NovI � ��`�� PAEE ' �'1 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 70 Residential Units (ERUs), or 10,000 gallons per day. This is based upon the county's adopted level of service standard of 250 gallons per ERU per day. If the subject property were included in the urban service area, county wastewater service would be available for the site from the West County Wastewater Plant. A revi.ew of the West County Wastewater Plant capacity indicates the availability of more than 525,000 gallons per day. Since no ERUs have been reserved. as of the present time, the applicant has - entered into a developer's agreement with the county which states that the developer agrees to pay his impact fees and connect to the county system if capacity is available at the time of site development or to expand county wastewater facilities or pay for 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. Solid 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 M< 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 'Y -: regulations which require on-site retention and minimum finished 'r .�.'.'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 rr4 has been set for. the basin, post development run-off , shall note„ ;rr exceed pre -development runoff. In either case,.', all. new.K:ra, 'construction and improvements shall mitigate the impacts of a 25 year/24 hour storm event. _ _ �` t �"n The subject property is located within the M-1 Drainage Basin and M 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 r. 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.
