Background Information of the Site

The National Geospatial – Intelligence Agency (NGA) SS-18 site located at 3200 S. Second St., St. Louis, has a long and rich history that began in 1803 with the Lewis and Clark Expedition and corresponding efforts to explore and map the Louisiana Territory. From 1803 until the beginning of World War I, U.S. mapping and charting technologies and practice remained unchanged. It was during World War I that photo processing and printing operations began at the site. World War II brought an even greater demand for mapping services. Aerial photography improved through advancements in aircraft, cameras and film. 

In 1972, budgeting concerns prompted the armed services to combine their mapping and charting abilities into a centralized agency called the Defense Mapping Agency. In 1996, the National Imagery and Mapping Agency (NIMA) was created by the U.S. Congress, the Central Intelligence Agency and the U.S. Department of Defense, combining imagery intelligence with map-based imagery to enhance the country’s mapping and imagery analysis efforts. 1999 brought an end to printing operations at NIMA. In 2002, NIMA phased out all photo processing as they switched to digital media.

On Nov. 24, 2003, President George W. Bush signed the 2004 Defense Authorization Bill which authorized NIMA to change its name to the National Geospatial-Intelligence Agency. NGA currently serves military, civil and international geospatial intelligence needs and supports national security.

Environmental Restoration at the Site

An environmental remedial investigation report is being prepared to address potential releases due to past hazardous waste handling and disposal practices of solvents, metals, petroleum, oils, paints and pesticides at the current NGA SS-18 site.

Plans are underway to relocate NGA SS-18 offices and campus to a new western headquarters on a 99 acre site located in north St. Louis sometime in 2023.
