• • 13,000 gallons/day. This is based upon the level of service standard of 250 gallons/FRU/clay. County wastewater service is available to the site from the West Regional Wastewater Treatment Plant, which currently has a remaining capacity of 875,000 gallons/day and can accommodate the additional wastewater generated by the subject request. Solid Waste Solid waste service includes pick-up by private operators and disposal at the county landfill. The county's adopted level of service standard for landfill capacity is 1.97 cubic yards/person/year. With the county's average of approximately 2.3 persons/unit, a 52 unit residential development would be anticipated to house approximately 120 people (2.3 X 52). For the subject request to meet the county's adopted level of service standard of 1.97 cubic yards/person/year, the landfill must have enough capacity to accommodate approximately 237 (120 X 1.97) cubic yards/year. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of over 800,000 cubic yards. The active segment of the landfill has a four 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. Stormwater Management AU 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 he 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 hes within a floodplain. Consistent with Stormwater Management Sub -Element Policy 1.2 the Finished floor elevation of any new buildings constructed within a floodplain must be elevated a minimum of six inches above the base flood level. Since the subject property lies within Flood Zone AE -23, which is a special flood hazard area located within the 100 -year floodplain, any development on the property must have a minimum finished floor elevation of no less than 23.5 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 he approximately 10.5 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 he approximately 466,522 cubic feet In order w maintain the county's adopted level -of -service, the applicant will he required to retain approximately 339,772 cubic feet of runoff on-site. With the soil characteristics of the subject property, the estimated pre -development peak runoff rate is 38.66 cubic feet/second. Based upon staffs 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 466,822 cubic feet of runoff for the most intense use of the property, and requiring that all finished floor elevations exceed 23.5 feet above mean sea level. A, with all development, a more detailed review will be conducted during the development approval pr )cess. April 23, 2002 37 nv Gi
