Property 2 connected to the regional wastewater treatment system, that project would have a wastewater generation rate of 3 Equivalent Residential Units (ERU), or 750 gallons/day. This is based upon a level of service standard of 250 gallons/ERU/day. Since the North County Wastewater Treatment Plant currently has a remaining capacity of approximately 460,000 gallons/day, the plant can accommodate the additional demand generated by the proposed zoning. 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 3 unit residential development would be anticipated to house approximately 7 people (2.3 X 3). 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 14 (7 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 820,000 cubic yards. The active segment of the landfill has a 1 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 Subject Property 2 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 applies, since the property lies within an AE flood zone, as designated on the Federal Emergency Management Agency's Flood Insurance Rate Map. Consistent with Stormwater Management Sub -Element Policy 1.2 and section 930.07(2) of the county's LDRs, any new buildings constructed within an AE flood zone "must be elevated a minimum of six inches above the base flood level." Since the subject property lies within Flood Zone AE -9, any development on this property must have a minimum finished floor elevation of no less than 9.5 feet above mean sea level. Besides the minimum elevation requirement, on-site retention and discharge standards also apply to this request. With the most intense use of Subject Property 2, the maximum area of impervious surface under the proposed zoning classification will be approximately 14,113 square feet, or 0.324 acres. The estimated runoff volume, based on that amount of impervious surface and the 25 year/24 hour design stone, will be approximately 14,482 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain approximately 2,999 cubic feet of runoff on-site. With the soil characteristics of the subject property, it is estimated that the pre - development runoff rate is 2.84 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 2.84 cubic feet/second, requiring retention of 2,999 cubic feet of runoff for the most intense use of the property, and requiring that all finished floor elevations exceed 9.5 feet above mean sea level. As with all development, a more detailed review will be conducted during the development approval process. March 21, 2000- 97 I
