CB8 Hearing: 04/22/20 (Disapproved)
LPC Hearing: 05/12/20 (Approved with Modifications)

FRIENDS' Testimony:

FRIENDS’ Preservation Committee commends the applicant for listening to the community concerns and altering the proposal to cover only one of the building’s facades, however, we cannot support this proposal. The sign installation is extremely intrusive to the building, with eighty-six perforations alongside the Fifth Avenue, requiring extensive patching to the limestone facade

Finally, the sign will cover an extensive portion of the facade, severely impacting how the mansion is perceived by the community and disrupting the streetscape. While the sign will be only temporary, the damage done to the original masonry of this exceptional building will be permanent and FRIENDS is concerned about the precedent this proposal, if approved, will set.
