Overview As requested by the BOCC, attached is the report for the Baypoint Community Wastewater System prepared by Ken Williams of the engineering consulting firm of CH2MHILL. Summary of Findings Service Area/ED Us: The proposed service area is the Baypoint subdivision and Saddlebunch Shores with approximately 320 equivalent dwelling units (EDUs) to be served. Project Description: Wastewater collection will be by a vacuum system. The collected effluent will be treated at a 0.060 million gallons per day, best available technology (BAT) wastewater treatment facility. Project Costs: The total project capital costs, excluding costs to private property owners to decommission existing on-site systems and construct lateral connections to their property lines, will be $3.955 million (January 2003 dollars). Connection Fees and User Charges: Assuming federal, state, and local grant funds of $3.52 million, connection fees are estimated to be approximately $1,360 per EDU and monthly user chargers are $43 per month. No capital expenses would have to be funded in the monthly user charges with the connection fees and current level of grant contributions. Staff Recommendation Approval of the report.

Initially, the Bay Point community wastewater system is proposed to serve the Bay Point Subdivision and Sadd1ebunch Shores, but will not serve the Blue Water RV Park as this park already has a secondary wastewater treatment facility. As recommended in the Momoe County Sanitary Wastewater Master Plan, June 2002 (the Master Plan), the proposed Bay Point WWTP should be capable of being upgraded from 0.060 mgd to 0.075 mgd to be able to accommo- date wastewater flows from the existing Blue Water RV Park WWTP, should this facility opt to connect into the Bay Point BAT WWTP, rather than to upgrade their secondary facility to a BAT facility before July 2010. Current grant funding is as follows: FEMA Federal Grant Funds State Match Grant Funds Total Grant Funds Local Match Funds Total $3,016,848 $502,808 $3,519,656 $502,808 $4,022,464 Cost Estimates Costs used for this analysis are taken from the Master Plan. Master Plan costs were based on September 1998 dollars (ENRl = 5,963). This analysis will use costs, both capital and O&M, projected to January 2003 dollars. This will be done by first updating costs to January 2002 (ENRl = 6,462), and then updating costs to January 2003 (ENRl = 6,624) by escalating these costs at the same rate of inflation that occurred from September 1998 to January 2002 (approximately 2.5% per year). Cost estimates presented herein are order-of-magnitude estimates, as defined by the American Association of Cost Engineers. These estimates are believed to be accurate within the range of 30 percent below to 50 percent above actual costs. Actual costs for any given system would depend on multiple factors, including, but not limited to, actual labor and material costs, market conditions, project scope, and implementation schedule. 1 ENR = Engineering News Record Construction Cost Index Momoe County Board of County Commissioners Page 2 June 18, 2002 Analysis A more in-depth evaluation of projected wastewater flows, preliminary design, and costs estimates beyond the level of effort of the master planning phase have not yet been made, hence, costs from the Master Plan will be used for this analysis. Table 1 summarizes these Master Plan costs (September 1998 dollars) and these same costs projected to January 2003 dollars. With the grant type and amount known, this analysis will review costs for consistency with the grant funding requirements and will also provide a more detailed evaluation of required financial reserves and monthly user charges and fee.

Monroe County Board of County Commissioners Page 3 June 18, 2002 As shown in Table 2, it appears that the FEMA grant funds and State matching grant funds will substantially reduce both the monthly user charges and the connection fees to a level that can be considered as "affordable" charges for a totally new wastewater collection and treatment system. It appears that "the combination of grant funds and connection fees estimated at $1,360 per EDU will completely fund all capital expenses. Therefore, only the annual O&M/R&R and administrative costs must be funded from the monthly user charge. TABLE 2 Summary of Costs and Revenue Sources and Projected Rates, Fees and Charges Revenues Total Project CostS(1) FEMA and State Grant Funds Balance After Grants Connection Fees (320 EDUs @ $1 ,360/EDU) Balance to be Funded from Monthly User Charge $3,955,000 $3,519,656 $435,344 $435,200 $144 Monthly User Charge Debt Service on Capital Balance (6%, 20 yrs) Annual O&M and Administrative CostS(1) Total Wastewater System Annual Cost Total Wastewater System EDUs Monthly User Charge 1 From Table 1 $ 0 $171,800 $171,800 320 $45/EDUlMo The connection fee and the monthly user charge estimated herein should be considered as the best estimate available at this time. As more in-depth evaluations of wastewater flows and preliminary and final design progress, costs may vary, either upward or downward. Obviuosly, if costs are more than used in this analysis, the connection fee and monthly user charge will be more than estimated. Nonetheless, this analysis does show that the grant funds made available to this project should provide" affordable" connection fees and monthly user charges for this project.
