Comprehensive Review of S olid W aste Collection and Disposal Options v2.1 100 10/22/12 total property parcel size equal to at least 4 acres to accommodate site access, truck queuing, and turning radius. As an example of one potential option involving regional cooperation, if the Town of Chapel Hill decides to construct a transfer station to accommodate the Town of Carrboro plus their own MSW generation for the next 20 years, the facility should be sized to manage 150 tpd. Based on SCS’s experience, a transfer station sized to handle 150 tpd of MSW will require a building footprint in the 13,500 sf range, situated on a site pad of at least 2.5 acres within a total property parcel size equal to at least 5 acres. With reference to traffic associated with the Town-only scenario, the existing collection vehicles would be expected to visit the facility once per day when collections are occurring. Therefore, incoming residential collection vehicle traffic is estimated to be approximately seven trucks, 2 days per week. Commercial collection vehicle traffic is estimated to be approximately two trucks, 5 days per week. The outgoing transfer trailer vehicle traffic for this scenario is expected to be one or two trailers per day, 5 days per week. If the facility was located on Millhouse Road, this would equate to two to three additional trucks per day. 7.1.3 Estimated Transfer Station Development Costs SCS prepared conceptual budget cost estimates for the construction and operation for both the Town-only and regional transfer station scenarios. The construction cost estimates include costs for siting, permitting, design, building construction, scalehouse and scales, maintenance facilities, utilities, entrance roads, transfer trailer staging area, and ancillary support facilities. The cost estimates do not assign any costs for land acquisition, which reflects an assumption that the facility will be located on an existing Town-owned property. Should the Town need to consider land acquisition costs in this analysis, these preliminary land acquisition costs are described further in Section 11 for the consideration of developing a Town landfill. The cost estimates also do not consider LEED Certified or green building standards. It is expected that meeting LEED Certified or green building standards would increase the cost of constructing a transfer station, but this analysis was not included in this report as only one transfer station on the eastern seaboard was identified by SCS as meeting LEED standards. The cost estimates are based on SCS’s experience working with municipal and private clients throughout the region, and were prepared to provide an order-of-magnitude estimate of the critical aspects of transfer station construction and operation. If the Town were to develop a transfer station under either scenario, a more detailed estimate would need to be prepared based on actual site information. Exhibit 7-3 and Exhibit 7-4 present a summary of the estimated pre- development and capital construction costs to develop a new Town-only or regional transfer station, respectively. For conceptual cost estimating purposes, the capital costs for each scenario are amortized over the 30-year projection period at 4% interest to estimate the yearly allocated capital expenditure costs.
