Transportation As part of the concurrency review process, the applicant has submitted a Traffic Impact Statement (TIS). The county's Traffic Engineering Division has reviewed and approved that TIS. A TIS reports the number of peak hour/peak season/peak direction trips that would be generated by the most intense use of the subject property under the proposed zoning district, and assigns those trips to impacted roads. Impacted roads are defined in the county's LDRs as roadway segments which receive five percent (5%) or more of the project traffic or fifty (50) or more project trips, whichever is less. According to the approved TIS, the existing level of service on impacted roads would not be significantly degraded by the traffic generated by development of 12,600 Square Feet of Retail Commercial use. Water With the proposed zoning, the most intense commercial use of the subject property will result in water consumption at a rate of 3.78 Equivalent Residential Units (ERUs), or 945 gallons/ERU/day. This is based upon a level of service of 250 gallons/ERU/day. Development on the subject property would be served by the South County Reverse Osmosis Plant which currently has sufficient capacity to accommodate the additional demand generated by the proposed rezoning. Wastewater Based upon the most intense use allowed under the proposed zoning, development of the property will have a wastewater generation rate of approximately 3.78 Equivalent Residential Units (ERU), 945 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 West Regional Wastewater Treatment Plant, which currently has sufficient capacity to 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. For a 12,600 square foot commercial development on the subject site, solid waste generation will be approximately 63 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 12,600 square feet of commercial development would be expected to generate 105 cubic yards of waste/year. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 800,000 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. Stormwater Management All developments are reviewed for compliance with county stoimwater 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 Storinwater 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 lie 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 MARCH 12, 2002 -32- X71
