Bear, Mary's, and Ferris Creeks Habitat Restoration Project

The Columbia River Estuary Study Taskforce (CREST) is soliciting bids for the construction of the Bear, Mary’s, and Ferris Creeks Habitat Restoration Project. The three creeks within the project footprint are tributaries to the Lower Columbia River Estuary and are located near Svensen Island, approximately 11 miles east of Astoria along Highway 30 in Clatsop County, Oregon. This project is sponsored by the Bonneville Power Administration and CREST. Site ownership consists of three private property owners, Clatsop County, ODOT rail, and Portland & Western Railroad (PNWR). CREST requires a contractor with task specific knowledge and expertise.

CREST proposes to implement restoration and enhancement actions at the Bear, Mary’s, and Ferris Creeks site in order to maximize the habitat potential for juvenile salmon, Columbian White-Tailed Deer, and other stream and riparian dependent species. The project concept consists of strategically breaching and removing sections of existing remnant levee along Bear, Mary’s, and Ferris Creeks. Additionally, other restoration opportunities such as channel excavation, ditch fill, and on-site cast/shaping of spoils to create topographic habitat features. Restoration designs are intended to restore fish access, be beneficial to native vegetation and the Columbian White-Tailed Deer, and restore natural hydraulic flows and nutrient cycling within the Bear, Mary’s, and Ferris Creek systems. Work includes installation of erosion control measures, levee and channel excavation, removal of several failed/derelict culverts, placement of large woody debris, placement and grading of excavated materials, and replanting and seeding (see attached specification document). Site Access will be based around the tides, as the levee system has failed and the site is currently tidal. There will be no unnecessary tracking of equipment outside of the project footprint.

Specific project objectives include:

  1. Restore natural hydraulic flows and tidal process (hydrologic connectivity for fish access) by removing failed infrastructure (tidegates/culverts/levees) along Bear Creek, Mary’s Creek, and Ferris Creek floodplain properties
  2. Improve habitat capacity and complexity for juvenile salmonids by filling old ditch networks and excavating new marsh channels to create longer more natural flow paths
  3. Increase prey resource production and availability for juvenile salmon by creating topographic complexity mounds which promote a diverse native plant community capable of supporting a productive foodweb
  4. Enhance and manage vegetation – consistent with re-introduced hydrologic regimes to compete against future infestation by invasive plant communities, and restore long-term processes of large wood recruitment
  5. Minimize impacts to wetlands, aquatic habitat, and adjacent properties

Project proposals are due May 21, 2018 by 4pm. A mandatory site visit will take place on Tuesday May 8th. You must RSVP for this site visit before the end of business Monday May 7th.
