U.S. Military Economic Footprint In San Diego Is Growing, New Report Says

Defense industry personnel and military operations continue to be a significant driver of San Diego’s economy and, according to a new report, are projected to grow in the coming years.

According to the 2019 San Diego Military Economic Impact Study, 354,000 military-connected jobs accounted for 22 percent of all jobs in the region. This amounts to a $51 billion contribution to the local economy, or one-fifth of San Diego’s total gross regional product (GRP).

The report, released today by the San Diego Military Advisory Council, projected this impact will increase 7 percent next year as the national defense strategy continues to shift toward the Pacific, and more Navy ships are home-ported in San Diego.

1951: Construction Milestone for Pipeline 2, San Vicente Aqueduct

When World War II concluded, most experts expected San Diego’s population to decrease, but that was not the case. Pipeline 1 proved inadequate to meet the region’s water needs. Drought years in 1950-51 increased concerns about water shortages.

The Water Authority appealed to the U.S. Navy to help build a second pipeline. It was willing, but its hands were tied by the Bureau of Reclamation, which built the first pipeline because of the wartime emergency. With the war over, it could not fund the project unless Congress authoritzed the Navy to request it.

The first chairman of the San Diego County Water Authority, Fred Heilbron, undertook the effort to create consensus to build Pipeline 2. Among his tactics: crashing a breakfast meeting between the Secretary of the Navy and then president of the Metropolitan Water District board of directors; and enlisting help lobbying Congress including Senator Richard M. Nixon.

The effort paid off. Officials celebrated every milestone of construction, including the installation of the first section of pipe.

1947: Construction of the First San Diego Aqueduct

San Diego became a hub of Naval Activity after the Japanese bombed Pearl Harbor and the United States entered World War II in 1941. The city’s population doubled in two years, and water use also doubled. It was clear the city and the Navy would soon need water from the Colorado River. An aqueduct for bringing that water to San Diego became a top priority.

The Navy was willing to help build the aqueduct, and let the City of San Diego pay it back. On November 28, 1947, the first Colorado River water finally flowed south from the Colorado River aqueduct’s western end in Riverside County for 71 miles into the City of San Diego’s San Vicente Reservoir near Lakeside via the San Vicente Aqueduct, now known as Pipeline 1 of the First San Diego Aqueduct. It ran over some of the county’s most rugged terrain and could deliver 65,000 acre-feet per year. At a time when all of San Diego County had less that three weeks’ water supply remaining, the completion of the project came just in time.
