- Wastewater <br />The subject property is serviced by the Central County Wastewater <br />Plant (Gifford). Based upon the most intense use allowed under the <br />Proposed zoning classification, development of the property will <br />have a wastewater generation rate of approximately 154 Equivalent <br />Residential Units (ERU), or 38,500 gallons/day. This is based on <br />the level of service of 250 gallons/ERU/day. The Central County <br />Wastewater Plant currently has a remaining capacity of <br />approximately 537,000 gallons/day and can accommodate the <br />additional wastewater generated by the site under the proposed <br />zoning. <br />- Solid Waste <br />Solid waste service includes pick-up by private operators and <br />disposal at the county landfill. Solid waste generation by a 154 <br />unit residential development on the subject site will be <br />approximately 246 Waste Generation Units (WGU) or 729 cubic yards <br />Of solid waste/year. A WGU is a Waste Generation Unit measurement <br />equivalent to 2.9625 cubic yards of waste/year. <br />According to the county's solid waste regulations, each residential <br />unit generates 1.6 WGU/unit. With the county's adopted level of <br />service standard of 2.37 cubic yards/person/year and the county's <br />average of 2 persons/unit, each WGU is equivalent to 1.25 <br />(2/1.6 = 1.25) and 2.9625 cubic yards of solid waste/year (1.251% <br />2.37). To calculate the total cubic yards of solid waste for the <br />most intense use allowed on the subject property under the proposed <br />.zoning classification, staff utilized the following formula: Total <br />number of WGUs X 1.25 X 2.37 (246 X 1.25 B 2.37 = 729 cubic <br />yards/year). <br />A review of the solid waste capacity for the active segment of the <br />county landfill indicates the availability of more than 900,000 <br />cubic yards. The active segment of the landfill has a 3 year <br />capacity, and the landfill has expansion capacity beyond 2010. <br />Based on staff analysis, it was determined that the county landfill <br />can accommodate the additional solid waste generated by the site <br />under the proposed zoning. <br />- Drainage <br />All developments are reviewed for compliance with county stormwater <br />regulations which require on-site retention, preservation of <br />floodplain storage and minimum finished floor elevations. <br />In <br />addition, development proposals must meet the discharge <br />requirements of the county Stormwater Management Ordinance. The <br />subject property is located within the M-1 Drainage Basin and the <br />Indian River Farms Water Control District (IRFWCD). Since the site <br />is located within the IRFWCD, development on the property will be <br />prohibited from discharging any runoff in excess of 2 inches in a <br />24 hour period, which is the approved IRFWCD discharge rate. <br />The minimum floor elevation level of service standards do not apply <br />in this case, since the property does not lie within a floodplain. <br />However, both the on-site retention and discharge standards do <br />apply. With the most intense use of this site under the proposed <br />zoning, the maximum area of impervious surface will be <br />approximately 469,882 square feet, or 10.78 acres. The maximum <br />runoff volume, based on that amount of impervious surface and the <br />25 Year/24-hour design storm, and given the IRFWCD 2 inch discharge <br />39 <br />DEC ® 81992 RooK 88 F, 947 <br />
