-2 - <br /> 2. They provided engineering and construction management for our past two extensive dam <br /> repair projects including the Asian carp fish screen. <br /> 3. The fish screen required Hanson to perform hydrologic modeling of Lake Decatur and <br /> the Sangamon River. Since this modeling will be used for EAP development, it reduces <br /> the City's cost for the EAP project. <br /> 4. They have recently modeled the entire Sangamon River basin. Since this modeling will <br /> also be used for EAP development, it further reduces the City's cost for the EAP project. <br /> 5. Their experienced team consists of 5 staff that had worked for OWR. <br /> 6. They have successfully completed 13 EAPs in Illinois that were approved by OWR. <br /> Major tasks that Hanson will perform include: <br /> A. Hydrologic and hydraulic analyses for the (a) sunny day and (b) design Probable <br /> Maximum Flood storm event breach modeling. <br /> B. Submit technical summary memos for the hydrologic and hydraulic modeling to clarify <br /> procedures, assumptions and possible limitations. <br /> C. GIS services for terrain data and breach wave inundation mapping. <br /> D. Emergency responder coordination. <br /> E. Conduct a project orientation meeting in Decatur. <br /> F. Submit a draft EAP document for review and comment by the City, including inundation <br /> mapping and estimated responsibilities. <br /> G. Submit the final EAP document to OWR for approval. <br /> H. Produce 20 bound copies of the final approved EAP document. <br /> POTENTIAL OBJECTION: <br /> None foreseen. <br /> STAFF REFERENCE: <br /> Keith Alexander, Director of Water Management, 217-424-2863 or kalexander@decaturil.gov <br /> Jerry Stevens, Engineering Services Coordinator, 217-424-2833 or jstevens@decaturil.gov <br /> BUDGET/TIME IMPLICATIONS: <br /> This expenditure will come from the Water Lake Capital budget and is estimated to take no <br /> longer than 6 months to complete. <br /> Attachments <br /> cc: Brian Wozniak, Hanson Professional Services Inc. <br /> Paul Mauer, IDNR OWR <br />
