SUMMARY Over several years and leading up to City incorporation, land development and traffic growth changed the Mulholland Highway corridor from its original rural character. In 1997 the City of Calabasas completed the Mulholland Highway Master Plan document. The Master Plan identified corridor and community issues, and provided direction to help the City improve the traffic operations and landscaping along Mulholland Highway in the future. In 2002 the City initiated an effort to update the 1997 document because of development proposals, approval of a new middle school and increased community interest in the corridor. This Master Plan for Capital Improvements (“Masterplan”) defines recommended improvements for the City to implement over time, as funding is available. The document describes improvement options that respond to the diversity of views and opinions about the future of this roadway. The Mulholland Highway Master Plan for Capital Improvements is a long-range planning document that provides recommendations for traffic, circulation, roadway, and landscaping improvements along a 1.7- mile segment of Mulholland Highway. The corridor extends from Mulholland Drive to the southern (second) Old Topanga Canyon Road intersection. Figure 1 illustrates the limits of the Master Plan. The Master Plan provides the City with recommendations to respond to the City’s General Plan vision statement for the area, which is to restore the original beauty of the Mulholland corridor by developing a comprehensive Master Plan for the roadway.

Figure 1: Mulholland Highway Corridor The Master Plan includes input from the community, which has largely shaped the recommendations of the Plan. These recommendations include detailed circulation and landscaping improvements throughout the corridor. The corridor is divided into three zones that correspond to their existing characteristics. Zone 1 includes the segment from Mulholland Drive to Paul Revere Drive and is more suburban in nature. Zone 2 extends from Paul Revere Drive to the traffic signal in front of the high school. Zone 3 includes the segment from the high school to the southern (second) Old Topanga Canyon Road Mulholland Highway Master Plan for Capital Improvements ii August 1, 2004 intersection. This document presents information and recommendations for Zones 1 and 2 only. Zone 3 is considered to be a “transition zone” – between suburban and rural. The portion of Zone 3 between the two Old Topanga Canyon Road intersections will be analyzed by the City as part of another document. Key
