Del Mar Bluffs Repair Cost Put at $10.5M

March 25, 2021

Emergency repairs to the Del Mar Bluffs in Southern California are expected to cost about $10.5 million said the San Diego Association of Governments.

The work will involve construction of a 288-foot seawall and 18 vertical concrete and steel support columns tied into horizontal supports.

The project will seek to stabilize a section of the bluffs that collapsed in February within 35 feet of the tracks used by Amtrak’s Pacific Surfliner trains between San Diego and Los Angeles.

Since then Amtrak and Coaster commuter trains have slowed to 15 miles per house past the site. BNSF freight trains are restricted to 10 mph.

Train Speed Cut on Del Mal Bluffs

March 13, 2021

Trains are operating at reduced speed along a portion of the Del Mar Bluffs in Southern California despite a portion of it having recently collapsed.

The North County Transit District said another bluff failure is possible due to cracks that were observed during an inspection following the most recent collapse on Feb. 28.

The agency has warned the public to stay at least least 50 feet away from the top and bottom of the area.

The collapse last month reached within 35 feet of tracks owned by the transit district and used by Coaster commuter trains, Amtrak’s Pacific Surfliners, and BNSF freight traffic.

Funding Identified for Del Mar Bluffs Project

January 16, 2021

Funding has been identified for a project to stabilize the Del Mar Bluffs in California on the route of Amtrak’s Pacific Surfliners.

The Los Angeles-San Diego-San Luis Obispo San Diego Regional Rail Corridor Working Group said this week it has found possible sources of the $98.7 million needed to pay for the project along a 1.7-mile section of track alongside the Pacific Ocean.

The funding would include $36.2 million from the California Transportation Commission’s Trade Corridor Enhancement Program; $11.5 million from the Federal Railroad Administration; $9.5 million would come from the North County Transit District; $4.9 million from the California State Transportation Agency’s Transit and Intercity Rail Capital Program; and $3.1 million from the California Natural Resource Agency. 

The San Diego Association of Governments would contribute $10 million and another $13.5 million would come from grants and project savings

A California State Transportation Agency report said LOSSAN has been seeking to stabilize the bluffs for the next 30 years by making them more resilient to rising sea levels.

The bluffs are eroding at an average of 6 inches a year. The center of the track in this section of railway is within 15 feet of the cliffside at the nearest point.

Also using the route are Metrolink and Coaster commuter trains as well as freight trains serving the Port of San Diego. 

Funding Awarded to Improve California Tracks

July 2, 2019

State funding has been awarded to stabilize a portion of the route used by Amtrak’s Pacific Surfliner trains near San Diego.

The North County Transit District  will receive $6.13 million from the state for its Del Mar Bluff stabilization projects.

The tracks are also used by NCTD trains, Metrolink, PacSun and BNSF. Officials said the bluffs have experienced natural erosion that has led to six bluff failures since last summer.

The project will be undertaken in two phases. One phase will secure the bluffs for the next 20 to 30 years by evaluating the site’s seismic and static stabilization needs, the addition of piling and tie backs, replacement of old drainage structures and localized lagging as bluff retreat accelerates.

The other phase involves funding the analysis, selection, environmental clearance and development of construction plans for additional stabilization measures. The measures would include bluff toe protection, bluff face stabilization, lagging installation and the consideration of coastal access.
