Four Corners Area
Water and Sewer Facilities
I. Project Planning Area
A. Project Location- The planning area for the Four Corners water and sanitary sewer
study encompasses approximately 1,775 acres of land located in north central Fort Bend
County, Texas. The planning area boundaries are generally defined by State Highway 6
on the east, McKaskle Road to the south, FM 1464 to the west and the southern
boundary of South Mission Glen MUD to the north. Major roadways within the
planning area include Richmond-Gaines Road which runs north-south through the area
and Boss Gaston/Old Richmond Road which traverses east to west across the north
central part of the planning area connecting State Highway 6 with FM 1464. Both roads
are two-lane asphalt roadways with open ditch drainage. The entire planning area is not
located within the corporate limits of any city, but lies wholly within the extra-territorial
jurisdiction of the City ofHouston.
Much of the service area consists primarily of open pasture/range land with sparse tree
cover. Ground elevations within the area indicate that the overall slope of the area is
from north to south with elevations ranging from 85 feet to 95 feet mean sea level (1928
NGVD). Red Gully flows from north to south through the area and provides primary
outfall drainage. Smaller lateral channels convey flows to Oyster Creek (south of the
area) and to Red Gully itself.
B. Environmental Resources - The Colorado, Brazos, Trinity, Neches and Sabine
Rivers originate north of the Texas Coastal Plain. They flow southward through the plain
to the Gulf of Mexico. These rivers are pro-Pleistocene in age. Smaller creeks such as
the Oyster Creek and Jones Creek developed during the Pleistocene and parallel the
major waterways. Fort Bend County is located in the Western Gulf section of the Coastal
Plain,
Fort Bend County's location in the Western Gulf section of the Coastal Plain places it
within a subtropical belt The modem climate is characterized by high humidity. The
