Dear Dr. Pollack,

The California Department of Transportation (Caltrans) proposes to install a temporary traffic
signal system along a segment of State Route 126 (SR-126) at post mile (PM) 2.73 in Los
Angeles County, California (see attached map for specific location). Caltrans proposes to install
a temporary traffic signal system at the intersection of SR-126 and Chiquito Canyon Road,
modify the existing pavement delineation, and connect the permanent power supply line from
Southern California Edison (SCE). The scope of the project consists of the following
improvements:
• Install traffic signal system using wood poles augured 11-feet below original ground
surface and span wires at Chiquito Canyon Road intersection.
• Modify the existing pavement delineation.
• Connect the permanent power supply by trenching 60 feet of conduit to a depth of
approximately 30-inches fi*om SCE.

The purpose of these improvements is to reduce the fi*equency and severity of accidents,
particularly broadside collisions at the intersection of SR-126 and Chiquito Canyon Road. The
temporary signals will provide the right-of-way to motorists in situations where gaps within the
traffic stream are not available.

Caltrans is conducting a study of potential impacts to historical resources as a result of the
proposed project, as required imder the California Environmental Quality Act. As such, we are
seeking information from potentially interested parties, such as your organization. Caltrans
would appreciate any input you may provide regarding the presence of potential or known
historical resources within the project location and/or immediate vicinity. Early identification of
historical resources will ensure their consideration and protection to the maximum extent
feasible.
