City ofSanta Ana EXHIBIT A y i 'M The City of Santa (City) operates a potable water distribution system that serves over 44,000 water services. The City's potable water is obtained either by pumping from 21 existing groundwater wells or imported from several Metropolitan Water District connections. The City has some wells that produce groundwater with elevated nitrate levels. The City has developed a Nitrate Blending Plan and mixes the high nitrate groundwater with low nitrate groundwater. Well #32 has elevated nitrate levels. Well #32, located at Morrison Park, has been inactive for over the past nine years due to low operating efficiencies and high nitrate levels. The City desires to increase their groundwater pumping capacity and lessen their reliance on imported water. The intent of this project is to rehabilitate Well #32 and place it back into service. Instead of treating the high nitrates at the well site and impacting Morrison Park, the City intends to incorporate Well #32 into the City's nitrate blending plan. Water from Well #32 will be pumped to the John Garthe Reservoir site. The City blends low nitrate water from Well #36 and #39 (located at the John Garthe site) with higher nitrate water from Well Nos. 18 and 24. The following are typical key issues which we believe must be addressed to successfully complete design services: Meeting schedule 19 Coordination with the City, reviewing agencies and permitting agencies • Utility coordination and conflict resolution • Potholing of conflicting utilities • Accounting for traffic control during alignment selection all Analyzing alignment alternatives a Providing construction phasing Hydraulic calculations Facility layout is Operator safety and maintenance friendly . Structure aesthetics match surrounding neighborhood One of the key issues on this project will be considering the impacts to Morrison Park and incorporating the park's took and LID themes into the design. 251-12
