Staff reviewed the bids and requests that the Committee support staff recommendation for award to the low bidder, Ken Thompson, Inc., for $1,099,000. The Engineer's Estimate was $1,800,000. DISCUSSION: The Zone 4C Reconfiguration Project was conceived to raise the hydraulic grade line from 675 to 706 to mitigate for low pressure in three separate areas, totaling approximately 800 homes. The construction project consists of approximately 8,500 lineal feet of 8" to 12" PVC pipe, valves and other related improvements. It is anticipated that construction will be complete by December 2009. Bids were received from 19 contractors, ranging from a low of $1,099,000 to a high of $1,732,175. The bid tabulation and other bid documents from the low bidder, Ken Thompson, Inc., was reviewed by District staff and the District's attorney, and found to be acceptable. PRIOR RELEVANT BOARD ACTION(S): June 28, 2007, Board adopted Budgets for Fiscal Years 2007/08 and 2008/09 and approved the Current Five Year Capital Improvement Plan for FY 2007-2012. September 13, 2007, Board authorized staff to modify the Current Five Year Plan Capital Improvement Projects List and the Adopted Budget for Fiscal Years 2007-2009 by adding the Zone 4 Reconfiguration Project for the Twin Peaks Area of East Lake Village. March 13, 2008, Board received and filed the Zone Reconfiguration Study for Areas 1, 2 and 3 and authorized staff to solicit proposals for the design of the combined projects. May 15, 2008, Board authorized execution of a Professional Services Agreement with Psomas for a fee not to exceed $113,676 to provide design and bid services for the Zone Reconfiguration and Sub Zone Extension Projects.

I i ITEM NO. AGENDA REPORT Committee Meeting Date: February5, 2009 To: Planning-Engineering-Operations Committee From: Steve Conklin, Engineering Manager Staff Contact: Hank Samaripa, Project Engineer Reviewed by General Counsel: No Budgeted: Yes Total Budget: $ 5.5M Funding Source: Water Revenue Bond CEQA Account No: 101-2700 Job No:200814 Compliance: N/A Estimated Costs: $ 50,000 Dept: Engr. Subject: Contract for Highland Booster Station Engineering Feasibility Study SUMMARY: As part of the District's plans to maximize the full potential of its groundwater production capabilities to its service area, the District solicited proposals from several consultants for conducting an Engineering Feasibility Study to replace and expand the Highland Booster Pump Station (BPS) to eliminate deficiencies and increase flow to 18,000 gpm. Staff received four consultant proposals for the expanded booster station. Following an evaluation, staff recommends award to Tetra Tech for a fee of $45,675.00. DISCUSSION: As previously reported to the PEO Committee, the District is experiencing lower than projected flows at the Highland BPS. Currently the maximum throughput is 10,500 gpm. Initial reports indicate an undersized suction header pipeline to be the cause. The projected requirement for Zone 2, the District's largest, is 15,000 gpm with peak flow up to 18,000 gpm. With the current suction pipeline configuration this is not possible. The District solicited proposals for an engineering feasibility study to address the undersized suction header, the number of pumps, location of the suction and discharge pipeline for the increased production, and constructability while maintaining the existing Highland BPS in production.

Project Director Project Manager RSA/SES:cg M:\Marketing\Proposals\WTRS\2009\001\fiml\Olcover lm.doc Attachment YORBA LINDA WATER DISTRICT Highland Booster Station Replacement/Expansion PROJECT UNDERSTANDING Introduction The Yorba Linda Water District has solicited proposals for engineering consultants to provide a comprehensive engineering feasibility study (EFS). The EFS will determine the best approach for the Highland Booster Station Replacement/Expansion; including but not limited to, the booster pump station location and layout; number, size and type of pumps and drives (gas or electric), other site constraints (noise, power, interruption, etc.); project phasing and staging; design and construction cost estimate; and schedule for design and construction. Background The Highland Reservoir and Booster Pump Station (BPS) is located at 5252 1/2 Highland Avenue in the City of Yorba Linda The original 4.7 MG reservoir, constructed in 1910, is being replaced with a new 6.0 MG buried concrete reservoir, planned for completion in late 2010. Schuler Engineering is the District's General Contractor for the Reservoir Replacement Project. During the construction of the new reservoir the District will be operating with two temporary above-ground steel tanks. The existing BPS was upgraded in 2003 to provide a maximum flow of 15,500 gpm, with the planted replacement of two 125-hp electric motors (BOI and B02). However due to an undersized 18-inch suction header, the maximum capacity has been determined to be in the range of only10,500 gpm Existing pump information is as follows: B01 125 Vertical Turbine 2,000 gpm Electric Motor B02 + 125 Vertical Turbine 2,000 gpm Electric Motor B03 200 Vertical Turbine 3,000 gp_m Electric Motor B04 200 Vertical Turbine 3,000 gput Electric Motor B05 250 Horizontal Split Case 3,500 gpm Natural Gas Engine I _ I As part of the 2003 Highland BPS upgrade project, a 525 kW rated engine-generator was added to supplement the electrical power needs of the pump station during high demand periods and peak electric- rate periods by Southern California Edison. During its operation, the 525 kV engine-generator can operate two 200-hp electric pumps and one 125-hp electric pump. The existing Highland BPS site also has an on-site hypochlorite generation (OSHG) chlorine generation system. The OSHG is located in a building, which upon evaluation, is not being utilized 80 percent of the time. Disinfection treatment is otherwise being provided at the main Richfield Operations site and again at Lakeview Booster Station thereby rendering operation of the OSHG at Highland expendable. The Highland Reservoir and BPS is a major supply for 570 foot pressure zone 2 and the Lakeview Reservoir and Booster Station. Supply is delivered via a 30-inch CML&C steel transmission main through the main thoroughfares of the City of Yorba Linda. Access to the Highland site is from the northeast corner through the narrow north Highland Avenue, Mountain View, and eventually to Yorba Linda Boulevard. There is restrictive and limited access available from the southwest corner through Highland Avenue from Buena Vista Avenue. It is anticipated that both the new Highland reservoir and the proposed Highland Booster Station Replacement and Expansion could be in construction simultaneously thereby requiring coordination of certain activities to avoid conflicts between contractors. The EFS is to address this coordination issue. :mark.,mewooowi,twixcuoovmt~dron:.~.ao~ - 1 - TETRA TECH YORBA LINDA WATER DISTRICT Highland Booster Station Replacement/Expansion The existing booster station pad area is approximately 42 feet by 115 feet and consists of concrete-block walls with sound attenuation panels around the perimeter, and two interior block structures; one for the gas engine and other for disinfection facilities. Within the booster station pad area are the pumps and support equipment, a 1200A Main 480V 3-phase electrical service, one steel surge tank and a 24-inch epoxy-lined discharge header. The surrounding site has many large native trees, some of which will be removed from the site for the new 6.0 MG reservoir. The trees are identified in the Mitigated Negative Declaration report of June 2006 by Bonterra Environmental. The purpose of the EFS is to evaluate layout options and to determine cost-effective resolution to all issues which may surface for the replacement/expansion of the Highland BPS. The new facility will be sized to deliver 15,000 gpm on a continuous basis and 18,000 gpm of peak flow. Critical issues include maintaining operation of the existing pumps B01 through B04 during construction of the new pump station without interfering with the construction of the new 6.0 MG reservoir or the delivery of water. It is noted that Pump B05 does not have to remain in service during construction of the new BPS. It is assumed that at the completion of construction of the new BPS, all of the existing pumps and the two existing buildings can be demolished. The EFS should address the possibility of reuse of the current PLC cabinet and controls. Key Issues Successful implementation of the project will involve resolution of several key issues. We believe Tetra Tech has an unparalleled grasp of these issues based on our overall experience, capabilities and familiarity with this site, other YLWD BPSs as well as YLWD standards, personnel and policies. Our approach to resolving project issues is summarized below. Constructability Review and Phasing: The existing BPS is required to remain in service while the new BPS is constructed to provide continuous water service. Developing an acceptable layout that will allow this to occur will be of the utmost importance. Tetra Tech will develop alternatives to best allow this to occur. We have already developed some layouts that meet this requirement and included them as pact of this proposal. A written construction phasing description will be presented in the EFS. Tetra Tech will consult with Schuler Engineering, the District's reservoir contractor, to review constructability and phasing for the alternatives developed. Selection of Pump Drives: Tetra Tech will investigate pump station alternatives that will include: vertical motor driven pumps, engine driven pumps, and combination motor and engine driven pumps. Capital and operation costs will be developed and presented and a recommended alternative will be made. Economics will consider peak and off peak power costs that the District pays for its pumping of water. Pump Station Sizing and Layout: We have done some preliminary sizing and layout options for the pumping station. We took into consideration providing access around equipment for operation and maintenance as well as access into the building. Preliminary General Sizing Information r Description Number of Duty Pumps_ 3 Discharrge Line Size- 24 inch Number of Standby Pumps 1 Suction Line Size 24 inch Pump Flow Rate Max 6,000 gpm Pump Diameter 19 inch I Estimated HP to 570_Zone 400 hp _ Number of Stages e~_ 2 Suction Barrel 30 inch _ Pump Control Valve _ __24- inch RPM 1800 Estimated Engine (Waukesha) 440 BHP F18GSID N:~tlarWmgwr~.mot:~umtsuooswotv~imtreuda -2- TETRA TECH YORBA LINDA WATER DISTRICT Highland Booster Station Replacement/Expansion We have attached two preliminary pump station layouts in Appendix B. Figure 1 is a layout for electric motor driven pumps. It would be able to fit within the northeast portion of the existing facility. See marked up Sheet CIA. Figure 2 is a layout with engine driven or combination engine driven motor driven pumps. Major pieces of equipment include: engines, motors, right angle drives, drive shafting, heat exchangers, a single oil reservoir, battery boxes, pump control valves, butterfly isolation valves and suction and discharge headers. Cooling water supply and return piping for the engine can be concealed in a below grade pipe gallery to keep more available floor space. The pump station building would be located northwest of the existing facility. See marked up Figure C113. This location would require that the building be partially buried, see Figure 3. Access would be on the east side of the building. Ventilation would be provided through louvers on the east wall and a forced fan ventilation system exiting the roof opposite the intake louvers. This layout location is advantageous in that the area east of the building containing the existing pump station equipment will be allowed to be cleared. This will free up space to provide needed access to the new pump station's engines for future maintenance. There appears to be minor existing utility conflicts including an existing telephone line that may require relocation. The option with all new motors will require that the existing pad mounted transformer be upsized to accommodate the larger horsepower requirement. Another possible option to investigate is one that sizes the electric motors to take advantage of the existing engine generator. It has a capacity to operate 600 hp worth of motor power. The pumps could be designed so that at least two pumps would total 600 hp and be able to be powered by the full load of the generator. Instead of having four 400-hp pumps as shown in Figure 1, there could be one 400-hp 6,000 gpm, one 200-hp 3,400 gpm and two 500-hp 8,600 gpm pumps. The District may want to consider a 36-inch sized suction and discharge line which for the given expected flow rates would provide better head loss characteristics compared to a 30-inch pipe. 30-inch Suction Line Routing: It appears that routing the suction fine around the existing facility as shown on marked up C-IA would be advantageous from a constructability stand point. Routing the suction fine within the existing facility as shown in the exhibit attached with the RFP, would be difficult to construct, potentially affect the operation of the existing pump station; impact the existing electrical equipment, not to mention the mere difficulty of trenching for the 30-inch pipe through existing concrete floor and appurtenances. Cursory Surge Review: The existing pump station has a surge tower. The new pumping conditions will require more flow be pumped to the same 570 feet pressure zone. Tetra Tech will provide a cursory surge review for the new pumping requirements. We will determine if it is possible to re-use the existing surge tower or provide another method of surge protection. Due to the capacity of the pump station and the large size of the distribution system, a cursory review will be completed. A more detailed surge analysis can be provided in the next phase of design for the project if warranted. AQMD Moratorium on Issuance of Certain Air Permits: AQMD is required to make significant changes to its permitting program as a result of a recent court ruling. The court decision may substantially affect the District's activities if there are plans to install, construct, modify, replace or relocate equipment that emits air pollution. The court decision was that under federal and state law, AQMD can issue permits for new, replaced relocated or modified equipment only if emissions increases are "offset" by emissions reductions from other equipment. This moratorium could affect the District's decision to consider engines are an option to operate the new pumps. SCOPE OF WORK Tetra Tech project manager and engineer will attend a project kick-off meeting with District staff to discuss project issues and concerns, scope of work, review existing documents, staffing, schedule, deliverables and other project elements. Tetra Tech project manager and required project team members will visit Highland reservoir and booster station site to review current construction conditions, limitations and coordination for future expansion. Tetra Tech will gather data and information provided by the District, including construction drawings for the new 6 MG reservoir, the 2003 Highland booster upgrade project, transmission piping drawings from Zone 2 H:Haammewi+~w'1"NS~zOtYimotVvanOxex,.d« -3- TETRA TECH YORBA LINDA WATER DISTRICT Highland Booster Station Replacement/Expansion reconfiguration, as well as other pertinent drawings and information as necessary including environmental documents. We will review District provided 1995 and 2005 geotechnical report for the Mghland Reservoir by Leighton and Associates. We will review District provided June 2006 Mitigated Negative Declaration by Bonterra Environmental for the new 6 MG reservoir site. Tetra Tech will develop at least three layout options for the new 18,000 gpm BPS on-site. As one of the options we will evaluate the layout as shown in Exhibit 1V attached in the RFP. For each option developed we will identify risks, issues, concerns and limitations associated with existing conditions that may require compliance with existing regulations; codes, and other environmental regulation that may impact the future of the project. Tetra Tech will meet with District staff to review and discuss the options developed, including advantages and disadvantages for each and preliminary estimated construction costs and schedule. We will consider ml driven and engine-driven pumps. We will discuss the recommended alternative and why it's recommended. From meeting with District staff, Tetra Tech will prepare a draft EFS, presenting the three options. We will develop recommended option and prepare draft EFS in report format. We will furnish five copies of draft EFS to the District for review. Tetra Tech will meet with District staff to discuss review comments. We will prepare a final EFS incorporating and responding to all reasonable comments received. We will provide five bound copies of a final report and an electronic copy.

Estimated Costs: $20,000 Dept: Eng Subject: Amendment #4 to Professional Services Agreement with Carollo Engineers For Design of Hidden Hills Reservoir SUMMARY: In the process of preparing the final design plans for the Hidden Hills Reservoir Project, the design consultant, Carollo Engineers, performed additional work beyond its contractual scope. Carollo Engineers is requesting an amendment to its scope and fee for this additional work at a cost of $20,615. DISCUSSION: In December 2004, the Board approved a Professional Services Agreement (PSA) with Carollo Engineers for design of the Hidden Hills Reservoir Project. The project has gone through various delays and changes; however, it has now been advertised for construction bids. In October 2006, the Board approved an amendment to Carollo's PSA for the project for additional design work requested by the District. At that time, Carollo indicated in its August 31, 2006 letter concerning the extra work, that it would be performed, provided there was no significant shift in the centerline of the utility easement or property boundaries that would require major revisions to the reservoir grading and piping plans, roadway plans and profiles, and pipeline plans and profiles. Unfortunately, when Carollo was recently requested to finalize the project design plans after various issues were resolved, it was determined that significant changes were necessary with the utility easement, as summarized on the attached letter of December 9, 2008 from Carollo. As indicated in the December 2008 letter and attachments, the cost to perform the changes totaled $20,615. Carollo is requesting a change order for the cost of these additional services. District staff reviewed the documentation, discussed the issue with Carollo, and recommends approval. PRIOR RELEVANT BOARD ACTION(S): November 9, 2004, Board authorized staff to execute an agreement with Carollo Engineers for the design of the Hidden Hills Reservoir Project. November 22, 2005, Board authorized staff to execute an amendment to the PSA with Carollo for design of the Santiago Booster Station Upgrades. October 26, 2006, Board authorized staff to execute an amendment to the PSA with Carollo Engineers for $26,500 for additional services for the Hidden Hills Reservoir Project. STAFF RECOMMENDATION: That the PEO Committee recommend that the Board approve Amendment #4 to the PSA for Carollo Engineers for Hidden Hills Reservoir Project for additional design services for a total fee not to exceed $20,615.

I Subject: Additional Work Associated with the Final Design of the Hidden Hills Reservoir Dear Mr. Conklin: In reference to the previous Amendment to the Engineering Design for the Hidden Hills Reservoir Project dated August 31, 2006, additional work associated with the final design was incurred with respect to the discrepancies in the base map files. Under task 3 of the amendment, assumptions were made that no significant shift to the centerline of the utility easement would be encountered. However, as discussed with you two weeks ago, in finalizing the drawings the following additional work associated with the utility easement provided were required: 1. Pipeline alignments needed to be modified within the given easement as well as the clearances between pipelines. Horizontal alignments stationing also needed to be updated. 2. All three Pipeline plan and profile sheets needed to be revised to reflect the correct alignment and layout. Text modifications and curve data call outs needed to be revised. Based on 44 hours of engineering (Maria Alvarez) and 76.5 hours of CAD design (Ben Hawes), our cost for these additional services totals $20,615 (44hrs x $197/hr + 76.5hrs x $142/hr + 120.5hrs x $9/hr (PECE)).

Bonds Account No: 401-2700 Job No: 200028 CEQA Compliance: Mitigated Neg. Dec. Estimated Costs: $ 6.4 M Subject: Consultant Agreement Addendum with Carollo Engineers for Hidden Hills Reservoir SUMMARY: The District's 2005 Water Master Plan Update established the proposed Hidden Hills Reservoir capacity at 1.86 million gallons (MG) to meet operational and emergency needs for the local service area. Carollo Engineers Is designing this reservoir along with upgrades to the Santiago Booster Pump Station, which pump to this reservoir. These plans are currently 90% completed. Carollo has performed additional services beyond their original scope of work and has provided the District with an estimated fee not to exceed $26,500 for these services and additional tasks requested by the District to complete the plans and specifications for this project. DISCUSSION: Carollo has submitted a request for an addendum to their Consultants Agreement in an amount not to exceed $26,500, for additional work required to complete the plans, specifications and contract documents for the Hidden Hills Reservoir and Booster Pump Station project. These services include the review and coordination of boundary survey information, preparation of a hydrology report and hydraulic analysis of downstream storm drain systems, and survey and design for an additional grading and construction easement. Carollo based their engineering design and plan set development on field survey work previously performed by Tetra Tech in 2001 and 2004. Carollo has had to provide additional coordination and engineering efforts to clarify discrepancies between this data, recorded easements and grant deeds and work improvements proposed by Shapell Industries in extending Hidden Hills Road for construction of homes north of the existing end of the street. Carollo has requested $11,550 for these services. In the course of utility planning and coordination with the City of Yorba Linda for the reservoir site drainage, drain line and overflow systems connecting to the City's storm drain in Hidden Hills Road, Carollo was required to analyze the City's existing downstream collection system to confirm it has sufficient capacity to accept the additional flows. Caroilo prepared a hydrology report and performed hydraulic analysis on the downstream system for a fee of $6,420. In preparing the utility and access road plans Carollo determined the District will need a temporary construction and grading easement beyond the limits of the existing easement previously granted by Shapell Industries, Inc., the property owner. Carollo has prepared an estimate not to exceed $8,530 for these efforts. PRIOR RELEVANT BOARD ACTION(S): On November 9, 2004, the Board of Directors authorized staff to execute a Consultants Agreement for the design of the new 2MG Hidden Hills Reservoir, Job No. 200028. On November 22, 2005, the Board of Directors authorized staff to execute an amendment to the Consultants Agreement with Carollo for design of the Santiago Booster Station Upgrades.

Check discrepancies in the deeds and base map files provided by the District: This task includes the effort spent to check and identify the discrepancies In the deeds and base map files, as summarized in our letter dated August 30, 2006, which may require further clarifications and possibly revised deeds and base map files be prepared for use in the final design of the reservoir facilities. 2. Prepare a hydrology report: At the request by the District, Carollo prepared a hydrology report in response to a request by the City of Yorba Linda for the connection of the new 18-inch diameter storm drain to the City's storm drain system. 3. Revise design drawings per the revised deeds and base map: As a result of the discrepancies identified in Task 1 above, the 90 percent final drawings may have to be modified per the revised tract boundaries, reservoir site property lines, and easements to be confirmed by the surveyor. An estimated effort for the possible revisions to the drawings is presented in Exhibit A includes checking and adjusting the property boundaries and easements on the final design drawings assuming no significant shift in the centerline of the utility easement or property boundaries that would require major revisions to the reservoir grading and piping plans, roadway plans and profiles, and pipeline plans and profiles. 4. Design of water sampling stations for Camino de Bryant and Elk Mountain Reservoirs: The District currently takes water samples via the roof hatches in the existing reservoirs. The new sampling stations would enable the operations staff to take water samples from locations other than the access hatches and at two to three selected elevations in the reservoirs.

The study has been completed and is being presented to the Committee for review and consideration. A copy of the final report, titled "Irrigation Feasibility Study," prepared by Metcalf & Eddy/AECOM, is attached. At the same time that report was in progress, staff performed a preliminary water quality investigation, which is also attached and titled "Status Report on Feasibility Investigation of Irrigation Water Project." DISCUSSION: Please refer to the attached Status Report for information on the background, proposed project, water quality investigation, summary of the Irrigation Feasibility Study, and conclusions. As noted in the attached documents, the proposed project is to construct a new well at the site of the two abandoned wells, and use the existing 16-inch pipeline to carry the water to landscaped sites along or near the alignment of the pipeline. A Water Well Feasibility and Siting Study completed for the District in 2006 indicated that it is feasible to drill and construct a new well at the former well site. Well production would be limited to about 500 gallons per minute due to limited water-bearing deposits and underlying bedrock. The study also found that the water would be usable for landscape-supply purposes only due to elevated concentration of total dissolved solids and other minerals. The Conclusions in the Status Report states that, based on the preliminary information on water quality and soils, there is concern for potential soil clogging and resulting growth problems for grass and foliage. Concerning project economics, the life-cycle cost comparison in the Irrigation Feasibility Study indicated that Phase 1 development might be cost-effective over 25 years, but not Phase 2. Based on water quality concerns and cost-effectiveness, the project appears questionable. Accordingly, the recommendation of staff is not to pursue the project. PRIOR RELEVANT BOARD ACTION(S): None. STAFF RECOMMENDATION: That the Committee recommend that the Board of Directors receive and file the Final Irrigation Feasibility Study and that there be no further consideration of the project. ML 7W MEMORANDUM DATE: January 29, 2009 TO: Ken Veechiarelli, General Manager FROM: Steve Conklin, Engineering Manager SUBJECT: Status Report on Feasibility Investigation ofIrrigation Water Project The District is proceeding with an investigation into the feasibility of developing a non-potable irrigation water system at the far easterly end of the district, in the vicinity of La Palma Avenue and Camino de Bryant. The project would make use of groundwater not meeting drinking water standards because of high-mineral content, but otherwise safe and reliable. The water will be used for irrigation of grass and landscaping in parks, greenbelts and parkways and will conserve potable water now used for this purpose. I Background In the early 1990s, two groundwater wells were dedicated to the District by local developers, and renamed District Wells 16 and 17. The water from those wells was high in total dissolved solids (minerals), and required blending with imported water to meet potable water quality standards. The well water was carried from the wells through a 16-inch diameter ductile iron pipeline, approximately 8,300 feet, to the Elk Mountain Reservoir, where the well water was blended with imported water for distribution. The pipeline and reservoir were developer-provided and dedicated to the District. Over time, the quality of the well water deteriorated to the point that blending no longer yielded acceptable quality water due to mineral content. At that time, the Board made the decision to abandon and cap the wells, and to meet the local water demand with imported water only, supplied to the reservoir. The existing 16-inch pipeline from the site of the wells to the reservoir was no longer needed and is currently unused. Proposed Project The proposed project is to construct a new well at the site of the two abandoned wells, and use the existing 16-inch pipeline to carry the water to landscaped sites along or near the alignment of t the pipeline. A Water Well Feasibility and Siting Study completed for the District in 2006 indicated that it is feasible to drill and construct a new well at the former well site. Well production would be limited to about 500 gallons per minute due to limited water-bearing deposits and underlying bedrock. The study also found that the water would be usable for landscape-supply purposes only due to elevated concentration of total dissolved solids (TDS) and other minerals. Data from other wells indicated that the TDS concentration might be in the range of 700 to 1200 mg/l. The State's secondary standard for TDS is 500 mg/l. Potable water provided by the District in that area (imported water) has a TDS concentration of approximately 378 mg/l. Water Quality Investigation District staff did a follow-up investigation to determine how other nearby facilities are faring, located near the Santa Ana River and using well water. Located not far upstream is the Green River Golf Club, which irrigates with water from wells near the river. Data from 2006 and 2007 indicates that the water from those wells had a TDS concentration in the range of 1015 to 1254 mg/l. The grass and landscaping at the golf course looked very good based on a site visit by District staff. Alan Andreason, the golf course superintendent indicated that they use salt- tolerant grass strains and over-water approximately 15% to leach the salts out of the grass. He said that they are successful, but close monitoring, over-watering, chemical treatment and maintenance are required. He also noted that, while they have reduced water use somewhat, their wells are not metered, and water is used as necessary to keep the course green and lush. Located downstream of the proposed new well site is Featherly County Park and Canyon RV Park, which has two water wells. District staff visited the site and was informed that the well water is disinfected and used for irrigation and for drinking. Recent test data indicates TDS concentration in the range of 600 to 700 mg/l and no problems. Lastly, staff visited Neff Ranch, which is immediately adjacent to the proposed site for the new well. The existing Bryant Well at Neff Ranch is used for irrigation of orange trees, on property leased to Neff Ranch from the County of Orange. District staff visited the site and were informed that the orange trees are doing well with no problems with the water. On a return visit, District staff collected a well water sample for analysis. The analysis indicated a TDS concentration of 1100 mg/l, which is similar to analyses in 2003 and 2005, showing TDS concentrations of 1200 and 1300 mg/l, respectively. Being that the Bryant Well is very close to the proposed new well, current data from this well is considered the best indicator of expected water quality for the proposed well. In addition to TDS, other water quality parameters important for landscape irrigation were analyzed for the Bryant Well. That data was submitted to Dr. Ali Harivandi at the UC-Davis School of Agriculture, a specialist in the use of marginal-quality water for irrigation. After reviewing the data, Dr. Harivandi called the water "borderline on the good side," adequate for turf-grass but a concern for its effect on ornamental plants. He recommended an evaluation of the soil at the user sites. Dr. Harivandi noted that successful use will require site management and education of the staff maintaining the sites. He also pointed out that the water might be fine 2 for years with normal rainfall (13+ inches per year) to leach and dilute, but problematic with multiple dry years when there is no leaching. This leads to the need for site management, such as chemical additions, flushing, etc. Dr. Harivandi recommended that Dr. Larry Stowell at Pace Consulting be contacted, a specialist in landscape management for golf courses and other areas. Alan Andreason of Green River Golf Club also recommended Dr. Stowell, who is a consultant for Green River. Dr. Stowell was contacted and said that what has been found over the years with use of high-TDS water is that the best indicator of success is the type and condition of the soil receiving the water. The best soil condition is sandy with good drainage. Soils with clay and silt and poor drainage are problematic. Some general comments from Dr Stowell: • Bermuda grass does ok. • Trees may not fare well, but do better if the water drains away and does not collect around the trees. • Some foliage my not do well, particularly with spray irrigation; conversion to drip and bubblers is an improvement. • Over-watering may result in better growth and acceptance of the water. Perhaps 15-20% more water may be required. Dr. Stowell was sent site and water quality information and was requested to provide a proposal on what the next steps might be in the process of determining if the District should proceed with the cost of drilling a new well. In the response from Dr. Stowell, he stated that the site is complex with many soil types and lots of slopes. Some of the soils have very low hydraulic conductivity that will make irrigation more difficult. The low hydraulic conductivity clay- containing soils will also respond poorly to high sodium irrigation water. Leaching to manage salt accumulation that results from irrigation will also be difficult on soils with low hydraulic conductivity. Dr. Stowell said that the question to be asked is: What are the management practices and plant types that will perform to expectation using the well water? He said that the answer to that question is not so simple and will depend upon what type of management options will be available following adoption of well water use. If planting pits for trees are properly constructed (deep and wide enough with good drainage and filled with a sandy soil) tree management will be feasible. If salt sensitive and high-water-using cool season turfgrasses such as tall fescue or ryegrass are going to be used, leaching will be needed and soils must be well drained. If bermudagrass or paspalum are going to be planted, salinity accumulation is not such a great concern but winter color is a problem (these grasses go dormant and must be either painted or overseeded - resulting in other problems). Dr. Stowell indicted that he is booked up through the winter and would be unable to assist much further in the near future. He recommended the following be considered: 3 I . Characterize the current water source and compare and contrast to the new well water quality. If the new well water is within 10% of the TDS, bicarbonate, sodium and SAR of the current water source, there should be no serious problem - no guarantees, but the risk is low (of course, other factors should be considered but these four are easy to evaluate). This assumes that the current water source is performing well under all conditions at the site. 2. If the well water is of substantially lower quality compared to the current well water, the site will need to be characterized for areas of high risk from damage if the well water is used. The attached soil maps and areas with less than 7 um/sec saturated hydraulic conductivity are targets for additional study. 3. Propose modified and soil management practices based upon the new well water source, soil conditions and plant types. In response to Dr. Stowell's recommendation that the quality of the current water source be compared to that expected in the well water, Bryant Well water was compared to that currently being delivered by the District into that area, as shown below: Bryant YLWD Percent Parameter Well Water Variation m a b a-b /a x 100 Calcium 170 37 78% Magnesium 44 17 61% Sodium 130 65 50% Chloride 150 66 56% TDS 1100 378 66% H 7.5 8.2 9% Per Item 1 above, Dr. Stowell suggested that if the two water sources have water quality parameters within 10% of each other there should be no serious problem. However, for the two water sources above, the percent variation is much greater than 10% for all parameters except pH. Based on this guideline from Dr. Stowell, it can be inferred that there may be significant problems using the well water for irrigation. In the information above, Dr. Stowell notes that information from the U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS) indicates that the proposed area to receive the well water for irrigation is complex with many soil types and lots of slopes. Some of the soils have very low hydraulic conductivity that will make irrigation more difficult. The low hydraulic conductivity clay-containing soils will also respond poorly to high sodium irrigation water. Further, in Item 2 above, he notes that if the quality of the water is low (as shown in the above table) there may very well be problems applying it to soils with a low saturated hydraulic conductivity of 7 um/sec or less. This parameter, from information provided by the NRCS, refers to the ease with which pores in a saturated soil transmit water, expressed in terms of micrometers per second. The parameter is a 4 function of soil characteristics, particularly structure, porosity, and texture, and is an indicator of soil drainage. Included at the end of this memo is information from the NRCS for the proposed project area, including: • A map showing soil types in the area proposed to receive the well water for irrigation. The soil types were determined by the NRCS. • A map unit legend for the soil types shown on the map, a description of each soil type, and a breakdown of the acreage and percent of the total area addressed. • Physical Soil Properties information, including the estimated Saturated Hydraulic Conductivity (SHC) for each soil type. From the above information the following was tabulated regarding the soil conditions: Soil Characteristics for the Proposed Project Area General Approx. Percent of SHC Soil Area Total Value Characteristic acres Area 1.4 - 4.0 Poor drainage 59 6.5% 4.0 - 14.0 Marginal drainage 464 51.2% 14 - 42 Good drainage 337 37.2% 42 - 141 Very good drainage 46 5.1% Total 906 100% From the tabulated soils information summarized from data provided by the NRCS, the table indicates that approximately 57.7% of the total project area has soil that is estimated to have "poor" (6.5%) to "marginal" (51.2%) soil-drainage characteristics. The balance (42.3%) is estimated to have "good" to "very good" soil-drainage characteristics. In summary, the above information indicates that over half of the total proposed project area may have poor to marginal drainage problems if the well water is used. This may translate to clogged soils and problems growing grass and foliage. This is an important issue that would need to be discussed with the City of Yorba Linda, because most of the irrigation sites are maintained by the City. The City would need to understand the cost and implications of changing to the new water source. Irrigation Feasibility Study An investigation titled "Irrigation Feasibility Study" was completed in January 2009 and determined that 23 landscaped sites along the pipeline route could be served in the first of a potential two-phase project. The existing 16-inch diameter pipeline would be used. Also required would be the construction of a new well and appurtenances, pipeline laterals to reach the irrigation users, and a 370,000 gallon steel reservoir and site improvements. Based on a review 5 of historical water use, those 23 sites consume an average of 184 acre-feet per year of potable imported water that could be saved by using the non-potable groundwater. Phase 2 would consist of constructing 11,300 feet of 12-inch pipeline and service laterals from the existing 16-inch mainline to reach 15 more users with an estimated annual demand of 55 acre feet. With the implementation of Phase 2, the combined system would include 38 users and an average of 239 acre-feet per year of non-potable water consumption. The Irrigation Feasibility Study made a determination of the estimated capital facilities and construction cost required for each of the two phases. A life-cycle cost comparison was made for each phase for a 25-year life. The comparison included the cost of non-potable groundwater versus the cost of Met water over the 25 years. Based on the factors in the study, the finding was that for Phase 1 development, the average non-potable water system cost was $1,470 per acre- foot versus $1,544 for MWD Full-service water. That is, under this scenario with Phase 1 development, non-potable water would be approximately 5% less costly than MWD water in 25 years. However, for Phase 2 development, the non-potable water system cost would be $2,102 per acre- foot versus $1,543 for MWD Full-service water. Thus, it does not appear that Phase 2 development is reasonable for further consideration. Conclusions Based on the preliminary information above on water quality and soils, there is concern for potential soil clogging and resulting growth problems for grass and foliage. Concerning project economics, the life-cycle cost comparison indicated that Phase 1 development might be cost- effective over 25 years, but not Phase 2. Based on water quality concerns and cost-effectiveness, the project appears questionable. Conversely, the other consideration is that the project would make use of a currently under- utilized non-potable water source for irrigation purposes. The project would reduce the demand on potable water at a time of supply limitations and increasing demand. With this in mind, further evaluation of this water source may be prudent. 6 .i W METCALF&EDDY AECON/I January 5, 2009 Ken Vecchiarelli Assistant General Manager Yorba Linda Water District 1717 E.

Introduction 1.1. Project Description In an effort to incorporate a non-potable water system for irrigation use into its Capital Improvements Program (CIP), the Yorba Linda Water District (District) wishes to investigate the feasibility, both logistically and economically, of developing a non-potable water system in the Improvement District No. 2 (ID2) Bryant Ranch area, in the City of Yorba Linda. This feasibility study will evaluate installing a new well in the District's existing abandoned Wells Nos. 16 and 17 site to provide a source of water for nearby irrigation needs. 1.2. Background The project area is located in the City of Yorba Linda in Improvement District No. 2, also known as Bryant Ranch. ID2 is located on the eastern portion of the City of Yorba Linda, north of the Santa Ana River and south of Blue Mud Canyon and Wire Spring Canyon. The area consists of relatively steep hillsides with several housing developments on the southern portions. The site of Wells No. 16 and 17 is located approximately 1,000 feet east of River Bank Drive just north of Highway 91, and 2.8 miles east of the intersection of Yorba Linda Boulevard and Highway 91. I Currently, these wells are abandoned and capped. These are shallow wells, approximately 90 to 100-feet deep, and had an expected operating capacity of around 500 gpm each. However, due to characteristics of the hydrogeology and the zone of interference, the combined well output was 600 to 700 gpm. The existing system also included a 16-inch ductile iron pipeline, approximately 8,310 linear feet, which carried the well water flow to the Elk Mountain Reservoir, where the groundwater was blended with other higher quality water. The 16-inch pipeline alignment runs from the Wells No. 16 and 17 site, west along Brush Canyon Drive, north on Camino de Bryant, and north on Elk Mountain Drive to Elk Mountain Reservoir. The existing 16- inch pipeline is abandoned now. Wells Nos. 16 and 17 were abandoned due to the deterioration of water quality to the point that blending no longer yielded acceptable water quality. Water quality issues include high manganese (Mn), iron (Fe), and total dissolved solids (TDS). The existing Elk Mountain Reservoir is a 6 MG buried reinforced concrete tank. The project area includes a school and two (2) parks: Bryant Ranch School, Brush Canyon Park and a park located next to Bryant Ranch School on Paseo de Toronto. Figure 1 illustrates an aerial photo of the project vicinity.

Project Purpose The purpose of this project is to investigate the feasibility of using the existing well site, with a new well, as a source of water for nearby irrigation needs. A hydrogeology report entitled "Water Well Feasibility and Siting Study" for the well site was prepared by Richard C. Slade & Associates (RCS) in September 2006. The proposed project would be to drill and equip a new well and utilize the existing, unused 16-inch pipeline as a transmission pipeline of non-potable water. A new reservoir would be proposed near the existing Elk Mountain Reservoir to store the non-potable water. Additional irrigation users, such as greenbelts, schools, parks, etc., could be added to the system in the two implementation phases described below. Initially, there are 2 implementation phases planned for the irrigation water system as follows: 1. Phase 1 would consist of drilling and equipping a new shallow well, approximately 90-100 feet deep, at the abandoned Well Nos. 16 and 17 site, and connect to the existing 16-inch ductile iron pipeline. The existing pipeline is approximately 8,310 linear feet long. Before any design and construction can begin, a pipeline assessment would need to be conducted to determine the condition of the existing pipeline. If the pipeline assessment determines the integrity of the existing pipeline is unable to meet applicable codes and regulations, a new pipeline would need to be considered for the proposed irrigation system, thereby increasing the capital cost. The cost of installing a new 16-inch pipeline, for example, alone can be upwards of $1.3 million, not including utility relocations, and demolition of the existing M ETCALF & EDDY Page 2 January 5, 2009 YORBA LINDA WATER DISTRICT IRRIGATION FEASIBILITY STUDY FINAL REPORT pipeline if another pipeline alignment is unavailable. However, if an assessment proves the existing pipeline worthy, the project could move forward. For the purposes of this study, it is assumed that the existing pipeline is usable for the proposed project. Ten irrigation users adjacent to the existing pipeline will be connected to the irrigation system first. Various 8- inch laterals would be installed, approximately 2,500 linear feet total, to connect thirteen users that are not immediately adjacent to the existing 16-inch pipeline. A new steel storage reservoir would also be constructed near the Elk Mountain Reservoir for the storage of non potable water. 2. Phase 2 would consist of designing and installing a new 12-inch pipeline. This new pipeline alignment will connect to the existing 16-inch ductile iron pipeline near the intersection of Paseo de Toronto and Via Cantada, continue west along Paseo de Toronto, continue south along Via Lomas de Yorba East, turning east along La Palma Avenue, continuing north along Camino de Bryant until it connects to the existing 16-inch ductile iron pipeline to form a loop within the pipeline system. The new pipeline will be used to convey irrigation water to fifteen new users along the new pipeline alignment. At the end of this phase a total of 38 irrigation users would be connected.

Scope-of-Work This Feasibility Study includes the following tasks: 1. Investigate the feasibility of installing and equipping a new shallow well with a capacity of 500gpm in the vicinity of YLWD Wells No. 16 and 17 as the supply source for a non- potable water system in the ID2 service area. Collect and review GIS maps with historic demand data provided by YLWD. Review existing well studies provided by YLWD. Provide a demand analysis compared to well capacity. 2. Provide a phased approach for installing a non-potable water system and connecting irrigation users in the ID2 service area. 3. Determine the economic feasibility of constructing the proposed irrigation water system. Provide an order-of-magnitude cost estimate for the construction of the system by phase. Provide a life cycle cost analysis for each phase. Consider the replenishment cost to the Orange County Water District for pumping well water and system revenue. Compare to purchasing full-service treated water from Metropolitan Water District. 4. Provide draft and final report. M ETCALF & EDDY Page 4 January 5, 2009 EIYORBA LINDA WATER DISTRICT IRRIGATION FEASIBILITY STUDY FINAL REPORT 2. Proposed System Evaluation 2.1. HYdro9Bolo9is Evaluation Based on the study "Water Well Feasibility and Siting Study" by Richard C. Slade & Associates in September 2006, it is "hydrogeologically feasible to locate, drill and construct new wells for YLWD on their property on the north side of the river within Santa Ana Canyon." Furthermore, "flow rates on the order of 500 gpm appear feasible." The study recommends a variable frequency driven (VFD) pump for higher and/or lower ranges of pumping depending on the season, depth to water, specific well capacity, and overall well efficiency. The hydrogeologic study reported water quality characteristics to be very similar for both abandoned Wells Nos. 16 and 17, and anticipated similar water quality for the proposed irrigation supply well. The abandoned wells had high total dissolved solids (TDS), and high total hardness (TH). On occasion, the wells produced water with elevated levels in iron, manganese, and turbidity. Therefore, based on the unfavorable water quality, the hydrogeology study recommends that the proposed water supply well be solely used for irrigation purposes. The study made the following conclusions and recommendations about the proposed irrigation supply well: Table 1: Conclusions and Recommendations for Proposed Irrigation Supply Well (by RCS) Unit Value/ range Drilled well depth, maximum Feet 125 Casing depth Feet 100 to 110 Blank cellar casing below bottom of perforations Feet 20 to 30 Casing diameter Inches 16 High strength-low alloy Casing material type Type (HSLA, aka Corten steel) Super-Flo louvers as by Roscoe Perforations type Type Moss Co.

Demand Evaluation The District has provided customer service meter data for irrigation users for the 5-year period between July 2002 and June 2007. The District identified 38 irrigation users that could be connected to the new non-potable water system. Tables 2 through 4 show irrigation demand by M ETCALF & E DDY Page 5 January 5, 2009 YORBA LINDA WATER DISTRICT IRRIGATION FEASIBILITY STUDY FINAL REPORT 38 proposed users system-wide and by the two phases, respectively, for determining the feasibility of meeting irrigation demands. Table 2: Irrigation Demand b 38 Proposed System Users, based on Jul 2002-June 2007 Data Volume in gallons (gpm) Max Monthly Demand 11,152,706 gallons 258.2 gpm Average Monthly Demand 6,484,451 gallons 150.1 gpm Note: 1. GPM was calculated based on 30-day month, 24-hour/day, 60 min/hour average rate. Table 3: Phase 1 Irrigation Demand by first 23 Users, based on Jul 2002-June 2007 Data Maximum month Maximum month gallons (gpm) month Maximum Month Irrigation Demand 8,638,504 Aug 2004 200.0 gpm Maximum Single User 1,438,504 Oct 2002 33.3 gpm Average User demand for this Phase 217,143 5.03 gpm Average Monthly Demand, 23 users 4,994,282 115.6 gpm N ote: 1. GPM was calculated based on 30-day month, 24-hour/day, 60 min/hour average rate. Table 4: Phase 2 Irrigation Demand by additional 15 Users, based on Jul 2002-June 2007 Data Maximum month Maximum month gallons (gpm) month Maximum Month Irrigation Demand 2,836,613 Sept 2006 65.7 gpm Maximum Single User 1,538,743 June 2003 35.6 gpm Average User demand for this Phase 99,345 2.30 gpm Average Monthly Demand, 15 users 1,490,169 34.5 gpm Note: 1. GPM was calculated based on 30-day month, 24-hour/day, 60 min/hour average rate. 2. Demands are not cumulative, i.e. does not include Phase 1 and Phase 2 demands. The historic data shows that the highest average demand rate for all combined 38 users was 258.2 GPM, significantly below the average capacity of the proposed well output. However, this value cannot account for actual instantaneous peak demand, which can be many factors higher than the average calculated above. Nevertheless, these peak demands can be mitigated later with proper storage reservoir and pipeline sizing using appropriate peaking factors. For now, M ETCALF & E DDY Page 6 January 5, 2009 EIYORBA LINDA WATER DISTRICT IRRIGATION FEASIBILITY STUDY FINAL REPORT the purpose of this analysis is to determine whether there is enough capacity at the proposed well site for the proposed 38 users on an average basis. A 370,000-gallon steel tank is proposed, based on 1 day of storage at max-day demand. 2.3. Constructability evaluation The District owns all right-of-ways that are needed to install a new irrigation water system in the ID2 area. This includes rights to land for a new irrigation supply well near abandoned Wells Nos. 16 and 17, land for a proposed 370,000-gallon above-grade steel tank next to the existing Elk Mountain Reservoir, and rights to the new proposed pipeline alignments. See Figure 2 for the aforementioned facility locations. In addition, the District owns the abandoned 16-inch pipeline, which runs from the abandoned well site to the existing Elk Mountain Reservoir site. Because the pipeline has been abandoned for a number of years, it is recommended that a non- destructive inspection of the entire pipe length be performed to determine that the integrity meets applicable codes for its intended use. However, for purposes of the cost estimate in the next section, it will be assumed that the pipeline will be re-instated for water transmission use and minimal cost will be associated with returning it to service. Anticipated construction will not involve special construction methods. Conventional construction for PVC or ductile iron pipeline is anticipated, involving trenching in City of Yorba Linda streets, typically 3 to 5 feet of cover and compaction, and re-paving of the streets, as shown on Figure 3.

Cost Evaluation The proposed irrigation water supply system would require a condition assessment of the existing pipeline, along with capital costs of new facilities. The cost for a condition assessment by video surveillance of the existing 8,310-foot pipeline would be on the order of magnitude of $25,000. The system would consist of the following preliminary and simplified list of new facilities: 0 One irrigation supply well with 500 gpm capacity; • 370,000-gallon reservoir, size based on 1 day supply at max-day demand; • 11,300-ft of 12-inch PVC pipeline to extend system and to close irrigation loop; • 2,500-ft of 8-inch PVC pipeline (diameter assumed for now) for laterals to reach irrigation users not immediately near the abandoned and new loop pipeline; and • 38 new irrigation service connections. Based on the above preliminary list of new facilities, the Table 5 was developed to calculate an "order-of-magnitude" cost estimate by system implementation phase.

Life Cycle Cost Comparison A life cycle cost was developed for the irrigation feasibility study which includes the capital cost of a new irrigation system and associated facilities, the cost to replace those facilities at the end of the analysis period, the replenishment cost of pumping groundwater, and interest paid on the capital cost. For simplification of this feasibility study, the phases were assumed to be implemented within the first year. However, realistically the phase-implementation would be staggered over the course of a few years if it was decided to proceed with each respective phase. This cost was compared to the cost of buying water from Metropolitan Water District (MWD). The analysis cycle period was selected at 25 years, and all costs were calculated with the future value function given present values and estimated escalation and interest rates. The replacement cost of each facility component was calculated based on the fraction of the cycle period to the estimated life span. For example, the cost of replacing a facility with the an estimated life span of 50 years was calculated to be half of the future value at 25 years given today's capital cost and the annual inflation rate. The life cycle cost of MWD water was based on the current rate per acre-foot, and an average historical escalation rate based on yearly rates from calendar year 2003 through 2009. Table 6 tabulates the life cycle costs for each option.

Interest on capital cost based on 15 year bond at 4% interest The results indicate that the cost of implementing Phase 1 of the proposed irrigation system after 25-year period are comparable to that of purchasing water from MWD. However, as the second phase is implemented, the cost of the proposed irrigation system increases significantly compared to that of purchasing MWD water over the course of 25 years, and based on the life- cycle assumptions.

Conclusions Based on the available data and hydrogeologic study, it is hydrogeologically feasible to supply a new irrigation system in the ID2 zone of the District. The hydrogeologic study by RCS concludes that water is available for irrigation purposes from the existing abandoned Wells Nos. 16 and 17 sites at 500 GPM. The demand evaluation concludes that the maximum month irrigation water demands for the proposed 38 irrigation meters of approximately 258 GPM is within the supply capacity. However, this demand does not account for instantaneous peak demands. Nevertheless, these peak demands can be mitigated by proper storage and transmission pipeline design. A preliminary "order-of-magnitude" cost estimate resulted in a constructed cost of $3.91 million. In addition, an irrigation system would save the cost of purchasing potable water that can otherwise be used for drinking, other domestic and industrial needs. The volume of water that would be saved from the domestic water system is described in Table 7. The table also shows the average cost per year per ac-ft of water for implementing each phase compared to the cost of purchasing MWD water. Table 7: Average Annual Cost of Irrigation System by Phase compared to MWD Water over 25-yr life cycle Phase Volume of Average Non-potable Water Average MWD Full-service Water Water System Cost Cost (ac-ft/year) ($/ac-ft/year) ($/ac-ft/year) 1 183.92 $1,470 $1,544 1 and 2 238.80 $2,102 $1,543 Notes 1. Demands are based on 5-year average provided by YLWD, July 2002 to June 2007. Similar to the life cycle cost trend in the previous section, the cost per ac-ft of water is comparable to purchasing MWD water if the first phase is implemented. However, the cost increases significantly as the second phase is implemented, but will depend on the actual increase in the MWD rate. Based on the analyses presented in this study, it is recommended that the District consider further a more detailed study for implementing this phased approach. The project would make use of a currently under-utilized non-potable water source that can be used for irrigation purposes. At the same time, the project would reduce the demand on potable water, be it imported water or local groundwater, at a time of supply limitations and increasing demand. Accordingly, it would be prudent for the District to further consider adding "irrigation" water to its portfolio.
