Description: Spring critical environmental features (CEFs) were digitized from construction plans, environmental assessments and City of Austin staff review and field observations.
Description: This dataset represents wetland CEFs identified during the development review process since 1995. Prior to 1995, data is either unavailable or lost.Wetland CEFs were digitized from construction plans, environmental assessments, and City of Austin staff field observations. Features were digitized into a versioned SDE database in ArcMap. Wetland delineation may be determined through a process of negotiation with land development interests and generally reflect the most protective arrangement that could be obtained. Additionally, “fringe wetlands” were drawn using a standard 2’ width on either side of a waterway.

Description: This dataset represents Rock Outcrop Critical Environmental Features (CEFs) identified during the development review process since 1995. Prior to 1995, data is either unavailable or lost. Rock Outcrop CEFs were digitized from construction plans, environmental assessments, and City of Austin staff field observations into a versioned SDE database using ArcMap.
Description: Combination of stream centerlines created from aerial orthophotography, planimetrics based on LIDAR data "Hydro_L" (a non continuous stream) and construction plans which has been updated and edited to be a continuous stream. Creeks_line_mains is the maintenance version of this layer. One item in the "Fea_Code" attribute domain has been renamed from "Concrete lined open channel" to "altered channel" and an additional domain descriptor has been added called "Altered channel (roadside)". The "Comments" field is used to further define an altered channel's sub-type as "Concrete lined". Features previously labeled as concrete lined in the "Fea-Code" field are identified as such in the "Comments" field. Identifying altered channels (roadsides) will be on an ongoing basis.
Description: 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.

Description: This feature represents the locations of landfills in and around the City of Austin.
Copyright Text: The dataset was derived from a combination of sources including; "Landfills in the Vicinity of Austin,Texas". Prepared by Undergound Resource Management, Inc. CAPCOG, & TCEQ. Additional work was done by research from the City of Austin.
Description: The perimeter was made due to the Cities Land Development Code Requiring Site plans to be a certain distance from a landfill to meet requirements for development. The landfills perimeter layer represents the landfills where exact boundaries of the landfill are known. Those landfills with known perimeters were given a smaller buffer distance (200') for the creation of the landfills_buffer layer.

Description: This layer represents the buffered geography around the known landfills in and around the City of Austin, Texas. Due to the uncertainty of the boundaries of the landfills; the buffers are used to regulate development in close proximity to the landfills. Areas of known landfill boundaries utilize the 200' buffer. Areas where general knowledge of the landfill location is known utilize a 1500' buffer.

Description: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

Description: This layer is for ETJ and includes observation points buffered by 50 meters, and restricted to the 5-mile ETJ only. Habitat layer includes all three federally protected salamander species that live in and around Austin: Barton Springs salamanders (Eurycea sosorum), Austin Blind salamanders (Eurycea waterlooensis), and Jollyville Plateau Salamanders (Eurycea tonkawae).
