Wetlands Interactive Mapping

About Coastal Wetlands Data:

This site will allow you to view the Division of Coastal Management's (DCM) geographic wetlands data. Note that these data were meant to be used for planning purposes only. These wetland data are advisory in nature. They are not a substitute for an on-site determination of jurisdictional wetlands. Before viewing these data for the first time, please read our disclaimer.

Coastal Wetlands are lands that are wet at least part of the year because their soils are either saturated or covered with a shallow layer of water. Wetlands include a variety of natural systems, such as marshes, swamps, bottomland hardwoods, pocosins and wet flats. While each wetland type looks and functions differently, all wetlands share certain properties, including characteristic wetland vegetation, hydric soils and hydrologic features.

Wetlands usually are covered by plants, ranging from marsh grasses to trees. All wetland plants must tolerate living in saturated soil without oxygen during parts of the growing season. Many wetland plants are called "hydrophytes," because they can live with their roots in water.

Wetland Site Restoration & Enhancement Potential was developed by the Division of Coastal Management. This procedure uses geographic information systems (GIS) to locate potential wetland restoration and enhancement sites. It also identifies the type of wetland that could be restored or enhanced as well as the type of disturbance that has occurred at each site.

The North Carolina Coastal Region Evaluation of Wetland Significance (NC CREWS) is a watershed-based wetlands functional assessment model that uses geographic information systems (GIS) software and data to assess the level of water quality, wildlife habitat, and hydrologic functions of individual wetlands. The primary objective of the NC-CREWS wetland functional assessment is to provide users with information about the relative ecological importance of wetlands for use in planning and the overall management of wetlands. It is useful in determining where development should not be planned, or where certain types of development are best suited to and compatible with the habitat. Where wetland impacts are unavoidable, NC-CREWS can significantly improve avoidance and minimization of significant and irreversible adverse impacts to the most valuable wetland ecosystems.

Interactive Map Overview:

You can now interact with the wetlands data on the Oceanfront & Estuarine interactive map viewer.


Instructional Summary:

Turn on wetlands layers: click on the “Layers List” icon on the left-hand side of the map, then scroll down until you see the layer(s) you want to turn on.


Scale dependency: These data are viewed at maximum and minimum map scales.  If layer(s) are turned on, and the font color of the layer name is grey, not black, then you’ll need to zoom in or out more depending on current map scale.
