FINAL STAGE KICKS OFF FOR $117M RESTORATION OF SAN ELIJO LAGOON
Project aims to improve health of the reserve, slow erosion along shoreline
A floating, diesel-powered dredge sucked sand out of the San Elijo Lagoon on Thursday — pumping the wet, gray material through a long plastic pipe onto Cardiff State Beach.
Last week marked the start of the final leg of a $117 million restoration project, which nearby communities hope will also slow shoreline erosion. The vision was initially proposed in the 1990s but didn’t secure funding until 2017.
Specifically, the California Department of Transportation is creating a roughly 80-foot channel under Interstate 5 to allow more saltwater into the eastern parts of the wetlands. For decades, I-5 trapped freshwater runoff in the lagoon, encouraging the growth of invasive
plants, such as cattails and bulrushes.
The restoration, which is expected to continue through the winter, has also deepened the lagoon with previous dredging and reintroduced
native plants, such as cordgrass, which provides habitat for the federally endangered Ridgway’s rail.
The lagoon is already starting to show signs of healing, said Doug Gibson, executive director and principal scientist for the Nature Collective, formerly the San Elijo Lagoon Conservancy.
“We found our first octopus in the lagoon,” he said. “There are scallops all over the bottom. We have needlefish that we’ve never seen in the lagoon before.”
Caltrans and the San Diego Association of Governments partnered on the project with the Nature Collective, as well as the city of Encinitas. It’s part of the $6 billion North Coast Corridor Program, which includes the widening of I-5 and double-tracking the adjacent rail corridor between La Jolla and Oceanside.
This is a “once-in-a-lifetime” opportunity, said Jared Corbitt, resident engineer with Caltrans overseeing the endeavor. “This is one of the largest habitat restoration projects the state has done.
“The birds have just taken off,” he added. “There’s a lot of aquatic species that we’ve never seen before. We have sea lions in here.”
The dredging started Tuesday
