ADDITIONAL INFORMATION:

On May 22, 2006, under Roll Call No. 06-977, the City Council approved a preconstruction agreement with Iowa DOT for Keo Way (Birds Run) Phase 2 Storm Sewer related to I-235, where the City will reimburse Iowa DOT an estimated 57% of the storm sewer cost, 100% for any enhanced storm capacity, and 100% of sanitary sewer cost. The repayment will begin in FY 2007-08. As part of this agreement, change orders exceeding $25,000 in additional City contribution shall be approved by the Des Moines City Council.

Change Order No. 24 is for additional cost to furnish and install 200 feet of new 6” PVC pipe at 1300 Keo Way to a connection point in the sanitary sewer pipe in Oakridge Drive. The existing sanitary sewer service was connected to the storm sewer. Part of the existing paving and sidewalk was removed and replaced for the installation of the 6-inch sanitary service. The change order has been reviewed by the City’s representative, Veenstra and Kimm, Inc., and found to be reasonable. The City’s share is 100% because the City is responsible for the sanitary sewer improvements as part of the agreement. The work is necessary to restore service to the sanitary sewer instead of the storm sewer. The total change order is for $44,975.
