Based on the above analysis, staff determined that Indian River Boulevard and all other impacted roads can accommodate the additional trips without decreasing their existing levels of service. A retail commercial use of 1,825,000 square feet on the subject property will have a water consumption nate and a wastewater generation rate of 5475 Equivalent Residential Units (ERU), or 136,875 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 qty of approy I,g66,000 gallons/day and therefore can accommodate the potable water demand associated with the proposed amendment. The Central County Wastewater Treatment Phut, which serves the subject site, currently has a remaining capacity of approximately 364,000 gallons/day and can accommodate the additionalwastewatergenerated bay the Propos amendment. For a 1,825,000 square foot commercial development on the subject site, solid waste generation will be approximately 18,250 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 nate of one cubic yard for every 1,200 pounds of compacted solid waste generated, the 1,825,000 square feet of commercial development would be expected to generate 30,417 cubic yards of wastelyear. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 840,000 cubic yards. The active segment of the landfill has a 1 year capacity, and the landfill has expansion capacity beyond 2010. Based on staff analysis, it was determined that the county landfill can accommodate the additional solid waste generated by the Proposed amendment. The storruwater management impacts of development are reviewed in detail dining the development approval process. 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 Ord'mance. Since the site is located within the R-4 Drainage Basin, development on the property will be prohibited from discharging any runoff in excess of the pre - development runoff rate. In this case, the minimum floor elevation level of service standard applies, since the property lies within a floodplain. Consistent with Stormwater Management Element Policy 12, "all new buildings shall have the lowest habitable floor elevation no lower than six inches above the elevation of the 100 -year flood elevation as shown on the Federal Emergency Management Agency's Flood Insurance Rate Map, or as defined in a more detailed study report." Since the subject property lies within Flood Zone AE, which is a speaal flood hazard area located within the 100 -year floodplain, any development on this property must have a minimum finished floor elevation of no less than 7.5 feet above mean sea level. Be. P.&. impactsare genes only by residential arses, this proposed amendment will not generate any park use MPacts. Considering the existing land use designation and the anticipated use of the site, the actual increase in land use intensity is lately to be less than typically associated with residential to commerci land use amendments. Currently, the site is designated M-1 units/acre, the county's second highest density land use designation. The M-1 designation allows residential development with densities up to 8. In contrast, the primarily medical office type use anticipated for this site under the proposed land use designation is one of the least intense uses allowed under hand use designation. For t>iese reasons, a major increase in impacts on public facilities and on surrounding areas is not anticipated. MARCH 10, 1998 0 -44-
