Carson FAQ
Does Carson designate specific 'heritage' or 'specimen' trees?
No — Carson does not maintain a named heritage-tree list in its Municipal Code. All parkway and right-of-way trees are equally protected under Article 3 Chapter 9, and a large mature tree's value under the CTLA Guide for Plant Appraisal can far exceed $1,000, so the penalty scales with the tree.
Can a developer remove a mature tree during construction?
If the tree is in the parkway or city right-of-way, the developer must obtain Public Works approval under Chapter 9 and follow any replacement direction from the Public Works Division. For trees on private property, no city-wide private-tree permit applies, but check zoning landscape conditions of approval under CMC Article IX.
