The proposed project is a grade separation of the existing grade crossing at Placentia Avenue and the BNSF railroad tracks in the City of Placentia. The project objective is to improve public safety, both for vehicular and pedestrian movement through the project area. The project will also reduce traffic congestion and queuing cause by the existing at-grade conflict between the roadway and railroad tracks. The existing railroad line is heavily utilized freight corridor, and the proposed grade separation is also anticipated to improve the safety of railroad operations. Project features include right-of-way acquisition, storm drain improvements, utility relocation, hardscape and landscape treatments intended to enhance the appearance of the project area, and dedicated pedestrian facilities.
Section 21080.13 of the Public Resources Code lists the statutory exemption for railroad grade separations as follows: "This division shall not apply to any railroad grade separation project which eliminates an existing grade crossing or which reconstructs an existing grade separation." The Placentia Avenue Underpass meets this definition.
