PUUK PAf,� �j J - Wastewater Wastewater generation for ±37 units on the subject property will be approximately 37.5 Equivalent Residential Units (ERUs), or 9,375 gallons per day. This is based upon the county's adopted level of service standard of 250 gallons per ERU per day. County Wastewater Service is available to the site from the West County Wastewater Plant. The West County Wastewater Plant has an available capacity of 404,000 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 development or to expand county wastewater facilities or pay for their expansion if capacity is not available at the time of site development. With this condition, the wastewater concurrency test has been 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 approximately 37 units of residential development on the subject site will be approximately 60 waste generation units (WGUs), or 17'7.75 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 of 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. In addition, development proposals will have to meet the discharge requirements of the county Stormwater Management Ordinance. Since the subject property is located within the M-1 Drainage Basin and no discharge rate has been set for this basin, any development on the property will be prohibited from discharging any run-off in excess of the pre -development rate. In this case, the minimum floor elevation level of service standard applies, since the property lies within a floodplain. Consistent with Drainage Policy 1.2, "all new buildings shall have the lowest habitable floor elevation no lower than the elevation of the 100 year flood elevation as shown on the Federal Emergency Management Agency FIRM, or as defined in a more detailed study report." Since the subject property lies within Flood Zone AE, which is a special flood hazard area located within the 100 -year floodplain, any development on this property must have a minimum finished floor elevation of. no less than twenty-two (22) feet above mean sea level. Besides the minimum elevation requirement, on-site retention and discharge level of service standards also apply to this request. With the most intense use of this site, the maximum area of impervious surface for the proposed request will be approximately ±326,700 square feet. The maximum run-off volume, based upon that amount of impervious surface and the 25 year/24 hour design storm, will be ±91,476 cubic feet, using Indian River Farms Water Control District limitations. In order to maintain the county's adopted level of service, the applicant will be required to retain ±338,000 cubic feet of run-off on-site. It is estimated that the pre - development run-off rate is ±15 cubic feet per second. 54
