The Legislative Assembly recognizes that significant changes have occurred in the regulation, technology and marketing of telecommunications carriers as defined in ORS § 133.721 over the past decade. It is the intent of the Legislative Assembly in adopting the privilege tax authorized by ORS § 221.505 to 221.515 and 759.219 to respond to these changes by establishing a uniform base for municipal charges for street use by telecommunications carriers.
