This site provides access to download an ArcGIS geodatabase or shapefiles for the 2017 Texas Address Database, compiled by the Center for Water and the Environment (CWE) at the University of Texas at Austin, with guidance and funding from the Texas Division of Emergency Management (TDEM). These addresses are used by TDEM to help anticipate potential impacts of serious weather and flooding events statewide. This is part of the Texas Water Model (TWM), a project to adapt the NOAA National Water Model [1] for use in Texas public safety. This database was compiled over the period from June 2016 to December 2017. A number of gaps remain (towns and cities missing address points), see Address Database Gaps spreadsheet below [4]. Additional datasets include administrative boundaries for Texas counties (including Federal and State disaster-declarations), Councils of Government, and Texas Dept of Public Safety Regions. An Esri ArcGIS Story Map [5] web app provides an interactive map-based portal to explore and access these data layers for download.

The address points in this database include their "height above nearest drainage" (HAND) as attributes in meters and feet. HAND is an elevation model developed through processing by the TauDEM method [2], built on USGS National Elevation Data (NED) with 10m horizontal resolution. The HAND elevation data and 10m NED for the continental United States are available for download from the Texas Advanced Computational Center (TACC) [3].

The complete statewide dataset contains about 9.28 million address points representing a population of about 28 million. The total file size is about 5GB in shapefile format. For better download performance, the shapefile version of this data is divided into 5 regions, based on groupings of major watersheds identified by their hydrologic unit codes (HUC). These are zipped by region, with no zipfile greater than 120mb: - North Tx: HUC1108-1114 (0.52 million address points) - DFW-East Tx: HUC1201-1203 (3.06 million address points) - Houston-SE Tx: HUC1204 (1.84 million address points) - Central Tx: HUC1205-1210 (2.96 million address points) - Rio Grande-SW Tx: HUC2111-1309 (2.96 million address points)

Additional state and county boundaries are included (Louisiana, Mississippi, Arkansas), as well as disaster-declaration status.

Compilation notes: The Texas Commission for State Emergency Communications (CSEC) provided the first 3 million address points received, in a single batch representing 213 of Texas' 254 counties. The remaining 41 counties were primarily urban areas comprising about 6.28 million addresses (totaling about 9.28 million addresses statewide). We reached the GIS data providers for these areas (see Contributors list below) through these emergency communications networks: Texas 9-1-1 Alliance, the Texas Emergency GIS Response Team (EGRT), and the Texas GIS 9-1-1 User Group. The address data was typically organized in groupings of counties called Councils of Governments (COG) or Regional Planning Commissions (RPC) or Development Councils (DC). Every county in Texas belongs to a COG, RPC or DC. We reconciled all counties' addresses to a common, very simple schema, and merged into a single geodatabase.

November 2023 updates: In 2019, TNRIS took over maintenance of the Texas Address Database, which is now a StratMap program updated annually [6]. In 2023, TNRIS also changed its name to the Texas Geographic Information Office (TxGIO). The datasets available for download below are not being updated, but are current as of the time of Hurricane Harvey.

The marine mammal habitat-based density models for the Atlantic Ocean and Gulf of Mexico currently featured in MarineCadastre.gov are outdated, and new models will be available online later in 2015. These new models are being developed by Duke University’s Marine Geospatial Ecology Lab in partnership with NASA, the NOAA Cetacean & Sound Mapping project, and the U.S. Navy. The marine mammal data layers currently in MarineCadastre.gov represent habitat-based model estimates of animal density. The model results show estimates of the average number of animals per square kilometer during a given season. Most average estimates per square kilometer feature less than 1.0 animal because marine mammals are highly mobile and often occur in large groups. An average value of 0.5 bottlenose dolphins per square kilometer during the summer could mean a number of things. For example, it could mean that one animal would be present every other day; one group of five animals would be present once in a 10-day period; one group of 50 animals would be present every 100 days; and so forth. For more information on the current models, view the “Uses” or “Publication” options under the “Uses and Metadata” button for the marine mammals data sets.

This feature layer is a collection of the private manholes in the wastewater system for the City of Round Rock, located in Williamson County, Texas. This layer is part of an original dataset provided and maintained by the City of Round Rock GIS/IT Department. The data in this layer are represented as points.A manhole is an opening to a confined space such as a shaft, utility vault, or large vessel. Manholes are often used as an access point for an underground public utility, allowing inspection, maintenance, and system upgrades. The manholes in this layer are privately owned, and not owned by the City of Round Rock.

Description: These layers contains the nonattainment and maintenance areas (counties) in Texas. It was derived from the EPA’s Greenbook. A nonattainment designation means an area has not achieved compliance with the National Ambient Air Quality Standards (NAAQS). A maintenance designation means the area was formerly in nonattainment but has monitored attainment and is currently under a maintenance plan1. The U.S. Environmental Protection Agency (EPA) established the 8-Hour ozone NAAQS in 1997 and revised it with the 2008 and 2015 standards. The 1997 ozone NAAQS was revoked in April 6, 20152, along with the classifications, so the current maintenance designation is based on the approval of a maintenance plan by EPA for the region; rather than an official reclassification. These nonattainment counties were designated by the EPA based on their air quality monitoring data. Before it was revoked, there were 17 nonattainment counties for the 1997 ozone NAAQS: 8 counties in the Houston/ Galveston area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller); and 9 counties is the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant). There are 3 maintenance counties for the 1997 ozone NAAQS in the Beaumont/Port Arthur area (Hardin, Orange, Jefferson)3. There are 18 nonattainment counties for the 2008 ozone NAAQS: 8 counties in the Houston/ Galveston area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller); and 10 counties in the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, and Wise)4. There are 16 nonattainment counties for the 2015 ozone NAAQS: 1 county in the San Antonio area (Bexar); 6 counties in the Houston/ Galveston area (Brazoria, Chamber, Fort Bend, Galveston, Harris, and Montgomery); and 9 in the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Tarrant, and Wise)5. The EPA established the NAAQS for particulate matter with a diameter of 10 micrometers or smaller (PM-10) in 1987. There is one nonattainment area for the 1987 PM-10 NAAQS: which is a portion of El Paso county6. The EPA established the NAAQS for carbon monoxide (CO) in 1971. There is one maintenance area for the 1971 CO NAAQS: which is a portion of El Paso county7. References:1.

This data layer can be used for a variety of purposes, including: the plotting of DCRP sites on maps; utilization by field personnel; and performing spatial analysis on how the sites affect their surroundings. The purpose of the Dry Cleaner Remediation Program is to oversee the cleanup of with soil and groundwater contamination caused by dry cleaning solvents from dry cleaning facilities. The goal is to assure that the public is not exposed to hazardous levels of chemicals by requiring mitigation and/or removal of the contamination to levels protective of human health and the environment.The Dry Cleaner Remediation Program (DCRP) was established by the Texas Legislature in 2003. It created the Dry Cleaning Facility Release Fund for state lead clean up of dry cleaner related contaminated sites. It also established dry cleaner facility registration requirements, fees, performance standards, distributor registration, and revenue disbursement.
