Since the passage of the National Environmental Policy Act, environmental issues, in particular noise and land use conflicts, have become a means for an environmentally sensitive public to slow, and sometimes halt, airport development projects.

Landrum & Brown's understanding of noise problems and extensive work in the field contributes significantly to our ability to assist airport operators in the development and implementation of development projects. Our staff has demonstrated expertise in the preparation of more than 100 Part 150 noise compatibility planning studies, noise awareness planning, and land use monitoring programs around the country.

The FAA, our airport clients, and airport neighbors have all recognized Landrum & Brown professionals for the development of innovative techniques in the description of the effects of aircraft noise on communities in environmental assessments.
