Certified 2020 PEIR

The Southern California Association of Governments (SCAG), as Lead Agency, prepared a Program Environmental Impact Report (PEIR) (SCH#2019011061) in accordance with the California Environmental Quality Act (CEQA) for Connect SoCal 2020 (2020-2045 Regional Transportation Plan/Sustainable Communities Strategy). The PEIR serves as a programmatic document that conducts a region-wide assessment of potential significant environmental effects of Connect SoCal 2020.

The Connect SoCal 2020 Draft PEIR was released Dec. 9, 2019, for a 45-day public review and comment period ending Jan. 24, 2020. A public workshop took place at SCAG’s main office located at 900 Wilshire Blvd., Suite 1700, Los Angeles, CA 90017, on Thursday, Jan. 9, 2020, from 2 to 3:30 p.m.

Following a cooperative and comprehensive planning process with stakeholders, SCAG incorporated public input into the Connect SoCal 2020 Final PEIR through corrections and additions, and responses to all comments. The Final PEIR is a continuation of the Draft PEIR and is comprised of the following: Complete Connect SoCal 2020 Draft PEIR; Chapter 8.0, Introduction; Chapter 9.0, Response to Comments; and Chapter 10.0, Corrections and Additions, and Appendices.

Errata to the Final Connect SoCal PEIR

Resolution

Connect SoCal 2020 PEIR Addendum #1

In accordance with the California Environmental Quality Act (CEQA), SCAG has prepared the Connect SoCal 2020 PEIR Addendum #1 to address technical refinements to the growth forecast in relation to entitlements and to address two comment letters from the Center of Biological Diversity (CBD) on May 1, 2020 and May 6, 2020. Upon evaluation, SCAG found that technical refinements resulted in minimal impacts to Connect SoCal’s performance results and Connect SoCal would continue to achieve federal air quality conformity and meet the State’s per-capita GHG reduction targets for 2020 and 2035.

The Connect SoCal 2020 PEIR Addendum #1 was approved by the SCAG Regional Council on September 3, 2020.

Resolution

Connect SoCal 2020 PEIR Addendum #2

In accordance with the California Environmental Quality Act (CEQA), SCAG has prepared Addendum #2 to the Connect SoCal 2020 PEIR, which analyzes the changes documented in the Final Connect SoCal Amendment #1. Upon evaluation, SCAG finds that the proposed changes would not result in a substantial change to the region-wide impacts when compared to the certified PEIR with Addendum #1. SCAG staff also finds that the projects identified in Connect SoCal Amendment #1 are programmatically consistent with the analysis, mitigation measures, and Findings of Fact contained in the previously certified PEIR with Addendum #1. The amended Connect SoCal would continue to achieve federal transportation conformity and meet the State’s per-capita GHG reduction targets for 2035.

Addendum #2 to the Connect SoCal 2020 PEIR was approved by the SCAG Regional Council on November 4, 2021.
