iJUN is IMM POOK 83 P„u, 7:3 ERU's, if available at the time that his project's impacts occur, or expand county facilities or pay for their expansion to meet the needs of his development, if capacity is no longer available when the impacts of his project occur. With this condition, the utility concurrency test for potable water has been met for the subject request. - Wastewater Wastewater service is not currently available to the subject property by county wastewater systems. Based upon the site development parameters referenced above, wastewater generation for the -site after development consistent with the proposed amendment will be approximately 10.16 Equivalent Residential Units (ERU's), or 2,540 gallons per day. This is based upon the county's adopted level of service standard of 250 gallons per ERU per day. Since no ERU's for wastewater 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 expand county facilities or pay for their expansion to meet the needs of the development. With this condition, the utility concurrency test for wastewater service 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 gross floor area of retail/commercial. development on the subject property -will be approximately 1,065 cubic yards of solid waste per year. This is based upon the county's adopted level of service standard of 2.37 cubic yard 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. - Drainage All development is reviewed for compliance with county stormwater regulations which require on-site retention, preservation of flood plain storage 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 runoff in excess of the pre -development rate. In this case the floodplain storage and minimum floor elevation level of service standards do not apply, since the property is not within a floodplain. Both the on-site retention and discharge standards do apply. With the most intense use of this site, the maximum amount of impervious surface for the proposed request will be approximately 159,390 square feet. The maximum run-off volume, based upon the amount of impervious surface, will be approximately 139,862 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain approximately 125,531 cubic feet of run-off on-site. It is estimated that the pre -development run-off rate is 5.00 cubic feet per second. - Based upon staff's analysis, the drainage level of service standards will be met by limiting off-site discharge to its estimated pre -development rate of 5.00 cubic feet per second and requiring retention of approximately 125,531 cubic feet of run-off for the most intense use of the property.
