Announcements FEMA Region III E172 HAZUS for Flood Training
This is not the same course offered in October 2013 - Focus on the State’s specific needs related to flood risk assessment.
The initial course provided the basics of HAZUS, however further training is necessary to accurately operate the HAZUS models. This course will train participants to completely operate the HAZUS flood model, understand the necessary data inputs, the quality of data inputs necessary, and how to interpret the results for decision making.
Intended for FEMA Region III Federal State, County, Local Gov. & University partners
4 day Course – Onsite session
Day 1-3: Official E172 HAZUS for Flood training course
Day 4 : Interactive session with dynamic discussion, highlighting the intersections between HAZUS and Mitigation Planning. We will discuss the State’s specific challenges related to flooding, analyzing that risk and informing mitigation strategies. We will discuss the State’s specific challenges related to flooding, analyzing that risk and informing mitigation strategies.

Tracking spatiotemporal patterns of
building vulnerabilities and
evacuations during flood hazards
Shane HubbardJunchuan Fan
Kathleen StewartEmily White
The University of Wisconsin – Madison, SSEC/CIMSSAugust 6th, 2014
Background
June 2008, Iowa City
Record flood by 3 feet (1993)
25 buildings damaged on the UIowa Campus
Flood damage and rebuilding costs $743M – $1B (2011 Globe Gazette) – contents in the $100Ms
Classes cancelled and major research programs were delayed or even lost
Arts Campus
A Unique Evacuation
Open Research Questions
Approached by University group responsible for flood planning and response.
What are the factors that affect campus evacuations?
Critical infrastructure?
Research?
Student Housing?
How to design a model that can be used to support decision-making about building evacuations on campus?
What are the underlying spatiotemporal properties of a model for campus building evacuations?
A foundation for evacuation planning
The model will
provide a means to analyze and visualize a time-varying flood
boundary and how it intersects with different parts of the campus
show which parts of the campus are vulnerable to flooding as the
flood boundary changes over time
form the basis for prioritizing evacuations on the UI campus
based on information about the spatiotemporal properties of the
flood boundary combined with data about building location,
contents and access
Data collection: flood boundary data
Obtained a set of flood depth grids for the Iowa River from The Iowa Flood Center
Our model begins with flood depth grids that equate a 17-foot (7,180 cfs) flood stage along the University of Iowa campus
The National Weather Service (NWS) reports the University of Iowa Campus sees building damage at approx 27 feet (25,100 cfs)
Flood depth grids continue every 0.5 feet of flood stage from 17 through34 feet (55,000 cfs)
Automation
The process of creating flood
layers and formatting each into
a GIS layer viewable on a
webpage.
Automation allows real-time
depth grid development on the
fly
Coffer dam
Sandbagging efforts
Data collection: spatial data
Acquired spatial data from Facilities
Management
Updated GIS data of all campus
roads, buildings and residence
halls, sidewalks, parking lots, and
steam tunnels as provided by
Facilities Management
Statewide LiDAR data
Elevation data for campus
terrain, campus buildings, river
Campus-wide orthophotos collected
June 15th, 2008 for validation
University of Iowa FERP
The University of Iowa has a detailed FERP that has been updated
to July 2009 and more recently in 2012
Details critical buildings – building watch list
Evacuation plans
The FERP identifies 30 buildings as at-risk facilities potentially
within the flooding boundary
As part of our research, we have revealed a further seven facilities
also inside the flood boundary

Building the evacuation model
Two step process:
A spatiotemporal analysis between flood boundaries and depth gridswith University of Iowa infrastructure have been computed to determine campus areas at risk for flooding
i.e., the buildings, roads, parking lots, etc.
Based on these intersections and building elevations, we can determine what features are vulnerable with each new change in flood stage
Time is being incorporated in the model so each flood stage and associated depth grid is associated with a likely time of building inundation.
Evacuation start time =
Time of risk** – Time needed to evacuate building contents
Building Risk Layers
Flood depth grids were translated into flood elevations
Flooded buildings were identified for each flood elevation and
placed into categories
Vulnerable basement (0.5 ft grid before flooded basement)
Flooded basement (revised with 2008 Flood data)
Vulnerable first floor (0.5 ft grid before flooded basement)
Flooded first floor (flood elevation and first floor elevation)
Vulnerabilities are calculated to account for uncertainty
Data collection and preparation
Basement flooding analysis
Using data from the FERP, fields for the elevations of basements, and sub-basements of buildings on the watch-list were added to the GIS layer of university buildings
For buildings with multiple basement elevations, there is a record for each of the basement elevations
The estimated water table depth, the level of water in the basement, and the distance from the building to the nearest flooded area, were recorded for each flood depth
But during validation found this did not produce accurate results…
Used the data collected from interviews on when the basements flooded and what the corresponding flood elevation was at the time.
Data collection and preparation
First-floor flooding analysis
Data from the FERP provided first-floor building elevations. The building data layer was intersected with the flood depth elevation rasters.
When such an intersection exists, the flood elevation depth is compared to the first floor elevation for the building
If the first floor elevation is less than the flood elevation, the first floor is considered flooded
A zonal statistic is used to calculate minimum, maximum and mean water levels on the first floor. Max was used.
Building Risk Layers
Building risk is tied to a specific
flood level.
In real-time risk layers are
displayed based on the current
and forecasted flood level
Risk Analysis Results

regulations
Hazus-MH Depth/Damage Analysis
The possible damage severity to each building was tracked using
the average flood depth from a zonal statistics analysis in ArcGIS
and then assigned a damage% from the damage curves in Hazus-
MH.
There are major differences in the damage functions and the default
value does not reflect the historical depth damage relationship on
the campus.
Building content information
The direct flood risk to the building is not the entire problem….
During the summer, we interviewed representatives from each of the 30+ buildings on the watch-list
We collected data on
estimated time needed for evacuation today
time needed for evacuation during 2008 flooding
details on where contents need to be moved
challenges encountered during 2008 flooding
length of time building was closed due to flooding
key contents that would need to be evacuated
details on numbers of building residents, vehicles, etc.
Diversity of vulnerable buildings
The vulnerable buildings represent a very diverse set of needs and
times for evacuation
For example
The University Library
Mossman Business Services Building (campus mail…)
UIHC Patient Transportation Services
South Gilbert Street Building (Hawkshop, bookstore storage)
Lindquist Center – UITV, ITS
Power Plant, Water Plant, IMU…
Interview Findings
Certain research projects can be extremely sensitive to evacuations
Million dollar projects cannot be moved overnight
Residence Halls are difficult to evacuate
If summer, key faculty or administrators who would normally lead an
evacuation may be away (what do we take?)
Time available for evacuation is important…2 days? 5 days?
What is the maximum time available for evacuations?
Road and Bridge Closures
An important variable for modeling building evacuations is road/bridge closure or access to a building.
Evacuations are road closure dependent
Road and bridge closures are computed for each flood elevation
Produces 2 additional evacuations.
Evacuation Time
The recommended time evacuate is calculated by…
The time estimated to evacuate the building (determined by building
interviews)
The expected time of arrival of flooding or the loss of building
access from inundated roads or closed bridges.
Subtract the necessary time to evacuate the building from the
expected time of arrival of flooding
Conservative estimate…expected time of arrival of flooding is based
upon the vulnerable basement inundation time.
Evacuation Layers
Restoration Time and Priority
An important consideration for evacuation priority is the length of time required to make the building functional again.
Zonal statistics were used in ArcGIS to calculate the average flood depth.
The Hazus-MH restoration functions were modified to estimate the time for building restoration
University administrators may elect
to change the evacuation
recommendation time based-
upon the level of importance of
the building vs the time to
restoration
Spatiotemporal Evacuation Model
We have developed a real-time, visual, interactive model that uses a map-based interface to allow users to interact and query the spatiotemporal characteristics of a flood event and plan for possible evacuations
Google Maps API to present the model in a web-based platform.
Connected to a SQL database for data storage.
Putting everything together
Interactive model is based on
Our modeled assessments of
infrastructure at risk

2008 Iowa City Flood Results
There is a spatiotemporal progression of flood evacuation start times across the University of Iowa campus.
Not related to any flood surge movement downstream.
Essential in understanding this pattern during real-time evacuations for congestion around evacuated buildings.
Differences for every flood.
User Interaction
Flood officials at the University requested a means for identifying what actually happens versus what we suggest should happen.
Form was designed to provide the user with designating the current evacuation status for each vulnerable building
Flash flooding
University decision
An additional layer is also present in the application.
Temporary Mitigation on Campus
Future floods on campus will be mitigated with the use of HESCO barriers.
The Iowa Flood Center used a HESCO layer to simulate the changes to the floodplain as a result of the mitigation measures.
At this time evacuation recommendations are only calculated on the NO mitigation layers.
….And model validation
Future Work
Extend model to capture recovery times
The depth of water predicted inside the
building.
Important for faculty, staff, and students.
Enhanced evacuation times based on…
Floor area that will be evacuated.

Modernization Phase 1: Project Tasks (Tues Aug 5th)
Task 1: Upgrade Hazus to be compatible with ArcGIS 10.2 and Windows 8 = Hazus2.2 first major release in 2.5 years
Task 2: Functional enhancements to the Flood module (inventory and SP release)
•Apply the dasymetric GBS exposure distribution approach
•Synchronization of depth damage functions
•Implement study region aggregation at custom jurisdiction or neighborhoodlevels
Modernization Phase 1: Project Tasks (Wed Aug 6th)
Task 3: Re-architecture and source code update
•Replace MS Access (.mdb) personal Geo-Databases (pGDB) for all modules
•Migration of DTS packages to SQL Server Integration Services (SSIS)
•Replace VB6 and COM architecture with .NET (C#) for flood module
Task 4: Develop Proof of Concepts
•Feasibility of NFHL data integration with Hazus Level 1 hazard determination for 1% and0.2% flood risk
•Performing building and economic AAL using a combination of NFHL and Hazus floodreturn periods
Modernization Vision:
Improved Accuracy: Enhanced site-specific capability. Enhance Level 1 losses improving block level losses by implementing dasymetric methodology
Hazus-lite Capabilities: Provide Hazus capabilities to a larger non-technical audience through a web-based interface.
Modernization Vision:
Web-Enabling: Many good examples (NC FRIS, ImageCat Inlet, RMS One, etc.)
Leverage FEMA GeoPlatform capabilities:
Viewer and reporting
Data archiving and access
Development and application environment
Upcoming Functional Enhancements:
1. Alignment of the Benefit Cost Analysis (BCA) andHazus-MH Flood Model Coastal depth-damagefunctions
2. Study region aggregation by CID community
3. Dasymetric general building stock exposuredistribution approach based on national land coverdata
Better Alignment with FIMA:
Better integrate NFIP and Risk MAP data directly with Hazus.
The Risk MAP National Flood Hazard Layer would be pulled directly intoHazus.
Incorporate NFIP approaches and rating methods
Provide reports integrated with NFIP impacts.
Improved reporting would be introduced to more directly feed hazardmitigation plans and better support benefit-cost analysis (BCAs).
Hazus MH BCAR Alignment (Task 2-Functional Enhancements)
Incorporate New Expert Panel Coastal A and V Zone Depth DamageFunctions (DDFs)

1. Benefit Cost Analysis (BCA) Alignment for Damage Functions
Hazus currently provides an extensive Depth Damage Function (DDF) librarythat was initially used for the BCA tools modernization effort several yearsago.
Our BCA program within the Mitigation Directorate at FEMA is criticallyimportant in ensuring that our mitigation investments and sound and costeffective.
This task will incorporate the latest additional DDFs from the BCA programrecently developed for coastal flooding.
This task enhances our alignment with FIMA programs and ensures Hazusloss projections can align with BCA benefit assessments.
Community Based Analysis (Task 2-Functional Enhancements)
Build and analyze study regions based on CID (Community Information Data)
What is CID?
•Based on 2010 Census jurisdiction boundaries
•Linked to NFIP’s Community Information System (CIS) that tracks community map adoption and participation
•Now incorporates tribes
•Aligns with other FEMA programs (NFIP, Mitigation Plan tracking)
