It shall be the duty of each owner of property located within the city to reconstruct,
maintain and keep in good repair, uniform sidewalks located within the public right-of-way
abutting upon each parcel of his property. Where no sidewalk currently exists, property
owners shall have one (1) year from the passage of this article [Sept. 10, 2001] to
construct sidewalks in compliance with standards as described in section 18-13 of the City Code. Parcels fully developed as of the enactment of this article under
an existing site plan which did not require sidewalks are exempt from the requirements
of this section to construct new sidewalks.
