(1) Outdoor advertising signs in existence on May 30, 2007, and lawfully located within commercial or industrial zones in existence on May 30, 2007, and outdoor advertising signs visible from a road or street that is designated as a state highway after May 30, 2007, and lawfully located within a commercial or industrial zone at the time the road or street is designated as a state highway, may remain. Subject to the provisions of ORS 377.700 to 377.844, such signs may be maintained, reconstructed and relocated. However, such signs may not be relocated unless a relocation permit has been issued pursuant to ORS 377.767.

Upon payment of just compensation, the department may remove the outdoor advertising sign. It may not be reconstructed or replaced if destroyed by natural causes and may not be relocated.
