Green Streets Program
In November 2010, Clark County finished its first “Green Street” project by planting thousands of trees, shrubs and grasses along a 20-block section of NE 99th Street, immediately east of NE 117th Avenue/SR 503.
The NE 99th Street project relies on rain gardens to clean stormwater before it slowly soaks into the ground. Using plants is a natural way to treat stormwater pollution, which the Washington Department of Ecology has identified as the state’s No. 1 threat to urban water quality.
Public Works also used rain gardens at Luke Jensen Sports Park, 4000 NE 78th St., and build a series of rain gardens to improve water quality in the Mount Vista area north of Washington State University Vancouver.
Pervious paving is another environmentally friendly construction technique that eliminates the need for stormwater ponds or other facilities that collect and treat runoff. Pervious pavement was used on sidewalks as part of the NE 99th Street project,
Public Works also used pervious paving along most of the NE 159th Street walkway between Hockinson Middle School and Hockinson High School. In addition, pervious pavement was used for most of the Salmon Creek Park & Ride lot that was built as part of the Salmon Creek Interchange Project.
Public Works is committed to using environmentally friendly construction where it is technically feasible and financially prudent.
