South Portland Addressing Project

Wayfinding, 9-1-1 Dispatching & Emergency Response Improvements

Sixth SextantThe Portland Bureau of Transportation has been collaborating with Portland Fire & Rescue, the Portland Police Bureau and Multnomah County to improve wayfinding, 9-1-1 dispatching and emergency response in the area of Southwest Portland east of SW Naito Parkway. Due to the eastward curvature in the Willamette River, east-west addresses in this area are currently addressed with a leading zero address to differentiate them from addresses west of this dividing line. About 8% of Southwest Portland addresses are in this leading zero addressing area.  This area will be readdressed as South Portland in May 2020 per Council approval on June 6, 2018.

Portland Fire & Rescue (PF&R) staff and Portland Bureau of Transportation (PBOT) staff were directed to implement a solution to eliminate this issue, including for unincorporated Multnomah County areas served by the City. Wayfinding, 9-1-1 dispatching and emergency response issues increase each year as development and population growth occurs in the leading zero addressing area, especially in South Waterfront. 

In addition, the spelling of SW Radcliff/Radcliffe Street and SW Radcliff/Radcliffe Lane in Crestwood N.A. outside the leading zero addressing area will be standardized. Similarly SE Martin Court in Woodstock will be renamed to SE Martins Court consistent with nearby SE Martins Street. The current spelling on property owners’ addresses, street signs and the official names of these streets sometimes differ. The spelling of all other Portland street names are standardized elsewhere throughout the City.
