The maximum height of a building or other structure before setback shall be as specified on Map 3 (Minimum and Maximum Base Heights) in the Appendix to this Chapter. When a building fronts on two intersecting streets for which different maximum base heights apply, the higher base height may wrap around to the street with the lower base height for a distance of up to 100 feet. At a height not lower than the minimum base height, and not higher than the maximum base height, a setback shall be provided in accordance with the provisions of Section 23-433 (Standard setback regulations).
