2001 Phase 1 Watersheds Report Volume 1
(City of Austin, 2001) Heitz, Michael J.; Hamilton, Jody
EXECUTIVE SUMMARY: The mission of the Watershed Protection Department (WPD) is to reduce the impact of flooding, erosion and water pollution on our community in order to protect lives, property and the environment. To accomplish this mission, WPD completed Phase I of a Watershed Protection Master Plan to better prioritize service needs and refine program direction. The Master Plan inventories existing watershed problems and gauges the impact of future urbanization in seventeen (17) watersheds - including all of the urban watersheds and five surrounding non-urban watersheds: Blunn (BLU); Boggy (BOG); Buttermilk (BMK); East Bouldin (EBO); Fort Branch (FOR); Harper's Branch (HRP); Johnson (JOH); Little Walnut (L W A); Shoal (SHL); Tannehill (TAN); Waller (WLR); West Bouldin (WBO); Barton (BAR); Bull (BUL); Country Club (CNT); Walnut (WLN); Williamson (WMS) Phase I studies helped to locate and prioritize problem areas where watershed protection goals and objectives are not currently being met or are not expected to be met in the future. These studies are categorized by mission as creek flooding, localized flooding, streambank erosion and water quality degradation. Integrated problem areas were determined by overlaying the results of the individual mission studies to identify areas of concurrent flooding, erosion and water quality problems. Integrated problem areas demonstrate an increased need for multi-purpose solutions. These studies determined that watershed problems are widespread and will worsen if corrective action is not taken. Creek flooding poses a recurring citywide risk to public safety and property. For example, a relatively small 2-year storm creates structure flooding in 14 of the 17 Phase I watersheds. Localized flooding also threatens property across the City due to undersized, deteriorated, clogged or inadequate storm drain systems. Over 4000 localized flooding complaints have been logged over the last ten years. New erosion data identifies numerous existing threats to property with nearly 500 sites currently threatened. Increased storm flows from urban development have accelerated streambank erosion, leading to enlarged and unstable creek channels. Water quality studies document the fact that urbanization has led to the degradation of our urban creeks and receiving waters. Future development is predicted to continue the trend of degrading habitat and creek biology and increasing pollutant levels in local surface waters. The Master Plan identifies opportunities for optimizing existing resources through improved prioritization, mission integration and a renewed commitment to the use of environmentally responsible, cost-effective and sustainable solutions. Problem priorities were established based on the severity of the identified problem at each location and the number and type of affected community resources (such as homes, roadways and receiving waters).

A Sustainable Assessment of the Codes and Plans for South Shore Central of Austin’s Lady Bird Lake
(City of Austin, 2012) City of Austin Planning and Development Review
The City of Austin has recognized that Lady Bird Lake (formerly named Town Lake) is a precious recreational resource in the heart of the urban core, which could be quickly overwhelmed if development along its shores is not carefully planned and regulated to provide a balance between accommodating growth in the urban core and preserving the character of the lakefront. The adoption of the 1985 Town Lake Corridor Study established foundational policies which were codified with the 1986 Waterfront Overlay Combining District (WOCD) ordinance. The ordinance established fifteen sub-districts (now sixteen sub-districts) within the overlay in order to calibrate the code to various locations along the 5.4 mile -long town lake corridor. The overall purpose of the ordinance was established “. . . to provide a more harmonious interaction and transition between urban development and the parkland and shoreline . . .” In 2007 the City Council appointed a Waterfront Overlay Taskforce to review the adequacy of the current waterfront ordinance in light of changes that had been made to the original ordinance over the years and to increasing development pressure along the shoreline. The Waterfront Task Force Report, 2008, made several recommendations, including the re-establishment of a Waterfront Planning Advisory Board (WPAB) with responsibilities that include recommending potential changes to the Waterfront Overlay Combining District ordinance, with particular instructions to develop bonus provisions that create clear, predictable methods for increasing development entitlements in exchange for clear, predictable community benefits, and to develop improved design standards. The WPAB has conducted this work since its appointment two years ago, but has had to carry out this task with limited support resources and without the benefit of consultant assistance The SDAT will provide an outside, professional review and assessment of the WPAB’s work to date and assist with recommendations for moving forward. Additionally, the SDAT process will help convene local resources and engage stakeholders to inform and assist with the work. In order to sharply focus the review and assessment process, the SDAT study will concentrate on one of the sub-districts of the Waterfront Overlay – South Shore Central – which is arguably the area along the waterfront most likely to face potential redevelopment prospects, and the adjacent sub-districts to the west and east which, respectively, introduce a major park land (Auditorium Shores) and an area with commercial transitioning to residential uses (Travis Heights). The South Shore Central sub-district is also adjacent to established neighborhoods. This area concentrates the issues of how to promote urban excellence while maintaining, enhancing, and connecting to parkland and neighborhoods.
Action Plan Items Related to EII Site Scores - Fiscal Year 2005
(City of Austin Watershed Protection & Development Review Department, 2005) Turner, Martha; Herrington, Chris
The Environmental Integrity Index (EII) was used to identify sites with at least a 13% decrease in environmental health in recent years. City of Austin teams with the potential to reverse the recent degradation in five problem areas, aquatic life, habitat, nutrients plus bacteria, nutrients alone, and litter, through structural and non-structural BMPs were identified. Program areas or teams addressing these areas are the surface water evaluation team, masterplan committee, community education, Austin Clean Water Program, and Keep Austin Beautiful programs. Primary and secondary site lists are provided for each of the teams.
Action Plan Items Related to EII Site Scores - Fiscal Year 2006
(City of Austin Watershed Protection Department, 2006) Herrington, Chris
The Environmental Integrity Index (EII) was used to identify creek reaches with at least a 13% decrease in environmental health in using data collected in 2006 compared to initial conditions sampled in 1996 (phase I watersheds). City of Austin teams with the potential to reverse the recent degradation in five problem areas (aquatic life, habitat, nutrients plus bacteria, nutrients alone, and litter) through structural and non-structural BMPs were identified. Primary and secondary problem reach lists are provided for the teams.
Action Plan Items Related to EII Site Scores - Fiscal Year 2009
(City of Austin Watershed Protection Department, 2009) Herrington, Chris
The Environmental Integrity Index (EII) was used to identify creek reaches with at least a 13% decrease in environmental health in using data collected in 2009 compared to initial conditions sampled from 1996-1999. City of Austin programs with the potential to reverse the recent degradation in five problem areas (aquatic life, habitat, nutrients plus bacteria, nutrients alone, and litter) through structural and non-structural BMPs were identified. Primary and secondary problem reach lists are provided for these programs. There was a sharp increase in the number of sites with litter problems. No watershed yielded a significant decline in overall EII score, and three watersheds yielded a significant improvement.
