Mount Tabor Middle School Rain Gardens

Portland, Oregon

The Mount Tabor Middle School Rain Gardens projects are unique to Portland and the United States in the way this schoolyard campus has been transformed to sustainably manage stormwater runoff. The project was designed by Kevin Robert Perry in 2006 while he worked at the City of Portland, and it demonstrates City’s commitment to promote a more natural approach to stormwater management. What is particularly unique about this stormwater retrofit project is that it is first of several building, parking lot, and street stormwater retrofit projects specifically designed at the Mount Tabor Middle School campus to help solve a chronic neighborhood problem of local basement flooding. The first retrofit converts what was previously 4,000 square feet of underutilized asphalt parking area abutting the school’s courtyard entrance into an innovative rain garden designed to capture, slow, cleanse, and infiltrate nearly an acre of the school’s runoff. Prior to the rain garden’s installation, the students and staff described the parking lot courtyard space immediately adjacent to their classrooms as an “asphalt oven”. Even on the mildest of days, the heat generated from the asphalt parking lot would send the temperature within their classrooms soaring. After a careful site analysis, Kevin Robert Perry recognized several inefficiencies in the layout of the parking lot. By reorganizing the courtyard space, the design was able to provide sufficient room for a 2,000 square foot rain garden and an entry plaza with bike parking and student seating, while maintaining adequate parking for school staff. The project received a 2007 ASLA Professional Award of Honor in the General Design Category and is often toured by national and international visitors.
