The Construction Authority, as the lead agency under the California Environmental Quality Act, certified a Final Environmental Impact Report in 2013 (2013 FEIR). Following the certification of the 2013 FEIR, the Construction Authority identified a number of refinements to the Project. The Construction Authority has since approved four addenda to the 2013 FEIR, and a Supplemental EIR (SEIR) in 2019. The Construction Authority has prepared the current Draft Supplemental Environmental Impact Report in response to proposed Project Modifications. Below, in order of most current to oldest, are links to all environmental review documents for the Project. Starting on top is the Draft Supplemental Environmental Impact Report currently under public review; with links below to the 2013 FEIR, the four subsequent addenda and the 2019 SEIR.


Environmental Reviews Currently Underway


The Construction Authority has prepared a Draft Supplemental Environmental Impact Report (Draft SEIR) for the Metro Gold Line Foothill Extension Phase 2B Project (Project), also known as the Foothill Gold Line light rail project from Glendora to Montclair. The Draft SEIR evaluates the potential for environmental impacts resulting from potential modifications to the Project and provides mitigation measures where required.

The Construction Authority is considering modifications to the Project to construct surface parking lots (instead of enclosed parking structures, as previously approved) at the Glendora, San Dimas, La Verne, and Pomona Stations. Constructing surface lots would reduce the number of available parking spaces. To accommodate the reconfigured parking conditions, the Authority proposes increasing the property size of the Glendora and San Dimas Station parking facilities, and a property location change at the Pomona Station parking facility. No changes are proposed for the location or property size of the parking facility at the La Verne Station. Changed vehicle and pedestrian access and new or relocated turnabouts are also proposed. Additional changes are proposed by the Authority that will result in a reduction of parking at the Claremont Station. Two Claremont options will be considered wherein reduced parking is accommodated either fully in a parking structure or via parking surface lot combined with leasing of additional parking spaces from available locations within 1/4 mile of the Claremont Station. Provision for parking structure or surface lot at the Claremont Station will occur within the same location and footprint identified and cleared in Addendum 2 to the 2013 FEIR. In response to these proposed changes, the Authority has prepared a SEIR to evaluate the potential for significant impacts that may result from the potential changes at the five stations. Multiple scenarios that include interim and full build terminus station conditions have been evaluated.

The proposed changes do not alter the scope of the Project as approved by the Construction Authority. The Draft SEIR has concluded construction of the Project Modifications would not have new or more severe significant impacts or require new mitigation measures.

The public review and comment period for the Draft SEIR started on September 25, 2020 and runs through November 9, 2020. For information on how to comment on the Draft SEIR during the comment period, read details below:
