Resident urges county to review rumble‑strip placement after noise complaint; staff agrees to inspect

At the public comment period a resident introduced by the clerk as "Mister Trampon" (S8) asked the board to investigate rumble strips recut near his home that he says are audible inside the house and located closer than Iowa DOT guidance recommends. "I was honestly shocked by the amount of noise they created, not only outside my house, but also inside my residence," S8 said, and provided video evidence.

County staff and engineers (S9, S7) described the installation and inspection process. S9 said crews found one pass that had been cut deeper than the standard 3/8 inch because the machine made two passes and that the county filled the first, deeper cut to bring it closer to spec. He cited Osceola County Ordinance 48, which mandates rumble strips at intersections in the county, as the local requirement that informs the practice.

Board members pressed staff on options. Staff discussed several possible responses: remeasuring and recutting to meet the published standard, relocating the "stop ahead" sign (which would change rumble‑strip placement), or adding flashing beacons as an alternate advanced warning device. Staff also noted state procurement and material specifications could limit what can be done on state highways and that beacons may be less visible in heavy fog.

The board agreed to have engineering staff review the measurements and the standards and to follow up with the resident. No immediate policy change was adopted at the meeting; staff committed to further inspection and a report back to the board.

What to watch: staff said they will review the stop‑ahead sign placement and the rumble‑strip depth/placement and return with options, including whether a flashing beacon or recut would be appropriate.
