Summary

City staff told the Traffic Advisory Commission that a corroded corrugated culvert north on Elm Road requires excavation and replacement with a larger cast‑in‑place culvert; the construction contract is five months and Elm Road (Lockwood to Brentwood) will be closed with detours planned.

City staff told the Traffic Advisory Commission that a corroded corrugated metal culvert on the northmost section of Elm Road must be removed and replaced with a larger cast‑in‑place culvert, requiring excavation that will produce a hard closure at the work site.

Speaker 7 explained the recommended work and said the construction contract duration is five months once work begins; the team described staging with soft barricades early in the block and a hard closure at the excavated area where the culvert will be replaced. Commissioners asked about detour routes; Speaker 7 said northbound traffic would be routed via Big Bend and Manchester with signed detours and that some intersections and narrow streets will be constrained for truck access.

Speaker 5 confirmed the lane closure would apply to Elm Road from Lockwood to Brentwood during the construction period and that staff will install detour signs encouraging major thoroughfares rather than local residential cut‑throughs. Commissioners raised speed‑limit consistency and side‑street capacity as concerns; staff agreed to provide more detailed detour and signage plans as they finalize schedules and permitting.

The commission did not take a formal vote but asked staff to proceed with design and scheduling, and to provide public notice about timing and detour routing prior to construction.
