Comments:
Buckman Heights was one of the first buildings in the Portland-Vancouver area to integrate a variety of water quality friendly features into the building’s design. One of the award winning building's features is a vegetated infiltration basin that also functions as the building’s main courtyard.

Comments:
These vegetated infiltration basins at ShoreBank Pacific absorb a majority of the building’s stormwater runoff. They are planted with native plants designed to withstand the coastal environment. Vegetated infiltration basins at both the front and back of the building ensure little to no stormwater leaves the site.

Comments:
Stormwater runoff from the Wattles Boys and Girls Club is directed to these two large infiltration basins that have been seamlessly incorporated into the building’s landscaping. Small culverts carry stormwater runoff from one basin to another lengthening the infiltration period.

Comments:
This teacher and student led project incorporates disconnected downspouts, two large cisterns, a small pond, and a vegetated infiltration basin. Stormwater runoff from the school’s portable buildings eventually makes its way to a student planted infiltration basin where it is absorbed by plants and infiltrated into the soil. This picture shows the newly planted basin.

Comments:
Previously the parking lot at Grant High drained to a typical storm drain. A portion of the parking area was disconnected from the stormwater system by punching some drainage pathways in a retaining wall and constructing an infiltration basin. Infiltration basins are generally designed to hold up to 12-18 inches of water and drain within a few hours of a storm event.
