A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 820,000 cubic yards. The active segment of the landfill has a 2 year capacity, and the landfill has expansion capacity beyond 2010. Based on the analysis, staff determined that the county landfill can accommodate the additional solid waste generated by the site under the proposed zoning district. 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. Since the site is located within the M-1 Drainage Basin and the Indian River Farms Water Control District (IRFWCD), development on the property will be prohibited from discharging any runoff in excess of 2 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 property does not lie within a floodplain. However, both the on-site retention and discharge standards apply. With the most intense use of this site under the proposed amendment, the maximum area of impervious surface would be approximately 670,824 square feet, or 15.4 acres. The maximum runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm, and given the IRFWCD 2 inch discharge requirement, would be approximately 595,508 cubic feet. In order to maintain the county's adopted level of service, the applicant would be required to retain approximately 436,036 cubic feet of runoff on-site. With the soil characteristics of the subject property, it is estimated that the pre -development runoff rate is 63.12 cubic feettsecond. Based upon the County Engineering Division's analysis, the drainage level of service standard would be met by limiting off-site discharge to the IRFWCD's maximum discharge rate of 2 inches in 24 hours, and requiring retention of the 436,036 cubic feet of runoff for the most intense use of the property- As roperty As with all development, a more detailed drainage review will be conducted during the development approval process. A review of county recreation facilities and the projected demand that would result from the most intense development that could occur on the property under the proposed zoning district indicates that the adopted levels of service would be maintained. The following table illustrates the additional park demand associated with the proposed development of the property and the existing surplus park acreage. PARK INFORMATION LOS (Acres per 1,000 Population) Project Demand (Acres) Surplus Park Acreage 4.0 1.62 232 Based upon the analysis conducted, staff has determined that all concurrency -mandated facilities, including drainage, roads, solid waste, recreation, water, and wastewater, have adequate capacity to accommodate the most intense use of the subject property under the proposed zoning district. Therefore, the concurrency test has been satisfied for the subject request. NOVEMBER 16, 1999 BOOK ill PAGE -7 7
