Clear Lake City is a master-planned community located in southeast Harris County, Texas, within the Bay Area of Greater Houston. It is the second-largest master-planned community in Houston — behind Kingwood. The majority of the community lies in the corporate limits of Houston, while a small eastern portion is in the city limits of Pasadena and a small portion within the city limits of Taylor Lake Village. The community is adjacent to NASA's Johnson Space Center, as well as other major aerospace companies—including Boeing and Lockheed-Martin. Clear Lake City has the largest Asian American concentration within any master-planned communities inside the city of Houston. The community and its adjacent areas have a high concentration of engineers due to both NASA and the local petrochemical industries.
