Data collected to assess water quality conditions in the natural creeks, aquifers and lakes in the Austin area. This is raw data, provided directly from our Water Resources Monitoring database (WRM) and should be considered provisional. Data may or may not have been reviewed by project staff. A map of site locations can be found by searching for LOCATION.WRM_SAMPLE_SITES; you may then use those WRM_SITE_IDs to filter in this dataset using the field SAMPLE_SITE_NO.

This watershed boundary consists of modeled lines and edited lines based on site plans and field investigations.

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.

A rain garden is a low area that absorbs and filters rain water runoff that comes from roofs, sidewalks, and driveways. Rain runs off the hard surfaces, collects in the shallow depression, and slowly soaks into the soil. They are usually planted with colorful native plants and grasses. Every little bit helps to conserve water. Currently we are tracking rain garden bioswale, cistern, and green roofs.

Spring critical environmental features (CEFs) were digitized from construction plans, environmental assessments and City of Austin staff review and field observations.

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 is the official list of watersheds for the Drainage Criteria Manual in the City of Austin and whether or not a watershed generally participates in the Regional Stormwater Management Program. For more information about the RSMP visit our website: http://austintexas.gov/RSMP

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.
