SEPA Determination of Non-Significance (DNS) of Proposed Action

The Port of Seattle has completed an environmental analysis, including review of pertinent and available environmental information and preparation of an Environmental Checklist for the following proposal:

Description of the Proposed Action: The proposed shoreline rehabilitation project includes re-grading port-owned Duwamish Waterway margin and adjacent City-owned South Riverside Drive right-of-way to restore inter-tidal and shoreline conditions and improve publicly accessible shoreline.

The proposed project includes approximately 180 linear feet of port-owned shoreline and upland on the west margin of Duwamish Waterway and the water-ward portion of South Riverside Drive, City of Seattle right-of-way, adjacent to port shoreline ownership. The existing abrupt and eroding filled shoreline area includes industrial rubble, debris, and a derelict wooden barge. Existing upland area includes unimproved Port shoreline property and City right-of-way formerly used for vehicle parking and uncovered construction materials storage.

The proposed shoreline rehabilitation project includes two elements: (1) inter-tidal area clean-up, including removal of an existing derelict wooden barge and removal of industrial debris and rubble and (2) re-grading an existing eroding, rubble filled bank line, removing previously placed fill material to rehabilitate inter-tidal area, followed by installation of large woody debris, native marsh, riparian, and upland vegetation.

Location of Proposed Action: The proposed shoreline rehabilitation site, including combined Port of Seattle, Duwamish Waterway property and South Riverside Drive, City of Seattle, right-of-way area, has no street address. The project site is located on the west shoreline of the Duwamish Waterway, near River Mile 3.2, approximately 450 linear feet east of the South Riverside Drive/South Holden Street/Seventh Avenue South intersection and approximately 170 feet north of the South Portland Street/Eight Avenue South intersection.
