Summary
In unincorporated Santa Cruz County, routine trimming of trees on your own property is generally allowed without a permit. But in the Coastal Zone, cutting more than one-third of a 'significant tree's' foliage requires a Significant Tree Removal permit (SCCC 16.34), and heavy trimming inside a riparian corridor or sensitive habitat may need approval (SCCC 16.30 / 16.32).
Per County Code section 16.34.030, a 'significant tree' shall include any tree, sprout clump, or group of trees, as follows: Within the Urban Services Line or Rural Services Line, any tree which is equal to or greater than 20 inches d.b.h. (approximately 5 feet in circumference); any sprout clump of five or more stems each of which is greater than 12 inches d.b.h.; or any group consisting of five or more trees on one parcel, each of which is greater than 12 inches d.b.h.
