Mountain House Specific Plan III ..........................................................................................................................................................I................ 12.2 Potable Water System 12.2.1 Master Plan Summary The Master Plan provides that the Mountain House community will have an adequate year-round water supply through a service agreement between the Mountain House Community Services District (MHCSD)and Byron Bethany Irrigation District(BBID). The agreement specifies the quantity,cost and conditions of water service. The portions of the Mountain House project area that do not currently lie within the BBID service area shall be annexed to BBID, unless riparian water sources are used for these properties. Specific Plan III will reevaluate the adequacy of the confirmed water supply for the Specific Plan Area in light of any potential or adopted restrictions on water diversion by BBID or the State of California Department of Water Resources(DWR). The Specific Plan shall not be approved unless it can be demonstrated that the confirmed water supply is sufficient to serve the Specific Plan Area through build-out. Future Requirements (MP). If in the future,because of actions or conditions beyond the control of the County or the MHCSD,there is insufficient water for build-out of the community,then measures shall be undertaken to obtain an additional supply of water,to implement more extensive conservation measures, ►. or to revise the Master Plan. 12.2.2 Specific Plan III Description From the September 2000 Final Potable Water System Master Plan(WSMP),the average day water demand with conservation is 8.8 million gallons per day(mgd),with the maximum day demand of 17.1 mgd. Per the Mountain House New Community Master Plan(MHMP),chapter 12, the amount of water to be supplied by BBID to Mountain House is 8.4 mgd(9,413 acre-feet per year). The Master Plan estimated the total average demand to be 8.8 mgd(9,849 acre-feet per year),with the difference to be made up by acquiring riparian water(the rights to some 2.3 mgd(2,600 acre-feet per year) of riparian water within the Mountain House boundary are owned by Trimark).The WSMP estimate of water demand is considered low by the current West Yost and Associates Water System Master Plan Update (August 2003),which ` estimates the average day demand to be 9.1 mgd with the maximum day demand to be 20.0 mgd. While it is apparent that there are varying estimates of the demand,of importance to the community is the ability to adjust supply. 12.2.3 Implementation Measures a. Annexation to BBID(MP).For any area outside the boundaries of BBID that will require delivery of BBID water for urban use as a specific condition of commencement of construction, annexation to Draft 03/14/05 12-3 ...........................................................................................................................................................................
