In the 1990's and early 2000's, residents of the Mount Tabor neighborhood along SE 53rd Avenue were experiencing frequent sewage flooding in their basements. Environmental Services studied the problems with the sewer system in that area and found that the pipes, built in 1937, were not large enough. Too much stormwater was running off area streets and parking lots and into the pipes, causing sewage to backup in the basements of homes along the block.

There were two solutions to the problem - replace and enlarge the pipes in the area, or construct facilities on the surface to slow and retain the runoff so it doesn't reach the sewer pipes. After extensive analysis, the City partnered with Portland Public Schools and Glencoe Elementary School to design an innovative bioswale and rain garden that captures runoff, slows it down, and keeps it from entering the sewer and contributing to back up.. (See the project fact sheet here). The project was completed in 2003.

Now, 10 years later, the facility continues to do its job! Here’s what we know:
In addition to providing residents and students with access to a pleasant, park-like setting, the rain garden serves as an extension of the school's outdoor classroom and butterfly garden.
