Noise

Urban Crossroads provides the full spectrum of environmental noise measurement and analysis expertise. This may include a preliminary noise study to establish the barrier height requirements for tentative tract map approval, detailed building assembly requirements as part of a final noise study to satisfy the interior noise requirements, project operational stationary-source noise levels and potential short-term construction noise impacts. In addition, our noise group maintains a strong technical background in the application and development of noise prediction models.

Urban Crossroads, Inc. provides both short and long-term noise level measurements to assess the existing noise environment and effectively analyze the contributions of a given project on future ambient noise levels. Noise level measurements provide an understanding of existing conditions as they relate to local regulations and the noise-sensitive land uses in a given study area. Our staff is experienced with collecting noise level measurements for a variety of projects from residential homes to commercial and warehouse developments, and use equipment which meets the latest American National Standards Institute (ANSI) standard specifications for sound level meters.

Urban Crossroads provides traffic noise impact analysis services to support tentative tract map approval and environmental documents based on CEQA requirements. Through the use of Federal Highway Administration (FHWA) Traffic Noise Prediction Model programs and procedures, our staff evaluates the existing noise environment and projects future noise impacts related to both the off-site traffic noise levels from a project, and the on-site traffic noise levels to a project. Based on detailed research and analysis, we provide thorough recommendations on exterior and interior noise level mitigation measures to satisfy applicable Federal, State, and Local transportation noise standards.

Through the use of reference noise level measurements, Urban Crossroads, Inc. analyzes the impacts of operational stationary-source noise impacts on future noise environments. Our staff maintains reference noise levels on a variety of noise sources and can provide additional measurements to meet the needs of our clients. Reference noise level measurements allow our staff to forecast the future noise levels of commercial, industrial, and warehouse projects, amongst others, and the potential impacts to noise-sensitive land uses in their vicinity. Our analysis services can be utilized for both day and night operations, as well as projects with multiple potential noise sources.

Urban Crossroads, Inc. has prepared detailed studies for construction noise to meet a variety of local regulations, and addresses each project with the approach appropriate to meet the applicable noise standards. Our staff analyzes construction noise levels in a given study area by examining the existing environment and determining the best approach to reduce the noise levels from heavy machinery to nearby noise-sensitive land uses. Our experience includes the preparation of construction noise mitigation and monitoring plans, temporary construction barriers, and equipment staging analysis services to reduce temporary noise level increases to satisfactory levels.
