Featured Project

Meridian Crossing Apartments

Client Name: Reybold Venture Group

Project Location:
Bear, Delaware

Highlights:

  • Detailed FHA Noise Study
  • Sound Mitigation Recommendations

Lewis S. Goodfriend & Associates completed an acoustical analysis for ten apartment buildings to satisfy the Department of Housing and Urban Development (DHUD) FHA mortgage application requirements. Nearby sound sources included aircraft from a nearby civilian and military airport, and an adjacent Norfolk Southern freight train route. While most of the buildings were found to have an acceptable acoustical environment by DHUD guidelines, a few buildings adjacent to the railroad track were found to be normally unacceptable. Recommendations were made to improve the sound isolation provided by the facades of these building, resulting in an acceptable acoustical environment. LSG&As acoustical report and supporting documentation helped to get all ten apartment buildings approved for FHA mortgage eligibility.
