Under the California Environmental Quality Act (CEQA), public agencies are charged with the duty to avoid or substantially lessen significant environmental impacts of a project where feasible. This process is undertaken through an Environmental Impact Report (EIR), an assessment that identifies any potentially significant impacts of a proposed project on the environment. The EIR indicates the manner in which those significant impacts can be avoided or significantly lessened; identifies any significant and unavoidable adverse impacts that cannot be mitigated; and identifies reasonable and feasible alternatives to the proposed project that would eliminate any significant adverse environmental impacts or reduce the impacts to a less-than significant level.


Environmental Reviews Currently Underway


The Construction Authority has initiated the environmental review of potential Project Modifications to the Glendora to Montclair project. To learn about the potential Project Modifications and the Supplemental Environmental Impact Report to review the environmental impact of those modifications, please review:

Potential Project Modifications to Be Evaluated:

The Construction Authority will evaluate potential parking changes at the Glendora, San Dimas, La Verne, Pomona and Claremont Stations. The Authority previously approved parking structures at these stations. As a result of Project refinements and revised Metro parking provision guidance resulting from a parking study completed by Metro, the Authority is now considering whether a change to surface parking lots for the Glendora, San Dimas, La Verne and Pomona locations as well as either a parking structure at Claremont or a parking lot combined with leased parking space at Claremont is warranted. This would reduce the total number of available parking spaces at the various stations. At some of these locations, the potential change from a structure to a surface lot would result in minor changes related to the configuration of vehicle and pedestrian access. New or modified parking facility locations are being evaluated in Glendora, San Dimas and Pomona. The potential Project Modifications also entail scenarios that include interim and full build terminus station conditions associated with phased construction of the project as previously analyzed in the 2019 Supplemental EIR.

Submitting Scoping Comments

If you want to submit comments on the potential Project Modifications to help frame issues to be addressed in the Supplemental Environmental Impact Report, please submit your comments no later than July 8, 2020 to the following:

Final Supplemental Environmental Impact Report: Evaluating Phased Construction and Operation of the Project – APU/Citrus College Station to Pomona Station and Minor Alignment Adjustments in Glendora (June 2019)

In December 2018, the Construction Authority initiated the preparation of a Supplemental Environmental Impact Report (SEIR) to evaluate the environmental impacts associated with proposed Modifications to the existing approved Glendora to Montclair Project (2013 FEIR as addended). The Draft SEIR was published on March 22, 2019 for a 45-day review and comment period, which included a public hearing/meeting on April 16, 2019. The Final SEIR was published (see below) by the Construction Authority in June 2019, and was approved and certified by the Construction Authority board of directors in July 2019.
