public park) and an open space area along the southern property line (to be held as 20 private property but made open to the, public as a passive recreational area). These open space 21 areas would provide an ,opportunity for,passive and active recreational uses. However, Planning 22 staff is not aware that the opportunity for °organized recreational uses such, as soccer, baseball or 3 softball, have been evaluated by the City's Park & Recreation Department. The applicant has 4 indicated that details of the recreational and open spaces will be submitted as part of a 25 .subsequent. Site Plan and Architectural Review packet following Vesting Tentative Map 26 approval. 27 28 Community Health and'Safety (Chapter 11) 29 30 Policy 25 — Strictly enforce local noise standards. 31 32 The Community Health and Safety Chapter of Petaluma General Plan, which includes the State 33 mandated Noise Element; establishes acceptable noise levels for different land uses. For the 34 purpose of assessing, noise impacts associated with the proposed project, an interior noise level 35 of La 45, and an Ld for exterior use areas in'single- family residential development were used 36 as the si gni esholds. As explained in Noise Section of the Initial Study (Attachment ifcanoe thr, 37 C), this is with the criteria contained in Appendix G of the CEQA Guidelines. 38 39 A. Noise Mitigation Study prepared by the applicant's consultant, Rosen Goldberg & Der 40 Acoustical Consultants',, assumed the construction of a 10 to 12 -foot tall noise barrier along 41 Frates Road and.Lak'eville Highway. The noise study concluded that even with the noise wall, 42 future noise, levels in the backyards of 45 of the proposed lots adjacent to Lakeville Highway and 43 Frates Road are , expected to bel Ldn 60 to '64 dBA. This would result in noise levels 0 to 4 dB 44 above the significance' threshold for exterior noise levels established by the City's General Plan 45 policies. ,Based on the thresholds used in the Initial study, this would be considered a significant �6 environmental. impact. To reduce or avoid this impact, the Initial Study includes a mitigation Page 7 I measure which requires `that project revisions and modifications necessary to conform to 2 residential noise standards be reflected on plans submitted for review and approval by the City of • 3 Petaluma. Staff recommends that ;the Planning Commission provide the applicant direction on 4 how the project should'' be,modified in order to be consistent with General Plan Policies.. 6 It should. be noted that the Noise Mitigation Study characterizes the interior Ldn 45 and exterior 7 Ldn 60 :noise, levels referenced in the City's General, Plan as "goals" rather than standards. In 8 addition, the study also references Caltrans', noise abatement criterion, If the: City of Petaluma 9 general plan did not specify any noisestandards, it might: be appropriate to consider the Caltrans 10 noise abatement criteria. However, that is not, the case. The, study further points out that 11 although.. the Ldn for these 45 homes is up to 4 dB above the City's outdoor ``goal' ; a 3dB 12 increase in noise levels is considered a just noticeable difference, while °a 5 dB change, is clearly 13 noticeable but not dramatic. Nevertheless, absent any clear policy by the City of Petaluma that 14 points to a different. interpretation of the general plan noise standards, staff considers the interior 15 Ldn 45 and exterior Ldn 60 noise levels referenced in the City's General Plan to be the ;most 1 appropriate thresholds for assessing noise impacts, in accordance with CEQA criteria. 17 18 The proposed sound wall and adhere_ nce to the General Plan noise standards is discussed. further 19 under Project' Issues.. 20 21 General Plan AmendmentReq_uest 22 In ordeuto approve a :General Plan Amendment, the, following findings must be made: 23 prop 25 � General Plan and an Gener implementation lement tion Am t and co with the rest of the y p p g rams that may be affected. 26 '27 ® Potential impacts of -the proposed amendment have been assessed and have been 28 determined not to be detrimental to the public health, safety, or welfare. 29 30 ® The proposed amendment has been processed in accordance with the applicable 31 provisions of the California Government, Code and the California Environmental Quality 32 Act (CEQA). 33 34 As discussed above; the project as `currently_ proposed. would not conform, to General Plan noise 35 standards. In addition, staff has raised other issues, such as a idesife to provide some 36 neighborhood- serving:retail, as part ofthe project that-woul_d require.a land use:designation other 37 than "Urban Diversified ". Therefore, staff recommen6 that the Planning Commission provide. 38 direction to staff and the applicant on 'how the project should be modf ed in order to be 39 consistent with General Plan. Policies. 40 41 Zoning Distrief Corisisteney 42 The;. proposed rezoning would replaceahe existing "Study District" with a Planned Unit ,District 43 (PUD).. The current "Study District" was applied to the property 'at the time the property was 44 ann exed into the City in "1,985 along with, the Adobe Creek Golf and Country Club located 45 northeast ,of the project site. The purpose of the Study District is to provide ;a means to permit 46 the study of appropriate future zoning in order that no actions. can be: taken during' the study C • Page 8 i I period, which might be prejudicial to the proper future development of the property. As noted • 2 previously, the site ha& been considered for residential development, a community college 3 campus, and an elementary or junior high school site, a business park and amixed -use project. 4 However, the Study District designation remains as the current zoning for the site. 5 6 The proposed Planned Unit District is intended to allow a mixture of uses, or unusual density, 7 building intensity, or design characteristics which would not normally be permitted in a single 8 use district. Application of the creation of a PUD is required to be accompanied by a Unit 9 Development Plan. In recommending approval of such a plan, the. Commission must find that 10 the Plan clearly results in a more desirable use of land and a better physical environment than 11 would be possible under any single zoning district combination of zoning districts. The City 12 Council may approve the PUD with a recommendation from the Planning Commission based on 13 a series of findings (Article ° 1,9A, Section 19A -300 City of Petaluma Zoning Ordinance). These 14 findings include: 15 16 e The PUD provides fora suitable relationship to one or more thoroughfares with adequate 17 capacity to carry any additional traffic ,generated by the development; 1.8 ® The development would result in a unified and organized arrangement of buildings, facilities, 19 and landscaping to ensure -compatibility with nearby properties; 20 o The natural and, scenic u" q alrties of the site are protected', with adequate available public and 21 private spaces; and 22 • Development of the property will not be detrimental to the public welfare and will be in 23 keeping with the general intent of the Petaluma General Plan; the Zoning Ordinance, and 0 4 other applicable plans adopted by the City. 25 26 Single Family Homes. The applicant has submitted proposed Development Standards as part of 27 the Unit Development Plan. (Attachment G) which specify three different lot widths for the 28 single- family lots: 45 feet; 55 feet and 60 feet. For each Lot Width Type, 4 to 5 different home 29 floor plans have been submitted, with three different architectural treatments for each floor plan. 30 The applicant has indicated that the architectural, styles for the homes, Craftsman, Victorian 31 Farmhouse and Italianate, focus on Petaluma History. The following yard setback requirements 32 are proposed, with certain encroachments for porches, bays, chimneys, etc. permitted: 33 34 Front Yard Setback - 15 feet 35 Side Yard Setbacks.— 5 feet/10 feet 36 Rear Yard Setback - T0; feet 37 38 The development standards stipulate'a 32 -foot height limit- for all single -- family residences, and 39 that each single; family home shall have a minimum .of a two -car garage served by a 20 -foot long 40 driveway,. allowing :for ,spaces on the driveway. Many of the homes feature front 41 porches and an emphasis has been 'placed on "pushing back the garage door from the front 42 house elevations; on some lots, the garage is set back over 40 feet from the front building 43 elevation. 44 45 Future Affordable Dousing. The 3'.04 -acre site labeled Parcel B on the Vesting Tentative 0 6 Subdivision Map is reserved for a future affordable housing development. The total number of Page 9 I units permitted. for the site shall be between 25 and 80. No, site or architectural plans have been 3 b the a f �lcant u establsh r manimum s buildin We and landsca Development Standards submitted 0 P g; , y pp g p setbacks, as well as maximum 4 building height limits. 6 Project Issues: 7 8 The significant issues presented by the Southgate proposal include the following: 10 a Urban Separator 11 ® Proposed Sound Wall /Genera.l Plan Noise Standards 12 ® Grading 13 • Vehicular,Access /.Control and Circulation %Pedestrian Safety 14 Y Proposed Land Uses 15 16 These. issues are discussed further below, along with staff recommendations, 17 18 Urban Separator. This issue is discussed under General Plan Consistency. As -proposed; the 19 project does not, provide for a 300 -foot Urban ,Separator. While General Plan_ policies appear to 20 allow for some flexibility in width of the Urban Separator, the. City has consistently required a 21 300 -foot wide Urban .Separator along the eastern City 'limits. The applicant has indicated that the 22 20 7foot landscape, area along the eastern edge (Ely Road) and the 12'0 -foot wide open 23 space /detention area along the :southern edge are 'intended to provide pedestrian ;and bicycle 24 access along the edges of the site consistent with the, objectives of the General Plan Urban 25 Separator, The ,Planning, Commission, should determine whether the project; as proposed and 26 conditioned, would meet the intent of the General Plan objectives regarding the Urban Separator. 27 Specifically, the Planning Commission should consider the following: 28 29 ® Consider whether the proposed 20 -foot wide landscape buffer proposed along Ely .Road, and the 30 120400t wide.PG &E easement along the southern property boundary would provide an adequate 31 Urban, Separator. 32 33 o If appropriate; provide direction on modifications to the development plan in order to provide for 34 an adequate Urban Separator. 35 36 Proposed Sound Wall Plan Noise Standards 37 As discussed above, a Noise Mitigation. Study prepared by the applicant's consultant, concludes 38 that even with a 10, to 12 46ot tall noise barrier along Frates Road and Lakeville Eighway, 'future 39 noise levels in the; backyards of 45 of the 221 lots adjacent to Lakeville Highway and Frates 40 Road are expected to be Ldn 60 to 64 dBA. This would result in. noise levels 0 to 4 dB above the 41 significance threshold, for exterior noise levels established by the City's General Plan policies. 42 To avoid this impact, the Initial 'Study includes a mitigation measure which requires that all 43 residential uses conform to the. Ldn 45 (interior) and Ldn 60 (exterior use areas) noise standards 44 established in the City of Petaluma General :Plan, and requires that' project revisions and 45 modifications necessary to conform to residential _noise standards shall be reflected on plans 46` submitted for review and approval by the City of Petaluma. Staff recommends that the Planning • Page L`0 h General Plan Policies. Given that this site is located at the di in order C y , 2 consistent wi • I Commission provide the a licant direction on how the project should be modi gateway to the City, 3 staff also seeks direction from the Commission on the desirability, from a visual and aesthetic 4 perspective, of a .10 -12 foot high souindwall along Lakeville Highway and Frates Road. 5 6 Grading. Engineering plans submitted for the Southgate project indicate that fill areas up to 7.5 7 feet in depth are proposed in the Southwest corner of the property adjacent to the lowest 8 detention pond. Since no encroachment into the Lakeville Highway . right -of -way is indicated, a 9 7.5 -foot high retaining wall would be required at this corner would be necessary to retain the 10 proposed fill area. Such a retaining wall, combined with a 10 to 12 -foot sound wall would create 11 a wall as high as 19.5 feet along Lakeville Highway. It is staff's understanding that the applicant 12 is revising the grading plan to address this concern; however, a revised grading plan has not been 13 reviewed by staff. 14 15 Vehicular Access. Mitigation measures are identified in the Initial Study (Attachment C) and 16 included in proposed Conditions of Approval that would .ensure acceptable levels of service (LOS 17 D) at all intersections within the project area. Under cumulative traffic conditions this project 18 would result in LOS E at the new intersections created'to serve this project. To reduce this impact 19 to an acceptable level, mitigation measures have been included that require the installation of 20 traffic signals at °the following intersectionsf 21 22 o Frates Road and Calle Ranchero (project entrance) 23 o Frates Road and Lakeville Circle (project entrance) &4 o Frates Road and South Ely Boulevard/Ely Road 25 o Frates and Adobe Road (applicant would provide a fair share contribution to a future 26 County signalization project) 27 28 It should be noted that even though the 'traffic study for the project indicates that future traffic 29 conditions at the two proposed project entrances on Frates - Road (intersections at Calle Ranchero 30 and Lakeville Circle) would not meet the peak hour signal warrant criteria, a traffic signals 31 would be required to maintain acceptable .peak ;hour LOS D. It should also be noted that 32 signals at these locations will allow controlled access from the site to bicycle and pedestrian 33 traffic, particularly to students of nearby schools. 34 35 Staff also suggests that the Commission consider directing, the applicant to eliminate the 36 Lakeville Circle/,Frates� Road entrance to the project in favor of a new entrance off Ely Road, 37 approximately in the- ,location of Lots 199 and 20,0. A proposed :condition of approval would 38 require this segment of Ely Road to be improved to City Street Standards, and a mitigation 39 measure' identified in "the Draft Initial Study would require that the Frates Road /South Ely 40 Blvd /Ely Road intersection be signalized. Therefore,, a new access point on Ely Road would 41 serve to eliminate the need for a new signalized intersection at Frates Road and Lakeville 42 Circle, and would channel traffic from the project onto a relatively low -use street with 43 signalized access at the Frates Road /South Ely Blvd /Ely Road intersection. 44 45 Lastly, staff recommend's eliminating the two roads that dead end into the proposed Urban Separator nearaots�96 /135 and. lots 159/179. It is doubtful that these stubbed out roads will ever Page 11 I be extended. If an expansion. of the Urban Growth boundary should. occur in the future, this 2 area would be adequately served by Ely Road. • 3 4 Proposed Land Uses 5 This site constitutes one of the last remaining large, easily developable tracts of land in the City 6 of Petaluma. As reported. earlier-- many ideas and projects have been proposed for this site 7 without success. Given the existence of the Urban Growth Boundary and the fact that the City is 8 approaching build out within that boundary, it appears that this site offers a unique opportunity to 9 the City and the applicant to establish a development that incorporates some, :if not all, of the to elements of ;Smart. Growth, specifically a - design that yrovides. a mixture ofiuses that_ will serve 11 the new neighborhood and reduce the need for additional automobile trips. To their credit, the 12 applicant has proposed a mixed -use project in thel past that was ultimately determined to be too 13 intense by the adjacent neighborhood and the City Council. Staff seeks direction from ' the 14 Planning Commission as to whether some compromise plan could be developed that can satisfy 15 the interests of the neighborhood and result in utilizing this land in a more efficient manner. 16 17 Bicycle Committee Recommendations: 18 In March. 2000, the City Council adopted. the City of Petaluma Bicycle Plan and Map as, an 19. amendment to the City's General Plan Circulation Element. The Plan states that..the .City shall 20 route development plans to the Petaluma Bicycle Advisory Committee (PBAC) in a timely 21 fashion, allowing consideration of'bicycle /pedestrian issues. A proposed condition of requires 22 all phases of'the project to be reviewed by PBAC to ensure conformance with the. Bicycle Plan. 23 24 PUBLIC NOTICE AND COMMENT 25 26 A notice of public hearing was published in the Argus Courier, and notices were sent to: residents 27 and property owners within 500 feet of the subject property. Additional notices were mailed'to 28 residents of the Calle Ranchero and Adobe Creek neighborhoods. As of the writing,if this.report, 29 staff has not received any written correspondence from members. of the public. 30 31 ENVIRONMENT, AL REVIEW! 32 33 Pursuant to the requirements of the California Environmental Quality Act (CEQA), an Initial 34 Study .of potential environmental impacts was prepared (see Attachment C). The potential for 35 the following significant impacts .were;identifi'ed`: temporary geology & soils, air, hydrology & 36 water :quality; noise, visual quality & aesthetics and transportation/traffic. Mit'igati'on measures 37 would need to be agreed to by the applicant to ensure that potential impacts would be reduced to 38 less than; significant.

The materials already distributed to the Commission on the project as part 3 of the December 9th packet are still relevant and should be retained for this meeting. 24 25 The following is a summary of the attached materials. 26 27 . Memo from the Petaluma Pedestrian and. Bicycle Committee 28 29 This memo, provided to staff on December 4, 2003„ contains preliminary recommendations 30 from the PBAC on the; Southgate °project. It is staff's understanding the PBAC was awaiting 31 the submittal of a circulation plan before finalizing their recommendations on the Southgate 32 proposal. A circulation plan was "not provided in the initial plans submitted by the applicant. 33 However, plans submitted for the Planning. Commission packet did include a sheet entitled 34 "Circulation Plan" and a copy has been provided to PBAC. Therefore, the attached PBAC 35 recommendations should be viewed as preliminary. 36 37 ® Letter from Basin Street Properties 38 39 This letter from Vin Smith of Basin Street Properties, dated December 9, 2003, addresses a 40 number of issues raised in the staff report and Draft Initial' Study. The letter focuses on 41 proposed changes to the project, including an alternative site plan that has been prepared in 42 an effort to address the concerns raised by staff. 43 4 ATTACHMENT 4 Page 1 2 • Annotated List of Draft Conditions 3 4 As explained in the attached letter, the applicant has submitted an annotated list of conditions 5 of approval, which indicates those conditions the applicant accept, those that they wish to 6 conditionally accept with suggested modifications, and those conditions that, the applicant 7 does not accept. 8 9 • Revised Noise Mitigation Study 10 11 The applicant has submitted a revised Noise Mitigation Study, which assesses the noise 12 mitigation associated with the alternative site plan. While staff has not reviewed the 13 alternative site plan or the noise study in detail, based on a quick review, it appears that. the 14 height of proposed noise barriers have been reduced to six to 10 -feet tall, rather than the 10 to 15 12 -foot heights initially proposed. This is due to the changes proposed by the alternative site 16 plan, which locates a frontage road between the adjacent roadways and the homes. This in 17 turn would allow the homes themselves to act as noise barriers and reduce noise levels in the 18 rear yard area. 19 20 • Alternative Site Plan 21 22 An alternate site plan has been submitted which proposes a number of changes, as outlined in 23 the,attached letter from Basin Street. 24 25 Note: Staff has not reviewed the letter, proposed project changes or any of the other 26 attached information submitted by Basin Street Properties in any detail, given that it 27 was received shortly before this packets was distributed. 28 29 ATTACHMENTS 30 '31 A.

The proposed park as reflected on the developer's submittal is comprised of parcel "C," which is 1.08 acres in size -In order to approach the developer's specified 1.34 -acre park, and to follow the long standing planning principle of the Recreation, Music and Parks Commission of no houses backing onto a park, the proposed park °is to include parcel "C" and the area now designated as lots 218 -221. (A total of 1.32 — acres) 2. The proposed park is to ,have a large ,community playground, for pre- school and youth aged children, as specified by the Parks and Recreation Department. The playground is to be located within'the park as determined by the Parks and Recreation Department. 3. The Urban Separator is, recognized a$,beingl as compared to the 300' width required lin a majority of areas along the east!'side of Petaluma. Regardless of what the Planning Commission should decide the size of the Urban Separator should be, a bicycle / pedestrian path is to be. constructed, running the entire length of the urban separator. The path is to connect to the sidewalk running along Ely Road, travel southwest, towards Lakeville, and be connected to the subdivision at two locations equidistant. The two reflected streets dead- ending into,theUrban Separator would be locations for side access points to the path. The path is to have benches and'trash receptacles, consistent with other east -side separator paths. 4. The proposed Urban Separator, despite the size (as determined by the Planning Commission) is to be owned "fee title" by the City of Petaluma. • Cc Mike Bierman, City Manager ATTAC H M aM_r 6 Ed Anchordoguy, Parks and Landscape Manager WNW, Ge6rge_, m: Carr, Jim W o: t: Thursday;.

The playground planned for the proposed park be on the same scale as the playground designed for the new Gatti Park, and meet with the approval of the.Recreation, Music.and. Parks 2. The developer is to providean annuity to cover annual maintenance of the park (approximately $10,000 per year). 3. The bike / pedestrian path located in the urban separator currently terminates in a turn around at the south- west edge of the property. The path is to connect to the residential street that parallels. Lakeville Highway, possibly traversing between parcel 33 and the proposed sound wall. 4. All landscape maintenance on Frates Road, Ely Road, Lakeville Highway and in the urban separator is to be maintained through a landscape assessment district.

Revised Vesting' Tentative Map The key changes: from the prior plan are the _ munity park to abut the nature; park, the addition of access to the project via'S. El Y Boulevard, the enlargement of the.gateway entry treatment at the corner of Lakeville Highway and Frates Road,, the enlargement of the urban separator along S. Ely Boulevard, and the enlargement of the landscape treatment between the soundwall and the public right of way on Lakeville Highway. 2. Revised Site Development. Plan 'The;key change from the prior plan is the increase in rear yardsto a minimum of20 feet, with the exception of four homes having rear yards of 16 feet. 3. Traffic Study Addendum This addendum to the original Traffic Study analyzes various access and control alternatives, including the new project access via S. Ely Boulevard. 4. Revised PUD Development_ Standards The key changes, from the prior standards are the increase in rear yard set backs -,to 20 Teet and the narrowing of permitted uses on the PEP site to senior /disabled housing. -5. Revised - Comments to Recommended Conditions of Approval These comments on ,the- staff'recommended conditions of approval were revised to reflect the niater'ials submitted with this letter. 6. Noise Study Addendum This addendum to the original Noise Study updates the prior report by taking into account the relocation of sound walls as .directed by the Planning Commission, and also provides the sound data requested by the Planning Commission for the, homes closest to Lakeville Highway and Frates Road. Yesterday we received a copy of Ms. Allsep's Memorandum provided to you on January 29, 2004, a copy of which is'att'ached to this letter as Exhibit A . As discussed in greater detail below, CA W%VK'-1:A I IN -S T'M :. '.l (iit ATTACHMENT 8 February 6, 2004 Page 2 - 6` BASINSTREET we believe we.have addressed all of the issues raised in the - memorandum. For your convenience -our discussion follows the same ordering and numbering used in the memorandum. 1. GatewayjNoise Barrier /Aesthetic Issues a.' The. southwest corner has been modified to delete two lots and modify`the roadway. Approximately. 560 linear feet of soundwall has been_ removed and.: the corner "'Gateway Parcel" at Frates and Lakeville has been increased to 1.35 acres. b. A 1.35 acre parcel has been created for a landscape gateway element at the Lakeville /Frates Road intersection. The revised conceptual landscape plan for the entire project, including the 135 acre gateway component, will be provided in a supplemental submittal by Friday, February 13` c:. As noted above approximately 560 linear feet of soundwall has been eliminated as a,Tesult of the modified design. d. At the Planning Commission. Meeting, :Basin. Street Properties agreed to contribute funds to the ultimate de.sign,and installation of a "Gateway `Element" to be located within the Urban Separator adjacent to Lakeville Highway. e. The project roadway parallel with. Lakeville Highway has been modified and located such that eight (8) feet of landscaping will be provided between the project' boundary and the new sound wall. f. An.addendum to the original noise study is attached to this letter: The addendum, includes.hard 'data for the homes fronting Lakeville Highway and Frates Road. Such data shows that all useable rear yards will not exceed the General Plan .guideline 'of 60 dBa Ldn. 2. Public Park (Jim Carr memo) a. At the direction. of the Planning Commission, the public park'has been relocated to be adjacent to and integrated into the Urban Separator. The revised conceptual landscape plan for the entire project, including the neighborhood' park, component, will be provided in a supplemental submittal by Fridaay,. February 13 ` b. The revised plan does not include: any lots backing up to the relocated- neighborhood park '(one lot has a side yard abutting the park).. 3. Urban Se.parator/Feathering a The Urban.Separator between the pro'' boundary and the travel way along'S. Ely Boulevard has, been increased from 20 -2=5 feet to 36 -41 feet. The revised conceptual landscape plan for the entire project, including the landscaping and "natural" trail within this 36-41 foot wide area.componerit, will be provided in a supplemental submittal by Friday, February 13` b. At the direction of 'the, Planning'Comrn ssion, the public park has been relocated to connect to the Urban Separator. 4. Setbacks/Development Standards a. All lots within the development now provide minimum 20'.foot rear, yards except that Lots 89; through 92 provide 16 foot rear yards. A' si a result of compliance with, the expanded rear yard setback,and in an effort to create .an attractive street February 6, 2004 •''� 0, ) Page 3 BASINSTREET frontage, ,Lots 1, 40 46, 47, 511, 57, 58 and 210 have minor front yard and /or side yard encroachments. b. At the direction of the Planning. Commission, (i) the rear yard setbacks have been increased to 20 feet '(ii) the exceptions to the rear yard setbacks have been deleted, and (iii) an allowance for encroachment of porches into the front yard setback of up to seven feet has been added. Access /Circulation a. Basin Street Properties proposes to install half - street frontage improvements on Ely ;Blvd. from `Frates Road to the new project access. b. At the direction of the Planning Commission, project access from Ely Blvd. is now shown. 6. PEP Housing Site a. The PUD Develgpinent Standards have been modified to require approval of a Conditional Use Permitby the `Planning Commission and Site Plan and Architectural Review Committee approval prior to development of the Senior /Disabled housing site. 7. Land Use /Smart Growth, Principles a. As noted in Ms'. Allsep's memorandum, the Planning Commission did not recommend pursuing a retail component for the project. 8. Maintenance of Infrastructure within Subdivision a. We believe thatthe City of'Petaluma's longstanding policy of accepting the dedication of public streets within subdivisions is appropriate and reflects standard practice among municipalities. , Included in Ms. Allsep's memorandum is a discussion of CEQA and a perceived need to modify the Initial Study. Ordinarily, aft Initial :Study would notbe modified to reflect project modifications. Instead, the mitigated negative declaration would be modified upon project approval to reflect •project modifications and changes in mitigatiori measures. While it would not be improper for City staff to make, draft revisions to, the mitigated negative declaration at this time, CEQAAoes not require this, and the modifications can instead be directed by the City Council at the time of project approval. Finally, Ms. Allsep's memorandum requested the following',addiiional items listed in italics. Following each item is a discussion of the item requested. • A complete, etc. By Friday the 13` e will be submitting a revised grading ,lete, set o laps or the revised ro'ect, including civil drawings, street ng and utility °plan revised architectural sheets, and a revised conceptual landscape plan. • Revised, PDP'Development Standards. The Planned Unit Development Standards have been revised—according to the.Planning Commission direction. Revised Traffic :Stud_ y. An addendum to the original Traffic Study prepared by Dowling Associates • Inc. is provided with this letter. The study analyzes the .proposed changes to Frates Road. and the, new project access from Ely Blvd. The PUD Development Standards have ,been modified to reserve the affordable housing site strictly for Senior /Disabled affordable housing.

Further, it is my understanding that it is the Planning Commission's expectation that the "design change" consensus items be. incorporated into project that is presented to the City Council. 1. Gateway/Noise Barrier /Aesthetic Issues — The site serves as a gateway to the City. Noise wall along the road,, as "proposed, is not an appropriate gateway. a. Fix the "problem corner" near Frates and Lakeville by reconfiguring the awkward lots in that corner. Okay to relocate lots elsewhere on site to maintain same unit count for single - family homes. b. Create a landscaped "Gateway" element at Frates /Lakeville corner. c. Tie above redesign would allow the length of the noise wall along Lakeville to be substantially reduced. d. Create "Gateway" element at other end of Lakeville noise wall, near PG &E easementlUrban *,Separator. e. Provide for wider planting area along the outside of the wall, (toward Lakeville).. The proposed two -foot wide planting area is not adequate. The noise study shall include hard data (not just conclusion), which demonstrates that project, conforms to General Plan noise standards for residential development: 2. Public Park (Jim Carr memo) a. Relocate park to connect to Urban Separator /PG &E easement, per Urban Separator discussion. b. Eliminate lots backing up to park. 41 Urban Separator/Feathering • a. Decrease the lot dimensions in order to increase setback (Urban' Separator) along Ely`Road. b.. Relocate park adjacent to PG &E easement /passive open space to provide more useful open `space area/Urban;S'eparator. 4. Setbacks /Development Standards a. Amend Development Standards to provide for a minimum 20 -foot rear yard setback, except, for lots with rear yards that back 'up 'to. Urban Separator, which should have a. minimuin rear yard of 15 feet. b.. Delete exceptions to ,minimum setbacks in Development Standards (shown in superscript). 5. Access /Circulation a. Per Craig Spaulding, Municipal Code requires frontage 'improvements along public streets. Improvements to Ely required as condition of project approval' whether or ,not access on Ely, is proposed. b. Access from Ely Road should be considered if it helps to mitigate traffic issues on Frates, .improves pedestrian safety and provides for traffic calming measures. PEE Housing -Site — Planning Commission supports the 'PEP project. 100%, but is not comfortable with lack of:any information on. the development of the site, a.. Condition requiring that PEP site subject to CUP requiring PC approval and S'PARC approval. Land Use /Smart Growth `Prineipl'es While some members of the PC. were interested in considering a retail, land use-component on the site that could help resolve noise wall /gateway ,issues as well' the issue was not pursued given the neighbor'opposition to any retail and the history of this site /project. 8. Ma►ntenance of Infrastructure within Subdivision – It was the consensus of the Planning Commission that this is a ,citywide policy issue that should be. addressed byahe.City Council. In addition, to tle• °project - related issues noted above, the Planning Commission raised One process - related issue related to environmental ,review.. It was °ihe consensus of the Planning Commission that the Initial Study, which, serves as the CEQA document for the project, shouldbe revised to reflect the revised project that will be presented to, the City Council I agree that the Initial Study should bey revised and reco ilmend. that the applicant provide the information necessary to coniplete the revisions to the. Initial Study, as outlined below: is 2 A complete set of plans for the revised project, including civil drawings street sections, a landscape plan, etc. • Revised PDP `Development Standards that reflect Planning Commission recommendations regarding setbacks, Use Permit for PEP site, and any other changes necessitated by the revised project design. A revised. Traffic Study that addresses the revised project, including changes to access and .internal circulation. In addition, ITE trip generation rates referenced for the PEP housing site should be consistent with the use designated in the, PDP development standards, which is affordable housing, not senior housing. Vin Smith. revised project description to delete "Senior" housing from ,project description and development standards, and as you know, senior housing typically has a lower trip generation rate. While the difference nmy.not be significant, the traffic study should use the appropriate trip generation rate. ® A revised Noise Study that includes the following: o An analysis which demonstrates that the specified placement and height of the proposed noise wall- (based on redesign discussed above) will provide the mitigation necessary to comply with General Plan noise standards for residential development. o Noise contours for future noise levels along Frates and Lakeville, as is typically provided in. a noise ; study for residential subdivisions. This will provide the Bard data requested by the Planning Commission. o Reference to the traffic study /data used to determine future noise levels, including the percentage of -truck traffic assumed for future traffic volumes. Truck traffic can have a substantial effect on traffic noise levels. Please note that I prepared this memo based on my notes, without the benefit of reviewing any meeting ;minutes or the videotape. Perhaps we should discuss and compare notes to ensure, accuracy and completeness of Planning Commission consensus items.

Dowling.Associates Inc. conducted the background:and traffic impact assessment for the Southgate 2 project in Petaluma, California. We have been asked to evaluate the impact of a series of proposed mitigation measures suggested by the City Council. Candidate Mitigation Measures The basic mitigation measures include: 1. Construction a signal at Frates Road and Calle Ranchero 2, Providing all- way (four -way) stop controls at Frates Road and South Ely Road. 3. Maintainirig the existing stop controls at Frates Road and Lakeville Circle with stop controls installed on the exit from the Southgate 2 project across the street from :Lakeville Circle. Additional mitigation measures have been suggested by Basin Street properties, which include: 1. Providing a new access from the Southgate 2 project onto South Ely Road to the south of .Frates Road. 2. Restricting the outbound left turn movements from the project at Lakeville, Circle. Analysis of Alternatives! Three analysis intersections were added to. the Citywide Synchro traffic model for the PM peak . hour cumulative. condition: Calle Ranchero /Frates Road, Lakeville Circle /Frates Road, and South Ely Road/Frates Road. Cumulative traffic projections from the Southgate 2 traffic assessment were imported into the model for analysis. The detailed.'levels of service calculation sheets from the Synchro model are available upon request. Table 1 shows the impacts of the candidate mitigation measures. For all alternatives, the PM peak, hour is the critical time period for the corridor and project impacts. With the. installation of a signal at Frates Road and `Calle Ranchero, :level of service B :(10.1 seconds per vehicle of delay) is maintained under all options. When the existing stop controls are maintained at Frates.Road and Lakeville Circle; level of service E (42.9) occurs, If a new access is provided from the project to.South Ely Road the level of service at Lakeville Circle is improved to D' (32.0). It ,is assumed that 50 percent of the trips • 180 Grand Avenue - Suite.250 . Oakland, CA 94612 (510) 839 -1742 .

If the exiting left turn movement from the project entrance at Lakeville Circle onto Frates Road is,restricted, the level of service at the Lakeville Circle intersection improves to C (15.5). Further, LOS C is maintained at Frates Road and South °Ely Road and LOS B is maintained at Frates Road and Calle Ranchero..For'this option, it is assumed that no left turn traffic would be allowed to exit the project at Lakeville Circle and Frates Road. Those "trips must be either divert to the Calle Ranchero / Fraies Road'intersection, or a new access onto South, Ely Road. For this analysis, all of the exiting left turn movements were diverted to Calle Ranchero.

PHASING PLAN The. Southgate single - family residential homes will be developed in three phases over a 5 -year period. Phase I is anticipated to commence in late spring/earlysummer of 2004 and it is anticipated that development will occur at a rate of 50 homes built per year. It is anticipated that all single- family home construction will be completed by late 2009. Phase IV of the Southgate neighborhood will be developed as a senior affordable housing project of up to 80 units., 'This phase may occur concurrently with one of the three single - family phases or it may occur following the completion of all single- family homes. It should be.noted that the phasing timing and construction rates are estimates based on the demand for residential housing today. Significant changes in the economy and /or housing demand will influence'the rate of home construction. February 6, 2004 SOUTHGA'f.E ANNOTATED CONDITIONS OF APPROVAL Conditions of Approval 1.

US 'NMFS, Santa Rosa, CA, CA RWQCB, Oakland, CA • Enclosure 1 Nationwide Permits 16.. Return Water From Upland Contained Disposal Areas. Return water from an upland, contained dredged material disposal area. The dredging itself may require a Section 404 permit ( 33 CFR 323.2 (d)) , but will require a Section 10 permit if located ..in navigable waters of the US. The return water from a contained disposal area is administratively defined as.a discharge of dredged material by 33 CFR 323 .2 (d) , even though the disposal itself occurs on the upland and does not require a Section 404 permit. This NWP satisfies the technical requirement for °a Section 404 permit for the return water where the quality of the return wafter is controlled by the state through the Section 401 certification procedures. (Section 404) 35. Maintenance Dredging of Existing. Basins. Excavation and removal of accumulated sediment for maintenance; of existing marina basins, access channels to marinas or boat slips, and boat slips too preciously- authorized depths or controlling depths for ingress /egr.ess, whichever is less, provided the dredged °'rriaterial is disposed of, at an upland site and proper siltation controls are used. •(Section 10) • Enc 2 Page 1 of 14. Nationwide ;Permit General Conditions - March 18, 2002 The following General Conditions must be followed in order for any authorization by,an NWP to be valid- 1. Navigation. No activity may cause more than a minimal adverse effect on navigation. 2. Proper Maintenance. Any structure or fill authorized shall be properly maintained, including maintenance to ensure public safety. 3. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be.used and ma- intained in effective operating condition during construction, and all exposed soil and other fills, as well any work below the ordinary high water mark or high tide'line, must be permanently stabilized at the earliest practicable date. Permittees are encouraged to perform work within waters of the United States during periods of ,low -flow or no -flow. 4. Aquatic Life,Movements. No activity m substantial Y Y Y disrupt the necessary life- cycle movements of those species of aquatic life indigenous-to' the waterbody, including those species that normally migrate through the area,.unless the activity's primary, purpose is to impound water. Culverts placed in streams must be installed to maintain low flow conditions. 5. Equipment. - Heavy equipment working in wetlands must be placed on mats, or other measures must be taken to minimize soil disturbance. 6,. Regional and _Case-By-Case Conditions,. The activity must comply with-any regional conditions that may have been added by the Division Engineer (See 33 CFR Part 330.4(e).) and with any case specific conditions added by the Corps or by the State or' tribe i_n its Section 401 Water Quality Certification or Coastal Zone.Managemen Act consistency determination. 7. Wild and Scenic Rivers. No activity may occur in a component of the National Wild and Scenic River System; or in a river officially de'si.gnated by Congress as a "study river" for possible inclusion'i;n the system, while the river is in an official study status; unless the appropriate Federal agency, Enc 2 Page 2 of 14 with direct management responsibility for such river, has • determined in writing that the proposed activity will not adversely affect,. the Wild arid. Scenic 'River de'signation,j or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land maftag,ement agency in the area (e.g., National Park Service, U.S. Forest Service, Bureau of Land Management, U.S. Fish and Wildlife Service). B. Tribal _Rights. No activity or operation may, impair reserved tribal - rights, including, but not limited' to, reserved, water rights and treaty fishing and hunting rights. 9. Water Quality. . (a) 'In certain states and tribal lands an individual Section 401-Water Quality Certification must be obtained or waived. (See 33 CFR Part 3.30.4.(c).). (b) For NWPs 1,2,: 14, 17, 18, 32, 39, 40, 42, 43, and 4.4, where the state or tribal- Section 401 ce- rt ,(eith'pr generically or individually) does not require or approve -water. quality management me'asurea, the permittee must. provide. water q,ual .ty management measures that will ensure that the authorized work does. not result in more than minimal degradation of 'watefr quality (or the Corps determines that compliance. with ;sttate or local stand.a_rds, where applicable, will ensure no more than minimal adverse effect on water quality). An important" Component of water quality management includes stormwat.er managemen.,that minimizes degradation of the downstream aquatic system, including water quality. (Refer- to Gener;al.Condition 21 for stormwater management requirements.) Another _important component of wager quality management is the estab- lishment; and maintenance of vegetated buffers next to open waters, i:nclu_ding streams. (Refer to General Condition 19 for vege.tate'd• buffer requirements for the N:WPs . ) This condition is only applicable to projects that have the potential to affect water quality. While appropriate measures must be taken, in most cases it is not' neces:s.ary to conduct- detailed studies to identify such measures or to require monitoring. 1.0 Coastal Zone Management,,. In certain states, an. individual state coastal zone;mznag'etent consistency concurrence must be obtained or waived. (See 33 CFR Part 330,.4(d)..) , 11. Endangered Species. (a) N.o activity is authorized under any `NWP which is likely t j.eopa- rd'ize the continued exis 'ence of a thr,eaten,ed or endangered ispecie,s or a species proposed for such designat °ion :, 2 Enc 2 Page 3 of 14 as identified under the Federal Endangered Species Act (ESA), or which will destroy or adversely modify the critical habitat of such species. Non- federal-permittees shall notify the District Engineer if.any listed species or designated critical habitat might be affected or is in the vicinity of the project, or is located in the designated critical habitat.and shall not begin work on the activity until notified by the District Engineer that the requirements of the ESA have been satisfied and that the activity is authori..zed. For activities that may affect Federally - listed endangered or threatened species or designated critical habitat, the' notification must :include the name s) of the endangered or threatened species that may be affected by the proposed work or that utilize the, designated critical habitat that may be affected by the proposed work. As a result of formal or informal consultation with the FW.S or NMFS, the District Engineer may ` add species - specific regional endangered species conditions to the NWP_s. (b) Authorization of an activity by a NWP does not authorize the "take" of a threatened or endangered species as defined under the ESA. In the: absence of separate authorization (e.g., an ESA Section 10 Permit, a Biological. Opinion with "incidental take" 'provisions, etc..) from the FWS or the NMFS, both lethal and non - lethal "takes" of protected species are in • violation of the ESA. Information on °the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the FWS and NMFS or their world wide web pages at http: // www .fws.gov /r9endspp. /endspp.html and http: // www. nfms .gov /prot_res /overview /es.html respectively. 12. HistoriqProperties. No activity .which may affect historic properties - listed, or eligible for 1_isting, in the National Register of Historic Places is authorized, until the District Engineer has complied with the'provisd ons of 33 CFR Part 3.25, Appendix C. The prospective permittee must notify the District Engineer if the authorized activity may a- ffec.t any historic properties listed, determined to be eligible, or which the prospective permitttee° has reason to believe may be*elig.ible for listing on the National Register of Historic Places, and shall not begin' the activity until notified by the District Engineer that the requirements of the National Historic Preservation Act—have satisfied and that the activity is authorized. Information on the location and existence of historic resources can :be obtained from the State Historic Preservation Office and the National Register of Historic Places. (See 33­CFR Part 330.4(g).) For activities that may • affect historic properties listed in, or 'eligible for listing in, the National Register of Historic Places, the notification 3 Enc 2 Page 4 of 14 must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 13. Notification. (a) Timing: Where required by the terms of t -he NWP, the prospective permittee must notify the District Engineer with a preconstruction notification (PCN) as early as possible. The District Engineer must determine if the notification-i's complete within: 30 days of the date. of receipt and can request .additional information necessary to make the PCN complete only once. However, if the prospective permittee does not provide all of the requested. information, then the District Engineer will notify the prospective permittee that the notification is still incomplete. a- nd'the PCN review process will not commence until. all of the requested information has'been received by the District Engineer.

(d) District Engineer's Decision In reviewing the PCN . - fo.r.�the proposed activity, the District Engineer will determine whether the;activity authorized by the NWP will result in more than minimal.individua!1 or cumulative adverse environmental effects or may, be contrary to the public interest. The prospective °permittee ma.y submit a proposed mitigation plan with the PCN'to expedite the process. The District Engineer will consider any proposed compensatory mitigation the applicant has included n.the proposal in determining' whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal. If the District En`gi'neer determines that the activity corriplies with the terms and conditions of the • NWP and that.the adverse effects on the aquatic environment are mini -mal, after considering mitigation, the District Engineer 7 Enc 2 Page 8: of 14 will notify the permittee and include any the District Engineer deems necessary. The District. Engineer must • approve.an compensatory mitigation proposal before' th.e permittee commences work If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN, -the proposal may be .either conceptual or detailed. Tf the prospective permittee elects to subunit a compensatory mitigation plan with the PCN, the District Engineer will expeditiously review the,proposed compens.a,tory'mitigati.on plan. The District. Engineer must review the plan within 45 days of `receiving a complete PCN and determine _ whether the conceptual or specific proposed` mitigation would ensure no more than minimal adve =rse effects on the:aquatic environment. If the net adverse e.f.f:ects . of the project on the aquatic environment (after conaider'ation of the compensatory mitigation propos.a,l) are determined by the District Engineer 'to be minimal, the District Engineer will. provide a timely written response. to. the applicant. The response wil,l.state that the pro"ect can proceed under the terms and conditions of the N,WP. If the District Engineer determines that the adverse effects of the: proposed, work are more t -han minimal, then the District Engi -veer will notify the applicant either: (l,) that the project does not qual=ify for authorization under the, N;WP and instruct the applicant on the p roce.dures.to seek authorization under an Individual Permit,,,, (2) that the project is authorized unde "r the N.WP subject to the applicant's submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level; or (3) that the project is authorized under the NWP with speci -fic modifications or- conditions. Whe- re, the, Distri.c;t 'Engineer determines that mitigation is required to ensure no more than minimal adverse effects';, occur to the aquatic environment, the activity will be authori:zed.within the 45 -day PCN period. The authorization will include the necessary conceptual or -specific mitdgat on or a requirement that the: applicant submit a mitigation proposal that would reduce 'he .adverse effects on the aquatic environment to the minimal level When conceptual mi is included, or a mitigation .plan is r.e,qui under item (Z,) above, no ,work in waters of the, U.S. -will occur until the District Engineer h&s approved a spec mitigation plan. (e) Agency Coordination: The District Engineer will consider any comments from Federal and :state a,genci.es concerning . the proposed activity`s c;omp;liance with the terms and cond'i.t.iofts of the NWPs and the need f'or mitigazt'ion to reduce the project' s adverse environmental effects to a minimal level. 8 Enc 2 Page 9 of 14 For activities requiring notification to the District • Engineer that 'result in the loss of greater than 1/2 acre of waters of the U.S., the District Engineer will provide immediately °(e.g., via facsimile t- ransmis;s,ion, overnight mail, or other expeditious manner) a copy to the appropriate Federal or state offices (FWS,, state,-natural resource or water quality agency, EPA, State Historic Preservation Officer (SHPO), and, if appropriate, NMFS). With the exception of NWP 37, these agencies will then have 10.calendar days from the date the material is transmitted to telephone or fax the `District Engineer notice that they intend to provide substantive,. site- specific comments. If so contacted by an agency, the District Engineer will wait an additional 15 calendar days before making'a decision on the notification. The Dis;t.rict,Engineer will fully consider agency comments received within 'the specified time frame, but will provide no response to the resource agency, except as provided below. The District Engineer indicate in the administrative record as,soci-ated with each notification that the resource agencies' concerns were considered. As required by Section 305(b)(4)(B) of the Magnuson - Stevens Fishery Conservation and Management Act, the District Engineer will provide a response to NMFS within 30 days of receipt of any Essential Fish Habitat conservation recommendations. Applicants 'are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. (f) Wetland Delineations: Wetland delineations must be prepared in accordance with the current method required by the Corps. (For. NWP 2'9 see Paragraph (b)(9)(iii) for parcels less than 1/4 acre in size.) The permittee may ask the Corps to delineate the special aquatic site. There may be some delay if the Corps does the delineation. Furthermore, the 45 -day period will not start until the wetland delineation has been completed and submitted to the Corps., where appropriate: 14. Compliance Certificat -ion. Every permittee who has .received NWP verification from the Corps will submit a signed certification regarding the completed work and any required mitigation. The certification will be forwarded by the Corps with the authorization letter and will include;: (a) A statement that the authorized work was done in accordance with the Corps authorization, including any general or specific conditions; (',b) A statement that any required mitigation was .completed in accordance with the permit .conditions; and (c) The s.ignat,ure of the permittee certifying the • completion of the work and mitigation. Enc 2 Page 10 of .14 than 1 5 . Use fo r 0 f Multiple Na.tionwide,.Permit §. The use of more a single and complete project is.prohibit.ed, except when the acreage loss of waters .of the U.S. authorized by the NWP's does not exceed the acreage, limit of the NWP with the highest specified acreage limit (e.g. if a road crossing over tidal waters is constructed under NWP 1:4, with associated bank stabilization authorized by `NWP 13, t'h'e maximum, acr,ea,ge loss of waters of the U.S. for the total project cannot exceed 1/;3 acre). 1 -6; . Water Supply Intakes. No activity, including structures and work in navigable waters of the U.S or discharges of dredged or fill material, may occur in the Proximity of. a public water' supply in't °ake except - where the activity is for repair of the public water supply intake structures or adjacent bank .stabilization. 17:, Shellfish Beds. No activity, including structures :and .work in navigable waters of the U.S. or discharges of dredged or fill,.material, may occur in, areas of concentrated ,sh.ell,fi h populations, unless the activity is directly related to a shellf - .ish harvesting activity authorized by NWP 4. 18. Suitable Material, No activity, including structures and work in navigable waters of the U.S. or discharges of dredged or fill material,,may consist of unsuitable material (e.g.., trash, debris, car bodies, asphalt, etc.) and material used for construction or discharged must be free from toxic pollutants in toxic amounts. (.See Section 307 of the NA:.) 19: Mitigation. The District Engineer will consider. the factors discussed'below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal: (a,) The project must be designed and constructed to avoid and minimize adverse effects to waters of the U'.S. to the maximum extent practicable at the prof e,at 's , ite (i . e . , on 'site) (b') Mitigation in all its forms (avoiding, minimizing, rectifyi`ng,, reducing or compensating) will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c) Compensatory mitigation at a minimum one - for -one ratio will. be required for all wetland impact >s requ a `PCN, unless the District 'Engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project - specific waiver of this Iff J Enc 2 Page 1 I of 14 re'quirement,. Consistent with National policy, the District Engineer will establish 4' preference for restoration of wetlands , -as compensat 'ory' mitigation, with preservation used only in exceptional circumstances. (d) Compensatory mitigation (i.e., replacement or substitution of aquatic resources for those 'impacted) will not be used to increase the: acreage losses allowed by the acreage limits of some of the NWPs. For example, 1./4 acre of wetlands cannot be created to change a 3/4 acre loss of wetlands to a 112 acre loss associated with:NWP 39 verification. However, 1/2 acre of created wetlands can be used to reduce the impacts of a 1/2 acre loss of wetlands to the minimum impact level in order to meet the minimal impact requirement associated with NWPs. (e) To b.e practicable, the mitigation must be available and capable of being done considering costs, existing technology, and logistics in light of the overall, project purposes. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferably_in'the same watershed. (f) Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment, maintenance, and legal protection (e.g., easements,, deed restrictions) of vegetated buffers to open waters. In many cases, vegetated buffers will be the only compensatory mitigation required. Vegetated buffers should consist of native species. - The width of the vegetated buffers required will address documented water quality or aquatic habitat loss concerns. Normally, the vegetated buffer will be 25 to 50 feet wide on each side of t.heA stream, but the District Engineer may require slightly wider vegetated buffers to address documented water quality or habitat loss. concerns. Where both wetlands and open waters exist on the project site, the Corps will determine the appropriate compensatory mitigation (e.g., stream buffers or wetlands compensation) based on what is best for the'aquatic environment on a watershed basis. In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation,, the District Engineer may waive or reduce requirement to provide wetland compensatory mitigation for wetland impacts. (g) Compensatory" mitigation proposals submitted with the "notification" may be either conceptual or detailed. If • conceptual plans are approved under the verification, then the Corps will condition the verification to require detailed plans Enc 2 Page 12 of 14 be submitted and approved by the Corp's prior to construction of the authorized activity in waters of the U.S. 0 (h) Permittees.may propose the use of mitigation banks, in -lieu fee arrangements or separate activity- specific compensatory mitigation. In all cases that require compensatory mitigation, the mitigation provisions will specify the party responsible for accomplishing and /or .complying with the mitigation plan,. 20. Spawning- Areas. Activities, includ <ing structures and work in navigable waters of the U. S.. :or discharges of .dr.edged or fill material, in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the.physical destruction (e.g., excavate, fill, or smother` downstream by substantial turbidity) of an important, spawning area are not authorized. 21. Management of Water Flows.. To the maximum extent p racticable, the activity must be designed to maintain preconstruction downstream flow conditions-(e.g., location, capacity, and. flow rates) . Furthermo.r.e, the activity must not permanently restrict or impede the passage of normal or expected high flows (unless the primary purpose of the fill is t impound waters) and the structure or discharge of dredged or fill material must withstand expected high flows. The activity must., to the maximum extent practicable, provide for retaining exces flows from the site, provide for maintaining surface flow rates from the site similar to preconstruction conditions, and provide for not increasing water flows from the project site, I r locating water,, or redi,re:cting water flow beyond preconstruction conditions. Stream channelizing will be reduced to the minimal amount ne'ce!ss.ary, and the activity must., to the maximum extent practicable, reduce adverse effects such as flooding or erosion downstr'eam.and upstream of the project site, unless the activity is part of a larger system designed to. manage water flows. In most cases, it will not be a requirement to conduct detailed studies and monitoring of water f,low,. This condition is-only applicable to projects that have the potential to affect wate•rflow:s. While appxopri:ate measures must . be taken, it is not necessary to conduct detailed studi,es,to identify4 such me, asures- or require monitoring to ensure their effectiveness. Normally, the Corps will defer to state and local authorities regarding management of water flow. • 12 Enc 2 Page 13 of 14 22. Adverse Effects „From Impoundments. If the activity creat;es,an impoundment of water, adverse effects to the aquatic system due to the acceleration'of the passage of water, and /or the restricting of, its,flow shall be minimized to the maximum extent practicable. This includes structures and work in navigable waters of the U.S., or discharges of, dredged or fill material. 23. Waterfowl_:_Breedinq Areas. Activities, including structures and work in navigable waters of the U.S. or discharges of dredged -or fill material, into breeding areas for migratory waterfowl. must be avoided to the maximum extent practicable. 24. Removal of,Temporary Fills. Any temporary fills must be removed in their entirety and the affected areas returned to their preexisting elevation. 25. Designated Cx t cal .Resource Waters. Critical resource waters 'includ'e, NOAA= designated marine sanctuaries, National Estuarine, "Research Reserves; National Wild and Scenic Rivers, critical habitat for Federally listed threatened and endangered species, coral reefs, state natural heritage sites, and outstanding national resource waters or other waters • officially designated by a state as having articular - g P environmental or ecological significance and identified by the District Engineer after notice and opportunity for public comment -. The District Engineer may also designate additional critical resource waters after notice and opportunity for comment. (a) Except as noted b.elow,. discharges of, dredged or fill material into waters of the U.S. are not authorized by NWPs 7, 12, 14, 16, 17, 21, 29; 31, 35, 39, 40, 42, 43, and 44 for any activity within, or directly affecting, critical resource waters, including wetlands adjacent to such waters. Discharges of dredged or fill materials into waters of the U.S. may be authorized by the above NWPs in National Wild and Scenic Rivers if the activity complies with General Condition 7. Further, such d- i:schar.ges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition 11 and the FWS.or the NMFS has concurred in a determination of compliance with this condition. (b) .For NWPs 3, 8, 10, 13, 1.5, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, and 38, notification is required in accordance with General Condition 13, for any activity proposed in the designated critical resource waters including wetlands 13 Enc 2 Page 14 of 14 adjacent :to those waters. The District Engineer may authorize activities under these NWPs only' after it is determined that the impacts too the critical resource waters will be no more than minimal. 26. Fills Within 100= Year- Floodplains. For purposes of this General Condition, 100 -year floodpla'ins will be identified through the existing Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps or'FEMA- approved local flo'odplain maps. (a) Discharges in Fl- oodpl -ain; Below Headwaters.. Discharges of dredged or fill material into waters o'f,the U.S.. within the ma;ppe 100- year f1oodplain, below headwaters (i.e. five cf -s), resulting in permanent above-grade fills, ar ,'hot authorized by'NW.Ps 39, 40, 4.2, 43, and 44. (b) Discharges in Floodway; Above Headwaters. Dischar-g,es of dredged or fill material into waters of the U.S. within the FEMA or locally mapped fdoodway, resulting in permanent above - grade fills, are not authorized by NW;Ps 3,9, 40, 42, and 44. (c_). The permittee must comply with any applcaFble. FEMA - approved state or local floodp'lain management requirements. • 27., Cgnstruation Peripd.. For activities that have not. been verified by the Corps and the project was commenced 'or under contract to commence by the expiration dada of the NWP (or modification or revocation date), the work must be completed within 12 months after such .date (including any modi-ficat_i6n that affects the project). For aactivities that have been verified and the project was commenced or, under contract to commence within the verifi.cat.d.on . period',, the work must be - completed by the- date determined 'by the Corps. For projects that have been verified by the Corps, an extension of a Corps approved completion date maybe requested..

NOW THERFORE BE IT RESOLVED that the Petaluma City Council hereby approves the Amendment to the General Plan land use designation from "Specific Plan Area" and "Transit Terminal" to "Urban Diversified" based on the'findings speci'fi'ed below: FINDINGS FOR A GENERAL PLAN AMENDMENT: 1. The proposed General Plan Amendment is consistent and compatible with the rest of the General Plan and any implementation programs that may be affected. In September 1999, in conjunction with a previous proposal for .the property, the project sponsor submitted a preliminary application to request that the City Council reconsider the Specific .Plan requirement for the property. At that time, 'the City Council determined that the, site .did not have characteristics typical of a Specific Plan area, and that it was not necessary to prepare a Specific Plan. • ATF'ACB ME= 13 ATTACHMENT 13 The Urban Diversified land use designation would, h'e'lp further the objectives, policies and programs of the General Plan by providing a site that would invite flexibility in site design and, unit type .for residential densities of 5 to10 units per acres. Single- family homes, duplexes, and - multi- family units' are permitted. The proposed amendment is deemed to be in the public interest to, provide for orderly development of residential uses. Furthermore, removal, of the "Transit" designation has been determined 'appropriate in light .of the proposed residential use. 2. The potential impacts of the proposed amendment have been assessed and have been determined not to be detrimental to the public health, safety, or welfare. The Urban Diversified designation, which allows residential densities of 5 to.1.0'.units per acre and invites flexibility in site design,, ;and unit type, allows a range of residential. land uses that are appropriate for the site and that will not create a nuisance to existing surrounding uses. 3. The proposed amendment, `has been processed in_ Taccordance with. the applicable provisions of the California Government Code and the California Environmental Quality Act. The requirements of the California - Environmental Quality Act (CEQA) have been satisfied through the preparation of a Mitigated Negative Declaration, which analyzed the potential environmental impacts of the General Plan Amendment,- and :represents° an adequate documentation of the environmental implications and. 'possible mitigation measures of the proposed project for use in decision= making. SACC -City Council\ resolutions \Southgate3_GPA_030104.doc 0 2 ATTACHMENT 14 • ORDINANCE NO. N.S.C.

The City Council finds that the Planning Commission filed with the City Council its report set forth in its minutes, of January 27, '2004, recommending the adoption of an amendment to Zoning Ordinance ' Section 1072 N.C.S., as amended, by reclassifying and rezoning certain lands being more particularly described as Assessor's Parcel Nos 017- 030 -022. AND '017- 1'50- ,01`9, a 40 -acre site located at the corner of Frates Road and Lakeville Highway. Section 2. The City Council further finds that said Planning Commission held public hearings on said proposed amendment on January 27, 2004, after giving notice of said hearing, in the manner for the period, and in the form required by said Ordinance No. 1072 N.C.S., as amended. Section 3. Pursuant to the provisions of Zoning Ordinance No. 1072 N.C.S., as amended, the City Council finds as follows: The. proposed Amendment to Zoning Ordinance No 1072 N.C.S., to classify and rezone the subject parcel from Study District to Planned Unit Development (PUD), will result in a more desirable use of land and a better physical environment than would be possible under any single zoning district or combination of zoning districts.. The proposed uses comply with the Urban Diversified land use designation of the General 'Plan, 'which allows for residential densities of 5 -10 units per acre and invites flexibility in site design and unit type. In addition, this proposal incorporates the policies and guidelines of the Planned Unit. Development of Article 19A of the Zoning Ordinance. • ATTACHr%AENT 14 2. The public necessity; convenience and welfare clearly permit and will be furthered by the proposed: Amendment to the Zoning Ordinance, reclassifying and rezoning the project site to Planned Unit Development. The. PUD - Development Standards (as revised) for the Southgate ;Residential Development identifies permitted and conditional uses allowed 'within the approved PUD. The requirements of the California Environmental Quality Act (CEQA) have been satisfied through the preparation of an. Initial Study and Draft Mitigated Negative Declaration to .avoid or reduce to a .level of insignificance, potential impacts generated by the.proposed Southgate - Residential Development. In compliance ew. with the:requirements of the California Environmental Quality Act, an InitialStudy was prepared for "the So;uthgai:e Residential Development: Based upon the ' Initial Study, a determination was made that no significant environmental effects would result.

'Hazards ,,& Hazardous Materials Environmental Setting The 90 -acre project site, which consists of two adjoining parcels, is :locate,d on the south side of Frates Road between Lakeville Highway (SRI 16)° and E- ly Road. The Old Lakeville Road right -of -way (proposed to be abandoned) separates the two .parcels. The site, which has a gentle riorth to south cross slope, is unimproved. and is sparsely vegetated with remnant grasses. There are no trees .on the subject property. In the past, the. property was used as pastureland and for hay production. More recently, a portion of the site was used to stockpile fill material from.nearby construction sites for which a use ,permit was granted. A 120 -foot' wide PG &E transmission line right -of -way easetnenCruns along the eastern edge of the project site. A City pump station exists at the northeast' corner of the site, near th "e' intersection of Frates Road and Ely Road. The property was annexedinto the City in:1985 along with Adobe Creek Golf and County Club, and:is,only property on the south side of Frates Road within the City's Urban Growth Boundary. The property is currently zoned S -Study Area, and the: General Plan. land use designationfis "Specific P1an,Area ". In addition, the City of Petaluma General Planjand,use;map designates the comer of the property near'the Frates /Lakeville Highway intersection as a Transit Terminal (Park and, Ride) location and a band of the Urban Separator followed by the Urban Growth Boundary is shown along the southern and eastern'boundaries of the site.

"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- outsider 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 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, an&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 'Thai, Significant With 'Mitigation Incorporated applies where the incorporation of mitigation measures has reduced an effect,;from "Potentially Significanfirnpact 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- referericed). 5) Earlier analyses may be used where, pursuant°to the tiering, programEIR,, or other CEQA process, an effect has been adequately analyzed - in an earlier EIR or.negative declaration pursuant to,Section 150630)(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 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 nitigatiorrmeasures based on.the earlier analysis. C) Mitigation Measures. For 'effects that are 'Less than Significant with Mitigation Measures Incorporated," describe the mitigationmeasures that were 'incorporated or refined from the earlier document and :the extent to which they address site= specificconditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to.`information sources for potential impacts (e.g., general plans, zoning7 ordinances). Reference to a previously prepared ,or outside document should, where appropriate, include a reference'to thepage orpages 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. • Page 6 Project Name: Southgate File.

X X Discussion: The subiei(vproperty is currently zoned S -Study District and the General Plan land use designation: is "Specific Plan Area ", In the City U'Petiluina, General Plan land use designates the corner of the property near'the. Frates /Lakeville Highway intersection as ,a Transit•'Termnal (Park and Ride), and, a'band of the Urban Separator followed by the Urban Growth Boundary is,sho;wnalong. the +south and east boundaries of . site: The project sponsor has submitted applications requesting. approval of a general. plan. amendment and a rezoning; of property. The ,general plan amendment would t change the land use designation from the- .current "Specific, Plan Area"' "Transit" designations' to the "Urban Diversified "'land use. designation, which would allow` residential densities of 54U ,units per acre,- or 200400,, housing units on the .project site. The proposed rezoning would replace the existing "Study` Area" with a' Planned; Community (P -C) District. There_ is no existing habitat conservation plan or natural community conservationplan -that exists .for this area of. the City. The property was annexed into 'the City in 1985 along, with the: Adobe Creek Golf and Country Club located. northeast, of the project. site. At the time of the annexation, the site's. zoniri g ff ,'designation Study District, was purposefully.retained. for future. interpretation. According to sta reports °pertaming annexation, the site was being cons idered',for,theoddevelopment of °a 200 unit residential development. The site was later,considered by the Santa,Rosa Junior College for its Petaluma campus and by local school districts for art elementary or junior high schoolsite. The site was deemed not suitable for their. needs. - During, ,the 1987- 2005 General, Plan rewrite,. the City _Council; ,considered, designating the site Special Industrial„ ;since they found. the: cite to be well suited for a .campus -like development that would have an appropriate `land use intensity and the potential to provide an, attractive, gateway -to the City; as well as ', a , ,. transition from the agricultural lands to the east' within the County. However, due to concerns regarding; a proposed residential development the site was designated as a Specific Plan Area in the 1987- 2005 General Plan and accompanying land, use map. In September 1999, the project sponsor (formerly 'known as G &W 'Management), submitted a preliminary ^applicationao request.. that the City Council reconsider the Specific Plan, requirement, for the property: At that time, the: project sponsor envisioned the property being developed assa business park, and proposed;a Spec ial:Indus'tria1/0ffice Park land .useAesignation for the�site. The Council determined that the site did not have characteristics typical I of , a _Specific Plan area, and that it, not necessary to prepare .a Specific Plan,,particularly in light of the proposed single ownership. The council indicated thatit was appropriate for the project sponsor to move .forward with an application for a General Plan Amendment :for the property and expressed a desire to see an analysis of the jobs/housing balance and an economic analysis of the optimum use of the parcel. General Plan Amendment The change,to an'Urban Diversified General Plan land use designation would allow densities, of 5 -10 units per acre,. or 200400 housing units on the project'site. This designation 'is intended to "invite flexibility in site design and' unitAype. Single family homes, duplexes, and multi family units are permitted. The!proposed project, which would of 221 single family homes and affordable housing units would meet the `intent ofthis land use designation. Page 7 Southgate Initial Study re o Potential, Less Than Less Than No Significant, Significant Significant Impact Impact Wl/Mitigation Impact Incorporated Transit Designation. The City of Petaluma .General Plan land use, map designates the ..corner of the property near the Frates /Lakeville Highway intersection as a Transit Terminal (Park and Ride) location. This: designation which. includes the concept that a park and ride facility should be located on this site, would not be , compatible with the development plan. The City's transit. coordinator recommends that a bus stop and shelter be :installed on ; Frates Road to serve future residents of Southgate as well as the residents of the adjacent neighborhoods. As a result, removal,'of'the transit designation from the property would not conflict with the overall"intent of the General Plan policies regarding transit opportunities. Urban Separator. A band of the Urban Separator' followed by the Urban Growth Boundary the south and east property line of the project site. The General Plan describes the Urban Separator as, a visible band of open space that marks the edge of allowable development. It is continuous on the east. side,. intermittent on the west side and runs adjacent to the Urban Limit Line for most of its length. The Urban Separator provides an edge that buffers farmland`from urban land. It can serve as a recreation area and a key component of the City "s'.'open space system. It prevents urban developrnept from extending unchecked into surrounding open space, since private development cannot take place within thesseparator; The Southgate plan shows a 120 -foot wide, 1`,500+ foot long area along the south "side, of the site. The plan also shows a 20 foot wide landscaped area adjacent to South Ely Boulevard, between the current. edge of pavement and the rear lot fencing. Both of these areas border the City lin-tits, and the Urban Growth Boundary. Although the, Land Use Map of the General Plan depicts the Urban Separator as a uniform width along the north and east property lines, General Plan objectives related to the Urban Separator indicate that the Urban Separator shall be a maximum of 300 feet except in those areas where it may be variable or is already established at more than 300 feet, neither of which:are the case for the subject property. The policy makers for the City of Petaluma, in conjunction with their.review of the Southgate development, will determine whether the project, as proposed, meets the intent of the various objectives policies of the General Plan, including those related to the Urban Separator. Rezoning The proposed rezoning would replace the existing "Study District" with a Planned Unit Development (PUD) District.

Discu §lion: The topography of the site, can .be characterized as nearly level. ,In the ,past; the property was used as pastureland and for hay production. More recently, a portion of the site was used to stockpile fill material from nearby construction sites, for which a use permit was granted. According to a Phase I Environmental Site Assessment prepared for the project site, the fill material was loosely placed on the subjects ite and spread. No compaction or engineering controls were performed during fill placement (Kleinfelder, March '1999)'. There. are no unique geologic or physical features on the site. Based on the borings that were taken as part of a preliminary geotechnical investigation, the report states that near- surface soil conditions beneath the site (0-4 feet) consist of black clay '(adobe) which exhibited shrinkage cracks to. a depth of four feet (Harding Lawson, 1982). Alternating layers of clay and sandy clayey gravel were encountered'below clay level to the maximum depth of the boring ,(20.feet), Groundwater was encountered at a minimum depth of . approximately 6.5 , feet: below the existing grade. ''The report states that no free groundwater was encountered in the borings. The . soil encountered is typical, of an alluvial soil deposit. Adobe soil often requires reconditioning prior to site development. This may require the import'of additional soil. The seismic activity of Sonoma County, as as the entire North Coast region, is the: result of readjustments to opposing forces along various northwest trending strands of the San Andreas Fault between the: North American and pacific crustal plate boundary. No active faults are known to, exist on the,. site, and the site is not within an Alquist - Priolo Earthquake Fault Zone. Known active faults near the site include the San Andreas Fault and the Rodgers Creek. 'Fault. The San Andreas Fault is located approximately 14 miles southwest of the subject property.. The Rodgers Creek Fault is located approximately 4 miles g g ' g red to have a high northeast of the site. However, seismic round shakin is a eolo is hazard considered potential to affect the g p site during the life of the project. Ground shaking is '4 hazard potentially affecting all structures in the North Coast region and is typically mitigated through appropriate structural design and construction of buildings. Due to the presence of sandy soil the site may be subject to liquefaction and liquefaction induced settlement during a significant, seismic event. Mitigation measures recommended below would reduce these potential adverse impacts to a -level of less than significant. Mitigation Measures/Monitoring 3.1 All earthwork, grading, trenching, backfilling, and compaction operations shall be conducted in accordance with the City of Petaluma's Subdivision Ordinance ( #1046, Title 20, Chapter 20304 of the Petaluma Municipal Code) and Grading and Erosion Control Ordinance #1576, Title 17, Chapter 17.31 of the Petaluma Municipal Code). 3:2 The project sponsor shall submit an Erosion and Sediment.

Where available, the significance of criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following detemiinati Would the project: a. Conflict with or obstruct implementation of the applicable air quality plan? b. Violate any air quality - standard or contribute substantially to an existing or projected air quali violation? C. Result in a cumulatively considerable net increa criteria pollutant for which the projectregion is attainment under an applicable federal or state a air quality standard (including releasing emissio exceed quantitative thresholds -for ozone precun d. Expose sensitive receptors to substantial polluta concentrations? e. Create objectionable odors affecting a substanti, of people? Discussion: The Bay Area Air Quality Management District, (BAAQMD) is the regional agency .responsible for overseeing compliance with State and Federal_ laws, regulations', and programs within 'the San Francisco Bay Area Air Basin.. The BAAQMD has prepared and/or implements specificylans to meet the applicable, laws, regulations, and programs. Among them are the Carbon Monoxide Maintenance Plan (4994), Bay Area Clean Air Plan (1997), and the Ozone Attainment Plan (1999.). The San Francisco Bay Area is considered to be one of the cleanest major metropolitan areas in the country with respect to air quality. For the most part, air quality in Petaluma is considered to be very - ;good. Based on measurements taken at the BAAQMD monitoring station in Santa Rosa (the station closest to 'Petaluma) the pollutants of most concern to the Petaluma area are ozone and smallparticulaie matter (PM Automobiles are primary source of air pollutants in Petaluma. The combustion of fuel for space and water, heating is, another source of air pollutant emissions. Wood burning and other outdoor burning is a source of air pollutants during late fall and winter. Short -Term Construction Impacts Construction- related activities such,as grading„ paving and building construction,would,generate dust, or small particulate matter (PM that could lead to both.health,and "nuisance impacts ifnot controlled. Mitigation Measures identified below would reduce temporary construction- related air quality impacts to less than significant. Long- Term.Air Quality Impacts After construction" of the proposed project is completed, the main project - related impact to air, quality, would result from increased automobile traffic. To, assess. long-term air quality impacts, air pollutant, emissions were calculated using the URBEMIS 2002 model. The model predicts °eemissions from both mobile sources (i.e., project generated traffic) and area sources (i.e., residential space and water' heating, 'landscaping and consumer products). Emissions were predicted for the year 2007, when the project is expected to be completely developed and operational. The volume of automobile�traffic generated by the project was based on the traffic assessmentpreparedby Dowling Associates. The Bay Area AinQualiy Management District (BAAQMD) has identified significance thresholds_ for project emissions of ozone precursors " (reactive orgariic gases and nitrogen oxides) and PM 10 as 80' pounds per day each of the pollutants. The Urbemis2002 modO'included defaults for San Francisco Bay Area region. Emissions for each of the pollutants would be less than the significance threshold of 80 pounds per day. Model results are summarized in the table below: Page 12 Southgate lnitial'Study Page 13 Potential Less Than Less Than No Significant Significant Significant Impact Impact w /Mitigation Impact Inco orated. Table 1 SOUTHGATE — URBEMIS2002 Emissions for 2007 in pounds per day BAAQMD Threshold ROG (801b /day) NOx (80 lb/da pmfo (80_Ib /day); 41 29 24 _ Source: Illin worth &;Rodkin - Southgate Air Quality Emissions Report, 1'0/24/03 Given the low background carbon monoxide concentrations and, relatively low traffic volumes, 'traffic conditions associated with the project-are not expected to cause or contribute to any violations of ambient carbon monoxidetstandards. Construction of the - project would lead to. temporafy.emissions of dust and; equipment exhaust, especially during grading. The BAAQMD considers projects that; °implement appropriate PM 1.0 control measures to have .a less tlian significant impact on air quality :during construction. Without appropriate control measures, construction activities, could result in a significant impact to air: quality. Mitigation Measures identified below would reduce construction- related air quality impacts to less than significant. Mitigation- , Measures/Monitorine : 4.1 The Project sponsor shall incorporate Best Management Practices into grading, building and/or improvement: plans, and clearly indicate these provisions in the plan spec'ifications. The construction contractor shall incorporate th_.e following 10 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_ mu and maintained to rmnim ze 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 15 ;mph. Only purchased city "water or reclaimed water 'shall be used forAhis purpose Responsibility for watering 'to include weekends and holidays when wof js not progress. c. Construction sites involving earthwork shall. provide :for a gravel pad area consisting ofan impermeable 'liner and drain rock at the construction entrance to clean mud: and debris 'from construction vehicles,pnor to entering thepublic roadways. 'Street`surfaces in the vicinity of'the project shall be routinely swept and cleaned 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, of" maintain,.at, least 'two feet of freeboard to reduce dust emissions. 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 Certificate of Occupancy. 1. If necessary, install windbreaks, or use trees /'vegetative windbreaks at the windward side(s) of construction areas to prevent visible dust clouds from affecting nearby sensitive uses (e.g., residences). m. Suspend excavation and grading activity when winds (instantaneous gusts) exceed 25 mph and visible dust emission cannot be prevented from leavin&the construction.site(s). n. Limit areas subject to disturbance during excavation, grading, and other construction activity at any one time. o. Project sponsor 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 permits. d. If applicable, the project sponsor shall obtain operating permits from the Bay Area Air Quality Management District, and shall provide evidence. of compliance prior to requesting a Certificate. of Occupancy. The Planning Department and/or Building Division shall verify that the project' sponsor has obtained.an operating permit and that the facilities conform'to the permit requirements prior to authorizing the Certificate of Occupancy. 5. HYd'rolociy 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:'eiosion orsiltation on- or off -site? d.

X X X 194 Discussions The site,, which has historically, been used. for agricultural production, has a slight slope ,(less than 1%o) .A shallow drainage. ditch runs along the northeast side of the property adjacent to Ely Road. Groundwater is estimated to,occur'at.depths of 5 to 10 feet and,,drain;to the south/southwest. The site is.not'within the flood plain of.°the Petaluma River (FEMA Flood Insurance Rate Map (FIRM) Community Panel No. 0603790003 C Revised. September 29, 1989). Development of the site would result in increased, runoff as a result, of new impervious surfaces due to buildings,, parking areas, street improvements ,,(i.e: stub /gutters /sidewalks)., Site clearing grading and compaction. of soil :necessary for project construction has, the potential to result in discharge of sediment and temporary water quality,impacts The project would be required to employ best management practices (BMPs) in accordance with the City of Petaluma standard, conditions irrorder to minimize water,quality impacts. A key feature of the proposed Southgate site design is an extensive storm water management/biofiltration system that allows runoff to be captured and absorbed on the site. `The 120400t wide linear park that runs alongithe'east edge of'the project site is intended to function as: a• collector of storm water "from the 'entire site It; in turn slowly feeds into .a retention basin, which is also intended to serves as a wildlife, habitat. and recreational amenity This storm water, system is expected to minimize the amount' of runoff generated by site development.

However, _giver, the distance of the project site from the Bay and the Pacific Ocean, seiche effects, +and tsunami waves do 'not a significant threat to the site. Likewise, mudnows would be insignificant due to the location of'the site relative to hill slopes. The following mitigation, measures would reduce water related impacts'to less than significant. Mitigation Measures/Monitor.'ine 5.,.1 All construction activities shall be performed in a manner that: minimizes . the sediment, and/or pollutants entering, directly or indirectly' into the storm.drain system' or ground water.

Potential Less Tfian Less Than No Significant Significant' Significant Impact Impact: w /, Mitigation Impact Incorporated . X X X Discussion: The: major' noise, source affecting the project site is vehicular tra-ffic on Lakeville. Highway, and to a -much lesser extent; Frates and:'.Ely Roads., The site is. not.significaritly impacted by aircraft noise, and is not within the noise contours for the Petaluma 'Municipal Airport located approximately 1.5 ;miles northwest of the site (Coml)rehensiVel Airport Land Use Plan for Sonoma County, January 2001:). Surrounding land uses include, residential uses to the north and northwesY(across Frates Road), light 'industrial - uses to the west/southwest (across Lakeville Highway), :and agricultural uses ,to .;the east and northeast. The Community Health. and Safety Chapter of P.etaluma,General Plan, which:includes the State mandated Noise Element; identifies residences, schools, churches and hospitals as examples of sensitive noise receptors. The General' Plan stipulates that interior noise levels for residential uses shall be mitigated to,Ld 45, .and L d ; 60 is'established,as the reasonable noise level for exterior use areas. Noise environments with levels up to 70 L are considered conditionally acceptable', ,provided that a detailed analysis of 'the noise reduction requirements is made and needed noise insulation features are included in the project design. The General Plan notes 'that :conventional construction, assuri ing closed windows and 'fresh air, supply systems or. air 1. conditioning, will normally meet- these requirements. The nearest residential property is located across .Frates Road, approximately 1.00 feet from the project site. A masonry wall is located along the north side of Frates, between the sidewalk and.the residential properties. According to the 'CEQA Guidelines Appendix; G, a project will normally have a significant effect on the environment if it would result in "exposure of persons to or gerieratioli of noise. levels in excess of : standards established in , the local. general plan of noise ordinance; or applicable: standards of-other agencies: For purposes of assessing noise impacts associated with the proposed project; an interior noise level of Ld„ 45, and L d „ . 60' for• exterior use areas was used as the significance threshold, based on,the CEQA criteria•cited above. A Noise Mitigation Study prepared by Rosen Goldberg & Der Acoustical Consultants presents the results of on -site noise monitoring and the zpTojected future noise levels calculated for the backyards of homes proposed along the two major roadways: Frates:Road and Lakeville•H ghway (S R1,16). The future noise levels were calculated,both with.and without a noise barrier (soundwall) proposed as,part.of'the project. Note: The addendum: to the Noise Mitigation Study:assumed the height' of the proposed wall to range from 6 to 10. feet in height. Noise measurements were conducted to quantify the existing noise environment, including one .continuous 36-hour noise measurement and. three short-term 15- minute _measurements. To determine the sound level in"the proposed backyards, adjustments were made to account for distance and future traffic. The in noise sources That affect the ; project site are vehicular: traffic on Lakeville ,High. way and Frates' 'R'oad. Lakeville Highway has a significant amount of truck traffic. Frates Road also has truck traffic, but to a lesser extent: According to the; project traffic study traffic volumes are ,expected to . increase by.7% and 19 % along Lakeville Highway and Frates Road, respectively. This traffic volume,' increase corresponds to ” a future roadway noise increase of less than 1 dB for both roadways. Page 18 Southgate Initial Study Page 19 Potential Less Than Less Than No Significant Signi:ficam Significant Impact Impact wNitigation Impact Incorporated Interior Noise Levels The noise mitigation report concludes that an interior noise level of Ldn ,of 45 dBA: can be met through the use of high quality sound rated windows. In addition, modified exterior wall constructions may be .needed at second floor ;rooms along the roadways. These modifications may include extra layers of gypsum board or additional'stud:framing. Outdoor Noise Levels An: addendum to the original noise. studywas submitted on February 6, 2004, to address the revised plans submitted for the project. This addendum concludes thai , noise levels in all backyards would be reduced to a DaylNight= Average Sound Level (DNL) of 60 dBA provided that a 6 to IOfoot noise barrier (sound wall) is provided along Lakeville Highway. Mitigation Measures below, which require that all - proposed residential uses meet interior and exterior significance thresholds, would be necessary to reduce noise impacts to less than significant. "Itshould be notedithatthe original Noise Mitigation Study characterizes the interior Ldn' 45 and exterior Ldn 60 noise levels referenced in the City's General Plan as "goals" rather than standards. In addition, the study also references Caltrans' noise abatement criterion. ,If the City of Petaluma' general plan did not specify any noise standards, it night be appropriate to consider the Calirans noise abatement criteria. However, that is not the case. The study further points out that although the Ldn for these 45 homes is up to •4 dB above the City's outdoor "goal ", a MB increase in noise levels is considered a just noticeable difference, while a 5 dB change is clearly noticeable but not dramatic. Nevertheless, absent any clear policy bythe City of Petaluma that points to a different interpretation of the general plan noise standards, the interior Ldn 45 and exterior..Ldn 60 noise levels referenced' in the City's General Plan are considered to be the'most appropriate thresholds for assessing' noise impacts, in accordance with.CEQA criteria. Temporary Construction Noise • Construction activities associated with the proposed project would temporarily increase noise levels on the site and adjacent properties. Noise levels during construction would fluctuate depending on the ',particular construction phase (grading, foundation, framing, painting, etc). The, mitigation measures identified below would reduce temporary construction - related noise impacts to less than significant.

Potential Less Than Less Than No Significant Significant Significant Impact Impact w /Mitigation Impact inco a Discussion: The site is currently vacant, and undeveloped. Based on, the conclusions of a Phase I Environmental Site Assessment prepared for the project site, there 'is no indication that are ,any hazardous substances, above or below the ground, that would result in the release of hazardous substances during grading or construction. . Given the past agricultural use of the site, it is possible that agricultural chemicals, including ;pesticides, were applied in : conjunction with past farming practices. However, this typically does not.pose a concern except where pesticide- storage or mixing occurred resulting in concentrated residues. The report concluded that there. were no unusual surface conditions observed to, suggest the presence of pesticide residues and there were no previous structures identified on the site which might have been used for pesticide storage of mixing. As stated previously a portion of "site has been used to stockpile fill material from nearby construction sites, for which a use permit was granted. Duritig the Phase I Assessment, information was obtained that'identifies the source of the fill material as originating from local residential or commercial developments or from native soils: underlying roadways where the potential for contamination is low. Except, for miscellaneous inert materials (concrete, plastic irrigation pipe), there were no i other observations made to indicate that fill soils contained potentially hazardous materials. The Phase I Assessment identified two properties near the project site that are known to contain or have contained hazardous in Sola Optical USA, located southeast and downgradient from the site, across Lakeville Highway at 3600 Lakeville Highway, Js listed as a federal'Superfund site supervised by the U.S. Environmental Protection Agency (EPA). The Sola site has been subject to extensive remedial: work and continues to be monitored. Groundwater samples taken at upgradient monitoring wells located between'the _Sola site and the project site did not show signs of contamination. Groundwater has consistently been shown to'be in a southwesterly flow direction beneath the Sola site, in the opposite direction from the project site. The other property identified in the Phase' I study is located at 1,520 Rio Nido Court which is located northwest, and cross gradient from the project site in a residential area.. In February 1997, an apparent .sewer line break allowed the discharge of approximately 1375 gallons of raw sewage to - enter a storm drain that discharged to surface waters of Adobe Creek. The release appears to have been a one -time incident, and does notpose a threat to the project site (Kleinfelder, Inc., 1999). The proposed project is,. not expected 'to. involve the use or storage of hazardous substances beyond those standard cleaning supplies found +most residences;,throughout Petaluma., Therefore, the proposed project would not result in any hazard' to the public or the "environmeni. related .to the release of hazardous substances. The proposal will. not interfere with emergency evacuation plans, create potential health hazards, or result in an increase due to flammable, brush, grass or trees The proposal is located approximately 1.5 miles from the Petaluma Airport, is not within the boundaries of.,airportland useplan and wouldnot create a safety hazardfor people residing in or working in the project area. The property does not exist withiwan area where, wildfires are, likely to occur. Therefore, no_ significant impacts related to hazards or hazardous materials are expected to occur as a result of this proposal. Mitigation Measures/MonitoriLig None, required. 10.

The proposed project is expected to generate 2,493 daily vehicle trips, which includes 179 new a.m. peak hour. trips and 242 new p.m. peak hour 'trips. Regarding the 4.6 -acre open space park and the 1.34 acre neighborhood park, normal usage of these facilities would be by local residents and employees. These facilities are not intended to meet • other recreational facility demands for the other residents within the City. Therefore, it is assumed that the use of these recreational facilities would not generate a significant amount of trips. Existing Intersection Conditions (no project). All of the study intersections currently operate, acceptably at Level of Service (LOS) C or better except for one location: • Frates Road at Adobe Road operates at LOS F during the AM and PM peak hours. Based upon the peak hour signal warrant criteria, a traffic signal is warranted for Frates Road at Adobe Road. Existing Plus Project Conditions. When the traffic generated by the project is added to the existing condition, all of the analysis intersections operate at LOS D except for two locations, which operate at unacceptable levels of service (LOS E or F). • Frates Road at South Ely Road is reduced to LOS E in the PM peak hour Frates Road at Adobe Road is reduced to LOS F . Based upon the peak hour signal warrant criteria, a traffic signal is only warranted for Frates Road at Adobe Road. Mitigation measures are recommended that would result in acceptable levels of service at all intersections under existing plus project conditions.

Transportation impacts attributed °to the project wouldbe reduced to a less than significant level with incorporation of the following mitigation measures. 10-1 A four way slop control or: traffic signal shall "be installe&at the Frates Road intersectioiewith Calle Ranchero. 10 -2; A four way stop. contr'ol or a traffc signal shall be installed'atFrates Road, intersection with South -Ely Road., 1:0 -3 Stop controls shall be,provided for exiting the project at the proposed access point at Lakeville Circle. 10 -4 The ;project shall comply with the requirements of the_ City of Petaluma Bicycle Plan. Plans, for each phase of site development shall be; referred to the 'Pedestrian and Bicycle Advisory_ 'Committee (PBAC) for review and comment to ensure: compliance with the City. Bicycle Plan: Page 29 Southgate Initial Study Page 30 i Potential Less Than Less Than No Significant_ Significant Significant Impact Impact w /Mitigation Impact incorporated 10 -5 The project sponsor shall provide�a Traffic Control Plan for review and, approval of the City's Traffic Engineer, prior to issuance of a building or grading permit. At least, one lane of traffic in each direction shall be maintained at all. times through the construction period, unless a temporary detour plan `is submitted. and approved the City Traffic Engineer. Heavy construction traffic and 'haul trucks shalt avoid school zones between school arrival and departures times. During non - working hours, open trenches and construction ,hazards shall be provided with signage, flashers, and barricades approved by the Street Superintendent to warn oncoming, motorists, bicyclists, and pedestrians of potential safety hazards. 10 -6 All road surfaces shall be restored to pre project: conditions after completion of any project- related utility installation activities. All trench pavement, restoration within existing asphalt streets, shall receive a slurry seal. If the trench cut is within the parking strip, then only the parking strip needs a slurry seal. Otherwise, half the street shall receive a slurry seal. 10 -7 Any pedestrian access through and/or adjacent to the project site shall remain unobstructed during project construction or an alternate route established as' approved :by the Police Chiefand City Engineer. 10 -8 Frontage improvements shall be installed in accordance with the City's Street Standards to provide for safe access to and from the site. Turning lanes, acceleration and - deceleration lanes, curb cuts, median islands, signing and striping shall be incorporated into the +design "plans as required by the City's Traffic .Engineer. Pedestrian and bicycle access connecting the City's bikeways , and pedestrian circulation through the site, shall be, incorporated into the development plan. Improvement or construction plans shall be subject to review and approval of the Traffic Engineer prior to issuance of a grading or building permit. All street frontage improvements, shall, be constructed to City standards and inspected by City Inspectors prior to:final inspections or acceptance of improvements. 10 -9 The project sponsor shall be responsible for the payment of the City's Traffic Mitigation Fees. Traffic Mitigation Fees shall be calculated at the time" of.issuance of a, building permit and shall be due and payable before final inspection or issuance of a certificate of occupancy. 10 =10 The project sponsor shall install a transit stop on Frates Road including a .bench, shelter and pedestrian access, as required by the City of Petaluma. 10 -11 The project sponsor shall be responsible for a fair -share contribution to fund, to the construction of signal and/or other improvements at the Frates /Adobe Road intersection. The fair -share contribution shall be based upon the project's contribution to the cumulative'traffic projected -for this intersection. 11. Public' Services a.

Potential Less Than I Less'Ttian No 'Significant Significant Significant Impact Impact w /Mitigation Impact Incorporated I I I X I Discussion: Additional fire and police service calls, as well as road maintenance, may occur as a result of`this proposal. However, the impact` schools; parks,.or other goverrithe.ntal services'would be minimal. The project; sponsor will,l e subject to the applicable;development .fees that are required-of all developments in order to offset'the`impacts that the would have on public services' `These .include; school fees, traffic mitigation fees and .cor imunity facilities fees, as required' Title 17, Chapter 1.7:14 of the Mudicipal' Code. Fees;are calculated by the City at the time of building permit .issuance and are due and payable by the project- sponsor prior to final inspection or issuance of a Certificate of Occupancy. Therefore, no significant environmental impacts will occur as result of this project. Mitigation Measures/Moiiitoring Not applicable. 12. Recreation a. WouldAe,project increase the use of existing neighborhood and regional parks -or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b. Does the include recreational facilities orrequire the construction or expansion on recreational facilities which mighthave an adverse;physical effect on the environment ?' 1►1 Discussion: The' Southgate Plan proposes a L 09 -acre- neighborhood park to Abe. located ,along the Urban: Separator/PG &E easement, which is to.provide:a 4.46- acre,passive'!reereational area along- the southern edge. of the site. Proposed recreational facilities .would - provide on -site :recreational opportunities,, and combined with the payntent of �comtnunity :facilities fees„ would reduce impacts on existing and regional parks to significant: Furthermore, proposed recreation,facilities are not expected to have an adverse physical effect -on the environment. 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 con. struction 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 stonwwater drainage facilities or expansion of existing, facilities, the construction of which could cause,significarit environmental effects? d.

Be served by landfill with sufficient.permitted capacity to accommodate the project's solid waste disposal needs? Comply with federal, state,,and.local statutes and regulations related to solid waste ?' X F4 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 General Plan. The proposed on -site storm water management/bio - filtration system (landscaped detention areas); would allow runoff to be captured and absorbed on the site. This storm water system is expected to minimize the amount of runoff generated by site development to the extent that the system achieves a "zero -net- increase" in runoff rates during peak,rain events. The system will hold water, on, site so as not to impact properties downstream. For the above reasons, it is expected that no significant impacts to the utility infrastructure would occur as a result of the proposal. Mitigation Measures/Monitoring Not applicable. 14. Mineral Resources Would the project: 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? Fi M Discussion: There is no information about this site from the General Plan or additional studies, which indicates that the site has been known to be a mineral resource. The proposed project would not create a significant impact to known mineral resources. Mitigation Measures/Monitoring Not applicable. 15. Cultural Resources Would the project: . Cause a substantial adverse change in the significance of a historical. resource as defined in §15064.5? b. Cause a adverse change in the significance of an archaeological resource pursuant to § 15064.5? C. Directly or indirectly destroy a unique paleontological resource or site or unique, geologic feature? d. Disturb any,human remains, including those interred outside of formal cemeteries? X X X X Discussion: The project site has been assessed as part of several historic and archaeological investigations, including an • evaluation of the entire Frates Ranch.study area which covered over 580 acres including the project site (Origer and Roscoe 1981); pipeline alignments for the City Petaluma Zone IV Water Delivery System (Flynn 1990) and Lakeville Highway improvements (Roop 1992). Although several prehistoric and historic sites were identified on the larger Frates Ranch property, none of these sites are located on the subject property. A Cultural Resources Evaluation of the property prepared by Katherine Flynn, Archaeological Resource Service, 1997, concluded that given the negative findings of the earlier archaeological studies pertaining Page 32 Southgate Initial Study Page 33 Potential Less Than Less Than No Significant Significant Significant Impact Impact w /Mitigation Impact Incorporated to the property and.adjacent properties, the archaeological sensitivity of the site is considered low. However, there is still the potential that buried artifacts could be present but not presently visible This is due primarily to the site's proximity to Adobe Creek. It'is likely that-the original. meandering course of Adobe Creek would have been used as trail by Native Americans. In addition, the Area where Adobe Creek joined the Petaluma River was known to have contained wooden wharves and docks used by General Vallejo during his occupation of Rancho. Petaluma, centered at the Petaluma Adobe (located approximately 1.5 miles northeast of the project, site), and was used in the early 19` century as a landing area for boats used to transport the bides and tallow from General Vallejo's rancho to other places,in the San Pablo and San Francisco Bay areas. Implementation of the following mitigation measure would reduce potential impacts to cultural resources to Tess than significant. Mitigation: Measures /Monitoring 15 -1 If, during the course of construction, cultural, archaeological or paleontological resources are uncovered at the site (surface or subsurface resources) work shall be; halted immediately within 50 meters : (150'feet) of the find until it can be evaluated 'bya qualified professional archaeologist. The City of Petaluma Planning Division and a qualified archaeologist,.(i.e.., an.archaeologist:registered with the Society of Professional Archaeologists) shall be immediately contacted by the responsible individual presenton =site. When contacted, Community Development Department staff and the archaeologist shall immediately visit the site to determine the extent of the resources and to develop proper mitigation measures required for the discovery. 16. Agricultural 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 Farmland 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 Williamson Act.contract? C. Involve other changes in the existing environment which, due to their location or nature, could result in conversion. of Farmland, to non - agricultural use? X V Discussion: In the past, the site was .used as pastureland and for hay production, and more recently,, a portion of the site was used to stockpile fill material from nearby construction sites: ,However, the project site is not currently used for agriculture and has not been used productively for at.least the last five years. Land must have been used for agricultural production at some time during the two prior update cycles of the Farmland Mappingand Monitoring Program of the California Resources. Agency (FMMP), each of which covers a two -year period, to be ,classified as Prime Farmland, Unique Farmland, or Farmland of Statewide Importance. The map of Sonoma County Important Farmland — 1998, prepared by California Resources Agency, identifies the project site as "Farmland of Local Importance ". Furthermore, the site's "Study .Area" zoning 'designation indicates that something other than an agricultural use is for the property. The site is not subject to a Williamson Act contract. • • Project implementation would not relocate or affect the area's agricultural infrastructure (farm and feed supply stores veterinarians, and other agriculturally related businesses) which, in turn could discourage' or make infeasible: continued • agricultural use of other property in the area. Therefore, impactsto agricultural resources would be less than significant. Mitigation Measures/Monitoring Not applicable: Page 33 , Southgate .initial Study Page 34 17.
