Polygons that document stream restoration projects to resolve the problems identified in the Erosion Sites https://data.austintexas.gov/Environmental/Erosion-Sites/599b-4cjg dataset.

Impervious surfaces and other artificial land cover types were manually traced from aerial imagery taken in 2021. This dataset serves various purposes, including the computation of the Drainage Charge by the Watershed Protection Department, conducting wildfire assessments, planning for emergency operations, monitoring transportation assets, and more. The city obtains new aerial imagery and impervious cover data every two years, with each capture provided as an individual dataset. There have been no updates to this dataset since its initial capture in early 2021.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk Information And supporting data used to develop the risk data. The primary risk; classificatons used are the 4-precent-annual-chance flood event, 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 UTM 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 1:12,000.

This dataset represents CEF buffers identified during the development review process since 1995. Prior to 1995, data is either unavailable or lost. CEF buffers were digitized from construction plans, environmental assessments, and City of Austin staff field observations into a versioned SDE database using ArcMap. Actual buffers size for any particular feature may be determined through a process of negotiation with land development interests, and may differ from standard dimensions stated in the Land Development Code.

100 foot buffers of stream centerlines with drainage areas of 64 acres or greeater

This is a list of nurseries and home improvement stores throughout Austin that have the Grow Green fact sheets and the Native and Adapted Landscape Plant Guides available.

This dataset entails the delineation of impervious surfaces and artificial land cover types extracted from aerial imagery captured in early 2019.

Utilization within the City of Austin

The dataset plays a pivotal role in several municipal functions, encompassing the computation of the Drainage Charge managed by the Watershed Protection Department, wildfire assessments, emergency operations planning, transportation asset monitoring, urban forest management, and more.

Data Updates

New aerial imagery and impervious cover data are acquired by the city every two years, resulting in distinct datasets for each capture. As of its initial capture in early 2019, there have been no subsequent updates to this dataset.
