Risk MAP Flood Risk Products
Flood Risk Products
• Flood Risk Report – Summary of local flood risk
• Flood Risk Map – Utilizes Flood Risk Assessment to visually depict flood risk
• Flood Risk Database – Raw data and results from flood risk assessment
Flood Risk Datasets
• Flood Risk Assessment – HAZUS loss estimation, identifies location
• Enhanced Coastal Depth Grids – Illustrate depth and velocity of flooding

HAZUS Loss Estimation
Using Changes Since Last FIRM
for Identifying Actions
Changes Since Last FIRM
 Communities and homeowners
can use this to identify the
impacts of new maps on the
regulatory Special Flood Hazard
Area (SFHA)
 Also reveals new areas that may
need mitigation actions – either
for existing assets or for future
planning
4
Using Depth and Analysis Grids for
Identifying Mitigation Actions
Baltimore Harbor
Under 2ft - 3ft
of water
 Better information on depth and velocity of
flooding
 More information on higher probability (10 &
25 year) flood events
 These provide enhanced data to develop a
more accurate Benefit Cost Analysis (BCA)
for mitigation projects, a big step towards
implementation
5
Using Flood Risk Assessment
for Identifying Mitigation Actions
Total Economic Loss – in $1000
$0 - $45,000
Baltimore Harbor
$45,000 – $220,000
$220,000 – $540,000
$540,000 - $4,100,000
 Identifies areas of higher flood risk
 Quantifies potential future flood losses to
existing structures
 Identify areas requiring higher building code
requirements
 Supports mitigation plan updates and
disaster recovery planning

Flood Risk Assessment:
ALL Coastal Communities will
receive an enhanced HAZUS
Risk Assessment
Where is the data?
 FEMA Map Service Center –
http://msc.fema.gov/portal
• The official public source for flood hazard information produced in support of the
National Flood Insurance Program ( NFIP).
• Includes DFIRM Database + Risk MAP Flood Risk Products
 Maryland Flood Map Status –
https://www.rampp-team.com/md.htm
• Includes upcoming meeting dates + milestone dates
• Access to training, LOMR status + fact sheets
 Maryland DFIRM Outreach
http://www.mdfloodmaps.net/
• Designed to guide homeowners/renters as well as communities through the
process of determining their current flood risk as well as future flood risk based on
the preliminary Digital Flood Insurance Rate Maps (DFIRMs).
10
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.
CLEAR Risk!
 Development of Total Exposure in
Floodplain (TEIF) • Create a dataset using Arc GIS and MS
Excel.
• Determine an approximate value of Total
Exposure in the SFHAs. (Effective &
Preliminary Maps – from May 2013)
TEIF - Value in $
0 - 3,000
• Use in lieu of the AAL study.
3,000 - 10,000
• Utilized for relative comparison for
10,000 - 30,000
community engagement and action
potential ranking.
30,000 - 70,000
70,000 - 140,000
11
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

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.

Extracting Building Footprints from
LiDAR Data planar surface recognition
Source: PAMAP
Aerial Photography (2 – D)
provides a visual
interpretation of on the
ground features.
Source: Google StreetView
Source: PAMAP
LiDAR Data ( 3 – D) provides
the ability to automate feature
extraction of planar surfaces.
15
Automated and Manual Process using
TerraScan Software and ArcGIS
 Automated – Part 1
 Manual – Part 2
• TerraScan Software (runs on MicroStation)
 Building Classification Tool
 Input needed: Point rich LiDAR file (.las) file
with ground classified.
• 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.
• Produces rough polygon shapes through
export to ArcGIS. Automated process can
clean up rough outlines.
Rough
Realistic
16
Dasymetric Approach to eliminate loss
estimates in undeveloped areas
 Follow Dasymetric Methodology for Hazus Functional Enhancements
for General Building Stock exposure distribution
• Dasymetric Methodology = Intersect National Land Cover Dataset (NLCD 2011) -
TIGER polygons to filter out non-built-up areas
• Only difference was to
use a 2010 10 M
Resolution Maryland
Land Use – Land
Cover Dataset.
• Matched Maryland
Land Use Codes with
the NLCD codes for
consistency.
17
TEIF in Maryland
 TEIF 1.0 is available for all counties in MD
• Enhanced HAZUS Delivered in Coastal footprint
 TEIF 2.0 is available in Risk MAP Riverine Projects
• Implementation priorities
 Counties with high resolution topo
data – Preferably LiDAR, OR
 Counties with a building shapefile
• Priority given to areas with..
 High risk to flooding
 Increasing population in the SFHA
 Deficient geospatial data
 Building replacement value, Age, Total built area, FFE,
Occupancy type (land use)

Broad Agency Announcement
Status and Plans

First year was an opportunity to “learn by doing” and we
have adopted proposer feedback into what is needed to
improve BAA process.

Major areas for planned development


Coordination – current thinking is to hold open 3DEP
coordination meetings 1-2 times each year in each state or region

Annual and multi-year plans – make Federal, state and other
plans and areas of interest available online, as the “planned”
companion to the “available” status of the inventory
Current BAA – never closes, major activity for FY 15
complete. FY 16 BAA announcement scheduled for July
