The depth of such initial setback distance from the boundary of a shore public walkway may be reduced to five feet, provided that at least 40 percent of the width of each story required to be set back above the minimum base height is set back no less than 10 feet from the boundary of the shore public walkway.
(b) Measurement of height
The provisions of paragraph (a)(3) of Section 62-341 shall apply, except for the purpose of this Section, base plane shall refer to an elevation of 16.8 feet above Richmond Datum.

(e) Maximum building height and tower size
The maximum residential tower size provisions of paragraph (c)(4) of Section 62-341 shall not apply.

Buildings with tower portions fronting on Edgewater Street shall not exceed a height of 120 feet above the base plane or 12 stories, whichever is less. The height of any other building with tower portions shall not exceed a height of 110 feet above the base plane, or 11 stories, whichever is less. Each story within a tower portion of a building shall not exceed a gross area of 10,000 square feet up to a height of 90 feet or nine stories, whichever is less, and each story above a height of 90 feet or nine stories, whichever is less, shall not exceed a gross area of 8,100 square feet.

In no event shall a street wall extend along a shore public walkway for a distance greater than 130 feet without providing such a recess. Furthermore, above the height of the second story, such street walls shall provide at least one additional recess with a minimum depth of five feet and a minimum width or, where applicable, an aggregate width, of at least 40 feet.

A lobby to a commercial or community facility use shall have a minimum width of 20 feet. Transparent glazing materials shall occupy at least 50 percent of the surface area of the street wall of the lobby, measured between a height of two feet above the level of the adjoining grade and a height 12 feet above the level of the first finished floor.
