Flood Resilience Planning Resources

Flood Hazard Data

Understanding flood risk requires knowing which areas of your community are exposed to flooding today, and which areas are expected to be exposed in the coming decades. Due to changing patterns of precipitation, sea level rise, and development, historic flooding trends are no longer a useful predictor of future risk.

Nationwide, we lack consistent, locally specific data that forecasts flooding based on multiple risk sources. The Commonwealth is closing these data gaps and providing data tools to support flood resilience planning efforts in Virginia.

DCR flood data

DCR provides two non-regulatory flood hazard datasets that can be used together with regulatory data to support more informed flood resilience planning: a coastal Virginia flood hazard dataset (developed for the Coastal Resilience Master Plan) and a statewide Fathom flood hazard dataset (procured for the Virginia Flood Protection Master Plan). The table below explores and compares these two resources.

	Coastal Virginia Flood Hazard Data	Fathom Flood Hazard Data
*Geographic Area*	Coastal: localities within any of the eight easternmost Planning District Commissions in Virginia.	Statewide: The entire Commonwealth of Virginia.
*Flood Hazards*	Coastal, riverine, and rainfall-driven flooding	Coastal, riverine, and rainfall-driven flooding
*Recurrence Intervals*	Seven recurrence intervals: 1 in 2-, 5-, 10-, 25-, 50-, 100-, and 500-year. Three tidal conditions (MLW, MHW, 1.5xMTR) are also available for coastal flood data.	*Five recurrence intervals:** 1 in 10-, 25-, 50-, 100- and 500-year.
*Associated DCR Plan*	Coastal Resilience Master Plan (CRMP)	Virginia Flood Protection Master Plan (VFPMP)
*Planning Scenarios*	Five planning scenarios: baseline (2020), plus “moderate” and “high” scenario options for the near future (2030-2060) and far future (2060-2100) time horizons.	Five planning scenarios: baseline (2020), plus two “moderate” and “higher” scenario options for the 2060- and 2100-time horizons.
*Basis for Future Conditions*	Varies by flood source and planning scenario. See reference figure for more information.	Shared Socioeconomic Pathway 2-4.5 (SSP2-4.5). “Moderate” scenario based on median (50th percentile) values and “higher” scenario based on 83rd percentile values.

*Virginia government entities and state-recognized Tribal governments may sub-license all Fathom data from DCR for a 12-month renewable license term. To inquire about a sub-license agreement, including data use limitations, please contact us at flood.resilience@dcr.virginia.gov.

Other flood data

Additional data to visualize and understand flood hazards is available through state and federal platforms. Below is a snapshot of these data resources which can be accessed through the links provided.

FEMA Flood Hazard Data via DCR’s Hệ Thống Thông Tin Nguy Cơ Lũ Lụt Virginia (virginia Flood Risk Information System) (VFRIS) – VFRIS compiles and displays flood hazard data from the Federal Emergency Management Agency (FEMA) including Special Flood Hazard Areas. It also provides access to links to download FEMA Flood Insurance Studies, FEMA HEC-RAS Models. These maps also display non-regulatory flood hazard data including data from and data do not incorporate future-looking projections based on changing precipitation patterns, new development or compound flood risk from tidal flooding events.

National Hurricane Center’s Storm Surge Risk Maps – includes data viewers and data downloads based on modeling which forecasts the extent and depth of storm surge resulting from hurricanes (category 1-5) for the Virginia coast.

NOAA 2022 Sea Level Rise Technical Report – provides nationwide forecasts for sea level rise through 2150. The report provides more recent forecasts than were included in DCR’s coastal resilience web explorer and Phase I of the Coastal Resilience Master Plan. NOAA’s Sea Level Rise Viewer allows users to map and download the data.

NOAA Mid-Atlantic RISA Projected IDF Curve Data Tool – county-level tool for forecasting changes in precipitation depths from historic ATLAS-14 modeling to two future conditions (2020-2070 and 2050-2100) under two emissions scenarios (RCP 4.5 and RCP 8.5). The model forecasts precipitation change across six average recurrence intervals (2-year to 100-year) and 14 durations (5 minute to 7 day).

Tools for Planning

There are many tools to aid organizations in crafting a flood resilience plan. Below is an abbreviated list of useful planning tools. Additional tools can be found on the information gateways linked below.

Tools specific to Virginia

The following tools were developed with Virginia-specific needs in mind. While some are focused on exploring flood resilience specifically, others support resilience planning more broadly.

CFPF Resilience Plans - a DCR-approved Resilience Plan is required for localities submitting applications in the "project" category of the Community Flood Preparedness Fund. The requirements for an approved resilience plan can be found in Appendix F of the CFPF Grant Round 6 draft manual.

ADAPT VA – an information gateway on climate change adaptation for individuals, local programs, and agencies in Virginia. The website provides a variety of resources such as short and long-term sea level curves and maps, flood mapping and decision-support tools, legal and policy resources, and stories that explain adaptation through maps and pictures.

Proactive Planning for Resilience: Protocols for Community-Led Climate Adaptation Planning in Virginia – a Virginia-specific guide for climate adaptation planning for decision-makers across the Commonwealth. The website outlines steps for developing a plan, with detailed case studies, definitions, tools, legal considerations and best practices.

The RAFT and PREP Tool – The Resilience Adaptation Feasibility Tool (RAFT) Team is a Virginia state university partnership which brings capacity building and technical assistance to local governments over a period of 18 months to help build their resilience. Their team’s PREP Tool provides access to the RAFT’s methods and approach for assessing local government capacity for resilience and identifying and prioritizing projects to implement.

Federal Tools

Federal agencies have developed tools to assist organizations to plan and implement successful flood resilience strategies. The following resources may help you to craft your resilience plan.

US Climate Resilience Toolkit – a national portal that includes a variety of tools for building resilience to flooding impacts, including the Steps to Resilience Framework, which outlines a straightforward process for creating a resilience plan alongside resources to use to get there.

USACE’s International Guidelines on Natural and Nature-Based Features for Flood Risk Management – consolidates best practices for constructing natural and nature-based features for flood risk management into a guidance document for decision-makers and practitioners to use when considering these practices in flood resilience plan development.

US DOI Nature Based Solutions Roadmap – outlines information on nature-based solutions, including specific strategies, considerations for implementation, co-benefits, examples, and resources.
