the county landfill can accommodate the additional solid waste generated by the site under the proposed zoning district. 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. 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 two inches in a twenty-four 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 he within a floodplain. However, both the on-site retention and discharge standards apply. With the most intense use of this site under the proposed zoning district, the maximum area of impervious surface would be approximately ±23.4 acres. The maximum runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm, and given the IRFWCD two inch discharge requirement, would be approximately 1,026,206 cubic feet. In order to maintain the county's adopted level of service, the applicant would be required to retain approximately 743,066 cubic feet of runoff on-site. With the soil characteristics of the subject property, it is estimated that the pre -development runoff rate is 80.98 cubic feet/second. Based upon staff's analysis, the drainage level of service standard would be met by limiting off-site discharge to the IRFWCD's maximum discharge rate of two inches in twenty-four hours, and requiring retention of the 743,066 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 A review of county recreation facilities and the projected demand that would result from the most intense development that could occur on the subject property under the proposed zoning district indicates that the adopted level 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.
