CONSULTANT will update the tables and report to incorporate in the analysis the closure and <br /> long-term care cost assessment of the additional active cell 3 for Segment 3. <br /> Task 3: Landfill Depletion Model <br /> Preparation of the FA and FCA(Tasks 1 and 2)typically rely on total permitted capacity of each <br /> cell or segment of the landfill to determine the anticipated closure date for financial planning; <br /> however, in reality,the full capacity of a cell cannot be reached until the subsequent cell is <br /> constructed to a certain elevation to reach the last of the usable air space in the prior cell. <br /> Constructability limits the ability to discretely close one cell before moving to the next cell. The <br /> CONSULTANT will utilize a depletion model for Class 1 waste developed in a previous work <br /> authorization to more accurately determine when the next cell must be online in order to <br /> maximize the capacity in the active cell. The results of the volumetric survey obtained under this <br /> scope of services will be incorporated into an update to the depletion model, and summarized as <br /> an appendix to the Financial Assurance or standalone technical memorandum. <br /> Waste generation will be projected using historical data and adjusted utilizing BEBR population <br /> projections to incrementally increase the volume of waste anticipated in future years. Population <br /> projection growth will be used with straight line interpolation between data points (BEBR <br /> publishes 5-year increments). A Civil 3D surface will be generated,representative of the current <br /> volumetric survey, and incorporated into the existing depletion model to reflect current <br /> conditions. The updated results will be summarized in a technical memorandum to be <br /> incorporated as an appendix to the Financial Assurance report or standalone technical <br /> memorandum. <br /> Deliverables <br /> Task 1 Draft Tables, draft and final reports <br /> Task 2 Draft and final reports <br /> Subtask 2.1 Assurance Form and Escrow Balance and Budget recommendations <br /> Subtask 2.2 Survey (as described in MM&T's proposal), remaining airspace and evaluation of <br /> compaction <br /> Task 3 Summary memorandum <br /> Assumptions <br /> Information to be provided by the COUNTY includes: <br /> • Site access <br /> • Escrow account balances <br /> • The rates and number of dwelling units for each of the transporters <br /> • Available site surveys <br /> • Level of service for each transporter <br /> • Monthly fee for both single family residence and multi-family residences <br /> collected via non-ad valorem assessment <br /> Page 3 of 6 <br />
