Stormwater Controls

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

Strategic Direction 2023 (SD23) Measure HE.D.3 reports the number and percentage of creeks and lakes in good or excellent health. This measure is calculated every two years using the monitoring data from the Watershed Protection Department's Environmental Integrity Index (EII) and Austin Lakes Index (ALI) programs. These programs monitor and assess the chemical, biological, and physical integrity of Austin’s creeks and lakes.

Note: Due to software limitations, the scores for one biennial reporting period (e.g., FY2013/2014) are repeated twice in the dataset in order to enable the creation of data visualizations that require annual reporting.

The Watershed Protection Department has been distributing engineering assessments and scientific reports using the text-driven Watershed Publications Search tool. [http://www.austintexas.gov/watershed_protection/publications/default.cfm] The idea is to extend that tool by providing geographic context. This dataset will change. Links to applications using the tool will be updated when they go live.

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.

Strategic Direction 2023 (SD23) Measure HE.E.5.a reports the number and percentage of buildings, roadways, and properties whose exposure to high flooding risk have decreased due to City efforts. Flood risk can occur during rain events when creeks overflow their banks (creek flooding) or when the capacity of older storm drains and small channels is overwhelmed (local flooding). The Watershed Protection Department helps reduce flood risk through the implementation of structural solutions (e.g., detention ponds, low water crossing upgrades, floodwalls, flow diversion, storm drain improvements) and non-structural solutions (e.g., property acquisition or "buyouts" of properties with severe flood risk, permanent road closures).

Areas that are within City of Austin publicly-owned land that have been identfied as Grow Zones in a collaboration between Parks and Recreation and Watershed Protection Departments. Contains primary contact information, acreage, watershed designations and a description of the prescribed maintenance regime that will enable restoration of healthy ecological function.

The Manhole REFDOC table should be used in conjunction with the Manhole feature class https://data.austintexas.gov/dataset/Manhole/38q2-v8xr with a join on the DRAINAGE_ID.
