1 San Francisco Bay Area Coastal Study Inaugural Bay Area FMA Luncheon March 13, 2013

2 California Coastal Analysis and Mapping Project Two Companion Large-Scale Efforts: San Francisco Bay Area Coastal Study Open Pacific Coast Study Re-study flood risk along the open coast and inland bays of all California coastal counties Re-map the elevation and inland extent of wave-induced coastal flooding 2

3 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 3

4 Comprehensive & Collaborative Covers 100% of the San Francisco Bay coastal communities in 9 counties Leverages latest 2010 NOAA and USGS LiDAR topographic data Regional hydrodynamic, storm surge, and wave modeling Detailed onshore coastal hazard analysis Outreach, coordination and collaboration with numerous partners, stakeholders, and other studies 4

13 Flood Risk Review Meeting

14 Flood Risk Review Meeting Provide an overview of the National Flood Insurance Program (NFIP) and Risk MAP Provide an overview of the San Francisco Bay Area Coastal Study Discuss coastal study process and methodology Review and discuss the draft Work Maps and the online tool for review and comments Discuss how the products can inform decisions to reduce flood risk Learn how to communicate about flood risk using the products and datasets Answer questions 14

15 On-line Work Map Review Tool 15

16 Tool Overview Post draft Work Maps online at r9coastal.org for community review Accommodate community staff need to review data beyond the meeting timeframe Reduce paper map products from the workflow and reduce the potential for lost comments 16

17 Comment Process Users will be provided a unique login and password Communities will have 30 days to review the Wwork Maps All comments will be recorded and archived Comments will be taken into consideration as the mapping enters production 17

18 After the Flood Risk Review Meeting FEMA Finalize the analyses and mapping and post it on-line at for community review Produce Preliminary Maps and hold Preliminary FIRM/Open House Meeting Community Officials Review and Comment on the maps Tailor outreach plan template Begin communicating about flood risk Initiate hazard mitigation planning 18

23 Flood Risk Awareness Surveys Nationwide, Research-based FEMA surveyed local officials in 2010 to: Provide a baseline of flood risk awareness Inform national outreach and community engagement activities FEMA conducted a second survey in 2011 to track progress toward its awareness goals: Public awareness and understanding of risk management Local official awareness of flood risk within Risk MAP project areas 23

24 Survey Says The following tools would make it easier for local officials to share flood risk information with the public: Information to add to community websites Publications for building owners on reducing risk Customizable letters or brochures Media materials such as draft press releases 24

25 Tools, Templates and Products Tools & Resources FEMA website - library Mapping, LOMC guidance docs, flood insurance, floodplain management FEMA-MAP Study Brochures Coastal Beat Templates Community Outreach Plan Template Press release Open House Materials Non-regulatory Products Changes Since Last FIRM 25

26 Hazard Mitigation Planning What is Hazard Mitigation? Any sustained action taken to reduce or eliminate longterm 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. 26

27 Hazard Mitigation Planning How is Hazard Mitigation Planning relevant to SF BAC Study? Results of the Study (FIRMs) enable communities to Identify Risk, the first step in the Risk MAP Life Cycle Mitigation Planning provides the framework to carry out the remaining 3 steps in the Risk MAP Life Cycle using Study results Assess Risk and Vulnerability using Coastal Flood Hazard Information/Data Communicate Risk through public involvement increases education and awareness of Hazards and Risks Mitigate Risks by identifying actions and aligning them with other community objectives 27

28 Hazard Mitigation Planning Process Communities with Lapsed or No Plans 1. Organize Resources 2. Assess Risks 3. Develop Mitigation Plan Communities with Approved and Adopted Plans 4. Implement Plan and Monitor Progress 28

29 Hazard Mitigation Planning Resources FEMA ( Laws, Regulations, Guidance, Policies How-To Guides Mitigation Grant Funding Programs Training Cal EMA ( State Hazard Mitigation Plan, other Plans, and Guidance Grant Information Hazard Data and Information Maps, GIS Data, Analysis Tools (MyPlan/MyHazards) ABAG ( Hazard Mitigation Plan and Participating Jurisdictions Annexes Hazard Maps and Information Housing and Infrastructure Losses Data 29

30 Comprehensive & Collaborative SF Bay Area Coastal Study provides: Regional data set for understanding and communicating flood risk Input to the Hazard Mitigation Planning Process Foundation for coastal resilience planning Stepping stone for sea level rise vulnerability and risk assessments and adaptation planning 30
