10 Community Rating System (CRS) The National Flood Insurance Program's (NFIP) Community Rating System (CRS) is a voluntary incentive program that recognizes and encourages community floodplain management activities that exceed the minimum NFIP requirements. As a result, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community actions meeting the three goals of the CRS: Reduce flood losses; Strengthen and support the insurance aspects of the NFIP and encourage a comprehensive approach to floodplain management Class rating system from 10 to 1 The average is Class 8 Classes are earned in 500 point increments - Money stays in the community - Insurance savings are a political plus! - Improved flood protection - Better organized programs - Evaluate vs. national benchmark - Technical assistance - Incentive to keep implementing - Public information builds constituency 10

11 Community Rating System (CRS) Premium Discount Class Points SFHA Non-SFHA 1 4,500 45% 10% 2 4,000 40% 10% 3 3,500 35% 10% 4 3,000 30% 10% 5 2,500 25% 10% 6 2,000 20% 10% 7 1,500 15% 5% 8 1,000 10% 5% % 5%

12 Community Rating System (CRS) What If? Fairfax County 6922 Policies: $2,944,803 annual premiums Average premium $425 CRS Class 9: average savings $12 ($84,323 total) CRS Class 7: average savings $34 ($235,303 total) CRS Class 5: savings $57 ($395,115 total) 12

13 Community Rating System (CRS) Uniform minimum credits give you points for activities on the state level (state laws) and make achieving a Class 9 relatively easy 18 creditable activities, organized under four categories: Public Information Mapping and Regulations Flood Damage Reduction Flood Preparation

14 Shifting from Map Mod to Risk MAP Risk MAP = Risk Mapping, Assessment, and Planning 14

15 Risk MAP Goals 1. Address gaps in flood hazard data through engineering and mapping 2. Deliver quality data to increase public awareness and leads to action that reduces risk to life and property 3. Hazard Mitigation Planning 4. Provide an enhanced digital platform 5. Align Risk Analysis programs and develop synergies X S XS Depth 15

16 Risk MAP FEMA works with communities to develop flood risk products and flood hazard maps that are: based on the best available data from the community and latest technologies conducted on a watershed basis strengthened by partnerships You can use Risk MAP tools and data to: create or improve your Hazard Mitigation Plans make informed decisions about development, ordinances, and flood mitigation projects communicate with citizens about flood risk 16

17 Flood Risk Products Traditional Regulatory Products Non-Regulatory Products (new for Risk MAP) DFIRM Database Traditional products are regulatory and subject to statutory due-process requirements Risk MAP products are nonregulatory and are not subject to statutory due-process requirements 17

18 Flood Risk Database (red = enhanced) Changes Since Last FIRM Horizontal Changes and Results Structure/Population counts impacted by change Flood Depth & Analysis Grids Depth (10, 04, 02, 01, and 0.2 percent chance) Percent Annual Chance Percent 30-Year Grid Delivery of Water Surface Elevation (multi-freq) Water Surface Elevation Change Grid (1%) Velocity Grids Multi-Frequency Depth Grids for Coastal Areas, etc. Flood Risk Assessment Average Annualized Loss 2010 Refined Flood Risk Assessment HAZUS or Non-HAZUS with improved data/assumptions Areas of Mitigation Interest Areas of Mitigation Opportunity or Awareness 18

19 Flood Risk Products and Datasets Flood Risk Database Flood Risk Assessment Data Flood Depth & Analysis Grids Changes Since Last FIRM Data Areas of Mitigation Interest Flood Risk Map Flood Risk Report Ad-Hoc Flood Risk Analyses 19

20 Flood Risk Report Increase General Flood Risk Awareness Risk Definitions and Causes Risk Reduction Techniques and Mitigation Practices Deliver Community and Project Level Results Project Results Summarized by: Communities Watershed or Project Area Provide Information to Augment or Enhance Other Efforts Local Hazard Mitigation Planning Local Emergency Management Planning Local Master Planning and Building Development 20

21 Flood Risk Map Visually Promotes Risk Awareness Contains results of Risk MAP project non-regulatory datasets Promotes additional flood risk data not shown but located within the Flood Risk Database Not a geodatabase, but a hardcopy map 21

22 Changes Since Last FIRM Identifies Areas and Types of Flood Zone Change 22

23 Using CSLF for Identifying Mitigation Actions Changes Since Last FIRM Communities and homeowners can use this to identify the revised mapping impacts on the regulatory Special Flood Hazard Area (SFHA) Also reveals new areas that may need mitigation actions either for existing assets or for future planning 23

24 Flood Depth & Analysis Grids Shows depth, velocity, and probability of flood inundation as functions of event s magnitude Serves as key inputs to HAZUS Risk Assessment Analyses Increases flood risk awareness and understanding 24

25 Using Depth and Analysis Grids for Identifying Mitigation Actions Depth and Analysis Grids Better information on depth and velocity of flooding More information on higher probability (10- & 25-year) flood events These provide enhanced data to develop a more accurate Benefit Cost Analysis (BCA) for mitigation projects, a big step towards implementation 25

26 Flood Risk Assessment Identifies flood-prone areas, and vulnerable populations and property Provides an estimate of potential damage HAZUS MH Flood Risk Assessment 26

27 Using Flood Risk Assessment for Identifying Mitigation Actions Flood Risk Assessment Identifies areas of higher flood risk by census block Quantifies potential future flood losses to existing structures Improves ability to identify areas requiring higher building code requirements Supports mitigation plan updates and disaster recovery planning through improved risk quantification 27

28 Areas of Mitigation Interest Items that may have an impact (positive or negative) on the identified flood hazards and/or flood risks Examples include: riverine and coastal flood control structures (e.g. dams, levees, coastal berms, etc.) at risk essential facilities and emergency routes that could be overtopped stream flow constrictions (e.g. undersized culverts and bridge openings, etc.) previous assistance and claims Hot Spots (clusters of IA and PA claims, RL, SRL) significant land use changes significant riverine or coastal erosion locations of successful mitigation projects 28

29 Using Areas of Mitigation Interest for Identifying Mitigation Actions Areas of Mitigation Interest Identifies areas at risk of flooding and contributing factors Assists in prioritizing areas of greatest mitigation need Identifies potential need for infrastructure upgrades and other community investments (e.g., undersized culverts) 29

30 Middle Potomac-Catoctin Watershed Study area includes all or parts of the following communities: District of Columbia Montgomery County, MD Frederick County, MD Washington County, MD Fairfax County, VA Fauquier County, VA Clarke County, VA Warren County, VA 30

31 Why Middle Potomac-Catoctin? Population Recent and projected growth Number of current and projected housing units Number of flood policies Incidence of flood claims Incidence of repetitive loss claims Number of repetitive loss properties annually Number of declared flood disasters Availability of recent data 31

32 Discovery Map: Flood Risk 32

33 Discovery Map: Potential Loss 33

34 Discovery Map: Mapping Needs 34

35 Data We Need from You Completed Data collection Questionnaire Completed Discovery meeting questionnaire with GIS contact Areas of Concern Areas of recent or planned development Areas of high growth or other significant land changes Areas of historical flooding Other flood risks Mitigation projects Your ideas about Risk MAP products and mitigation projects that may help your community To explain some of the actions that your community may take to reduce risk, we ll review mitigation grants and planning 35

36 Hazard Mitigation Builds Sustainable, Resilient Communities Sustainability meets the needs of the present without compromising the ability of future generations to meet their own needs Indicators of sustainability are social, economic, and environmental health Sustainable communities minimize exposure of people and property to risk by planning for and mitigating against natural disasters Sustainable communities are disaster-resilient! 36

37 Hazard Mitigation Planning Risk MAP and Mitigation Planning Refer to the Plan & Keep it Current Coordinated and participative Planning Process Mitigation Planning Cycle Identify hazards that can affect the jurisdiction Local hazard mitigation plans must be updated every five (5) years. Use new Risk MAP information to update local HMP. Flood Hazard Profile Risk Assessment Mitigation Strategy Adopt the plan and implement the mitigation strategy Assess the risks from these hazards Develop strategy to mitigate the risks 37

38 Actions to Mitigate Flood Risk 38

39 Possible Mitigation Activities 1 foot of freeboard for new structures Cumulative substantial improvement clause List of community-owned buildings that have flood risk Acquisition of flood prone structures. County drought plan County GIS system Updated weather tracking equipment Stream bank stabilization projects Identified sanitary sewer mains vulnerable to erosion from flood Annual cleaning of streams and stormwater management ponds Adopted a wellhead protection ordinance Vulnerability assessment of water and wastewater infrastructure Elevate, move, and acquire flood damaged structures Identify vulnerable critical facilities Implement mitigation measures for repetitive loss properties Require elevation of new structures and substantially improved structures Restore stream channels 39

40 Unified Hazard Mitigation Assistance Grant Programs Grants and State/County Projects for the implementation of mitigation activities and projects Hazard Mitigation Grant Program (HMGP) Available after a major disaster declaration - the amount of funding is 15% of the total federal assistance provided by FEMA for disaster recovery under the major disaster declaration. 40

41 Mitigation Grant Programs Pre-Disaster Mitigation (PDM) Grant Program Nationally competitive grant program that funds cost effective, comprehensive hazard mitigation activities prior to a disaster event that reduce injuries, loss of life, and damage to property Severe Repetitive Loss (SRL) Purpose is to reduce/eliminate the risk of flood damage to these residential properties and the associated drain on the National Flood Insurance Fund (NFIF) from the flood insurance claims associated with these properties. 41

42 Mitigation Grant Programs Repetitive Flood Claims (RFC) Nationally competitive grant program established to reduce the risk of flood damage to structures insured under the National Flood Insurance Program (NFIP) that have had one or more claim payments for flood damages Flood Mitigation Assistance (FMA) Provides funding to assist States and communities in implementing measures to reduce or eliminate the long-term risk of flood damage to buildings, manufactured homes, and other structures insured under the NFIP 42

43 Risk Communication Federal/State/Commonwealth/Local goals: To ensure safer communities and reduce risk to life and property To effectively communicate risk and increase public awareness, leading citizens to make informed decisions regarding their risk Key factors contributing to successful achievement of these goals are: Community engagement and exchange of flood risk information Effective collaboration through partnerships Strategic communications plan development 43

44 Risk Communication FEMA is committed to: Collaborating closely with communities within the Middle Potomac-Catoctin Watershed to accurately portray risk Engaging the community throughout the project timeline Using the best and most recent data and information available 44

45 Discovery Project Charter Details the community s long-term vision for the watershed Describes the mapping, assessment, and planning information, products, and assistance that FEMA will provide Summarizes local flooding concerns and indicates areas where floodplain changes are expected Describes the roles and responsibilities of FEMA and the community 45

46 Next Steps Communities will provide additional data FEMA will: finalize Discovery Map and Discovery Report and distribute to communities and other stakeholders update FEMA systems (Coordinated Needs Management Strategy, National Digital Elevation/Orthophotography Programs, etc.) prepare Scope of Work for any Risk MAP projects Communities and FEMA will coordinate regarding Project Charter or other agreement regarding community s contribution to project 46
