RESOLUTION AUTHORIZING ADDENDUM TO CONTRACT NO. 20429 WITH CLYDE INDUSTRIAL PARK, INC., AUTHORIZING REIMBURSEMENT FOR STORM SEWER CONSTRUCTION NOT TO EXCEED $104,612.

BY COUNCILOR JOHNSON:

     RESOLVED, that the proper city officials are authorized to enter into an addendum to City Contract No. 20429 with Clyde Industrial Park, Inc., to reimburse said company for costs associated with the extension of the city’s storm sewer in the vicinity of the Duluth Heritage Sports Center project in the amount of not to exceed $104,612, payable from Stormwater Capital Improvement Fund 0535, Agency 500, Organization 1905, Object 5533.


STATEMENT OF PURPOSE:  This resolution is to authorize an addendum to the development agreement with Clyde Industrial Park, Inc., for the extension of a storm sewer related to the Duluth Heritage Sports Center.


As part of the plan for the DHSC project, it is necessary to relocate a major storm sewer running through the project; the existing storm sewer is shown as “Existing 32" concrete pipe” on the plan. The original proposal called for the relocation to run down 30th Avenue West to the lower side of the project and then in a westerly direction to connect up to the existing pipe; this is labeled as “Alternative 2" on the plan.


After further engineering review, city staff determined that it would be of benefit to the city if the developer, as part of its project, would extend the new storm sewer another 200 feet down 30th Avenue West before turning to the west and making the connection to the existing pipe. This is shown as “Alternative 1" on the attached plan with the additional construction required shown as a heavy black line and labeled “city share.”


The first benefit of this proposal would be to allow the abandonment of the portion of the old sewer between the proposed connection point and the new connection point, pipe that is known to be very old and is believed to be in deteriorated condition. It would also allow the westerly connection to occur at a much shallower depth than the original proposed location would have allowed, making maintenance (when necessary) much simpler. It would also avoid some potentially contaminated soil.


The city’s cost will be the incremental cost of the additional pipe to be installed in 30th Avenue West. The cost will be paid by the stormwater utility.
