I - 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 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 zoning district, the maximum area of impervious surface would be approximately 507,038 square feet, or 11.6 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 585,432 cubic feet. In order to maintain the county's adopted level of service, the applicant would be required to retain approximately 444,363 cubic feet of runoff on-site. With the soil characteristics of the subject property, it is estimated that the pre -development runoff rate is 157.05 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 444,363 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 property under the proposed zoning district 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. 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. 50 January 21, 1997 LOS Project (Acres per Demand Surplus Par); Type 1000 population) (Acres -Y Acreage Urban District 5.0 1.34 170.661 Community (north) 3.0 0.80 15.895 Beach 1.,5---- -- - - 0.40 61.598 River 1.5-- 0.40 - 22.595 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.
