The Texas coast is a system of barrier islands, lagoons, estuaries, plains, and rivers on a low-lying coastal plain with gently sloping topography. Embedded in this natural and dynamic system are a variety of human developments and activities including oil and gas production, heavy industry, shipping, commercial fishing, recreational fishing, agriculture, tourism, and small and large communities dotted throughout the landscape. The natural systems of the coastal plain, however, are dynamic and subject to sudden hazards such as floods, storm winds, storm surge, and erosion superimposed on longer-term processes of ongoing erosion caused by sediment supply changes, shifting habitats, sea level rise (SLR), and climate change. Given the vulnerability of the Texas coast, this study assessed the impacts of relative sea level rise (RSLR) and associated enhanced storm surge to better understand the relative susceptibility to negative impacts on the natural and built environments. This study was part of the third publication of the Texas Coastal Resiliency Master Plan (TCRMP) published in April 2023. TCRMP is an ambitious coastal planning effort by the Texas General Land Office (TGLO) to make the Texas coast more resilient to hazards. For this study, the Harte Research Institute (HRI) developed a dynamic modeling framework to assess quantitative information regarding the impacts of SLR and associated enhanced future storm surge caused by higher sea levels and changes in land cover. For the 2023 TCRMP, two SLR scenarios were modeled - Intermediate-Low scenario (0.5 m of SLR by 2100) and Intermediate-High scenario (1.5 meters of SLR by 2100). The relative component of sea level rise was determined on a regional basis by deriving an average trend from long-term records of coastal tide gauges. Similarly, nineteen synthetic storms, ranging in severity from Category 1 to 3, making landfall near major bay systems or city centers across the Texas coast, were modeled for both the current and 2100 landscapes. The coupled hydrodynamic storm surge model, Advanced CIRCulation (ADCIRC) and Simulating Waves in the Nearshore (SWAN) was used to identify the threat posed by storm surge and nearshore waves to communities and the coastal ecosystem in both the current and 2100 landscapes. To better understand the relative vulnerability to storm surge from the full variety of modeled storms, a storm surge vulnerability map was developed by considering all modeled storms in the present and future landscape scenarios. The result of this modeling served as input for geohazards maps that show current and future exposure to changing environmental dynamics in an area. The geohazards maps were essentially a synthesis of all the modeling work done for this study in one product, providing a detailed representation of the present and future state of the coastal plain, highlighting areas that are most susceptible to hazards, and identifying critical coastal environments to preserve or avoid. This dataset contains geohazards maps with two SLR scenarios modeled for four coastal planning regions covering the Texas coast.

The digital data was generated from the Geographic Information System of the Railroad Commission of Texas. Base map information was obtained directly from U.S. Geological Survey 7.5 minute quadrangle maps. Patent Survey lines from Texas General Land Office maps were interpreted as accurately as possible over the US Geological Survey base. Oil and gas well data or pipeline data (if included) was obtained from public records at the Railroad Commission. The information provided by this system is being continually updated and refined. The data is intended solely for the internal use of the Railroad Commission, which makes no claim as to its accuracy or completeness.Field Definitions can be found at: https://rrc.texas.gov/media/kmld3uzj/digital-map-information-user-guide.pdf

State-owned tracts in bays gulf three marine leagues (about 10.3 miles) into the Gulf of Mexico, owned and leased by the GLO, with codes added that reflect restrictions and concerns associated with leasing of these tracts. Disclaimer: The Texas General Land Office makes no representations or warranties regarding the accuracy or completeness of the information depicted in these mapping applications, in downloads from this page, or the data from which it was produced. These datasets ARE NOT suitable for navigational purposes and do not purport to depict or establish boundaries between private and public land.

The Texas Automated Buoy System contains daily oceanographic measurements from seven buoys off the Texas coast from Brownsville to Sabine. The Texas General Land Office supports this system as part of its mission to mitigate the effect of catastrophic oil spills on the Texas Coast. Buoys communicate surface currents and water temperature measured at 2m depths in near real time via cell phone and commercial satellite digital data links. Data are available within a few hours of collection, but gaps in the data may occur.

The provided relationships within the database provide linkage that allows for cradle to grave understanding of Resiliency Strategies. The linkage allows understanding of strategy to project origin, with information regarding how projects were screened and evaluated and the resources that allowed that process to occur.

This coverage contains boundaries of Texas state parks, wildlife management areas (WMAs) and fisheries facilities. The boundaries were collected from Texas Dept. of Transportation county maps,General Land Office data, Texas Parks and Wildlife Dept. (TPWD) Public Lands Stackhouse mylar sheets from the Survey Section, other TPWD Survey Section data, Park or WMA boundaries on U.S. Geological Survey 7.5 quads, TPWD Wildlife Division boundaries drawn on USGS 7.5 quads from Penny Bartnicki (Wildlife Facilities Coordinator). When completem this coverage should include boundaries for all state parks, wildlife management areas and fisheries facilities.Field Definitions:For field definitions, contact Harte Research Institute

Seagrass is a critical estuarine habitat. Resource managers need to know the extent and distribution of seagrass within the estuary to ensure that negative impacts to these critical habitats are avoided. This file was created to inform the Spatial Planning Tool for Oyster Mariculture in Texas, which requires avoidance of seagrass habitats by 200 feet, but can be used to inform any coastal project review where seagrass habitats must be avoided. Information about the data source, including survey year, are included as attributes so that older features can be interpreted with discretion.All known and inventoried seagrass data layers were merged to create the product, including the various seagrass Status and Trends reports in Texas (Pulich et al. 1997 (CCBEP), Handley et al. 2007 (USGS), White et al. 2002 (BEG)), the NOAA Texas Benthic Atlas (Finkbeiner et al. 2007), and TPWD authoritative mapping efforts. These files were projected to the same datum (WGS 84). All inconsistent attributes were deleted, and a "SurveyName" attribute was added to each file to reference the source data. Files were then merged, and attribute information was added to each feature according to the "SurveyName". Attributes include the survey year, survey method (aerial imagery or transect), original surveying agency ("Source"), survey extent (SurvLocation), the Minimum Mapping Unit (MMU), and accuracy (if reported). The individual feature layers are also hosted by TPWD-Coastal Fisheries. This layer only displays the extent (presence/absence) of seagrass based on these surveys - habitat qualifiers (such as continuity or density) are not included. TPWD will update this layer on an annual basis. Last update, May 2021.
