Folsom has a strong tree preservation ordinance protecting native and heritage trees. Routine maintenance pruning (under 25% of canopy) is generally allowed without permit, but major trimming, topping, or pruning of protected trees requires an arborist report and Community Development permit. SMUD governs utility-line clearance trimming.
Folsom Municipal Code protects native oaks (Quercus species), heritage trees, and trees in required landscape areas. Permissible without permit: removal of dead wood, crossing branches, and minor shaping not exceeding 25% of live canopy in any 12-month period. Requires permit: removal of more than 25% of canopy, topping or heading cuts on oaks (which causes decline), pruning within the tree protection zone (dripline) during construction, and any work on a designated heritage tree. Permit applications require an ISA-certified arborist report justifying the work and specifying pruning standards (ANSI A300). Work on privately owned trees overhanging a neighbor's property is limited to the portion on the neighbor's side and must not damage the tree (Booska v. Patel). SMUD (Sacramento Municipal Utility District) handles mandatory clearance pruning under utility lines and may trim without owner consent to maintain 10-foot minimum clearance under GO 95. Tree trimming during bird nesting season (Feb 1 – Aug 31) requires nest survey to comply with Migratory Bird Treaty Act and CA Fish & Game Code §3503.
Unpermitted major pruning of protected trees: fines $500-$5,000 depending on tree value (appraised via ISA Trunk Formula Method). Topping of oaks: additional mitigation replanting required. Bird nest destruction: state and federal wildlife violations possible.
