Lli facilities can be expressed mathematically in terms of demand units t and.Atandards of service: Needed Improvements = Demand Unit x Service Standard ' Demand Units A "demand unit" is a unit associated with new ' development that generates the need for improvements in public facilities. For purposes of identifying school capital outlay needs, the demand unit most often used is the average number of ' school -age children per residential housing unit, commonly referred to as a student generation rate. Student generation rates have been calculated using 1980 and ' 1990 census data adjusted to reflect conditions in orange County in 1990. The average number of school age children per dwelling unit ' for structures-built between 1975 and 1980 in the South Atlantic region are shown on Table 1. The figures in Table 1 were subsequently reduced by 6.4 ' Percent to reflect the decline in the average number of persons per household in Orange County from 2.50 in 1980 to 2.34 in 1990. The figures were further adjusted to factor out private school ' attendance and reflect the proportion of total students in Orange County that attended public schools in 1990; i.e., 87.6 percent. Specifically, the adjustment was based upon the ratio of the total size of the school age cohort in 1990 to public school enrollment - ' in the same year. Finally, the figures were checked against the enrollment in Orange County public schools, by elementary (49.27 percent), middle (23.98 percent), and high school (26.75 percent) ' categories, and adjusted accordingly. These calculations yielded the set of trial student generation rates shown in Table 2. In order to verify the accuracy of these rates, predicted 1 school membership was calculated by multiplying the above student generation rates of the appropriate housing type by the number of single- family, duplex, garden apartment, etc. units identified in , the 1990 Census. Finally, the results were compared with the actual 1990 membership in schools, and the rates adjusted downward to derive an adjusted set of student generation rates. These ' calculations and the rates derived are shown in Table 3. These overall generation rates were allocated to elementary, ' middle, and high school categories based on the distribution of students in the 1990 school year. The final student generation rates are shown in Table 4. ' Service Standards A "service standard" is generally expressed in terms related ' to land development. For example, a service standard for schools might be expressed in terms of square feet of building [or land) area per student. Standards used in determining need are best ' established within the comprehensive plan. In the absence of such Page - 4 1
