WHEREAS,also at the February 27,2023,public hearing the City Council introduced Ordinances Nos. 2839
N.C.S. and 2840 N.C.S. approving the Zoning Map Amendment and Zoning Text Amendment to create the Scott
Ranch PUD.
NOW THEREFORE, BE IT RESOLVED by the Petaluma City Council 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) containing all the
requirements of CEQA Guidelines Section 1532, inclusive of the RDEIR, references, appendices, and all
attachments thereto.
3. On February 27,2023,the City Council approved Resolution No.2023-023 N.C.S. certifying the EIR,making
findings of fact to adopt a statement of overriding considerations, and adopting a mitigation monitoring and
reporting program for the Scott Ranch Project.
4. Also on February 27, 2023, the City Council introduced Ordinance Nos. 2839 N.C.S. and 2840 N.C.S.
approving a Zoning Map Amendment and Zoning Text Amendment to establish the Scott Ranch PUD.
5. The City Council approval of the Vesting Tentative Subdivision Map for the Scott Ranch Project is based on
the findings made below and subject to the conditions of approval attached as Exhibit A 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 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.
Resolution No. 2023-025 N.C.S. Page 4
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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 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, hot 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 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 August 9,2022 Planning Commission staff report and February 27,2023 City Council
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 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 11 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.

DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
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.

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
F-1- 5
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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
fencingibarriers 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.
F-1- 6
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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 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
27. Mitigation Measure BIO-lc: 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
F-1- 7
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
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 13I0-1d.
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.
28. Mitigation Measure BI0-1d: 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.

29. Mitigation Measure BIO-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), 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 (Wex 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 13I0-2d 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-1- 9
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
30. Mitigation Measure BI0-2b: 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.
31. Mitigation Measure BI0-2c: 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.
32. Mitigation Measure BI0-2d: 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.
33. Mitigation Measure BI0-2e: 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.
F-1- 10
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
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.
34. 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,
F-1- 11
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
35. Mitigation Measure BI04a: 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.
36. Mitigation Measure BI04b: 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.
F-1- 12
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
37. Mitigation Measure BI04c: 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.
38. Mitigation Measure BI04d: 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 CRUMP 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.
39. Mitigation Measure CUL-la: 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.
40. Mitigation Measure CUL-lb: 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-la.
F-1- 13
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
41. 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.
42. 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.
43. 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.
44. 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
F-1- 14
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
45. Mitigation Measure GEO-la: 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
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 11) 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.
46. Mitigation Measure GEO-lb: 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-la, 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
F-1- 15
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
47. 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 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.
48. 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.
49. Mitigation Measure GEO-3a: Where landslide mitigation is required under Mitigation
Measure GEO-la, 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.
50. 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,
F-1- 16
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
under the direction and supervision of project geotechnical engineer and/or engineering
geologist, and acceptable by the City engineer.
51. 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-la. 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.
52. 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-la.
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-
la 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.
53. 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.
F-1- 17
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
54. 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.
55. 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.
56. Mitigation Measure HYD-la: 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 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.
57. 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
F-1- 18
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
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.
58. 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.
59. 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.
60. 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
61. 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 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.
F-1- 19
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
62. 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.
63. 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.
64. 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.
65. 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-
F-1- 20
DocuSign Envelope ID:039194B4-AA25-4B6F-A8F7-75E043FBBE7C
powered tools is unavoidable, an exhaust muffler on the compressed air exhaust shall be
used. A muffler could 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.
1. 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.
66. 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.
67. 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.
68. 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:
F-1- 21
