Folsom FAQ
Can I top my oak tree that's getting too big?
No. Topping native oaks is prohibited in Folsom — it causes decline and stress. Hire an ISA-certified arborist to do proper crown reduction pruning under an approved permit if needed.
Do I need a permit to trim my Folsom street tree branches?
Street trees (in the public right of way) are owned by the city. Contact Folsom Parks & Recreation for any trimming — do not prune them yourself.
Isleton FAQ
Can I trim my own street-overhanging branches?
Yes, but you must keep them clear of the street and sidewalk. For power line clearance, contact PG&E, not a private arborist.
Who trims trees near the levee?
Reclamation District 407 manages vegetation in the levee prism and may remove trees that threaten levee integrity.
