Asilomar Boulevard Landslide Mitigation Project (E1907673)

The City of Los Angeles (City) Bureau of Engineering (BOE) is preparing an environmental impact report (EIR) for the proposed Asilomar Boulevard Landslide Mitigation Project (proposed Project).  The Project site includes an approximately 600-foot-long segment of the Asilomar Boulevard right-of-way (ROW) between Almar Avenue and Wynola Street.  Asilomar Boulevard provides approximately 1,350 linear feet of local east-west vehicular and pedestrian access in the southwestern portion of the Pacific Palisades community of the City of Los Angeles.

The public comment period for the scoping process is from September 28, 2017 – October 27, 2017.

Background

The portion of Asilomar Boulevard between Almar Avenue and Wynola Street ROW known as the Asilomar Landslide has dropped downward approximately 3 feet and shifted laterally in the south-eastern portion of the Project site.  As a result, several surface cracks subparallel to the slope are evident along the southern portion of the roadway.  The more severe cracks have been periodically filled in with sealers and/or asphaltic concrete.  This south-eastern portion of the roadway is currently blocked off from vehicular traffic using traffic cones and signage.

Proposed Project

The fundamental purpose of the Proposed Project is to stabilize the Asilomar Landslide to prevent further sliding of the roadway in the area. The Proposed Project would seek to limit major earthwork and construction activity by using a construction method called Cement-Deep Soil Mixing (CDSM).  Working within the Asilomar ROW, a specialized drill rig would mix the existing soil material with cement, forming approximately 2- to 8-foot-wide columns, depending on final design, up to a depth of 120 feet, which would strengthen the subsurface material and stabilize the slide area of the roadway.  The CDSM columns would be installed in a grid pattern located entirely within an approximately 600 foot long by 50 foot wide portion of the Asilomar Boulevard ROW.  Following installation of the CDSM columns, the Project site would appear similar to existing conditions, as all structures would be installed below the ground surface and the street will be re-paved.  The Proposed Project would also maintain the natural look of the existing slope south of Asilomar Boulevard.

Scoping Meeting

A public scoping meeting will be held to receive input on the scope and content of the Draft EIR. The meetings will be held using an open house format to share information regarding the proposed Project and the environmental review process, and to receive verbal or written comments and public testimony. City staff and environmental consultants will be available and a formal presentation is scheduled. You may stop by at any time during the meeting to view materials, ask questions, and provide written comments. The City encourages all interested individuals and organizations to attend the meeting.

A scoping meeting will be held to obtain input on the scope of the contents of the EIR, as well as to present information on the Proposed Project design.  This meeting will be held at the following date, time and location:

Tuesday, October 10, 2017 from 6:45 p.m. to 8:45 p.m.
Gilbert Hall
Palisades Charter High School
15777 Bowdoin Street
