ENVIRONMENTAL

Illingworth & Rodkin specializes in the assessment and control of environmental noise and is considered one of the leading consulting firms in the West Coast that provide a full range of testing and design services for the abatement of transportation noise. The firm provides its services directly to governmental agencies and private sector clients and acts as a sub-consultant to other environmental and design professionals. A large number of transportation noise studies ranging from environmental impact assessments to developing comprehensive mitigation measures for residential, commercial and other types of existing and proposed developments have been conducted. While most of the work is conducted in Northern California, the firm has completed projects throughout California and the western United States.

Illingworth & Rodkin combines a strong theoretical and a thorough empirical approach to environmental noise studies. Staff has extensive experience with the computer models including TNM, Sound32, LeqV2, and SoundPlan. However, the firm recognizes the computer models' strengths and weaknesses, and emphasis is placed on becoming thoroughly familiar with the various parameters that would affect the noise environment and one's ability to predict future conditions, and conducting thorough and comprehensive measurements to assist in the analysis. Project-level noise measurements are made at least weekly. The firm makes about 200-300 noise measurements per year.
