__a..r. Mount Prospect Public Works Department <br />INTEROFFICE MEMORANDUM <br />TO: VILLAGE MANAGER MICHAEL E. JANONIS <br />FROM: VILLAGE ENGINEER <br />DATE: NOVEMBER 13, 2014 <br />SUBJECT: KENSINGTON BUSINESS CENTER POND REHABILITATION PROJECTS <br />ENGINEERING DESIGN RECOMMENDATION PONDS 2, 6, 6A, AND 8 <br />NOT To EXCEED $96,759 <br />Background <br />As part of the Kensington Business Center development in the 1980s, the annexation <br />agreement requires the Village to maintain certain aspects of the 12 retention basins <br />within the park. While the park's management company provides routine maintenance <br />such as algae removal, the Village is responsible for dredging work so that the water <br />depth of the ponds conforms to the design requirements. In addition, the Village <br />maintains and repairs the inflow and outflow structures in each of the ponds and <br />provides bank stabilization. <br />In 1998 a comprehensive study of the condition of all 12 ponds was completed, in part <br />to identify needed repairs and establish a priority ranking for these repairs. To date 7 <br />ponds have been rehabilitated, including in 2002, 2006, 2008, 2011, 2012 and 2013 the <br />Village dredged ponds 4A, 3, 7, 5 & 5A, 4, and 5B respectively. The Village Board <br />awarded contracts for design and construction engineering for each pond to Ciorba <br />Group Inc. (Ciorba). 5 ponds remain to be dredged. <br />The next ponds on the priority list are ponds 2, 6, 6A, and 8. Funds have been allocated <br />for design engineering of these four ponds in the current budget. Only Pond 1 will be <br />remaining. <br />Discussion <br />As permitted by the Qualification Based Selection process, the Village solicited a proposal <br />for engineering services for the design of ponds 2, 6, 6A and 8 from a qualified <br />engineering firm Ciorba, with which the Village has prior experience. Ciorba has <br />previously completed engineering services for pond rehabilitation projects for the Village. <br />In addition, Ciorba has also provided services for the Village on street light, traffic signal <br />and bridge rehabilitation projects. With each of these projects in the Village, their work <br />has been acceptable. Ciorba was asked to submit as part of their proposal the following <br />information: <br />1. A summary of the firms approach to the project. <br />2. A staff hour estimate for major phases of work. <br />3- A maximum_ not -to -exceed fee for dpdgn of the project_ <br />
