CSA staff have been instructors for the FTA’s noise and vibration impact assessment training courses for over 10 years, with the most recent courses in St. Paul, MN in April 2013 and Atlanta, GA in June 2013. The three day course, sponsored by the National Transit Institute, covers the entire noise and vibration guidance manual, including screening, general and detailed assessments for noise and vibration, along with information on mitigation measures and construction noise and vibration. CSA staff have taught over 300 students, including consultants, state DOT and agency staff, and FTA regional and headquarters staff.
CSA worked on the noise and vibration portion of the Merced-Fresno segment of the California High-Speed Rail Project (CA HSR). The CA HSR project is the largest high-speed rail project in the United States. The Merced-Fresno portion was one of two segments applying for ARRA funding, and was the first through the environmental process. The Merced-Fresno segment consulting team was at the forefront of policy and process formation for the entire project. CSA staff worked on the analysis of the noise and vibration data, directed the modeling of the impacts and wrote the noise and vibration technical report and EIS/EIR section. CSA staff also developed the project wide noise and vibration mitigation guidelines, used by the consultant teams on all the project segments.
CSA is currently conducting a noise and vibration assessment of several alternatives for extending MBTA Silver Line service to East Boston and Chelsea. CSA conducted land use surveys and a noise and vibration screening assessment of both exclusive busway and on-street options for the project through one of the most densely populated cities in the country.
CSA conducted a noise assessment for the installation of a sawdust and wood chip separating cyclone at an existing sawmill facility for Hood Industries. The work included conducting both pre- and post-installation noise measurements and assessing the noise levels of the operating cyclone with respect to the MASS DEP noise criteria. CSA also assisted Hood Industries in preparing their permit with the state of Massachusetts for operation of the cyclone at the facility.
CSA is currently conducting a noise and vibration impact assessment for proposed LRT or BRT service from downtown St. Paul east to Woodbury, MN. The work includes conducting existing noise measurements in a heavily traveled corridor paralleling I-94, assessing the impacts of the introduction of LRT or BRT service and preparing the noise and vibration section of the environmental document.
CSA conducted a noise and vibration impact assessment for proposed BRT service from downtown Atlanta to Kennesaw in Cobb County, GA. The work included conducting existing noise measurements in a heavily traveled corridor along I-75 and the Cobb Parkway, assessing the impacts of the introduction of BRT service and preparing the noise and vibration section of the environmental document.
CSA is currently working on the noise and vibration portion of the SW LRT FEIS project. The work includes updating the DEIS noise and vibration
impact assessment, responding to comments on the DEIS, conducting supplemental environmental work and conducting a detailed noise and vibration assessment of the corridor. The project includes options for co-locating the LRT in a freight rail corridor or relocating the freight traffic to another line to accommodate the LRT project.
