SECTION III ALTERNATIVES We have identified four alternatives available to reduce the high pressure within the Reche Canvon area, including various combinations of pressure reducing station installations, individual pressure regulators, and the creation of a separate pressure zone by construction of a new water storage reservoir, pumping facilities, and related pipelines. The locations of the various alternatives are indicated on Figures 4 through 7. Each of the alternatives is discussed in the following paragraphs: A. ALTERNATIVE NO. 1 Alternative No. 1 consists of installing a pressure reducing station to serve the Mohave area and installing an additional pressure regulator on the customer's side of the water meter for each service within the Matich Development Phase I. The pressure reducing station to serve the Mohave area would be installed on the existing 12" waterline on the westerly side of Reche Canyon Road opposite Placid Lane. Alternative No. 1 is shown on Figure 4. The pressure reducing station on the westerly side of Reche Canyon Road opposite Placid Lane would reduce the pressure to all residences within the Reche Canvon II Pressure Zone located on South Cahuilla Street (Tract 2582), East Sky View Drive (Tract 9536), South Laurelwood Avenue, South Walter Court, and, the high pressure portions of South Mohave Drive and South Cindee Lane (Tract 9839). To maintain a minimum service pressure of 40 psi at the upper elevations of the reduced pressure service area, the pressure reducing station would have to reduce pressures by approximately 65 psi, which would result in a maximum service pressure of approximately 115 psi in the lower areas of the reduced pressure service area. Due to the reduced V
