(a) Public Sidewalks.
(1) New public sidewalks, constructed to meet Centerburg standards, shall be required along the street frontage of any lot being developed when the following conditions exist:
A. The development includes new construction on a vacant lot or complete redevelopment of an existing principal building (e.g., the principal building is torn down and replaced);
B. There is no public sidewalk along one or more of the public street rights-of- way adjacent to the lot; and
C. There is adequate existing right-of-way for the public sidewalk.
(2) New sidewalks shall also be required when proposed sidewalks or paths are identified in the Knox County Active Transportation Plan for the lot or lots that are part of the applicable development or application.
(b) Internal Pedestrian Access.
(1) Where a sidewalk exists in a public right-of-way adjacent to the site, or is required to be constructed as part of the development approval, , a paved pedestrian connection shall be constructed from the sidewalk to the entrance of the building.
(2) The pedestrian connection shall have a minimum width of five feet.
(3) All pedestrian walkways located within a site (internal pedestrian circulation) shall be physically separated from the drive lanes and driveways. Additionally, all sidewalks and crosswalks shall be constructed of an impervious surface and shall be visually distinct from the driving surface by use of pavers, color, bricks, scored concrete, or other material approved by the Zoning Administrator or Planning Commission, as applicable. See Figure 1115-E.
