The densest neighborhood in the watershed. More rooftops, more pavement, more runoff per square foot than anywhere else. Even a small bioswale matters here.
Apply for Pilot ProgramThe University District packs more impervious surface into a smaller area than any other part of the Ravenna Creek watershed. The UW campus, apartment buildings, commercial strips, and parking lots create enormous volumes of stormwater runoff that the aging infrastructure struggles to handle.
For the residential properties that remain - the houses on quieter streets away from the Ave - every square foot of permeable ground matters. You're surrounded by density. Your yard is one of the few places where water can actually soak in rather than run off into the storm drain.
The soil underneath is the same glacier-deposited alderwood as everywhere else - topsoil over hardpan. But in the U-District, the ratio of impervious to permeable surface is so skewed that even a small bioswale has outsized impact. One residential bioswale in a sea of pavement captures and filters water that would otherwise add to the combined flow overwhelming the system downstream.
Tailored stormwater and landscaping solutions for your property.
Bioswale design for U-District properties of all sizes. From compact rain gardens to full bioretention systems, engineered for dense urban lots.
Stormwater management for the U-District's high-runoff properties. Every gallon captured here reduces pressure on the Ravenna Creek system downstream.
Professional landscaping that maximizes green space on urban lots. Native plants, low maintenance, and curb appeal for the U-District market.
We're selecting 5 founding homeowners for our first residential bioswale installations. In the U-District, every permeable square foot counts - your property is an opportunity the neighborhood needs.
