Traffic study recommends signal and left‑turn lanes at 88th Street; county to require signal before occupancy
Summary
Kittleson Associates and Clark County staff said the 88th/94th intersection needs a traffic signal with left‑turn lanes and communications to the Patton Parkway signal; the county requires the signal to be operational before the public works campus or adjacent housing can be occupied.
Chris Braemer, the traffic engineer who prepared the study, told attendees his team evaluated existing and future conditions, counted trips and modeled several intersection options. After considering left‑turn lanes, all‑way stops, a roundabout and a signal, he said property constraints and monitoring wells made a roundabout infeasible. "Ultimately, the roundabout ran out of battery and using that logic signal alternative," Braemer said, and the recommendation is a signal with left‑turn lanes on each approach plus coordination with Patton Parkway.
County staff said the traffic signal at 88th must be installed and operational before the City or the adjacent housing project (Haslin/Aslan Acres) can proceed to occupancy. Braemer gave projected trip numbers for full build‑out—about 305 AM peak hour trips and 225 PM peak hour trips—and explained the project will pay traffic impact fees and fund local improvements as required. Clark County traffic staff also noted they retimed signals last fall to give more green time to southbound movements on 94th to partially address morning queues caused in part by school buses.
Why it matters: the signal will change access and may slow flows in some directions, but county staff said communication between signals and developer‑funded intersection work is required before new development can be occupied.
