Inventory of SWTrails Signs

Brand New sign installed at West entrance to George Himes Park

SWTrails PDX is rolling out a new GIS-based tracking system to help monitor the signs guiding you through the 40-plus miles of urban trails in southwest Portland.   Using GIS technology, our volunteers will visit each of the 650+ signs in every corner of SW Portland to determine location, condition and other useful attributes – including pictures!

Our goal is to have a count of all signs on each jurisdiction so we can more effectively work with city, county, and regional partners to repair or replace signs as needed.

Our band of citizen-scientists began inspecting on April 18th to get an accurate count and picture of those ubiquitous brown signs.  Work will continue until complete.  Follow along as we catalog the signs by visiting our interactive dashboard here:


Present Condition: 

Many of our signs are cracked, faded, hidden by overgrown brush or trees, or covered in graffiti and stickers.  By getting an accurate count by location we can report, with only a few clicks, where these damaged signs are located and what we can resolve quickly with anti-graffiti kits and trimmers.

We are excited about the possibility of streamlining one of the many maintenance tasks we do for the benefit of our walking community.  To learn more, contact project manager Brian Brady at
