The Battle Bend Park Capital Improvement Project will create a new playing field within Battle Bend Park that doubles as a stormwater control measure to capture and treat runoff from the nearby commercial and industrial area during rain events. The stormwater control measure will filter this water through a sandy soil media that removes pollutants before the water enters Williamson Creek. During dry weather, the level, turf-covered field will provide a playing surface for informal recreation.
This project will stabilize and rehabilitate approximately 1800 linear feet of a degraded, incised tributary to Williamson Creek in the Indian Hills Subdivision. Rehabilitation will include use of natural materials, native vegetation, plus removal of trash and debris.
Watershed Protection is working on repairs to Bluff Bend Drive. When the repairs are complete, the road will be rebuilt over the creek with a sidewalk. The new road will be much less likely to flood than previously.
The Boggy Creek restoration project is a two part project designed to preserve parklands, improve aesthetics, stem any erosion threat to Rosewood Avenue, and to maintain storm sewer outlet infrastructure. The first part of the project is just upstream of Rosewood Avenue, where banks will be stabilized and erosion repaired. The second part of the project is upstream of the pedestrian bridge near Walnut Avenue, where erosion is threatening to damage a walking trail and creating trash accumulation.
The Brentwood neighborhood was developed before the City adopted the current stormwater code. Erosion in the area currently threatens streets, utilities, and houses. This study will generate feasible, cost-effective solutions to flooding and stream erosion and incorporate water quality solutions for stormwater runoff.
There is significant erosion along Country Club Creek in the Roy G. Guerrero Park. The erosion is quickly getting worse. It has already made portions of the hike and bike trail impassible and is threatening the nearby ballfields.
Watershed Protection has made significant improvements to the storm drain system in the Dawson Neighborhood, but there's more work needed to help with flooding of houses, yards and streets.
To help protect the endangered Barton Springs and Austin Blind Salamanders, we are recreating a stream that once flowed from Eliza Spring, one of the four springs in Zilker Park that are collectively known as Barton Springs. Eliza Spring is the sunken, fenced off amphitheater area by the Zilker Zephyr.
Historically, shorelines were stabilized with vertical walls called bulkheads, which can be bad for the lake because they reflect wave action and degrade shoreline habitat. This project will retire the old failing wooden bulkhead located between the boat ramps at Emma Long Metro Park and replace it with an environmentally friendly design.
Decades of urbanization in the Little Walnut Creek watershed have altered the stream flow of Little Walnut Creek causing significant erosion along the bank. The creek bank is widening, threatening large trees, power poles, and property, and exposing bedrock and wastewater lines.
This project will divert floodwater to a proposed tunnel. The tunnel will run under Mearns Meadow Blvd., and reduce the frequency and depth of flooding for houses and roads between Metric Boulevard and Rutland Drive near Little Walnut Creek.
This project will stabilize approximately 300 feet of eroding streambank along Buttermilk Creek. The project area begins near the intersection of Hemingway Street and Old Town Drive and ends approximately 300 feet downstream. The design includes stabilizing the streambank using drilled concrete piers with a concrete retaining wall, combined with natural limestone boulders, mechanically stabilized earth structures and native plants.
This project aims to reduce the flooding of houses and yards near Meredith Street in the Tarrytown neighborhood with an updated storm drain system. The project will also help improve water quality and erosion issues.
The Watershed Protection Department is studying flooding in the area around 183 and Jollyville Road. The study will result in a preliminary engineering report that evaluates possible ways to reduce flooding in three specific problem areas.
Watershed Protection is planning a project to reduce flooding in the Oak Park and Oak Acres subdivisions.
As a public safety measure, the Watershed Protection Department is buying out flood-prone homes near William Cannon Drive and South Pleasant Valley Road.
The Onion Creek Flood Study has two main goals: to update the floodplain maps for Onion Creek and to evaluate options to reduce flooding in the Onion Creek Neighborhood.
Four ponds maintained by the City of Austin in the Sendera and Circle C neighborhoods are in need of repair. These ponds were designed with clay liners that have proved inadequate. Their deterioration could lead to polluted stormwater entering the aquifer that feeds Barton Springs. This project will replace the clay liners with geotextile fabric. It will also improve berms and irrigation systems around the ponds. When construction is complete, the pond edges will be revegetated with native wetland plants.
The Watershed Protection Department is constructing a streambank stabilization project to protect homes and property from ongoing erosion damage. The project will use natural limestone boulders that will connect with existing streambank protection projects upstream and downstream of the erosion.
This feasibility study will assess possible solutions to flooding along Shoal Creek between 15th Street and Lady Bird Lake.
This project provides ongoing protection against erosion, improves water quality in Shoal Creek and has restored native vegetation along the creek.
Tannehill Branch Creek in Givens Park suffers from erosion that causes water quality problems and threatens large trees, a picnic table, and parkland. This project will stabilize the bank of Tannehill Branch downstream of the pavilion. It will also construct a raingarden near Oak Springs Drive to capture and treat parking lot runoff.
Austin and other communities within Upper Brushy Creek Water Control and Improvement District are updating the floodplain maps for Upper Brusy Creek, including portions of Lake, Rattan and South Brushy Creeks.
For years, Austin’s Waller Creek has been beset by severe flooding, erosion and water quality problems. When completed, the Waller Creek Tunnel will remove over 28 acres of downtown land from the 100-year floodplain.
This project restored approximately 1,100 feet of Waller Creek within Eastwoods Park. Most visibly, the project restored and stabilized the creek’s severely eroding stream banks.
The Watershed Protection Department and the Union Pacific Railroad are working in cooperation on this two-phase project to help with flooding along Whispering Valley Road and in the West Cow Path area.
Watershed Protection is working on a two-phase, flood-related project along the middle portion of Williamson Creek. The project area includes approximately 250 properties near Stassney Lane between the railroad track and South Congress.
