San Francisco Bay AreaCoastal StudyInaugural Bay Area FMA LuncheonMarch 13, 2013

California Coastal Analysis andMapping ProjectTwo Companion Large-Scale Efforts:• San Francisco Bay Area Coastal Study• Open Pacific Coast StudyRe-study flood riskalong the open coastand inland bays of allCalifornia coastalcountiesRe-map the elevationand inland extent ofwave-induced coastalfloodingwww.r9coastal.org2

Risk MAPVisionTo deliver quality data thatincreases public awarenessand leads to action thatreduces risk to life andpropertyObjective (Coastal)To provide updated flood hazarddata for 100% of the populated U.S.coast3

Comprehensive & Collaborative• Covers 100% of the SanFrancisco Bay coastalcommunities in 9 counties• Leverages latest 2010 NOAAand USGS LiDARtopographic data• Regional hydrodynamic,storm surge, and wavemodeling• Detailed onshore coastalhazard analysis• Outreach, coordination and collaboration with numerouspartners, stakeholders, and other studies4

Overland Coastal Hazard Analyses• Transect-based analysis• Wave runup• Wave overtopping• Wave propagation overland• Transect locations anddensity based on:• Shoreline type andcharacteristics• Shoreline direction• Nearshore bathymetry• Wave dynamics• Land use and development11

Floodplain Mapping (Work Maps)12

Flood Risk ReviewMeeting

Flood Risk Review Meeting• Provide an overview of the National Flood InsuranceProgram (NFIP) and Risk MAP• Provide an overview of the San Francisco Bay AreaCoastal Study• Discuss coastal study process and methodology• Review and discuss the draft Work Maps and theonline tool for review and comments• Discuss how the products can inform decisions toreduce flood risk• Learn how to communicate about flood risk usingthe products and datasets• Answer questions14

On-line Work Map Review Tool15

Tool Overview• Post draft Work Maps online at r9coastal.org forcommunity review• Accommodate community staff need to review databeyond the meeting timeframe• Reduce paper mapproducts from theworkflow – andreduce the potentialfor lost comments16

Comment Process• Users will be provided a unique login and password• Communities will have 30 days to review the WworkMaps• All comments will berecorded andarchived• Comments will betaken intoconsideration as themapping entersproduction17

Flood Risk Awareness Surveys• Nationwide, Research-based• FEMA surveyed local officials in 2010 to:• Provide a baseline of flood riskawareness• Inform national outreach andcommunity engagement activities• FEMA conducted a second survey in 2011 to trackprogress toward its awareness goals:• Public awareness and understanding of risk management• Local official awareness of flood risk within Risk MAP projectareas23

Survey Says…• The following tools would make it easier for localofficials to share flood risk information with thepublic:• Information to add to community websites• Publications for building owners on reducing risk• Customizable letters or brochures• Media materials such as draft press releases24

Tools, Templates and Products• Tools & Resources –• FEMA website - library• www.r9coastal.org• Mapping, LOMC guidancedocs, flood insurance,floodplain management• 1-877-FEMA-MAP• Study Brochures• Coastal Beat• Templates –• Community Outreach PlanTemplate• Press release• Open House Materials• Non-regulatory Products –• Changes Since Last FIRM25

Hazard Mitigation Planning• What is Hazard Mitigation?• Any sustained action taken to reduce or eliminate longtermrisk to human life and property from hazards• Why are Hazard Mitigation Plans Important?• Foundation for a long-term strategy to reduce disasterlosses and break the cycle of disaster damage,reconstruction, and repeat damage• Provides a framework for risk-based decision makinginvolving stakeholders and the public.26

Hazard Mitigation Planning• How is Hazard Mitigation Planning relevant to SF BACStudy?• Results of the Study (FIRMs) enable communities to “IdentifyRisk,” the first step in the Risk MAP Life Cycle• Mitigation Planning provides the framework to carry out theremaining 3 steps in the Risk MAP Life Cycle using Studyresults• Assess Risk and Vulnerability using Coastal Flood HazardInformation/Data• Communicate Risk through public involvement – increaseseducation and awareness of Hazards and Risks• Mitigate Risks by identifying actions and aligning them withother community objectives27

Hazard Mitigation Planning –Resources• FEMA (http://www.fema.gov/multi-hazard-mitigation-planning)• Laws, Regulations, Guidance, Policies• How-To Guides• Mitigation Grant Funding Programs• Training• Cal EMA (http://hazardmitigation.calema.ca.gov/)• State Hazard Mitigation Plan, other Plans, andGuidance• Grant Information• Hazard Data and Information• Maps, GIS Data, Analysis Tools(MyPlan/MyHazards)• ABAG (http://quake.abag.ca.gov/resilience/)• 2010 Hazard Mitigation Plan and ParticipatingJurisdictions’ Annexes• Hazard Maps and Information• Housing and Infrastructure Losses Data29
