FEB 2 7 1990 F BOOK i9 FADE -39 Page 11 February 19, 1990 Infrastructure The Infrastructure element of the comprehensive plan addresses potable water, sanitary sewer, solid waste, and drainage. All of these services are currently available to serve the subject site. In fact, demand for both water and sewer will be reduced by the proposed change compared to what it would be if the site were developed as currently designated in the comprehensive plan. Water demand for 1248 residential units X 250 gallons per day equals daily demand of 312,000 gallons. The proposed facility of 1.1 million square feet equals 221 equivalent residential units with a demand of approximately 50,000 daily gallons. The south county R.O. Plant is currently operating at a capacity of 1.6 MGD. This capacity will be increased to 5.3 MGD by 1991. Demand for Sanitary Sewer services is computed at 250 GPD per equivalent residential unit. This results in the same demand as potable water. The West County Regional Wastewater Treatment Plant is presently treating 300,000 gpd. The plant is designed for a capacity of 1.0 MGD. As identified in the comprehensive plan, the solid waste generation rate for residential units is 1.6 waste generation units. For 1248 dwellings the demand would be 1,996 Waste Generation Units. Commercial waste generation rates are 1 unit/100 square feet, resulting in 11,000 WGUs for the 1.1 million square foot facility. The landfill has the capacity to accommodate these wastes without comprehensive plan changes. Offsite drainage for the site is provided by the Indian River Farms Drainage District. Indian River Farms drainage facilities are designed for 3.5" of the total 9.5" rainfall associated with a 24 hour 25 year storm event. The remaining 6" of rainfall must be retained onsite before release into the canals. The project's design for 19.5 acres of onsite retention canals and wetlands will be capable of accommodating the remaining 6" of rainfall. In respect to the peak stage for the 24 hour/25 year storm, there is a concern by SJRWMD that the minimum parking lot and roadway elevations should be 21.7 feet instead of the 21.5 feet proposed by the developer. This would be included among the more detailed analysis of the drainage system as part of the DRI process. Based on these reviews, no changes are needed to the Infrastructure Element. ° Recreation The Recreation Element computes demand for facilities on a population based formula. Since the proposed change is not increasing residential units, there is no increase in demand or required changes to this element. ° Mass Transit Mass Transit is presently not available in Indian River County. Paratransit is available for those with transportation disadvantages. Large scale uses such as the proposed regional mall will serve as attractions which will make mass transit more feasible in the future. Capital Improvements As indicated in the traffic circulation section of this analysis, several roadway and intersection improvements have been identified as required improvements based on the proposed land use change and project. Because of the concurrency requirements of the comprehenive plan, these improvements must be provided concurrent with the project. If the proposed facility is not developed, the roadway improvements would revert to their original timing by the year 2010. 50
