Public Works Memorandum NO. 2012-33 DATE: April 9, 2012 TO: Honorable Mayor McElroy and City Council FROM: Ryan P. McCrady, City Manager Richard G. Marley, P.E., Public Works Director SUBJECT: Authorization of Motor Fuel Tax Funds to Purchase Right of Way and Temporary Construction Easements for the Replacement of the South Shores Bridge over the Sand Creek Arm of Lake Decatur City Project 2009-05, Section 09-00905-00-BR SUMMARY RECOMMENDATION: It is recommended that the City Council approve the attached Resolution authorizing the Mayor to sign and the City Clerk to attest to the appropriation of$41,000 in Motor Fuel Tax (MFT) funds to purchase right of way and temporary easements required for the South Shores Bridge project. PRIOR COUNCIL ACTION: Appendix A provides a summary of prior Council actions related to the South Shores Bridge construction. BACKGROUND: South Shores Bridge Replacement The South Shores-Sand Creek Bridge was originally built in 1909. A new superstructure was placed on the old abutments in 1965. The foundation and abutments are 100 years old and the super-structure is 45 years old. Routine inspections carried out by City staff and various consulting engineers since 2004 have determined that the outside beams of this bridge are deteriorating and have moved with respect to the rest of the bridge. In August 2006,the Illinois Department of Transportation (IDOT) directed the City to place a weight restriction on the bridge and to perform follow-up inspections every 6 months to monitor the outside beams of the bridge. Since the damaged beams are not in the wheel path, the bridge is safe for normal traffic; however, the 6 month inspections show that the bridge's deterioration is increasing. The bridge needs to be replaced in the near term before stricter traffic restrictions are imposed. Public input gathered as part of the design process indicated a desire to raise clearance height of the replacement bridge. The City Council supported the proposal to raise the bridge by 3 feet. $1.04 million in Federal Surface Transportation Program—Urban (STU) funding is proposed to fund a portion of the bridge replacement cost. Current estimates show the bridge and roadway replacement cost at $2.65 million and the cost to raise the Sanitary District interceptor at $500,000. Page I 1
