What is the user defined facilities approach?What is the user defined facilities approach?

User defined facilities are those structures, other than essential facilities or high potential loss facilities, which the user may wish to analyze on a site-specific basis.

You can construct a base model that will allow you to extract Hazus outputs on a site-by-site basis.

Hazus VersatilityHazus Versatility

Hazus has evolved into a multifaceted planning tool

Regionally relevant Hazus models can be used for:

Public information

To support benefit cost analyses for mitigation grant applications

Risk based analysis of capital projects

Risk Assessment

“What if” scenarios

Planning (mitigation, emergency management, COOP, debris management)

Public OutreachPublic Outreach

Hazus is a powerful public outreach tool

To gauge peoples perception of risk, you need to be able to show them how a hazard may impact them personally (“I never new !”)

A regionally relevant risk assessment is the key.

Can really promote the concept of mitigation

“Have you thought about……?”

People like having access to this type of information

Very media friendly!

Hazus and BCARHazus and BCAR

You want to apply for a mitigation grant for a flood hazard mitigation project.

You need to perform a BCA.

But, you don’t have historical loss data in the form of insurance claims or disaster records.

You don’t have a flood insurance study.

What can you do?

Hazus

Hazus and BCARHazus and BCAR

Hazus can be used to generate “expected” or “Historical” loss results that can be plugged in to the Damage Frequency module of BCAR

Keys

Must be a level 2,user defined module

Must be able to construct depth grids form creditable source ( H&H study, surveyed high water marks from historical events.

Recurrence intervals

Good data on inventory-(i.e. assessors data, elevation certificates, construction cost guides)

Risk Based Analysis of Capital ProjectsRisk Based Analysis of Capital Projects

Can use Hazus to perform “alternatives” analysis of capital projects.

Can compare losses avoided from one alternative to another.

“what if” scenarios

Can be a great tool to illustrate project benefits to garner political support.

Keys:

• Same as mentioned for BCAR support

Can use Hazus to perform “alternatives” analysis of capital projects.

Can compare losses avoided from one alternative to another.

Project Example-OutreachProject Example-Outreach Ada County, Idaho

30,000 user defined facilities were loaded into Hazus

Detailed structure information was extracted from County Assessor data.

Utilized LiDAR for depth grid production

Critical/essential facilities defined by the County were used in place of the Hazus defaults.

Set up Hazus work stations at public open houses.

Each citizen received a printout of property specific information relating to dam failure ,flood and earthquake.

Project Example-BCARProject Example-BCAR

Project Exodus-Tillamook Bay, OR FEMA 406 mitigation project

Over 500 used defined facilities.

Used pre and post project depth grids from H&H study (historic events).

Inventory was based on assessor’s data.

Replacement cost was updated using national cost estimation guides.

Loss results were validated

Hazus results were plugged into DFA module of BCAR.

Project ExampleRisk Based Analysis of Capital Projects

Project ExampleRisk Based Analysis of Capital Projects King County, WA

180th-200th Levee alternative analysis

Used Hazus and BCAR to look at impacts for 3 setback levee alignments, plus an existing condition analysis.

Hazus used to model pre and post project impacts.

BCAR used to calculate annualized avoided damages.

Analysis included levee breach probabilities.

Analyzed 4 flows, 3 dam operational scenarios, for 4 levee alignments (that is 48 sets of depth grids!)

Over 1900 user defined facilities

What we have found…..What we have found…..

The potential applications for Hazus at the local level are many.

The key’s are:

• Good data !

• Thorough understanding of the application’s within the model- (knowledge of its strengths and limitations).

• Ability to validate results

FEMA should acknowledge the versatility of Hazus in all of its programs.

Historic loss data is not always available. Then what?
