21-1.01   Violation to Place or Erect Obstructions on City Property.
   a.   It shall be a civil violation as set out in Chapter 27 of this Code for any person to erect or place or cause to be erected or placed any building, sign, fence, brick mailbox or column on any city street, alley, sidewalk, right-of-way or any other real property owned or occupied by the City. Other obstructions, including but not limited to large rocks or boulders, posts, stakes and landscape that are deemed a safety hazard to the public shall also be prohibited, with the exception of public utility infrastructure.
   b.   Any structure that exists within right-of-way as of September 1, 2012 may remain, but may not be enlarged, moved or structurally altered in a way that increases its nonconformity. The Public Works Director or designee shall have the authority to remove the structures should they be deemed an immediate safety concern or impede any public improvement project of the City’s streets and infrastructure. Voluntary demolition of a nonconforming structure nullifies its nonconforming rights. If involuntarily destroyed or removed, the nonconforming structure shall retain its nonconforming rights for a period of one year. Failure to re-establish the structure within one (1) year nullifies the nonconforming rights.
   c.    No structure, sign, fence or vegetation shall be permitted to obscure the vision of the traveling public at any street, alley or driveway intersection as determined by the Public Works Director or designee.
   d.   Notwithstanding the provisions hereinabove, signs designating entrances to subdivisions may be constructed upon city rights-of-way, provided that prior to the construction, plans and specifications for the construction of the sign are approved in writing by the Planning and Design Division of the Department of Public Works through a right-of-way work permit.
