Carlsbad beaches, it was placed in a future borrow pit within the outer basin of the Agua Hedionda lagoon

Carlsbad, both south of Agua Hedionda Lagoon and north of Batiquitos Lagoon. 1.6 million cy of sand were
placed on Encinas Beach (near proposed South Carlsbad receiver sites) and 200,000 cy were placed adjacent
to the lagoon inlet (proposed Batiquitos receiver site). Continued dredging and placement is planned to
maintain the lagoon, and may need to be conducted annually. Dredging and placement in May 1999 yielded
10,000 cy; half of which were placed on Carlsbad beaches and the other half of which were placed in least
tern nesting areas in the lagoon. The most recent dredging (February 2000) anticipates placement of 50,000
to 70,000 cy at Encinitas/South Ponto Beach.
