Transit district studying options for addressing second 'area of concern'
A second spot may need repairs after an unusually wet Thanksgiving Day storm closed the railroad tracks at Del Mar for work over the weekend, transit district officials said Monday.
The main washout came within about 20 inches of the railroad ties at the edge of the fragile coastal cliff.Trains continued through the area at slow speeds on Friday, and traffic was suspended Saturday for the repair work. After a contractor completed the repairs, service resumed on Sunday. Most of the storm drains are on the railroad’s right-of-way, but they are fed by rainwater from the streets, parking lots and other impermeable surfaces in Del Mar. When the drains are clear, they carry rainwater under the tracks and down to the beach without eroding the cliffs.
“It is not uncommon for heavy rain in Del Mar to trigger collapses in unstable cliffs,” said Adam Young, a researcher at Scripps Institution of Oceanography. “However, wave erosion at the cliff base is a fundamental process that creates the cliff instability and allows the rainfall and groundwater to act more efficiently.”
Last week’s storm runoff washed out the wood lagging, a wall of timbers, that held back the soil between concrete columns, or piles, sunk deep into the earth. The area is just south of Seagrove Park, an area where the tracks are 25 to 40 feet above the beach. Farther south the cliffs are higher.
