Generators adjacent to perimeter fencing across from residences, and the absence of barriers to shield the residences from the noise they generate, appear to violate both the spirit and the letter of the Amended Memorandum of Environmental Commitments. The generators are apparently being used to facilitate construction of the Carlton Avenue Bridge.
They are situated directly across the street from residences on the north sidewalk of Pacific Street at the location of the Carlton Avenue Bridge. They are in a highly visible location close to the construction offices and along the walking route between the construction offices and the arena construction site.
A recent incident report declaims, "Their generator is making me crazy !!!!" It asks, "Is there any way we can have them "plug" their damn equipment in instead of using the damn generator ALL DAY EVERYDAY?!?!!? It is really starting to drive me nuts!"
A resident with a decibel reader registered 98 decibel level outdoors in the vicinity of one generator Saturday, December 17th at 6 pm. According to the Guide to the NYC noise code, a train has a decibel level of 100dB(A) and a lawnmower has a decibel level of 85 to 90 dB(A). The guide explains a decibel is a logarithmic unit, "which means that a noise measuring 30 decibels is actually 10 times louder than a noise that registering at 20 decibels." A measurement of 45 dB is recommended indoors and should not exceed 65 dB. Outdoor walls and windows are anticipated to reduce noise levels by 15 dB. Residential units are located roughly 50 feet from the location of the generators.
The Memorandum states that contractors will situate "noisier equipment, such as generators, cranes, tractor trailers, concrete pumps, concrete trucks and dump trucks at locations that are removed from sensitive receptor locations and are shielded from sensitive receptor locations wherever feasible." If not feasible, another step contractors should utilize when practicable are "noise curtains and equipment enclosures . . . to provide shielding from significant noise-generating equipment to sensitive receptor locations."
Although the Memorandum specifies a "minimum 8 foot height perimeter barrier (constructed of 3/4 thick plywood), with a 16 foot hight barrier (of 3/4" thick plywood) adjacent to sensitive locations, including locations along Pacific Street, Dean Street, and Flatbush Avenue opposite residences," there are no barriers of that description installed in this location. The generators are separated from residences by a chain link fence that does not shield noise.
According to nearby residents, three generators of different types have been placed in this location. We have attached photos of the generators to a complaint filed by a resident.
Pacific Street and Carlton Avenue is only one of two locations a generator is placed near a perimeter fence across from residences inside the project footprint. A generator has been located on block 1129 on Dean Street for approximately a year. Like the Pacific Street generator, it is only protected from residences by a chain link fence.
