Purple Line Extension Section 2 Construction Update Webinar May 21, 2020

COVID-19 Compliance > As part of the Federal government’s Coronavirus Guidance for America, transportation infrastructure is considered an “Essential Critical Infrastructure.” > Additionally, transit capital projects are not subject to the State of California’s Stay at Home order, therefore Metro construction projects continue to progress. Updated personal protective equipment (PPE) 3

COVID-19 Compliance > Construction activities continue to progress on all active Metro projects, including the Crenshaw/LAX, Purple Line Extension and Regional Connector Transit Projects. > Due to reduced traffic conditions during the Stay at Home orders, local jurisdictions are allowing the Agency to work through “peak hours” on a case by case basis. > Metro’s contractors are following safety precautions during the pandemic, including implementing social distancing when applicable and the use of masks and other PPE. 4

Oil Well Investigation and Discovery at Beverly Hills High School (BHHS) 29

Oil Well Investigation and Research During community outreach meetings in 2018, we outlined plans for investigating underground wells at the BHHS. As part of the EIS/EIR phase, the Project Team:  Reviewed historic maps and photographs,  Researched geological data bases,  Obtained historic well records and consulted petroleum industry experts 30

Potential for Encountering Abandoned Oil Wells during Tunneling What has been done?  Other historic maps with oil well locations have been obtained and evaluated  The subway has been aligned to avoid the documented oil well locations  Magnetometer surveys have been performed along the alignment to screen for the presence of oil well casing 31
