Water A retail commercial use of 21,000 square feet on the subject property will have a water consumption rate of 6.3 Equivalent Residential Units (ERU), or 1,575 gallons/day. This is based upon a level -of - service standard of 250 gallons/ERU/day. Water lines extend to the site from the South County Reverse Osmosis Plant which currently has a remaining capacity of approximately 1,518,338 gallons/day and therefore can accommodate the potable water demand associated with the proposed amendment. P. Wastewater The subject property is serviced by the Central Regional Wastewater Treatment Plant. Based upon the most intense use allowed under the proposed amendment, development of the property will have a wastewater generation rate of 6.3 Equivalent Residential Units (ERU), or 1,575 gallons/day. This is based upon the level -of -service standard of 250 gallons/ERU/day. The Central Regional Wastewater Treatment Plant currently has a remaining capacity of approximately 364,233 gallons/day and can accommodate the additional wastewater generated by the proposed amendment. 01 Solid Waste Solid waste service includes pick-up by private operators and disposal at the county landfill. For a 21,000 square foot commercial development on the subject site, solid waste generation will be approximately 105 waste generation units (WGU) annually. A WGU is a Waste Generation Unit Measurement equivalent to one ton (2,000 pounds) of solid waste. Using the accepted conversion rate of one cubic yard for every 1,200 pounds of compacted solid waste generated, the 21,000 square feet of commercial development would be expected to generate 175 cubic yards of wastelyear. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of 840,214 cubic yards. The active segment of the landfill has a two-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 land use designation. 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 site is located within the R-4 Drainage Basin. In this case, the minimum floor elevation level -of -service standards do not apply, since the property does not he within a floodplain. However, both the on-site retention and discharge standards apply. With the most intense use of this site under the proposed amendment, the maximum area of impervious surface would be approximately 36,590 square feet, or 0.84 acres. The maximum runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm would be approximately 49,169 cubic feet. In order to maintain the county's adopted level -of -service, the applicant would be required to retain approximately 19,225 cubic feet of runoff on-site. With the soil characteristics of the subject property, the estimated pre -development runoff rate is 6.69 cubic feettsecond. Based upon staffs analysis, the drainage level -of -service standards will be met by requiring retention of the 19,225 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. Apri128, 1998 42 1
