Announcements GIS Services Upgraded at the Map Service Center

Series of improvements on the Map Service Center (MSC)

These upgrades include:

• National Flood Hazard Layer (NFHL) data is now searchable through Map Search

• NFHL databases are downloadable from MSC Product Catalog

• Effective DFIRM Databases have been replaced by the NFHL Databases, which are

available at no charge

• New NFHL Status Page for the latest updates, announcements, and links to data

• County/Community NFHL Databases are refreshed for updates on a daily basis,

ensuring that the public now has free, steady access to the most up-to-date flood

hazard data. Updated descriptions and documentation are also now available and will

serve as a resource to help users get the most out of the NFHL dataset.

If you have any questions or concerns, please contact the FEMA Map Information

eXchange (FMIX) at 1-877-FEMA-MAP

CFLA Concept

Create a dictionary of possible coastal flood conditions and losses to support pre- and post- hurricane landfall strategies

Unite Hazus loss analyses and FEMA Hurricane Program

SLOSH Storm Surge Modeling

Hurricane Evacuation Studies

Risk & Vulnerability Data & Analyses

Improve Hazus Coastal Flood Loss Model quality and capability

Assess potential program, public, and/or individual vulnerabilities, risks, and losses (Critical Facilities and Infrastructure, NFIP, IA/PA, RSDE, Repetitive Losses, etc.)

CFLA Hurricane Surges

Piggyback on the scientific storm surge modeling expertise of the National Hurricane Center for best hazard data

SLOSH (Sea Lake and Overland Surge from Hurricanes)

Basin updates paid for by FEMA Hurricane Program

Accurate, readily available, and independently validated

Maximum Envelope of Water (MEOW) provided by NHC approximately 36 hours prior to expected hurricane landfall

SLOSH Maximum of Maximums(MOMs) values for depth grid generation and analysis.*

Coverage for all U.S. coastlines vulnerable to hurricane surges

MOMs provide worst-case high water values at particular locations, and are used for hurricane evacuation planning (HES)

MOMs bookend MEOWs: All landfalling hurricanes will have surge values between one category lower and one category higher

Visualization of hurricane surge flooding

Risk/vulnerability analyses for the entire U.S. East Coast

Atlantic & Gulf Coasts – Texas to Maine

FEMA Regions I, II, III, IV, and VI

What you can get from the CFLA

107 SLOSH or Hazus-generated loss attribute values

No. of substantially damaged critical facilities

Shelter needs

Debris totals (Tons and Truck Loads)

Potential economic loss values

Per capita losses

Maximum water depth by category

*Based on NHC guidance, there are

no Category 5 MOM developed for

FEMA Regions I, II, or III (VA to ME).

Applications of CFLA

Hurricane surge scenario support for exercises

Future planning/response planning in RRCC/NRCC

Risk/vulnerability assessments for mitigation planning

Visualization of estimated overland flood inundation extents

Pre-storm assessment of vulnerable populations and infrastructure

QA/QC support for real-time hurricane landfall analyses by FEMA’s Modeling Task Force (MOTF)

Assessment of potential impacts to FEMA Programs

USAR, NFIP, Individual/Public Assistance, etc.

Example - Response Planning

Example – Visualization of Surges

An Alternative Approach toEvaluate Potential Risk –

Total Exposure in Floodplain(TEIF)

2

Need - Alternative Approach toEvaluate Potential Risk

FEMA Region III utilizes multiple parameters toprioritize Risk MAP communities for engagement.

• At risk population, existing relationships, level of potentialrisk

The Average Annualized Loss (AAL) study has beenused 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 evenwhen 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, andrequires an alternate approach

• Enhanced HAZUS for entire Region (or at least byStates?)

• Other lower-cost solutions, such as a “TEIF” analysis!

NoRisk?

3

New Approach - Total Exposure inFloodplain (TEIF) 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 HazardAreas (SFHAs).

• Use in lieu of the AAL study.

• Utilized for relative comparison for community engagement and actionpotential ranking.

5

Assumptions and Limitations

Building Counts are equally distributed.

0 Building Count, 0 Population Count for 2010 Census Blocks

0 Building Counts, Some Population Count for Census Blocks

Combination of Binomial Areal Interpolation and WeightedAreal Interpolation.

Use existing enhanced HAZUS analyses as “target” datapoints to compare AAL and TEIF Performance

6

TEIF 2.0

Proposed Pilot: Washington County, MD

Building Distribution• GIS Inventory

• LiDAR – based inventory

• Compare GIS and LiDAR outputs to determine validity of LiDARapproach

Dasymetric approach• Use best available LULC data

• Cleans up “noise” in data

7

Automated Building Extraction

Automated LiDARExtraction• Parameters for height above

ground

• Parameters for area

• Contingent on minimumspecifications from LiDARcollection

Density

Intensity

Return angle

• Applicable to multiple LiDARsoftware platforms

8

Benefits and Drawbacks to TEIF2.0

Drawbacks• Diminishing returns in accuracy after initial automated LiDAR pass

• Only one storm interval

Benefits• Better building distribution

• Less “noise”

• Potential low cost solution for estimating structures at risk

• Makes use of local data where available

9

Additional Applications of TEIF Onset of a Risk MAP project

• Inform engagement priorities – aid team in making more informed resourcedecisions

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 riskassessments through Risk MAP

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 insome project areas
