Project Experience: System-wide Abatement Assessment and Abatement Design, Texas

The Challenge

The North Texas Tollway Authority (NTTA) needed a system-wide noise study along the Dallas North Tollway.

The Strategy

HMMH conducted a comprehensive noise analysis that included:

  • Long-term and short-term noise measurements
  • Preparation of study corridor mapping
  • Detailed land-use inventory
  • Noise-abatement policy development
  • Eligibility evaluation for all noise-sensitive areas
  • Priority ranking of assessment areas
  • Detailed acoustical design of noise barriers for 25 areas
  • Public hearings and community workshops

Wendy Lopez & Associates, Inc. supported HMMH by providing mapping, land-use information, public relations support, barrier materials unit costing, and local coordination.

The Solution

The NTTA is implementing the noise abatement program, and is also evaluating a pavement overlay to further reduce noise emissions from the Dallas North Tollway.
