Los Angeles County Metropolitan Transportation Authority in California, USA has launched an environmental review process for Sepulveda transit corridor concession. Apart from environmental concerns, the process will also include various tasks such as project scoping, an extended formal public comment period, and accepting public input via virtual public meetings. 

The environmental process aims to study the following six alternatives and their feasibility :

1. Automated monorail that would be entirely aerial along the 405 corridor and the Metrolink Ventura County Line railroad tracks with an electric bus shuttle to UCLA.
2. Automated monorail with aerial alignment along the 405 corridor and Metrolink Ventura County Line railroad tracks with an aerial automated people mover connection to UCLA.
3. Automated monorail with aerial segment along the 405 corridor, an underground segment between Wilshire and Getty Center, then entirely aerial along the 405 and Van Nuys Metrolink Line railroad tracks.
4. Heavy rail with underground segment south of Ventura Boulevard and aerial alignment generally along Sepulveda Boulevard in the San Fernando Valley.
5. Heavy rail with underground alignment including along Sepulveda Boulevard in the San Fernando Valley.
6. Heavy rail that would be entirely underground including along Van Nuys Boulevard in the San Fernando Valley and with a southern terminus station on Bundy Drive on the Westside
