State Submerged Lands
State-owned tracts in offshore waters and coastal bays. These tracts are owned and leased by the GLO.
Oil & Gas Leases
Oil and Gas Leases managed by the Texas General Land Office.
Oil & Gas Lease Sale Nominations
Nominations for the upcoming oil/gas sealed bid lease sale (tracts located in bays and the Gulf of Mexico). This dataset is updated one month prior to each lease sale.
Oil & Gas Pooling Agreements/Units
Oil and Gas pooling agreements managed by the Texas General Land Office.Professional Services Data
Coastal Leases (Point Locations)
Locations of structures and activities permitted by the GLO within state-owned land and waters. Includes features represented by a single point location, such as piers, docks, breakwaters, and shoreline protection projects.
Coastal Leases (Polygonal Locations)
Locations of structures and activities permitted by the GLO within state-owned land and waters. Includes areal features such as dredging areas, parks, mitigation projects, and conservation easements.
Pipelines and Miscellaneous Easements
Pipelines located in state-owned submerged lands and other areas along the Texas Gulf Coast.Oil Spill/Coastal Response Data
Beach Access Points
Public beach access points. Mapped by the GLO in cooperation with coastal towns and counties.
Colonial Waterbird Rookery Areas
Locations of waterbird rookery sites in the coastal counties of Texas. Information compiled by the Texas Colonial Waterbird Society.
Dispersant Use Pre-Approval Zone
Boundaries of pre-approved area for use of dispersant in oil spill response. Boundaries were created by combining the 10-meter offshore bathymetric contour and the three nautical mile line. The boundary follows whichever line is farthest offshore. Data are not to be used for navigation or for mapping at large scales.
Environmental Sensitivity Index Shoreline
Shoreline of Texas with Environmental Sensitivity Index classification (sensitivity of shoreline habitats to oil contamination and removal). Classification conducted by the University of Texas Bureau of Economic Geology.
In-Situ Burn Exclusion Areas
Areas designated by the Oil Spill Regional Response Team VI where in-situ burns are prohibited.
Priority Protection Habitat Areas
Priority coastal habitat areas to be protected during oil or hazardous material spills on the Texas coast. Areas were identified and prioritized by TPWD and GLO personnel in cooperation with other entities.
Species/Habitats
Coastal distribution of animals, plants and habitats potentially at risk from oil spill damage or response activities. Mapped as part of a joint project involving GLO, TPWD and other entities.
Three Marine League Line
The boundary between state and federal jurisdiction located three marine leagues (approx. 10 miles) offshore in the Gulf of Mexico.
Three Nautical Mile Line
Line of demarcation three nautical miles offshore of the Texas coast in the Gulf of Mexico.Coastal Management Program Data
