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.

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.

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.

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

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

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.

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

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
