M-9 - City Engineer Report

City of Tiffin August 29, 2024 PROJECT UPDATE Highway 6 Concept and Cost Estimate – James Watters Field exam meeting was held virtually on 6/26/24 with City and IaDOT staff. Meeting minutes from the meeting can be provided upon request. DOT has requested the City consider sidewalk between Stephans St and Kimberlite St on the north side of USH6/Marengo Rd. Originally, there was a planned gap in sidewalk connectivity due to steep backslopes and the potential need for retaining walls. The IaDOT has concerns for pedestrian safety. See below comment from IaDOT Construction Specialist Danielle Alvarez MSA has submitted utility information request letters to private utilities located within the corridor on 7/23/24 “I think we should reconsider providing continuous sidewalk on the north side of HWY 6 ( area shown on Sheet D.3). I know the block between Stephans Steet and Croell has quite a backslope which could be challenging/require a wall. However, those two intersections already have operational problems with common fender bender type issues with left turners accessing Fareway, Casey’s etc and we’ll be introducing another variable with pedestrian crossings as part of this project. There’s a memorial cross in the SW quad of Stephans and I’ve seen quite a few near misses, etc at Croell. Perhaps pedestrian signals at select location(s) might be an option?” Does the City want MSA to explore this option? We believe that the additional cost of the retaining walls, sidewalk, and storm sewer would all be City costs. We have not done cost estimates because we don't want to put in that extra effort if it's not something the City wants to entertain.
