Pervious concrete pavement was used to solve water retention, stormwater runoff and slope stability problems for a 16-acre housing development at Picnic Point in Snohomish County.

The key to making the land developable was connecting its upper 10 acres with its lower 6 acres with an 800-foot driveway. Using pervious concrete paving allows the driveway to absorb stormwater and replenish ground water supplies while protecting salmon habitat in Puget Sound.

The driveway’s subgrade is 18 inches of sand under 6 inches of washed gravel. The pervious pavement on top is 6 inches thick. After two sample pours were tested, crews spent three days pouring a total of 248 cubic yards of the material.
