From the 1950s to the 1990s, the Market Creek Plaza property was owned and operated by Langley Aerospace, Inc. Langley built and tested aircraft for space travel. These operations required the use of the volatile organic compounds (VOCs), including trichloroethylene (TCE) and tetrachloroethene (PCE), which were spilled or otherwise released into soil and groundwater. The Langley facility closed in the early 1990s.

After the facility closed, environmental investigations and cleanup work was conducted to prepare the site for redevelopment. The San Diego County Department of Environmental Health oversaw the removal and cleanup of a 2,000-gallon tank that stored machine oil and DTSC oversaw cleanup of the site from 1990 through 1996.

As part of the case overseen by DTSC, soil and groundwater conditions were studied, and it was concluded that no further action was required because TCE and PCE were below risk-based screening levels. The site was redeveloped into the current commercial shopping center in 2000.
