BACKGROUND: Residents in the neighborhood lying generally north of Hickorywood Drive and east of Martin Luther King, Jr. Drive (refer to attached location map) have complained in the past about flooding problems from the overtopping of MLK from heavy storm runoff. This flooding has been the result of blockages to the intake structure on the east side of MLK from cornstalks or other field crop residue. The problem is compounded because the twin 48-inch diameter storm sewer pipes beginning at MLK and ending at Crescent Drive empty into a single 48-inch diameter sewer pipe. At the time that MLK was improved, the extension of the 48-inch pipes beyond Crescent Drive was not completed because of easement issues which could not be resolved in a timely manner. The design was recently completed by staff and the necessary easements obtained. The project will include the installation of twin 48-inch pipes, grade the area, and riprap the outfall. The project plans and specifications were prepared by City staff. The project was advertised June 20, 2001, and bids were opened on July 9, 2001. The results for the letting are as follows:
