DISCUSSION The Santa Ana Delhi Diversion Project (Delhi Project) is a regional collaboration between Santa Ana, Costa Mesa, Newport Beach, County of Orange, and the Orange County Flood Control District. The goal of the Delhi Project is to improve the water quality in Newport Bay and increase regional groundwater supplies. Completion of the Delhi Project will also help Santa Ana meet federal storm water program requirements mandated by the California State Water Resources Control Board. 20B-1 Cooperative Agreement with the City of Costa Mesa Santa Ana Delhi Diversion April 19, 2016 Page 2 The Delhi Project will divert trash and debris flow from the Santa Ana Delhi Channel into a containment area while conveying dry weather flows into an Orange County Sanitation District (OCSD) trunk sewer main. The OCSD trunk sewer main serves an Orange County Water District (OCWD) advanced water purification system ("Groundwater Replenishment System") which helps replenish OCWD aquifers benefitting the public. OCWD participation in the project will assist in accomplishing its goal to increase flows in the OCSD system and increase source water for groundwater replenishment. In accordance with Section 15074(b) of the California Environmental Quality Act (CEQA), before any action can be taken on a project, the decision -making body of the lead agency must first consider the environmental impacts of the project. Since the City of Santa Ana is the lead agency for the Delhi Project, Council approval of the environmental impact findings is required. A Mitigated Negative Declaration has been prepared for this project (Exhibit 1). The process is summarized in the Environmental Impact section below. The City of Costa Mesa is currently advertising for bids to construct its Bristol Street Median Project within the City of Costa Mesa. The project is scheduled to start in May 2016. However, a portion of the Delhi Project is within the city limits of Costa Mesa and will conflict with the Bristol Street Median Project. The Delhi Project is several months away from advertising and is not scheduled to start until early 2017. To mitigate this conflict, staff recommends building the underground portion of the Delhi Project in conjunction with Costa Mesa's Bristol Street Median Project. By including this work in Costa Mesa's project, the Delhi Project (and, by extension, the City of Santa Ana) will experience significant savings in construction management costs, mobilization costs, street reconstructions costs, traffic control costs, as well as construction time savings. To realize these cost savings and to allow Costa Mesa to complete their time -sensitive, grant - funded Bristol Street Median Project, the City of Santa Ana and the City of Costa Mesa desire to enter into a Cooperative Agreement (Exhibit 2). This agreement outlines a funding exchange in which Santa Ana will provide funds to Costa Mesa, in an amount not to exceed $1,100,000. These funds are to be used exclusively to construct the portion of the Santa Ana Delhi Diversion Project that is in conflict with the Costa Mesa Bristol Street Median Project. The advance is comprised of the City of Santa Ana's share of the construction cost for the Delhi portion ($500,000) and the City of Costa Mesa's share ($600,000). The Cooperative Agreement requires Costa Mesa to reimburse Santa Ana for its $600,000 share by January 31, 2017. The City of Santa Ana's Capital Improvement Program for Fiscal Year 2015-2016 currently identifies a total budget of $343,050 for Preliminary Engineering expenditures. The budget increase of $1,100,000 is needed to fund the cost to construct the portion of the Santa Ana Delhi Diversion Project that will be completed along with the Costa Mesa Bristol Street Median Project. Approval of the appropriation adjustment will allocate the necessary funds for the completion of this portion of the project. 20B-2 Cooperative Agreement with the City of Costa Mesa Santa Ana Delhi Diversion April 19, 2016 Page 3 A separate Cooperative Agreement will establish funding obligations for all agencies participating in the Delhi Project. It is anticipated that the Delhi Project Cooperative Agreement will be finalized and approved by all parties involved in June 2016. Expenditures for the portion of the Delhi Project constructed in Costa Mesa will be credited toward Santa Ana and Costa Mesa's respective future obligations. STRATEGIC PLAN ALIGNMENT Approval of this item supports the City's efforts to meet Goal #6 Community Facilities & Infrastructure, Objective #1 (establish and maintain a Community Investment Plan for all City assets), Strategy G (develop and implement the City's Capital Improvement Program in coordination with the Community Investment and Deferred Maintenance Plans). ENVIRONMENTAL IMPACT In accordance with the California Environmental Quality Act (CEQA), a Mitigated Negative Declaration (MIND) has been prepared for the Santa Ana Delhi Channel Diversion Project (Exhibit 2). As noticed in the Orange County Register on January 27, 2016, the public review period for the MND was from January 27, 2016, to February 25, 2016. Documentation was available for viewing on the City website, the Public Works Counter in City Hall, the Santa Ana Main Library, and the Orange County Public Library, Mesa Verde Branch. Written comments on the MIND were received from Orange County Public Works, Department of Transportation (Caltrans), Orange County Water District, John Wayne Airport, and the Santa Ana Regional Water Quality Control Board. The comments did not present issues that were substantive in nature or resulted in changes to any MIND findings. All comments have been addressed in the Response to Comments document on the MIND. The proposed project would have a less than significant impact on the environment. As planned, the Delhi Project would eliminate dry weather flows in the Santa Ana Delhi Channel to help improve water quality in downstream receiving waters including Upper Newport Bay. FISCAL IMPACT With the approval of the appropriation adjustment, revenues in the amount of $1,100,000 will be recognized in the Federal Clean Water Protection Enterprise Fund as follows: $600,000 in the Expense Reimbursement from City of Costa Mesa account (No. 05717002-57013) and $500,000 in the Prior Year Fund Balance account (No. 05717002-50001) for appropriation into the Federal Clean Water Protection Enterprise Fund Capital account (No. 05717640-66220) for expenditure in Fiscal Year 2015/2016. The reimbursement in the amount of $600,000 from the City of Costa Mesa will be received in FY 2016-2017. r1- Cooperative Agreement with the City of Costa Mesa Santa Ana Delhi Diversion April 19, 2016 Page 4 APPROVED AS TO FUNDS & ACCOUNTS: Are"MousAvipour Francisco Gutierrez Executive Director Executive Director Public Works Agency Finance & Management Services Agency FM/EW G/TC Exhibits: 1.

The Project is intended to remove dry -weather channel flows from the Santa Ana Delhi Channel watershed and divert said flows into the Orange County Sanitation District's regional collection system for treatment prior to discharge into the ocean or to be utilized as source water for the regional Ground Water Recharge System. The primary intent of the Project is to protect Upper Newport Back Bay from additional pollutant loading generated by flows from the Santa Ana Delhi Channel watershed. The proposed Project consists of three major components: 1) dry -weather diversion; 2) floatable debris removal system; and 3) pumping facilities to the regional sewer collection system. The Project also includes a 1.6 mile pipeline in Bristol Street to the regional sewer in Baker Street in the City of Costa Mesa. The proposed Project will be located within the Newport Beach Golf Course, adjacent to the east side Aerial Overview Santa Ana Delhi Diversion Project Location of the Santa Ana Delhi Channel approximately 900 feet upstream of the Irvine Avenue. The Project is being developed with cooperation between the Cities of Santa Ana, Newport Beach, and Costa Mesa, Orange County Public Works (OCPW) and the Orange County Flood Control District (OCFCD) (Project Stakeholders). The Project is viewed as a multi -functional benefit and regional water quality improvement project associated with the current and future NPDES requirements and specifically in accordance with the proposed trash amendment to the existing Municipal Separate Storm Sewer System (MS4) permit requirements. The IS/MND concluded that construction and operation of the Project would not result in significant adverse impacts to the environment. In accordance with the CEQA Guidelines, the IS/MND was circulated for public and agency review for a period of 30 days. This review period began on January 27, 2016 and ended on February 25, 2016. Public notice of availability was published in the Orange County Register on January 27, 2016. The Notice of Availability was also provided to the Orange County Clerk's office. The IS/MND was available for review at: • City of Santa Ana Public Works Counter • City of Santa Ana Public Library • Orange County Public Library — Mesa Verde Branch (in Costa Mesa) • City of Santa Ana Public Works Agency website: http://www.ei.santa-ana.ca.us/pwa/ 20B-7 The IS/MND was sent to the State Clearinghouse (SCH) for distribution to state agencies and was assigned SCH # 2016011069.

IF 2.0 RESPONSE TO COMMENTS 2.1 COMMENTS FROM ORANGE COUNTY PUBLIC WORKS (FLOOD PROGRAMS ENVIRONMENTAL RESOURCES, AND TRAILS) - FEBRUARY 24, 2016 2.1.1 Flood Programs 1. Comment: Request the IS/MND consistently address the County/ OCFCD as one of project proponents along with the Cities of Santa Ana, Newport Beach and Costa Mesa. Response: Comment noted. All references to the Project Proponents should include County/OCFCD. 2. Comment: Change reference to Watershed Protection Group in Section 1.0 to Environmental Resources. Response: Comment noted. The name change is acknowledged. 3. Comment: Correct typo, reference are listed in Section 6.0, not 7.0. Response: Comment noted. 4. Comment: Please verify acreage of Santa Ana Delhi Channel (F01) catchment area. Response: OCFCD provided a new watershed drainage area map that shows a FO1 watershed area of 10,900 acres. This new map is provided as Attachment B of this Response to Comment document. 5. Comment: Please verify drainage boundaries of Santa Ana Delhi (F01), Santa Ana Gardens (F02) and Paularino (F03) shown in the Figure 1 of the 1YIND versus the FOI Proposed Diversion Structure Watersheds map provided by the OCFCD to the City of Santa Ana. Response: OCFCD provided a new watershed drainage area map showing boundaries for FOl, F02 and F03. This newer map is included as Attachment B and would supersede Figure 1 in the IS/MND. 6. Comment: Based on the new drainage area map provided, please verify the contributory acreages of the Cities of Santa Ana, Costa Mesa, Newport Beach, Irvine and Unincorporated Orange County. Response: Based on the new drainage area map provided by OCFCD, the contributory acreages of the Cities of Santa Ana, Costa Mesa, Newport Beach, Irvine and Unincorporated Orange County are: 6983, 3019, 128, 159 and 611 acres, respectively. 7. Comment: The proposed diversion should not worsen existing hydraulic conditions of FOI. Existing and post project hydraulic analysis need to be performed to evaluate the project's impact to FOI and mitigation measures proposed in consultation with OCPW if there are any adverse impacts. Response: The project is designed in accordance with the OC Flood Design Manual to meet all requirements for maintaining the flood control capacity of the channel. Hydraulic analyses have been performed by URS in coordination with OCFCD and provided in the Hydraulic r14• Study on file with OCFCD. The Hydraulic Study describes the analyses performed on the channel, diversion structure, and local storm drain inlet systems. The level of flood protection offered by FO1 has not been affected. No additional flood areas have been created by the proposed structure. S. Comment: The description of Element 2 (Debris Containment System) specifies what happens to flows/debris up to 2 feet in depth and flows/debris above 3 feet in depth but under 7 feet. Provide an explanation of what happens to floating debris and flows within the range of 2-3 feet of depth. Response: At no point are flows fully retained by the diversion structure. For clarification, the following description of operational flow ranges is provided. All flows less than 20 cubic feet per second (cfs) will be redirected into the facility by the cross -channel weir to be treated via an inclined (Coanda) screen and returned to channel through a transfer culvert within the off -channel diversion facility (HEC-RAS Bypass Culvert). Flows exceeding 20 cfs will exceed the flow capacity of the transfer culvert and begin to flood the off -channel diversion facility and pass through trash nets for floating debris treatment until a point such that sufficient downstream head has been built to overtop the cross channel weir. At this point, flows and floating debris will be skimmed by the resting reinforced boom into the off -channel diversion facility until a channel water surface of approximately 18 inches has been reached. Once a water surface of 18 inches has been reached, the boom will begin to float up to a water surface of 6 feet 6 inches (approximately a 2-year water quality event). The boom will slum and redirect the top portion of flows for floating debris into the off channel diversion facility up until this set release point has been reached. After a water quality event water surface has been attained, the boom will release from the downstream support while remaining fixed to the upstream support. Floating litter and debris directed into the off -channel diversion facility will be retained by the trash nets. Concurrently, the trash nets will collapse after a water quality event water surface has been attained in order to prevent damage from the 100-year flood control event water velocities. A secondary coarse bar screen has been provided at the exit of the off -channel diversion facility to retain pollutants that have entered the off -channel diversion facility but have either bypassed the trash nets or exceeded the trash net storage capacity during a water quality event. 9. Comment: Please verify maintenance frequencies described in different sections of the IS/MND for consistency. Response: Long term maintenance, which includes removal of accumulated debris, sediment, and floatables within the diversion facility, is expected to be on a 30-day maintenance cycle, after each rain event, or as required. 10. Comment: Please state in the IS/MND and Operations & Maintenance Plan detailing all required maintenance activities, responsibilities, and the frequencies associated with all three project elements. All permits including those from Regulatory Agencies should be shared with the OCFCD/County before they are finalized and become part of the O&M Plan. 205--10 Response: Operation and maintenance activities, responsibilities and frequencies of each project element are identified in the table below. The Project Stakeholders named in the Memorandum of Understanding (MOU) that is currently under development will be responsible for ensuring that all stakeholders are informed of the regulatory permit process and provided an opportunity for review/comment as applicable.

Comment: The access road has to be moved within the golf course in a manner that does not impact operation of the golf course. Response: During project construction, the access road will be temporarily closed off, but the bridge over the channel to the Front Nine will remain open. Long-term, the project has been designed so that the re -aligned portion of the access road will be outside the golf course existing lines of play. 12. Comment: Please add text regarding the project footprint requirements of the pipeline and other features outside the County R/W as appropriate. Response: The pipeline will be L6 miles long and placed in a 5-foot wide trench in the existing paved Bristol Street right-of-way. Pipeline construction plans will be reviewed and approved by the City of Costa Mesa. 13. Comment: The existing access road is not open for public use at this time. Please revise text as appropriate. Response: It has been confirmed by Jeff Dickman of OCPW that the existing access road is part of the Santa Ana Heights Regional Riding and Hiking Trail, a county master -planned trail, and open for public use. The purpose for the trail is to connect the equestrian stable at the OC Fairgrounds to Upper Newport Bay and to two other regional routes leading to Peters 20B-11 Canyon Regional Part, Mason Regional Park and Irvine Coast Wilderness Park. Trail users include walkers, joggers, runners, hers, mountain bicyclists and equestrians. 14. Comment: Suggest labeling the "Back and Front of the Ninth hole" and the pedestrian bridge on Figures 5 and 6 for anyone not familiar with golf terminology. Response: Figures 5 and 6 have been revised to include labels for these features, and are included as Attachment C of this Response to Comments document. The `Back Nine" is the Newport Beach Golf Course's official name for the South East portion of the course which contains the reservoir (take). The "Front Nine" is the official name for the North West portion of the course. The two halves are separated by the Santa Ana Delhi Channel which has a pedestrian bridge spanning the two halves of the full course. 15. Comment: Page 2-17, first paragraph reference the public recreation trail. Please delete all references to trails in the IS/MND. Response: See Response to Comment 13. 16. Comment: As shown in Table 2.4-1 (page 2-18 of the IS/MND), please identify where the 13,380 sq. ft. permanent maintenance easement and 4,300 sq. ft. sewer easement will be located (e.g. within the streets, JWA or County property?). Response: Easements will be within the Newport Beach Golf Course as shown in Figures 5 and 6 (Attachment C). 17. Comment: Page 3-1, under item No. 5 Project Sponsor, please clarify here and throughout the IS/MND that OCFCD is a Project Sponsor. Response: Comment noted. It is acknowledged that OCFCD is a Project Sponsor along with the Cities of Santa Ana, Newport Beach and Costa Mesa. Section 3.1 has been revised to list OCFCD as a Project Sponsor and included in Attachment D of this Response to Comments document. 18. Comment: It should be shown with analysis that the proposed in -channel diversion facility and appurtenances will not affect the existing flood protection level provided by the flood control facility. Response: See Response to Comment #7. The project will not affect the existing flood protection level provided by the flood control facility. 19. Comment: Please confirm the submerged depth of the pumps so that the IS/NIND and the project plans are consistent. Response: The pump station wet well has a bottom invert of 32 feet below grade. During normal dry weather operation, sump pumps shall be submerged between 2 and 8 feet of water depth during pump cycling. During wet weather operation, wet well water surface will be equal to channel water surface. 20. Comment: Agreements between the OCFCD/County and project partners are required in order to define the terms and conditions under with OCFCD/County will accept modifications to the channel and/or accept/share right-of-way, maintenance 209-12 responsibilities and associated costs before construction starts and permits can be issued for work within OCFCD/County right -of way. Response: Comment noted. Project Stakeholders are currently developing a MOU for project operation and maintenance activities. 21. Comment: Please add the Preliminary Design Report including supporting technical report(s) under "Appendices" on page ii of the IS/MND. Response: Comment noted. It is acknowledged that the Preliminary Design Report could have been included as a technical appendix to the IS/MND. However, the Preliminary Design Report has been modified as part of final design and therefore some of the design portions of the report are no longer current. 2.1.2 Environmental Resources Division 1. Comment: Reference to OCPW Watershed Protection Group in Section 1.0 should be changed to OCPW Environmental Resources Division. Response: Comment noted. 2. Comment: In Section 2.4.2, Project Operations, the storm season is defined as October 16 — April 14 and the non -storm season as April 15 through October 15. To be consistent with the maintenance schedule under the County's local municipal storm water permit and related municipal/industrial and construction site inspections and maintenance that are to be conducted during the storm and non -storm seasons, the timeframes should be defined as October 1 to April 30 and May 1 to September 30 respectively. Response: Comment noted. The Proj ect's operation and maintenance schedule will be redefined in accordance with the County's local municipal storm water permit program's definitions for the storm and non -storm season. This will be October 1 to April 30 for the storm season and May 1 to September 30 for the non -storm season. 2.1.3 Comments from OCFCD/SAR/Trails 1. Comment: Over 15 years ago, the County of Orange built a portion of the Santa Ana Heights Regional Riding and Hiking Trail, a county master planned dirt trail. The trail is currently open along the east side of the channel from Irvine Avenue upstream to Santa Ana Avenue. The trail is open from sunrise to sunset for use by walkers, joggers, runners, bicycle riders and equestrians. • The proposed project must not interfere with the public's use of this trail or alter the existing decompose granite trail tread, which is the hallmark of the County/s natural —surface trails • Any alteration, detour, temporary closure or reconstruction of the Santa Ana Height Regional Riding and Hiking Trail must be approved in writing by the County prior to the start of work. • Applicant will be responsible for any repairs to the decomposed trail tread, signage, bollards, gates and other trail -related amenities. 20B-13 Response: Comment noted. The project will require temporary closure of the trail during construction of the channel diversion facilities for approximately 120 days. After construction, the trail will be restored to existing conditions using decomposed granite. The City of Santa Ana will seek approval of the trail reconstruction plans from OCPW prior to the start of work. 2.2 COMMENTS FROM SANTA ANA REGIONAL WATER QUALITY CONTROL BOARD — FEBRUARY 25, 2016 1. Comment: The Project design should consider the impacts of removing all low flows at the diversion structure to downstream aquatic ecosystems, including a freshwater emergent wetland that exists in the section of the Santa Ana -Delhi Channel downstream of the Mesa Street ,Bridge. In this location, freshwater pools form above the tidal influence that wildlife utilizes. Species observed in this location include western pond turtle and California least tern, a California species of special concern and federally - listed endangered species, respectively. As such, Project proponents should determine avoidance, minimization or mitigation resulting from Project impacts to the listed and other freshwater marsh species established in the areas downstream of the project site. United States Fish and Wildlife Service staff expressed concern over the reduction of channel flows into Upper Newport Bay that would result from the project and possible impact to the salt -water marsh located downstream of the channel confluence with the Bay. The Project proponents should respond to the USFWS concern prior to implementing the Project and consider Project options to avoid potential adverse impacts to the downstream salt marsh. Response: Portions of Final Design for the Project were based off of recommendations made by the Santa Ana Regional Water Quality Control Board in the Santa Ana Delhi Channel Watershed Water Quality Surrnnary (Shibbeiu, 2009). This summary recommended that the channel low -flow notch be blocked during the dry season (See Table 16 of Section 5.0). Final Design of the project included blocking the trapezoidal low -flow "notch" during all weather events via a cross -channel weir. Up to 20 cubic feet per second (efs) of flows blocked by the proposed diversion structure will be screened via an inclined screen (Coanda) type BMP to remove trash and debris. Up to 3 cfs may be pumped from a Transfer (Bypass) Culvert to be discharged into the regional sewer collection system; all flows exceeding this capacity will be returned to channel. The Bypass Culvert is designed such that up to 20 cfs of annual flows will be returned to channel after receiving screening treatment to remove trash and other debris. Also, flows in the channel downstream of the Project (e.g. below the Mesa Street Bridge) will not be affected by the Project and will continue to flow in this downstream charnel reach. These flows enter the channel from local storm drain inlets that include at least (1) 36", (2) 42", and (3) 18" storm drain system inlets and contribute to channel flows downstream of the Proj ect. To address USFWS' concern regarding reduction of channel flows into Upper Newport Bay, operation of the Project pumps to divert flows to the regional sewer collection system (Element 3) could be modified, including pumping for a shorter duration, or if necessary shutting down the pumps at certain times to provide low flows that the USFWS and the SARWQCB find agreeable for discharge into the Upper Newport Bay. 2. Comment: Project implementation could result in increased erosion in the earthen downstream sections of the channel. The project would remove sediment from dry weather flows along the earthen section of the channel from Mesa Street to Upper Newport Bay. The lack of sediment deposition could encourage greater scouring during wet weather flows. Board recommends conducting a hydraulic study of the channel examining sediment transport prior to determining whether to construct the project. Response: OCFCD is currently aware of erosion issues along the earthen section of the channel from Mesa Street to Upper Newport Bay and is currently developing a channel restoration project to address these issues. Erosion issues result from upstream portions of the channel that are fully hardened in a fully urbanized watershed with comparatively minor sediment loading from the Delhi Watershed to Newport Bay Watershed (Shibberu, 2009). It is estimated that of the 74.7 tons of combined material removed annually from Santa Ana Delhi sub -watershed based on period 2012-2014 (OCFCD), 33.3% consisted of sediment which amounts to 24.6 tons of sediment. It is possible that 24.6 tons of sediment may be fully retained by the proposed diversion structure and removed by maintenance operations. This retained 24.6 tons of sediment constitutes 0.04% of the overall TMDL limit of 62,500 ton per annum for the Newport Bay Watershed (Shibberu, 2009) and would not require a hydraulic study of the channel examining sediment transport. During wet weather, water is not capable of pooling several feet deep behind the diversion structure before it is released downstream. Flows less than 20 cfs will be diverted through an off -channel diversion facility for screening treatment and returned to channel via a Bypass Culvert. Flows exceeding 20 cfs, but less than that of a 2-year water surface will pass through both the off -channel diversion facility trash nets, and main channel. Only the top 18 inches of flows are to be skimmed for floating litter and debris by a floating boom that rises to match the 2-year water surface. The boom will partially release after a 2-year water surface has been reached to maintain the 100-yearflood control capacity of the channel provided by both the off -channel diversion facility and the main channel at the proposed project site. At no point are flows fully contained by the facility, only 3 cfs of dry -weather flows may be pumped from the Bypass Culvert if not returned to channel. 2.3 COMMENTS FROM ORANGE COUNTY WATER DISTRICT (OCWD) — FEBRUARY 25, 2016 1. Comment: OCWD operates a non -potable recycled water supply system called the Green Acres Project that delivers recycled water to irrigation and industrial users. A portion of the Green Acres Project pipeline is located in the vicinity of the proposed Santa Ana Delhi Channel Diversion Project area. OCWD requests that the applicant consider potential impacts to this pipeline as the project is designed and constructed. Response: Comment noted. Project design plans include provisions for maintaining clearance of the Green Acres Project pipeline. 20B-15 2.4 COMMENTS FROM JOHN WAYNE AIRPORT (JWA) - FEBRUARY 25, 2016 1. Comment: Homes border the golf course that could be impacted by excessive odors as well as people who play golf along the channel. The MND should include a clear description of how odor issue will be mitigated or eliminated. Response: IS/MND Section 4.3.1.e (page 4-15) addresses potential odor impacts of the project. The section states that the screening of trash may result in the build-up of trash which may be a source of odors. Removal of accumulated trash within the channel is expected to be on a 30-day maintenance cycle, after each rain event, or as required. If collected trash presents a source of odors, the atypical source of trash would be removed or the frequency of cleaning would be increased to eliminate the source of odors. 2. Comment: JWA appreciates that project maintenance language provided in the MND allows for more frequent clean -out of the diversion facility as needed. Response: Comment noted. 3. Comment: JWA requests that the HIND discuss whether any trees will be impacted by the project and recommends that the trees be saved if possible, or that other trees be replanted. Response: Existing non-native trees along the fence line of the golf course will be removed to accommodate the relocated access road. Replacement of trees, if desired, can be addressed in the MOU being prepared by the Project Stakeholders. 4. Comment: In several MND sections, there is reference to "County of Orange Airport Land Use Commission." This should be changed to "County of Orange/John Wayne Airport", since County of Orange/John Wayne is the property owner with authority to grant easements for the project, not the Commission. Response: Comment noted. 2.5 COMMENTS FROM DEPARTMENT OF TRANSPORTATION (CALTRANS) -FEBRUARY 23, 2016 1. Comment: Caltrans requests that the applicant submit Environmental Review Documents to the Local Development/Intergovernmental Review Branch prior to request for permit. Response: On January 26, 2016, URS submitted a hard copy of the IS/MND to Caltrans District 12 in advance of the Encroachment Permit application. Staff in Caltrans District 12 Environmental Unit received this copy of the IS/MND as well as relevant portions of the Project plans for review (e-mail exchange with Ed Dolan, Caltrans Environmental Unit, 02/20/16).

These acreages differ from those reported on page 2-1, Section 2.2, 2nd paragraph of the IS/MND. Please verify and revise as appropriate. 7. Page 2-7, Section 2.4.1 indicates that the proposed project includes an in -channel diversion structure that will utilize a semi -rigid floatable boon and a one foot high broad crested weir that spans the entire channel. The proposed diversion facility should not worsen existing hydraulic conditions of F01. Existing and post project hydraulic analyses need to be performed to evaluate the proposed project's impact to F01 and mitigation measures proposed in consultations with OC Public Works/Infrastructure Programs/Flood Program Support (FPS), if there are any adverse impacts. 8. Page 2-8, Element 2, 20d paragraph states, "Primary containment will be the storage location of debris and trash collected by the system for channel dry weather flows and flows up to 2 feet of depth" and "Floating debris carried by storm evets greater than 3 feet of depth but under 7 feet of depth will be redirected into the facility by Element 1 and retained by secondary containment chamber." It is unclear what happens to floating debris and flows within the range of 2-3 feet of depth. Please review and add explanation as appropriate. 9. Page 2-8, Element 2, 3`d paragraph states, "At minimum debris captured will be removed from debris storage area every 90 days. For optimum performance debris captured will be removed prior to beginning of each storm season and at conclusion of storm season." Please see also page 2-10: Storm Season Operations and Estimated Trash Removal Operation; page 2-19: Long Term Maintenance Operations; and page 4-3, 2"d paragraph.

Please state in the IS/MND that an Operations & Maintenance Plan detailing all required maintenance activities, responsibilities, and the frequencies associated with all three project elements: in -channel diversion structure, channel debris removal system, pumping facilities will be prepared. All permits including those from Regulatory Agencies should be shared with OCFCD/County before they are finalized and become part of the 0&M Plan. 11. Page 2-10, General Maintenance Operations, the IS/MND states, "However in special circumstances, such as pump removal for replacement, temporary access may be required." The access road has to be moved within the golf course in a manner that does not impact operation of the golf course. 12. Page 2-10, Section 2.4.3, Project Footprint Requirements: This paragraph seems to address the diversion footprint of the project only. It does not discuss the project related to the pipeline and other features outside of County R/W. Please review and add text as appropriate. 13. Page 2-10, Section 2.4.3 states, "The existing access road, currently open for public recreational purposes, will need to be re-established as part of the development of the project." The existing access road is not open for public use at this time. Please revise the text as appropriate. 300 N. Flower Street, Santa Ana, CA 92703 P.O.

JN. _..... � MAIT"k R rer Review of California Environmental Quality Act Mitigated Negative Declaration: Ana -Delhi Channel Diversion Project Dear Mr. Chesanek: Thank you for the opportunity to comment on the mitigated negative declaration (M ' D) for the proposed Santa Ana Delhi Diversion Project (Project). The stated purpose o the Project is to eliminate dry weather flow and floating debris in the Santa Ana -Delhi Channel to help improve water quality in Upper Newport Bay. The City proposes to construct in an unincorporated area of Orange County a dry weather diversion stru ture within the Santa Ana Delhi Channel adjacent the Newport Beach Golf Course. Whe operating, the Project will remove dry weather flows, trash, debris, and low flows du ing the wet season up to 3.0 cubic feet per second. In addition, the Project proposes th construction of a 1.6 miles long pipeline to carry the diverted flows to an Orange Co jnty Sanitation District regional collection system located on Baker Street in the City of C ost Mesa. The MND states that the City of Santa Ana, in association with the Cities of Newpc Beach and Costa Mesa, has proposed the diversion project to address surface wa quality issues. The Cities propose to address water quality issues in accordance v the Orange County Municipal Separate Storm Sewer System permit as well as the several total maximum daily loads (TMDLs) developed for Upper Newport Bay. A primary intent of the Project is to address the current selenium TMDL while also addressing TMDLs for bacteria, toxics, metals, and nutrients, and the recently app statewide trash amendment. Regional Board staff appreciates that this Project appears likely to improve water in Upper and Lower Newport Bay by reducing the loading of pollutants to the Bay. requests consideration of the following comments on the MND when designing, constructing, and implementing this Project. 1. The Project design should consider the impacts of removing all low flows at he diversion structure to downstream aquatic ecosystems. As described in the 993 draft Environmental Impact Report (EIR) #527 "Santa Ana -Delhi System", a d Santa Ana Delhi Diversion Project - 2 - February 25, 2016 easily observed when on -site, a freshwater emergent wetland exists in the section of the Santa Ana -Delhi Channel (channel) downstream of the Mesa Street Bridge and the proposed Project site. In this location, fresh water pools form above the tidal influence that wildlife utilizes. California Department of Fish and Wildlife species of special concern and Federal Endangered Species Act listed species have been reported utilizing the freshwater marsh. The United States Geologic Survey biological survey team and others have periodically identified western pond turtle (Actinemys marmorata pallida), a California Department of Fish and Wildlife species of special concern, in this section of the channel. The California least tern (Stemula antillarum brown), federally listed as endangered, feeds in the freshwater sections of the channel as reported in the 1993 EIR and by local wildlife experts. As such, the Project proponents should determine avoidance, minimization or mitigation resulting from Project impacts to the listed and other freshwater marsh species established in the areas downstream of the Project site. In addition, United States Fish and Wildlife Service (USFWS) staff expressed concern° over the reduction of channel flows into Upper Newport Bay that would result from the implementation of this Project, and possible impacts to the salt- water marsh located downstream of the channel confluence with the Bay. Recently, USFWS staff provided Regional Board staff with a documene that describes the benefits of adequate nutrients to a healthy salt -water marsh. The Project proponents should respond to USFWS' concern prior to implementing the Project, and consider Project options to avoid potential adverse impacts to the downstream salt marsh. 2. The implementation of the Project could result in increased erosion in the earthen downstream sections of the channel. Implementation of the Project would remove sediment from dry weather flows along the earthen section of the channel from Mesa Street to the Bay. The lack of sediment deposition could encourage greater scouring during wet weather flows, but the MND does not discuss this possibility. Board staff recommends conducting a hydraulic study of the channel examining sediment transport prior to determining whether to construct the Project. The MND states that during wet weather, water may be allowed to pool several feet deep behind the diversion structure before it is released downstream. The Project proponents should consider the effects of these wet weather releases to the downstream sections of channel and the habitat. In addition, the Project proponents should evaluate whether allowing routine smaller releases versus Personal communication with USFWS staff Chris Medak. z Zedler, 1993, "Canopy Architecture of Natural and Planted Cord grass Marshes: Selecting Habitat Evaluation Criteria". 20B-24 Santa Ana Delhi Diversion Project - 3 - February 26, 2016 sudden releases of these flows from the diversion structure would reduce the possibility of adverse impacts. The MND stated that a Clean Water Act Section 401 Water Quality. Standards Certification (401 Certification) would likely be issued by the Regional Board for this Project. The United States Army Corps of Engineers has consistently considered the Santa, Ana Delhi Channel Waters of the United States, which will require the Project applicant to request and obtain a 401 certification prior to constructing this Project. The Project proponents must consider appropriate measures and Best Management Practices (BMPs) to incorporate into the Project to meet water quality standards. These measures and BMPs should be included in the 401 Certification applications. If you have any questions, please contact Dave Woelfel at David.woelfelO).waterboards.ca.aov or (951) 782-7960.

Water produced from the basin is the primary water supply for approximately 2.4 million residents in Orange County. OCWD operates a non -potable recycled water supply system, called the Green Acres Project. A dedicated set of pipelines delivers recycled water to irrigation and industrial users. A portion of the Green Acres Project pipeline is located in the vicinity of the proposed Santa Ana Delhi Channel Diversion Project area. Please see the attached map indicating the location of the pipeline. We request that you consider potential impacts to this pipeline as you design and build the proposed project.

John Wayne Airport (JWA) requests that the following comments be addressed: i . The initial study does not discuss the potential for odor associated with the project. There are homes that border the golf course that could be impacted by excessive odors, as well as people who play golf along the channel. The Mitigated Negative Declaration (MND) should include a clear description of how odor issues will be mitigated or eliminated. 2. The MND does include a long term maintenance schedule. Removal of accumulated debris, sediment, and floatables within the diversion facility is expected to be on a 30-day maintenance cycle, after each rain event, or as required. We appreciate that the maintenance language does allow for more frequent cleanout if needed. 3. Figure 5 of the MND shows that the project footprint is overlaying a number of trees. We request that the MND discuss whether any trees will be impacted by the proposed project. The MND states there will be no agricultural impacts and landscaping details will be determined during final design. If any trees need to be removed, we recommend that the trees be saved if possible, or that other trees be replanted. 4. The underlined language in the sections noted below should be changed from "County of Orange Airport Land Use Commission" to "County of Orange/John Wayne Airport."
