INTRODUCTION AND SUMMARY The Edgemont Water Master Plan Update (EWMPU) includes the Water Infrastructure Analysis Study (WIAS). The objective of the Water Infrastructure Analysis Study is to analyze the existing Box Springs Mutual Water Company (BSMWC) water system and determine the adequacy of the existing system, determine any necessary system improvements and the associated costs of the improvements to comply with the current City of Moreno Valley General Plan and Land Use designations (ultimate development). Presently, the BSMWC facilities cannot meet the City of Moreno Valley minimum fire flow requirements and therefore does not provide adequate fire protection for the approximately 600 existing residential customers and businesses. Further, the water system is aging and deteriorated and in need of replacement and rehabilitation. Two Alternatives for improvements, plus the no action (or no project) alternative, were analyzed to meet the water supply and fire suppression needs of the ultimate development based on water storage facilities, pipeline facilities, pumping facilities and water supply. Alternative No. 1 consists of maintaining the current system operational scheme, with additional water supply from additional groundwater extraction, and upgrading all existing BSMWC facilities (pipelines, reservoir, and hydropneumatic booster station). Alternative No. 2 consists of connecting to the Western Municipal Water District (WMWD) water system for both water supply and fire suppression needs (see Project Description below for a more detailed description). The no project alternative would not adopt or implement the EWMPU and the WIAS would not be utilized to address the inadequacy of the existing system. The proposed improvements are located within the BSMWC service area on the western most end of the City of Moreno Valley and encompasses approximately 430 acres in the Edgemont area (refer to Figure 1, Vicinity Map and Figure 2, Aerial Photograph). Potable water for this portion of the City of Moreno Valley has been provided to residents through the BSMWC. BSMWC is a private shareholder company that was incorporated on June 9th 1920 by landowners to provide water to their lands. Water service for the remaining portion of the City of Moreno Valley is provided by Eastern Municipal Water District (EMWD). Primary water supply is provided via a groundwater well. BSMWC is located within the sphere of influence of WMWD and part of WMWD’s Improvement District “B” as a result of the 1964 agreement to supplement water. This initial study/environmental assessment (IS/EA) has been prepared to assess the potential for any significant environmental effects associated with BSMWC Water Infrastructure Analysis Study. The Lead Agency for this project is the City of Moreno Valley, as BSMWC cannot serve in that capacity pursuant to CEQA. This IS/EA has been prepared pursuant to the California Environmental Quality Act (CEQA, California Public Resources Code Sections 21000 et seq.), and the State CEQA Guidelines (California Code of Regulations Sections 15000 et seq.).
