Tree Law: The "Top Ten" Issues Attorneys Should Consider When Handling Disputes Over Trees

It is a familiar story. A client comes into a lawyer's office, complaining that his neighbor has just hacked his trees without his
permission, and wants legal representation. Although the lawyer has never handled a "tree case," she has practiced civil
litigation for years, maybe even in real estate litigation, and feels confident in her abilities to fight the good fight. She says to
herself, "How hard could it be?" But after one year, tens of thousands of dollars in legal fees, and a very disappointed client,
the lawyer tells herself that she won't ever handle another tree case.
What went wrong? Why are tree cases so thorny? What can lawyers do to help their clients obtain quicker, more cost-effective results? In California, where trees are plentiful, homes are close to each other, and homeowners often have a
disproportionate sense of entitlement, the number and variety of tree disputes are enormous. Whether the issue is one of trees
blocking views, roots lifting driveways, trees causing property damage or personal injury, trees dropping debris, or acts of
vandalism against trees, it is important not to underestimate the complexities of the dispute when initially deciding whether to
take the case and how to get the best result.
1. Getting to the root of the problem. Tree problems usually fall under the heading of neighbor disputes, which tend to be
rancorous and even downright nasty. It is not unusual, therefore, for the client walking through your door to be angry and
distraught. For many anxious clients this will be their first foray into the legal world.
After listening to the client's story, it may be tempting to launch into giving advice and concocting solutions to the
"problem." After all, that is what lawyers do best. Slow down and beware. It is important first to find out what the client
wants to achieve. This may be the first time he or she actually stops to think about it. Because our judicial system is limited in
the kind of remedies it can provide, it is important to know whether the client's objectives are reasonable. Beware of clients
who say they want retribution, retaliation, or even respect. If, after exploration, the client's expectations do not match your
repertoire of remedies, declining representation will be the best thing for both of you.
2. Consult an expert on damages and liability. Ordinarily in civil cases we do not think of retaining expert witnesses until
well into the case. With certain types of tree cases, however, it may be appropriate to retain a qualified Consulting Arborist
before even deciding whether to take the case. For example, in the case of a neighbor who cut your client's trees without
permission, liability may be clear—but what are the damages? You may think the trees do not have much value, but it turns
out that more than $50,000 worth of damage was done. Conversely, you may assume that a particular tree has great value, but
it turns out that, because of its species, condition, or location, it barely qualifies for small claims court. Whatever the tree's
value, keep in mind that
"[c]ourts have stressed that only reasonable costs of replacing destroyed trees with identical or
substantially similar trees may be recovered." Hassoldt v Patrick Media Group, Inc. (2000) 84 CA4th 153, 168, citing
Heninger v Dunn (1980) 101 CA3d 858, 865.
In other types of disputes, the damages may be clear but liability may be a question. For example, in a case concerning a
hazardous tree smashing a house or car, did the tree fall because of something the tree owner knew or should have known
about the tree? Knowing the answers to such questions in advance will help you decide whether to take the case and how best
to proceed.
Do not confuse a certified arborist with a Consulting Arborist. Anyone who passes the test administered by the International
Society of Arboriculture, the trade organization for the arboricultural industry, may become a certified arborist. While there
are many certified arborists who may be qualified to serve as consultants, there are many more whose only qualification is
that they have a pickup truck and a chainsaw. A Consulting Arborist with forensic training, regardless of "certification," is the
appropriate expert to look at questions of causation and valuation. To find a qualified Consulting Arborist
in your area, contact the American Society of Consulting Arborists in Rockville, Maryland, at 301/947-0483
(asca@mgmtsol.com) or check their online referral database at www.asca-consultants.org. You could also consult a local
attorney specializing in tree disputes for recommendations.
3. Know your statutes and ordinances. State statutes regarding trees span six codes. Here are just a few examples: Civil
Code section 3346 and Code of Civil Procedure section 733 provide mandatory doubling (with certain exceptions) and
discretionary trebling of damages for wrongful injury to trees and vegetation. They also provide a five-year statute of
limitations. Penal Code sections 384a and 622 make it a crime to harm or remove trees or plants on land not your own, which
is punishable by a fine of up to $1,000 and imprisonment in jail up to six months.
In addition, most municipalities have tree ordinances. Many communities have "heritage tree" ordinances that govern the
type of trees that can be cut or removed, even by the property owner. Protected trees are often defined by size, age, or
species. There is little uniformity in these ordinances, and one community's heritage tree can be another community's
undesirable species. For example, the city of Mill Valley, known for its majestic redwoods, protects redwood trees of a
certain size, while the city of Sausalito, known for its majestic views, lists redwoods as an undesirable tree because it is a
fast- and tall-growing species. The city of Novato defines its heritage trees as anything larger than 24 inches in diameter (75
inches in circumference) regardless of species.
Although there is no common law right to a view in California (see Wolford v Thomas (1987) 190 CA3d 347, 358-359),
some properties are subject to a view easement. Many towns have adopted view ordinances, and courts have agreed that
advancing aesthetic values is a legitimate exercise of police powers. But do not look for uniformity in these ordinances either.
Each one has its own requirements regarding how the ordinance is applied, what views are protected, the factors to be
balanced, and the alternative dispute resolution requirements, if any, to be pursued. If drafted correctly, such ordinances pass
constitutional muster. See, for example, Kucera v Lizza (1997) 59 CA4th 1141 (Tiburon view ordinance supports valid police
power goal of preserving views and sunlight); Echevarrieta v City of Rancho Palos Verdes (2001) 86 CA4th 472 (ordering
appellant to trim trees for neighbor's view did not violate takings clause).
Remember to ask whether the property in question is located in a planned development or governed by a homeowners'
association. There may be contractual covenants, conditions, and restrictions (CC&Rs) regarding trees and views that apply.
Another complication can arise if solar panels are being blocked, if that is contrary to ordinance or agreement.
4. Who owns the trees? This seems like an obvious question. And it is certainly a critical piece of information. However,
asking your client this question is just the beginning of the inquiry. Often the client's answer will be based either on an
incorrect understanding of the legalities of ownership or an incorrect understanding of the property lines. Civil Code section
833 provides that a tree whose trunk stands wholly on the land owned belongs exclusively to that owner. So you must
determine where in relation to the property line the trunk meets the ground, regardless of where the roots or branches grow.
Civil Code section 834 provides that trees whose trunks stand partly on the land of two or more coterminous owners belong
to them in common. This gives rise to joint rights and responsibilities.
People often assume that the property line is the fence line. While this assumption may be correct, if there is any doubt about
ownership, a line survey should be ordered at the beginning of your representation.
5. Don't shoot first and ask questions later. One of the first questions I ask my clients is whether they have spoken to the
other side about their concerns. I am always surprised by the number of times the answer is no. Because your client will
continue to live next door to these neighbors for some period of time (maybe even the rest of their life), it is important to find
ways of preserving that relationship. Although sending the "lawyer letter" may make the client feel good in the short term, it
can do irreparable damage. Encourage the client to personally contact the neighbor to talk about the problem. It may turn out
that the neighbor was unaware of the problem and may be quite willing to accommodate your client in some way that is
satisfactory to both sides. You can help set up the client for success by role-playing this conversation with your client.
6. It's not about the trees. Very often disputes about trees have their genesis in something completely different. Perhaps
your clients did not invite the neighbor to their daughter's wedding; or the neighbor, an older person who has lived there for
40 years, does not like being told what to do by your twenty-something clients who moved in six months ago; or perhaps
your clients angered the neighbor by challenging a remodeling or construction project five years earlier. Getting beneath the
parties' positions to their needs will often reveal the keys to a mutually agreeable solution.
7. Insurance considerations. Insurance may play a role in resolving tree disputes. If your client's property is damaged by a
neighbor's tree, the client's homeowner's policy should cover the damage to the house, other structures, vehicles, trees,
plants, pavement, walkways, drives, furniture, and personal belongings. The tree owner's policy may also provide coverage
under the liability portion of the policy. Carriers will try to avoid damage claims caused by falling trees by claiming they do
not cover "acts of God." However, this defense is extremely difficult to establish. It requires an event so unusual in its
proportions that it could not be anticipated. See Mattos v Mattos (1958) 162 CA2d 41 (windstorm was not of sufficient
intensity to be "act of God"). And even in such an event, the defendant will not be relieved of liability if his or her own
negligence contributed to the damage.
When trees have been cut or vandalized, a tree owner's insurance usually covers damage to the trees up to a certain dollar
amount. Many policies pay up to $500 a tree or 5 percent of the total property value. The tree cutter's insurance may also
provide coverage unless the carrier determines that the cutter acted "intentionally."
8. Discourage self help. A common assumption is that people have an absolute right to cut offending branches or roots that
encroach on their property. This assumption should have been dispelled in 1994 when an appellate court held that there is no
absolute right to sever encroaching roots; rather, the test is one of reasonableness. Booska v Patel, 24 CA4th 1786. Thus a
landowner's right to remove the portions of a tree that encroach on his or her land must be balanced against the obligations to
act reasonably toward adjoining landowners and to refrain from causing foreseeable injury to neighboring property.
California Civil Practice, Real Property Litigation 11:42 (West, 2001). A landowner is responsible "for an injury
occasioned to another by his want of ordinary care or skill in the management of his property or person, except so far as the
latter has, willfully or by want of ordinary care, brought the injury on himself." CC 1714. See also CC 3514 (general
obligations to others).
9. The expanding duty of care. When establishing liability for damage caused by trees, ownership is a starting point but not
the end of the inquiry. Other potentially responsible parties include those who possess the land on which the trees grow or
exercise control over the trees. For example, maintaining trees, even if they are not yours, may be sufficient to give rise to a
duty of care to others.
The landmark case of Husovsky v U.S. (DDC 1978) 590 F2d 944 involved a motorist who was badly hurt when a tree limb,
weighing nearly ten tons, fell onto his car. The tree was located on embassy land in Washington, D.C., owned by the
government of India, and subject to an agreement that amounted to an easement for the benefit of the United States. The land
was controlled and maintained by the federal government, and was indistinguishable from the contiguous national park. The
road through the park was jointly maintained by the District of Columbia and the National Park Service. The court found that
the United States, whose duty it was to maintain and service the park, owed a duty of reasonable care to avert hazards that
could be dangerous to passing motorists.
California has been making its own forays into this expansion. In 1997 the state Supreme Court affirmed the possibility of a
duty owed by a landlord to a tenant who was injured, on land not owned by the landlord, by stepping in a broken or
uncovered utility meter box that was located in a narrow strip of city-owned lawn in front of the landlord's property. The
landlord had sometimes mown the lawn prior to the incident, and he had built a fence around the entire lawn, including the
city-owned portion, after the incident. The landlord argued that no duty was owed since he did not own the strip of land, nor
did he exercise any control over the meter box. Although the trial court agreed, the Supreme Court found in a 4-to-3 decision
that the evidence of mowing and fence-building presented a triable issue of fact regarding whether this type of maintenance
could constitute sufficient control to give rise to a duty. Alcaraz v Vece, 14 C4th 1149. The court noted, "[t]he proper test to
be applied to the liability of the posessor of land is whether in the management of his property he has acted as a reasonable
man in view of the probability of injury to others. This duty to maintain land in one's possession in a reasonably safe
condition exists even where [sic] the dangerous condition on the land is caused by an instrumentality that the landowner does
not own or control." 14 C4th at 1156.
Although evidence of maintenance of adjacent property is relevant to the issue of control, mere "neighborly maintenance" of
a sidewalk planting strip—even tree trimming and gardening—in front of a residence does not create a duty to a pedestrian
who trips and falls there. Contreras v Anderson (1997) 59 CA4th 188. The critical question is whether the adjoining
landowner took action to preclude or limit the actual owner's control of its own property. A landowner who has control over
the cause and repair of a defect in a sidewalk does have a duty to warn pedestrians or repair the defect. Alpert v Villa Romano
Homeowners Ass'n (2000) 81 CA4th 1320.
10. Promote the Golden Rule. Clients sometimes need to be reminded to treat their neighbor as they would like to be treated. While there are cases that will find resolution only before a judge or jury, in general it is in your client's best interest to avoid escalating neighbor disputes into litigation. Explain to your clients that court victories can be largely Pyrrhic, won at excessive monetary, emotional, and social cost. The lawyer who can solve problems through creative alternatives to litigation performs a service not only for the client but for the community at large.
