Council packet considers new speed hump locations on Duff Street after resident safety concern

A Duff Street resident submitted input asking for a speed hump near the Acland Street intersection to slow northbound drivers who crest the rise and sometimes travel in the middle of the road, increasing head-on collision risk.

Streets & Utilities committee members reviewed engineering guidance: Strand and ODOT recommend using two speed humps on a long stretch and caution against humps on grades greater than 5 percent. The committee noted the Duff hill varies between 3–12% by location and proposed a temporary hump between 100 and 102 Duff, with a second possible hump south of the Morgan Apartments driveway if grade allows. Committee members also agreed existing speed-hump signage should be moved closer to the humps for clarity.

The packet records staff follow-up items: coordinate grade analysis with Strand/ODOT, finalize recommended locations, and return an ordinance or construction plan for Council approval.
