In 2007, the City of Seattle added to the restored area in the southwest corner of Turning Basin Number Three, successfully removing approximately 0.4 acres of previously placed fill and stabilizing approximately 400 linear feet of bank line with large woody debris and riparian plantings, complemented by removal of invasive plants in approximately 2.1 acres adjacent to the shoreline site, and replanting the cleared area with native vegetation to establish an upland buffer area.
