My “In the ‘hood…” Series:
The Built Green Community of High Point in West Seattle has an approx 2.5 acre pond, with a 1/4 mile walking trail around it. High Point totals 120 acres, which makes up 10% of the Longfellow Creek watershed downhill in Delridge. All of the runoff from homes and streets and parks goes into bioswales placed throughout the community. Plants then filtrate the water for a time before the water makes it into a permeated culvert, that then directs the water to the pond. The pond holds water here so during heavy rains there is less flooding in the valley below.
If you missed the video when the pond was first drained (labeled Part 1), you can watch it here:
