Del Mar forges levees to lessen flood damage
A series of living levees — earthen embankments — along the San Dieguito River could help protect affordable housing at the fairgrounds and homes in Del Mar’s North Beach. As part of its sea rise planning, Del Mar has completed a preliminary conceptual plan for three living levees; structures that slope gently to combine flood protection with habitat restoration. … The levees will reduce, but not eliminate flood risk.
