General Services:
New York City Noise E Designated Site.

Hydro Tech worked with the New York City Mayors Office of Environmental Remediation (NYCOER) to clear Noise “E” Designations assigned to a residential development in the Williamsburg section of Brooklyn following completion of construction. . Upon completion of the development and receipt of the Notice of Satisfaction for hazardous materials, the New York City Department of Environmental Protection (NYCDEP) notified the developer that special windows would be required to mitigate exterior noise. The property owner was faced with a dilemma because construction had already been completed and replacing windows would exceed the project budget.

To solve this issue, Hydro Tech proposed the performance of a Noise Assessment to determine if the existing windows effectively mitigated exterior noise. The assessment was coordinated with the NYCDEP and was performed through a series of noise tests which measured sound in the interior and exterior of the buildings over a 24-hour period. The results of the investigation indicated the existing windows adequately mitigated noise in accordance with the New York City Department of Planning requirements, and as such, a Notice of Satisfaction for Noise was issued for the development.

Hydro Tech subsequently applied the knowledge gained through these noise studies to two (2) newly proposed residential buildings being constructed within the same development. Hydro Tech recommended noise surveys be performed to determine the exterior noise levels and the interior noise levels that would be experienced utilizing the proposed standard project windows. Hydro Tech coordinated all work with the newly formed NYC Office of Environmental Remediation (OER) and performed the noise surveys. The noise surveys confirmed that the proposed standard windows would mitigate sound to levels acceptable to the OER and building plans did not have to be revised to include more expensive windows. Upon completion of the buildings Hydro Tech issued a closure report and a Notice of Satisfaction was issued by the OER.
