48 All parcels that already have access to water and/or sewer on the maps are identified in a black crosshatch; some of these parcels are currently connected to OWASA's system and some are not. The Proposed Utility District would extend water and sewer to all parcels within the purple boundary. The newly Proposed Utility District almost doubles the amount of sewer that would need to be installed from what was proposed in May 2012. This expanded area increased the lineal feet of sewer extension required from 3.6 miles to 6.8 miles and added 4.4 miles of water main extension. The conceptual layouts for sewer and water are based on the parcel boundaries as they are currently configured and whether or not a structure or multiple structures are currently located on a parcel was not considered. The Proposed Utility District includes all parcels and the cost per parcel in some areas will be much greater than others. Exhibit 5 (High Cost Areas) identifies 5 areas where the cost of new water and/or sewer infrastructure/parcel will be the highest. If the high cost areas are removed until additional development occurs in the Proposed Utility District the initial cost of the Utility District would go from $17.6 million to $13.4 million. This represents a 24% decrease in the initial cost, which could be the final phase of the Utility District, and would eliminate water and/or sewer service to 22 parcels. The cost for the High Cost Areas is outlined below: Proposed Utility District Less High Cost Areas Total Water Cost Less High Cost Areas Total Overall Cost for Water $ 5,991,251 Minus High Cost Areas for Water $ 1,826,331 Total Water $ 4,164,920 Total Sewer Cost Minus High Cost Areas Total Overall CostforSewer $ 11,688,811 Minus High Cost Areas for Sewer $ 2,465,767 Total Sewer $ 9,223,044 Total Water& Sewer Cost Minus High Cost Areas $ 13,387,964 12
