Why Victory Heights Needs Bioswales

Victory Heights sits uphill from the Thornton Creek corridor. You might not think about the creek - you can't see it from here. But water doesn't care about neighborhood boundaries. Every drop that runs off your roof, your driveway, your lawn flows downhill into the system that ends at Matthews Beach.

The soil under Victory Heights is textbook alderwood - loose gravelly loam on top, impermeable hardpan underneath. The Vashon glacier compacted this layer 14,000 years ago, and it hasn't gotten any more permeable since. Water soaks through the first couple feet and hits a wall. Then it moves laterally, downhill, into the creek.

Upstream properties have outsized impact. A bioswale in Victory Heights reduces flow volume before it accumulates downstream. It's the difference between the creek handling a steady drip and getting slammed with a pulse of water every time it rains. The fix starts at the top of the hill.
