BACKGROUND: The Illinois Department of Natural Resources, Office of Water Resources, requires an annual inspection and report submittal for the Lake Decatur Dam and Sediment Basin Dam. In order to annually obtain objective professional opinions of the condition of the dam, the City has informally rotated the inspection award among several engineering firms. This year, City staff recommends awarding the contract to Homer L. Chastain &Associates, LLP. This will be the initial inspection report for the Sediment Basin Dam. The Illinois Depa.rtment of Natural Resources, the regulating authority for this facility, defines a dam as "all obstructions, walls, embankments, or barriers together with their abutments and appurtenant works, constructed for the purpose of storing or diverting water or creating a „ pool . Construction of this facility designed by Chastain was completed in 2003 as part of the Lake Decatur Dredging Project. Chastain provided an estimate of man hours that is based on their best assessment of the level of effort required to prepare the inspection report. Chastain's proposal indicated that the scope of work may vary depending on the findings of the inspection of the Sediment Basin and how detailed the reports need to be.
