SUBJECT: Resolution Certifying Addendum No. 2 to the Program Environmental Impact
Report for the Water Recycling Expansion Program Certified by Resolution No.
2008-206 N.C.S.
RECOMMENDATION
It is recommended that the City Council adopt the Resolution Certifying Addendum No. 2 to the
Program Environmental Impact Report (EIR) for the Water Recycling Expansion Program
(WREP) Certified by Resolution No. 2008-206 N.C.S.
BACKGROUND
The City of Petaluma delivers recycled water to urban users within the City, which includes
parks, open spaces, golf courses, and schools, and to agricultural customers outside the City
limits. Historically, the water delivered to agriculture was secondary treated wastewater. In 2013,
the City began delivering tertiary treated recycled water, defined as secondary treated wastewater
with additional filtration and ultraviolet light disinfection, for all urban and agricultural uses.
The City recently completed a pipeline to extend recycled water service along the urban growth
boundary to the east of the City to serve parks, schools, and landscape areas within City limits.
The City has also recently connected agricultural properties to the recycled water system in the
vicinity of Adobe and Frates Roads. As a result of these improvements and of growing demand
outside the existing approved recycled water delivery area, an expansion is needed and the first
step is to take the proposed California Environmental Quality Act (CEQA) action.
On December 7, 2015, Council adopted Resolution 2015-187 N.C.S. approving Addendum No. 1
to the WREP EIR which expanded the recycled water service area boundaries by adding 18 rural
parcels at the southeastern boundary of the service area.
DISCUSSION
The recent drought demonstrated the value of a reliable supply of water for irrigation purposes.
As the recycled water system has expanded, owners of properties adjacent to these projects have
expressed interest in connecting to the system. To serve these properties, the City's recycled
water service area boundaries must be expanded. The proposed expansion would extend to
Adobe and Corona Roads to the northeast of the City, and would incorporate properties on both
sides of Adobe Road to the east of the City. In selecting the service area boundaries,
consideration was given to recycled water applications submitted from new customers, other
interest expressed by property owners, and proximity to existing or planned pipelines and
customers. Approximately 100 rural parcels, large and small, would be added to the service area,
although not all are expected to request or receive recycled water.
Because many of the properties targeted for service by recycled water are outside of, but in
proximity to, service areas identified in the Water Recycling Expansion Project Environmental
Impact Review, it is recommended that Council adopt a second Addendum to the WREP EIR to
expand the recycled water service area boundary to comply with the CEQA. The expansion of
the service boundary is consistent with the WREP, for which an EIR was certified by the Council
in 2008 by Resolution 2008-206 N.C.S. As discussed on pages 4-8 of the WREP EIR Addendum
2, in Attachment 2, none of the events outlined in CEQA Guideline section 15162 has occurred,
which would trigger the need to prepare a subsequent EIR.
Because new properties included within the revised Service Area Boundary are similar to
properties within the existing service boundary, no new effects will occur and no new mitigation
measures are required. These properties are rural and actively involved in farming activity with
vegetation, soil types, and ground slopes similar to the existing service area. 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 terms and conditions of the City's standard recycled
water agreement are consistent with the WREP and its EIR.
To serve the additional parcels along Adobe Road that are within the proposed expanded service
area, a pipeline extension will be designed and a CEQA review conducted. The new users will
bear the cost for design, permitting and construction of the pipeline extension to serve their
properties. Revenues from two recycled water applications currently submitted for parcels in the
expanded service area are expected to be $154,800 annually beginning in 2019. The users have
requested 180 acre-feet per year, which is about 14 percent of the total recycled water distributed
in 2017. These new revenues are sufficient to support the planning and CEQA work for the
expanded service area.
FINANCIAL IMPACTS
The preliminary 2019 annual budget for the recycled water program within the wastewater
enterprise fund is $1,106,922 and will cover the costs of treatment, pumping, pump and pipe
repairs, maintenance, customer service, metering, and billing.

Petaluma Water Recycling Expansion Program EIR Addendum #2
Introduction
In 2008 the City of Petaluma certified the Water Recycling Expansion Program (WREP) 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 storage 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.
In 2015, the City prepared an Addendum to the WREP EIR to expand the Recycled Water Service Area
boundary and update a Project Measure. Now the City is proposing to expand the Recycled Water Service
Area again, this time to the east along Adobe Road.
Applicability and 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;
(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 EI R 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.

Petaluma Water Recycling Expansion Program EIR Addendum #2
The change in environmental impacts due to the proposed Project modifications or changed conditions
have been evaluated and measured against the standards set forth in paragraphs 1, 2, and 3 above to
determine whether an Addendum is appropriate or a subsequent EIR is needed. The environmental
analysis below provides the detailed examination of each of these issues. The conclusion is that none of
the circumstances which might require a subsequent or supplemental EIR has occurred, and that an
Addendum is, therefore, appropriate.
This Addendum should be read together with the full text of the 2008 WREP EIR. Even though
modifications to the adopted Project are minor, the modifications have been subjected to a detailed
analytical process consistent with the methodology applied in the 2008 EIR.
Section 15164 of the Guidelines implementing the California Environmental Quality Act ("CEQA") provides
that an Addendum is the appropriate level of CEQA analysis when the circumstances defined in Section
15162 calling for preparation of a Subsequent EIR do not occur. None of the circumstances that require a
Subsequent EIR, such as new significant impacts or significant impacts of a substantially more severe
nature, is present. Thus, an Addendum is the appropriate level of CEQA analysis and the appropriate
method of amending the 2008 EIR.
Modifications to the Project and Changes in Circumstances
Location of Project Modifications
The Project modifications would add approximately 2,900 acres to the Recycled Water Service Area along
the eastern edge of the current Recycled Water Service Area Boundary'(see Figure 2-2, Revised Concept
Plan).
The City has been approached by several agricultural property owners located east of the City who are
desirous of receiving recycled water for irrigation. Even though the properties are located outside of the
existing Recycled Water Service Area, the addition of these properties would support the objectives of the
WREP to reduce wastewater discharges and provide additional recycled water for agricultural irrigation.
Therefore, the City proposes to amend the Recycled Water Service Area, as defined in Figure 2-2 (Concept
Plan) of the WREP EIR and revised in the 2015 EIR Addendum, to extend it along Corona Road northeast
to Adobe Road, and north along Manor Lane and Manor Lane West approximately one mile north of Adobe
Road. The new properties that would be included within the expanded Service Area are similar to the rural
agricultural properties currently within the Service Area.
Proposed Modifications to the Project
The proposed modifications would change only the Recycled Water Service Area, allowing recycled water
irrigation to occur within a larger area than currently allowed. No other portions of the WREP would change.
Activities that could occur within the revised Recycled Water Service Area 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. The volume of recycled water
(1,070 million gallons per year) available for distribution would remain the same as analyzed in the WREP
EIR. Expansion of the 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 Recycled Water Service Area is not
anticipated to increase the overall length of pipe to be installed.
March 2018 Page 3
Petaluma Water Recycling Expansion Program EIR Addendum #2
Changed Circumstances
No relevant 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
impacts of the additional service area would be different than identified in the WREP EIR. New special -
status species have been identified that may potentially occur within the existing and expanded Recycled
Water Service Area; please refer to the Biological Resources analysis below for the change in the analysis
relative to these species.
Environmental Analysis
This section consists of 12 environmental resource categories analyzed in the WREP EIR, each of which
presents the analysis of the Project modifications within that environmental discipline. The analysis refers
back to the original evaluation of impacts contained in the 2008 WREP EIR and identifies the change in
impacts, if any, from the Project approved at that time. If there are no changes to the previous impact
evaluation, an explanation for this conclusion is provided.
Most of the information presented in the 2008 EIR has not changed and is not repeated here. Please refer
to the 2008 WREP EIR for descriptions of setting, discussion of methodology, and the complete
identification and discussion of impacts.
The new properties that would be included within the revised Recycled Water 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 are also similar. Program activities that
could occur within the revised Recycled Water 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 resource
categories, no new impacts were identified and all mitigation measures would still be applicable. The
following is a summary of the key findings.
4.1 Land Use
The proposed Project modifications do not require revisions to the evaluation of Land Use. The irrigation
of additional agricultural parcels with recycled water and the construction and operation of pipelines to
convey recycled water are consistent with the land uses within the revised Recycled Water Service Area
boundary. The additional properties within the revised boundary would not be located within areas classified
as MRZ-2 for mineral resources (California Geological Survey 2013). Therefore, the analysis and impacts
relative to mineral resources in the WREP EIR are adequate for the revised service area. Project
Description (PD) Measure 1, Site and Design Facilities to Achieve Compatible Land Use, would apply to
the Project modifications. The modifications would not result in new significant impacts or substantially more
severe significant impacts relative to land use.
4.2 Agriculture and Soil Quality
The proposed Project modifications do not require revisions to the evaluation of Agriculture and Soil Quality.
The irrigation of additional agricultural parcels with recycled water and the construction and operation of
pipelines to convey recycled waterwould support agriculture in the expanded Recycled Water Service Area.
PD -16, Implement BMPs for Runoff, Erosion, and Agricultural Chemical Use as modified by the 2015
Addendum to the WREP EIR, and Mitigation Measure AG -1, Purchase Locally Grown or Inspected Plants,
March 2018 Page 4
9
Petaluma Water Recycling Expansion Program EIR Addendum #2
would apply to the Project modifications. The modifications would not result in new significant impacts or
substantially more severe significant impacts relative to agriculture and soil quality.
4.3 Geology, Soils, and Seismicity
The proposed Project modifications do not require revisions to the evaluation of Geology, Soils, and
Seismicity. The irrigation of additional agricultural parcels with recycled water and the construction and
operation of pipelines to convey recycled water would not expose the persons residing in the area or
properties to be added to the Service Area to additional geological hazards beyond those already existing.
The soils and geology in the expanded Service Area are similar to those evaluated in the WREP EIR. PD -
3, PD -4, PD -5, PD -6, PD -7, and PD -8 would apply to the Project modifications. The modifications would
not result in new significant impacts or substantially more severe significant impacts relative to agriculture
and soil quality.
4.4 Hydrology and Water Quality
The proposed Project modifications do not require revisions to the evaluation of Hydrology and Water
Quality. The irrigation of additional agricultural parcels with recycled water and the construction and
operation of pipelines to convey recycled water would occur in a similar manner as that described for the
agricultural properties within the existing Recycled Water Service Area. The risk of erosion, siltation,
degradation of groundwater quality, etc. would be similar to that evaluated in the WREP EIR, because the
expanded Service Area has similar types of topography, surface and groundwater resources, land uses,
and flooding issues as the agricultural areas already evaluated in the WREP EIR. PD -2, PD -3, PD -14, PD -
16, and PD -17 would apply to the Project modifications. The modifications would not result in new significant
impacts or substantially more severe significant impacts relative to hydrology and water quality.
4.5 Air Quality
The proposed Project modifications do not require revisions to the evaluation of Air Quality, including the
evaluation of greenhouse gas emissions. The irrigation of additional agricultural parcels with recycled water
and the construction and operation of pipelines to convey recycled water would not expose the persons
residing in the area to additional air pollutant levels beyond those previously identified. The pattern of rural
residential uses in a predominantly agricultural area in the expanded Service Area is similar to those
evaluated in the WREP EIR. PD -20, Air Quality Protection, and the Mitigation Measures assigned to Impact
3.10-6 in Petaluma's General Plan 2025 EIR would apply to the Project modifications. The modifications
would not result in new significant impacts or substantially more severe significant impacts relative to air
quality and greenhouse gas emissions.
4.6 Noise
The proposed Project modifications do not require revisions to the evaluation of Noise. Since certification
of the WREP EIR, Sonoma County has adopted a new General Plan. However, the new Noise Element
uses the same noise standards that were in the applicable Noise Element at the time the WREP EIR was
prepared and certified. Therefore, the threshold of significance for County parcels remains the same as
previously analyzed. The irrigation of additional agricultural parcels with recycled water and the construction
and operation of pipelines to convey recycled water would not expose the persons residing in the area to
additional noise levels beyond those previously identified. The rural residential uses in the expanded
Service Area are similar to those evaluated in the WREP EIR. PD -19, Construction Noise Control, would
March 2018 Page 5
10
Petaluma Water Recycling Expansion Program EIR Addendum #2
apply to the Project modifications. The modifications would not result in new significant impacts or
substantially more severe significant impacts relative to noise.
4.7 Public Health and Safety
The proposed Project modifications do not require revisions to the evaluation of Public Health and Safety.
The irrigation of additional agricultural parcels with recycled water and the construction and operation of
pipelines to convey recycled water would not expose employees or persons residing in the area to additional
public health or safety hazards beyond those previously identified. The pattern of rural residential uses in a
predominantly agricultural area in the expanded Service Area is similar to those evaluated in the WREP
EIR. PD -9, Construction Management Program, and PD -16, Implement BMPs for Runoff, Erosion, and
Agricultural Chemical Use would apply to the Project modifications. The modifications would not result in
new significant impacts or substantially more severe significant impacts relative to public health or safety.
4.8 Biological Resources
The irrigation of additional agricultural parcels with recycled water and the construction and operation of
pipelines to convey recycled water would not impact biological resources such as wetlands, riparians areas,
or trees differently than the impacts previously identified. The types of vegetation communities, surface
waters, and wildlife habitats in the expanded Service Area are similar to those evaluated in the WREP EIR.
PD -2, Revegetate Temporarily Disturbed Sites, and PD -21, Riparian and Sensitive Habitat Protection, as
well as Mitigation Measures 13I0 -1a, 13I0-1 b, 13I0 -2a, 13I0-3, 13I0 -4a, 13I04b, and BIO -5 would apply to the
Project modifications.
However, the potential for additional special -status species has been identified within the existing and
proposed addition to the Recycled Water Service Area. According to a new search of the California
Department of Fish and Wildlife California Natural Diversity Database, potential habitat for two amphibians
that were not identified in the WREP EIR, the California giant salamander (Dicamptodon ensatus) and red -
bellied newt (Taricha rivularis), may occur. Impacts to these amphibian species or their habitat, for example,
from pipeline construction, would be a significant impact. However, the WREP EIR identified a significant
impact for special -status species under Impact 13I0-1 and included Mitigation Measure 13I0 -1a, Avoid the
Loss of Candidate, Sensitive, or Special Status Species and their Habitat, which includes avoidance and
compensatory measures for amphibians which would reduce potential impacts to California giant
salamander and red -bellied newt to a less -than -significant level. Therefore, there would be no new
significant impact and the implementation of the existing Mitigation Measure 13I0-1 a would result in a less -
than -significant impact to these species, should they be found to be present.
Similarly, the potential also exists for the following special -status plant species to occur in the existing and/or
revised Recycled Water Service Area: Pitkin Marsh lily (Lilium pardalinum ssp. pitkinense), Sonoma zerene
fritillary (Speyeria zerene ssp. Sonomensis), big -scale balsamroot (Balsamorhiza macrolepis), congested -
headed hayfield tarplant (Hemizonia congesta ssp. Congesta), golden larkspur (Delphinium luteum), marsh
microseris (Microseris paludosa), oval -leaved viburnum (Viburnum ellipticum), pappose tarplant
(Centromadia parryi ssp. Parryi), and saline clover (Trifolium hydrophilum). Impacts to these special -status
plant species or their habitat, for example, from pipeline construction, would be a significant impact.
However, the WREP EIR identified a significant impact for special -status plant species under Impact 1310-
1 and included Mitigation Measure 13I0 -1a, Avoid the Loss of Candidate, Sensitive, or Special Status
Species and their Habitat, which includes avoidance and compensatory measures which would reduce
potential impacts to these additional plant species to a less -than -significant level. Therefore, there would
March 2018 Page 6
11
Petaluma Water Recycling Expansion Program EIR Addendum #2
be no new significant impact and the implementation of the existing Mitigation Measure BIO -1 a would result
in a less -than -significant impact to these species, should they be found to be present.
Therefore, the Project modifications would not result in new significant impacts or substantially more severe
significant impacts relative to biological resources.
4.9 Transportation
The proposed Project modifications do not require revisions to the evaluation of Transportation. The
irrigation of additional agricultural parcels with recycled water and the construction and operation of
pipelines to convey recycled water would not cause impacts to congestion, traffic safety, or emergency
access beyond those previously identified. The pattern of rural roadways in the expanded Service Area is
similar to those evaluated in the WREP EIR. PD -11, Standard Traffic Control Procedures, would apply to
the Project modifications. The modifications would not result in new significant impacts or substantially more
severe significant impacts relative to transportation.
4.10 Cultural Resources
The proposed Project modifications do not require revisions to the evaluation of Cultural Resources. The
irrigation of additional agricultural parcels with recycled water and the construction and operation of
pipelines to convey recycled water would not cause impacts to historic resources, agricultural resources,
or paleontological resources beyond those previously identified. Unknown cultural resources could occur
within the additional properties. However, the WREP's Mitigation Measure CR -1 b, Identify and Avoid or
Minimize Impacts to Cultural Resources, outlines a four -step process to identify and avoid or minimize
impacts to cultural resources. Mitigation Measure CR -2, Evaluation and Treatment of Paleontological
Resources, would also apply to the Project modifications. The modifications would not result in new
significant impacts or substantially more severe significant impacts relative to cultural resources.
Because the WREP EIR was completed in 2007, and these proposed modifications do not constitute a new
project as defined by CEQA, notifications to local Native American Tribes under AB52 are not required.
4.11 Visual Resources
The proposed Project modifications do not require revisions to the evaluation of Visual Resources. The
irrigation of additional agricultural parcels with recycled water and the construction and operation of
pipelines to convey recycled water would not cause impacts to Community Separators, Urban Separators,
Scenic Landscape Units, glare, or views from scenic roads, ridgelines, or neighborhoods beyond those
previously identified. The pattern of rural residential uses in a predominantly agricultural area in the
expanded Service Area is similar to those evaluated in the WREP EIR. PD -2, PD -13, and PD -15 would
apply to the Project modifications. The modifications would not result in new significant impacts or
substantially more severe significant impacts relative to visual resources.
4.12 Public Services, Utilities, and Energy
The proposed Project modifications do not require revisions to the evaluation of Public Services, Utilities,
and Energy. The irrigation of additional agricultural parcels with recycled water and the construction and
operation of pipelines to convey recycled water would not cause increased demand for services and energy
and would not conflict with utilities more than previously identified. The increased Service Area would not
increase the volume of recycled water (1,070 million gallons per year) for distribution that was analyzed in
the WREP EIR. The increased Service Area simply allows flexibility in where the recycled water is
distributed. Energy use would therefore be similar to that analyzed in the WREP EIR.
March 2018 Page 7

Petaluma Water Recycling Expansion Program EIR Addendum #2
PD -11, Standard Traffic Control Procedures, and PD -14, Adjust Facility Design to Avoid Wells and Septic
Systems, would apply to the Project modifications. The modifications would not result in new significant
impacts or substantially more severe significant impacts relative to public services, utilities, and energy.
