HUD Noise Assessment

Client: Leewood Real Estate Group, LLC

Project Location: The Whittaker at Mill Hill, Trenton, NJ

Overview:

  • Conducted a HUD Noise Assessment

  • Sources included rail lines, major roadways and airports

  • A composite wall-window sound rating was calculated for the exterior facade of the buildings

  • Project was determined to be acceptable based on HUD criteria.

TNC conducted a U.S. Housing and Urban Development (HUD) Noise Assessment for the proposed residential property, The Whittaker at Mill Hill which consists of 40 units in two, four-story buildings. The objective of the noise assessment is to determine the acceptability of the noise impacts associated from nearby airports, roadways, and railways, based on HUD procedures and criteria.

 

The primary noise sources are US Route #1 and the Northeast Corridor Rail line which are within 330 feet and 395 feet, respectively, of the closest property line of the proposed project.  The River Line (a light rail line) at approximately 1000 feet from the project site was considered, but as expected, had no significant impact on the calculated noise level. 

Based on a determination of the composite wall-window sound rating of 32 dB, all 40 units were determined to be acceptable based on HUD criteria .

E-Designation - NYC

Client: Elevation Holdings, LLC

Project Location: Brooklyn, NY

Overview:

  • Developed a Noise Monitoring Protocol for submission to NYC Office of Environmental Remediation (OER)

  • Conducted Site-specific monitoring according to OER requirements to determine if a lower OITC rating would be acceptable

  • Calculated the composite wall-window sound rating for the exterior facade of the buildings based on monitoring results

  • OER accepted a lower OITC rating for building facades.

The client was constructing an eight-story multi-unit residential building which had an E-designation which required a wall/window attenuation (OITC rating) of 35 dBA based on an assigned L10 noise level of 78.4 dBA.

Site-specific sound level data were collected over a 24-hour period at two locations on the property.

An maximum hourly L10 of 74.2 dBA was measured during the site-specific monitoring. A request was made to OER and approved to modify  the E-designation for this parcel to an OITC rating of 31 dBA resulting in a substantial reduction in cost for windows while maintaining an acceptable interior noise level.
