Title
A RESOLUTION AUTHORIZING THE CITY MANAGER TO ADVERTISE FOR BIDS AND TO ENTER INTO A CONTRACT FOR THE NICHOLSON DRIVE STORM SEWER REPAIR PROJECT WITH THE LOWEST AND BEST BIDDER; AND DECLARING AN EMERGENCY.
Executive Summary: The Nicholson Drive Storm Sewer Repair Project will involve the removal and replacement existing concrete storm sewer that has settled within the right-of-way in front of homes along #5643 - #5681 Nicholson Drive in the Williamsburg Colony Subdivision.
Body
Legislative History
None.
Purpose & Explanation
The City of Hudson Engineering and Public Works Departments investigated a failing section of storm sewer located along the easterly side of Nicholson Drive, north of Barlow Road near house #5671 Nicholson Drive. The existing elliptical concrete storm sewers in this vicinity have settled due to the consolidation an underlying layer of soft organic soils. Further investigation has estimated that approximately 350 lineal feet of large diameter, elliptical concrete pipe and two catch basins have also settled. The settling has created a sump in this section of the storm sewer system, which has constricted flows in the pipe during rain events. It has been determined that the best, long term repair solution to remedy this issue includes the removal and resetting of the concrete pipe and replacement of the two catch basins as shown on the attached map. Additional stone bedding, above the City’s standard amount of stone bedding will be installed to eliminate future settling of the storm sewers from occurring again at this location.
The project will be partially funded with the balance of the City of Hudson Storm Sewer Assessment Fund for the Williamsburg Colony Subdivision. This fee was originally collected by the County when this area of Hudson was part of the Township. The funds have been held in escrow for the future use on improvements similar to this project and the current balance of the Assessment Fund is approximately $48,000.
The City Engineering Department is currently working on finalizing the plans and specifications for the improvements. The work is scheduled to be completed by the Fall of 2016.
The estimated project cost of construction plus 10% contingency is approximately $75,000.
Timing Considerations
Following the approval of this Resolution by City Council, the Engineering Department will advertise in the local newspaper and receive bids for this project. Staff will only return to Council if the bids received are in excess of 10% of the Engineer’s Estimate; otherwise the City Manager is authorized to enter into a contract with the lowest and best bidder.

Recommendation
