HILL MEMORANDUM <br /> DATE: January 11, 2010 <br /> TO: Honorable Mayor and City Council Members <br /> Sue Iverson, Acting City Administrator <br /> FROM: Kristine Giga, Civil Engineer <br /> Michelle Olson, Parks and Recreation Manager <br /> SUBJECT: County Road E/TH 51 Bridge- Municipal Agreement Program Update <br /> Background <br /> At the August 31, 2009 Regular City Council Meeting, staff received direction from the <br /> City Council to prepare an application for funding through Mn/DOT's 2009 Municipal <br /> Agreement Program for modifications to the existing County Road E bridge over Snelling <br /> Avenue (TH51). The Municipal Agreement Program Application was submitted on <br /> September 28, 2009. Staff received comments on this application on December 15, 2009. <br /> The comments received identified that Mn/DOT is considering this bridge for an <br /> improvement project in FY 2015. Because the bridge is considered functionally obsolete, <br /> which means the geometric layout does not meet current standards, this bridge would be <br /> reconstructed. <br /> City staff and Kimley-Horn representatives met with Mn/DOT on December 29, 2009 to <br /> discuss the comments and options on moving forward with improvements to this bridge. <br /> This bridge had not been programmed or identified for replacement in the next five to ten <br /> years. However, the City's continued efforts in seeking assistance to improve the existing <br /> conditions of the bridge have highlighted the existing bridge deficiencies, causing the <br /> Mn/DOT bridge maintenance office to move up improvements to this bridge to FY 2015. <br /> The comments received from Mn/DOT bridge maintenance staff indicated that the scope of <br /> our project would need to be modified due to the condition of the existing concrete. These <br /> modifications anticipate the need for additional deck repairs once the bridge overlay is <br /> removed. In 1993, when Mn/DOT placed the current overlay, they encountered some deck <br /> deterioration. At that time, they decided not to make repairs to the structural bridge deck <br /> and simply cover the deck with an overlay. The scope of our current project anticipated <br /> doing the same, removing the overlay and replacing it with modifications to the sidewalks. <br /> Mn/DOT recommends the City add the repair of the structural deck to our project. This <br /> would include adding quantities for partial and full deck thickness repair in the event that <br /> we encounter deteriorated areas once the current overlay is removed. <br /> \\Metro-inet.us�ardenhills\PR&PW\Parks\Memos\Council Memos\011110 Municipal Agreement Update.doc <br />
