In R3, R4 or R5 Districts, the Commission may modify the height and setback regulations set forth in Section 23-631 and paragraph (b) of Section 78-31, on the periphery of such large-scale residential development, for the purposes of introducing variety, providing a transition in neighborhood scale between the large-scale residential development and surrounding buildings, preserving natural features or view corridors, or improving the access of light and air;
