Thornton Creek

Creek in North Seattle that empties into Lake Washington

Thornton Creek is 18 miles (29 km) of urban creeks and tributaries from southeast Shoreline through northeast Seattle to Lake Washington. Its 12-square-mile (31 km2) watershed, the largest in Seattle, exhibits relatively dense biodiversity for an urban setting;[4] it is home to frogs, newts, ducks, herons, and beavers, in addition to more than 75,000 people.[5] From west of Jackson Park Golf Course in Shoreline,[6] from Sunny Walter-Pillings Pond[7] in Licton Springs–North College Park,[8] and north Northgate[9] Thornton Creek flows through Maple Leaf and Lake City, including the Victory Heights, Meadowbrook, and Matthews Beach neighborhoods, and empties into the lake at Matthews Beach Park.

Habitat and stewardship

Thornton Creek flows through Meadowbrook Pond,[10] known for its birdwatching and resident beavers. The Thornton creek watershed is land formerly inhabited by the Duwamish tribe. One of the Duwamish's historic longhouse sites was located near the mouth of Thornton Creek at Mathews beach.[11] Early in the 1900s, the creek contained dense runs of at least five species of Pacific salmon and trout, today only a few Kokanee still travel up stream.[4] The areas surrounding the creek were developed without regard for that habitat and the riparian corridor; species' diversity declined, and the creek became a typical degraded urban watershed.[12] Storm water retention, sites restoration, an Environmental Learning Center next to a school, and a fish ladder contributed to restoration and the return of native plants and wildlife.[13] Thornton creek is home to many native species, muskrats, beavers, otters, bats, crayfish and coyotes, and in addition is an important breeding ground for great blue herons. Common for urban creeks, there are also many problematic invasive species like Japanese knotweed, black rats and New Zealand mud snails.

Thornton Creek Water Quality Channel

For many decades, much of the stream has run through culverts, notably under the parking lot of Northgate Mall. Building on gradual successes in restoration,[7][14] activist neighbors began[6][15] working with the City of Seattle and developers toward daylighting parts of the buried creek.[16]

In 2004, the City of Seattle purchased the 2.4-acre (0.97 ha) parking lot from Northgate Mall and began building the Thornton Creek Water Quality Channel. Opened in 2009, it achieved several community goals in limited space: integrating a water-quality facility, providing a diverse housing mix, and allowing public open space. It receives and treats runoff from 680 acres (280 ha) by providing a multilayered landscape of native plants that also serves as an amenity for surrounding private development.[17]

Organizations of citizens have cleaned up nearby wetlands, educated the public about stream health and quality of neighborhood life, and rallied to bring more of the creek to daylight. Many restoration projects in Seattle have been in some way connected to or inspired by Thornton Creek.[18]
