In commercial areas, sidewalks may abut the curb.
(c) Pedestrian-way easements ten (10) feet wide may be required by the Planning Commission through the center of blocks to provide circulation or access to schools, playgrounds, shopping, or other community facilities.

(e) Sidewalks and graded areas shall be constructed according to the specifications set forth in these Regulations.
(f) Public sidewalks shall be required for industrial lots, subject to the approval of the Planning Commission.
