| Enlivening Ground Floor Uses |

Ground Floor Uses - View a larger image |
To ensure a mix of commercial and retail uses as already permitted by the underlying zoning, the proposal would require that the first 30 feet of the entire ground floor frontage be developed with certain permitted commercial or community facility, non-residential uses. Of the ground floor frontage of a lot, at least 50% must be occupied by retail uses. The remaining frontage of the lot (but not more than 50%) may be occupied by uses otherwise permitted in the C2-4 zoning district, with the exception of public parking garages, as well as lobby spaces and parking entrances where applicable. This flexibility in permitting a range of uses will encourage the development of a varied, active streetscape.
While parking and residential uses remain desirable and would continue to be permitted, these uses would be accommodated elsewhere in the building as otherwise permitted by zoning or beyond the first 30 feet of the building on the ground floor. Residential lobby sizes would be limited to 25’ at most to ensure that the maximum feasible ground floor space be occupied by shops and offices that serve the neighborhood and its new residents.

| Sidewalk Continuity/Curb Cuts |
To ensure that cars do not overshadow the pedestrian experience, curb cuts serving new buildings would generally be limited to the side streets. This would minimize interruptions to the sidewalk and streetwall and assure that Fourth Avenue developed and evolved with an improved pedestrian environment. A curb cut would only be permitted on Fourth Avenue if it serves an interior zoning lot which does not have access to a side street AND has a lot width along Fourth Avenue greater than 60’.

| Streetscape Design/Transparency |
|
To ensure an interactive and social space along 4th Avenue, all uses fronting on Fourth Avenue, including lobbies, must adhere to a minimum level of streetwall transparency of 50% measured between 2’ and 12’. Shops and uses with glass storefronts allow pedestrians to look at activities inside from the sidewalk. Blank streetwalls necessary for building elements such as columns or fire doors could not exceed 10’ in width. |
