Carroll council approves design contract for US 30 signal upgrades; ADA and pedestrian costs remain unresolved
Summary
Council approved a $253,300 professional-services agreement with Snyder & Associates to design improvements at 11 US 30 signal locations, including required topographic survey and federal clear‑zone-driven pole relocations; council asked staff for more precise cost estimates for optional pedestrian signals.

The Carroll City Council approved a professional-services agreement with Snyder & Associates for design of US 30 traffic-signal improvements, authorizing $253,300 in project design fees and asking staff to return with refined cost estimates for pedestrian crossings.
Staff said the fee covers engineering services to develop the project through bidding for work at 11 signalized intersections along Highway 30, including anything from minor upgrades to full signal replacements. A topographic survey component of the work was noted at $44,000. City engineering staff said updated federal clear-zone standards and ADA requirements will likely require some pole relocations and intersection reconstruction.
Council members pressed staff on the scope and cost: one councilor asked whether a topographic survey was necessary if the signals were unchanged since the 1970s; staff replied that federal safety and ADA changes require fresh surveys and that even small offsets can affect pole placement and ADA ramp grades. Staff said a full pedestrian signal (with a red indication requiring vehicles to stop) would require upgraded controllers and construction comparable to a vehicle signal and estimated the cost to add such pedestrian crossings at selected locations could be on the order of several hundred thousand dollars (discussion referenced a ballpark figure near $350,000 for an additional signal installation).
Randy (public works/staff) summarized the schedule: staff anticipates initiating the project immediately, bidding in January 2027, and completing construction in calendar 2027; he said most traffic disruptions would occur during structural work and would be managed with traffic control plans. Council approved the professional-services agreement and directed staff to obtain more-specific pedestrian-signal cost estimates before committing to those optional installations.
Votes and follow-up: the motion to approve Snyder & Associates’ agreement carried on roll call. Staff will return with more-detailed cost estimates for pedestrian signals and the consultant’s refined scope for council review prior to bidding.
Representative quotes from the meeting included staff explanation that the federal government now requires a clear zone between traffic and poles, and a councilor’s observation that “a half inch makes a difference” for ADA conformance when reconstructing curb ramps and intersections.
