Cal. Pub. Util. Code § 132435
The authority shall enter into a memorandum of understanding with the LACMTA that shall specifically address the ability of the LACMTA to review any significant changes in the scope of the design or construction, or both design and construction, of the project. For purposes of this section, the term "significant change" means any change of mode or technology, or any other substantive change that affects the connectivity and operation of the project as part of the overall transit system operated by the LACMTA, or any combination of those things. Design and construction of a light rail project that is consistent with the current scope of the project shall not be deemed to be a significant change in the scope of the project and shall not require concurrence by the LACMTA.
