Based on tbe above assumptions, public facility water demand for the proposed development is estimated to be 15.9 acre-feet per year. as shown in Table 1. bployee Boa.iq Inside water requirements for employee housing were estimated based on 3.5 people per home. and 80 gallons per person per day. Total residential demand is estimated to be about 1.6 acre-feet per year, as shown in Table 1. Bquipllent KainUlllUlce Reqair_nta About 40 golf carts and about ten items of groundskeeping equipment will be used to service and maintain the golf courSe. Washing and other upkeep on these items is estimated to require about 1.5 acre-feet per year. based on one wasb per item per day. and about 50 gallons per wash. Golf Coer.. ad Land.capiq Irdsatioa. Requir_t. The golf course wil1 encompass about 161 acres of formerly-irrigated cropland, of which about 56 acres wi,l1 consist of irrigated fairways. greens and tees. Other landscaping is proposed for an estimated 26 acres. for a total of 82 acres irrigated on tbe new golf course. Figure 2 shows the layout of the golf course featurea. In addition. an estimated five acres of irrigated landacaping is planned around public facilities and roads. and an estimated 0.5 acres of lawns will be irrigated in conjunction with employee housing, for a total of 87.5 acres of irrigation. Irrigation water requirements for turf grass were computed using the modified Blaney-Criddle formula. Research by Blaney and Criddle published in Soil Conservation Service Technical Release 21 revealed a close relationship between climatic factors and evapotranspiration of water by crops. Pub liabed crop coefficients for alfalfa were used to estimate consumptive use by turf grass. Using climatological data for the Great - 5 - ~
