NOW THEREFORE BE IT RESOLVED by the Petaluma Planning Commission as follows:
1. The above recitals are hereby declared to be true and correct and are incorporated into the
resolution as findings of the Petaluma Planning Commission.
2. The potential environmental impacts of the Scott Ranch Project, including the proposed Vesting
Tentative Subdivision Map, were fully analyzed in the Scott Ranch Final EIR (SCH# 2004072137)
Planning Commission Resolution No.2022-15 Page 3
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
containing all the requirements of CEQA Guidelines Section 1532, inclusive of the RDEIR,
references, appendices, and all attachments thereto.
3. Approval of the proposed Vesting Tentative Subdivision Map as outlined below is contingent
upon the City Council's certification of the FEIR and including adoption of the Mitigation
Monitoring and Reporting Program.
4. The Planning Commission recommends the City Council approve the Vesting Tentative
Subdivision Map for the Scott Ranch Project based on the findings made below and subject to
the conditions of approval attached as Exhibit 1 hereto and incorporated herein by reference:
A. The proposed map is consistent with the General Plan in that it provides a residential project
on a property designated for residential uses with a density range of 0.6 to 2.5 dwelling units
per net acre.
B. The proposed tentative map as designed and conditioned, together with provisions for its
design and improvements, is consistent with the General Plan in that the project has a
density of 10.09 dwelling units per net acre. The project will also preserve the Kelly Creek
riparian area and will implement development consistent with Implementing Zoning
Ordinance Chapter 16 for development in the West Hills subarea. The map will not be
detrimental to the public health, safety, or welfare in that adequate public facilities exist or
will be installed, including roads, sidewalks, water, sewer, storm drains, and other
infrastructure.
C. The site is physically suitable for the density and the type of development proposed in that
the proposed Scott Ranch PUD provides for clustered residential development at the
minimum allowable density to meet the Very Low Density Residential land use designation
and utilizes access from existing roadways. The project is laid out to cluster the proposed
residential component on eleven acres on either side of Windsor Drive and including five
acres of private open space. This layout provides for preservation and designation of the
remaining 47 acres, including the identified red legged frog habitat, riparian corridor along
Kelly Creek, and historic vista of the red barn complex, under a conservation easement and
dedication to Sonoma County Regional Parks for expansion of neighboring Helen Putnam
Regional Park.
D. The site is physically suitable for the proposed density with the implementation of the
proposed mitigation measures recommended in the project's Final Environmental Impact
Report. The 58.66 acre project site has adequate area to support the proposed 28 residential
units clustered on 11 acres adjacent to Windsor Drive while preserving the majority of the site
for preservation in perpetuity as publicly accessible parkland and open space.
E. The design of the subdivision and the proposed improvements will not cause substantial
environmental damage or substantially and avoidably injure fish and wildlife or their habitat
in that the Final Environmental Impact Report provided mitigation measures to reduce
identified potential impacts on environmental resources to less than significant levels. All
identified mitigation measures are included as conditions of approval to ensure
implementation through the project.
F. With implementation of the project's mitigation measures associated with the project's Final
Environmental Impact Report, no serious public health problems would be caused as a result
of the proposed project or Vesting Tentative Subdivision Map.
G. The design of the subdivision and the type of improvements will not conflict with easements,
acquired by the public at large, for access through or use of property within the subdivision
in that the project is proposing off site improvements including a round about at the
Planning Commission Resolution No.2022-15 Page 4
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
intersection of Windsor Drive and D Street and an approximately 800 foot sidewalk gap
closure on the east side of D Street north of the project site, both of which will improve
access in the area for multiple modes of travel. Additionally, the project has been designed
to provide adequate emergency vehicle access. Existing easements will be preserved or
realigned to mesh with the subdivision design.
H. The proposed Scott Ranch Vesting Tentative Subdivision Map complies with the requirements
of Chapter 20.16, Tentative Subdivision Map, of the Subdivision Ordinance and with the
Subdivision Map Act as further described in the staff report.
I. The proposed Scott Ranch Vesting Tentative Subdivision Map complies with the requirements
of IZO Section 16.070 as follows:
a. The minimum parcel size of the 28 residential lots has been modified to cluster and
minimize development footprint due to the unique characteristics of the site. The
proposed lot layout responds to site conditions and complies with the General Plan
goals and policies related to the clustering of development. The proposed 28
residential lots remain consistent with the minimum density range of the very low
density residential land use designation and remains within the limitations prescribed
in IZO Section 16.070.D.
b. The density of the proposed project is consistent with the lowest end of the General
Plan density range for the site.
c. All sites created by the VTSM is subject to the development standards as outlined in
the Scott Ranch PUD Guidelines and Unit Development Plan.
J. The proposed Scott Ranch Vesting Tentative Subdivision Map implements the objectives for
hillside development as outlined in IZO Chapter 16 and including the following:
a. The proposed project does not develop on open ridgelines.
b. The clustering of residential development on 1 1 acres of the 58.66 acre site along
Windsor Drive in order to protect the majority of the site and its unique biological
resources for preservation in perpetuity.
c. The clustering of residential development minimizes the development footprint,
protects natural features, maximizes tree protection, and preserves unique habitat by
locating structures away from these assets.
d. The proposed siting of the residential units and proposed architectural design is
consistent with existing development in the surrounding area and has minimized the
profile of the built environmental to minimize environmental impacts and cluster the
development in a small portion of the site.
e. By clustering the development the project minimizes the development footprint and
associated alteration of the hillside topography.
f. The proposed project clusters the residential units on smaller lot sizes to meet
minimum density standards while minimizing development footprint and maximizing
open space.
g. The proposed development is consistent with neighboring residential development in
the immediate vicinity.
h. The clustering of residential units allow for preservation of existing trees on the site.
Planning Commission Resolution No.2022-15 Page 5
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
i. The proposed development is clustered outside of the 30 percent slope areas to the
extent possible.
j. The project is designed to reduce erosion and landslide hazards on the site.

on CRLF. The Final CRLFMP shall be prepared in consultation with and be approved by the USFWS,
CDFW, USACE, and City, and shall provide for the protection, replacement, and management of
habitat for CRLF affected by proposed development and public open space use on the project
site. The Final CRLFMP shall be required as a condition of approval for the project Tentative Map,
and shall include the following components and meet the following standards:
Preconstruction and Construction Avoidance Provisions
a) Preconstruction surveys shall be conducted by a Service-approved biologist prior to any
grading or major vegetation clearance to ensure that no individual CRLF are lost during
construction. These preconstruction surveys shall also verify the presence or absence of
Planning Commission Resolution No.2022-15 Page 10
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
occupied dens of American badger, burrows of western burrowing owl, and individuals of
western pond turtle and foothill yellow-legged frog in the remote instance individuals were to
disperse onto the site in advance of construction-related disturbance. The Final CRLFMP
shall: 1) describe in detail the survey approach and methodology, and 2) specify that grading
or vegetation clearance may not occur in any area where individual CRLF, American
badger, western burrowing owl, western pond turtle, and/or foothill yellow-legged frog
are located until such time as the individual has either moved out of the disturbance zone or
has been physically relocated by a Service-approved biologist legally authorized to
handle the species. Any relocation effort for CRLF, American badger, western burrowing owl,
western pond turtle and/or foothill yellow-legged frog shall be formulated in consultation
with and approved by CDFW and USFWS and shall be implemented by a qualified biologist.
b) All project-related vegetation clearing and grading activities within potential habitat for
CRLF shall be monitored by a Service-approved biologist. The Final CRLFMP shall specify the
duties of the Service-approved biologist.
c) All construction personnel shall be trained in CRLF identification, habitat description, legal
protective status, construction restrictions, and procedures to avoid unnecessary disturbance
to potential habitat or incidental take of these species. The Final CRLFMP shall describe
this training program.
d) Exclusionary fencing shall be installed prior to grading or major vegetation clearance
where appropriate to keep CRLF out of construction areas. The Final CRLFMP shall
identify where such fencing is to be installed and provide procedures for fence installation,
monitoring, and maintenance. The Final CRLFMP shall require that the exclusionary fencing be
installed under the direct supervision of a Service-approved biologist and shall be
maintained during the course of construction activities on the site.
e) If necessary, identify the locations for use of permanent exclusionary fencing or other barriers
to prevent and minimize dispersal of CRLF into areas with concentrated human activity,
based on input from the USFWS and CDFW. This may be particularly important at locations
along segments of the multi-use trail to the south of Kelly Creek or parking lot and
staging area on the east side of the D Street tributary, to prevent the movement of individual
frogs into areas, of intensive bike, pedestrian and vehicle activity. If used, the
permanent exclusionary fencing/barriers shall be designed and installed during project
construction under the supervision of a Service-approved biologist.
f) Appropriate signage shall be designed and installed to restrict unauthorized human
access into essential habitat areas for CRLF during construction.
Habitat Avoidance and Mitigation Provisions
g) Avoid development and associated direct and indirect impacts on CRLF in accordance
with project revisions required as part of the consultation review and approval process
with CDFW and USFWS. Compensatory mitigation shall be provided at a minimum of 3:1
for permanent impacts and 1:1 for temporary impacts to CRLF habitat. This may be
accomplished through permanent protection and establishment of two conservation
easements or other mechanisms of suitable habitat on-site and off-site, where necessary to
achieve the minimum compensatory mitigation requirements or as otherwise required by
the CDFW and USFWS.
h) Control unauthorized access to the on-site stock pond and open space in the southwestern
portion of the project site to protect these essential habitat features for CRLF. Install
fencing and interpretive displays and restrictive signage along all trail systems as necessary to
control access from the proposed multi-use trails and other locations where unauthorized
access is likely.
i) Where disturbance and improvements within essential habitat and movement corridors
cannot be completely avoided and on-site mitigation is considered insufficient by the
CDFW and USFWS, the loss shall be mitigated by permanently preserving similar quality
habitat known to support CRLF at off-site locations preferably in the Petaluma vicinity of
Planning Commission Resolution No.2022-15 Page 11
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
Sonoma County, as negotiated with the regulatory agencies. It is possible that the
mitigation location, whether on-site or possibly off-site as well, could be used to achieve
mitigation for other biological and wetland impacts, depending on its habitat
characteristics, provisions for habitat creation and/or enhancement defined as part of the
Final CRLFMP, and negotiations with the CDFW and USFWS.
j) Identify methods to minimize the potential for harassment or take of listed and non-listed
species as a result of increased human activity associated with development and open
space use of the site. This shall include an educational program for future residents and
visitors, fencing and interpretive signage at access points into natural open space, use of
sensitive grade changes, culverted under-crossings, and bridged overcrossings in uplands
where roadways or trails bisect movement corridors, and possible use of permanent
exclusionary fencing.
Habitat Connectivity and On-Site Management Provisions
k) Define methods to provide connectivity for CRLF between open space areas on site and to
the surrounding undeveloped lands to the west, south, and east.
1) Provide for permanent protection and adaptive management of open space lands (both on-
site and possibly off-site) intended to function as potential habitat for CRLF
26. Mitigation Measure 1310-1c: Any active nests of raptors or other birds protected under federal and
state regulations in the vicinity of construction shall be avoided until young birds are able to leave
the nest (i.e., fledged) and forage on their own. Avoidance may be accomplished either by
scheduling grading, vegetation removal and demolition activities during the non-nesting period
(September 1 through January 31), or if this is not feasible, by conducting a pre-construction survey
for raptor and other bird nests. Provisions of the pre-construction survey and nest avoidance, if
necessary, shall include the following:
a. To avoid "take" of barn owls in the large barn, any relocation or restoration work shall be
initiated in the non-nesting period or shall be performed in conformance with the pre-
construction survey procedures detailed below.
b. If grading is scheduled during the active nesting period (February 15 through August 31), a
qualified wildlife biologist shall conduct a pre-construction nest survey no more than 15 days
prior to initiation of grading to provide confirmation on presence or absence of active nests in
the vicinity.
c. If active nests are encountered, species-specific measures shall be prepared by a qualified
biologist and implemented to prevent abandonment of the active nest. At a minimum, grading
and vegetation removal in the vicinity of the nest shall be deferred until the young birds have
fledged or are no longer dependent on the nest. A nest-setback zone shall be established within
which all construction-related disturbances shall be prohibited. These are typically at least 300
feet for all raptors and 100 feet for other birds protected under the Migratory Bird Treaty Act and
State Fish and Game Code, unless site-specific conditions allow for some variation from these
distances as determined by the qualified wildlife biologist in coordination with CDFW.The
perimeter of the nest-setback zone shall be fenced or adequately demarcated with staked
flagging at 20-foot intervals, and construction personnel restricted from the area.
d. If permanent avoidance of the nest is not feasible, impacts shall be minimized by prohibiting
disturbance within the nest-setback zone until a qualified biologist verifies that the birds have
either a) not begun egg-laying and incubation, or b) that the juveniles from the nest are
foraging independently and capable of independent survival.
Planning Commission Resolution No.2022-15 Page 12
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
e. Demolition of any existing buildings and removal of any trees shall also consider possible bat use
of the site, as defined below in Mitigation Measure BIO-1 d.
f. A survey report by the qualified biologist verifying that the young birds have fledged shall be
submitted to the Community Development Department of the City of Petaluma prior to initiation
of grading and vegetation removal in the nest-setback zone.
27. Mitigation Measure B10-Id: Measures shall be taken to avoid possible loss of bats during project
construction. Any buildings that are approved for demolition, rehabilitation, or relocation shall be
done using the following provisions:
a. Any buildings approved for removal shall be demolished between March 1 (or after evening
temperatures rise above 45 degrees F and/or no more than of rainfall within 24 hours occurs)
to April 15 or from August 31 to October 15 (or before evening temperatures fall below 45
degrees F and/or more than of rainfall within 24 hours occurs) to minimize the likelihood of
removal during the winter roosting period when individuals are less active and more difficult to
detect, and the critical pupping period (April 16 to August 30) when young cannot disperse.
b. Buildings shall be surveyed by a qualified bat biologist possessing a Memorandum of
Understanding with the CDFW no more than 2 weeks before demolition and/or relocation work is
undertaken to avoid "take" of any bats that may have begun to use the structures for roosting
subsequent to the assessments by Wildlife Research Associates (2004 and 2014). The buildings in
which roosting would be most likely to occur are the large two-story barn, hay barn, and garage
building.
c. If the pre-demolition survey reveals bats or bat roosting activity, all doors and windows shall be
opened and left open continually until demolition, relocation and/or rehabilitation work is to
begin. Additional recommendations may be made by the qualified bat specialist following the
pre-construction survey, including monitoring of demolition and/or relocation and other
measures to avoid take of individual bats.
d. A tree roost habitat assessment shall be conducted by a qualified bat biologist possessing a
Memorandum of Understanding with the CDFW of any trees that will be removed as part of the
project. The habitat assessment shall be conducted no more than 2 weeks prior to tree removal
and vegetation clearing. Additional detailed measures may be required based on the results of
the habitat assessment if evidence of bat roosting is observed. This may include supervision of
tree removal by the qualified bat biologist, and systematic removal of selected trees and major
limbs to encourage dispersal and avoid "take" of individual bats.
28. Mitigation Measure 1131O-2a: A detailed Landscape and Vegetation Management Plan (Plan) shall
be prepared by a qualified landscape architect in consultation with CDFW and a plant ecologist
experienced with native species. The Plan shall: 1) provide for re-establishment of grassland, riparian,
and oak woodland cover on graded slopes in open space areas; 2) incorporate mitigation
requirements to replace and enhance wetland habitat and provide for replacement of native trees
removed as part of the project; 3) provide for replacement of native grasslands lost as a result of
development and trail improvements; 4) identify unsuitable species which should not be used in
landscaping; 5) prevent the establishment and spread of introduced broom; and 6) specify long-
term management provisions to ensure re-establishment of native and ornamental landscape
improvements. Aspects of the plan shall include, but will not be limited to, the following:
a. Graded slopes in open space areas shall be reseeded with a mixture of native perennial and
annual grassland species to increase the diversity of the grassland cover. Suitable species to be
used in the seed mix include: California brome (Bromus carinatus), purple needlegrass (Stipa
pulchra), creeping wildrye (Elymus tritichoides), California poppy (Escscholtzia californica),
Planning Commission Resolution No.2022-15 Page 13
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
among others. Highly invasive non-native annuals, typically used for erosion control alone, should
not be used.
b. Landscaping and revegetation shall emphasize the use of native plant species along the fringe
of proposed development, and plantings in open space areas should be restricted to native
species. Suitable plant species for use in open space areas include: valley oak (Quercus lobata),
coast live oak (Quercus agrifolia), California buckeye (Aesculus californica), toyon (Heteromeles
arbutifolia), California rose (Rosa californica), creeping wildrye, and purple needlegrass, among
other species.
c. Use of non-native, invasive species which may spread into adjacent undeveloped open space
areas shall be prohibited in landscaping plans. Unsuitable species include: blue gum eucalyptus
(Eucalyptus globulus), acacia (Acacia spp.), pampas grass (Cortaderia selloana), broom (Cytisus
spp.), gorse (Ulex europaeus), bamboo (Bambusa spp.), giant reed (Arundo donax), periwinkle
(Vinca spp.), English ivy (Hedera helix), and German ivy (Senecio milanioides). This prohibition
shall be included in the CC&R for the proposed residential subdivision, as well as undeveloped
areas to be retained as permanent open space.
d. Graded slopes and areas disturbed as part of the project shall be monitored to prevent
establishment and spread of introduced broom species (Cytisus spp and Genista
monspesullana). This should apply to the lands on the project site that are placed under a
conservation easement as well as common open space areas. The removal and monitoring
program shall include annual late winter removal of any rooted plants when soils are saturated
and cutting back of any remaining flowering plants in the spring before seed begins to set in late
April.
e. Provisions for maintenance of landscaping and revegetation of graded slopes shall be specified
as part of the plan, with replacement plantings and seeding provided as necessary to ensure re-
establishment of cover. Tree replacement shall be at ratios consistent with Mitigation Measure
BIO-2d below and meet with the intent of Petaluma Municipal Code Section 20.32.320.
Maintenance and monitoring of mitigation and habitat enhancement plantings in open space
areas shall be provided for a minimum of five years.
f. Vehicles and motorcycles shall not be allowed to travel off designated roadways and limits of
grading to minimize future disturbance to grassland cover and other vegetation, and
unauthorized access to the surrounding undeveloped lands and open space.
29. Mitigation Measure B1O-2b: The Tree Preservation Plans shall be updated and refined to comply with
the requirements of IZO Chapter 17. The Grading Plan and Landscape Plan shall include the
mapped location of tree trunks, including those which will be preserved or removed, show the
recommended tree protection zones, and identify locations of construction-restriction fencing.
30. Mitigation Measure B1O-2c: A Tree Replacement Program shall be prepared as part of the
Landscape and Vegetation Management Plan to provide for replacement of individual native trees
removed by proposed development. The Tree Replacement Program shall provide for replacement
of impacted individual native trees consistent with Petaluma Municipal Code Section 20.32.320 and
Implementing Zoning Ordinance Section 17.065, and shall be accomplished on-site in designated
open space areas. Tree plantings shall be monitored and maintained for a minimum of 5 years by a
qualified biologist or landscape specialist. All water used for temporary irrigation shall be from wells
and/or municipal supplies and not diverted out of Kelly Creek, the stock pond or tributary drainages
to prevent any potential secondary adverse impacts to existing aquatic habitats. Any plantings lost
within this monitoring period shall be replaced at a 1:1 ratio on an annual basis to maintain the
replacement values specified in the Municipal Code and Implementing Ordinance.
Planning Commission Resolution No.2022-15 Page 14
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
31. Mitigation Measure BIO-2d: To avoid creation of informal trails through native grasslands on Helen
Putnam Regional Park adjacent to the project site, the existing fence between the project site and
the regional park to the north of Kelly Creek shall be maintained and strengthened to control
unauthorized entry into the regional park from the terminus of the Kelly Creek multi-use trail. As and
when the regional park trail project is constructed, the fence may be removed.
32. Mitigation Measure BIO-2e: A Native Grassland Avoidance and Replacement Program (Program)
shall be developed by a qualified biologist in consultation with CDFW to address the loss of native
grasslands on the site and provide for adequate replacement. The Program shall define short-term
construction controls and long-term maintenance requirements necessary to ensure grasslands are
successfully reestablished and existing and restored native grasslands remain viable. The
maintenance and management requirements shall include provisions for annual invasive species
removal, and control on the establishment of both native and non-native trees and shrubs that
could eventually shade out the grassland to be protected.The Final Program shall be subject to
review and approval by the City and CDFW. The Program shall contain the following provisions and
performance standards:
a. The proposed limits of grading and enhancement tree plantings shall be modified to avoid
additional areas of the stands of native grassland on the site and a compensatory mitigation
component prepared and implemented to provide a minimum 1:1 replacement ratio for
grasslands lost as a result of the project.
b. Areas retained or restored as native grassland shall be permanently protected as open space
and managed as native grassland by deed restriction or conservation easement.
c. To prevent inadvertent disturbance of native grassland to be preserved, these areas shall be
flagged in the field prior to any vegetation removal or grading for habitat restoration, and
temporary orange construction fencing installed under supervision of the qualified biologist
around all areas to be retained within 50 feet of proposed disturbance.
d. Areas of native grassland within the limits of proposed grading and construction shall be
salvaged and used in revegetation efforts implemented as part of the Program. Salvage
material may include mature seed and intact stem and root material, which shall be stored and
maintained until ready for reinstallation in the late fall/early winter when conditions are optimal
for successful reestablishment.
e. Personnel involved in habitat restoration activities shall be trained by the qualified biologist over
the sensitivity of the native grasslands, purpose of the temporary orange construction fencing,
and that all construction-related disturbance should be restricted outside of the fence.
f. A monitoring program shall be implemented by the qualified biologist to oversee successful
establishment of any native grasslands to be restored, and shall define both short-term and long-
term requirements. Permanent monitoring transects shall be established as part of the program
and vegetation data collected in the spring and summer months when plant identification is
possible. Photo stations shall be established along each monitoring transect, and photographs
taken every year during the required monitoring period. Performance standards, success criteria,
and contingency measures shall be defined as part of the Program. Monitoring transects shall
be established over each location to be vegetated as native grassland, and monitored on an
annual basis. Within a five-year period, native grass shall be successfully established over all
treatment areas and shall comprise a minimum 50 percent of the relative cover. Monitoring shall
be extended where the success criteria are not met, and the minimum 1:1 replacement ratio is
not reached. The Program and its requirements may be modified to require further measures if
monitoring shows that performance standards are not being met.
Planning Commission Resolution No.2022-15 Page 15
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
g. Annual monitoring reports shall be prepared by the qualified biologist and submitted to the
CDFW and Community Development Department of the City of Petaluma by December 31 of
each monitoring year, for a minimum of five years or until the defined success criteria are met.
The annual report shall summarize the results of the monitoring effort, performance standards,
and any required contingency measures, and shall include photographs of the monitoring
transects and program success. Maps shall be included in the monitoring report to show the
location of monitoring transects and photo stations.
33. Mitigation Measure BIO-3: A Final Wetland Replacement and Enhancement Program (WREP) shall
be prepared and implemented to compensate for the loss of jurisdictional waters on the project
site. The Final WREP shall be prepared by a qualified wetland consultant in consultation with and for
review and approval by the City, the RWQCB, the USACE, and the CDFW. The Final WREP shall
clearly identify the total wetlands and other jurisdictional areas affected by the project, shall identify
compensatory mitigation to replace wetland habitat lost as a result of development, and provide
for re-establishment, enhancement, and/or replacement of wetlands. The Final WREP shall include
the following performance standards:
a. Identify the location(s) of mitigation sites and provide for replacement of wetland habitat loss
at a minimum replacement ratio of 2:1. Create or restore wetlands with high functions and
values in accordance with USACE and RWQCB standards. Compensatory mitigation can be
achieved through on- or off-site habitat creation or through the use of an approved mitigation
bank, or a combination thereof.
b. Specify performance criteria, maintenance and long-term management responsibilities,
monitoring requirements, and contingency measures.This shall include expanding the
compensatory mitigation to achieve a replacement ratio of at least 2:1 (or as otherwise
required by regulatory agencies). Monitoring shall be conducted by the project applicant's
consulting wetland specialist for a minimum of five years and continue until the success criteria
are met.
c. Define site grading, preparation and revegetation procedures, an implementation schedule,
and funding sources to ensure long-term management of the Final WREP.
d. The mitigation (habitat restoration or enhancement) effort shall be considered successful when
the performance standards are met. Performance standards would be met when the habitat
has sustained itself for a minimum of two years in the absence of significant maintenance
measures.
Subsequent permitting processes with resource agencies could result in additional mitigation
beyond that required by the City in the CEQA process. Any additional mitigation required by the
agencies (the RWQCB, the USACE, and the CDFW) would be incorporated as conditions of their
permit authorization.
34. Mitigation Measure BIO-4a: An interpretive program shall be developed by a qualified biologist in
cooperation with the project landscape architect which serves to educate park visitors and trail
users of the sensitivity of Kelly Creek and D Street tributary as wildlife movement corridors, and the
importance of remaining outside the southern portion of the site to protect the stock pond and
surrounding uplands to CRLF and other wildlife that are sensitive to human disturbance. The
interpretive program shall be integrated into the final Landscape Plan for the project. Interpretive
elements of the program shall include use of permanent signage at the trail heads, all pedestrian
bridge crossings, and other critical locations. The signage shall explain the sensitivity of the open
space for wildlife and the importance of staying on the improved trails and out of restricted areas.
Dogs, cats, and other pets shall be leashed at all times in the open space areas on the site, and
signage shall be provided at the trail heads at D Street and Windsor Drive explaining this restriction
and need to prevent harassment of wildlife by unleashed pets.
Planning Commission Resolution No.2022-15 Page 16
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
35. Mitigation Measure BIO-4b: The existing plywood barrier fence on the east side of the D Street
concrete box culvert undercrossing shall be removed as part of initial construction activities to
improve opportunities for wildlife movement along the Kelly Creek corridor. Replacement fencing at
this undercrossing shall be prohibited to prevent future obstruction of wildlife movement along Kelly
Creek.
36. Mitigation Measure BIO-4c: Fencing, signage, dense native vegetation, and other deterrents shall
be used as part of the interpretive program to adequately contain livestock, equestrians and other
visitors with their pets from sensitive wildlife areas, including Kelly Creek, the D Street tributary, and
stock pond. Exclusionary fencing used to contain livestock and control access by visitors and their
pets shall be wildlife-friendly in design, such as barbed wire with a smooth bottom wire. Signs shall be
posted along the trails limiting access of equestrian to designated trails at all times.
37. Mitigation Measure BIO-4d: The existing fencing between the western boundary of the project site
and Helen Putnam Regional Park south of Kelly Creek shall be removed where it borders lands to be
dedicated as permanent open space on the project site, and replaced with wildlife-friendly
fencing, such as barbed wire with smooth bottom wire, if fencing is necessary. This would improve
opportunities for wildlife movement between the existing parklands and the future open space
lands on the project site.
a. Exclusionary fencing shall be installed prior to grading or major vegetation clearance where
appropriate to keep CRLF out of construction areas, if required by the USFWS and/or CDFW.The
Final CRLFMP shall identify where such fencing is to be installed and provide procedures for
fence installation, monitoring, and maintenance, if required. The exclusionary fencing be
installed under the direct supervision of a Service-approved biologist and shall be maintained
during the course of construction activities on the site.
b. Sonoma County Regional Parks shall prohibit access by unleashed dogs and require that dogs
be leashed, and that access be limited to designated trails at all times to minimize the potential
for inadvertent take of CRLF.
c. Sonoma County Regional Parks shall post signs along the trails limiting access of equestrian to
designated trails at all times.
d. Sonoma County Regional Parks shall implement measures to minimize the potential for
harassment or take of listed and non-listed species as a result of increased human activity
associated with the proposed trail. This shall include an educational program for future part
visitors, signage at access points into open space and other key locations, and possible use of
permanent exclusionary fencing, if required by the USFWS. Appropriate interpretive signage shall
be provided instructing park users on access rules to prevent inadvertent take of CRLF.
38. Mitigation Measure CUL-1a: Prior to the relocation of the barn structures, a qualified historic
preservation architect shall be selected by the City of Petaluma to review the relocation plans and
verify that the relocation is not affecting the building structures and character defining features. To
ensure the barn structures would retain their eligibility for the local designation, the barn structures
shall be relocated within the same general area and the new location shall be compatible with
their original character and use.
39. Mitigation Measure CUL-1 b: The Applicants shall retain a qualified preservation architect to oversee
the relocation process and ensure that all the relocation activities are implemented in compliance
with the relocation plans reviewed under Mitigation Measure CUL-1 a.
Planning Commission Resolution No.2022-15 Page 17
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
40. Mitigation Measure CUL-2a: Prior to excavation and construction on the proposed project site, the
prime construction contractor and any subcontractor(s) shall be informed by a qualified
archaeologist retained by the project Applicants, on the legal and/or regulatory implications of
knowingly destroying cultural resources or removing historic or prehistoric artifacts, human remains,
and other cultural materials from the project site as outlined in Mitigation Measure CUL-2b below.
41. Mitigation Measure CUL-2b: Prior to commencing any demolition, excavation or other ground-
disturbing activities, the project Applicants shall retain a qualified archaeologist to monitor
construction activity. The City shall approve the selected project archaeologist prior to issuance of
the grading and/or demolition permit.The selected project archaeologist shall be present at the
preconstruction meeting to discuss what protocols should be followed with respect to the potential
discovery of prehistoric or historic artifacts of possible significance. The selected project
archaeologist shall have the authority to perform full time or spot check monitoring of subsurface
construction and watch for and evaluate artifacts or resources that may be uncovered.
The selected project archaeologist shall have the authority to halt excavation and construction
activities in the immediate vicinity (distance to be determined by the project archaeologist) of a
find if significant or potentially significant cultural resources are exposed and could be adversely
affected by construction operations. Construction activities could continue in other areas of the
project site where no cultural resources have been identified.
42. Mitigation Measure CUL-2c: Should archaeological resources be encountered during ground-
disturbing activities (i.e., grading and excavation), the project archaeologist shall initiate sampling,
identification, and evaluation of the resources. If the archaeological resources are found to be
significant, the archaeologist shall take appropriate actions in conjunction with the City for
preservation and/or data recovery, including recordation with the California Historic Resources
Information System (CHRIS) and professional museum curation as appropriate. Following the
completion of evaluation and data recovery, the archaeologist shall prepare a professional report
detailing the results of the find and submit it to the City of Petaluma Community Development
Department and to CHRIS along with a DPR form to ensure that resource inventories are accurately
updated.
43. Mitigation Measure CUL-3: Procedures to be implemented following the discovery of human
remains have been mandated by Health and Safety Code Section 7050.5, Public Resources Code
Section 5097.98 and the California Code of Regulations Section 15064.5(e) (CEQA). According to
the provisions in CEQA, if human remains are discovered at the project site during construction, work
at the specific construction area at which the remains have been uncovered shall be suspended,
and the City of Petaluma and County of Sonoma coroner shall be immediately notified. If the
remains are determined by the County coroner to be Native American, the Native American
Heritage Commission (NAHC) shall be notified within 24 hours, who will, in turn, notify the person the
NAHC identifies as the most likely descendent ("MLD") of any human remains. The guidelines of the
NAHC shall be adhered to in the treatment and subsequent disposition of the remains. Further
actions shall be determined, in part, by the desires of the MLD. The MLD has 48 hours to make
recommendations regarding the disposition of the remains following notification from the NAHC of
the discovery. If the MLD does not make recommendations within 48 hours, the owner shall, with
appropriate dignity, re-inter the remains in an area of the property secure from further disturbance.
Alternatively, if the owner does not accept the MLD's recommendations, the owner or the
descendent may request mediation by the NAHC.
44. Mitigation Measure GEO-1 a: The project Applicants shall submit for City's approval a
preconstruction design-level geotechnical report for the Davidon (28-Lot) Residential Project
component and the Putnam Park Extension Project component. The report shall include all
Planning Commission Resolution No.2022-15 Page 18

applicable geologic report standards, reconnaissance and subsurface exploration data, laboratory
test results, and conclusions and recommendations, including, but not limited to, those pertaining to:
1) site preparation, excavation, fill placement and compaction, temporary and permanent cut and
fill slope inclinations (including whether slopes steeper than 3:1 can be used at the site), slope
stability, slope erosion mitigation, and landslide movement mitigation; 2) surface and subsurface
drainage systems, including drainage associated with grading for landslide movement mitigation
and new cut and fill slopes; 3) foundations and floors for planned residential structures; 4)
foundations for planned site improvements, including, but not limited to restrooms, barn, pedestrian
bridges, and other structures; 5) settlement and swell estimates for planned residential structures and
site improvements, including those bearing of engineered fill; 6) foundations, back-drains, and
lateral earth pressures for site retaining walls; 7) seismic design parameters for the planned
residential structures, site improvements, and site retaining walls; 8) pavement design for driveways,
parking lots, pathways and trails, where applicable; 9) utility trench backfill, including check dams
and trench drainage, if appropriate; 10) geologic/geotechnical construction monitoring, testing,
and certification requirements; and 1 1) loop trail construction and long-term maintenance
requirements, including criteria for inspecting and maintaining pedestrian bridges, culverts, and
pathway surfaces, as appropriate.
The geotechnical report shall include measures, as necessary, to reduce the potential for static and
earthquake-induced slope movements that may adversely impact the Davidon (28-Lot) Residential
Project component and the Putnam Park Extension Project component including areas currently
underlain by mapped landslides. Engineering analyses shall estimate the factors of safety against
slope movements within the planned development area and estimates of the magnitude and
location of earthquake-induced slope deformation.
45. Mitigation Measure GEO-1 b: As determined by the City Engineer and/or Chief Building Official, all
recommendations outlined in the preconstruction design-level geotechnical report for the Davidon
(28-Lot) Residential Project component and the Putnam Park Extension Project component, as
described under Mitigation Measure GEO-1 a, are herein incorporated by reference and shall be
adhered to in order to ensure that appropriate measures are incorporated into the design and
construction of the project. Nothing in this mitigation measure shall preclude the City Engineer
and/or Chief Building Official from requiring additional information be provided to determine
compliance with applicable standards. The project geotechnical engineer shall review the project
plans and specifications and submit a letter certifying to the City that the project plans and
specifications have been prepared in accordance with the geotechnical recommendations for the
project. The project geotechnical engineer or personnel under their direct supervision shall inspect
the construction of geotechnical and/or geologic aspects of the project and shall submit a letter
certifying to the City that prior to issuance of a certificate of occupancy, the geotechnical and
geologic aspects of the project plans and specifications have been appropriately constructed at
the site and are acceptable to the project geotechnical engineer.
46. Mitigation Measure GEO-2a: The preconstruction design level geotechnical report, identified in
Mitigation Measure GEO-1, shall include specific recommendations to mitigate surface erosion. The
project geotechnical engineer or personnel under their direct supervision shall inspect the
construction of geotechnical and/or geologic aspects of fill placement and compaction and
surface drainage systems of cut and fill slopes to ensure that the geotechnical recommendations
associated with mitigating surface soil erosion are properly implemented during construction. At a
minimum, 1) slope inclinations shall be no steeper than 3:1 (horizontal to vertical), unless the project
engineering geologist specifically indicates that a steeper slope would perform satisfactorily over
the long term, 2) fill slope requirements shall include a process of overbuilding the fill on the slope
and shaving it back to expose a well compacted fill surface that is less susceptible to surface
erosion, and 3) the project civil engineer shall check the final grading of the site and the elevations
Planning Commission Resolution No.2022-15 Page 19
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
of the surface drainage systems to confirm that the grading contractor graded the site and
constructed surface improvement in accordance with the approved grading plans.
47. Mitigation Measure GEO-2b: The project geotechnical engineer shall review the geotechnical
aspects of the SWPPP and, where applicable, shall provide comments to the Qualified SWPPP
Developer (QSD) to ensure that the geotechnical recommendations associated with mitigating
surface soil erosion through BMPs and a long-term monitoring and maintenance program of the
planned cut and fill slopes are properly incorporated into the SWPPP and/or a project specific
operations and maintenance plan. As a minimum, the geotechnical aspects of the SWPPP shall
include a requirement to check the condition of the slope at the beginning of the first rainy season
after the completion of grading and periodic inspections until surface vegetation has been fully
established on the exposed slopes.
48. Mitigation Measure GEO-3a: Where landslide mitigation is required under Mitigation Measure GEO-
1 a, the project geotechnical engineer or personnel under their direct supervision shall inspect the
excavation and grading associated with the landslide removal and/or stabilization work to ensure
that the geotechnical recommendations associated with mitigating landslide hazards are properly
implemented during construction.
The project geotechnical engineer shall evaluate Landslides B, G, H, L, N. O, and R, which have a
potential to adversely impact the foundations of footbridges and/or the loop trail pavement. As a
minimum, the project geotechnical engineer shall establish an inspection and maintenance
program to ensure that any damage to the planned footbridge foundations and loop trail
improvements due to landslide movements are identified and repaired.
49. Mitigation Measure GEO-3b: The project geotechnical engineer, project engineering geologist, or
personnel under their direct supervision shall inspect all cut slopes focusing on evidence of potential
instability. If areas of adverse bedrock structure are encountered, then the project geotechnical
engineer and/or project engineering geologist shall develop remedial measures for these slopes
and the grading contractor shall implement the remedial activity, under the direction and
supervision of project geotechnical engineer and/or engineering geologist, and acceptable by the
City engineer.
50. Mitigation Measure GEO-4a: A preconstruction geotechnical report shall be prepared for the
Davidon (28-Lot) Residential Project component and the Putnam Park Extension Project component,
as previously discussed in Mitigation Measure GEO-1 a. Specific to site geology, bedrock shear,
settlement, and expansive soil, the project geotechnical engineer shall confirm that the conclusions
and all applicable recommendations previously presented in the 2015 design-level geotechnical
report are still applicable for the design and construction of the Davidon (28-Lot) Residential Project
component and the Putnam Park Extension Project component.
51. Mitigation Measure GEO-4b: As a minimum, cut lots that have subgrades exposing bedrock shall be
over-excavated and recompacted to a minimum depth of three feet, and backfilled as described
below, unless the project geotechnical engineer provides project specific alternative
recommendations to mitigate the potential for differential settlement associated with variable
settlement and swell behavior between bedrock and compacted engineered fill. The exposed
surface shall be scarified to a depth of about 12 inches, moisture-conditioned to not less than three
percent over optimum moisture content and compacted to at least 90 percent relative
compaction.
Excavation deeper than the above recommendations may be required to expose competent
material under conditions where soft or saturated soil is encountered. The excavation depth will be

determined in the field as part of the geotechnical analysis required under Mitigation Measure GEO-
1 a.
Project site grades shall be designed to slope away from the proposed structures, and water from
roof drains shall be directed to suitable outlets. Fill slopes comprised of low to moderately expansive
soil shall be evaluated for stability (see Mitigation Measures GEO-1 a and GEO-3a). Additional
mitigations to reduce the impact of expansive soils on the proposed residences shall include:
a. Moisture conditioning and re-compacting low to moderately expansive soil.
b. Placing non-expansive fill beneath the homes and rigid surface improvements.
c. Designing foundations to resist or tolerate differential movement of moderately expansive soil.
52. Mitigation Measure GEO-6a: The project Applicants shall identify a qualified paleontologist prior to
any demolition, excavation, or construction. The City shall approve the selected project
paleontologist prior to issuance of the demolition permit. The paleontologist shall attend the pre-
grading meeting to inform the contractor(s) how to recognize paleontological resources in the soil
during grading activities. The prime construction contractor and any subcontractor(s) shall be
informed on the legal and/or regulatory implications of knowingly destroying paleontological
resources or removing paleontological resources from the project site.
53. Mitigation Measure GEO-6b: If paleontological resources are encountered during the course of site
development activities, work in that area shall be halted and the selected project paleontologist, as
outlined in Mitigation Measure GEO-6a above, shall be notified of the find to determine the
significance of the find and to recommend appropriate mitigation measures. Recommendations
shall be presented for City approval in a Treatment and Recovery Plan. The selected project
paleontologist shall have the authority to temporarily divert or redirect grading to allow time to
evaluate any exposed fossil material.
54. Mitigation Measure GEO-6c: If the selected project paleontologist determines that the resource is
significant, then any scientifically significant specimens shall be properly collected by the project
paleontologist. During collecting activities, contextual stratigraphic data shall also be collected. The
data will include lithologic descriptions, photographs, measured stratigraphic sections, and field
notes.
Scientifically significant specimens shall be prepared to the point of identification (not exhibition),
stabilized, identified, and offered for curation to a suitable repository that has a retrievable storage
system, such as the University of California, Berkeley, Museum of Paleontology.
The selected project paleontologist shall prepare a final report at the end of the earth-moving
activities. The report shall include an itemized inventory of recovered fossils and appropriate
stratigraphic and locality data. The project paleontologist shall send one copy of the report to the
City of Petaluma Community Development Department; another copy should accompany any
fossils, along with field logs and photographs, to the designated repository.
55. Mitigation Measure HYD-1 a: Prior to issuance of grading permits for the proposed project, the City of
Petaluma shall verify that the Applicants have prepared a SWPPP in accordance with the
requirements of the statewide Construction General Permit. The SWPPP shall be designed to address
the following objectives: (1) all pollutants and their sources, including sources of sediment
associated with construction, construction site erosion, and all other activities associated with
construction activity are controlled; (2) where not otherwise required to be under a Regional Water
Quality Control Board permit, all non-stormwater discharges are identified and either eliminated,
controlled, or treated; (3) site BMPs are effective and result in the reduction or elimination of
Planning Commission Resolution No.2022-15 Page 21
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
pollutants in stormwater discharges and authorized non-stormwater discharges from construction
activity; and (4) stabilization BMPs are installed to reduce or eliminate pollutants after construction is
completed. The SWPPP shall be prepared by a qualified SWPPP developer. The SWPPP shall include
the minimum BMPs required for the identified Risk Level. BMP implementation shall be consistent with
the BMP requirements in the most recent version of the California Stormwater Quality Association
Stormwater Best Management Handbook-Construction or the Caltrans Stormwater Quality
Handbook Construction Site BMPs Manual.
56. Mitigation Measure HYD-lb: In areas within 50 feet of sensitive habitat areas, construction activities
should be planned to avoid disturbance of riparian vegetation, including trees and their root
systems. The SWPPP shall specifically address special considerations for controlling sediment and
other pollutants within these areas, through additional erosion control measures (such as berms and
temporary retention/settling basins that divert runoff away from the creek banks, limiting the use of
heavy construction vehicles within the riparian zone, or conserving and replacing topsoil during
grading near the riparian zone to speed up the re-establishment of stabilizing vegetation), to limit
grading near riparian areas to occur only during the dry-season. Erosion control measures shall also
include staged grading to reduce the area of exposed soil at any one period of time, and/or other
measures specifically tailored to riparian and sensitive areas.
57. Mitigation Measure HYD-lc: The project shall implement appropriate post-construction stormwater
treatment measures to reduce water quality and hydromodification impacts to downstream
reaches, as required by the current post construction controls requirements of the Small MS4
General Permit. Upon completion of the final project design, the Applicants shall provide
documentation to the City of stormwater management measures that show compliance with the
Small MS4 General Permit.The report shall delineate individual drainage management areas (DMAs)
within the project site and provide analysis to show compliance with the volumetric or flow-based
treatment criteria as described in the Small MS4 General Permit and outlined in the 2019 BASMAA
(2019) guidance document. The report shall also include design calculations that show post-project
runoff for the 2-year, 24-hour storm event does not exceed pre-project flow for each DMA, and that
each DMA has appropriate stormwater quality treatment based on flow- or volumetric-based
calculation, as outlined in the Small MS4 General Permit and in compliance with the 2019 BASMAA
guidance document (2019). The final documentation shall be submitted to the City for approval
before the beginning of grading.
58. Mitigation Measure HYD-1d: The proposed multi-use trails shall be designed to direct stormwater
runoff away from Kelly Creek and D-Street tributary and/or to vegetated pervious areas not
susceptible to erosion. The path shall be designed to limit the amount of runoff concentrated from
any one portion of the path in order to prevent gullying. In areas close to Kelly Creek or otherwise
not suitable for distributed discharge of runoff, stormwater treatment measures such as swales shall
be implemented to protect the creek.
59. Mitigation Measure HYD-3: Stormwater outfalls to Kelly Creek and the D Street tributary shall be
designed to reduce the potential to cause bank instability. Outfall locations near (or especially
across from) existing or potential bank instabilities shall be avoided so that outflows do not
exacerbate erosion. Appropriate energy dissipation, such as boulder aprons, biostabilization, or
directing outfalls in a downstream rather than cross-channel direction, shall be incorporated to
reduce the potential to cause erosion
60. Mitigation Measure HYD-4a: Prior to final map approval, the Applicants shall submit final detention
design that shows that appropriate controls have been included to ensure that the post-project 10-
and 100-year peak flows will not exceed pre-project peaks. Hydrologic analyses and final detention
Planning Commission Resolution No.2022-15 Page 22
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
designs shall be consistent with the standards outlined in Sonoma Water's Flood Management
Design Manual, adopted May 19, 2020. Total detention volume may be less than the volume
projected in the preliminary hydrologic analysis if final analysis shows appropriate compliance
through integrated LID/water quality treatment/detention features. Final hydrologic analysis and
detention sizing shall include potential increases in peak flow due to all new impervious surfaces
associated with the proposed project, including the parking areas.
61. Mitigation Measure HYD-4b: The project Applicants shall prepare and execute, in coordination with
the City Engineer or other privately funded and operated maintenance mechanism which ensures
that maintenance of all detention facilities will be provided as necessary to continuously provide the
required volume storage in a 10-year storm and in a 100-year storm, throughout the life of the
project, and shall include a financing mechanism acceptable to the City Engineer to ensure that
the required maintenance will be performed.
62. Mitigation Measure HYD-4c: The project Applicants shall design, in coordination with the City
Engineer, on-site detention facilities sufficient to detain on-site and release runoff from storm events
such that any runoff temporarily detained on-site is released either before or after the expected
peak flood flow of the Petaluma River and that any release of runoff temporarily detained on-site
does not contribute to an increase in peak flood periods on the Petaluma River. Prior to final map
approval, the project Applicants' final stormwater detention design calculations shall be subject to
review by the City's stormwater consultant and City Engineer.The project Applicants shall be
responsible for funding all costs and providing the required technical information to the City.
63. Mitigation Measure HYD-6: Pedestrian bridges across Kelly Creek shall be designed to fully span the
channel in order to reduce the potential to impede streamflow. If full-span lengths are not feasible,
bridge supports shall be designed to maximize the natural channel cross-section area in order
reduce the potential obstruction to in-stream flow.
64. Mitigation Measure NOISE-1: The proposed project shall implement the following control measures
during construction.
a. Noise-generating construction activities shall be limited to daytime, weekday hours (7 AM to 6
PM) and 9 AM to 5 PM on weekends and holidays. When construction is occurring within 100 feet
of existing residences, then construction shall occur between 9 AM and 5 PM and shall be
prohibited on Sundays and Holidays.
b. High noise-producing activities, such as excavation and grading and construction finishing, shall
be scheduled between the hours of 8 AM and 5 PM to minimize disruption on sensitive uses.
c. All stationary noise generating equipment that generates noise levels in excess of 65 dBA Leq
shall be located as far as possible from sensitive receptors. If re-locating stationary equipment is
not feasible, the equipment shall be shielded from noise sensitive receptors by using temporary
walls, sound curtains, or other similar devices to reduce noise levels at nearby sensitive receptors
to less than 65 dBA Leq.
d. The construction contractor shall implement feasible noise controls to minimize equipment noise
impacts on nearby sensitive receptors. Feasible noise controls include improved mufflers, use of
intake silencers, ducts, engine enclosures, and acoustically-attenuating shields or shrouds.
e. Equipment used for project construction shall be hydraulically or electrically powered impact
tools (e.g.,jack hammers) wherever possible to avoid noise associated with compressed air
exhaust from pneumatically-powered tools. Where use of pneumatically-powered tools is
unavoidable, an exhaust muffler on the compressed air exhaust shall be used. A muffler could
Planning Commission Resolution No.2022-15 Page 23
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
lower noise levels from the exhaust by up to about 10 dBA. External jackets on the tools
themselves shall be used where feasible; this could achieve a reduction of five dBA. Quieter
procedures shall be used (such as drilling rather than impact equipment) wherever feasible.
f. The construction contractor shall implement appropriate additional noise reduction measures
that include shutting off idling equipment after 5 minutes (as feasible) and notifying adjacent
residences (at least one time) in advance of construction work.
g. The construction contractor shall not stage equipment within 200 feet of the existing residences
adjacent to the project site.
h. The contractor shall minimize use of vehicle backup alarms. A common approach to minimizing
the use of backup alarms is to design the construction site with a circular flow pattern that
minimizes backing up of trucks and other heavy equipment. Another approach to reducing the
intrusion of backup alarms is to require all equipment on the site to be equipped with ambient
sensitive alarms. With this type of alarm, the alarm sound is automatically adjusted based on the
ambient noise.
i. Construction worker's radios shall be controlled so as to be inaudible beyond the limits of the
project site boundaries.
j. Heavy equipment, such as paving and grading equipment, shall be stored on-site whenever
possible to minimize the need for extra heavy truck trips on local streets.
k. Two weeks prior to the commencement of construction, notification in writing must be provided
to residents within 300 feet of the project site, disclosing the construction schedule, including the
various types of activities that would be occurring throughout the duration of the construction
period.
I. The construction contractor shall designate a city-approved "disturbance coordinator"who shall
be responsible for responding to any local complaints about construction noise. The disturbance
coordinator shall determine the cause of the noise complaint (e.g., starting too early, bad
muffler, etc.) and shall require that reasonable measures warranted to correct the problem be
implemented. The construction contractor shall conspicuously post a telephone number for the
disturbance coordinator at the construction site and include it in the notice sent to neighbors
regarding the construction schedule.
65. Mitigation Measure NOISE-2a: Heavy construction equipment shall be prohibited from operating
within 100 feet of an existing residence between the hours of 5:00 PM and 9:00 AM and on holidays.
66. Mitigation Measure NOISE-2b: Operation of heavy equipment shall be prohibited within 20 feet of
the barn complex. Temporary reinforcements/stabilization measures shall be installed at the barn
structures, as needed, to minimize vibration damage.
67. Mitigation Measure TRANS-5: A construction management plan shall be prepared for review and
approval by the City of Petaluma Public Works Department. The plan shall include at least the
following items:
a) Development of a construction truck route that would appear on all construction plans to limit
truck and auto traffic on nearby streets.
b) Comprehensive traffic control measures, including scheduling of major truck trips and deliveries
to avoid peak traffic hours, detour signs if required, lane closure procedures if required, sidewalk
closure procedures if required, cones for drivers, and designated construction access routes.
Planning Commission Resolution No.2022-15 Page 24
DocuSign Envelope ID: FA7C658B-EC63-4EAD-B9FC-4A42C70F1D1F
c) Evaluation of the need to provide flaggers or temporary traffic control at key intersections along
the truck route(s).
d) Notification procedures for adjacent property owners and public safety personnel regarding
schedules when major deliveries, detours, and lane closures would occur.
e) Location of construction staging areas for materials, equipment, and vehicles if there is
insufficient staging area within the work zone of the proposed project.
f) Identification of truck routes for movement of construction vehicles that would minimize impacts
on vehicular and pedestrian traffic, circulation and safety; provision for monitoring surface
streets used for truck movement so that any damage and debris attributable to the proposed
project's construction trucks can be identified and corrected by the proposed project
applicant.
g) A process for responding to and tracking complaints pertaining to construction activity,
including identification of an on-site complaint manager.
h) Documentation of road pavement conditions for all routes that would be used by construction
vehicles both before and after proposed project construction. Roads found to have been
damaged by construction vehicles shall be repaired to the level at which they existed prior to
construction of the proposed project.
68. Mitigation Measure UTL-3a: Prior to issuance of building permits, the project shall be required to
upsize the D Street sewer between Grossland Way to the manhole west of 1 Oth Street, subject to the
review and approval by the City Public Works and Utilities Department.
69. Mitigation Measure UTL-3b: Mitigation Measure AIR-2, Mitigation Measures CUL-2a through 2c,
Mitigation Measure CUL-3, and Mitigation Measure NOISE-1 and NOISE-2a shall be implemented in
conjunction with the sewer main upgrade project.
