Get Your San Dimas Estimate: (626) 325-0896🛑 Read this before you cut a tree in the SGV: Several San Gabriel Valley cities protect native oaks, sycamores, and designated landmark trees, including trees standing on private property. Removing or severely trimming a protected tree without a permit can bring fines and mandatory replacement plantings. The rules change at every city line. Confirm what applies to your lot before any crew starts an engine.
Whose Tree Is It in San Dimas?
City of San Dimas Planning Division
Oaks 8 inches & mature trees 10 inches up
That's what gets special treatment in San Dimas. Touching a protected tree without the right paperwork is the expensive way to learn the ordinance. The crews we dispatch answer the permit question before quoting the cut.
Parkway & Street Trees
City-Owned
The tree in the strip between your sidewalk and the curb is almost always the city's, even though you water it. Removing or topping one on your own can mean fines. We tell you whose tree it is before anyone climbs it.
Topping vs. Proper Crown Work
| What Happens | "Topping It Off Cheap" | Proper Crown Thinning & Reduction |
|---|---|---|
| Regrowth | Dense, weakly attached shoots that snap in wind | Natural branch structure that holds in Santa Ana gusts |
| Tree Health | Large open wounds invite rot, borers, and dieback | Cuts at the branch collar that the tree can close |
| Long-Term Cost | Re-cut every 2–3 years, often ends in full removal | Maintenance cycle stretches to 3–5 years |
| Curb Appeal | Hat-rack stubs and a scalped silhouette | Full canopy kept, shade kept, value kept |
Working in San Dimas: What to Know
The Canopy
San Dimas built out Via Verde through the 1970s and the bill is coming due: pines, eucalyptus, and other landscape trees hitting fifty years old all at once, many never structurally pruned. Old eucalyptus windbreaks from the citrus era still line some of the older rural lots, and big eucalyptus drop limbs without warning in summer heat. Arborists call it sudden branch drop, and August is when it happens.
The Rules
City of San Dimas Planning Division
San Dimas has its own tree preservation ordinance, on the books since 1990: removing an oak eight inches across, or most other mature trees at ten inches, takes a city permit even on private land. The equestrian lots add their own concern, because limb drop over corrals and arenas is a liability question, not just a cleanup. Canyon-adjacent parcels also carry fire clearance duties each season. We walk through the line items before quoting, not after.
