California Code, Streets and Highways Code - SHC § 8351

(a) If the public entity owns only an easement for the street, highway, or public service purpose, title to the property previously subject to the easement is thereafter free from the easement for use for street, highway, or public service purposes, but not from any easement for vehicular or nonvehicular trail use that the public entity has previously granted to any other state or local public agency.  If the easement is abandoned by resolution of the state or local public agency that was granted an easement for vehicular or nonvehicular trail use, the title to the property previously subject to the vehicular or nonvehicular easement is thereafter clear of the easement.

(b) If the public entity owns the title, the legislative body may dispose of the property as provided in this chapter.
