    includes 42 miles of railroad right-of-way (ROW), Houston Ship Channel with tributary bayous and streams within Harris County, 9,000 acres of dredged material placement areas (13 sites) and all other Port Houston properties where other entities are permitted use by the Port Commission.














Port Houston owns property as shown on the attached map.

Generally, Port Houston property is along the Houston Ship Channel and railroad corridors, 13 dredged material areas, and the submerged lands beneath and adjacent to the ship channel in Harris County. Port Houston manages this property to facilitate commerce and environmental quality at the port. Port Houston grants licenses and leases on port property to facilitate future growth while protecting the interests of navigation and the public.
