780.12 NON-CONFORMING STRUCTURES OR USES IN RIPARIAN AND WETLAND SETBACKS.
   (a)   A non-conforming use within a riparian and wetland setback which is in existence at the time of passage of this regulation, and which is not otherwise permitted under these regulations, may be continued. However, the use shall not be changed or enlarged unless it is changed to a use permitted under these regulations.
   (b)   A non-conforming structure within a riparian and wetland setback which is in existence at the time of passage of this regulation, and which is not otherwise permitted under these regulations, may be continued. However, the existing building footprint or roofline may not be expanded or enlarged in such a way that would move the structure closer to the stream or wetland.
   (c)   A non-conforming structure or use or deteriorated structure within a riparian and wetland setback which is in existence at the time of passage of this regulation, and which is discontinued, terminated, or abandoned for a period of six months or more, may not be revived, restored, or re-established. Exempted from this section shall be housing stock, seasonal structures or uses that have not been condemned through the nuisance abatement ordinance.
   (d)   A non-conforming structure or use that is discontinued may be resumed any time within six months from such discontinuance but not thereafter. No change or resumption shall be permitted that is more detrimental to riparian and wetland setbacks, as measured against the intent and objectives of these regulations as determined by the City, than the existing or former non-conforming structure or use.
