GIS Valuable Tool in EM

Identify risk

Identify vulnerability to that risk

Assess the extent of the risk

Communicate the risk

Better land use decisions

Prepare for

Respond to

Recovery from

Mitigate (before, during or after an event)

Presenter

Presentation Notes

If we identify the risk such as floodplains, Identify what is vulnerable such as critical facilities, schools, hospitals, haz mat sites, special populations, etc. And assess how high the risk is then we can begin to effectively communicate that risk to the public. In addition, knowing the risk we can make better land use decisions such as preventing development in floodplains, etc. By identifying the risks and what is at risk, will enable those involved in emergency management to develop plans based on that risk which will facilitate a better response when an event does happen and speed up recovery. In addition, if we know where and what is at risk, we can begin to mitigate those risks such as removing people from floodplains.

Response/Recovery -

Damage Assessment

Presenter

Presentation Notes

Stoughton tornado in August 2005. Using images from the Environmental Remote Sensing Center you could clearly see the path of damage. Then based on the path, datasets from Dane County were used to determine the parcels damaged. Along with assessment information can determine the amount of damages.

HAZUS (HAZards US –

Multi-Hazard)

Federal Emergency Management Agency (FEMA) disaster loss estimation and mitigation planning tool

Geographic Information System (GIS) based

Spatial Analysis tool required

Expensive to purchase and to maintain the licenses

Census Data

Methodology for Floods, Hurricanes, and Earthquakes

Physical damage

Economic Loss

Social Impacts

HAZUS -

Flood

Studies of discharge frequencies, including analysis of discharges from specific streams and the exposure to buildings and population from the resultant flooding.

Allows users to evaluate the consequences of specific actions, such as the introduction of flow regulation devices, acquisition or elevation of flood-prone properties, and other mitigation measures.

Wisconsin HAZUS-MH Risk Assessment

FFY 07 Pre-Disaster Mitigation Grant

Coordination with Land Information and Computer Graphics Facility (LICGF) at UW – Madison and The Polis Center at Indiana University – Purdue University at Indianapolis (IUPUI)

State wide riverine runs for all 72 counties and coastal runs for counties along Lake Superior and Lake Michigan

Uses Digital Elevation Maps (DEM)

DFIRMs where available

Better the data, better the ending product

Darker blue is deeper flood depths.

Mitigation Planning

Statewide flood hazard risk assessment for State Hazard Mitigation Plan

Flood analysis for each county

Assist in the development of or updating the counties’ all hazard mitigation plans

Project Monitoring and Compliance

Presenter

Presentation Notes

Since the 1993 we have been providing mitigation grants to communities to acquire and demolish floodplain structures. The land is deed restricted for open space uses. 3-year monitoring requirement. Kenosha County has been implementing a buyout program since the mid-90’s. This is in the Town of Wheatland on the Fox River taken in 1995.

Presenter

Presentation Notes

Taken in 2008. Clearly can see the structures that have been removed. Have a database of parcels. Along with that information and the aerial photography, we can see where there might be violations of the deed restrictions. But also demonstrates our successes.

GIS in Radiological Emergency

Planning

GIS in Radiological Emergency Preparedness

Currently, only FEMA Region 5 has a GIS person devoted to Radiological Emergency Preparedness.

GIS in Radiological Emergency Preparedness

Only in the last 3 years has Wisconsin Emergency Management considered GIS as part of the skill set for employees.

4 staff with GIS skills

Uses of GIS in Radiological Emergency Management

Communicate Risk

Develop Plans to mitigate risk

Recovery – Post Event

Communicating Risk

GIS can be a powerful tool in the process of conveying risk.

Community Outreach

Planning Zones

Calendar

GIS in Risk Assessment and Planning

Provide the public with maps that show:

Areas that may be affected around the nuclear plant.

Roads

Evacuation Routes

A calendar is sent to each resident within 10 miles of the nuclear power plant.

State and County Plans

Reception Centers

Siren Locations

Traffic Control Access Points

Use of GIS in Exercises

To provide a visual aid in conveying technical data about a release.

Exercise Use Only

Parcels

Ingestion workshop

Ingestion Planning Zone extends 50 miles from the nuclear plant.

Discussions included using land parcels as a means to track individuals who did not evaluate.

Recovery

Why… There has not been an accident since Three Mile Island that has caused an evacuation.

Lessons could be taken from other incidents that require recovery, such as flooding.
