(b) Overview of the Proposed Project

Project Location

The Project Site is located in the City of Santa Clarita, California located about 35 miles north of
Downtown Los Angeles. The Project Site is located at the intersection of Lyons Avenue and Railroad
Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The
th
Master’s University and northwest towards the intersection of 12 Street and Arch Street. The Project Site
th
also includes the closure of an at-grade crossing at the intersection of Railroad Avenue and 13 Street.
The limits for the Lyons Avenue/Dockweiler Drive extension (“Project Site”) are from Railroad Avenue
on the west to the future Master’s University Master Plan Dockweiler extension to the east.

Overview of the Environmental Setting

The Project Site is currently zoned for MXN (Mixed Use Neighborhood). The portion of the Project Site
that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The General Plan land
use designation of the Project Site is Mixed Use Neighborhood (MXN). The General Plan states that areas
with a MXN designation should be developed to create neighborhoods that combine residential uses with
complementary commercial services, including retail and office uses. MXN zoned areas should be located
in close proximity to public transit and provide roadway and trail linkages to adjacent development. The
PI zoning designation identifies lands that are used for various types of public or/and community serving
facilities owned and operated by public agencies, special districts, nonprofit organizations and other
entities. Allowable uses include civic and governmental offices, public works yards, public or private
schools, libraries, day care centers, airports, hospitals and supporting medical facilities, museums, fire
stations, police stations, landfills, and prisons. The Project Site is also located in the Placerita Canyon
Special Standards District (PCSSD) and is part of the North Newhall Area (NNA), which includes a
Mixed Use Overlay Zone.

Overview of the Proposed Project

The Proposed Dockweiler Drive Alignment Project is a multi-phased capital improvement project being
coordinated by the City of Santa Clarita and The Master’s University to improve circulation and access to
the Placerita Canyon and Newhall Communities. The proposed connection and extension of Lyons
Avenue to Dockweiler Drive is identified in the Circulation Element of the City’s General Plan as one of
the primary east-west arterials through the City of Santa Clarita that would provide a through connection
from Sierra Highway to Railroad Avenue.

The Proposed Project would extend Lyons Avenue from its existing terminus at Railroad Avenue,
eastward to Dockweiler Drive to provide a T-intersection, and would extend northwest to connect with
th
the intersection of Arch Street and 12 Street and southeast towards the General Plan alignment for
Dockweiler Drive at The Master’s University. The Proposed Project also includes the closure of an
th
at-grade railroad crossing at the intersection of 13 Street and Railroad Avenue and the addition of a new
at-grade railroad crossing at the intersection of Railroad Avenue and the proposed Lyons Avenue
intersection. The Lyons Avenue/Dockweiler Drive extension would extend to the approved alignment of
