address the pressure fluctuations and determined the best solution to be the installation of a pressure booster station at the sports park. The water pressure booster will supply recycled water to the sports park at a pressure that allows the irrigation system to function under all operating conditions. The pressure booster station will also have the added benefit of providing good pressure and flow to support the Valley Avenue recycled water extension and eventual pumping to Callippe Preserve Golf Course. As envisioned, the booster station project will install a "packaged" station in the sports park where the existing Arroyo Mocho undercrossing is located adjacent to Harvey Court. The "packaged" booster station will be in a fiberglass enclosure measuring approximately 6-feet in height, 10-feet in width and 20-feet in length. The station will be placed inside a screened, fenced area and surrounded by landscape plant screening to match other locations in the park. Planning and Parks staff will be involved in determining the exact location of the station. The estimated cost to complete the design and construction of the booster station is $400,000. The booster station will be purchased by the City and the installation and associated pipeline work will be accomplished through a change order to Ranger Pipelines if the timing aligns with their work on the project. If timing for a change order does not work, the booster station installation may be bid as an independent project, or be bid as part of the Valley Avenue Recycled Water Extension project. RMC Water and Environment provided design services for the Recycled Water Infrastructure Expansion Phase 1A project, CIP No. 141026, and is providing engineering support for the project during construction through Amendment One to their original design contract. Staff is recommending approval of Amendment Two to the Agreement with RMC Water and Environment to provide design services for a water pressure booster station. The second amendment is Attachment 1 to this report and is for a not-to exceed amount of $74,687. The amendment also extends the contact term to April 30, 2017. Remaining Grant and Loan Balance after the Recommended Additional Work As stated earlier in this report there is currently approximately $2,532,000 remaining Loan and Grant funds that can be used to improve or expand the recycled water distribution system. The three recommended components of work in this report total an estimated $1,475,000, leaving a remaining balance of $1,057,000 in Loan and Grant funds. The Engineering and Operations Services Department are reviewing alternatives to use these funds. At this time it is preferred to hold this amount available while the newly constructed system is put into service with customer connections. If it is determined that additional work is required or desired for the remaining Loan and Grant funds, staff will bring forward a recommendation at a future date. Page 7 of 8
