How do you start to Adapt? If you had maps and information identifying vulnerable assets, what would you do with it?

Focus Area 1: Wickford Village
Mapping Marsh Migration Sea Level Affecting Marshes Model (SLAMM) Simulates the dominant processes involved in
wetland conversions and shoreline modification during long-term sea level rise Applied and improved since 1985 Used throughout the country
http://www.warrenpinnacle.com/prof/SLAMM/
The SLAMM Model Model Process Specify time period and projected rate of SLR Inundation Calculated based on slope and elevation
Erosion Based on fetch and proximity to open ocean Overwash Beach migration and sediment transport based on storm interval
Saturation Movement of fresh and coastal wetlands in response to rising water table Accretion Vertical rise of marsh due to buildup of organic and inorganic matter On the ground rate can vary from site to site and through time
What can we do??? Develop alternatives for “hard” shoreline protection structures
Protect undeveloped areas for future salt marsh
Enhance coastal buffers; increase setbacks
Next Steps Statewide
Confirm/refine SLR assessment methodology and map
products Assess vulnerability of transportation (roads, bridges, rails, evacuation, etc) and other sectors (i.e. wastewater) Assess implications to coastal wetlands to SLR and impediments (i.e., shoreline structures) Develop strategies (policy, outreach, action) in communities and state Utilize LiDAR for other analysis, such as increased flooding in riverine areas Enhance Science, Partnerships, Leadership, and Resources
Next Steps Statewide Revise state SLR policy to include standards for building
and buffer zones Analysis of information for state Climate Commission Evaluation of state road infrastructure Education of state policy/general assembly/community leaders and planners Identify other communities who are interested Implement actions (living shorelines, buffers, zoning/building WWW access – Sea Grant and Waves of Change
Next Steps Local Applications Open space acquisitions – ID and prioritize lands for
protection, salt marsh creation Regulatory impacts – zoning ordinance and comprehensive plan amendments Hazard Mitigation Plan – incorporate and implement actions Comprehensive Plan- incorporate strategies for adaptation for future land use decisions Educate Locally - distribute information to elected officials, homeowners, and business owners
Next Steps Local Applications Incorporate into town GIS and IMS - more accessible
information CRS impacts – achieve lower rating Transportation – ID roads and infrastructure inundated CIP – Plan for future spending TIP – incorporate into future application Building Code - work with RIBA and CRMC to modify code in coastal zone
