Risk MAP (Mapping, Assessment, and Planning) Vision
Vision Statement
With State, Local, Tribal, Non-Profit and Private-Sector collaboration, Risk MAP delivers
quality data
that increases
public awareness
and leads to
action that reduces risk
to life and property
Goals 1.
Address gaps in flood hazard data
2.
3.
Increase risk awareness to encourage risk reduction Risk-based MT Planning resulting in risk reduction actions 4.
5.
Enhanced digital platform to improve communication and sharing of risk data Align programs and develop synergies 3
Risk MAP Coastal Studies Goal
Risk MAP Goals (from Risk MAP Multi-Year Plan (2010-2014) (FEMA, 2009))
Goal 1: Address gaps in flood hazard data to form a solid foundation for flood risk assessments, floodplain management, and actuarial soundness of the National Flood Insurance Program
• Initiate Risk MAP flood map update projects to address gaps in required engineering and mapping for high flood risk areas impacted by coastal flooding, levees, and other flood hazards (e.g. lakes, rivers, ponds) FEMA and Congress have identified coastal flood hazard updates as a priority Provide updated or validated flood hazard data for
100 percent
of the
populated
coastal areas in the Nation.
Requires coastal funding through FY 2013 to initiate all updates
Studies identified and prioritized by Regional Offices with knowledge of mapping needs, flood risk, cost-share, and other factors

Why Focus on Coastal Flood Risk?
120,475,000 people or 39% of the U.S. population live in counties subject to the 1% annual chance coastal flood, and/or border the ocean or Great Lakes coast.
~ 8,622,000 people (3% of the total U.S. population) live in coastal areas subject to the 1% annual chance flood
• Includes only permanent residents. Additional seasonal residents add to the number of people at risk • Larger storms will affect more people
Coastal Population > 1% risk

Risk MAP Coastal Studies – Schedules and Costs
Schedule
• Avg. time to coastal prelim = 4 years • Avg. time to riverine prelim = 2 years Year 1 Year 2
Costs
• Avg. cost per coastal mile are higher than avg. cost per riverine mile.

Projected Preliminary Dates

Upcoming Preliminaries
Projected for 2012
•
Texas Coast
• • • • Eastern Panhandle of FL Delaware Massachusetts A few counties here and there in LA, MD, WA, and RI
Projected for 2013
• • Large portions of the Mid-Atlantic Some additional areas along the Gulf of Mexico and New England • Some Pacific Coast counties in CA, OR, and WA
Notable out-year projections
• Majority of FL: 2014 – 2017 • Great Lakes: 2014 – 2016 10

Coastal Non-Regulatory Products
When are non-reg products produced?
• Operating Guidance for the Selection of Enhanced Datasets • Availability of coastal analysis modeling information • Will the information be beneficial to the communities?
Increase risk awareness?
Facilitate mitigation actions?
Products may be produced for the entire coastline or focused areas determined to be the most valuable
• Discovery process should facilitate these selections
Additions to Flood Risk Map, Flood Risk Database, & Flood Risk Report
Datasets will not be recreated from existing data available outside of FEMA. Direction to such information will be provided in the Flood Risk Report

Coastal Non-Regulatory Products
Concept: Better leverage FIS data to convey information about coastal hazards to enhance risk awareness and encourage action at the community-level to reduce those risks Standard products:
•
Changes Since Last FIRM
•
1% Annual Chance Flood Depth Grid
•
Risk / Loss Assessments
•
Areas of Mitigation Interest Coastal-Specific Products:
• • •
