Title: Habitat Restoration in the Commencement Bay Nearshore


1
Habitat Restoration in the Commencement Bay
Nearshore Tidelands Area
2
Citizens for a Healthy Bay (CHB)
  • Founded in 1990 to provide community oversight
    into the superfund remedial action.
  • Over 900 members representing the commencement
    bay community and south Puget sound.
  • Works cooperatively with all stakeholders
  • Communities, neighborhoods and other public
    stakeholders.
  • Potentially responsible parties.
  • Economic development and other business
    interests.
  • Local, regional, state and federal agencies.

6
Historical Landscape Structure
  • Extensive tidal freshwater floodplain of a
    meandering Puyallup river accompanied by
    extensive off-channel sloughs and wetlands.
  • Prograding delta with numerous distributary
    braided channels.
  • Well- developed system of dendritic channels in
    an emergent marsh zone.

7
Historical Landscape Structure
  • Extensive estuarine transition zone between
    upland habitats and emergent marsh zones.
  • Broad, expansive mudflat habitat.
  • Extensive system of cross-delta migration
    corridors.
  • Regular inputs of wood, cobble and sand from
    adjacent hillslopes.

8
Current Landscape Structure
  • Less that 1 of historical estuarine habitat -
    disconnected and isolated
  • No cross delta migration
  • Puyallup river channeled
  • Steep armored banks

9
Commencement Bay Habitat Restoration Efforts
  • Superfund
  • Natural resource damage assessment (NRDA)
  • Endangered species act (ESA)
  • Landscape scale restoration vision
  • Watershed restoration

10
Superfund
  • 4 Tacoma domes of contaminated sediment
  • Metals, PCBs, dioxins, PAHs, organics
  • Nearshore and tidelands a biological desert
  • Commitment to combine cleanup with habit
    restoration

11
Natural Resource Damage Assessment
  • Goal is to restore coastal and ocean resources
    that have been injured by releases of oil or
    hazardous substances and to obtain compensation
    for the public for their losses.

12
Watershed Restoration
  • Recovery efforts must also address Commencement
    Bay as the saltwater estuary of the Puyallup
    River.
  • Mixing zone between salt and fresh waters
  • Exceptionally high productivity
  • Estuarine 800 3500 grams/m2/year
  • Tropical forest 1000 3500 grams/m2/year
  • Area where most plankton production takes place
  • Cornerstone of healthy marine ecosystem

13
1999 - Endangered Species Act (ESA)
  • Puget sound Chinook and bull trout
  • Superfund vs. ESA
  • Engaged more entities city, county, region,

14
Commencement Bay Restoration Vision
  • Emphasis on baywide restoration through an
    ecosystem or landscape approach rather than
    creating isolated fragments of habitats
  • Mudflat and salt marsh restoration
  • Foundation for the future

15
Commencement Bay Restoration Sites
16
YOWKWALA
  • Enhance intertidal area for juvenile salmonid
    migration.
  • Maintain marsh vegetation.
  • Protect the site for natural resources.

17
SKOOKUM WULGE BEACH
  • Design and construct intertidal habitat
    enhancements,
  • Capture high quality, year-round freshwater
    runoff from uplands and incorporate it into an
    intertidal marsh,
  • Restore subtidal areas to productive benthic
    habitats where impacted by wood debris from log
    storage operations,

18
Squally Beach
  • Establish backwater ponds
  • Create interstices for invertebrates and juvenile
    salmonids
  • Establish areas for salt marsh vegetation
  • Protect the site for natural resources

19
Sqaully Beach
20
Mowich
  • Enhance fish habitat for juvenile salmonids
  • Establish backwater pools
  • Establish areas for salt marsh vegetation
  • Protect the site for natural resources

21
Middle Waterway
  • Enhance intertidal area for juvenile salmonid
    migration.
  • Establish marsh vegetation.
  • Possible fresh water connection channel to/from
    Puyallup River

22
Upcoming Projects
  • Hylebos marsh
  • Olympic view
  • Sha-dax
  • St. Paul
  • Swan Creek
  • Tahoma salt marsh

23
Overview
  • Baywide restoration
  • Ecosystem/landscape approach
  • Provide corridors and connections
  • Salt marsh and off channel habitats
  • A work in progress for the future

24
What Can You Do?
  • CHB provides many hands-on opportunities to get
    involved in habitat restoration
  • Planting
  • Site maintenance
  • Site stewardship
  • Site monitoring
