Some Pinehurst properties back up directly to Thornton Creek. Zero buffer between your yard and the waterway. What runs off your property hits the creek in minutes.
Apply for Pilot ProgramPinehurst is where Thornton Creek is most visible - and most vulnerable. Properties here border the riparian zone directly. There's no park buffer, no commercial strip, no distance between your back fence and the waterway. What leaves your property enters the creek system almost immediately.
That proximity cuts both ways. During heavy rain, creek levels rise and the water table comes up with them. Basements flood. Yards saturate. The hardpan underneath - the same compacted glacial till the Vashon glacier left across all of North Seattle - traps water between the surface and the impermeable layer below.
A bioswale in Pinehurst isn't just about managing your own runoff. It's the last line of defense before the creek. Engineered bioretention captures pollutants, slows flow velocity, and reduces the volume of water hitting the creek during peak storms. For creek-adjacent properties, that's not a luxury - it's infrastructure.
