CLCWA History
The Authority was created by House Bill 1003, 58th Legislature of Texas, Regular Session, on May 6, 1963 (compiled as 8280-280, Texas Revised Civil Statutes). The Authority was created to provide, operate, and maintain waterworks systems, sanitary sewer systems, storm sewer systems, and drainage facilities to serve land within its boundaries. The Authority operates under the authori

ty of the Texas Constitution, Texas Revised Civi1 Statutes, Article 8280-280 and Chapters 49 and 51 of the Texas Water Code, as amended. Location and Size
The Authority is situated almost entirely in southeast Harris County in the Clear Lake area, about 20 miles southeast of downtown Houston. Its northwest to southeast boundary is State Highway 3. The Authority surrounds the Johnson Space Center on three sides. Ellington Field is located just outside the Authority's northwest boundary. At the time of its creation on May 6, 1963, the Authority consisted of 12,269 acres. Through various annexations, the current total land area is approximatly 16,106 acres. Approximately 13,490 acres have been developed for commercial, residential, and public recreational use. The Clear Lake City Water Authority is the largest water district in Texas. Topography and Drainage
The general area of the Authority ranges in elevation from 10 feet mean sea level along the extreme eastern boundary to about 35 feet mean sea level along the northwestern boundary. Substantially all existing areas or areas proposed for development within the Authority are above the projected 100-year flood plain. In the general area of the Authority, there are three well-defined major watersheds. The three major drainage channels are Horsepen Bayou on the west, Armand Bayou in the central area, and Cow Bayou on the south and discharge through Clear Lake into Galveston Bay. Drainage of the developed subdivisions is accomplished by means of enclosed storm sewer systems which outfall into detention ponds and/or improved channels of the three major streams. Information on our new Storm Water Environment Managment Program will be available soon on the Storm Water tab. The Authority is working to better protect bayous from receiving excessive solids and oily substances.
