Populatton projectIons were based on exlstlng data and projectlons for the three-county Metropolitan Statistical Area (MSA). Hays County. the City of San Marcos. and anttclpated bul1dout rates for the two proposed MUDs. Growth projecttons for the Servlce Area were made reasonable wtthtn the context of pro jectfons for the City. the County and the MSA. The planners and market analysts for the Cay and proposed MUDs then projected a sertes of land use bul1dout rates for resldenttalJ commerclal and lndustrlal uses over the 20-year plann1ng per1odJ based on the populatlon project1ons and land use map of the Serv1ce Area. The fifth step was the computation of water demands generated by the projected populatlons and land developments ln the Service Area for 5-year, 10-year and 20-year planning hortzons (years ending 1990, 1995 and 2005). Assumptions for computing water demands per capita and for different land uses were developed on the basis of existing Cay design criteria and accepted engineerlng prlnclples (see attached Letter Report from Freese and Nlchols, Inc.>. Table 3 presents a summary of the water demands, measured ln Living Unlt EQulvalents (LUEs). Demands are shown for each of the two MUDs and for Cay customers tn areas outside the MUDs for the years 1990, 1995 and 2005. Table 3.
