Most of this land was acquired to mitigate the expansion of Lindbergh Field, when the airport operations were under the Port's control.
As part of this mitigation effort, 722 acres were transferred to the State of California. This ultimately led to the creation of the South San Diego Bay National Wildlife Refuge. The remaining 114 acres were set aside for future development.
When the San Diego County Regional Airport Authority (Airport) became a separate agency on January 1, 2003, the Port retained ownership of Pond 20, and the Airport took over the remaining acreage.
Pond 20 currently is undeveloped, and the Port is working with the cities of San Diego and Imperial Beach to explore opportunities for future uses.
An agreement, known as a Memorandum of Understanding (MOU), has been developed between the Port of San Diego and the cities of San Diego and Imperial Beach, which outlines a process to solicit input and develop project concepts for Pond 20.
