ATTACHMENT the City has an annual budget for replacing or rehabilitating aging infrastructure and therefore requires a systematic and defensible method for prioritizing both capacity and condition -based improvement projects. The SMP has aided in prioritizing projects on each year's CIP. The SMP references 20 projects for Fiscal Year (FY) 2016/2017 to FY 2020/2021. The current 2018/2019 CIP sewer projects are listed below: • Bristol Street Sewer Main Improvements • Santa Ana Memorial Neighborhoods Sewer Main Improvements • Warner Garnsey Sewer Main Diversion Improvements (project listed in SMP as CIP-CAP-006A) • Willard Neighborhood Sewer Main Improvements Furthermore, the current CIP projects currently under design or construction are listed below: • Citywide Sewer Main Improvements Phase II • Columbine Sewer Main Improvements • Washington Square Neighborhood Sewer Main Improvements • Flower Street Sewer Main Improvements (Washington Street —17th) • Segerstrom/San Lorenzo Sewer List Station In addition to the SMP and CIP sewer system management procedures, the City currently requires sewer monitoring studies for all projects that go through the entitlement process. After submittal and review of these studies by City staff, if the sewer system is found to be deficient, the developer will be required to upsize the portion of the sewer pipe within the frontage of their property. There may be options depending on the condition of the sewer infrastructure for the developers to enter into a joint cost - sharing agreement with the City to cover a portion of the cost for required upsizing that may be done by the City at a later date. If improvements are needed to infrastructure downstream of the project site, the developer may be required to participate and pay into the fair -share agreement currently employed by the City. The fair -share agreement will allow the developer to fund a percentage of the downstream improvement that will be carried out by the City in the future. Therefore, the City has a robust process in place on a project -by -project basisto ensure the sewer system isfunctioning efficiently and will not impact development of any of the Alternative Sites. Water Supply and Distribution The City's Water Utility provides water service within a 27-square-mile service area. The service area includes the City of Santa Ana, and a small neighborhood in the City of Orange, near Tustin Avenue and Fairhaven by the northeast corner of Santa Ana. There are also Irvine Ranch Water District (IRWD) water lines that serve portions of the city. In addition, Orange County Water District (OCWD) provides recycled water service to portions of the city. Metropolitan Water District of Southern California (Metropolitan) also has delivery/conveyance lines that run through the city. The City's water system has a total of nine reservoirs with a storage capacity of 49.3 million gallons, 21 groundwater wells, and seven imported water connections. The 2017 Santa Ana Water Master Plan (WMP) is a multi -year capital improvement program to maintain the City's water utility infrastructure systems in sound operable condition and to meet the level of service expectations of the City over the proposed planning period from 2017/2018 to 2039/2040. The WMP analyzed several components of the City's water system, including groundwaterwell rehabilitation needs, reservoir and pump station status, distribution system upgrade needs, and other miscellaneous improvements. Maintaining groundwater wells has been given the highest priority as groundwater supply is more affordable as compared with water supplies purchased from Metropolitan. The results of the water supply analysis indicated that the City's water system has adequate capacity and distribution 5 Ordinance No. NS-3075
