The Construction Authority, as the lead agency under the California Environmental Quality Act, certified a Final Environmental Impact Report for the Azusa/Glendora to Montclair Project (Project) 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, a Supplemental EIR (SEIR 1) in 2019 for the phased construction and operation of the project, and SEIR 2 in January 2021 for station area parking modifications. See the Previously Approved Environmental Reviews section below for more information on these environmental reviews. In October 2021, the Construction Authority initiated SEIR 3 to review potential project modifications in the city of San Dimas. See Environmental Reviews Currently Underway for more information on this current environmental review.

BACKGROUND: The Construction Authority will evaluate potential Project Modifications in the city of San Dimas. On June 17, 2021, the City of San Dimas in cooperation with the Construction Authority approved a binding letter of intent to consider relocating the San Dimas Station parking facility to property owned by the City. The city prefers not to displace the City Yard that is located within the currently approved parking facility location (SEIR 2 certified in January 2021) and expressed a desire instead to locate parking for the Project on an existing parking lot west of the future San Dimas Station. The proposed site is currently used as the San Dimas Park & Ride Lot for Foothill Transit and located south of the project right-of-way (ROW) between San Dimas Ave. and Monte Vista Ave.

For this SEIR 3, the Construction Authority is considering relocation of the parking facility in the City of San Dimas from the approved location in SEIR 2 to this requested location (see map below). The proposed new parking location would be redeveloped to accommodate the same number of parking spaces as planned at the currently approved parking location. The Construction Authority also proposes new roadway and pedestrian access changes to the San Dimas Station.

No modifications are proposed for the parking facilities at the Glendora, La Verne, Pomona, Claremont, and Montclair Stations.
