• • • Infrastructure costs and potential impact to taxpayers Water and Sanitary Sewer The proposed development will require the extension of the City's trunk water and sanitary sewer lines from Main Street to the project site. The existing trunk facilities, installed in 1998, were designed to accommodate the potential demand from the development site. The developer will be responsible for 100% of the sewer and water costs associated with the extension of the utilities except for pipe over sizing and over depth required to serve property outside of the project limits. Additionally, the developer will be responsible for trunk utility area and unit charges. These charges were established to equitably distribute the costs of trunk utility infrastructure, i.e., wells, water towers, lift stations, oversized pipe etc. When over sizing or deeper pipes are required to be installed to service areas outside of the development a credit will be provided. Area and Unit charges are reviewed and updated annually based on the ENR Construction Cost Index. The charges for 2005, based are as follows: Sanitary Sewer Area Charge Sanitary Sewer Unit Charge Watermain Area Charge Watermain Unit Charge $2,520.00 acre $1,095.00 per unit $2,690 00 per acre $1,765.00 per unit In general the 363 acre site will generate approximately $1,891,230 in area charges based on the 2005 fee schedule (the actual amount will be dependent on upland area and the development year). Unit charges vary depending on use. A single family home represents 1 unit. Based on 2005 rates and the proposed unit total (1,250) the residential portion of the development would generate $3,575,000 in trunk utility unit fees. Unit fees on commercial development would be in addition to this amount. The estimated trunk utility charges should cover any city credit for over sizing or over depth as well as contribute to debt retirement of infrastructure costs previously incurred. There is no impact on taxpayers for sanitary sewer and water infrastructure. Surface Water Management The proposed development will require the installation of storm sewer and water quality ponding. The developer is responsible for 100% of the cost of such improvements. The City has established a Surface Water Management Charge that covers administration, Surface Water Management Planning, Subwatershed Hydrologic Planning, Subwatershed trunk lines, ponding and water quality projects. The charges for 2005 are based on upland area and are as follows: Single Family Residential $0.1 per square foot Multiple Family Residential $0.137 per sq. ft. Commercial /Industrial $0.151 per sq. ft. Page 4
