(3) “Wireless telecommunications colocation facility” means a wireless telecommunications facility that includes colocation facilities.

(e) The Legislature finds and declares that a colocation facility, as defined in this section, has a significant economic impact in California and is not a municipal affair as that term is used in Section 5 of Article XI of the California Constitution, but is a matter of statewide concern.
