This dataset was created by the Transportation Planning and Programming (TPP) Division of the Texas Department of Transportation (TxDOT) for planning and asset inventory purposes, as well as for visualization and general mapping. County boundaries were digitized by TxDOT using USGS quad maps, and converted to line features using the Feature to Line tool. This dataset depicts a generalized coastline.Update Frequency: As NeededSource: Texas General Land OfficeSecurity Level: PublicOwned by TxDOT: FalseRelated LinksData Dictionary PDF [Generated 2025/03/14]

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12000.

This layer represents the jurisdiction and regulatory boundaries of the City of Austin.

In 1992, four endangered species habitat and management zones in the Austin region were delineated for the USFWS by George Veni and Associates. Those zones were defined as:

Zone 1: areas known to contain endangered cave faunaZone 2: areas having a high probability of suitable habitat for endangered or other endemic invertebrate cave fauna (refined now to only endangered cave fauna)Zone 3: areas that probably do not contain endangered cave fauna; andZone 4: areas which do not contain endangered cave fauna.Zone boundaries were updated in 2007 to reflect more recent studies of cave and karst development and the most current biological information available on the distribution of listed and non-listed troglobite species. For more information on listed karst invertebrates in Texas, see https://www.fws.gov/southwest/es/AustinTexas/ESA_Sp_KarstInverts.html.
