3.0 4.0 PROJECT APPROACH The project consists of evafuating the existing storm sewer for adequacy and condition. Wade-Trim/Ohio, Inc. believes at this time the existing drainage system should be replaced. This is based on the foltowing reasons: 1. The age of the existing system; 2. The size is inadequate, based on the fact that the existing 18" storm sewer from Eleanor Drive is connecting into a 12" diameter pipe on Columbia Road; and 3. Storm sewers do not exist in front of many properties and therefore do not allow the properties to be tied into the storm drainage system as required by the City. Wade-Trim/Ohio, Inc. design team will provide detailed plans and specifications for the replacement of the storm drainage system. The preliminary plan preparation will consist of an in-depth field survey to locate existing items. Ohio Utility Protection Service (OUPS) will be called in to locate the existing utilities on the site to assist our crew in the location of the underground utilities. We will also review United Survey's information from the videotaping of the existing sanitary sewer. This will help us identify the house connections so conflicts between the sanitary connection and proposed storm system can be addressed in the plans. Wade-Trim/Ohio, Inc. also recommends videotaping the existing storm sewer and the laterals, if the condition of the pipe allows. This will identify the locations of the existing property connections and verify the condition of the laterals. The price for this service has not been added to our fee. We would like to discuss the City's opinion on re-using existing laterals. The detail plan preparation will consist of complete stormwater calculations to locate inlets, outlets, and appropriate size pipe. Future service connections will be provided at Florence Avenue and Eleanor Drive. A review of reusing the roadway catchbasins will be performed to save the City money and minimize the number of trenches across Columbia Road. The roadway, curb, aprons, sidewalk and treelawn will be detailed for replacement where necessary due to the contractor's operation. We anticipate all work will be within the existing right of way.
