CO-OPS
Inundation
Network Danielle Nagele CO-OPS Risk Communication Specialist [email protected]
FEMA HUG Meeting
Project Objectives
Provide support to local WFO, emergency managers, and broadcast media
Enhance visualization of water level information using socially relevant landmarks
Ultimately, assist local partners in their utilization and communication of inundation events
What is the network?
Familiar community locations
referenced to a single point
Socially relevant to the
community: statues, historic
sites
Important to planning process
of local EMs and government:
metro station, fire station
What’s the need?
Communication around storm surge and inundation events
Less confusion around referencing water height
More meaningful than 2 ft. above MHHW
Can describe water level to the public in the context of places they know
Frame of reference for historical events
Ex. Flooding during Superstorm Sandy reached to the waist of ‘X’ statue
New York Prototype
Benchmark installed at seawall in Battery Park
Network of landmarks throughout lower Manhattan chosen and surveyed
Engagement with local partners planned for early next year
‘Unveiling’ around hurricane season – possibly
coinciding with Sandy anniversary
Future Expansion Expanding to 2 or 3 new communities in
FY15
Norfolk, Annapolis – ‘top inundation’ areas
Integration and consideration of the local
community
Discussion with local partners on landmark
locations
Iterative feedback on design of new
platform or integration into existing platform
Potential Process
Engage local partners
• Needs assessment
Choose landmark locations
• Feedback
• Technical considerations
Platform/User-interface
• Iterative feedback
• Potential integration with existing tools
Continually consideration of potential partnerships in
each area – USGS, FEMA,
Sea Grant extension agents

Updated Total Exposure in Floodplain (TEIF) Method –
Washington County, MD Pilot
17
Need - Alternative Approach to Evaluate Potential Risk
FEMA Region III utilizes multiple parameters to
prioritize Risk MAP communities for engagement.
• At risk population, existing relationships, level of potential
risk
The Average Annualized Loss (AAL) study has been
used to identify and compare at risk communities.
• LIMITATIONS: Based on the 2000 Census, County-
wide study regions, and utilized course 30 meter DEM •
CHALLENGE - The AAL underestimates losses even
when used for relative comparison
• Especially in coastal communities.
• Ex. Bethany Beach, DE (Sussex Co) –
AAL reports NO coastal flood losses
THEREFORE the AAL does not meet our needs, and
requires an alternate approach
• Enhanced HAZUS for entire Region (or at least by
States?)
• Other lower-cost solutions, such as a “TEIF” analysis!
No
Risk?
18
New Approach - Total Exposure in Floodplain (TEIF) version 1.0
FEMA Region IV released 2010 Census
and ACS data integrated into HAZUS
• Updated to census tracts, applying 2012 RS
Means valuations.
• Includes update to the 2010 nationwide total
exposure data.
Development of Total Exposure in
Floodplain (TEIF) -
• Create a dataset using Arc GIS and MS
Excel.
• Determine an approximate value of Total
Exposure in Special Flood Hazard Areas
(SFHAs).
• Use in lieu of the AAL study.
• Utilized for relative comparison for community
engagement and action potential ranking.
19
GIS Solution – A Three Step Process Step 1
• Transfer 2000 Census Tract Total Exposure Dollar Values (Updated by
Region IV) to 2010 Census Blocks.
• 2010 Census Building Counts were used to distribute the 2000 Census Tract Dollar
amount to the 2010 Census Block units through binomial areal interpolation.
Step 2
• Assemble a statewide SFHA layer.
• Effective DFIRMs in the NFHL, Current Draft Preliminary DFIRMs, Preliminary
DFIRMs, DFIRMs at LFD, or newly effective DFIRMs
Step 3
• Intersect the 2010 Census Block Geography with Total Exposure Dollar
values and the statewide SFHA
• Areal Interpolation of 2010 Census Block in SFHA resulted in the ultimate TEIF value
20
Additional Applications of TEIF Onset of a Risk MAP project
• Inform engagement priorities – aid team in making more informed resource
decisions
Identify highest risk communities
Generally, more “accurate” risk assessment than AAL from perspective of relative risk
(i.e., this community has more risk or “exposure” than others)
Marketing tool
• Illustrate to communities the value of developing enhanced HAZUS risk
assessments through Risk MAP
Used to Prioritize CAV (Community Assistance Visits) meeting
schedule for FEMA Staff.
Supplement AAL with TEIF
• Non-regulatory HAZUS Risk Assessment product development
Another risk assessment tool for communities to consider
May help inform project scope needs by identifying need for enhanced HAZUS analyses in
some project areas
21
Next Steps (From September 2013)
Update all Region III community engagement plans with TEIF data
• Replace AAL component of prioritization with TEIF
Keep AAL-based analysis “on the side” for consideration and use where appropriate
• Evaluate all Risk MAP project community engagement plans and revise, where
appropriate
Generally, will not “reduce” engagement status of any community BUT may increase
engagement status of communities shown to have increased engagement needs
Eliminate exposure estimates in census blocks which are undeveloped
or natural areas based on Land Use Land Cover (LULC)
• Include in a Pilot Project for Washington County, MD for TEIF 2.0
Continue to validate approach and look for alternate uses
Include Building Footprint data (existing and extracted from LiDAR) in TEIF 2.0
Pilot.
Continue to improve TEIF approach and data over time
Should be cost effective to conduct annual updates as new flood data are
available, enhanced approaches are considered, etc.
22
Updated Approach - Total Exposure in Floodplain (TEIF) version 2.0 FEMA Region IV released 2010 Census
and ACS data integrated into HAZUS
• Updated to census tracts, applying 2012 RS
Means valuations.
• Includes update to the 2010 nationwide total
exposure data.
Development of Total Exposure in
Floodplain (TEIF) version 2.0 -
• Create a dataset using Arc GIS.
• Determine an approximate value of Total
Exposure in Special Flood Hazard Areas
(SFHAs).
• Use Building Counts from LiDAR extracted
buildings footprints.
• Apply Dasymetric approach to eliminate loss
estimates being applied to undeveloped
areas within Census Blocks.

Aerial Photography (2 – D)
provides a visual
interpretation of on the
ground features.
LiDAR Data ( 3 – D) provides
the ability to automate feature
extraction of planar surfaces.
24
Automated and Manual Process using TerraScan Software and ArcGIS
Automated – Part 1 • TerraScan Software (runs on MicroStation)
Building Classification Tool
Input needed: Point rich LiDAR file (.las) file
with ground classified.
• Produces rough polygon shapes through
export to ArcGIS. Automated process can
clean up rough outlines.
Manual – Part 2 • Automated process is not fool proof.
It’s incredibly cost efficient, but not
100 % accurate.
• There will be omission (missing
footprints) and commission (footprints
where no building exists) errors.
• Manual clean up involves spending
time with an aerial photo and intensity
imagery derived from the LiDAR data.

TEIF 2.0 GIS Solution – A Three Step Process Step 1
• Transfer 2000 Census Tract Total Exposure Dollar Values (Updated by
Region IV) to 2010 Census Blocks.
• Building Counts based on LiDAR derived Building Footprints and County Building
Footprint layer aggregated to 2010 Census Block data were used to distribute the
2000 Census Tract Dollar amount to the 2010 Census Block units through binomial
areal interpolation.
Step 2
• Assemble a statewide SFHA layer.
• Effective DFIRMs in the NFHL, Current Draft Preliminary DFIRMs, Preliminary
DFIRMs, DFIRMs at LFD, or newly effective DFIRMs
Step 3
• Intersect the 2010 Census Block Geography minus undeveloped areas
with Total Exposure Dollar values and the statewide SFHA
• Areal Interpolation of 2010 Census Block in SFHA resulted in the ultimate TEIF value
30
Step 1 - Transfer 2000 Census Tract Total Exposure Dollar Values (Updated by Region IV) to 2010 Census Blocks.
