Tree Service in Topanga, CA
Topanga is a canyon town of oaks, a free-running creek and a long fire history, and the County sets the rules for its trees. Steep lots make tree service in Topanga careful work, whether we trim or remove.
Tree care in Topanga
Oak woodland, a free-running creek, and fire
Topanga has no city hall, so the County sets the rules for your trees. About 8,560 people live across 19 square miles of canyon. Oak woodland and coastal sage scrub cover the slopes, and Topanga Creek still runs free, with no dam. Cottages went up here in the 1920s as weekend getaways, and artists came in the 1960s. Fire is part of life: a 1993 fire burned through, and the 2025 Palisades Fire destroyed most homes near the state beach. Winter rain can bring floods and mudslides.
On a steep lot, the tree that worries you most is the one between the house and the road.
Who governs tree work in Topanga
Los Angeles County (unincorporated)
Topanga has no tree ordinance of its own — it is governed by Los Angeles County (unincorporated), and that jurisdiction's rules apply here. The OTP applies to all protected oak trees in unincorporated communities within LA County. In the existing OTP, no permit is required for pruning oak tree branches and roots no larger than 2” in diameter. All impacts to heritage oak trees require an Oak Tree Permit with a public hearing. Rules change. Confirm current requirements with the jurisdiction before work begins — filing a permit is the property owner's responsibility, not ours.
The list
Topanga oaks pruned lightly, dead limbs cleared, steep trees removed
Supreme Tree Experts prunes oaks, clears dead limbs and removes trees in Topanga, where oak woodland covers the canyon slopes. Oaks can need a permit, so Topanga owners have each oak marked before any cut by Supreme Tree Experts.
Tree Removal
We take down dead and hazardous trees on Topanga's steep lots, lowering wood toward the road. Topanga has no city, so the County's Oak Tree Permit rules apply. We mark every oak first, since removing one needs a permit that the owner files.
Tree Trimming & Pruning
Our crews prune oaks lightly and thin other trees back from the house and the road. The rules allow cuts on oak branches and roots no larger than 2 inches without a permit. Bigger oak cuts wait until the owner has one.
Stump Grinding & Stump Removal
Burned stumps near the state beach get ground down by our crew so rebuild lots are clear. The 2025 fire destroyed most homes in the lower canyon. Grinding below the soil readies the ground for building or new planting.
Palm Tree Trimming & Skinning
Palms here get their dry fronds and fruit stalks cut by our crew before fire season. A 1993 fire burned through the area, and dry fronds near a home are easy fuel. Where our lift truck can reach, we skin the trunk from crown to base.
Emergency Tree Service
When a tree falls across your drive, onto the house or over a road, our crew comes 24/7. Storms here can bring mud and rockfall along with the trees. We clear the way first, then chip the wood on the spot.
Tree Maintenance
Our crews check trees above homes and drives each year for lean and root hold. Heavy winter rain soaks steep soil, and slopes here can slide. A tree on loose ground can tip when the slope gives way.
Tree Height Reduction
We reduce tall trees other than oaks, making each cut at a strong side limb, never topping. Heritage oaks are different, since any impact on one needs a permit and a public hearing. We flag those before planning cuts.
Estate Tree Care
We set long-term plans for large, wooded lots that track each oak and every other big tree. Oak woodland covers much of the slopes. Work goes in small steps, season by season, so the woodland stays whole.
Tree Shaping & Shrub Shearing
Our crew cuts back shrubs near the house and keeps garden hedges in shape. Coastal sage scrub grows thick on the slopes around many homes. Keeping it trimmed back from walls and eaves cuts the fuel close to the house.
Landscaping
We plan planting that holds the soil and stays well back from the water. Topanga Creek still runs free, with no dam, and drains a large watershed. Check the rules first if you plan big changes near the bank.
Hardscape
We build paths, steps and low walls on hillside lots with a firm base and good drainage. Steep drives and narrow roads mean our crew plans every load in advance. Each piece is built to shed water and stay put on the slope.

Steep slopes and old oaks: what our crew brings to Topanga
Tree work goes wrong when it is rushed or under-equipped. We run our own 75-foot boom trucks, lift trucks, chippers and stump grinders, and every crew works under an ISA Certified Arborist — so the job gets done right the first time.
We hold California license #1002853 for both landscaping and tree and palm work, we are bonded, we carry general liability and every employee is on workers’ compensation.
ISA Certified Arborist
Our arborist walks the slope with you, marks every oak and notes which trees stand close to the house. The estimate is free.
Licensed, Bonded & Insured
Canyon work is risky for any crew. We carry state license #1002853 for tree service and landscaping, a bond, and insurance for each worker on your slope.
Southern California Since 1985
Topanga's cottages from the 1920s are older than we are. Our family business dates from 1985 and is still family-owned.
Our Own Equipment
Our own 75-foot boom trucks reach up and over steep lots from the road, and our own chippers turn cut brush into chips on the spot.

Before you book in Topanga
6 questions worth having answered before you book tree work in Topanga. If yours is not here, call 877-787-7363 and ask.
Los Angeles County, not a city. Topanga is unincorporated, so the County's Oak Tree Permit rules apply. Small cuts are allowed, but big work on an oak, and any work on a heritage oak, needs a permit. The owner files it. An arborist can tell you which of your trees are oaks.
The Palisades Fire hit the lower canyon hardest. Most homes near Topanga State Beach were destroyed. Owners there face burned trees, bare slopes and rebuild plans. Burned trees near a road or a home site are often the first ones to deal with.
Heavy winter rain soaks steep hillside soil. Topanga sees flooding and mudslides after big storms. In 2005, a 300-ton boulder blocked the main road. Trees on loose slopes can tip when the ground gives way. We check lean and root hold on trees above homes and drives.
Yes, with care. Topanga Creek drains the third-largest watershed that flows to the bay, and it is one of the few undammed streams left in the area. Keep new trees and paths back from the water, and ask the County first if you plan big changes near the bank.
Yes — $600 for tree services, wherever the job is. Steep drives, long carries and narrow roads shape most of the price here.
Yes, 24/7. Storms here can bring mud, rockfall and falling trees across a road. Call 877-787-7363.
