MAY 2-1 BOOK 83 pg E.3 - Solid Waste Solid waste service includes pickup by private operators and disposal at the county landfill. Solid waste generation by an 80,000 square foot commercial development on the subject site will be approximately 1,764 cubic yards of solid waste 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. Based upon staff analysis, it was determined that the county landfill can accommodate the additional solid waste. - Drainage All development is 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 have to meet the discharge requirements of the county Stormwater Management Ordinance. Since the subject property is located within the R-7 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 area of impervious surface for the proposed request will be approximately 264,000 square feet. The maximum run-off volume, based upon the amount of impervious surface, will be 231,656 cubic feet. In order to maintain the county's adopted level of service, the applicant will be required to retain 207,920 cubic feet of run- off on-site. With the sandy soils characteristic of the property, it is estimated that the pre -development runoff rate is 16.8 cubic feet per second. Based upon staff's analysis, the drainage level of service standards will be met by limiting offsite discharge to its pre - development rate of 16.8 cubic feet per second and requiring retention of the 207,902 cubic feet of runoff for the most intense use of the property. Recreation Concurrency for recreation is not applicable for this request as the request is for commercial development, and recreation levels of .{service apply only to residential development. Compatibility with the Surrounding Areas Compatibility with the surrounding area is not a major concern for this property. Although the proposed request is for an expansion !.of the commercial land use designation, it is anticipated that commercial development on the subject site will maintain compatibility with surrounding areas in two ways. The first will ;.be through buffering. Since the applicant is requesting a. ;'comprehensive plan amendment'and rezoning for only a portion of a =20.65 acre parcel of land, there will be a two hundred (200) foot buffer of RM -6 zoned property located between the proposed request ,and the single family residential area west of 135th Street. The second means., of ensuring compatibility will be through landscaping. At the time of development review, this site will be required to meet the county's landscaping requirements and to provide adequate buffering between any commercial development and adjacent residentially designated properties. Based upon the analysis performed on the subject property, staff feels that the requested -commercial zoning would be compatible with the surrounding area. 22
