Pre-Evacuation Property Preparation: The Complete Guide

Pre-evacuation property preparation is the disciplined process of placing a wildfire-exposed property, its active protection systems and its supporting infrastructure into the best practical condition before occupants and staff leave. The objective is not to delay evacuation or encourage anyone to remain in hazardous conditions. It is to complete a preplanned set of safe, time-limited actions while evacuation routes remain open and before official orders require immediate departure.

Life safety comes first

No property-protection task is more important than early evacuation. Owners, occupants, caretakers and staff should follow official instructions and leave immediately when ordered. Preparation work should stop whenever smoke, flame, falling embers, road congestion, changing wind, equipment failure or responder direction makes continued activity unsafe.

A strong plan distinguishes between tasks that can be completed days in advance, tasks that can be completed during heightened readiness and tasks that are only appropriate when there is adequate time before evacuation. It should also define a hard stop after which no one remains to protect equipment or complete unfinished work.

Integrate preparation with the emergency operating plan

Pre-evacuation preparation should be a specific operating phase within the property’s wildfire emergency operating plan. It should identify who has authority to begin preparation, who confirms system status, who communicates with the owner and when the final departure decision is made.

The plan should use clear readiness levels rather than relying on vague judgment. A typical progression may include:

• Seasonal readiness: routine maintenance, vegetation work and supply verification.
• Elevated readiness: wildfire nearby, red-flag conditions or increased local activity.
• Pre-evacuation preparation: credible threat to the property or likely evacuation.
• Immediate evacuation: all preparation stops and personnel depart.

Establish activation criteria

The property plan should define the conditions that trigger pre-evacuation work. These may include official warnings, proximity of the incident, projected fire movement, expected wind, road conditions, local emergency notifications, utility interruptions or direction from a designated property manager.

Activation criteria should be conservative. Waiting until fire is visible from the property can eliminate the time needed to prepare safely and can place personnel in conflict with evacuating traffic or responding apparatus.

Assign roles and a final departure authority

Every task should have an assigned role rather than a general instruction that “someone” complete it. Common roles include:

• Incident lead or property manager
• Active-system operator
• Water and pump-system lead
• Power and generator lead
• Structure and exterior-preparation lead
• Animal, vehicle or equipment lead
• Communications and accountability lead

One person must have authority to terminate preparation and order departure. This authority should not depend on owner approval if communications fail or conditions deteriorate.

Prepare the active wildfire protection system

Where a property has an exterior sprinkler, deluge, misting or other active wildfire system, preparation should verify that the system is ready to operate without further hands-on work.

Typical checks include:

• Confirming the control system is online and free of unresolved alarms
• Verifying the intended operating mode and activation logic
• Confirming every required node, valve or protected area is available
• Checking that nozzles are unobstructed and have not been moved or damaged
• Confirming isolation valves are in their documented operating positions
• Verifying remote control, monitoring and notification paths
• Confirming any required manual-start instructions are available off-site

A full discharge test may not be appropriate during an active threat if it consumes limited water or creates a system reset requirement. The emergency plan should state which verification tests are acceptable during pre-evacuation conditions.

Confirm water availability and reserve

Water must be available in the quantity, quality and configuration assumed by the system design. Preparation should verify the actual status of cisterns, wells, pools, ponds, municipal connections and transfer systems.

Key actions may include:

• Confirming tank level and usable reserve
• Stopping nonessential water use
• Refilling reserves when time and supply allow
• Verifying makeup-water and transfer-pump operation
• Checking suction and discharge isolation valves
• Confirming filters are clean and differential pressure is acceptable
• Ensuring strainers, intakes and floating pickups are clear
• Documenting any reduction in expected runtime

The preparation plan should prohibit last-minute changes that defeat the engineered water strategy, such as opening undocumented bypasses or connecting unverified pumps and hoses that can reduce pressure to the permanent system.

Prepare pumps and pressure systems

Pumps should be placed in their intended emergency operating condition. This includes confirming electrical supply, controller status, pressure settings, priming conditions and the absence of active faults.

For multiple-pump systems, confirm the lead, lag and standby sequence. For well-fed systems, verify that expected well output remains available and that domestic or irrigation demands will not prevent the wildfire system from meeting its required flow.

Portable pumps should only be included when they have a defined suction source, fuel supply, connection method, operating procedure and assigned operator. Equipment that requires complicated assembly during evacuation should not be treated as dependable protection.

Prepare primary and backup power

A wildfire protection system may become unavailable if utility power fails. Pre-evacuation preparation should verify all intended power sources and transfer methods.

Tasks may include:

• Confirming utility power is present
• Checking battery state of charge
• Verifying inverter, charger and transfer-system status
• Testing generator readiness without unnecessarily interrupting the system
• Confirming fuel level and estimated runtime
• Removing nonessential loads from emergency power
• Verifying that pump starting demand is supported
• Confirming communications and controls remain powered during transfer

Fueling should occur well before immediate evacuation. Refueling a hot generator or transporting fuel during rapidly changing conditions can create additional hazards.

Reduce immediate ember exposure around structures

Last-minute exterior preparation cannot replace permanent home hardening and defensible-space work. However, when completed early and safely, targeted actions can remove temporary fuels and reduce obvious ember traps.

Property-specific tasks may include:

• Moving combustible furniture, cushions, mats and decorations indoors
• Removing cardboard, firewood, lumber and waste near structures
• Clearing leaves and needles from decks, patios, gutters and drains
• Closing exterior doors, windows and pet doors
• Closing or deploying listed shutters where provided
• Moving grills, propane cylinders and portable fuel containers away from structures
• Relocating combustible vehicles and equipment from attached structures
• Closing garage doors after vehicles and equipment are removed

No one should climb onto a roof, enter hazardous terrain or begin major vegetation work during an active evacuation period.

Manage propane and exterior fuel sources

Propane tanks, fuel storage and exterior gas equipment should be addressed through a documented property-specific procedure. Staff should not improvise by shutting valves or disconnecting systems unless those actions have been reviewed and trained in advance.

The plan may include clearing combustible material around tanks, closing appliance supplies, moving portable cylinders and verifying that access for responders is not blocked. Permanent tank placement, vegetation separation and protective features should be addressed before wildfire season.

Prepare access for evacuation and responders

Driveways, gates and turnarounds must remain usable for both departing occupants and arriving responders. Preparation actions may include:

• Opening gates or placing them in the documented emergency mode
• Confirming emergency access codes and overrides
• Removing vehicles, trailers and equipment from narrow approaches
• Keeping turnarounds and hydrant or tank connections clear
• Ensuring the property address is visible
• Securing livestock gates without blocking fire apparatus
• Providing responders with a concise property information sheet

Automatic gates should be evaluated for utility failure. A gate that defaults closed during an outage can obstruct both evacuation and emergency access.

Position vehicles for immediate departure

Vehicles should be fueled, loaded and positioned facing the evacuation route. Keys should remain with the assigned driver, and no vehicle should be parked where it blocks fire-system equipment, water connections or apparatus access.

Critical documents, medications, communication devices and evacuation supplies should be loaded before pre-evacuation conditions whenever possible. Property preparation should not delay personal evacuation packing.

Animals and livestock

Animal evacuation often requires more time than anticipated. Trailers, halters, carriers, medications and destination arrangements should be ready before a wildfire threatens the property.

The plan should define an early trigger for moving animals and a point beyond which no one returns for additional animals or equipment. Gates and pastures should not be opened in a way that creates hazards on public roads or blocks emergency access.

Secure critical property information

Off-site personnel should have access to the current system documents needed to monitor or operate the property after evacuation. This may include:

• Site plan and protected-area map
• Valve and isolation map
• Water-source and reserve information
• Pump and power-system instructions
• Control-system access and escalation contacts
• Emergency responder information sheet
• Current impairment and deficiency list
• Photos showing final property condition

Sensitive credentials should be stored securely and shared only with authorized operators.

Use a timed checklist

A pre-evacuation checklist should be organized by priority and available time. A useful structure is:

• Complete at elevated readiness: tasks that require substantial time or outside vendors.
• Complete before departure: high-value tasks that can be finished quickly and safely.
• Complete only when time permits: lower-priority actions that must never delay evacuation.
• Do not attempt: dangerous or labor-intensive activities prohibited during an active threat.

Estimated completion times should be tested during drills. A checklist that appears short on paper can take much longer when multiple buildings, gates, pumps and vehicles are involved.

Document the final property condition

Before departure, the incident lead should record the condition of the property and the protection system. The record may include:

• Departure time
• Names of personnel accounted for
• System operating mode
• Water level and estimated reserve
• Power-source status
• Generator fuel level
• Known impairments
• Gate and access condition
• Photos of key equipment and structures

This information supports remote operators, emergency responders, post-incident inspection and insurance documentation.

Remote operation after evacuation

Remote operation should be based on pre-established sequences rather than improvised commands. The plan should identify who can activate the system, which data must be reviewed before activation, how water is allocated and what occurs when communications are lost.

Remote monitoring is valuable, but it should not create false confidence. Cameras, sensors and cellular connections can fail during fire conditions. The property should be left in a condition that does not depend on continuous remote intervention.

Establish a hard stop

The plan should define a non-negotiable departure trigger. Examples include an evacuation order, fire entering a defined distance, a specific road condition, falling embers, visibility loss, loss of communications or direction from emergency personnel.

Once the hard stop is reached, no additional property task should be attempted. Personnel should depart together when practical and confirm accountability from a safe location.

Technical FAQs

Should exterior sprinklers be activated before evacuation?

Activation timing should follow the engineered operating sequence and the property’s emergency plan. Activating too early can deplete limited water, while activating too late may reduce effectiveness. The correct trigger depends on water reserve, system design, fire behavior, automation and the expected duration of exposure.

Should the entire property be wetted down before leaving?

Broad manual wetting is often temporary and can consume water needed by the permanent system. Priority should be given to the designed protection strategy and removal of combustible material. Any pre-wetting procedure should be supported by the site’s water budget.

Should gas and electricity be shut off?

Utility shutdown procedures are property-specific. Improper shutdown can disable pumps, controls, communications or critical building systems. The emergency plan should define which services remain on, which loads are removed and who is authorized to make changes.

Can staff remain to operate the system?

Active wildfire systems should be designed and prepared to operate without exposing personnel to hazardous conditions. Staff should not remain solely to operate equipment once evacuation is warranted.

How often should the checklist be practiced?

At least annually before peak wildfire season, and whenever the property, staffing, system design or access arrangement changes. Complex estates may benefit from separate tabletop and field drills.

What should happen after evacuation?

Authorized personnel should monitor available system data, maintain communication with emergency officials, document system events and avoid returning until authorities permit access. Post-incident inspection should occur before the system is reset or returned to normal service.
