Information and tools to support place-based decision-making

Bringing the message home to the local level!

Workshop Survey Results: The audience of coastal decision makers highlighted their perceived need for place-based information and decision support tools to inform land use planning, floodplain management and emergency management in the face of accelerating sea level rise.

Designing decision support tools related to SLR:

• Tools should incorporate information

ascertained through scientific research and modeling that can be easily applied by governments and landowners when planning future land use and deciding on policy and regulations that affect coastal resources;

• Tools should forecast expected habitat changes, especially potential loss of habitats important for ecological services;

• Tools should be easy to translate to decision makers;

• Tools should enable easy understanding of potential risks to people and development due to future flooding and related hazards.

(NOAA Center for Sponsored Coastal Ocean Research, 2007)

NJFloodMapper • Goals: to broaden access to vital geospatial

information with the goal of empowering a wide and diverse community of concerned parties interested in coastal management and conservation.

• Research Objectives: to examine how web-based geospatial decision-making tools can be developed and implemented to promote coastal resilience in the face of sea level rise and extreme storm events:

• Outcomes: Develop a focused web-based mapping application with an intuitive interface and gentle learning curve.

So Many Tools: which to use?

Closing Thoughts: • WebGIS tools, such as NJFloodMapper, can provide

access to critical place-based information on coastal flood exposure and potential vulnerability.

• Leveraging national-scale effort with locally-refined

geospatial data and functionality is a good model. – Providing a local scale – municipal focus – Adding local data and functionality requested by the community

Closing Thoughts:

• The user-centered design process was central to that elusive goal of “virtual accessibility.” – Fostered connection to target audience. – Promoted greater acceptance once tool was

released. • Proliferation of WEBGIS SLR tools can be confusing

to the end-user community. • Even with great WEBGIS tools, community level

planning still needs a personal touch through in-the-field outreach and assistance
