Walkways, driveways, curb cuts and off-street parking should be planned and designed so as to minimize interference with smooth traffic flow, to encourage separation of pedestrian from vehicular traffic, and to be as safe and convenient as is practical. They should not be out of relationship with the design of the proposed buildings and structures on the site, and should not intrude on the privacy of, or conflict with the appearance of neighboring properties. (Ord. 90-5 § 2, 1990; Ord. 181 NS § 1, 1972; prior code § 25-12(g).)
