Swale on Yale (Capitol Hill Water Quality Project)
SPU is working with Cascade neighborhood businesses and property owners to construct a stormwater treatment system on four blocks on Yale Avenue North and Pontius Avenue North.
Venema Natural Drainage System (Broadview)
Venema Creek is a tributary that flows into Piper’s Creek. This project is to construct a series of naturalistic “swales” to channel stormwater off the street and allow it to be absorbed into the soil.
