F' BOOK 103 FACE587 - Wastewater Based upon the most intense use allowed under the proposed zoning, development of the property will have a wastewater generation rate of approximately 236 Equivalent Residential Units (ERU), or 59,000 gallons/day. This is based upon the level of service standard of 250 gallons/ERU/day. County wastewater service is available to the site from the Central Regional Wastewater Treatment Plant, which currently has a remaining capacity of more than 1,300,000 gallons/day and can accommodate the additional wastewater generated by the subject request. - -Solid Waste — Solid waste service includes pick-up by private operators and disposal at the county landfill. The county's adopted level of service standard for landfill capacity is 1.97 cubic yards/person/ year. With the county's average of approximately 2.3 persons/unit, a 236 unit residential development would be anticipated to house approximately 543 people (2.3 X 236). For the subject request to meet the county's adopted level of service standard of 1.97 cubic yards/person/year, the landfill must have enough capacity to accommodate approximately 1,070 (543 X 1.97) cubic yards/year. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 830,000 cubic yards. The active segment of the landfill has a 2 year capacity, and the landfill has expansion capacity beyond 2010. Based on the analysis, staff determined that the county landfill can accommodate the additional solid waste generated by the site under the proposed zoning district. - 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. Any development on the subject property will be prohibited from discharging any runoff in excess of the pre -development rate. In this case, the minimum floor elevation level of service standard does not apply, since the property does not He within a floodplain. On-site retention and discharge standards, however, do apply to this request. With the most intense use of this site, the maximum area of impervious surface under the proposed zoning classification will be approximately 20.65 acres. The estimated runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm, will be approximately 882,350 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain approximately 241,930 cubic feet of runoff on-site. With the soil characteristics of the subject property, it is estimated that the pre -development runoff rate is 149.61 cubic feet/second. Based upon staffs analysis, the drainage level of service standards will be met by limiting off-site discharge to its pre -development rate of 149.61 cubic feettsecond, and requiring retention of 241,930 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 county recreation facilities and the projected demand that would result from the most intense development that could occur on the property under the proposed zoning district indicates that the adopted levels of service would be maintained. The following table illustrates the additional park demand associated with the proposed development of the property and the existing surplus park acreage. MARCH 99 1999 M.
