Structural Zone Mapping

Structural Zone Mapping

• Its Use In All-Risk Incidents and for Evacuation
  Purposes
• Ralph Sheffer
• Fire Operations Specialist
• WI DNR
• 608-635-8101
• ralph.sheffer_at_wisconsin.gov

2
Zone Mapping What is it?

• Takes mapping of structural locations and breaks
  them into manageable units (Zones).

3
GIS mapping created and maintained from County
Land Information database
4

• Kept in 3 Forms
• Book in every emergency vehicle (extras for
  ICP/EOC)
• PDF computer format
• GIS Mapping Layers (ArcView)

5
Book Setup

• Currently there are a wide variety of setups
  across the state.
• DNR is working to establish recommended minimum
  standards.
• Page size 11 x 17

6
Overview map

• Shows entire county with townships delineated
  with page the township is on.

7
Zone page/structural page pairs.

• Structure Location
• Zone boundaries
• County, township, section boundaries
• Roads
• Rivers, streams, lakes
• Water Points
• Railroads, pipelines, power lines
• Map Legend
• Zone legend
• Color coded zone name
• Number of addresses in zone

Full county zone index

Structure Location

• At minimum, the structure point should be
  geo-coded (address matched) along the buildings
  address road.
• Ideally the structure location should be a point
  at the actual structure with an accompanying line
  from structure along driveway to main road access
  point for driveways over 200.
• On each page, with the legend, a small text note
  should briefly indicate how the structure
  location was determined (i.e. GPS, Geo-coded,
  etc.)

10
Zone Boundaries

• All structures should be within a zone.
• Limit should equal approximately 20 addresses per
  zone.
• Zones should connect so there are no un-zoned
  gaps on a road.
• Zones should follow the shape of the road as much
  as possible, but reach out away from the road far
  enough to included isolated structures.
• If a structure is at an intersection where 2 or
  more zones meet, if possible, it should be put in
  the zone on the road named in its address.

11
Optional

• Miscellaneous maps (county major road map,
  emergency districts, etc.
• Other indices may be included as deemed
  beneficial
• i.e.. County road index including
• Road
• Address range
• Township
• Page number

12
GIS Maps/Databases

• Structural database maintained by County Land
  Information.
• Zone layer maintained by DNR in areas of state
  that fall under DNR protection.
• Can be utilized at an ICP/EOC.
• Can hold more information than what map books can
  hold.

13
Information can be tied to GIS point
Columbia County
14
Adams County
15
Other info can be in database

• Hazardous materials permitted storage areas.
• Digital photo of structure.
• Tax parcel information.
• Anything else you may need/want.

20
Other potential uses

• Large area search and rescue (Wood County 2007).
• WMD/terrorist effected areas.
• Crowd control.
• Planned events (Ironman race, Summerfest, ESPN
  Games, etc).
• ERT/SWAT efforts (Virginia Tech, Beverly Hills
  (?) robbery)
• Anything that effects a few city/village blocks
  up to multiple counties.

21
One of the keys to a successfully run incident is
organization
22
Evacuation

• How do you organize and track evacuation
• in a large urban area?

23
Evacuation

• Or in an area that is 7 miles long and over 1
  mile wide?

24
Zone Mapping

• Zone maps help organize resources by giving them
  a specific area to concentrate on.
• Reduces duplication of efforts.

25
Zone Mapping

• Zone maps provide resources with number and
  location of addresses in their area of
  responsibility.

26
Zone Mapping

• Zone maps can be used to delineate areas of
  evacuation for a Reverse 911 system.

27
Where Do We Have Maps?
28
What does it take?

• Time
• - Potential federal grant funding (Hazard
  mitigation grant) in areas under DNR protection.
• Cooperation between departments
• Emergency Management
• County Sheriffs Dept.
• County Land Information
• County Zoning
• WI DNR
• Support from supervisors.

29
Updating

• County Land Information updates the database
  continually as new houses/businesses are built.
• Recommended to print new map books every 5 years.
• Sooner if major changes are made.
