(a) Requirement of Sunlight Access on Certain Streets. In C-3 Districts, in order to maintain direct sunlight on public sidewalks in certain downtown areas during critical periods of use, new structures and additions to existing structures on parcels which abut on the side of a street identified below shall be required to avoid penetration of a sun access plane defined by an angle sloping away from the street above a stipulated height at the property line abutting the street, as follows:

(b) Exception. An exception to the requirements of Subsection (a) may be granted in the manner provided in Section 309 of this Code in cases where (i) the penetration of the plane does not create shadow because of the shadow already cast by other buildings, or (ii) the shadow created by the penetration of the plane is deemed insignificant because of the limited extent or duration of the shadow or because of the limited public use of the shadowed space.
(c) Shadows on Other Streets. New buildings and additions to existing buildings shall be shaped, if it can be done without creating an unattractive design and without unduly restricting the development potential of the site in question, so as to reduce substantial shadow impacts on public sidewalks in the C-3 Districts other than those protected by Subsection (a). Determinations made under this Subsection shall be made in accordance with the provisions of Section 309.
