Title:

Target Areas for the Creation of New or Restoration of NNBFs in Coastal Virginia

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

Polygons depict areas where vulnerable buildings (i.e., buildings on ground that is less than 10-feet in elevation) receive no benefits from NNBFs. These are areas where localities or landowners may consider creating new or restoring NNBFs to provide multiple benefits to communities.

Purpose:

This layer identifies target areas where the creation or restoration of NNBFs (natural and nature-based features) would provide multiple benefits to communities, including tidal flooding mitigation benefits for buildings at less than 10-feet in elevation along coastal Virginia.

Process_Step:

Process_Description:

Identify building IPs with no intersecting NNBFs. These are "0 NNBF IPs."

Process_Date: 20190701

Process_Step:

Process_Description:

Intersect 0 NNBF IP lines with the shoreline and buffer these points by 100-feet. Overlapping adjaced polygons were dissolved into one target feature.

Process_Date: 20190902

Process_Step:

Process_Description:

For each target area, count the number of IPs intersecting. Some target areas intersect multiple building IPs.

Process_Date: 20190916

Process_Step:

Process_Description:

Add information regarding the land cover classes within the target area, and what existing NNBFs are currently adjacent to the target area.

Process_Date: 20190918

Process_Step:

Process_Description:

Add information from CCRM's Shoreline Management Model that provides information regarding existing shoreline erosion control structures (e.g., bulkheads) and recommended erosion control practices along shorelines.
