<br /> <br />FY2012 6/15/2011 <br />C.a,.,~ ~a5Nvi3~ <br />B. Methodology and Policy Terms <br />1. There are five "components" involved in calculating what a new dwelling unit will <br />cost the County in terms of providing public facilities. The components are as <br />follows: <br />a. Demand generators -Staff uses the weighted average of single family and multi- <br />family persons per household (2.72 for FY06) and an average number of students <br />per household (0.53 for FY06) to calculate demand generators (number of people <br />and number of students) associated with a new dwelling unit. <br />b. Service levels -Staff calculates existing service levels for each type of facility for <br />which a cash proffer will be accepted. Examples of service levels are: 5.53 acres <br />of park land per 1,000 people, 2.341ibrary books per person, and 99 square feet of <br />space per elementary school child. (Service levels are calculated annually) <br />Gross cost of public facilities -Staff calculates the gross cost of public facilities. <br />The gross cost is used because a credit (described in (d) below) for anticipated <br />future revenues from a new dwelling unit will be applied against the gross cost. <br />For example, to calculate the gross cost of park facilities, multiply the average <br />persons per dwelling unit by the cost per acre of park land plus improvement cost <br />per acre of park land times the acres per capita. <br />d. Credits -Staff calculates a credit to apply against the gross cost for each public <br />facility. Chesterfield has issued and plans to continue to issue general obligation <br />bonds to finance the construction of public facilities. Residents of new <br />developments will pay real estate taxes to the County and a portion of these taxes <br />will go to help retire this debt. So that new dwelling units are not paying twice <br />(once through payment of a cash proffer and again through real estate taxes) a <br />credit is computed. <br />e. Net cost -Staff calculates the net cost per public facility or maximum cash <br />proffer. This is the gross cost [(B)(1)(c)] per public facility minus the applicable <br />credit [(B)(1)(d)] per public facility. <br />2. There must be a relationship between the rezoning itself and the need for a public <br />facility. In order to ensure that money proffered by an applicant is used to fund the <br />public facilities necessitated by the development, geographic service areas or districts <br />are established across the County. <br />Since parks, libraries, and fire stations serve the entire County, the geographic <br />service districts for these facilities are determined to be countywide.
