Madison Avenue Street Improvements and Western Water, Water and Sewer Lines

City of Murrieta Madison Avenue Street Improvements. The proposed City of Murrieta (City) Madison Avenue Street Improvements project has been planned to improve accessibility to the South Madison Avenue Business Corridor, as identified in the City’s General Plan 2035 Circulation Element. Consistent with General Plan 2035, which anticipates increased commercial activity throughout the project corridor as part of the City’s economic development goals, the proposed Project would provide improved access to the area through: 1) an alternative north/south circulation option between Jefferson Avenue (to the west) and Monroe Avenue (to the east); and 2) alternative routes to the surrounding Murrieta Hot Springs Road, Jefferson Avenue, Winchester Road, Interstate 215, and Interstate 15 roadway network. In addition, enhanced safety would be provided by improving sight distance lines (following grade changes which adhere to roadway design standards) as well as additional sidewalks and streetlights at existing developed frontage and intersections. Western Water, Water and Sewer Line Improvements. Western Water proposes to update sewer system and water supply infrastructure within the South Madison Avenue Business Corridor in the City. With the exception of an approximately 600-foot segment on Fig Street, the Western Water Madison Avenue Water and Sewer Improvements component (Western Water) proposes to install new sewer system and water system lines in order to improve water supply and sewer infrastructure issues for the District’s service area within the footprint of the City’s proposed Madison Avenue Street Improvements component of the project. Western Water provides water and wastewater services to retail customers and wholesale agencies over a 527-square-mile area in western Riverside County, including the City. The proposed Project would be located within the Murrieta Retail Service Area (a 6.5-square-mile area in the City located to the southwest of I-15). The area is bounded to the west by hills and the Santa Rosa Plateau, to the south by Temecula, to the east by the central and eastern portions of the City, and to the north by the City of Wildomar. In 2006, Western Water took over ownership of the Murrieta Retail Area from the Murrieta County Water District and incorporated it into Western Water. The Murrieta Sewer Division collection systems consist of approximately 38 miles of pipeline ranging from 4inches to 15 inches in diameter of ductile iron, polyvinyl chloride, or vitrified clay material. By length, 88 percent of the pipelines are 8 inches in diameter and 65 percent are polyvinyl chloride. The Murrieta Retail Area water system consists of approximately 2,800 potable water connections served by over 52 miles of potable water pipelines, four potable water tanks, one booster station, and one PRV station. Due to elevation changes, the service area is split into two pressure zones: the 1280 Zone and the 1430 Zone. The 1280 Zone is the larger of the two zones, containing almost 42 miles of water pipelines and serving residential, commercial, and industrial customers. Two tanks, located at the Olga Gordon site on the southern edge of the system, store water for the zone. Both tanks have a low water level of 1,250 feet, a high-water level of 1,282 feet, and a radius of 45 feet, giving them both a capacity of 1.5 million gallons (MG). The 1430 Zone serves the more elevated, northwest portion of the system. It contains almost 11 miles of water pipelines and serves exclusively residential customers. The zone currently has existing storage capable of holding 1.9 MG of potable water at the Grizzly Ridge site. C. Relationship between the Two Project Components Construction of the Western Water component would be entirely coordinated with the Madison Avenue Street Improvements component and integrated into a single construction schedule. With the exception of an approximately 600-foot segment of Fig Street, all of the Western Water sewer and water lines would be installed within the paved portions of the Madison Avenue roadway corridor. Combining the two project components in this manner would substantially reduce construction impacts. Both project components would be subject to the entire list of mitigation measures contained herein.
