Barton Springs Pool contains two principal infrastructure elements that address creek flow from Barton Creek. These elements are known as ‘by-pass’ features. One is the 1940’s by-pass and the other is the more robust by-pass installed in 1975. The 1940’s by-pass was decommissioned after the completion of the 1975 by-pass, but the original infrastructure remains in the pool. Due to decades of flood events impacting the flow of Barton Creek, the 1940’s by-pass infrastructure has been continually undermined. The project will seek to remove the old by-pass due to safety and environmental concerns. This project is in the demolition planning phase. City Council Districts 5 and 8

Background

Barton Springs Pool contains two principal infrastructure elements that address creek flow from Barton Creek. These elements are known as "by-pass" features. The original Barton Springs by-pass was constructed in the 1940s. A larger, redesigned by-pass was constructed in 1975, and the original was decommissioned at the completion of the newer by-pass structure. The 1975 by-pass is under the walkway on the north side of the pool area. The original by-pass was diverted via a skimmer into the newer, larger by-pass upstream of the flow from Barton Springs. The original by-pass may still be operable and continue to channel water through as designed. Since the construction of the 1975 by-pass, several flood events have occurred at Barton Springs. These flood events have caused continual undermining of the original by-pass and damages to the existing encased pipe. Recent studies performed by Watershed Protection Department (WPD) have concluded that the undermining may cause the 1940s by-pass to collapse which is a safety concern and will threaten the existing salamander habitat.

Project Description

The project proposes to remove some or all sections of the 1940s skimmer by-pass to mitigate the risk of the structure's failure and injury to users of Barton Springs Pool. The project also proposes to protect, and if possible, enhance the salamander habitat. No construction or improvements to the pool are anticipated.

Objectives

  • Remove some or all sections of the old skimmer by-pass.
  • Protect Barton Springs landscape grounds during demolition.
  • Protect salamander habitat during demolition.
  • Enhance salamander habitat if possible.
  • Enter into an agreement with WPD on monitoring of the 1975 by-pass.
