When any encroachment authorized hereunder is found to be in conflict with existing or proposed facilities or improvements owned, maintained, or operated by the City, such encroachment shall, upon written demand of the Assistant City Manager for Public Works, be relocated in such a way as to eliminate the conflict, said relocation to be at the sole expense of the permittee. Should the permittee fail to comply with said written demand within a reasonable period of time, the City may cause such relocation of the encroachment at the expense of the permittee; provided, however, that this section shall become inoperative when any right-of-way shall become a freeway and thus cease to be used for the usual street purposes. Provided, further, that this section shall not apply to any public utility possessing a franchise from the City, which franchise, either by express provision or by statute, imposes a relocation obligation upon said public utility. (Ord. 5514-NS § 1, 1983)
