Risk MAP lncreasmg Resilience together www.fema.gov/plan/preventjfhmjrm_main.shtm · 1- 877-FEMA MAP Open Pacific Coast Counties Following FEMA’s due process and statutory Risk Mapping, Assessment requirements, the new BFEs and hazard zones will be Phase 1 and Planning (Risk MAP) presented in revised Flood Insurance Study reports and Digital Flood Insurance Rate Maps. FEMA has identified FEMA is initiating flood studies and mapping projects nationwide federal, state, tribal, regional, and local stakeholders who in coastal areas as part of Risk MAP, a new FEMA program that will may contribute to, or be affected by, the Open Pacific provide communities with more accurate flood maps, risk assessment Coast study. FEMA will continue to coordinate with these tools and support for planning and outreach efforts that they can use stakeholders as the study and mapping efforts progress. to enhance their hazard mitigation plans and better inform and protect their citizens. These efforts will address gaps in required engineering and mapping for high flood risk areas impacted by coastal flooding, levee systems, and other flood hazards (e.g., lakes, rivers, and ponds). More Information Cumulatively, the coastal flood mapping projects in Region IX are being Visit www.r9coastal.org to learn more about the Open referred to as the California Coastal Analysis and Mapping Project Pacific Coast Study and to stay informed of the progress (CCAMP), of which this Open Pacific Coast study is a major component. of this project. FEMA welcomes your feedback, questions and comments. In addition, comments can be submitted on the “Contact Us” tab on the webpage. Open Pacific Coast Study Overview The Region IX office of the Federal Emergency Management Agency (FEMA) is in the process of performing a detailed coastal Phase 2 engineering study (modeling and analyses) of the Pacific coast of Coastal Mapping Timeline California. Results from this study will be used to remap the coastal flood risk and wave hazards for the California coast in two phases: northern California from Point Conception to the California-Oregon 2010 2011 2012 2013 2014 2015 2016 border, followed by southern California from Point Conception to the California-Mexico border. To date, FEMA has completed a review PHASE 1 Discovery/ (Planned) Kickoff Data Acquisition & Analysis and analysis of available data for use in these studies, excluding Meetings the San Francisco Bay area. Data gaps were determined during this Floodplain process and filled, as necessary. The coastal studies for both regions Mapping of the California coast are now underway and will be conducted in California Coastal Analysis accordance with FEMA’s February 2005 Pacific Guidelines for new Preliminary DFIRMs and Mapping Project coastal studies, which are included as part of the Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix .D As Post-Preliminary needed in future years, FEMA will continue to seek new data and Processing

updated modeling approaches that are best suited for Pacific Ocean Effective coastal studies. To learn more about the FEMA Open Pacific Coast Maps Study, please visit www.r9coastal.org. PHASE 2 Discovery/ FEMA’s coastal mapping efforts benefit from new technologies and (Approximate) Kickoff Data Acquisition & Analysis Meetings coastal data, including recent collection of detailed topographic data using Light Detection and Ranging (LiDAR). This new high resolution Floodplain Mapping digital elevation data will update topographic maps along the entire California coast. Two dimensional wave models will be used to Preliminary transform offshore waves to nearshore coastal waters. The results DFIRMs from these modeling efforts will provide boundary conditions for Post-Preliminary Processing detailed onshore coastal flood hazard analyses. Key coastal processes such as wave setup, wave runup and overtopping, and overland wave Effective propagation will be accounted for in determining new Base Flood Maps Elevations (BFEs). Dune and bluff erosion will also be considered

when mapping new coastal hazard zones. www.californiacoastline.org Project, Coastal Records California & Gabrielle Adelman, Kenneth © 2010-2011 Copyright Photo: Ongoing coordination and collaboration with Federal, State, Indian Tribal entities, regional and local stakeholders.
