According to the county's solid waste regulations, each residential unit generates 1.6 WGU/unit . With the county's adopted level of service standard of 2.37 cubic yards/person/year and the county's average of 2 persons/unit, each WGU is equivalent to 1.25 people (2/1.6 = 1.25) and 2.9625 cubic yards of solid waste/year (1.25 X 2.37). To calculate the total cubic yards of solid waste for the most intense use allowed on the subject property under the proposed zoning classification, staff utilized the following formula: Total number of WGUs X 1.25 X 2.37 (173 X 1.25 X 2.37 = 513 cubic yards/ year). A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 900,000 cubic yards. The active segment of the landfill has a 3 year capacity, and the landfill has expansion capacity beyond 2010. Based on staff analysis, it was determined that the county landfill can accommodate the additional solid waste generated by the site under the proposed zoning. - 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 and the Indian River Farms Water Control District (IRFWCD). Since the site is located within the IRFWCD, development on the property will be prohibited from discharging any runoff in excess of 2 inches in -a 24 hour period, which is the approved IRFWCD discharge rate. The minimum floor elevation level of service standards do not apply in this case, since the property does not lie within a floodplain. However, both the on-site retention and discharge standards do apply. With the most intense use of this siteunder the proposed zoning, the maximum area of impervious surface will be approximately 329,618 square feet, or 7.6 acres. The maximum runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm, and given the IRFWCD 2 inch discharge requirement, will be approximately 354,350 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain approximately 276,000 cubic feet of runoff on-site. With the soils characteristic of the subject property, it is estimated that the pre -development runoff rate is 39 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 2 inches in 24 hours, and requiring retention of 276,000 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 count eation facilities and the projected demand that would result from the most intense use that could occur on the property under the proposed zoning classification indicates that the adopted levels of service would be maintained.
