5 s SOLID WASTE QUANTITIES In January of 1977, the County Administrator's Office conducted a survey, at the request of PBS&J, to determine the rate at which solid waste was incoming to the County's existing central disposal facility. Since scales were not available at the old disposal site, volumetric estimates were used. Available records were assembled from various County, municipal and private sources which indicated the volumetric quantity of solid waste delivered to the disposal site from these sources. Estimated average densities of incoming waste from each of the major user categories were applied to the available volumetric data to provide a reasonably reliable estimate of the average daily and annual rate of incoming solid waste. The results of the survey, shown in Table 1, indicate that during 1976 about 36,000 tons of solid waste were delivered to and disposed of at the County's central disposal site, yielding an average daily incoming rate of solid waste to the facility of about 100 tons per day. The rate at which solid waste will be generated within a given community can be projected on the basis of the community's projected future resident population and an equivalent per capita solid waste generation rate. In April of 1977, the Indian River County Planning Department prepared an updated population projection for each of the 52 enumeration districts within Indian River County. The projections were based on the County's recently adopted (1976) Comprehensive Land Use Plan. These projections conform very closely to previous estimates prepared by the East Central Florida Regional Planning Council in 1974 and with the more recent (1975) population projections prepared by Adley Associates, the County's consulting planners/economists, using the method of "least-squares." The per capita solid waste generation rate is defined as an equivalent unit quantity measurement of solid waste which is theoretically generated by one resident (or capita) over a specified period of time. The per capita figure represents the composite solid waste generation, including household, commercial and industrial post -consumer wastes. It is commonly expressed in terms of "pounds -per -capita -per -day" (lbs/capita/day). The per capita rate has been shown to vary according to a number of factors including the type of development, per capita income levels, and age distribution. A 1971 study conducted by EPA, relates the per capita solid waste generation rate to population density as a measure of the degree of urbanization within a particular community. This technique has proven to be successful in a number of recent studies for estimating and projecting solid waste generation rates and has been applied to Indian River County for this purpose. Also, recent studies by EPA and others suggest that the national per capita solid waste generation rate will increase each year at the rate of approximately 0.1 lb/capita-day as a result of a relatively constant annual increase in the per capita consumer goods useage throughout the United States. This national average annual increase has been incorporated into the solid waste projections for Indian River County. Table 2 contains a summary of the projected total annual and average daily solid waste generation rates for Indian River County from FY 1978 through FY 1994. INITIAL PROJECT COSTS Under the current construction program to provide new facilities to meet Indian River County's immediate and long-term solid waste disposal needs, it will cost an estimated $1,212,000 to plan., design and construct the needed facilities. To date, $415,000 has been spent for the purchase of a 190 -acre parcel of land on which the new sanitary landfill is being constructed. As of July 1, 1977, approximately $228,000 had been spent for planning, design and construction of the new landfill, including the preparation of the first of four 25 -acre areas or segments of the site into which solid waste will be disposed. An additional $469,000 will be required to complete construction of the new landfill and to complete the preparation of the first segment. Also, an estimated $100;000 will be needed to finance the planning, design and construction of two proposed new convenience collection stations which will serve the new landfill. Table 3 presents a complete breakdown of the estimated costs to plan, design and construct the needed facilities under the current construction program. A-4 JAN 181978 e• 8CGK 33 Fa -F 33i
