Wetland Restoration Opportunities, HUC 10, Chesapeake Bay Watershed
- Description:
- This dataset represents wetland restoration opportunities as well as wetland enhancement opportunities. Potential restoration opportunities are places that are not currently wetlands but have the potential to be restored to wetlands (based on presence of hydric soils or being located within tidal areas). Enhancement opportunities are all places that currently are wetlands.
The restoration opportunities were created for both tidal and non-tidal wetlands. For tidal wetland restoration opportunities, the USGS Digital Elevation Model was used to establish the potential boundaries from 2 m above mean sea level to 0 m. For non-tidal wetland opportunities, the boundaries of the Chesapeake Bay Program hydric soils layers were used as potential project extent. Within these regions, the following classification categories were removed from the high resolution dataset: 1. impervious non-road, 2. forest, 3. impervious roads, 4. water, 5. tree canopy over impervious surface, and 6. three wetland categories. These 6 classifications were removed because land uses are either already wetlands or are land uses that could not be restored as wetlands. The areas that remained could potentially be restored as tidal or non-tidal wetlands.
The enhancement opportunities layer was developed by selecting the following three classification categories from the high resolution land cover dataset: non-tidal floodplain, tidal wetlands, non-tidal other wetlands. All existing wetlands are proposed as potential wetland enhancement opportunities.
Data are displayed as total acreage of opportunity in each HUC 10 and are classified into 5 groups utilizing the Jenks (Natural Breaks) method in ArcGIS.

- Use Constraints:
- The distributor shall not be held liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document. It is strongly recommended that this data is directly acquired from the distributor and not indirectly through other sources which may have changed the data in some way. These data should not be used at scales greater than 1:24,000 for the purpose of identifying hydrographic watershed boundary feature locations in the United States. The Watershed Boundary Dataset is public information and may be interpreted by all organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application of the data. Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can result in misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the small scale. Digital data files are periodically updated and users are responsible for obtaining the latest version of the data from the source distributor. Acknowledgment of the origination agencies would be appreciated in products derived from these data.
