Tanner Springs Park is a city park in the area of downtown Portland, Oregon known as the Pearl District.HistoryPart of a 1999 Pearl District plan, the park was originally named North Park Square, but was renamed in April 2005.Originally, the park was to be designed by Maya Lin, but concerns about her large sculpture, called "Playground", worried Pearl District residents who did not want another child-friendly park only two blocks from Jamison Square.DesignConnected to the busy Jamison Square two blocks away by a wooden boardwalk made of ipê, Tanner Springs Park is quiet and naturalistic, designed by Atelier Dreiseitl and GreenWorks PC. Stripping away the industrial cover helped reconnect the neighborhood with the pre-industrial wetlands, especially Tanner Creek, which ran through the area. The New York Times described it as "a sort of cross between an Italian piazza and a weedy urban wetland with lots of benches perched beside gently running streams." The waterscape was designed by architect Herbert Dreiseitl, who spent time perfecting the sound made by the rushing water. The park is planted with tall native grasses, and includes Oregon oak, red alder and bigleaf maple trees, salvaged in the region and planted as mature trees.
