Item No. 2 <br /> PC: 4-9-92 <br /> GP-89-11 <br /> Page 4 <br /> PHASING: <br /> The Mountain House new community is proposed to be constructed in four or more phases, with buildout <br /> occurring around 2010. The phasing plan is very preliminary and will change at the Specific Plan stage. <br /> The first phase will develop the northcentral portion of the site and include a small percentage of the town <br /> center. The majority of the first phase will be single-family detached residences. The second phase will <br /> include some additional town center development and much of the area north of Byron Road and <br /> adjacent to Old River. One or both of the golf courses would be constructed in the second phase. The <br /> third phase develops the south central portion of the community, with a significant business park <br /> component included. The last phase develops those portions of the site not currently under the control <br /> of the proponent, which includes all of the area south of Grant Line Road and approximately 200 acres <br /> north of Byron Road. <br /> SUBSEQUENT PLANS: <br /> If this new town General Plan Amendment is approved, submittal of subsequent detailed plans will be <br /> required before any specific development applications are processed. Subsequent plans will include a <br /> Public Services and Facilities Plan,which details specific engineering details for all proposed infrastructure <br /> communitywide. A Public Financing Plan will accompany this document and will be prepared in <br /> cooperation with the County Administrator's Office. Lastly, a Specific Plan will be prepared for the first <br /> phase of development,which will include a detailed land use layout, development standards, and specific <br /> zoning provisions. It is likely that the General Plan will need to be changed as more detailed phasing is <br /> done. It is anticipated that these plans would be approved concurrently, but if not, the Services and <br /> Facilities Plan would be required to be approved first. <br /> LAND USE <br /> AGRICULTURAL ISSUES: <br /> The Mountain House new community is located in an area that is primarily agriculture. Although there <br /> are approximately 30 scattered residences and two dairies (which is also an agricultural use), 4270 acres <br /> of the 4667-acre total are devoted to agricultural enterprises. Seventy-seven percent of the site has been <br /> designated Prime Farmland by the State Farmland Mapping Program. To qualify as Prime Farmland, the <br /> farmland must meet several criteria, including, but not limited to, a dependable water supply, the ability <br /> to hold a specific soil temperature range, retention of an acid-alkali balance, availability of an adequate <br /> water table, allowance of a minimum rooting depth, a condition of infrequent flooding, and specific <br /> permeability. At the time the EIR was prepared, 1040 acres were in alfalfa, 2700 acres were in other <br /> irrigated crops, 160 acres were in irrigated pasture, and 370 acres were in non-irrigated pasture. <br /> The project proponent has stated that there are significant limitations to agricultural productivity on this <br /> site, including the inability to plant any 'bloom' crops, since the prevailing winds prohibit effective <br /> pollination, and the presence of marginal soils (despite its Prime Farmland designation). The proponent <br /> also feels that better prime soils are located more proximate to the City of Tracy. <br />
