Plan Overview
In February 2022, the City Council unanimously adopted a new Specific Plan for East Colorado (ECSP). The plan area encompasses the 1.4-mile section of Colorado Boulevard between Wilson Avenue on the west and Roosevelt Avenue on the east. The plan area also includes Green Street between Wilson and Holliston Avenue, and Allen Avenue between Colorado Boulevard and Corson Street.

The ECSP includes regulations and development standards that would help implement the plan’s vision for vibrant and well-connected mixed-use districts that provide multi-family housing, neighborhood and innovated businesses, and places for locals and students to learn, dine, and shop, all within walking distance to public transit and institutions such as Pasadena City College and Caltech. The ECSP will be implemented over time as new development occurs and as funding becomes available to implement the action items identified in the plan, such as streetscape enhancements that improve multi-modal comfort and safety.
