‘Like fi ngernails on a blackboard’ 
 Whistling luxury condo tower distresses Cobble Hill residents 
 BY KEVIN DUGGAN 
 A luxury condo in Cobble  
 Hill has radiated a shrill whistling  
 sound for months, disrupting  
 life in the quiet brownstone  
 nabe with its piercing  
 noise, according to locals.  
 “It’s like fi ngernails on a  
 blackboard,” said Dorothy Siegel, 
  who lives a block away from  
 the hissing tower. “It hurts your  
 teeth, it’s that kind of sound.” 
 The  15-story  luxury  at  347  
 Henry St. is part of the megadevelopment  
 atop the former  
 Long Island College Hospital  
 campus dubbed River Park,  
 and developer Fortis Property  
 Group plans to hawk the  
 25 apartments at the corner of  
 Amity Street starting at almost  
 $1.3 million for a one-bedroom  
 — but well-heeled potential  
 buyers could be in for a deafening  
 surprise, locals say. 
 “People will be paying for  
 that building and it ends up being  
 like a shrieking horror fest.  
 It  sounds  like  right  before  the  
 knife pierces the shower curtain,” 
  said local Megan McQuillan, 
  referencing the famous  
 4     COURIER LIFE, APRIL 2-8, 2021 
 scene from the 1960s fl ick “Psycho.” 
 The sound coming off the  
 building, dubbed 5 River Park,  
 reverberates for several blocks  
 — as far north as Joralemon  
 Street  in  Brooklyn  Heights,  
 south to Warren Street, and  
 east to Court Street, according  
 to residents.  
 The Cobble Hill Association  
 raised the issue with Fortis at  
 the civic group’s monthly construction  
 task force meetings  
 with the developer, local electeds, 
  and city agencies — and  
 an  acoustic  engineer  hired  by  
 the builder determined that  
 the sound was coming from  
 the building’s balcony railings,  
 which rise for stories above the  
 low-slung nabe and are exposed  
 to gusts coming off the Brooklyn  
 waterfront.  
 The problem has been going  
 on since at least December,  
 according to CHA’s president,  
 who lives a half-block away and  
 said the clamor causes restless  
 nights for him and his family. 
 “It wakes us up,” said  
 Ezana Bocresion. “My wife  
 said  it  sounds  like  a  witch  
 howling at night.” 
 In early March, the developer  
 zip-tied  boards  to  the  
 balustrades, but the stopgap  
 panels soon blew off and were  
 scattered by the fi rst  strong  
 winds within a day or two, according  
 to another CHA board  
 member, who urged the developer  
 to fi nd a long-term fi x.  
 “We just want to make sure  
 that whatever  they do  is  suffi - 
 cient and permanent and if this  
 problem persists post-closings  
 they’re still working on it,”  
 said CHA’s second vice president  
 Amanda Sue Nichols. 
 On Tuesday, a group of local  
 pols sent letters to state Attorney  
 General Letitia James and  
 the city’s Department of Buildings, 
  asking the two offi ces  to  
 not sign off on a condo offering  
 plan and a certifi cate of occupancy  
 — two approvals Fortis  
 needs before they can sell any  
 units — until the whistle stops,  
 according to a local pol. 
 “If they sell the building to  
 condo owners then they’ll wash  
 their hands and walk away,”  
 said Councilmember Brad  
 Lander, whose district covers  
 the area. “Residents of Cobble  
 Hill have been letting Fortis  
 know about this for quite some  
 time and it’s not fi xed. It’s really  
 loud and quite disturbing  
 across a surprisingly large geography.” 
 The  Department  of  Environmental  
 Protection, the city  
 agency in charge of mitigating  
 noise, also plans to send out  
 inspectors  to  take noise readings, 
  according to spokesman  
 Edward Timbers. 
 A spokesperson for Fortis  
 played down the noise as  
 a routine disturbance of new  
 structures, but added that the  
 developer has committed to  
 fi xing the problem.
