Session S-04H: Technical Tools to Support Sea Level Rise Adaptation in the Salish Sea

Description

Shoreline modification poses one of the most significant threats to the long-term health of shoreline ecosystems. Development pressures and sea level rise impacts are expected to increase demand for shoreline armoring across Puget Sound and the Salish Sea, limiting the effectiveness of recovery efforts for endangered salmon and orca whales. Current protection programs are not holding the line against ongoing incremental impacts to habitat and habitat forming processes. Resultant shorelines have a reduced resiliency to adapt to climate change impacts. Planning for sea level rise and cumulative effects are daunting management tasks that are frequently avoided as there is limited specific guidance available. A collaborative team of shoreline research and policy experts from local government, state and federal agencies, tribes and non-governmental organizations have developed new technical tools; analyzed existing regulations; surveyed planners, managers and decision makers and identified specific priority actions to improve effectiveness of current regulations and/or reform regulations. Project results including county scale inundation maps and erosion rate models; vulnerability assessment for property, infrastructure and structures; shoreline armoring habitat impact analysis; tidal elevation of surf smelt spawn study, a legal review of existing regulations and policies and associated management recommendations. Results are being applied to infrastructure, habitat and property protection planning in San Juan County Washington and disseminated across Puget Sound.

Planning for Sea Level Rise in San Juan County: Technical information and management strategies that support long-term protection of nearshore marine ecosystems
