The Residential Noise Insulation Program (RNIP) has been implemented under Phase I to mitigate project noise at eligible residences in the project corridor where typical mitigation measures, such as sound wall construction, did not fully reduce noise levels above the ground floor of multi-level buildings.

Federal and state environmental documents for the project identified a number of residences as potentially eligible for RNIP within Phase I of BART Silicon Valley Extension. Noise levels inside these residences or multiple units were estimated as part of the VTA’s BART Silicon Valley Berryessa Extension noise studies when the Environmental Documents were prepared. Follow-up testing and assessments were performed at all potentially eligible properties to determine which of the RNIP improvements were installed. Each residence found eligible received RNIP improvements based on the estimated noise levels, such as acoustical glass, triple pane windows, solid core doors, and/or weather-stripping.
