2013 Update of Water and Wastewater Impact Fees <br />As was previously mentioned, the overall maximum fee calculations are the sum of various <br />component pieces. So, the utility demands and capital improvements information, shown in <br />Tables 3 and 4, are developed in a similar component fashion. Forecasts are not made in this <br />fee study for local neighborhood water distribution or wastewater collection lines, as these <br />"subdivision- type" improvements are typically funded by the developer rather than the City. <br />Tables 3 and 4 summarize the City's current and projected water and wastewater service <br />demands and existing supply (service) capability by type of facility in both million gallons daily <br />and equivalent LUE terms. The projected growth of the water utility system and service demand <br />reflect an average of 550 new LUEs per year or 5,500 LUEs over the 10 -year planning period. <br />The projected growth of the wastewater utility system and service demand reflect an average of <br />440 new LUEs per year or 4,400 LUEs over the 10 -year planning period. <br />Various "design flow" assumptions for the various types of facilities are shown in the footnotes <br />to the tables and are reflective of what level of service demand each type of facility is intended <br />to meet (i.e. peak day demand, peak hour demand, TCEQ requirements, wet - weather flows, <br />etc.). <br />Current and 10 -year future service demands are compared to the existing service capacity of <br />the various utility components. In some cases such as wastewater interceptor lines, the <br />projected 10 -year demand exceeds existing utility capacity, clearly indicating that additional <br />capacity is needed within the planning period. <br />In several other instances, there is excess capacity available system wide, but not necessarily in <br />the areas where the new service demands are occurring. So, new capital improvements are <br />needed to address that growth. In the case of water supply and treatment, groundwater permit <br />requirements are necessitating the construction of facilities needed late in the planning period to <br />implement the Hays /Caldwell Public Utility Authority groundwater supply project. <br />City of San Marcos, Texas 7 <br />
