cubic yards of solid waste/year (1.25 X 2.37). To calculate the total cubic yards of solid waste for the most intense use allowed on the subject property under the proposed land use amendment, staff utilized the following formula: Total number of WGU's X 1.25 X 2.37 (13,970 X 1.25 X 2.37 = 41,386 cubic yards/year). A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 900,000 cubic yards. The active segment of the landfill has a 2 year capacity, and the landfill has expansion capacity beyond 2010. Based on staff analysis, it was determined that the county landfill can accommodate the additional solid waste. - Drainage All developments are reviewed for compliance with county stormwater regulations which require on-site retention, preservation of floodplain storage and minimum finished floor elevations. In addition, development proposals must meet the discharge requirements of the county Stormwater Management Ordinance. The subject property is located within the M-1 Drainage Basin and the Indian River Farms Water Control District (IRFWCD). Since the site is located within the IRFWCD, development on the property will be prohibited from discharging any runoff in excess of two inches in a 24 hour period, which is the approved IRFWCD discharge rate. In this case, the minimum floor elevation level of service standards do not apply, since the subject property does not lie within a floodplain. However, both the on-site retention and discharge standards do apply to this request. Under the proposed amendment, the maximum area of impervious surface will be approximately 4,824,500 square feet, or 111 acres. The maximum runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm, will be approximately 4.4 million cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain approximately 3.4 million cubic feet of runoff on-site. With the soil characteristics of the subject property, the pre -development runoff rate is estimated to be 88.7 cubic feet/second. Based upon staff's analysis, the drainage level of service standards will be met by limiting off-site discharge to the IRFWCD's maximum discharge rate of two inches in 24 hours, and requiring retention of 3.4 million cubic feet of runoff for the most intense use of the property. As with all development, a more detailed review will be conducted during the development approval process. - Recreation Recreation concurrency requirements apply only to residential development. Therefore, this comprehensive plan amendment and rezoning request is not required to satisfy recreation concurrency requirements. The concurrency requirements for drainage, solid waste, water, wastewater, and parks have been met for the proposed amendment. Incorporating the referenced road improvements into the associated DRI Development Order will satisfy the concurrency test for the subject request. 41 rVA PAGE 8,88 MAR ®11994 bOUK,
