The Project lies in the City of Irvine (or City). The main Project Footprint is located on a 21.3-acre OCTA-owned parcel in the City, adjacent to Marine Way and OCTA Metrolink Tracks, between mileposts 183.50 and 184.00. Regional vehicle access to the Project Site is from I-5 at Sand Canyon Avenue. Local vehicle access is via Marine Way to Ridge Valley.
The Project consists of various project elements that can be separated into two phases, based on their purpose and timing of construction and implementation. Phase 1 consists of developing facilities needed for train storage consisting of the Service and Inspection (S&I) Facility tracks, train wash track, storage tracks, set-out track(s), yard lead tracks, transportation building, and employee parking. Phase 2 includes construction of the maintenance building and associated tracks, as well as the conversion of the west lead track into a drill track, and the construction of a second run-around track within the mainline track corridor. Additionally, a new two-lane access road would be constructed to provide access to the maintenance facility and would be within the OCTA Project and City right-of-way.
