1' FUTURE PROJECT COSTS If In accordance with the approved construction/operational plans for the new sanitary landfill facility, the net useable land (land on which solid waste will be disposed) consists of approximately 100 acres or about 50 percent of the site's total available land area 090 acres). These 100 acres of "net -useable -land" will be developed in four segments or phases. The first segment, consisting of approximately 25 acres, will be developed (i.e., cleared, filled, graded, etc.) under the 1977-78 construction program. It should provide sufficient landfill space to accommodate the disposal of all solid waste generated within Indian River County over approximately the next 5 years. The remaining three segments will be individually developed, as required, in sequence, according to the approved construction/operational plans to provide continuous solid waste disposal service over the projected useful life of the site. The cost to develop each of the remaining three segments, including clearing and grubbing of the land, filling and grading to prescribed grade elevations, and the construction of perimeter roads, ditches and berms, has been estimated in 1976 dollars as follows: Segment No. 2 — $155,000 Segment No. 3 — 172,000 Segment No. 4 — 190,000 Total Estimated Future Capital Improvement Costs $517,000 Based on the projected solid waste generation rates for Indian River County over the next 17 years, the preparation of Segments 2, 3, and 4 should occur in FY 1983-84, FY 1987-88 and FY 1990-91, respectively. It is anticipated that the capital improvement costs to prepare these three segments will be financed by accumulated net system operating revenues generated during the initial years of operation in prior segments and, if necessary, by short-term financing programs (e.g. tax anticipation notes). PROJECTED OPERATING AND MAINTENANCE (O & M) COSTS The annual O & M costs for Indian River County's new central sanitary landfill are estimated on the basis of its projected resource requirements including manpower, equipment, parts and supplies and utilities. These resource requirements were determined in accordance with the proposed operating schedule for the facility and projected rates of incoming solid waste to the facility. Table 4 contains a breakdown of the projected annual O & M costs for the new sanitary landfill during its initial year of operation (FY 1977-78). To realistically project future O & M costs, an average annual inflation rate of 7 percent has been applied to the projections. The projected annual O & M costs for the new landfill are presented in Table. 5.
