Imminent hazard: what authorizes taking a tree down without notice
GO 95 Rule 18A classifies an imminent vegetation hazard as Level 1 and requires action immediately. The authority to cut comes from the recorded easement, the owner's consent, PRC 4295.5 after notice and an opportunity to be heard, or Civil Code 3502 abatement. Cutting without one exposes the company to treble damages under Code of Civil Procedure 733.
A Sunday in October, a 21 kV tap in Calaveras County, four days after the first real rain of the season. The patrolman photographs a ponderosa pine with a crack open in the soil on the uphill side of the root plate and a lean toward the center phase. The tree is 88 feet tall.
Its trunk stands 71 feet from the nearest pole, so it reaches the conductor with 17 feet to spare. The same trunk stands 26 feet outside a recorded easement that is a 20-foot strip. The gate is locked. The assessor's roll gives an owner in Reno.
Three hours of daylight are left and the tree should come down. Everything from here is a question about authority, and the vegetation stack answers less of it than the urgency suggests. The Commission's rules settle what the company owes and leave the ground it stands on to somebody else. The Public Resources Code settles the ground, and puts a condition on it that this crew has until dark to meet.
The finding is a Level 1, and Level 1 is the only clock in the order
GO 95 Rule 18 opens with a definition that fits this pine on its face:
For purposes of this rule, "Safety Hazard" means a condition that poses a significant threat to human life or property.
Rule 18A(1)(a) then attaches the duty. "Each company (including utilities and CIPs) is responsible for taking appropriate corrective action to remedy Safety Hazards and GO 95 nonconformances posed by its facilities." Rule 18A(2)(a) requires an auditable maintenance program that sorts those conditions into three priority levels. The first one reads in full:
Level 1: Immediate safety and/or reliability risk with high probability for significant impact. Take action immediately, either by fully repairing the condition, or by temporarily repairing and reclassifying the condition to a lower priority.
The word "immediately" appears once in Rule 18, and that is the occurrence. Everything around it is quieter than a reader expects. Level 2 carries a named decider, since its correction period is "to be determined at the time of identification by a qualified company representative," and four outside limits on that period:
six months for a fire risk in Tier 3 of the High Fire-Threat District
12 months for a fire risk in Tier 2
12 months where worker safety is compromised
59 months for every other Level 2 nonconformance
Level 3 says "Take action (re-inspect, re-evaluate, or repair) as appropriate." Level 1 stands alone in carrying a deadline with no date attached and no named decider.
It also offers an alternative that was clearly written for hardware. A Level 1 is discharged either by fully repairing the condition or "by temporarily repairing and reclassifying the condition to a lower priority," and Rule 18 leaves a temporary repair undefined. On a cracked crossarm the meaning is obvious. A ponderosa with a lifted root plate 26 feet outside the easement offers a crew nothing to repair. The tree belongs to the owner in Reno, and the crew's standing to touch it is the open question.
One more passage matters at 3 p.m. on that Sunday. Rule 18A(2)(b) says correction times "may be extended under reasonable circumstances, such as" third party refusal, customer issue, no access, permits required, and system emergencies. The list sits after all three levels, and its own words reach every one of them. Whether "no access" can extend a correction time of "immediately" is left open in the text, and the body that closes it is the Commission's Safety and Enforcement Division, on the audit, afterward.
Rule 18 never says tree
Search the rule for the word "vegetation" and the count is zero. Search it for "tree" and the count is the same. The order that supplies the only immediate deadline in the California stack was drafted around facilities and equipment, and it reaches a leaning pine by two different routes depending on what the pine is doing.
If the tree is inside the Table 1 clearance, the finding is a GO 95 nonconformance and Rule 18A applies on its face. If the tree stands well clear of the conductor and is simply about to fall across it, the clearance requirement is met. Rule 35's overhang provision says such trees "should be removed," and "should" sets an expectation where the clearance sentence sets a requirement. The condition is then a Safety Hazard, which Rule 18 defines on its own terms and which carries the same corrective duty.
Which level it lands in is the company's call, made against six factors that Rule 18A(2)(a) states and leaves unweighted:
Safety and reliability as specified in the priority levels below; Type of facility or equipment; Location, including whether the Safety Hazard or nonconformance is located in the High Fire-Threat District; Accessibility; Climate; Direct or potential impact on operations, customers, electrical company workers, communications workers, and the general public.
Every one of those is a description. Converting a lifted root plate into a level number is left to the person holding the camera.
So the Calaveras pine gets described four separate times in four separate vocabularies before anybody picks up a saw. Rule 18's three priority levels. The field guide's four likelihood-of-failure ratings. PRC 4293's list of conditions, which names trees leaning toward the line. Rule 35's list, which names dead, rotten and diseased material. Only the first of the four produces a deadline, and it is the one written entirely about facilities.
Every lawful way to cut starts on somebody's land
Six provisions in the stack touch this moment. Two of them authorize work, two of them excuse work left undone, and one is a property right rather than a rule at all.
Source | What it authorizes | The condition it carries |
The recorded easement | Whatever the grant says, over the ground the grant covers | The words of the instrument |
The owner's consent | The work consented to | Somebody with authority to give it |
Traverse, pruning to PRC 4293 clearances, and abatement by pruning or removal of hazardous, dead, rotten, diseased or structurally defective live trees | Notice and an opportunity to be heard; high fire threat district or state responsibility area only | |
Abatement of a private nuisance by removing or destroying the thing | No breach of the peace, no unnecessary injury | |
Relief rather than authority | Absence of legal right, or of consent | |
Relief rather than authority | Two documented artifacts |
All six carry their conditions into an emergency unchanged. That is the finding, and it holds even where the statutes sit two sections apart in the same code. PRC 4293 states the felling duty in mandatory terms: leaning trees that may contact the line from the side or fall on it "shall be felled, cut, or trimmed so as to remove such hazard."
Two sections later the same code withdraws the means. PRC 4295 relieves a person who lacks the legal right to maintain the clearing, and then adds a second clause that decides this Sunday:
nor do such sections require any person to enter upon or to damage property which is owned by any other person without the consent of the owner of the property.
PRC 4295.5, the one entry right in the chapter, was enacted after the 2017 fire season and still conditions entry on notice and an opportunity to be heard. The condition holds whatever shape the tree is in. What that section reaches and what it leaves compensable is its own subject.
Rule 35's four exceptions land in the same place. Each turns on something other than urgency, and the one that comes closest runs in the opposite direction:
The Commission recognizes that unusual circumstances beyond the control of the utility may result in nonconformance with the rules. In such cases, the utility may be directed by the Commission to take prompt remedial action to come into conformance, whether or not the nonconformance gives rise to penalties or is alleged to fall within permitted exceptions or phase-in requirements.
Exception 3 reserves a power to compel prompt action, and reserves it to the Commission.
Where imminent actually appears
The word is scattered across the stack and it attaches to a different object every time.
Where it appears | What it attaches to | What it changes |
A likelihood-of-failure rating on one tree | The urgency of the assessment, and nothing else | |
The CEQA definition of "emergency" | Whether environmental review is required of a public agency | |
The risk threshold for a de-energization decision | Whether a line stays energized | |
A vegetation condition likely to cause a Fault at any moment | Who gets a phone call, and how fast |
The field guide's entry is the one most often quoted in a hazard tree file. "Imminent: Failure has started or is most likely to occur very soon. Immediate action may be required." It names the action and stops there, which is consistent with what the guide is and easy to read as more than it is.
PRC 21060.3 is the one definition in play here that puts a boundary on the word, and it was written for a different purpose. "'Emergency' means a sudden, unexpected occurrence, involving a clear and imminent danger, demanding immediate action to prevent or mitigate loss of, or damage to, life, health, property, or essential public services." That sentence decides whether an agency has to write a document. It speaks to paperwork and stops at the property line.
Imminence changes what the company owes. It does not change whose permission the company needs.
The easement is the authority, and the statute assumes it
The clearest statement of where removal authority actually comes from sits inside a liability clause. PRC 4295.5(b) keeps a utility answerable for damages, and draws the line at one document: vegetation "not covered by an easement granted to the person for the electrical transmission or distribution line."
The legislature drew the carve-out around an easement because the easement is the baseline it assumed. Everything in the Public Resources Code sits on top of a recorded instrument, and the instrument decides the question the code declines to answer.
That is why the 26 feet in the opening matters more than the lean does. A 20-foot strip conveyed in 1948 may carry a danger-tree clause reaching trees outside the strip that could strike the line, or it may carry a right to clear within the strip and stop there.
Whether the crew may cut this pine before dark is a question about the words of a seventy-eight-year-old instrument rather than about fire behavior, and the answer sits in a title file rather than in a field guide. How far the right of way runs and what the easement actually conveys is worth settling long before a Sunday in October.
Inside that instrument's reach, advance notice is a matter of practice rather than of statute. PG&E says as much on its own public vegetation page: "We try to notify property owners before planned work as a courtesy.
In some cases, you may not get a notice." The same page adds, under what to expect during tree safety work, "If we find an urgent safety issue, we will address it right away." Both sentences describe work the company already holds the right to do, which is where PG&E's published description leaves the question.
What Civil Code 3502 actually gives a utility
Where the easement stops and consent is unavailable, the remaining route is the oldest one in the stack. Civil Code 3501, enacted in 1872: "The remedies against a private nuisance are: 1. A civil action; or, 2. Abatement." Then 3502, from the same year:
A person injured by a private nuisance may abate it by removing, or, if necessary, destroying the thing which constitutes the nuisance, without committing a breach of the peace, or doing unnecessary injury.
Three conditions are packed into that sentence, and a utility satisfies them unevenly. The abater has to be "a person injured," so the injury has to be to the company's own interest, which on this span is the easement and the conductor above it.
The abatement has to stop short of "unnecessary injury," so felling an 88-foot pine where removing a single leaning stem would answer the hazard is outside the section. And it has to happen "without committing a breach of the peace," which in the field means the route closes the moment the owner arrives and objects.
The section also has to be raised rather than relied on. It is a defense, asserted after an owner sues, and graded by a court on the record the crew left. California courts have put limits on self-help of this kind. In Booska v. Patel (1994) 24 Cal.App.4th 1786, the Court of Appeal considered a landowner who excavated along his own property line and severed the roots of a neighbor's Monterey pine.
The defendant argued an absolute right to cut anything crossing the line. The court held the right is bounded by reasonableness. A neighbor cutting on his own ground starts from a stronger position than a crew standing on somebody else's, and the court limited it anyway.
A wrong call is priced at three times the tree
Two statutes set the multiplier, and both have been on the books since 1872. Code of Civil Procedure 733 makes any person who cuts down a tree on the land of another "without lawful authority" liable to the owner "for treble the amount of damages which may be assessed therefor." Civil Code 3346(a) sets the same measure for wrongful injuries to trees, with one reduction worth knowing:
except that where the trespass was casual or involuntary, or that the defendant in any action brought under this section had probable cause to believe that the land on which the trespass was committed was his own or the land of the person in whose service or by whose direction the act was done, the measure of damages shall be twice the sum as would compensate for the actual detriment
A crew that cut in a good faith but mistaken belief that the pine stood inside the easement is arguing for double rather than treble. That is the whole benefit of the mistake, and it is a discount on an open number, since both statutes leave "actual detriment" undefined.
Heninger v. Dunn (1980) 101 Cal.App.3d 858 is the case that shows what the base number can do. The defendants bulldozed a road about seven-tenths of a mile long across the plaintiffs' land, acting on an attorney's advice that they held a valid easement. The advice was wrong.
The work killed or damaged 225 trees, and the trial court found the cost of replacing them to be $221,647, against a $5,000 increase in the property's market value. The Court of Appeal held that restoration cost could be awarded where the owners had personal reasons for restoring the land and the cost was not unreasonable in relation to the damage and the pre-trespass value. The multiplier in CCP 733 then runs on whichever base is found.
An erroneous easement opinion is exactly the failure this section describes, and a title file pulled before the saw is what forecloses it.
The step available on the company's own side of the line
At 3 p.m. on a Sunday, with a locked gate and an owner in Reno, one step sits entirely inside the company's own authority. It can open the line.
The CPUC states the basis plainly: "In 2012, the CPUC ruled that California Public Utilities Code Sections 451 and 399.2(a) give the electric IOUs authority to shut off the electric power to protect public safety." That statement is about the six investor-owned utilities the Commission names, and a publicly owned utility's switching authority comes from its own governing body rather than from that ruling.
De-energization is also what the federal standard expects when work is blocked. FAC-003-5 Measure M5 lists the acceptable evidence of corrective action for a constrained line:
Examples of acceptable forms of evidence may include initially-planned work orders, documentation of constraints from landowners, court orders, inspection records of increased monitoring, documentation of the de-rating of lines, revised work orders, invoices, or evidence that the line was de-energized.
Two of those eight are switching actions and one is a court order. What R5 asks for and when it fires belongs to the standard's own page; the point here is that the standard drafted for the highest-consequence lines in the country treats de-energizing as an answer rather than as a failure.
The device relief in Rule 35 Exception 1 answers a different problem. That exception separates a conductor from a tree "with suitable materials or devices to avoid conductor damage by abrasion and grounding of the circuit through the tree," which addresses contact. Eighty-eight feet of pine arriving across three phases is a different event. A line guard installed on this span produces a record that reads as a mitigation on paper alone.
So the interim disposition on the Calaveras tap is a switching order, a patrol interval, and a dated note saying why the tree is still standing. That combination is defensible. A closed work order claims a hazard that is still in the air.
An emergency permit waiver stops at the permit
Where a local ordinance requires a permit to remove a tree, GO 95 Rule 18A(2)(b) already names "permits required" among the reasonable circumstances that may extend a correction time, which is the Commission acknowledging the delay without excusing it.
Some counties waive the permit outright in fire season, and the terms of those waivers are instructive. The County of San Mateo has suspended tree removal permits and fees in the unincorporated Coastal Zone for the period July 1, 2026 to July 1, 2027. It covers eucalyptus, pine, acacia, tan oak and bay trees standing within 100 feet of a habitable structure or within 30 feet of a road needed for evacuation. The notice says "No notice to the County is required." The next line says this:
Person(s) who remove such tree(s) must have written permission from the owner of the propert(ies) on which the tree trunk is located.
The government's step is waived. The owner's step survives, upgraded to writing. That is the shape these exemptions take, and the CEQA exemptions take it too. PRC 21080(b)(4) and 14 CCR 15269(c) both exempt "specific actions necessary to prevent or mitigate an emergency," using the PRC 21060.3 definition. What they exempt is the environmental review a public agency would otherwise owe, which matters to a municipal utility and to a county issuing a permit. Consent sits outside both.
What the record has to name
Inside GO 95 the retention requirement that fires on this work is Rule 18A(1)(b), and it is short:
Upon completion of the corrective action, the company's records shall show, with sufficient detail, the nature of the work, the date, and the identity of persons performing the work. These records shall be preserved by the company for at least ten (10) years and shall be made available to Commission staff upon 30 days notice.
Three fields and a ten-year shelf. A file holding only those three leaves the auditor's first question open, which is why the tree was cut with the owner absent from it. The entries that close that out:
The span or pole identifier, and the tree located by trunk position rather than by where the crown sat.
The date and time the condition was first seen, by whom, and whether the knowledge arrived through a patrol or a phone call.
The priority level assigned, the person who assigned it, and which of Rule 18A(2)(a)'s six factors carried the assignment.
The authority relied on, named rather than implied: the recorded instrument by book and page, the consent with who gave it and when, or PRC 4295.5 with the notice artifact attached.
The measurement that decides whether the trunk stood inside or outside the easement, taken before the saw rather than reconstructed after it.
Where the tree was left standing that day, the interim action: the switching order number, the patrol interval, the reason, and which of Rule 18A(2)(b)'s circumstances the delay is claimed under.
The report to the responsible fire protection agency where access was the obstacle, by agency name and date, which is the step CAL FIRE expects on state responsibility area land.
The date the condition was closed, and by what work.
How those entries sit inside the rest of the clearance file and how long each one has to be kept are separate questions. The one that belongs here is narrower. A Level 1 on a tree standing outside the easement records two decisions: that the condition was immediate, and that the company was entitled to act on it. A file carrying both can explain a stump on somebody else's land ten years later.

Frequently asked questions
Can a California utility take down a hazard tree without notifying the property owner?
Only where it already holds the right. Inside a recorded easement the authority is the instrument, and no California statute requires notice before work the easement permits. Outside it, the routes are the owner's consent, PRC 4295.5 in a high fire threat district or state responsibility area after notice and an opportunity to be heard, or abatement of a private nuisance under Civil Code 3502. None of the three has an emergency branch that drops the condition on it.
What does GO 95 Rule 18 require when a hazard tree is an immediate risk?
Rule 18A(2)(a) defines Level 1 as an immediate safety and/or reliability risk with high probability for significant impact, and requires the company to take action immediately, either by fully repairing the condition or by temporarily repairing and reclassifying the condition to a lower priority. That is the only use of the word immediately in Rule 18. The rule sets no date, names nobody who assigns the level, and never uses the words vegetation or tree.
Is there an emergency exception to PRC 4295 or PRC 4295.5?
No. PRC 4295 says sections 4292 and 4293 do not require any person to enter upon or damage property owned by another without the consent of the owner, and states no exception for urgency. PRC 4295.5, enacted after the 2017 fire season, conditions its right of entry on notice and an opportunity to be heard and carries no carve-out for a tree that is about to fail.
What is the exposure for removing a tree the utility had no right to remove?
Code of Civil Procedure 733 makes a person who cuts down a tree on the land of another without lawful authority liable to the owner for treble the damages assessed. Civil Code 3346(a) sets the same multiplier for wrongful injuries to trees, reduced to double where the trespass was casual or involuntary or the defendant had probable cause to believe the land was his own. PRC 4295.5(b) separately preserves liability for removal of vegetation not covered by the easement.
