Chastain & Associates, LLP for the 2008 Annual Dam Inspections of Lake <br /> Decatur Dam and the Dredging Sediment Storage Facility in Oakley Township for a cost not <br /> to exceed $17,850. <br /> BACKGROUND: <br /> This is an annual inspection required by the State and has previously been approved by City <br /> Council yearly. It is staf�s recommendation to enter into a three year agreement for annual <br /> inspections with Hanson as they are the lead engineers over the City's multiyear dam repair <br /> project. After this three year project is complete, staffwill recommend selecting a different <br /> firm for a follow-up three year inspection project. The purpose in changing inspectors on a <br /> regular basis is to obtain a fresh perspective on the condition of the dam. <br /> The Illinois Department of Natural Resources, Office of Water Resources, requires an annual <br /> inspection of all dams and preparation of an inspection report. The inspection is to be <br /> performed by a qualified licensed engineer. This requirement applies to the Lake Decatur <br /> Dam and the Dredging Sediment Storage Facility in Oakley Township. Hanson has <br /> submitted a proposal to conduct inspections of the facilities and prepare the inspection <br /> reports for 2009, 2010 and 2011, for a fee not to exceed $30,900. <br /> Page � l <br />
