Exhibit A
Water Recycling Expansion Program EIR Addendum
Introduction
In November 2008 the City certified the Water Recycling Expansion Program EIR (State Clearinghouse
#2007052146) and approved the Program. The EIR evaluated "near- term" improvements at a project
level and the remainder of the improvements and the use of recycled water at a program level of detail.
The near -term improvements included a storage tank and conveyance pipelines that were to be
implemented immediately after certification of the EIR and for which enough detail was known to allow a
project -level review. The improvements evaluated at a program level of detail included use of recycled
water, new pipelines, a small open reservoir, new and upgraded pump stations, and associated facilities.
The program level improvements were to be implemented over a longer period of time, as the demand for
recycled water increased, through 2025.
The City is proposing minor revisions to the overall Program, to expand the recycled water service area
boundary and update a project measure.
Proposed Revisions
This Addendum tiers from the Water Recycling Expansion Program (WREP) EIR and analyzes the
following proposed revisions to the Program:
• Extend the Recycled Water Service Area Boundary along the southeast edge (refer to attached
Revised Figure 2 -2).
• Revise project design measure PD -16, Implement BMPs for Runoff, Erosion, and Agricultural
Chemical Use, to reflect the City's Rules and Regulations for Recycled Water Customers
regarding the use of recycled water.
The City has been approached by several agricultural property owners located southeast of the City
desirous of receiving recycled water for irrigation. Some of the properties are located outside of the
Recycled Water Service Area Boundary, but would support the objectives of the Program to reduce
wastewater discharges and provide additional recycled water for agricultural irrigation. Therefore, the City
proposes to amend the Recycled Water Service Area Boundary, as defined in Figure 2 -2 Concept Plan of
the WREP EIR, to extend it approximately 0.5 mile to the southeast of the existing boundary. The
proposed new boundary for the service area is shown on the attached Revised Figure 2 -2 Concept Plan.
The new properties that would be included within the revised boundary are similar to those currently
within the boundary in that geographic location. The properties are rural, many of which are utilized in
some type of farming activity. Activities that could occur within the revised Service Area Boundary would
remain the same as described in Chapter 2 Project Description of the WREP EIR: use of recycled water,
installation of pipelines and associated appurtenances, and construction staging areas. Inclusion of the
new service area would not require additional length of pipeline beyond that identified and analyzed in the
WREP EIR. The Project Description anticipated approximately 28 miles of pipeline would be installed with
full implementation of the Program; this change to the Service Area Boundary is not anticipated to
increase the overall length of pipe to be installed.
After certification of the WREP EIR in 2008, the City adopted the Rules and Regulations for Recycled
Water Customers (Rules and Regulations) regarding the use of recycled water. Runoff, irrigation
practices, and water waste are now controlled in the Rules and Regulations, resulting in portions of PD-
16 being redundant. In addition, the State program regulating the public health aspects of recycled water
has moved to a different agency. Therefore, the City is proposing revisions to project design measure PD-
16 to clarify the regulatory agency and eliminate redundancies that could be confusing to recycled water
users. The revisions proposed below do not reduce the effectiveness of the mitigation measure; they
merely refer the reader to the City's more specific Rules and Regulations where the same restrictions on
runoff, irrigation practices, and water waste are prescribed in more detail. The proposed changes to PD-
16 are as follows:
Resolution No. 2015 -187 N.C.S. Page 4
Water Recycling Expansion Program EIR Addendum
PD -16 Implement BMPs for Controlling Runoff, Erosion, Agricultural Chemical Use, and
Water Waste
As a purveyor of recycled water, the City of Petaluma is required to ensure that all of the city's
recycled water users are aware of their responsibilities regarding the proper use of recycled water. To
ensure that users are informed of the proper use of recycled water, the City provides each recycled water
user with a copy of "Guidelines for Reeyo °a sxr., +or Users "Rules and Regulations for Recycled Water
Customers ". These guidelines rules are consistent with those promulgated by the Galifomia e+„ +o
Depai.«meiA of Publi . Health (r>1pu) State Water Resources Control Board, Division of Drinking Water
to protect the health of the public and the employees of recycled water users.
The g u =ye&—rules for developing BMPs for- efficient irFigation controlling runoff are located in the
"open ael —C—on4rol" seetie of� "Guidelines - or Ree�elea `: ater ?Teere "Rules and Regulations
for Recycled Water Customers ". See the City of Petaluma, Recycled Water System, Notice of Intent
(NOI) and the Water Reuse Program Technical Report and Engineering Report for the Production,
Distribution, and Use of Recycled Water (City of Petaluma August 2005).
The City shall meet the requirements of General Water Reuse Order 96 -011 authorizing municipal
wastewater reuse by producers, distributors, and users of non - potable recycled wastewater and follow
all provisions of the NOL The City shall implement BMPs to prevent runoff, control erosion and
infiltration, reduce water waste, and reduce impacts of agricultural chemical application on properties
receiving recycled water for irrigation. The following measures, or alternative measures of equivalent
effectiveness to those listed in Order No. 96 -011 (Refer to Appendix C of the Draft EI -this deouffie ),
shall be implemented, depending upon their applicability to site - specific conditions:

Use of an Addendum
The City has determined that the appropriate CEQA document for the proposed revisions to the WREP is
an Addendum to the Water Recycling Expansion Program EIR in accordance with CEQA Guidelines
Section 15164(a) which states that a lead agency shall prepare an addendum to a previously certified EIR
if some changes or additions are necessary, but none of the conditions described in CEQA Guidelines
Section 15162 calling for the preparation of a subsequent EIR has occurred.
Under CEQA Guidelines Section 15162, when an EIR has been certified for a project, no subsequent EIR
shall be prepared for that project unless the lead agency determines, on the basis of substantial evidence
in the light of the whole record, one or more of the following:
(1) Substantial changes are proposed in the project which will require major revisions of the previous EIR or
negative declaration due to the involvement of new significant environmental effects or a substantial increase in
the severity of previously identified significant effects;
Resolution No. 2015 -187 N.C.S. Page 7
Water Recycling Expansion Program EIR Addendum
(2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will
require major revisions of the previous EIR or Negative Declaration due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously identified significant effects; or
(3) New information of substantial importance, which was not known and could not have been known with the
exercise of reasonable diligence at the time the previous EIR was certified as complete or the Negative
Declaration was adopted, shows any of the following:
(A) The project will have one or more significant effects not discussed in the previous EIR or negative
declaration;
(B) Significant effects previously examined will be substantially more severe than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and
would substantially reduce one or more significant effects of the project, but the project proponents decline
to adopt the mitigation measure or alternative; or
(D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous
EIR would substantially reduce one or more significant effects on the environment, but the project
proponents decline to adopt the mitigation measure or alternative.
The proposed revisions would not substantially change the WREP and are consistent with the WREP
Objectives. In addition, the proposed minor revisions would not result in a new significant impact or a
substantially more severe significant effect than identified in the Water Recycling Expansion Program
EIR. The environmental analysis in support of this conclusion is provided below.
Environmental Analysis
As noted above, the new properties that would be included within the revised Service Area Boundary are
similar to those currently within the boundary in that geographic location: rural, with many actively
involved in some type of farming activity. Vegetation, soil types, and slopes also are similar. Program
activities that could occur within the revised Service Area Boundary would be the same as described and
analyzed in the WREP EIR, including application of recycled water, installation of pipelines, and
construction staging. In review of the new properties in the context of the 12 environmental disciplines
analyzed in the WREP EIR, no new impacts were identified and all mitigation measures would still be
applicable. The following is a summary of the key findings.
• The additional property within the revised service area boundary would not be located within
areas classified as MRZ -2 for mineral resources (California Geological Survey, Department of
Conservation, Special Report 205 2013). Therefore, the analysis and impacts relative to mineral
resources in the WREP EIR are adequate for the revised service area.
• No new potential for habitat of special- status species or vegetation communities has been
identified within the revised Service Area Boundary that was not already identified within the
existing service area boundary (CDFW CNDDB 2015). Therefore, the analysis, impacts, and
mitigation measures relative to biological resources in the WREP EIR are adequate for the
revised service area.
Unknown cultural resources could occur within the additional properties. However, the WREP's
Mitigation Measure CR -1 b outlines a four -step process to identify and avoid or minimize impacts
to cultural resources. Mitigation Measure CRA b would be implemented with each individual
subsequent action that was approved under the WREP. Therefore, the analysis, impacts, and
mitigation measures relative to cultural resources in the WREP EIR are adequate for the revised
service area.
Changed Circumstances, New Information
No changes in circumstances, such as new regulations or new reasonably foreseeable relevant
cumulative projects, and no new information has been identified such that the evaluation of environmental
Resolution No. 2015 -187 N.C.S. Page 8
Water Recycling Expansion Program EIR Addendum
impacts of the additional service area would be different than identified in the WREP EIR. As noted
above, the City adopted Rules and Regulations for Recycled Water Customers regarding the use of
recycled water. However, this was done in accordance with the mitigation plan to reduce impacts of the
WREP. It is not a new regulation that would change the analysis or result in new impacts not previously
identified, from implementation of the WREP.

PETALUMA WATER RECYCLING EXPANSION PROGRAM
MITIGATION MONITORING PROGRAM
INTRODUCTION
This Chapter presents the Mitigation and Monitoring Program for the Petaluma Water Recycling
Expansion Program (WREP). The mitigation measures listed herein are required by law or regulation, are
adopted by the City as part of the Project, or are recommended by the environmental team.
The project measures or mitigation measures listed below have been identified in Chapter 4
Environmental Analysis, as feasible and effective in mitigating Project- related environmental impacts.
The effectiveness of each measure is identified in this Chapter and discussed in detail in Chapter 4.
Legal Basis
The legal basis for the development and implementation of a Mitigation and Monitoring Program lies
within the California Environmental Quality Act (CEQA), Sections 21002 and 21002.1:
Public agencies are not to approve projects as proposed if there are feasible alternatives or
feasible mitigation measures available which would substantially lessen the significant
environmental effects of such projects; and
• Each public agency shall mitigate or avoid the significant effects on the environment of projects
that it carries out or approves whenever it is feasible to do so.
CEQA Section 21081.6 further requires that: the public agency shall adopt a reporting or monitoring
program for the changes made to the project or conditions of project approval, adopted in order to
mitigate or avoid significant effects on the environment. The reporting or monitoring program shall be
designed to ensure compliance during project implementation. The monitoring program must be adopted
when a public agency makes its findings under CEQA so that the program can be made a condition of
project approval in order to mitigate significant effects on the environment.
Program Implementation and Monitoring
The City of Petaluma shall be responsible for overall implementation and administration of the Mitigation
and Monitoring Program. The City may partner with others, such as tertiary and secondary water users,
who will need to implement the Program as well. The City shall designate a Coordinator to oversee
implementation of the mitigation measures and ensure they are completed to the standards specified in the

Measures Included in the Project
This section presents a listing and description of measures and standards which have been incorporated
into the project design. These measures are denoted by the "PD" in the measure name. The City has
adopted these measures and incorporated them as part of the project in order to avoid or minimize
potential environmental impacts. These measures represent standard engineering, design, construction,
and maintenance practices. The process for the development of these measures began during the scoping
and early planning phase of the project. Measures were developed to change the project and avoid
potential impacts identified by the public and federal, state, and local agencies. Other measures were
developed as a result of air quality, noise, geotechnical, biological, cultural, and hydrological analysis in
order to avoid or minimize potential impacts.
Because these measures are part of the project, they do not qualify under the normal definition of
mitigation. However, these measures have been included in this chapter to provide a mechanism to
ensure that these measures are implemented and monitored, and to assist the reader in understanding the
commitments made by the City of Petaluma.
This section includes measures to be implemented in all phases of the project, including planning and
design, construction, operation, and maintenance. Compliance with these measures will result in
avoidance and /or minimization of adverse environmental impacts.
Mitigation Measures
This section contains a listing and description of mitigation measures recommended in Chapter 4
Environmental Analysis. The mitigation measures listed in this section are recommended by the
consultant team to avoid or reduce environmental impacts. As described above under Background, the
City is required to mitigate impacts whenever it is feasible. Mitigation measures will be adopted by the
City at the time of project approval. At that time, the City has the option of approving alternate
mitigation measures, if they can be shown to be effective and feasible.
Some of the mitigation measures will only be implemented during the final planning and detailed design
of the project. They often require the refinement of the final project design to accommodate particular
environmental constraints Other mitigation measures are intended to be implemented prior to, during,
and immediately following project construction. These measures generally require the construction
manager to follow certain constraints during construction and to repair and rehabilitate impacts resulting
from construction of the project. Finally, there are mitigation measures to be implemented during
operation of the project. These measures generally require monitoring of operations over time and the
modification of those operations to reduce adverse environmental impacts. Compliance with all of these
measures would result in the reduction of adverse environmental impacts.

PD -8 Seismic Design to Resist Ground Shaking
The City of Petaluma shall reduce the risk of damage to facilities from strong ground shaking to the
extent feasible. All project facilities sites are located in strong ground shaking areas due to the proximity
of the San Andreas and Rogers Creek faults.
Construction of all facilities and earth embankments shall incorporate earthquake- resistant design and
materials that meet or exceed the current seismic engineering standards of the Uniform Building Code
Seismic Zone 4 requirements. To decrease the amount of damage or period of interruption that may occur
during a seismic event, the City of Petaluma may elect to increase the performance objective for a given
facility beyond the code adopted minimums depending on the additional costs that may be incurred and
site specific design considerations that may be required.
Building codes are not intended to be applicable to some types of pipelines, pump station equipment that
are not enclosed, and other types of non - building structures. However, there are generally accepted
"consensus" standards that can be applied in a similar manner to adopted building code performance
objectives. For all non - building structures, "consensus" standards will be used, when available, to set
minimum performance objectives that allow for changes to occur to a pipeline or equipment during a
seismic event but damage to be minimal.
Again, the City of Petaluma may choose to raise the performance objective for a given non - building
element beyond the "consensus" standard or minimum recommendation by the structural engineer, design
specifications to decrease the amount of damage or period of interruption, depending on additional costs
and require site specific design considerations.

• Local police, public works and fire departments for each jurisdiction (city, county and state)
where construction is expected to occur, shall receive advance notification of construction
activities. Local residents and businesses shall also be notified and access shall be maintained if
possible.
• Remove and clear away dry, combustible vegetation from construction sites in those areas that
contain substantial forest fire risks and hazards, or are very high fire hazard severity zones as
defined by California Division of Forestry and Fire Protection. Grass and other vegetation less
than 18 inches in height above the ground may be maintained where necessary to stabilize the soil
and prevent erosion. Vehicles shall not park in areas where exhaust systems contact combustible
materials. Fire extinguishers shall be available on the construction site when working in high fire
hazard areas to assist in quickly extinguishing any small fires. The Construction Manager shall
have on site the phone number for the local fire department(s) and shall have a phone available
when working in high fire hazard areas should additional fire fighting capabilities be required.
• Prior to construction, retain a Registered Environmental Assessor (REA) to perform a Hazardous
Material Project Assessment following portions of the American Society of Testing Materials
(ASTM) guidelines along pipeline corridors and near other project facilities to identify potential
hazardous waste sites that may affect construction activities. If hazardous waste sites are
discovered, during construction the City shall survey all pipeline alignments for contaminated soil
and /or groundwater, recording the location, extent, and type of contamination.
• In the vicinity of hazardous materials /waste release sites, construction activities related that
require excavation or exposure of soil or groundwater shall be monitored by the contractor for
subsurface contamination. The City shall notify responsible agencies if any hazardous
materials /wastes are encountered. Monitoring shall include, at minimum, visual observation by
personnel with appropriate hazardous materials training, including 40 hours of Hazardous Waste
Operations and Emergency Response (HAZWOPER) training.
• In the vicinity of hazardous materials /waste release sites, groundwater brought to the surface as a
result of construction dewatering shall be handled in a manner appropriate to the construction
related permits for dewatering. If contamination is suspected or noted during the construction
phase, then the groundwater shall be containerized and analyzed for contamination by a
laboratory, certified by the California Environmental Protection Agency (CalEPA) Environmental
Laboratory Accreditation Program (ELAP), using United States Environmental Protection
Agency (USEPA)- approved analytical methods. Where contaminated groundwater is
encountered, precautions shall be taken to assure that the installation of piping or other
construction activities do not further disperse contamination.
• All potentially contaminated materials encountered during construction shall be evaluated in the
context of applicable local, state and federal regulations and /or guidelines governing hazardous
waste. All materials deemed to be hazardous shall be remediated and /or disposed of in
accordance with the most recent edition of applicable federal, state, and local regulations,
standards, laws, ordinances and codes including, but not limited to, those applicable to worker
and public safety, training, licensing and certifications, compliance notifications, abatement,

PD -13 Minimize Temporary and Permanent Visual Impacts
The City shall avoid or substantially lessen impacts by reducing construction disturbance, relocating
facilities, or using design features to decrease visual contrast. Measures may include:
• The size of construction zones and staging areas may be the minimum operable size. The
location of such zones would be adjusted to minimize the visual impacts.
• Alignments and locations of facilities may be adjusted to avoid visually sensitive features and
conditions that would result in major landform alteration or mature landscape removal. Visually
sensitive features may include significant stands of oaks and other mature trees, visually
significant rock outcroppings, highly visible steep slopes, and highly visible roadside foreground
areas. Facilities may need to be sited away from visible ridgelines.
• On visual edges such as ridgelines, low profile design approaches for facilities, including above
ground pipelines, may be employed. Roads and pipelines may be designed to lie parallel to
existing terrain contours to minimize the visual contrast.
• Utilize local rock types for road and pad surfacing material to minimize color contrast between
engineered and natural land forms.
• Provide for painting the pump station, control buildings, noise barriers and accessory structures a
natural color, where applicable. Screening may also take the form of architectural remedies such
as designing a pump station to appear as a structure that would blend with the surrounding
neighborhood.

or its occupied or critical habitat. For state - listed species, the City shall obtain the appropriate
authorization (Section 2081) from the California Department of Fish and Game authorizing take of the
state - listed species or its occupied habitat. As part of this process, the Project shall submit a site - specific
mitigation and compensation program for the affected resource acceptable to U.S. Fish and Wildlife
Service, the National Marine Fisheries Service, or the California Department of Fish and Game, as
applicable. If a species is listed as endangered, rare, or threatened by the state or U.S., and either the
habitat or individuals are found to occur within the study area and cannot be avoided, compensatory
actions (examples of which are described below) shall be undertaken such that the number of individuals
is not reduced and the range of the species is not restricted.
Avoidance and compensatory measures which may be required for specific species are listed below:
California Clapper Rail
• Construction activity in occupied California Clapper Rail habitat may be limited to occur
outside the breeding season for this species during the time frame of September 1 through
January 15.
• A minimum 200 -foot buffer may be required to be clearly delineated around the
boundary of occupied California Clapper Rail habitat that is located adjacent to a
construction zone.
• Within occupied habitat, construction may be limited to the minimum width corridor
possible and not greater than 15 meter (50 feet) wide. The perimeter of the construction
corridors may need to be clearly delineated.
• Staging and materials storage areas may need to be located outside of occupied habitat
for California Clapper Rail,

California Tiger Salamander
• The Project may need to avoid construction activities in all breeding ponds occupied by
California tiger salamanders.
• The Project may need to avoid construction activities in California tiger salamander
terrestrial habitat within 500 meters (1640 feet) of a known breeding pond. Between 500
meters and 2000 meters of a known breeding pond, construction or ground disturbing
activities may be limited to occur in suitable terrestrial habitats (i.e., annual grasslands or
oak savanna) that are contiguous to the known breeding pond unless the habitat is shown
to be unoccupied through protocol -level surveys.
• Construction activities in occupied habitat may need to be limited to the dry season (June
through October) when salamanders are not moving between terrestrial habitat and
aquatic breeding habitat.
• Compensation for impacts to California tiger salamander habitat may need to include
programs that address the various life stages of this species and would include purchase
of mitigation credits or creation of habitat equivalent to the loss of habitat value.
California Red - legged Frog
• The Project may need to use tunneling methods to cross creeks occupied by California
red - legged frogs. If needed, bore pits may need to be located outside the riparian corridor
along occupied frog streams and no vegetation would be removed along the streambank.
• All storage and staging area may need to be located outside of California red - legged frog
habitat.
• Preconstruction surveys may need to be conducted in potential habitat areas by qualified
biologists at least two weeks before initiation of activities in California red - legged frog
habitat. If any life stage of the California red - legged frog is found within the project area,
the City would need to contact the U.S. Fish and Wildlife Service for permission to move
the animals or larvae. If movement of the animals is approved, a Service- approved
biologist may need to move the animals to an appropriate area within the same stream. A
Service- approved biologist may need to monitor all work within potential California red -
legged frog habitat.
• When work within a creek or pond occupied by California red - legged frogs cannot be
avoided, work may need to be completed between April 1 and November 1. The work
area may need to be limited to the minimum necessary to complete the project, and creek
crossings should not exceed 15 meters (50 feet) in width.
• Streams that are temporarily impacted by construction activities may require stream
contours to be returned to their original condition.
• If permanent impacts to California red - legged frog habitat (i.e., ponds and streams) occur,
they may need to be mitigated by creation of new habitat. Created ponds would have a
hydroperiod sufficient to allow completion of breeding and larval development but be
designed to dry completely by the fall to avoid colonization by predators. U.S. Fish and
Wildlife Service may establish a buffer up to 300 feet around red - legged frog habitat.
• Severely trimmed or removed riparian vegetation may need to be replaced.

California Freshwater Shrimp
• The Project may need to use tunneling methods to cross creeks where the crossing
location is occupied by California freshwater shrimp. If required, bore pits may need to
be located outside the riparian corridor along occupied shrimp streams and no vegetation
would be removed along the streambank.
• Construction activities may need to be restricted to the dry season (low flow period) to
minimize transport of material from the project area downstream.
• Project areas that are adjacent to streams that provide habitat for California freshwater
shrimp may need to be surveyed prior to project activities (including removal of.
streamside vegetation) to insure that California freshwater shrimp are not present within
the project area or downstream of the project area.
• Riparian vegetation that extends over or into the water or that has roots extending into the
water may need to be preserved in a stream occupied by California freshwater shrimp.
Riparian vegetation that does not provide cover or foraging areas for shrimp may be
trimmed or removed. The amount disturbed may need to be restricted to the minimum
necessary to complete the project. Severely trimmed or removed vegetation would be
replaced.
Steelhead (Central California Coastal ESQ)
• The Project may need to use tunneling methods to cross creeks with 1) surface flow at the
time of construction and 2) occupied at the time of construction by steelhead. If bore pits
are required, they may need to be located outside the riparian corridor along occupied
streams and no vegetation would be removed along the streambank.
• Riparian vegetation that extends over or into the water or that has roots extending into the
water may need to be preserved in streams occupied by steelhead. Vegetation that does
not provide shade or shelter for this species may be trimmed or removed, subject to
measures stipulated in the Biological Opinion or Section 10 permit for this species. The
amount disturbed may need to be the minimum necessary to complete the project.
Severely trimmed or removed vegetation shall be replaced.
For Aquatic Species (California Tiger Salamander, California Red - legged Frog,
California Freshwater Shrimp, Steelhead)
Equipment maintenance and fueling areas for mobile equipment may need to be located
at least 30 meters (100 feet) away from the creek bank. Fueling would be behind a
containment barrier that would prevent any spilled or leaked fuel from running into the
creek. Servicing of mobile equipment may need to be limited to within designated areas
away from sensitive habitats. Motorized equipment used during construction or
demolition activities may need to be checked for oil, fuel, and coolant leaks prior to
initiating work. Any equipment found to be leaking fluids would not be used in or within
30 meters of aquatic habitat features to minimize the chances of contaminating the
habitat.
An erosion control plan and emergency response and cleanup plan may need to be
prepared prior to beginning work adjacent to streams. The plan would detail the methods
to contain sediment runoff into the creek and to contain and cleanup spills of petroleum
products or other hazardous materials in the work area.

• If permanent impacts to salt marsh harvest mouse habitat occur, they shall be mitigated
by creation of new habitat equivalent to the habitat value lost.
• Hand removal of salt marsh vegetation that the salt marsh harvest mouse relies upon may
be necessary to avoid take of this species.
• Installation of a barrier exclusion fence may be necessary to prevent salt marsh harvest
mice from entering the work area.
• The Project may need to use tunneling methods to cross underneath salt marsh harvest
mouse habitat.
Listed or CNPS List 1B Plants
• Listed or List 113 plants within the project footprint may need to be transplanted to a
mitigation site approved by the California Department of Fish and Game and U.S. Fish
and Wildlife Service. Seed from plants unavoidably impacted may need to be collected

The City of Petaluma shall avoid permanent impacts to protected trees (as defined by local Tree
Ordinances or such regulations that are in effect at the time of start of construction), to the extent feasible.
If permanent impacts cannot be avoided, sensitive trees and plant communities shall be replaced or
restored. Measures may include:
• If permanent impacts to sensitive trees are found to occur in the project area and cannot be
avoided, then the City may develop a site - specific compensatory program for the affected
resource. The compensatory program must be acceptable to the appropriate agency.
• Trees larger than 6 inches in diameter may be subject to protection and compensation.
• Protected trees, their protected perimeters and whether they are to be retained or removed would
need to be clearly shown on all improvement plans.
• Before the start of any work on the site, trees designated for protection on the approved site plan
may need to be clearly delineated with a substantial barrier (steel posts and barbed wire or chain
link fencing) at the protected perimeter, or limits established during the permit process. The
delineation markers would remain in place for the duration of all work. A certified arborist may
be needed to inspect trees within or adjacent to project area prior to initiation of construction
activities.
• When it is necessary to limb trees, prune branches, or prune roots within the right -of -way, work
may need to be conducted by a certified arborist in accordance with accepted arboricultural
practices, including the pruning standards published by the California Department of Forestry
(Coast Region). This work would occur only as a means of protecting trees from damage or
removal.
• Trees to be removed may need to be clearly marked. Where practicable, trees and shrubs would
be salvaged for replanting in temporarily disturbed areas. Where proposed facilities or
construction activities must encroach upon the protected perimeter of a protected tree, special
measures may be needed to avoid compaction and allow the roots to obtain oxygen, water, and
nutrients.

Lane improvements. Based on the APE and coordination with the SWRCB the following
additional tasks may be necessary:
• Conduct additional archaeological survey and either augment the existing Archeological Survey
Report or prepare a new expanded report based on the agency consultation;
• Evaluate the significance of any identified resources, in consultation with the State Historic
Preservation Officer (SHPO);
• Prepare a Finding of (No) Historic Properties Affected; or a Finding of Adverse Effect; and
• Develop and implement a Treatment Plan to resolve any identified adverse effects.
• Because of the possible presence of subsurface archeological resources in the vicinity of the
pipeline route, prior to the start of construction core samples shall be taken along a portion of the
Ielmorini pipeline route by a qualified archeologist. A Treatment Plan outlining the procedures to
be taken in the event archeological or cultural materials are found will be prepared prior to the
core samples being taken. The number and location of the core samples shall be determined in
coordination with representatives of the Sacred Sites Protection Committee of the Federated
Indians of Graton Rancheria, and SWRCB. Based on the results of the core samples, a

The City of Petaluma shall avoid impacts to cultural resources, to the extent feasible. The treatment of
cultural resources to be affected by the Project shall be addressed under applicable cultural resource laws
and regulations. Consultation to address potential adverse effects to cultural resources may involve
interested parties, and any additional agencies which assert jurisdiction over the project.
A four -step process shall be implemented to address potential impacts and the requirements of the cultural
resource laws and regulations. Once the final Area of Potential Effects (APE) for the project is selected,
the first step will be identification of cultural resources within the APE. If cultural resources are
identified, the second step will require that these resources be evaluated under appropriate significance
criteria, in consultation with the State Historic Preservation Officer (SHPO), if necessary. If the resources
are significant, the third step will be to determine whether they will be adversely affected by the project.
The fourth step will involve avoidance or mitigation of any adverse effects to significant resources.
Measures to minimize impacts may include:
• Designing project actions to conform with the Secretary of the Interior's Standards for the
Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring and
Reconstructing Historic Buildings;
• Adhering to the city's Historic Commercial District Design Guidelines;
• Conducting archaeological data recovery in accordance with a research design approved by the
