■ The traffic study should include the provision of conceptual layout plans for major intersections within the study area. This is essential to validate the feasibility of implementing improvements. ■ Determination whether streets within site will be private and designed to City of Santa Ana Standards for street design. ■ The study is to include locations of possible signals or signal modifications. PBS&J will then incorporate KOA's traffic report into the EIR's traffic section, cumulative analysis, and alternatives chapter. Utilities and Service Systems The EIR will need to reevaluate the ability of all utilities to serve the project area as a result of the Project revisions and changing regulatory and environmental conditions. Water Supply The EIR will describe the City's water entitlements, treatment plant capacity and conveyance system in the project vicinity. The Orange County Water District's Water Master Plan will also be discussed. Due to the recent changes in the availability of water in California, a new water supply assessment (WSA) will be prepared in compliance with SB 610. Water supply planning under SB 610 requires reviewing and identifying adequate available water supplies necessary to meet the demand generated by the project, as well as the cumulative demand over the next 20 years, under a range of water conditions. Tasks within this effort include such issues as (1) Analysis of past, current, and projected future water demand; (2) Past, current, and projected water supply; (3) Consideration of variability in demand and supply figures based upon hydrologic conditions; (4) Identification of potential water shortages based upon this analysis; (5) Coordination with the local community, as well as other affected agencies; and (6) Consideration of social, geographic, and economic factors of an area. Based on the results of the WSA, the EIR will evaluate whether proposed sources of water are available to serve the project. The effectiveness of programs intended to provide an adequate source of water in dry years, such as aggressive conservation measures, will be qualitatively evaluated based on information provided by the Applicant's and/or City's consultants. If a confirmed source is not available, the EIR will describe the current status of plans for obtaining water, and the process for identifying and securing adequate supply in wet and dry years. The EIR will evaluate the need for water treatment and conveyance infrastructure improvements needed to serve the project site. Wastewater Collection and Treatment The EIR will re -analyze the existing treatment plan service areas. The EIR will describe the existing and planned capacity of the regional wastewater treatment plants, and the location of existing and planned sewage collection system.
