1 Combined lot development of two or more lots within the SEFC-1 zone, whether contiguous or non-contiguous, is permitted for the purpose of allocating density for residential and non-residential uses, regardless of any other limitation on floor area by uses as established in this chapter provided that: (a) The aggregate residential and non-residential floor area shall not exceed the matter-of-right maximum height or density of the SEFC-1 zone; (b) A site that is permitted a height of 130 ft. is permitted a maximum non-residential density of 6.5 FAR through combined lot development; and (c) Ground floor area required for ground-floor street-oriented preferred uses may not be transferred to any other lot through combined lot development.
2 A site that has frontage on any portion of New Jersey Avenue, S.E., that is south of and within 322 ft. of M Street, S.E., is permitted a maximum height of 130 ft.
3 Sites fronting on M Street, S.E., east of 4th Street, S.E., are restricted to a height of 90 ft. A building height of 110 ft. maximum is permitted if reviewed and approved by the Zoning Commission pursuant to the procedures of Subtitle K § 211. For the purposes of this review, the Zoning Commission shall consider the relationship of the new building to the Navy Yard to the east and may require graduated height and/or design features because of the building's proximity to the Navy Yard.
