The Audubon Society of Portland


The Audubon Society of Portland voluntarily sought assistance from Lancaster Engineering to better understand the feasibility and costs associated with potential short- and long-term traffic calming solutions along their property frontage to improve pedestrian safety for people walking along and across NW Cornell Road. A range of options were explored and discussed in detail with staff from the City of Portland and Multnomah County.

Initial concepts considered for voluntary short-term implementation consist of: enhancing the safety and visibility of the existing marked crosswalk across NW Cornell Road with Rectangular Rapid Flash Beacons (RRFBs) and accompanying warning signage, reducing automobile travel speeds in advance of the marked crosswalk by re-striping/narrowing the travel lanes along NW Cornell Road, raising self-awareness of roadway users’ travel speeds by setting-up a speed reader board displaying the actual vehicle speed adjacent to the posted speed limit, and widening of the unsafe/sub-standard roadway shoulders along NW Cornell Road to provide both a safe space for walking and parking a vehicle. The Audubon Society of Portland is currently considering the approach they plan to take.
