CO-OPS

Inundation

Network Danielle Nagele CO-OPS Risk Communication Specialist danielle.nagele@noaa.gov

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

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.

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.
