7 it as up-to-date and revelant as possible, including new floodplain/floodway boundaries, Edwards Aquifer Recharge Zone boundaries, and thoroughfare and land use amendments that have been approved for developments which have been proposed and/or constructed since 1983. The land use assumptions map is produced in approximately the same color scheme as the Future Land Use map in the Master Plan. The base map is a computer-generated map showing existing streets, selected future thoroughfares, city limits, and ETJ boundary. A photo reduction of this map is included (see page 8). The projections and assumptions given are the minimum necessary to comply with the impact fee law, and are certainly subject to change as conditions warrant. It is hoped that the new 1990 Census data will facilitate inclusion of more comprehensive statistics and projections in the process for future updates of the Impact Fee ordinance. CAPITAL IMPROVEMENTS OR FACILITY EXPANSIONS REQUIRED BY NEW DEVELOPMENT BASED ON LAND USE ASSUMPTIONS FOR A TEN YEAR PERIOD The difference in projected costs for utility extensions between demand occurring from 1990 to 2000, and demand that will occur beyond this ten year planning period, have been derived through a cost allocation methodology. The cost of extending service of the minimum capacity needed to serve the population to the end of the year 2000 is illustrated as follows: Assume that an area of projected growth would require an 8 inch diameter wastewater line, The cost of this 8 inch line would include the pipe, excavation, embedment, manholes, equipment and labor. The entire cost of this line would be included in the computation of the impact fee for the ten year planning period. Suppose population projections for the next twenty-five years, a period often used in planning wastewater service extensions, reveals the ultimate need for a twelve inch line., The cost difference between the construction of the two mains in the nominal cost difference of the two pipes. Therefore, the customers arriving after 2000 would pay only for the oversize of the main (see water and wastewater maps on pages 9 and 10). The cost allocation methodology proposed in this plan requires that the total capacity of the line to be constructed be compared with the capacity required to serve the projected population at the end of the ten year period. If, for example the design capacity of all wastewater utility expansi9ns are estimated to be
