A RESOLUTION OF THE CITY OF PETALUMA CERTIFYING THE ADEQUACY OF
THE FINAL S>(JPPLEMENTAL ENVIRONMENTAL IMPACT REPORT AND
ADOPTING SPECIFIC FINDINGS REGARDING ENVIRONMENTAL IMPACTS AND
MITIGATION MEASURES FOR THE TWIN CREEKS RESIDENTIAL PROJECT
WHEREAS, the California Environmental Quality Act provides that all local agencies
prepare or cause to be prepared, an Environmental Impact Report (EIR), for any project
intended to be carried out or approved, which may have a significant effect on the
environment and that said local agency shall certify the adequacy of the EIR; and
WHEREAS, the City Council of Petaluma certified an EIR on June 4, 1990 by Resolution
No. 90-182 for the Twin Creeks project, but denied the project without prejudice; and
WHEREAS, an application for a revised Twin Creeks project which attempted. to respond
to `the concerns of the original EIR was submitted in August of 1990 and was deemed
complete in February of 1991; and
WHEREAS, an Initial Study of the revised Twin Creeks project indicated that changes to
the project would require important revisions of the previously certified EIR due to the
involvement of new potential significant environmental impacts not considered in the
previously certified EIR; and
WHEREAS, because only minor additions or changes to the Traffic/Circulation,
Hydrology/Flooding, Biotic and Visual Chapters would be necessary to make the previous
EIR adequately apply to the revised project, a Draft Supplemental Environmental Impact
Report (DSEIR) was prepared and published in October of 1991; and
WHEREAS, the Planning Commission, after holding two public hearings on November 12,
1991 and December 10, 1991, recommended that the DSEIR be forwarded to the City
Council for final Certification together with comments made at the public hearings and
responses thereto based on the findings and subject to the mitigations listed in the staff
report dated December 10, 1991 and forwarded to the City Council on December 16, 1991;
and
NOW, THEREFORE, BE IT RESOLVED by the Petaluma City Council that the DSEIR,
and written and oral comments received thereon, together with a list of persons,
organizations and public agencies commenting and the responses to those comments, are
hereby determined to constitute the Final Supplemental Environmental Impact Report
(FSEIR) for the Twin Creeks residential project; and
BE IT FURTHER RESOLVED that the Petaluma City Council, in connection with the
certification, approval and adoption of the FSEIR on said project, hereby makes the
following findings pursuant to CEOA Guidelines Section 15091:
Reso. 92-11 NCS
Nes. No . .............................. N.C.S.
A. A potential impact relating to Planning Policy was identified as follows:
1. The revised plan is deficient in providing a mix of architectural treatment.
The identified impact will be mitigated to a level of insignificance by the following
mitigation measure to be incorporated into the project:
1. The applicant shall provide 2, 3 and/or 4 bedroom units and create
architectural diversity with use of varying front-yard setbacks, exterior
material, window treatment and garage design subject to approval by
SPARC prior to final map approval. SPARC shall require the applicant to
provide alternate garage door locations by staggering placement of garages,
locating to rear or side of house, or siting perpendicular to street frontage.
B. Potential impacts relating to Traffic were identified as follows:
Extending Ellis Street to Madison will double the number of vehicles
utilizing the intersection. LOS will remain at A.
2. Site distances could be limited for vehicles entering internal streets from
driveways, particularly in front of units 27-31.
3. The turning radius within the cul-de-sac would restrict truck access.
4. Children Crossing Ellis anal Madison Street when walking to and from school
create potential pedestrian/vehicle conflicts in the area of McKinnley
Elementary School.
5. As identified in comments from Commissioner Tarr at the December 10th
Planning Commission meeting, and as further identified in comments from
Mr. George Vedders, the project will have the following impacts on residents
of the unimproved portions of Ellis Street:
a. The extension of Ellis street will result in additional traffic and noise
near the existing residents.
b. The owners Williams and Vedders will loose use of the Ellis Street
right-of-way as their driveway.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measures to be incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. The applicant shall provide stop sign at new Ellis Street approach to
Ellis/Madison intersection.
2. The final Landscaping Plan shall be designed to avoid landscaping in front of
units 27-31 which could block motorists line-of-site when entering Holly
Street.
Reso. 92-11 NCS
2
3. The final map shall be modified to prohibit curb parking on the cul-de-sac
and provide for parking in a landscaped parking island to discourage illegal
parking around the cul-de-sac.
4. a. The applicant shall be responsible for installation of warning signs
consistent with State of California Department of Transportation
Guidelines for school area pedestrian safety prior to the issuance of
building permits for the new homes. Appropriate signing includes a
fixed (non-flashing) yellow warning pedestrian sign and SCHOOL
sign located mid-block adjacent to McKinnley Elementary School on
Ellis and Madison Streets.
b. The applicant shall contact McKinnley School and assist the school in
establishing a crossing guard grogram for the school in the vicinity of
Madison and Ellis Streets subject to approval by the Administrators of
the Petaluma School District. The applicant shlal offer up-front
program funding to the School District for a minimum of 5 years.
5. a. The developer shall be responsible for installing a fence along the
property lines of those three parcels along the new portion of Ellis
Street subject to approval of the individual property owners.
b. The developer shall install curb cuts and driveway aprons for those
owners who will loose existing driveways subject to approval by the
individual property owners.
C. .Potential impacts relating to I-Iydrology were identified as follows:
1. Lots 13-17 of the proposed project may interfere with the right-of-way
requirements for the flood control and/or required riparian mitigation area
for the Corps of Engineers Petaluma River project.
2. Project plans depict a freeboard of 1.0 foot for the Washington Creeks
Bridge. SCWA criteria recommends 1.5 foot of freeboard.
3. Flooding as a result of a 100-year storm would be limited to low lying
portions of the roadway. Access would be limited to high-clearance vehicles.
No houses would flood during the 100-year event.
4. A portion of the project site is located in the 100-year floodplain and 100-
year food-way zone.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measures to be incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. a. The applicant shall eliminate lots 16 and 17 or re-configure the map
to provide no more than four lots in the area west of Holly Street. Lot
17 and a portion at the rear of lot 16 shall be left as openspace to
provide better visual and physical access to the river. The larger area
of the map to the east and north of Holly Street may be re-configured
to include not more than 40 lots for a map total of 44 lots. The
applicant shall post a sign visible from the public right-of-way and
Reso. 92-11 NCS
3
shall give written notice to all prospective homebuyers (until the area
is developed or converted to a mitigation area for the Army Corps
project) that the area in the vicinity of Lots 13 through 16 may be
developed with up to four homes.
b. The applicant shall delay construction of the lots in the area to the
west of Holly Street to avoid interference with the Corps Flood
Control Project. The applicant shall delay filing the final map for this
area until finalization of the Army Corps plans.
2. The improvement plans for the bridge crossing shall provide a recommended
minimum freeboard of 1.5 foot during a 100-year storm.
3. The tentative map and grading plan shall be modified to raise the roadway
elevation or the project will have to be postponed until after construction of
the Army Corps project.
4. a. Excavation at the Project site shall be of a volume no less than that
analyzed in applicant's hydraulic study; location of excavation should
be no further away from river than that analyzed in the hydraulic
study. This will comply with the City's Ordinance requiring "zero net
fill and a minimum 2-foot freeboard."
b. The applicant shall be required to maintain "no net fill" throughout
the construction process on areas of the site within the floodplain.
D. Potential impacts relating to Biotics were identified as follows:
1. Applicants plan depicts non-native, exotic plant species not suitable for
riparian enhancement.
2. As identified in the U.S. Fish and Wildlife letter dated November 20, 1991,
the project provides no restoration of the riparian habitat along the Petaluma
River.
3. Sidewalk location interferes with the proper function of the landscape buffer.
4. Portions of the landscape buffer along Washington Creek do not meet 20
foot width as recommended in the DEIR.
5. Extent of riparian mitigation for the Corps improvement project as required
by U.S. Fish and Wildlife is unknown.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measures to be incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. a. Landscape plans shall reflect plant species which are normally .found
in a natural riparian community, such a a Fremont Cottonwood,
Alder, Sycamore and other species suggested in the EIR and SEIR.
Exotics should not be used.
Reso. 92-11 NCS
4
b. The species recommended by the Fish and Wildlife Service should be
incorporated into the applicants landscape plan.
2. The applicant shall submit a restoration plan for that portion of the project
along the Petaluma River, subject to approval by the Department of Fish and
Game prior to approval of the final map.
3. The landscape plan shall be modified to realign sidewalk to outer edge of the
buffer with adequate space left between the edge of the sidewalk and the
curb for a planter strip when feasible.
4. The landscape plan shall provide an average 20-foot landscaped buffer along
Washington Creek. At no point shall the buffer be less than 15 feet.
5. The applicant shall delay construction of lots 13-17 to avoid interference with
the. Corp Flood Control Project. The applicant shall delay filing the final map
for this area until finalization of the Army Corp plans.
E. A potential Visual impact was identified as follows:
Views for motorists and pedestrians will continue to be that of two-car
garages and garage doors of similar design.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measure to be incorporated into the project:
Where feasible, SPARC shall require the applicant to provide alternate
garage door locations by staggering placement of garages, locating to rear or
side of house, or siting perpendicular to street frontage.
F. A potential Services/Utilities impact was identified as follows:
1. As identified in a letter from George Larson, Waste Management Specialist
for the California Environmental Protection Agency, the project will result in
an increase in the amount of solid waste which will cumulatively impact
landfill capacities.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measures to be incorporated into the project:
a. The developer shall provide information to the residents about
recycling services in the project area and suggest that residents recycle
glass, metal, paper, cardboard and other materials to the maximum
extent possible.
b. Insulation and other products made of recycled products shall be
considered for use in construction of the subdivision. Design of
residential units shall consider the inclusion of recycle storage areas.
c. The developer shall suggest to residents, through the distribution of
literature or some other method, that they use recycled materials to
the extent possible.
Reso. 92-11 NCS
1 BE IT FURTHER RESOLVED that the Petaluma City Council, in reference to the
2 impacts and mitigations identified in the previously certified FEIR on said project, hereby
3 makes the following findings:
A. Potential impacts relating to Land iJse/Planning Policy, not necessarily included in
the scope of the SEIR but identified in the FEIR, are as follows:
1. Land Use
a. New houses would create an architectural contrast to the Wilmington
Drive neighborhood.
b. Visual encroachment would occur with the placement of two-story
houses adjacent to existing single story neighborhood.
c. Views of the riparian corridors would be partially blocked.*1
2. Zoning
a. Findings must be made for approving a PUD. Considerations of a
single access, protection of natural and scenic qualities,
appropriateness of project in relation to adjacent properties and
adequate landscaping/screening must be given in making the
findings.*
3. Growth Management Ordinance:
a. The project could not be developed until improvements to the
Wilmington sewer pump station have been completed.*
b. The proposed project does not provide a housing mix, both in type
and affordability.
4. General Plan:
a. The proposed project does not conform with Housing Policies 1 and
11 regarding mix of housing types and provided for low/medium
incomes.
b. The proposed project does not comply with General Plan land use
designation calling for flexibility in site design and unit type. Site-
design reflects a standards subdivision and house styles are very
similar.
c. Project plans do not provide for enhancement of the riparian
corridors as called for in the general Plan. Influx of people into the
area could impact the creek corridor with dumping of household trash
and accelerating bank erosion with the increase m pedestrian traffic
along the creek.
1 * indicates impacts which have been partially or fully
mitigated by the redesign of the project.
Reso. 92-11 NCS
6
1 d. Community Charter Policy 15 calls for 10 percent of units in a
2 development to be significantly different in architectural style. The
3 project does not comply with this policy as the units are very similar.
4
5 e. Policy 23 calls for a definition of new neighborhoods. Project plans
6 propose a solid wooden fence which is unattractive and uninviting.
7
8 The above policy impacts identified in the FEIR will be mitigated to a level of
9 insignificance by the following mitigations measures which have been or will be
10 incorporated into the project:
11
12 (Note: Mitigations below correspond to the impacts as enumerated above)
13
14 1. a. The houses shall be designed to be compatible with the existing
15 neighborhood and to provide a mix of single and two story houses.
b. As reemphasized in the SEIR, the development plan should increase
the number of single story houses on lots adjacent to the existing
neighborhood. The impact on the existing neighborhood has been
partially mitigated by the revised project which shows greater rear
yard setbacks for these lots than first proposed.
c. This impact has been mitigated to a level of insignificance because the
project has been redesigned to provide a single loaded street which
opens up views of the riparian corridors.
2. a. A,s reemphasized in the SEIR, the project shall be re-designed to
provide a more diverse mix of housing styles in order to make the
necessary findings to approve the PUD. This impact has been
mitigated somewhat by the redesign of the project to provide a
secondary access which would allow the City Council to make the
required PUD findings relating to access to the PUD site.
3. a. This impact has been mitigated to a level of insignificance through the
implementation of interim improvements to the Wilmington Pump
Station by the City.
b. The applicant shall be required to pay low and moderate income
housing in-lieu fees of an amount to be determined according to the
schedule established by City Council Resolution No. 84-199 N.C.S., or
make alternative arrangements to meet low and moderate income
housing provision requirements of the Petaluma General Plan,
subject to approval of the City and prior to Final Map approval.2
4. a. The applicant shall be required to pay low and moderate income
housing in-lieu fees of an amount to be determined according to the
schedule established by City Council Resolution No. 84-199 N.C.S., or
make alternative arrangements to meet low and moderate income
2 Those mitigations in bold are those still necessary to
mitigate impacts identified in the FEIR. These mitigations
plus those included from the FSEIR are included as
conditions of approval of the PUD Unit Development Plan.

housing provision requirements of the Petaluma General Plan, subject
to approval of the City and prior to Final Map approval.
b. As reemphasized in the SEIR, the project shall be re-designed to
provide a more diverse mix of housing styles.
c. 1Vlitigations suggested in the 13iotic section should be implemented for
the project to comply with open/space waterways policies.
d. As reemphasized in the SEIR, the project shall be re-designed to
provide a more diverse mix of housing styles.
e. The applicant shall provide for an attractive sign or bollard or other
landscaped monument at the sites entrance.
B. Potential impacts relating to Traffic/Circulation, identified in the FEIR, are as
follows:
1. Project streets would be 30-feet wide combined with on-street parking.
Parking on both sides of the street would restrict two-way traffic.*
2. Pedestrian/vehicle safety conflicts may occur with the increase in traffic.
3. As identified in comments from Tom Hargis, Director of Engineering for the
City of Petaluma dated March 23, 1990, the lack of a second access results in
unmitigatable circulation problems.*
The above impacts identified in the FEIR will be mitigated to a level of
insignificance by the following mitigations measures which have been or will be
incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. This impact has been mitigated to a level of insignificance because the street
width in the revised project has been increased to 32' curb-to-curb, the
minimum width permitted for a residential street with parking on both sides.
2. As reemphasized in the SEIR, the applicant shall be responsible for
installation of warning signs consistent with State of California Department
of Transportation Guidelines for school area pedestrian safety prior to the
issuance of building permits for the new homes. Appropriate signing
includes a fixed (non-flashing) yellow warning pedestrian sign and SCHOOL
sign located mid-block adjacent to McKinnley Elementary School on Ellis
and Madison Streets.
3. This impact has been eliminated through the redesign of the project to
provide a secondary access at Ellis Street.
C. Potential impacts relating to Hydrology/Flooding/Water Quality, identified in the
FEIR but not necessarily included in the scope of the SEIR, are as follows:
1. A portion of the project site is located in the 100-year floodplain zone and
100-year food-way zone.
Reso. 92-11 NCS
8
2. Runoff from the proposed site is to be conveyed through conventional storm
drains under the streets and discharged into the Petaluma River and
Washington Creek. The subdivision would increase runoff flow that could
result in flooding.
3. The conversion of the project site from open space to residential use would
increase the potential for surface water pollution impacts.
4. Sedimentation and erosion impacts from the project could occur during
grading of the site or at storm drain discharge points along the Petaluma
River and Washington Creek.
5. As indicated in a Letter from the Army Corps dated 4/9/90 included in the
FEIR, the Army Corp project may require widening the channel in the
vicinity of the project. The project may interfere with the ability of the Army
Corp to complete the flood control project. The Planning Commission
recommended at their April 24, 1990 meeting that project approval be
postponed until such time as the final Army Corp of Engineering project is
determined.*
The above impacts identified in the FEIR will be mitigated to a level of
insignificance by the following mitigations measures which have been or will be
incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. Consistent with the cities "no net fill" policy, the fill proposed at the project
site shall be balanced with an equal volume of excavation in the over-bank
areas of the Petaluma River.
2. The project storm drain system shall conform to the criteria established by
SCWA and the City of Petaluma. The storm drain shall be sized to
accommodate runoff from existing homes to the north of the site. The
discharge point shall be designed so as not to obstruct flow in the river or
the creek.
3. The applicant should attempt to reduce the amount of runoff from paved
areas to help reduce the off-site transport of urban pollutants.
4. Construction-related impacts shall be mitigated by limiting the grading to
the dry season (May-October) when flows and run-off potential are lowest.
Erosion control shall be provided in conformance with the city's erosion
control standards.
5. a. As reemphasized in the SEIR, those parcels adjacent to Lynch creek
and the Petaluma river may interfere with the Army Corp project and
development of these lots (now numbered 13-17) shall be deferred
until the finalization of the Army Corps plans.
b. Conflicts with the Army Corps project have been eliminated
somewhat through the redesign of the project. The Army Corps was
asked to provide the City with the most land consumptive solution to
mitigate a 100 year flood and provide adequate Riparian Setbacks.
The project has been redesigned to avoid the Army Corps most land
Reso. 92-11 NCS

consumptive alternative, a 220' wide area along this portion of the
Petaluma River.
D. Potential impacts relating to Noise, not included in the scope of the SEIR but
identified in the FEIR, are as follows:
1. Short term noise impacts would occur during grading and construction
activities.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measures to be incorporated into the project:
1. a. Construction operations shall be limited between 5:00 pm and 8:00
am and on weekends.
b. All construction and grading equipment shall be properly muffled.
c. The developer shall provide temporary shielding between the noise
source and the receiver.
d. The developer shall reduce the level of backup beepers on heavy
equipment.
E. Potential impacts relating to Geology/Soils, not included in the scope of the SEIR
but identified in the FEIR, are as follows:
1. Major earthquakes along faults within the San Francisco Bay region are
likely to produce strong ground shaking at the project location with a
maximum probable earthquake on the San Andreas fault estimated to be a
Richter 8.3 magnitude.
2. Intense rainfall could produce creek flows that can erode banks and strong
ground shaking from earthquakes can create bank instability. Construction
grading could load the tops of banks to cause slope failure.
3. Plastic clay soils are present at the site with a high potential for
expansion/contraction during changes in moisture content. This would result
in cracking and differential movement damage to foundations, concrete slabs
and pavements.
4. Erosion is accelerated and increased in an area by grading associated with
development. Following construction, eroding soil can clog drainages and
adversely divert instability and additional erosion.
The identified impacts will be mitigated to a level of insignificance by the following
mitigation measures to be incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. The applicant shall incorporate seismic design parameters in construction,
including foundations and structures, graded slopes, and retaining walls.
2. The potential for slope instability shall be mitigated through engineering
design and construction.
Reso. 92-11 NCS
10
3. The use of expansive soils .for use in structural fill would have to be
evaluated in geotechnical investigations.
4. Construction-related impacts shall be mitigated by limiting the grading to the
dry season (May-October) when flows and run-off potential are lowest.
Erosion control shall be provided in conformance with the city's erosion
control standards.
F. Potential impacts relating to Biotics, identified in the FEIR but not necessarily
included in the scope of the SEIR, are as follows:
1. Increased pedestrian traffic by residents of the new development along the
north bank of Washington Creek adjacent to the project site would
accelerate bank erosion and siltation of the creek bed.*
2. Residents of the new development may dump household trash into the
creek/river corridor thus further degrading a diminished habitat.*
3. Garden chemicals and fertilizers used by project residents adjoining the
creek during periods of rainfall. This in turn would cause further impacts on
the filamentous algae stands and the mosquito fish populations.*
4. The barren bank areas of the north side of Washington Creek would present
a potentially dangerous situation to future residents of the project, especially
during the winter rainy period when the banks are slippery and the creek
flow is high.
5. If a culvert landfill crossing is used instead of a a spanning bridge structure
across Washington Creek, a segment of potential riparian bank area could be
lost due to the increased flow rates through the culvert, resulting in the loss
of vegetation along the bank. This would also require a Streambed
Alteration Permit.*
6. As indicated in the letter from the Department of Fish and Game dated
April 4, 1990 and included in the FEIR the project may impede the
mitigation efforts by the Army Corps for the flood control project.
The above impacts identified in the FEIR will be mitigated to a level of
insignificance by the following mitigations measures which have been or will be
incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1&2. These impacts have been mitigated by a redesign of the project to align the
roadway along Washington Creek and the Petaluma River and provide for a
continuous buffer averaging twenty feet in width but not less than fifteen feet
at any one point, between the toe of the north bank and the edge of the
property line.
3. This impact has been mitigated to a level of insignificance by realigning the
street and providing for a landscape buffer. Storm drainage outfalls have
been re-aligned so that they all flow into the Petaluma River which can
sustain toxic outflows better than Washington Creek.
Reso. 92-11 NCS
11
4. In keeping with SCWA policy, the slope of the north bank of Washington
Creek shall be hydro-seeded with a mixture of annual grasses.
5. This impact has been mitigated to a level of insignificance by the design of
the bridge which provides for a spanning bridge structure with a single
support in the center. Proposed excavation along the banks of the creek in
the area of the bridge will alleviate impacts from the center support.
6. a. As reemphasized in the SEIR, the development of the lots adjacent to
Lynch Creek and the Petaluma River shall be delayed until
finalization of the Army Corps plans. If necessary, these lots shall be
eliminated if the area is required to mitigate the Corps project's
biological impacts.
b. The applicant shall coordinate the landscaping of the "Public Use
Area" with Fish and Game to develop a riparian enhancement
restoration program that will satisfy the needs of DFG and meet the
goals of the City to provide for pedestrian trails along the creeks and
river.
G.
Potential impacts relating to Services and Utilities, identified in the FEIR but
not included in the scope of the SEIR, are as follows:
Law Enforcement/Fire Protection
a. The site only includes one entrance/exit, therefore restricting
emergency vehicles if the access is blocked.*
b. Foot traffic along Washington Creek and the Petaluma River in the
area may lead to a problem with burglaries, trespassing, prowling and
vandalism to the homes bordering the creek and river areas. Visibility
to the rear of these homes for the patrolling officer is non-existent and
access would be limited.*
2. Schools
a. The proposed project would increase the OASUSD and PSD
enrollment. Portable classrooms and additional staff may be required
at the elementary and secondary schools levels.
The above impacts identified in the FEIR will be mitigated to a level of
insignificance by the following mitigations measures which have been or will be
incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. a. This impact has been mitigated to a level of insignificance by the
redesign of the project to include a secondary access across
Washington Creek at the end of Ellis Street.
b. This impact has been mitigated to a level of insignificance by the
redesign of the project to provide for a single loaded street along
Washington Creek and the Petaluma River.
Reso. 92-11 NCS
12
2. a. The developer shall be responsible to pay school impact fees to fund
necessary capital improvements.
H. Potential impacts relating to Archeology, identified in the FEIR are as
follows:
1. Although an archaeological survey did not reveal cultural deposits on the
site, any prehistoric deposits by be buried because of the proximity of the site
to the aver.
2. The structures on the site, particularly the Buchanan house, may be of
historic value.
The above impacts identified in the FEIR will be mitigated to a level of
insignificance by the following mitigations measures which have been or will be
incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. An architectural historian shall be retained to assess the historic value of
the structures on the site, particularly to turn of the century Buchanan
home. If it is found that the houses are of historic value, they shall not be
demolished and either retained on the .site or moved to another site.
2. In the event that archaeological remains are encountered during grading,
work shall be halted temporarily and a qualified archaeologist shall be
consulted for evaluation of the artifacts and to recommend future action.
The local Indian community shall also be notified and consulted in the event
any archaeological remains are uncovered.
I. Potential impacts relating to Visual/Aesthetics, identified in the FEIR are as
follows:
1. Wilmington Drive residents would loose their outdoor privacy with the
development of two-story homes overlooking the backyards along the eastern
property line.*
2. Project plans lack architectural variety and diversity in the siting of the
homes.*
The above impacts identified in the FEIR will be mitigated to a level of
insignificance by the following mitigations measures which have been or will be
incorporated into the project:
(Note: Mitigations below correspond to the impacts as enumerated above)
1. As reemphasized in the SEIR, the development plan should increase the
number of single story houses on lots adjacent to the existing neighborhood.
The impact on the existing neighborhood has been partially mitigated by the
revised project which shows greater rear yard setbacks for these lots than first
proposed.
Reso. 92-11 NCS
13
2. This impact has been somewhat mitigated by the redesign of the project to
provide for a single loaded street. As reemphasized in the SEIR, the project
shall be re-designed to provide a more diverse mix of housing styles and
changes to garage locations.
BE IT FURTHER RESOLVED that potential alternatives to the project were identified
as follows:
1. No Project
2. Lower Density Residential
3. Alternative Site
BE IT FURTHER RESOLVED~that in accordance with Section 21081(c) of the California
Environmental .Quality Act (CEQA) and CEOA Guidelines Section 15091(a1f31 the above
alternatives are found to be infeasible due to economic, social, technological and other
factors as follows:
No Project. This alternative would be contrary to the General Plan
designation of the site for urban residential development. The site does not
posses constraints or unique scenic qualities or natural amenities which
would favor its use for public open space over urban. use. It is unlikely that
the City would be interested in future acquisition of the site as there is
currently adequate park-land and no proposed park-land which are more
appropriate for such use.
2. Alternative Site. A nearby site along the Petaluma River was identified by
the EIR as having similar land use planning, geology/soils, drainage, traffic,
services and biotics impacts. Additional impacts relating to the accessibility
of the site, noise impacts on the site from the railroad and Highway 101, air
quality impacts for a nearby Tallow Plant and impacts relating to the view
from the site of adjacent commercial uses and the railroad. In general the
alternative site was identified as having more impacts and requiring more
mitigations than the project site.
BE IT FURTHER RESOLVED, in reference to the above alternatives, that City Council
Resolution No. 90-183 N.C.S., denying the Proposed. Rezoning and PUD Development
Plan, found that substantial redesign of the project would be necessary to justify the
rezoning to PUD. In the most recent redesign of the project, the lower density alternative
was chosen in an attempt to address impacts relating to Land Use and Planning Policy,
Traffic/Circulation, Visual/Aesthetics, Hydrology, and Biotics.
BE IT FURTHER RESOLVED that implementation of the specific findings of mitigation
contained herein which have not already been incorporated into the revised project, shall
be accomplished through the conditional approval of the PCD Development Plan for the
Twin Creeks project and hereby incorporates, by reference Resolution No. 92-16 N.C.S.
setting forth said conditional approval.
IN CONCLUSION, BE IT FURTHER RESOLVED that the Petaluma City Council does
hereby certify the Final Supplemental Environmental Impact Report on said project, and
in connection with this approval makes the following findings pursuant to State and local
guidelines:
Reso. 92-11 NCS
14
The FSEIR for the Twin Creeks project adequately evaluates the impacts on the
environment, not addressed in the FEIR or mitigated through the required redesign
of the project, and the FSEIR has been completed in compliance with the California
Environmental Quality Act (CEQA); and
2. The Planning Commission has reviewed and considered the information in said
Supplemental Environmental Impact Report; that qualified consultants have
prepared the Final .ENVIRONMENTAL Impact report; and that the Planning
Commission has reviewed the ENVIRONMENTAL documents applicable to the
proposed project and made recommendations thereon; and
3. The FSEIR has been presented to the decision making body of the Lead .Agency,
the City Council of the City of Petaluma, and the City Council will review and
consider the information contained in the FSEIR prior to approving the Twin
Creeks project.
4. Required changes to the project, outlined by the preceding mitigations, and
incorporated into the conditions of approval for the Tentative Map and PUD
development Plan, will avoid or substantially lessen the environmental effects
identified in the FEIR and FSEIR; and
5. On the basis of the FEIR and the FSEIR, there is no substantial evidence that the
project as mitigated, will have a significant effect on the environment.
