Pottawattamie County engineers and staff briefed supervisors on traffic mitigation near the Google construction zone and said the company agreed to cover the cost of driver feedback (speed) signs and some speed‑limit signage.

Andy Wicks reported Google or its contractors agreed to pay for driver‑feedback signs and speed‑reduction signs. He said the speed limit on a segment of Pioneer Trail will be reduced from 40 to 35 mph and that feedback signs are to be installed on Wabash both northbound and southbound near Pioneer Trail to alert drivers.

Wicks said the signs should be installed "today" pending vendor availability, and staff will monitor until dirt hauling finishes at the site. Olson Engineering recommended signalizing the intersection of Pioneer and Wabash only if truck volumes reach roughly 200 trucks per hour; otherwise, staff may consider a three‑way stop. Wicks said stop signs could be installed within about a week but he preferred to run a traffic model first to evaluate queuing and safety impacts before making a permanent change.

Supervisors and residents also raised safety concerns after recent crashes were reported near construction traffic; county staff said they would coordinate with the sheriff's office to investigate crash causes. Staff plans to obtain updated traffic counts and consider an access‑management policy for future developments that would guide intersection improvements as new housing is built.
