Title: Potential 2050 Wetlands (wetlands that meet the RPA criteria)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Purpose:
This polygon layer is the potential 2050 wetlands that meet RPA (resource protection area) criteria. Future projections were based on the NOAA 2017 Intermediate-High sea level rise curve for the year 2050. The definition of wetlands was based on the Chesapeake Bay Preservation Act (CBPA) which states they are those tidal wetlands, and those non-tidal wetlands that are connected by surface flow and contiguous to tidal wetlands or water bodies of state waters. This does not include current or future non-tidal isolated wetlands, such as those seen in NWI (National Wetlands Inventory).
A multi-step GIS methodology was developed to migrate tidal wetlands along the current shoreline inland to areas that potentially will be wetlands in 2050. Wetland polygons from several sources were used to identify the potential 2050 wetlands; these include the Tidal Marsh Inventory (CCRM), National Wetlands Inventory (NWI), Thiessen polygons generated from the shoreline to the upland extent of future tidal wetlands (1.5m elevation), and a GIS-generated stream network using lidar data .
This data layer was developed by the Center for Coastal Resources Management for a project to provide information on the projected location (extent and position) of certain RPA features to inform resiliency assessments as required by CBPA legislation and regulation. This layer is served on <http://adaptva.com/> and additional information can be found in a CCRM final report entitled "New Guidance to Build Resiliency and Mitigate for Sea Level Rise as Elements of the Chesapeake Bay Preservation Act" for NOAA Coastal Zone Management, November 2022. The report is available at https://scholarworks.wm.edu/reports/2839/.
