Definition of Road Frontage and Ribbon Development
For policy purposes, a road frontage includes footpaths and private lanes. A ribbon does not require continuous service, uniform building lines, or individual accesses; staggered or angled buildings with gaps can still constitute ribbon development if visually linked.
For the purposes of this policy a road frontage includes a footpath or private lane. A 'ribbon' does not necessarily have to be served by individual accesses nor have a continuous or uniform building line. Buildings sited back, staggered or at angles and with gaps between them can still represent ribbon development, if they have a common frontage or they are visually linked.
