Summary
Santa Ana keeps its street trees on a roughly four-and-a-half-year trimming cycle and requires the city to prune any public tree so its limbs don't block a streetlight or intersection view, keeping a clear space of 14 feet above the street or sidewalk. Topping a public tree is banned as a normal practice, and tree-related decisions can be appealed.
The City of Santa Ana shall maintain the city's urban forest on an average 4½-year trimming cycle based on species, the recommendations of a certified arborist, and the International Society of Arboricultural Tree Pruning Standards. The city shall maintain and prune any public tree with limbs or branches so that branches shall not obstruct the light from any street lamp or obstruct the view of any street intersection so that there shall be a clear space of fourteen (14) feet above the surface of the street or sidewalk.

Full Breakdown
Sec. 33-189, 'Public tree pruning,' provides that the City of Santa Ana shall maintain the city's urban forest on an average 4½-year trimming cycle based on species, the recommendations of a certified arborist, and the International Society of Arboricultural Tree Pruning Standards, and that the city shall maintain and prune any public tree with limbs or branches so that branches shall not obstruct the light from any street lamp or obstruct the view of any street intersection so that there shall be a clear space of fourteen feet above the surface of the street or sidewalk.
The duty sits within an article that also gives the city broad authority under Sec. 33-187 to plant, prune, maintain and remove trees, plants and shrubs within street, alley, avenue, square, parkway and public-ground lines whenever necessary for public safety or to protect the symmetry and aesthetics of public grounds, including removing any tree that's unsafe or injurious to sewers, power lines, gas lines, water lines or other public improvements, or infested with a harmful fungus, insect or pest. Sec. 33-190 separately bars topping, cutting a public tree back to stubs as a routine practice, by any person, firm or city department.
New development must show existing trees to be kept or removed, and any street trees required for the project, on the site plan reviewed under Sec. 33-188. Property owners or others aggrieved by a tree-related finding, notice or action under this article may appeal through the Chapter 3 process (Sec. 33-194).
Violations & Fines
Sec. 33-190 makes it unlawful for any person, firm or city department to top a public tree as a normal practice, and this article carries no separate penalty section, so the citywide general penalty in Sec. 1-8 applies: violating the tree-care provisions is a misdemeanor punishable by up to a $1,000 fine, up to six months in jail, or both, with an administrative citation available as an alternative under Sections 1-21.1 through 1-21.9.
