Supplemental Environmental Impact Report Notice of Availability

The Metro Gold Line Foothill Extension Phase 2B Project, also known as the Foothill Gold Line from Glendora to Montclair (Project), is undergoing a supplemental environmental review and the public is invited to review the Draft Supplemental Environmental Impact Report (Draft SEIR) and provide comment between September 25, 2020, and November 9, 2020.

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 is proposed for 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 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 previously approved location and footprint. In response to these proposed changes, a SEIR has been prepared 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 previously 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.
