Stormwater Retrofit at Mt.
Tabor Middle School
5800 SE Ash Street, Portland, Oregon
Project Summary
Project Type A school retrofit to protect nearby residents from surcharging of the combined sewer
Technologies A variety of vegetated infiltration facilities and drywells
Benefits The facilities capture runoff from about two acres of roof, parking lot, play area, and street.
They infiltrate most of the captured flow, helping reduce combined sewer overflows (CSOs).
They are attractive additions to the school grounds, help shade and cool the south side of
the building, and provide an educational resource for students.
Notable
Features
The project showcases a range of applications for vegetated facilities that create a greener,
healthier environment for the students and staff at the school.
The rain garden received a 2007 Design Award from the American Society of Landscape
Architects (ASLA).
Cost The fully loaded cost of construction was $523,000.
