Sustainability Principles
Sediment Clean Up Alternatives Analysis Lower Duwamish Waterway, Seattle, WA
Sediment Clean Up Alternatives Analysis Key Issues Legacy of industrial pollution in sediments Health risks Community concerns for neighborhoods Tribal fishing rights Degraded shorelines Degraded water quality Superfund site Heart of industrial corridor economic center of activity
Sediment Clean Up Alternatives Analysis Sustainable Design Elements Environmental Compliance Footprint Reduction (greenhouse gas, air emissions, waste) Economic Cost Reduction Maintain viable industrial activity Social Reuse and recycle Job creation Significant Stakeholder Engagement
Sediment Clean Up Alternatives Analysis Community Engagement Community Vision for restoration of the Duwamish River Coordination of community input through workshops
Habitat Restoration and Public Access Herring s House Park, Seattle, WA (JA Brennan)
Habitat Restoration and Public Access Key Issues Contaminated site from industrial uses Degradation of shoreline Loss of fish habitat Poor water quality No public access to Shoreline
Habitat Restoration and Public Access Sustainable Design Elements Environmental Maximize edge treatment Create variety of substrates Enhance fish and wildlife habitat Create better water quality Economic Costs for design comparable to alternative Social Aesthetic quality Improved access/recreation Sustainability/public awareness J.A. Brennan Associates
Seattle Seawall Replacement Seattle, WA (TetraTech)
Seawall Replacement Key Issues Critical structural deficiencies in Seawall Nearshore habitat degradation 60% overwater coverage decreases natural lighted areas Limited plant life and associated invertebrates under piers Significant economic activity
Seawall Replacement Sustainable Design Elements Environmental Increase light penetration Increase riparian vegetation Economic Textured Wall, Substrate Enhancement, Cobble Reefs Ensure ongoing economic viability of existing businesses Social Provide physical access to water Preserve social, cultural and historical uses of waterfront
Bulkhead Removal Seattle Olympic Sculpture Park, Seattle, WA (Weiss/Manfredi)
Bulkhead Removal Key Issues Seawall Required Replacement Contaminated Uplands Degraded Habitat for Juvenile Salmon Need to Accommodate Large Numbers of Visitors Lack of Shallow Water Habitat Lack of Sediment Supply Lack of Riparian Vegetation Significant Economic Activity
Bulkhead Removal Sustainable Design Elements Environmental Waterfront Brownfield Clean Up Restoration of Native Habitat/Vegetation Stormwater Management Nearshore and Salmon Habitat Economic Increase tourism activity Social Provide physical access to water Educational Programs and Partnerships Public Art Anchor Environmental
Green Stormwater Management Seattle, WA
Green Stormwater Key Issues Major contributor to pollution of Puget Sound Water quality pollution of urban waterways Likely contributes to the decline of salmon and bull trout, coho salmon and restrictions on shellfish harvesting in Puget Sound Increased cost for Combined Stormwater Overflow systems
Green Stormwater Sustainable Design Elements Environmental Use of engineered infrastructure Use soils and vegetation, in combination with other decentralized storage and infiltration approaches to infiltrate, evaporate, capture, and reuse stormwater (Low Impact Design) Economic Reduced cost for stormwater management Social Aesthetic improvement James Corner Field Operations
