INTRODUCTION This report documents the assumptions, methodologies, and findings of a study conducted by Kaku Associates, Inc. to evaluate the potential traffic and circulation impacts of the California State University, Northridge (CSUN) Master Plan. The CSUN campus is located at 18111 Nordhoff Street in the Northridge area of the City of Los Angeles, California. PROJECT DESCRIPTION The CSUN campus is generally bounded by Devonshire Street to the north, Nordhoff Street to the south, Zelzah Avenue to the east, and Darby Avenue to the west. The proposed Master Plan envisions a series of improvements to the campus to accommodate potential student growth through the year 2035, including new or renovated academic buildings and facilities, campus housing, campus parking facilities, and support facilities. Based on information provided by the university, the number of student full-time equivalents (FTE) for the academic year 2003-2004 is estimated at 24,473. Over the period of Master Plan buildout to year 2035, enrollment is projected to increase to approximately 35,000 FTE students, an increase of about 40%. Figure 1 illustrates the proposed Master Plan, indicating potential locations of proposed new academic buildings, student housing, faculty/staff housing, and parking structures. The orange shading in Figure 1 indicates the locations of the proposed academic buildings, the yellow shading indicates the proposed locations of new student housing, the gold shading indicates the locations of proposed faculty/staff housing, and the blue shading indicates the proposed locations of
