Southern California Edison recently presented a community outreach event to give the public a progress report on the final phase of the San Dieguito Lagoon restoration.
David Kaye (SCE Manager of Environmental Projects) summarized the project accomplishments to date. Mike Furby (Marathon Construction) discussed the dredging operations and Dick Bobertz (JPA) outlined the existing and proposed trail connections.

160 acres of wetlands have been restored.

Berms have been constructed and vegetated to contain the river flow during potential floods and to protect two major new wetlands north and south of the river.

Three new nesting sites have been created, power lines relocated and treatment ponds built adjacent to a commercial area.

ADA access trail has been constructed at North Beach.

A boardwalk now crosses the wetlands south of the fairgrounds and a trail allows passage under the I-5 freeway and will soon lead hikers to El Camino Real.

The old Grand Avenue Bridge had been converted to a View Point for the lagoon.
Outstanding projects at the western end of the lagoon are scheduled to be completed in the next 9 months.

Just east of Jimmy Durante Boulevard the river makes a sharp bend where intensified flow undermines its southern bank; new riprap will armor the riverbank.

Sand has accumulated in the inlet channel over the past and hinders tidal flow.

65,000 cubic yards of sand will be removed in the coming winter months. A floating dredge will first operate east of Jimmy Durante Boulevard and will pump sand to a stockpile area where it will be dried and placed on upland sites. Sand suitable for beach use will be added to the Del Mar beach. A reconfiguration of the inlet will move the river channel northward.

Extensive beach monitoring will take place. Quarterly beach profiles will be measured and compared to 32 years of beach records. These will be analyzed by independents reviewers with the participation of the California Coastal Commission.

Southern California Edison is committed to keep the inlet open to tidal flow in perpetuity.
