The Los Angeles District of the Army Corps, as part of its Operations and Maintenance Program, is proposing to perform repairs to the North and Middle Jetties at the entrance channel to Mission Bay, San Diego County, California.
Repair work would consist of resetting existing armor stone as needed and the placement of approximately 10,000-20,000 tons of new armor stone, reported the Corps.
USACE also added that the new stone would have a median stone size of 15-tons and a nominal diameter near 6 feet. Repairs are to be conducted by a barge-mounted crane, barges carrying rock, tugboats, and other various small boats.
Construction is currently expected to occur from April 2020 until August 2020, although the schedule is subject to change based on availability of funding, equipment and supplies, weather, and other issues.
