2. CCAMP / OPC Study ASFPM May 19, 2011 Agenda Risk MAP and Coastal Studies Open Coast Study Areas Process & Schedule of Studies Study Area & Guidelines Coastal Data and Resources Study Methods & Scope

3. Risk Mapping, Assessment and Planning (Risk MAP) Vision: To deliver quality data that increases public awareness and leads to action that reduces risk to life and property Address gaps in flood hazard data Ensure public awareness through outreach Lead and support hazard mitigation planning Provide an enhanced digital platform Align risk analysis programs FEMA will collaborate with federal, state, and local stakeholders to achieve the following goals under Risk MAP: Vision Goals ASFPM May 19, 2011

4. California Coastal Analysis and Mapping Project Open Pacific Coast Study A Risk MAP project with a coastal focus Re-study all California coastal counties along the open Pacific coastline. Re-map the coastal flood, wave hazard, and associated risks. CCAMP / OPC Study www.r9coastal.org ASFPM May 19, 2011
