� In 1993, approximately 1 S percent of the structural deck area was deteriorated. That area of deterioration has likely increased since 1993, however it is very difficult to diagnose the amount of deck repairs that are necessary until the current overlay is removed. Adding these deck repairs to the proposed improvements, would increase the overall cost of the proj ect around $100,000. Since the potential redeck of the bridge could trigger other necessary repairs, the City could be liable for additional repair costs that are not included in the municipal agreement funding. Mn/DOT representatives present at the December 29, 2009 meeting stated that the City's proposed improvements to the existing bridge would delay any upcoming bridge improvement proj ects to an undetermined date in the future. Discussion Staff has identified the following options for the City Council's consideration about future improvements to the County Road E bridge over T.H. 51. Staff is requesting action on Option 1 only. OPTION 1: Continue to pursue the Municipal Agreement by adjusting the scope of the project in response to the comments provided by Mn/DOT. PROS CONS The proj ect could take place in 2010 (State FY When the improvements take place, if other 2011). deficiencies are identified, the City will be liable for the additional costs. The money awarded through this agreement does not include approach sidewalks or an attached sidewalk from Snelling Avenue. The sidewalk will be a substandard design (5 feet) and will not meet multi-use trail design standards . This is a temporary fix that will delay future replacement of the bridge. OPTION 2: Pursue the stand alone bridge option if the STP Federal Application is successful. (Met Council will be meeting February 17, 2010 to determine which proj ects will receive funding.) PROS CONS Could be constructed in 2012 (Federal FY 2013) The City must wait until 2012. Meets all shared use pathway standards. Local costs- federal grants have a 20% local match funding requirement Will not affect future plans for bridge The City will be responsible for the maintenance replacement. and upkeep of a stand-alone bridge. Includes connecting path to Snelling Avenue. - I IMet�o-inet. us l ardenhills IPR�PWIParks IMemos I Council Memos 1011110 Municipal Agreement Update. doc
