Engineer recommends stop control at M & 11 intersection after sight‑line study
Summary
An Oak Creek Engineering study found substandard sight distances at the Road M and Road 11 T-intersection and recommended stop or yield control on minor legs; commissioners directed staff to draft a resolution for traffic control and return with bids or documentation.
Brent Carter of Oak Creek Engineering presented a traffic-safety study for the Road M and Road 11 intersection, telling commissioners that sight-distance triangles on the minor approaches were below guideline levels and that the location had a history of multi-vehicle crashes (no injuries reported).
Carter said one approach had only about 355 feet of sight distance, which he described as "substandard for the prevailing speeds," and that vertical profile issues on the east side of the intersection also reduced visibility. Based on those findings, the consultant recommended installing control on the minor legs (yield or stop signs) and, in some cases, considering an all-way stop depending on final sight-line mitigation.
Commissioners discussed possible mitigations — including trimming or removing private trees near right-of-way, classifying similar intersections countywide, and using county-wide standards rather than ad hoc solutions. The board directed staff to draft a resolution authorizing the recommended control and to bring it back at the next meeting with the technical justification and recommended sign placements.
Residents near the intersection were reported to be generally supportive of adding controls. The board agreed a formal resolution and backing documentation (engineer recommendation) would be required to implement new signs.
