  • 14. Medlin & Associates, Inc. Acoustical Consultants Caltrans Traffic & Transportation Noise Traffic Noise, Community Noise, Pavement Noise, Sound Wall Assessment State Route 210, Cities of Claremont and LaVerne California Medlin provided project oversight, technical direction and specialized noise consulting services for this study of highway noise impacts on the communities. The study was commissioned by the Cities following the opening of State Route 210, after hundreds of community noise complaints were received along this 12 mile corridor. The level of public involvement warranted an innovative approach to conducting a traffic noise study. On-site noise measurements and a focus on evaluation of further mitigation options were favored over repeating a computer traffic noise model. Specialized noise services included: • Concrete pavement vs. quieter pavement noises were evaluated on a spectral basis • Sound wall barrier effectiveness was measured on a spectral basis • Holes in sound walls were evaluated to determine if gaps were a contributing factor • GPS was used in conjunction with corridor noise measurements • Exterior-to-interior noise levels were evaluated Our findings concluded that excessive noise levels existed in the project area which exceeded FHWA and Caltrans Noise Abatement Criteria. Benefit: Traffic noise impacts on communities cannot be underestimated. Medlin recommendations included repavement with a quieter pavement to provide further noise reductions which will provide benefit to the entire community. P.O.
