DCR ORP Public File Repository

The Virginia Department of Conservation and Recreation’s Office of Resilience Planning maintains this public file repository to provide access to flood resilience open data products. The repository is designed to house public data produced for the Virginia Coastal Resilience Master Plan (CRMP), Virginia Flood Protection Master Plan (VFPMP), and other purposes. At present, the repository hosts only data products produced for the CRMP Phase II (2025) and Phase I (2021).

AVAILABLE DATA PRODUCTS: 

Public CRMP data available to browse through this repository is nested under various folders, grouped by the type of flood hazard: coastal, pluvial (rainfall), fluvial (riverine) or combined hazards.  

Available coastal flood hazard spatial data includes depth grids, depth grids with wave effects, graduated floodplains, water surface elevation, and the associated terrain digital elevation model as raster files. Graduated floodplain data is also available as a vector file.  

Combined flood hazard spatial data is provided to document the 1% Annual Exceedance Probability (AEP) floodplain extent across coastal, fluvial and pluvial data across all planning scenarios modeled for the plan. Spatial data is available as rasters that display hazards by dominance (deepest flood type) or presence (all flood types present). 

Fluvial (Riverine) flood data was collected from FEMA for the CRMP Phase II in 2024. It is available as a geodatabase containing polygons for the FEMA Special Flood Hazard Area (SFHA) with coastal flood zones (e.g. Zone V, VE) removed to isolate the riverine-dominant flood zones. 

Pluvial (Rainfall) flood data includes spatial data and the HEC-RAS models used to generate that data. Information about the methodology used to produce the pluvial hazards data and use cases for applying the data are also available as PDFs. Spatial data is provided via pluvial hazard graduated floodplain rasters using the CRMP Phase II planning scenarios and return period events. Spatial data is also provided via a variety of pluvial flood depth grid products, available either as the direct products used for the CRMP Phase II (in other words, aligned with the CRMP Phase II planning scenarios and return period events), or by generic 1-inch precipitation depth intervals. Additional raster data is available for pluvial model inputs, including the curve numbers and Manning’s N values.  

Users can also access the HEC-RAS models used to develop the available pluvial flood spatial data products used for the CRMP Phase II. However, it is recommended that users seeking to access these models or the 1-inch precipitation depth intervals products use the DCR Pluvial Model Catalog rather than navigating to those products via the repository folders: https://floodplan-vdcr.hub.arcgis.com/apps/6887359c29e744a2bc08c0783235c496.  

Coastal flood impacts data is available via the repository but is not recommended for use, as it is only available for the Phase I (2021) plan. Users are instead encouraged to access Phase II (2025) tabular impacts data by visiting the Coastal Resilience Web Explorer. 

HOW TO USE THIS DATA:  

DCR’s Office of Resilience Planning is available to assist government entities in need of support to apply the plan’s data to their work. Please contact us at flood.resilience@dcr.virginia.gov with any questions or requests for assistance.  

Opportunities to use the data provided include:  

• Understand challenges of increased flooding that may be relevant to your organization or geography of interest. 

• Develop locally specific or sector-specific plans that incorporate and adapt the forward-looking flood hazard and impact data. For example, comprehensive plans, small area plans, hazard mitigation plans, capital improvement plans, and more.   

• Identify opportunities to coordinate with others based on mutual needs and priorities.

• Fill flood resilience gaps in areas where flood risks exist and identified projects or initiatives are insufficient to build resilience.  

• Incorporate flood resilience information into regular business operations to support enhanced decision making on an ongoing basis. 

• Seek funding and policymaker support to address flood risks and build resilience.  

• Educate public audiences about flood risks and resilience using the CRWE and Open Data Portal.
