Nelson Park Neighborhood Storm Drainage In 1966, a drainage study was completed for the City in an effort to plan for the drainage of future developments and to identify drainage projects for the City to undertake in the near term. During the late 1970's and early 1980's the City invested nearly $20 million in drainage improvements throughout the City. The Nelson Park Neighborhood was identified as a needed future project with residents on nearly every street reporting street and basement flooding; however, this work was never completed. More recently, the City's 2009 Stormwater Master Plan once again identified the Nelson Park Neighborhood as a high priority for drainage, listing it as 2°d out of 46 identified priority areas to address. Based on preliminary designs, the cost estimate is about $4 million with engineering costs included. The project was then put on hold until sufficient funding could be identified. Knowing that the project costs would exceed the City's ability to fund out of current revenue, the City approached the Illinois Environmental Protection Agency (IEPA) and inquired about a low interest loan similar to those the City has recently taken advantage of for high cost sanitary sewer repairs. The IEPA indicated that this project was loan eligible. The City then prepared and submitted a Facilities Plan for the Nelson Park Neighborhood that identified the storm drainage problems, outlined the proposed project to resolve them, and estimated the possible project costs. Upon review of the Facilities Plan, the IEPA has recommended that the City begin the design process with the objective of obtaining a low interest loan to fund construction in 2017. Engineering Services Agreement In 2012, when the City initially began the Nelson Park Project, City staff extended invitations to four local civil engineering firms to interview for the drainage related project. Interviews were held on March 28, 2012. BWC was determined by staff to be the best firm to perform the design work for the Nelson Park Neighborhood Drainage project. The City Council awarded BWC the original preliminary design project in 2012. BWC completed some initial layouts and designs for the neighborhood drainage before the project was put on hold. Staff recommends that BWC continue their design work as identified under the attached agreement. The scope of services includes: 1. Hold meetings with the Nelson Park Neighborhood and other stake holders, including the Decatur Park District, to review and document concerns to be addressed during the design process. 2. Perform a topographical survey of the area. 3. Determine area runoff and drainage patterns in the neighborhood. Design the proposed storm sewer system to handle the projected drainage. 4. Prepare design drawings, construction specifications, and cost estimates. 5. Prepare easement documents. 6. Provide engineering assistance during the bidding process. SCHEDULE: Design work will begin upon Council approval and will be completed in November 2016. The City will be getting loan requirements in place during the design process with the intent to enter into a loan agreement with the IEPA and award a construction contract spring 2017. Page � 2
