As part of the Memorandum of Agreement (MOA) negotiations, Metro and the City established pre-existing noise levels near the project work sites. The MOA places strict limits on allowable noise levels and identifies potential financial penalties for noise violations. The Independent Compliance Monitor (ICM) is responsible for measuring noise levels and enforcing limits during all construction activities. For more information on the allowable noise levels at the Wilshire/La Cienega Station, visit Article XIV of the Section 1 MOA (page 24). For information regarding allowable noise levels at the Wilshire/Rodeo Station, visit Article XIV of the Section 2 MOA (page 28).

To minimize noise impacts, the contractors have installed fencing and sound walls around all staging areas. Also, noise-monitoring equipment is used and maintained in areas where heavy equipment is in use.
