Walks.
(i) A public walk shall be at least 48 inches wide and shall have a gradient not greater than 5 percent. A walk of maximum or near maximum grade and of considerable length shall have level areas at regular intervals. A walk or driveway shall have a nonslip surface.
(ii) A walk shall be of a continuing common surface and shall not be interrupted by steps or abrupt changes in level.
(iii) Where a walk crosses a walk, a driveway, or a parking lot, they shall blend to a common level. However, the preceding sentence does not require the elimination of those curbs which are a safety feature for the handicapped, particularly the blind.
(iv) An inclined walk shall have a level platform at the top and at the bottom. If a door swings out onto the platform toward the walk, such platform shall be at least 5 feet deep and 5 feet wide. If a door does not swing onto the platform or toward the walk, such platform shall be at least 3 feet deep and 5 feet wide. A platform shall extend at least 1 foot beyond the strike jamb side of any doorway.
