Seabrook is a city in Harris County in the U.S. state of Texas, with some water surface area located withinChambers County. The population was 11,952 at the 2010 census.
The piece of land was purchased by Seabrook W. Sydnor in 1895. In March 1903, the Seabrook Company of Houston created a layout of the proposed Seabrook Town site. The new town attracted fishermen, merchants and even a few residents.Despite damage from Hurricane Carla, a bridge linking Seabrook and Kemah was completed in 1961. With the opening of the bridge and the Johnson Space Center (JSC) in Houston, Seabrook's population rose to approximately 6,000.In 1986, the decision was made to start the construction of a fixed-span bridge that was tall enough for sailboats to pass under. After this bridge was finished, Highway 146 was linked all the way from Galveston to Texas State Highway 225. This spurred a further increase in the population of Seabrook to its present level of nearly 12,000 people. Seabrook's residents are quite diversified and are employed in a variety of professional positions. Quite a few residents have ties to the chemical and oil industry as well as the NASA space program.
