BACKGROUND The City of Petaluma delivers tertiary treated recycled water produced by the Ellis Creek Water Recycling Facility ( ECWRF) to urban users within the City limits to irrigate parks, open spaces, golf courses, and schools and outside the City limits to agricultural customers. The opening of the ECWRF in 2009 allowed the City to produce tertiary recycled water, which is suitable for non - potable uses such as irrigation. On November 16, 2015, a Recycled Water System Update was presented to Council, highlighting the master plan for the expansion of the City's Urban and Agricultural recycled water systems. The Urban and Agricultural Recycled Water Master Plan identified specific project alignments and phasing to expand the City's recycled water system. The expansion of the recycled water system was separated into four categories: Prop IA, Phase 1, Phase 2, and Phase 3, as shown in Attachment 3. The two subject projects are in the Prop IA phase of the updated Master Plan and are scheduled to go to construction this summer and next. The Program Environmental Impact Report (PEIR) for the expansion of recycled water for urban and agricultural uses was prepared in 2008 and tiered off the EIR for the 2025 General Plan. The Water Recycling Expansion Program (WREP) is an essential component of the water resources element of the General Plan because water recycling provides potable water offset. The City Council certified the PEIR for the WREP in 2008 (Resolution 2008 -206). Council certified Addendum No. 1 to the PEIR for the WREP and adopted an update to the PEIR's Mitigation Monitoring and Reporting Program (MMRP) in Resolution 2015 -187 N.C.S. on December 7, 2015. Addendum No. 1 addressed an expansion of the service area to include several agricultural properties to the southeast of the ECWRF but did not specifically identify the two proposed urban projects. The PEIR for the WREP is a project -level EIR for near -term projects identified in the EIR project description, and a program -level EIR for pipelines and use areas that were envisioned but not specifically identified as a discrete project in the EIR. Program -level projects, such as those addressed herein, are subject to site - specific environmental review and further Council approval. The recycled water use areas identified in the initial PEIR included urban uses, the two east -side golf courses, and agricultural and other rural properties in the vicinity of the ECWRF. For any project not specifically identified in original PEIR project description, City Council must determine whether the project falls within the scope of the PEIR and if it does, they must approve the projects and adopt a Mitigation Monitoring and Reporting Program (MMRP). The two proposed recycled water system extension projects, Oakmead Business Park — Phase 1 and Sonoma Mountain Pipeline, are not specifically identified in the initial PEIR and therefore require site - specific environmental review, approval, and a MMRP. DISCUSSION Two urban recycled water extension projects, Oakmead Business Park — Phase 1, and Sonoma Mountain Pipeline, are scheduled to go to construction in summer 2016 and summer 2017, respectively. The two projects are in the "Prop IA" phase of the Urban Recycled Water Master Plan presented to City Council on November 16, 2015, as shown on Attachment 3. The Oakmead Business Park -Phase 1 Project will extend a 2,250 =foot recycled water pipeline into the commercial Oakmead Business Park, directly adjacent to ECWRF. The project is expected to offset potable water use by approximately 8.93 million gallons per year. The Project will make recycled water available for irrigation to several local businesses along Cypress Drive and Pine View Way including the Kaiser Permanente medical facility. During the summer of 2017, the Sonoma Mountain Pipeline will extend recycled water service 8,000 feet along the City Urban Separator from Prince Park northwest to Corona Creek Elementary School. The Project will bring recycled water to several schools, City parks, and landscape assessment districts (LADS). The City is seeking Proposition 1 funding from the State Water Resources Control Board (State Board) for both projects, however the Prop 1 funding may not be in place before the Oakmead project begins construction. The proposed cost sharing agreement with Kaiser, addressed in a companion Council Agenda item, obviates the necessity of Prop 1 funding for the Oakmead Phase 1 project, though the City's share of the Oalcmead project may count towards the match requirements for the Prop 1 grant should such be awarded. The City must satisfy requirements of the California Environmental Quality Act (CEQA) for the projects, therefore the Council is asked to determine that the two proposed recycled water projects are within the scope of the PEIR for the WREP, to approve the projects, and to adopt an 2 MMRP. The technical review of these projects including justification for inclusion in the scope of the PEIR and the MMRP is included in the detailed CEQA checklist document contained in Attachment 2. Since Kaiser will pay for the majority of the costs of the Oakmead pipeline, it was decided to move forward with the Oakmead Phase 1 project this summer in order to expedite the availability of recycled water to the Kaiser campus. Staff prepared the project design documents and issued a Notice Inviting Bids on May 19, 2016. On June 8, 2016, five bids were received as follows: Name of Bidder Bid Total Team Ghilotti, Inc. $ 523,553.50 Lowest Responsible Bidder D &D Pipelines Inc. $ 583,635.00 Argonaut Constructors $ 604,088.00 Ranger Pipelines $ 654,210.00 WR Forde Associates $ 657,978.00 Engineer's Estimate $ 610,000.00 The lowest responsible bidder, Team Ghilotti, Inc. has performed similar projects for the City of Petaluma, City of St. Helena, Novato Sanitary District, Marin Municipal Water District, and the City of Rohnert Park. Staff verified that the Contractor possesses a valid Class A California Contractor's License, license number 895384, which expires on April 30, 2017, that is appropriate to perform the work. Construction is scheduled to begin in July 2016 and to be completed by September 2016. Construction management and inspection will be conducted by City staff. This action is consistent with General Plan 2025 Goal 8 -G -3: "Maximize the use of recycled water as a potable water offset to manage water demands, and to meet regulatory requirements for wastewater discharge." FINANCIAL IMPACTS As approved in the FY 16/17 CIP budget for the Recycled Water System Extension — Oakrnead Business Park Phase 1 Project (C66501633) is estimated to be $720,000 as summarized in the below table. The budget is sufficient to cover the increase over budget for the proposed construction contract with offsetting minor savings in design, construction management, and contingency line items. Project Costs Approved CIP Budget Revised Project Budget Construction Contract $ 500,000.00 $ 523,553.50 Planning/Environmental $ 10,000.00 $ 10,000.00 Design $ 50,000.00 $ 45,000.00 Administration $ 0.00 $ 5,000.00 Construction Management $ 75,000.00 $ 70,000.00 CIP Overheads $ 10,000.00 $ 10,000.00 3 Contingency $ 75,000.00 $ 56,446.50 TOTAL $ 720,000.00 $ 720,000.00 The City is seeking Prop 1 funding to reimburse the City - funded portion of the project, however, the project is not dependent on acquiring these funds. If Prop l funding is not authorized for this project, the project costs will be used as a match for any Prop 1 funds acquired for next year's Sonoma Mountain Pipeline project. At this time, it is anticipated that the project will be funded through the wastewater capital fund and a private cost -share funding agreement with Kaiser Permanente, for sixty -five percent of the construction costs. The budgeted funding sources are as follows: Funding Sources Approved CIP Budget Wastewater Capital Fund $ 343,000 Kaiser Permanente $ 377,000 Total $ 720,000 The CEQA requirements to determine inclusion of projects in the PEIR scope, for approval of the projects, and adopt the MMRP, do not have a financial impact.

The WREP EIR was certified by the Petaluma City Council on November 3, 2008 (Clearinghouse No. 2007052146). The WREP EIR is both a project -level and a program -level EIR. The program -level improvements include use of recycled water and recycled water pipelines, both of which are proposed as part of the 2016 Urban Recycled Water System Expansion Project. This Checklist has been prepared under Section 15168(c) of the CEQA Guidelines to document the evaluation of the site and the activity to determine whether the environmental effects of the project were covered in the Program EIR. This Checklist also serves as the evaluation pursuant to Section 15162 of the CEQA Guidelines of whether new significant effects have been identified or new mitigation measures would be required. Chapter 3 of this document is a Mitigation Monitoring Program tailored to this project, which serves to incorporate feasible mitigation measures developed in the Program EIR that are applicable to this project. The Checklist evaluation takes into consideration changes in the environmental setting, cumulative projects, and regulations that have occurred since certification of the WREP EIR in 2008. Summary of Results The 2016 Urban Recycled Water System Expansion Project is located within the WREP Area, as described in the WREP EIR, and includes recycled water pipelines and use of recycled water as evaluated in the program -level review in the WREP EIR. As concluded by this Checklist in Chapter 4, no new significant environmental effects have been identified, and no new mitigation measures are required as compared to the WREP EIR. Mitigation measures applicable to this project are identified in the Checklist table and also in the Mitigation Monitoring and Reporting Program in Chapter 3. This analysis concludes that the project is within the scope of the WREP EIR, and that none of the conditions listed in CEQA Guidelines Section 15162 would occur, and that, therefore, no further CEQA documentation is required. The WREP EIR is available at Petaluma City Hall at 11 English Street. 2016 Urban Recycled Water System Expansion Project - CEQA Checklist 9 Project Description Background and Purpose In the 1980's, the City began providing recycled water for the irrigation of pasture land to avoid summertime discharge to the Petaluma River in compliance with the City's discharge permit. Later, the City expanded its recycled water irrigation program by adding a vineyard on Lakeville Highway, Adobe Creek Golf Course, and Rooster Run Golf Course. In 2005, the City began constructing the Ellis Creek Water Recycling Facility (WRF). The future flow and loads for the facility were developed using historical data and future population projections as identified in the City of Petaluma 1987 -2005 General Plan, as well as the City's service agreement with Sonoma County for wastewater generated in Penngrove. The Ellis Creek WRF EIR and Addenda allow the production of up to 8 mgd of tertiary recycled water. The tertiary recycled water will be of the quality to support various uses allowed by Title 22 for tertiary recycled water, including irrigation of food and pasture crops; irrigation of landscaping, parks, and schools; industrial and commercial uses such as concrete mixing, car washes, and cooling towers; and indoor uses such as fire sprinkler systems and toilet flushing in commercial or institutional buildings. Recycled water use in 2014 was 729 MG for the year (Petaluma 2016). The relevant objectives of the Water Recycling Expansion Program are: • To enhance the water supply by providing recycled water for non - potable uses to create a new source of water that is sustainable, drought proof, and readily available within the City of Petaluma; • To recycle tertiary water effectively to remain in compliance with regulatory permit requirements during the period of restricted discharge to the Petaluma River (May 1 through October 20); • To meet regulatory requirements for reuse of approximately 1,025 to 1,070 million gallons (MG) a year of water through a flexible, economical program that provides water application locations in a drought or wet year making the program ecologically sustainable; • To provide a comprehensive, phased program to construct, improve and expand the facilities, conveyance systems and irrigation systems necessary for the distribution of recycled water to meet user demands and restricted discharge requirements as population buildout occurs under General Plan 2025; and • To provide tertiary recycled water for irrigation reuse applications, and other uses as permitted under Title 22, where the City is currently supplying potable water. Project Location The project is located in two areas, on the eastern side of the City and in the Oakmead Business Park south of Lakeville Highway, as shown in Figure 1, Vicinity Map. The project is located within the WREP Area, as shown in Figure 2, WREP Area, within the Petaluma city limits. 2016 Urban Recycled Water System Expansion Project— CEQA Checklist 2 10 Proposed Project The City of Petaluma proposes to expand its recycled water system by installing two new recycled water pipelines to allow recycled water use for irrigation of schools, parks, landscape assessment districts (LADS), and a commercial property. The Sonoma Mountain Pipeline alignment consists of 16 -inch PVC and 4 -inch PVC mains with lengths of 8,300 feet and 3,370 feet, respectively.. The Oakmead Business Park alignment would be 2,250 feet in length. Together, both pipelines would deliver sufficient recycled water to offset potable water use by 98.9 acre -feet per year. This expanded distribution system would allow delivery of recycled water to the schools, parks, and landscape areas along the pipeline alignments. The City has determined that expanding recycled water lines for irrigation within urban areas on the east side of the City and at the Oakmead Business Park to be the most cost - effective method to achieve a significant reduction in potable water demands at this time. All of the recycled water proposed for irrigation would offset existing potable water use, freeing up the potable water for more essential services. The eastern portion of the project is shown in Figure 3, Sonoma Mountain Pipeline Alignment. The Sonoma Mountain Recycled Water Line route would use primarily public right -of -way, both in streets and in the City's open space buffer, but also traverse some private land. The pipeline would be in the center of a 10 -foot wide construction zone. The pipeline would cross Capri Creek using a jack and bore construction method to avoid impacts to the creek and aquatic habitat. Pits would be set back approximately 40 feet from the top of bank. The pipeline would cross Corona Creek either by being hung off the existing bridge or by using a jack and bore construction method with the pits being placed in the street. This pipeline alignment would allow use of recycled water for irrigation at Kenilworth Junior High School, Corona Elementary School, Sonoma Mountain Elementary School, Santa Rosa Junior College, Eagle Park, Leghorn Park, Fox Hollow Park, G &G Supermarket, and five LADs (Mountain Valley, Cader Farms, Cader Farms Highlands, Kingsmill, and Landsdown). The extension of the recycled water line south of Lakeville Highway is shown in Figure 4, Oakmead Pipeline Alignment. This pipeline route would use only public right -of -way within the City -owned streets Cypress Drive and Pineview Way. The construction zone would be limited to the street with some disturbance of the adjacent landscaped area. This pipeline alignment would allow use of recycled water for irrigation at the existing landscaped areas adjacent to the alignment within the Oakmead Business Park. Construction Schedule Construction of the Oakmead Recycled Water Line would begin in summer 2016 and be completed within approximately two months. Construction of the Sonoma Mountain Recycled Water Line is expected to begin in spring 2017 and be completed in about four months. Connections of the existing irrigation systems to the new recycled water pipelines would occur shortly after completion of the pipeline construction. Other Required Agency Approvals Following is a list of potentially applicable permits and approvals from state and local responsible agencies under CEQA. These agencies may need to issue approvals for the project and, thus, may need to rely upon this CEQA Checklist and the WREP EIR. Caltrans 2016 Urban Recycled Water System Expansion Project — CEQA Checklist 3 11 Any work performed within Caltrans right -of -way at Lakeville Highway would require an Encroachment Permit. State Water Resources Control Board The City may apply for Proposition 1 funding from the State Water Resources Control Board. Also, the project may need to comply with the General Construction Activity Stormwater NPDES permit requiring preparation of a Stormwater Pollution Prevention Plan. An engineer's report on the manner by which the recycled water program will comply with the Water Recycling Criteria contained in the California Code of Regulations Title 22, must be submitted to the Division of Drinking Water at the State Board. California Department of Fish and Wildlife A Streambed Alteration Agreement, pursuant to Section 1602 of the state Fish and Game Code, may be required for the pipeline crossings of Capri and Corona creeks. 2016 Urban Recycled Water System Expansion Project— CEQA Checklist 4 12 r +3 /V L.'e,(d 10713 1-.

Minor updates and edits have been made to the Project Measures and Mitigation Measures to make them consistent with changes to regulations and the specific project evaluated in this document; none of these changes reduces the effectiveness of the measures. Program Implementation and Monitoring The City of Petaluma shall be responsible for overall implementation and administration of the Mitigation Monitoring and Reporting Program. The City may partner with others, such as recycled 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 EIR. The Coordinator will also ensure that the mitigation measures are completed in a timely manner. Duties of the Coordinator include the following: • Coordinate with applicable agencies that have mitigation monitoring and reporting responsibility; • Coordinate activities with the construction manager; • Coordinate activities of all in -field monitors; • Develop work plan and schedule for monitoring activities; • Coordination of activities of consultants hired by the City when such expertise and qualifications are necessary; • Routine inspections and reporting activities; • Plan checks; • Assure follow -up and response to citizen inquiries and complaints; • Maintain the Mitigation Monitoring Checklist or other suitable mitigation compliance summary; and • Coordinate and assure implementation of corrective actions or enforcement measures, as needed. 2016 Urban Recycled Water System Expansion Project —CEQA Checklist 9 17 Measures Included in the Project PD -2 Revegetate Temporarily Disturbed Sites The City shall revegetate sites disturbed or scarred by construction activities. Revegetation of disturbed sites should occur prior to the start of the rainy season. The Revegetation Program shall include the following: Upland Non -Urban Sites • Restore pre - project topographic features. In those cases where full restoration is not possible, graded contours shall be rounded to emulate the natural landforms of the adjacent area. • Use drought - tolerant native plant species. • Collect seed material of woody and herbaceous plants from the construction corridor and /or adjacent undisturbed vegetation during a suitable season for each group of plants. Use potted plant materials to replace woody vegetation (i.e., trees and shrubs). • Apply dried seed material collected as specified earlier evenly to the finish - graded topsoil surface. Urban Sites • Restore pre - project topographic features. In those cases where full restoration is not possible, graded contours shall be rounded to emulate the natural landforms of the adjacent area. • Use species comparable to those removed from the disturbed area or use native, drought resistant species, if possible. Topsoil • The first six inches of topsoil shall be stripped from areas to be occupied by structures, and areas to be excavated, graded, or filled. The stripped topsoil shall be stockpiled on -site, in designated areas and not mixed with other soils. Topsoil shall be stockpiled free from vegetation, trash, large stones, and other extraneous materials, to the extent possible. Stockpiled topsoil shall be protected from disturbance, rainfall, and erosion until it can be placed as final grade or otherwise reused. Planting Density and Survival Rate • A survey shall be conducted to identify plant types and locations prior to the start of construction. Plants shall be installed, maintained, and replaced such that 120 percent of the original plant density is present on the five -year anniversary of plant installation. Monitoring • Plant survival shall be monitored and summarized in an annual report. Annual reports shall include recommendations to be implemented to remediate the previous year's failures including replacement planting. Alignment Applicability: Sonoma Mountain Alignment only Implementing Agency: City of Petaluma, Construction Manager 2016 Urban Recycled Water System Expansion Project— CEQA Checklist 10 18 Timing: Start: Prior to Final Completion Complete: Revegetation will be completed before completion of construction.

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. Alignment Applicability: Sonoma Mountain and Oakmead Business Park Alignments Implementing Agency: City of Petaluma Timing: Start: Design measures — During component design. Construction measures — At the start of construction. Complete: Construction measures — at completion of construction. If a compensatory program is implemented, then monitoring will commence for five years after construction. Monitoring Agency: City of Petaluma 2016 Urban Recycled Water System Expansion Project— CEQA Checklist 33 41 Validation: Report that 90% plans conform with measure. Mitigation projects shall be monitored annually for five years using success criteria developed by the City. 2016 Urban Recycled Water System Expansion Project— CEQA Checklist 34 42 CR -1b Identify and Avoid or Minimize Impacts to Cultural Resources 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 (SHOO), 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 relevant regulatory agencies; • Consulting with regulatory agencies and associated communities to ensure the appropriate treatment of any Traditional Cultural Properties which may be impacted by the project; and • Monitoring culturally sensitive areas.

The proposed buried Register of Historic Places? pipelines would not adversely affect the historic nature of the Ranch. Also, recycled water irrigation is proposed at Fox Hollow Park which is located on or near an archaeological site (P -148). However, irrigation pipelines are already in place at the Park, and therefore, no construction would occurwithin the known boundaries of the archaeological site. Irrigation with recycled water instead of potable water would not have significant impacts on the resource. There is the potential for buried or otherwise undiscovered historical and archaeological resources to be present in the construction area. If encountered during construction, this would be a significant impact. Mitigation Measure CR -1b, Identify and Avoid or Minimize Impacts to Cultural Resources, would reduce potential impacts to less than significant. 2616 Urban Recycled Water System Expansion Project- CEQA Checklist 58 66 Significance Thresholds Project Impact Discussion Program Level of Project Level of Mitigation Significance Significance Measure CR -2.
