r MAY ® 5 N92 BOOK '�' �'P��E►��: the expansion if capacity is not available at the time of site development. With these conditions, the utility concurrency test will be met for the subject request. -Solid Waste Solid waste service includes pickup by private operators and disposal at the county landfill. Stolid waste generation by 40 dwelling units on the subject site will be approximately 64 waste generation units or 193 cubic yards of solid waste per year. This is based upon the level of service standard of 2.37 cubic yards per capita per year. A review of the solid waste -capacity for the active segment for the county landfill indicates the availability of more than 900,000 cubic yards. The active segment of the landfill has a 4 year capacity, and the landfill has expansion capacity beyond 2010. Based upon staff analysis, it was determined that the county landfill can accommodate the additional solid waste. -Drainage All developments are reviewed for compliance with county stormwater regulations which require on-site retention and minimum finished floor elevations. As stated in Drainage Policy 1.1, the drainage level of service standard is that post development run-off shall not exceed the maximum discharge rate of the applicable drainage basin if a rate has been set for the basin. If no discharge rate has been set for the basin, post development run-off shall +not exceed pre -development runoff. In either case, all new construction and improvements shall mitigate the impacts of a 25 year/24 hour storm event. The subject property is located within the M-1 Drainage Basin and in the Indian River Farms Water Control District. No discharge rate has been set for the M-1 drainage basin; however, there is a standard drainage discharge rate of two inches in 24 hours in the Indian River Farms Water Control District. With the most intense use of this site, the maximum area of impervious surface for the proposed request will be approximately 250,000 square feet. The maximum increase in run-off volume above the predevelopment runoff rate, based upon the amount of impervious surface, will be 82,000 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain 960,000 cubic feet of new and existing run-off on-site. In this case, minimum finished floor elevation level of service standards are applicable, since the property is within floodplain AE. According to Drainage Policy 1.2, the minimum finished floor elevation level of service standard is that all new buildings will have the lowest habitable floor elevation not lower than the elevation of the 100 -year flood elevation as shown on the Federal Emergency Management Agency Flood Insurance Rating Maps (FIRM), or as defined in a more detailed study report. The minimum finished floor elevation for floodplain AE for this site is 22 feet as shown on the Federal Emergency Management Agency FIRM. In order to maintain the county's adopted level of service for minimum finished floor elevations, the applicant will be required to construct all buildings at or above an elevation of at least 22 feet above mean sea level. Based upon staff's analysis, the drainage level of service standards will be met by limiting off-site discharge to its pre - development rate of 11 cubic feet per second, requiring retention Of 960,000 cubic feet of run-off for the most intensive use of the Property, and maintaining a minimum finished floor elevation of 22 feet. 72
