Hello,
There’s a region of SW Portland where streets visible on the basemap have no nodes in CS. I’ve narrowed down the cause and want to flag it before adding anything to the cities tracker, since it touches the import logic rather than being a single missing city.
The hole. Roughly bounded by Hwy 26/Sunset Hwy (north), SW Dosch Rd (east), SW Thomas St (south), and SW Scholls Ferry Rd (west). This area had nodes previously — I’d estimate they disappeared sometime in 2024.
Diagnosis. The hole sits in the “Portland IGA - West County” urban pocket per Multnomah County’s official map: https://multco.us/info/county-urban-pocket-areas. These are unincorporated chunks of Multnomah County that Portland administers under intergovernmental agreement. They have Portland 97221 addresses but sit outside the City of Portland incorporated boundary (relation 186579, admin_level=8) — which is what CityStrides currently uses for “Portland.” The tightening of that boundary may be why streets here lost their nodes.
The good news — admin_level=10 records exist for these neighborhoods. I checked Nominatim:
-
Bridlemile: relation 7748710, admin_level=10, boundary:administrative, polygon
-
Southwest Hills: relation 7739176, admin_level=10, boundary:administrative, polygon
Together these two cover most of the missing area. Both have linked_place=suburb and SWNI (Southwest Neighborhoods Inc.) website tags, suggesting the rest of the SWNI-affiliated neighborhoods (Hillsdale, Hayhurst, Multnomah, Maplewood, Healy Heights, Sylvan-Highlands, etc.) are likely tagged the same way. Some are entirely inside Portland and presumably unaffected; others probably have the same gap I’m seeing.
Ask. Would it make sense to import admin_level=10 neighborhoods in this Portland-area cluster as nested CityStrides cities under Portland? I’m aware of the overlap concern from the Calabasas/LA discussion — happy to help check which of these neighborhoods sit fully inside vs. straddle the city limit if that’s useful.
Thanks, Travis
