SIMMONS <br />CITY ADMINISTRATOR <br />DATE: May 20, 1997 <br />SUBJECT: Award Bid Drainageway A Storm Sewer Improvements <br />ORIGINATING DEPARTMENT: Public Works <br />SUMMARY: Over the last six months the Public Works Department has been working on formulating and <br />designing improvements within Drainageway A to reduce flooding in the downtown area. Drainageway A is <br />the drainage basin located from approximately Lafayette Street north and from Highway 42 west. The <br />improvements identified, in order to eliminate the drainage poblems, are construction of a large diameter storm <br />sewer from east of Highway 42 to Enrieto Park, and expansion of the detention capabilities at Enrieto Park and <br />Lake Park. The projected expense for the various improvements exceeds $1,000,000. Once completed, the <br />improvements are expected to remove 57 buildings from the flood plain. <br />Given the budget available for storm drainage improvements the Public Works Department has pursued Phase <br />I of the Drainageway A Improvements. Phase I is the storm sewer component which runs from east of Highway <br />42 to Enrieto Park. On April 4 bids were received for the storm sewer portion of the project. Bids were tailored <br />to include an amount of work that would fit the available budget as established at that time, plus alternates for <br />additional work needed to complete the storm sewer to Enrieto Park. The base bid and bid alternates are <br />described as follows: <br />Storm sewer construction from east of Highway 42 to the west side of the Burlington Northern <br />Railroad (BNRR) tracks. <br />Storm sewer construction from the west side of the railroad tracks to the east side of Enrieto <br />Park. <br />Open channel construction and grading east of Highway 42. <br />Bid deduct if Highway 42 is open cut. <br />and bid alternates by bidder are summarized on the attached bid summary. <br />CONTINUED ON NEXT PAGE <br />SUBJECT AGENDA ITEM <br />Award Bid Drainageway A Storm Sewer Improvements <br />6A1 <br />
