Construction crews will begin sand replenishment at Cardiff State Beach this week as part of a project to restore the San Elijo Lagoon.
A total of 300,000 cubic yards of sand will be deposited along the coastline with a dredge from Ross Island Sand & Gravel working around the clock, Monday through Saturday, for six weeks. Nearby residents and visitors will likely hear noise and see nighttime lights in the lagoon.
In later phases of the lagoon restoration, crews will replace the sand removed from the lagoon’s central basin with high-nutrient sediment transferred from various lagoon channels to improve tidal flow and overall water quality.
The restoration is part of the San Diego Association of Governments‘ North County corridor project — Build NCC — that includes extending existing carpool lanes on Interstate 5 north to Route 78, double-tracking the rail line, replacing the highway bridge over the San Elijo Lagoon, and replacing the rail bridges over the San Elijo and Batiquitos lagoons,
Construction under the Build NCC plan began in early 2017 and will be complete by 2021.
