Membership in the Mitigation Advisory Committee was predetermined by Caltrans. They called for representatives from the cities of Pasadena, Los Angeles, Alhambra, and South Pasadena. Additional representation on the committee was from the Southern California Association of Governments (SCAG), the Los Angeles County Transportation Commission (LACTC), and the National Trust for Historic Preservation.

South Pasadena maintained that the membership was heavily weighted towards freeway proponents, and was not conducive to resolving the dispute.
