Wildland Urban Interface
B y P a u l S h a p i r o T he following information is quoted from FIRE- SCOPE, which is an organization the state of California put together to have plans in place for major disasters—wildland fires being one of them. To give you a better idea of what anchor and hold is all about, I have quoted the definition given by FIRESCOPE.
ANCHOR AND HOLD
Anchor and hold is a tactic using control lines and
large water streams from fixed water supplies in an
attempt to stop fire spread. The goal is to extinguish
structure fires, defend exposures, and reduce ember

siderable planning and effort and uses both fixed
and mobile resources.
– Fixed engines should be spotted in safe areas
where they can safely withstand any fire
– Mobile engines or task forces can engage in
individual structure defense actions or perimeter
control and resupply from fixed water sources.
– Mobile engines should be prepared to redeploy
to other areas should the fire escape the anchor
and hold line.
• Ground resources, such as engine crews and hand
crews, should staff hoselines and be prepared to
extinguish hot spots, fire perimeter, and structures.
– Hand crew Strike Teams should be deployed to
construct fire control lines wherever needed and
conduct firing operations.
The anchor and hold strategies presented in this
section are based on the five following factors:
1. Can it be done safely?
2. Is there an adequate water supply?
3. Is there adequate staffing?
4. Is there adequate equipment?
5. Is there a will to get the job done?
The anchor and hold tactics involve fire suppression
units connecting to a hydrant to maintain an uninter-
