Book 95 FAGS 59` 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. The subject property is located within the M-1 Drainage Basin. Since the site is located within 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 standard applies, since the property lies within a floodplain. Consistent with Drainage Policy 1.2, "all new buildings shall have the lowest habitable floor elevation no lower than the elevation of the 100 - year flood elevation as shown on the Federal Emergency Management Agency's Flood Insurance Rate Map, or as defined in a more detailed study report." Additionally, section 930.07(2) of the county's LDRs requires that all residential development shall have the lowest floor (including basement) elevated to six inches or more above the base flood level. Since the subject property lies within Flood Zone AE -221 which is a special flood hazard area located within the 100 -year floodplain, any development on this property must have a minimum finished floor elevation of no less than 22.5 feet above mean sea level. Besides the minimum elevation requirement, on-site retention and discharge standards also apply to this request. With the most intense use of this site, the maximum area of impervious surface under the proposed zoning classification will be approximately 11798,156 square feet, or 41.3 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, will be approximately 1,977,972 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain approximately 11478,484 cubic feet of runoff on- site. With the soil characteristics of the subject property,.it is estimated that the pre -development runoff rate is 110.5 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 twenty-four hours, requiring retention of the 11478,484 cubic feet of runoff for the - most intense use of the property, and requiring that all finished floor elevations exceed 22.5 feet above mean sea level. 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 property under the proposed zoning classification indicates that the adopted levels of service would be maintained. The table below illustrates the additional park demand associated with the proposed development of the property and the existing surplus acreage by park type. 31 JUNE 27, 1995
