Data to Support Coastal Adaptation & Resiliency
The following geospatial datasets and mapping viewers can help inform many types of activities including comprehensive and hazard mitigation plan updates, vulnerability assessments; stormwater or parks and recreation plans development; flood zone workshops, and other events serving both technical and general audiences.
These data sources should supplement the current and most accurate data found at the local level in the different municipal or county departments (e.g., planning, geographic information systems (GIS), public works, parks and recreation, etc.). If using data to support policy or other programs, be sure to examine, understand, and be transparent about the metadata or 'data about the data' such as source, resolution, geographic projection, update frequency, etc.

Environmental:
- Coastal Wetlands (N.C. DCM)
- Estuarine shoreline, oceanfront and inlet, static vegetation and setbacks (N.C. DCM)
- This information is now included in DCM's Interactive Map Viewer.
- Sea level rise scenarios of 1ft to 6ft (NOAA)
Infrastructure:
- Building footprints (including first-floor elevations), flood zones, digital elevation models/LiDAR (N.C. Emergency Management)
- Requires creating a free account to log in and access data
Social Vulnerability:
Social vulnerability, often expressed as an index, can be measured by and consist of a variety of different factors (e.g., unemployment, household income, race and ethnicity, etc.). Before incorporating or using the data below, we recommend visiting the social vulnerability section of the Planning and Policy page.
- NOAA's Social Vulnerability Index (SoVI) for N.C. Census Tracts (2010 Census Data)
- CDC's Social Vulnerability Index (SVI) for U.S. Census Tracts (Sortable Annual Data)

NOAA, USGS, & Others:
- NOAA Digital Access Viewer: explore and select relevant land cover, imagery, and elevation data.
- USGS Total Water Level and Coastal Change Forecast Viewer: explore forecasts of total water level for the next several days in your area along the coast ahead of major storms.
- USGS Coastal Change Hazards Portal: Explore and download data related to changes from extreme storms (hurricanes, nor'easters), shoreline change (short- and long-term, position), and sea level rise.
Generating community support to explore and make tough decisions about investing in long-term resilience requires proof or evidence that the action will have a positive impact on the economy, environment and/or society. While being able to document and provide a detailed and inclusive cost-benefit analysis using local data is ideal, sometimes communities must rely on evidence or statistics that are based on work done regionally or nationally. The data summaries and associated infographics below can serve as reliable information that can back up the argument being made to take certain actions towards adaptation and resilience.
- NOAA Coastal County Snapshots: Access count-specific data about flood exposure (e.g., demographics, infrastructure, and environment within the flood zone), ocean jobs (e.g., the economic value of ocean-dependent jobs), and wetland benefits (e.g., contributions to safer, cleaner, and more economically productive communities).
- NOAA Coastal Fast Facts: View relevant national statistics and infographics for use in presentations or discussion to help make the case for investing in coastal resilience.

- Key Messages:
- Mean annual temperature has increased by almost 1 degree Fahrenheit since the beginning of the 20th century. Under a higher emissions pathway, historically unprecedented warming is projected by the end of the 21st century.
- The number of landfall hurricanes in North Carolina is highly variable from year to year. Hurricane-associated storm intensity and rainfall rates are projected to increase as the climate warms.
- A large portion of North Carolina's coastline is extremely vulnerable to projected sea level rise due to its low elevation and subsidence of land in the northern part of the Coastal Plain. By the end of the 21st century, global sea level is projected to rise 1-8 feet, with a likely range of 1-4 feet.
