Manson Road Bidge & Watermain Emergency RepairMasterpiece on the Mississippi TO: The Honorable Mayor and City Council Members FROM: Michael C. Van Milligen, City Manager SUBJECT: Manson Road Bridge & Watermain Emergency Repair DATE: September 14, 2011 Dubuque ketil AA- AmedcaCity 1111 I 2007 As a result of the severe storm event that occurred on July 27 and 28, the existing bridge and watermain along Manson Road sustained significant damages due to the historic flooding conditions that occurred. Various portions of the bridge substructure and approaches have been undermined as a result of the high velocity floodwaters. The upstream and downstream embankments on both sides of the bridge have been severely eroded. The velocity of the floodwaters also created a scour hole 14 feet deep on the south side of the bridge which impacted the watermain creek crossing, causing the 8 -inch ductile iron pipe waterline to fail. As of this time, a detailed cost estimate has not been developed for the bridge and watermain repairs. Initial projections are that repair costs could range in the magnitude of $300,000 to $400,000. As a result of the Presidential Declaration (DR- 4018 -IA) for public assistance, FEMA will participate in 75% of the eligible permanent repair work. The City will be responsible for 15% of the cost and the State will be responsible for 10% in funding assistance. In the interest of public safety and welfare, City Engineer Gus Psihoyos recommends City Council approval to initiate an emergency repair project so that the necessary bridge repairs can be made and that the watermain be reconstructed to restore water service and fire protection. Since IIW Engineers & Surveyors are the engineer's of record for both the existing watermain and bridge that were constructed in 2003, it is recommended that IIW be retained to provide consultant engineering design and construction services for the emergency repair project, for an anticipated cost of $50,000. I concur with the recommendation and respectfully request Mayor and City Council approval. Michael C.
