Puyallup Green Street [10]

Puyallup has its first Green Street—though for now it’s still called 8th Avenue.

The 8th Avenue Low-Impact Development (LID) retrofit encompasses more than 18,000 square feet of porous asphalt roadway, 3,200 square feet of permeable sidewalks, and 11 rain gardens. Thanks to these improvements, 100 percent of the block’s polluted stormwater runoff infiltrates soils and avoids entering storm drains—that’s an estimated 890,000 gallons of stormwater annually.

Choosing a green approach saved the city about $100,000, compared to a traditional construction that lacks a mechanism to purify water, and is built using regular asphalt, storm piping, and old-style catchment structures. Traditional methods would have sent the polluted water to Clarks Creek, from there to the Puyallup River, and eventually into Puget Sound.

The Green Street structures have proven to be both financially savvy and effective.  Not only is Clarks Creek water quality protected (Clarks Creek is home to five species of salmon), but 8th Avenue requires significantly less maintenance now that flooding events have been eliminated. In addition, the community benefits from a more beautiful neighborhood resulting in traffic calming and increased property values.
