Flood Risk Tools for WatershedsFlood Risk Tools will be prepared for all communities within a Discovery Watershed: Flood Risk ReportFlood Risk MapFlood Risk AssessmentFlood Risk Database

#FEMA provides tools for communities to use to better understand the natural hazard risks their communities face. These tools can assist communities in preparing hazard mitigation plans, communicating about flood risks with residents and business owners and creating a platform to discuss strategies with other community officials to minimize future risks due to natural hazards. These tools including datasets, a database, narrative report and maps are commonly referred to as non-regulatory flood assessment and risk datasets and non-regulatory products. These products will be prepared for all communities within a Discovery Watershed and delivered at the conclusion of the Discovery effort.

3Flood Risk Report (FRR)

Provides summary of flood risk within watershed or project areaParallels the Flood Insurance Study (FIS)Includes maps, data, and risk assessment information that may be included in the hazard mitigation planProvides risk assessment on both the community and watershed levelUseful for risk communication and outreach

#The Flood Risk Report (FRR) provides local communities with a summary of their flood risk developed during a flood risk project that can be used for outreach and communications and to supplement or improve the mitigation plan risk and vulnerability assessments.

The data can also be used to support development of mitigation strategies and actions. The FRR provides watershed-specific and/or community-specific flood risk information to help local officials develop and prioritize meaningful mitigation strategies. 4Flood Risk Map (FRM)Visually depicts areas with the greatest flood riskProvides specific areas of focusEmphasizes risk reduction activities that may impact the watershedDepicts interrelation of flooding issues across jurisdictional borders

#The Flood Risk Map can be one or more of the maps presented at the Discovery meeting.They can be used to begin discussions at the local and watershed level about natural hazard risk and identifying solutions.These maps can be used in presentations at local government meetings and as visual displays when talking to residents.They are also useful tools that can provide insight and support to hazard mitigation plans.

5Flood Risk AssessmentImproves ability to identify areas requiring higher building code requirements or use of flood resilient designs and construction materialsIdentifies areas of higher flood risk by census blockProvides valuable data for mitigation plans vulnerability assessmentSupports disaster recovery planning by showing areas of highest expected damages

#Building on the foundation of the 2010 nationwide HAZUS Level 1 Average Annualized Flood Loss (AAL) Study, basic refined HAZUS loss estimation analyses will be done for flooding sources with default HAZUS building stock information. Where local building environment data is available, enhanced HAZUS or other risk assessment analyses are possible. Communities are encouraged to pursue enhanced analyses when possible by providing FEMA with additional GIS data such as parcel data, building footprints, or elevation certificates.

FEMA offers training courses in both classroom and virtual settings to equip community officials to use the Hazus- Multi Hazard tools in order to deliver a knowledgeable plan of action back to the community. More information on both of these course offerings is available at www.fema.gov/hazus-training. The curriculum track of courses leads to a certificate as a Hazus Trained Professional or Hazus Practitioner.

6Flood Risk AssessmentEstimates value of potential future flood losses to existing structuresImproves ability to identify and prioritize effective mitigation actionsSupports mitigation plan updates and disaster recovery planning through improved risk quantificationProvides valuable data for mitigation plans vulnerability assessment

Flood Risk Assessment Data

#The Flood Risk Assessment assists communities in understanding the financial impacts associated with flood damage. The data provides information regarding estimates of potential flood losses for different flood scenarios and reports the results by census block (U.S. Census Bureau). Communities may also provide additional funding to support analysis enhancement. The results of both the basic refined and enhanced HAZUS analysis can be incorporated into hazard mitigation plans.

7Flood Risk DatabasePrimary source to access information collected and developed during the flood risk assessment processParallels the Flood Insurance Rate Map databaseProject-level databaseRequires GIS software to fully utilize

#The Flood Risk Database is a product that contains the raw data and results from the Flood Risk Assessment analysis.

For all Risk MAP studies it will contain the project-area results of the following Flood Risk Assessment data:

Averaged Annualized Loss (AAL) using Hazus for the entire project areaRefined Hazus results for areas restudiedComposite Flood Risk AssessmentAnalysis Required for Flood Risk Assessment Data in the Flood Risk ReportAnalysis Required for Flood Risk Assessment Data in the Flood Risk Maps

There may be additional datasets included in the database when they were developed as part of the study.

Communities can use local data such as, basemap data or parcels, to combine datasets and create ad hoc uses for the Risk MAP datasets in their local area.FEMA will publish and maintain the database in a standardized form to support national, State, regional, and local distribution. 8Risk MAP Non-Regulatory Products and Hazard Mitigation PlanningFEMA encourages local governments to develop and continually refine Hazard Mitigation PlansTo increase public and political support and commitment for mitigation To be eligible for Hazard Mitigation Assistance grantsUse Risk MAP tools to update your Hazard Mitigation Plan and build a more Resilient community!

#The goal of mitigation is to reduce or eliminate the long-term risk to people and property from natural hazards and their effects. A comprehensive risk analysis provides the factual basis for activities proposed to reduce losses in determining effective mitigation strategies. The Flood Risk Tools described here and additional product and datasets can provide Planners with information critical to such analysis. They can be used both pre- and post-disaster to reduce the loss of life and property, enable rapid recovery from disasters, lessen the financial burden on homeowners and communities, protect the natural environment, and support resilient communities.

9Additional Information for Community OutreachRisk Communications Guidebook for Local Officials - http://www.riskmap6.com/guidebook.aspxFact SheetsWeb-based Key Messages for local officials http://riskmap2go.riskmap6.comwww.riskmap6.com

#Risk communication, specifically local education and outreach efforts, promote a community prepared for the natural hazards it interacts with. People cannot plan for risks they are unaware of and residents and business owners look to their local officials to communicate individual and community actions that can be taken to reduce risk.Interaction with community residents provides opportunities for local officials and staff to communicate with stakeholders and citizens about the natural hazard risk. To assist with this critically important task, risk communication tools, fact sheets and customizable templates were created to share information through traditional and non-traditional outreach methods.

FEMA Region 6 has developed a Guidebook that will assist with internal communication efforts with other departments and elected officials, as well as with residents, business owners, the media and local stakeholders - such as lenders, insurance agents, and real estate professionals. The Guidebook is available on riskmap6.comOn our FEMA Region 6 project website riskmap6.com, the latest fact sheets and other outreach materials can be found on the Resources and related links tab.FEMAs latest key messages for a variety of Risk MAP topics are kept up to date on our web-based mobile application Riskmap2go.

#The mission of FEMA is to support communities in becoming more disaster resilient by knowing their risk, planning for that risk, and mitigating and communicating about these risks.Everyone can take action to reduce their risk. FEMA encourages local officials, citizens and stakeholders to use these flood risk tools, products and datasets to understand their risk and make informed choices for their community, families and property.
