National Flood Insurance Program & Risk MAP Program
National Flood Insurance Program U.S. Congress established the National Flood Insurance Program with the passage of the National Flood Insurance Act of 1968 Community adopts and enforces a floodplain management ordinance to reduce flood risk to new and existing development in mapped floodplains Federal government makes flood insurance available to property owners in participating communities For more information on the NFIP visit www.fema.gov 5
Mitigation Division Our Mission Working in partnership to support sustainable, disasterresilient communities, to avoid or reduce the loss of life, loss of property, and financial impact of hazards. Three Branches Risk Analysis Floodplain Management & Insurance Hazard Mitigation Assistance 6
Risk MAP Vision To deliver quality data that increases public awareness and leads to action that reduces risk to life and property Objective (Coastal) To provide updated flood hazard data for 100% of the populated U.S. coast 7
San Francisco Bay Area Coastal Study
San Francisco Bay Area Coastal Study Contra Costa County is part of a larger study of the entire San Francisco Bay 9
Contra Costa County Bay Area Coastal 10
Contra Costa County Bay Area Coastal Updated coastal hazards for the Contra Costa County shoreline to reflect existing hazards Previous 2009 effective Flood Insurance Rate Map panels relied on the 1985 United States Army Corps of Engineers Study for coastal hazards No riverine analysis was completed Coastal to effective riverine tie-in used higher of the two hazards No Appeals Received Proof panels 0093 and 0094 were issued for the City of Concord to better represent the riverine/coastal tie-in 11
Bay Area Coastal Area of Mitigation Interest - Antioch 2009 FIRM: Zone AE 9 along Bay shoreline 2014 BAC Study Preliminary FIRM: Zone AE 9 12 along Bay shoreline The coastal analysis results for Transects 1 thru 13 are higher than 11.2 feet. In order to achieve a reasonable tie-in with the effective mapping of 9 feet at Transect 1, the BFEs were reduced in this region. The actual flood risk may be higher than mapped in this region. * Steep-sloped shorelines and shoreline structures (e.g. steep revetments, vertical walls) were analyzed with wave run-up; shallow-sloped shorelines and inland topography (e.g., marshes, developed areas) were analyzed with overland wave propagation, or WHAFIS. 12
Bay Area Coastal Area of Mitigation Interest - Pittsburg 2009 FIRM: Zone AE 9 10, with some Zone A along the Bay shoreline 2014 BAC Study Preliminary FIRM: Zone AE 10 12, with some Zone A along the Bay shoreline * Steep-sloped shorelines and shoreline structures (e.g. steep revetments, vertical walls) were analyzed with wave run-up; shallow-sloped shorelines and inland topography (e.g., marshes, developed areas) were analyzed with overland wave propagation, or WHAFIS. 13
Bay Area Coastal Area of Mitigation Interest - Richmond 2009 FIRM: Zone VE 9 and along the Bay shorelines 2014 BAC Study Preliminary FIRM: Majority of Richmond as Zone AE 10, with Zone VE 11 17 along the Bay shoreline * Steep-sloped shorelines and shoreline structures (e.g. steep revetments, vertical walls) were analyzed with wave run-up; shallow-sloped shorelines and inland topography (e.g., marshes, developed areas) were analyzed with overland wave propagation, or WHAFIS. 14

Hazard Mitigation Planning
Mitigation What is Hazard Mitigation? Any sustained action taken to reduce or eliminate long-term risk to human life and property from hazards Why are Hazard Mitigation Plans Important? Foundation for a long-term strategy to reduce disaster losses and break the cycle of disaster damage, reconstruction, and repeat damage Provides a framework for risk-based decision making involving stakeholders and the public. Creates opportunities for grant funding. 45
Unified Hazard Mitigation Grant Assistance 1. Pre-Disaster Mitigation (PDM) Can apply to mitigation of any hazard, not just flood 75%/25% cost share What s available depends on amount appropriated by Congress each year; no Presidential Declaration needed Nationally-competed 2. Flood Mitigation Assistance (FMA) Flood mitigation projects Includes repetitive loss structures with rep loss strategy - 90%/10%. Severe rep loss structures get 100% funding, other projects 75%/25% cost share Funding comes from flood insurance policy premiums, allocated to each state 3. Hazard Mitigation Grant Program (HMGP) Usually funds larger mitigation projects, not only flood 75%/25% cost share Funding becomes available after presidentially-declared disaster and is15% of the total Federal funding given to a state for a disaster All 3 require FEMA approved Local Hazard Mitigation Plan 46
General Requirements for All Hazard Mitigation Projects Must be cost-effective Technically feasible and effective Meet Environmental Planning and Historic Preservation requirements in accordance with HMA Unified Guidance Must adhere to all relevant statutes, regulations, and requirements including other applicable Federal, State, Tribal, and local laws, implementing regulations, and Executive Orders All Applicants and sub-applicants (now called recipients) must have hazard mitigation plans that meet the requirements of 44 CFR Part 201. 47
HMA Eligible Activities Eligible Activities The table below summarizes eligible activities that may be funded by HMA programs. Detailed descriptions of these activities can be found in the HMA Unified Guidance. ELIGIBLE ACTIVITIES Mitigation Activities HMGP PDM FMA Property Acquisition and Structure Demolition or Relocation 48 Structure Elevation Mitigation Reconstruction Dry Floodproofing of Historic Residential Structures Dry Floodproofing of Non- Residential Structures Minor Localized Flood Reduction Projects Structural Retrofitting of Existing Buildings Non-Structural Retrofitting of Existing Buildings and Facilities Safe Room Construction Wind Retrofits Infrastructure Retrofit Soil Stabilization Wildfire Mitigation Post-Disaster Code Enforcement Generators Advance Assistance Management Costs = Mitigation activity is eligible for program funding 5% Initiatives Hazard Mitigation Planning
Hazard Mitigation Plans The purpose of hazard mitigation planning is to identify policies and actions that can be implemented over the long term to reduce risk and future losses. Mitigation Plans form the foundation for a community's long-term strategy to reduce disaster losses and break the cycle of disaster damage, reconstruction, and repeated damage. With a HM Plan you are eligible for more federal disaster aid after a presidential declaration. Requirement for all FEMA grants! 49
