The report recommended installing a 24-inch interceptor sewer beginning at the District's existing Hickory Point Pump Station and extending northwesterly approximately 5,000 feet to a location north of Hickory Point Road and east of Oakland Avenue. From this point a 10-inch trunk sewer would extend north to serve the Village of Forsyth and a 15-inch trunk sewer would extend westerly to serve fiiture development in the City (refer to attached Project Plan - Phase I). The 15-inch trunk sewer will be the City's responsibility to design, construct and maintain because it primarily serves the City. The 24-inch and 15-inch sewers will be the primary wastewater collection lines serving the far northwest area of the City. The route of the sewers shown in the report is based on general information and cannot be used to build the new sewers. A final design must be completed by an engineer to show the exact location of the new sewers. The final design is used to obtain bids from contractors and construct the new sewers. In the final design process, the engineer obtains detailed information about an area that includes existing underground utilities, the area's topography and other existing improvements (i.e. streets, buildings, storm sewers, sidewalks, etc.). This information is used to determine the route that avoids conflicts with other improvements, provides the maximum level of service and is cost effective. The route determined in the final design may vary from the general route shown in the � preliminary study. The City and the District agreed in the May, 1995 letter to consider an Intergovernmental Cooperation Agreement (ICA) for the design and construction of the project if the Facility Plan was amended and the Archaeological Reconnaissance Survey was satisfactory to both parties. In City staffs opinion, these two conditions have been satisfied. In addition, the District has conducted the required public meeting to obtain public comment about the project. Copies of the letters in support of the project are included as exhibits in the ICA (refer to attached copy of the ICA). At the public meeting, there was support for the project and the needs it is intended to serve. City staff and the District have prepared an ICA for the design and construction of the City's trunk sewer in conjunction with of their interceptor sewer project. A copy of the ICA is attached. The ICA contains a provision for the City to terminate the ICA following the completion of the final design, if the City should decide to not proceed with the construction of its 15-inch � sewer. The estimated design cost for the City's 15-inch sewer is $19,500. If the City decides not �� to proceed with the construction of its sewer, it will have to reimburse the District for the engineering design expenses. The estimated cost for construction including construction supervision, legal fees and right-of-way costs is $231,000. Final costs will be based on actual costs of construction and services. It is expected that the project will be funded through a loan obtained by the District from the State of Illinois Water Pollution Control Revolving Fund. The loan repayment period is 20 years and the annual interest rate for this type of loan has historically been about 3.0 percent. The City's annual reimbursement to the District for the City's share of the loan repayments would be appro�mately $16,200 per year for 20 years. The City would have to pay the District an estimated $5,000 for non-loan eligible expenses at the completion of the project. The improvements are, at this time, planned to be constructed in the District's 1998-1999 fiscal year beginning May 1 and ending April 30 of the following year.
