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.
Increase risk awareness to encourage risk reduction
3.
Risk-based MT Planning resulting in risk reduction actions
4.
Enhanced digital platform to improve communication and sharing of
risk data
5.
Align programs and develop synergies

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.
Coastal Population
> 1% risk
 ~ 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

 FY10
• $45.0M
 FY11
• $45.0M
 FY12
• $45.0M
 FY13 (Anticipated)
• $45.0M

Risk MAP Coastal Studies –
Schedules and Costs
 Costs
 Schedule
• Avg. cost per coastal mile are higher
than avg. cost per riverine mile.
•
Avg. time to coastal prelim = 4 years
• Avg. time to riverine prelim = 2 years
Year 1
Year 2
Year 3

Year 4
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

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
