How has the contractor worked to reduce noise levels near the work sites?

Metro contractors have implemented several measures to reduce impacts related to noise levels during construction. Some of these include:

Using sound blankets as needed for loud activities and/or equipment.
Adding sound-dampeners to construction equipment, such as cranes.
Modifying construction vehicles to use low impact back-up alarms.
Installing upgraded sound blankets at the La Cienega Yard to increase sound absorption.
Building 20-foot sound walls around all staging yards.

In addition, the following site-specific measures are implemented within Beverly Hills:

For La Cienega Station (Section 1), the ventilation fans at the staging yard are wrapped with sound blankets and fan speeds are reduced when workers are not present in the underground tunnel.
For Rodeo Station (Section 2), a 20-foot sound wall has been installed across N. Canon Dr. near Wilshire Blvd. to protect businesses from construction impacts since late 2019. Silencers have also been installed on the ventilation system to reduce noise levels.

The Independent Compliance Monitor will continue to monitor noise levels and enforce noise threshold limits during all construction activities.
