A concrete plug was installed in the pipe from Dog Beach up through the dam, providing a long-term solution that effectively eliminates the risk of recurrence. Barton Springs remained closed for a few additional days to allow the concrete to fully cure. During that time, PARD also took the opportunity to re-sod areas of the south side bank and carried out routine multi-day tree maintenance. 10 Barton Spring Pool Reopens September 19, 2024 • Four weeks after discovering a hole in the aging infrastructure, Barton Springs was able to reopen to the public, providing a safe and guarded place for the public to swim. • This repair was made possible through the collaborative efforts of over 100 City of Austin staff members from multiple departments. We take great pride in our work to restore operations swiftly while ensuring the highest level of care for this cherished place and its visitors. 11 Angela Means Liana Kallivoka Lucas Massie Jodi Jay Suzanne Piper Rey Hernandez Lindsey Machamer Juan Bustillos Nate Thayer Charles Vaclavik Hayden Doskocil Domingo Espinosa Trevor Hollen Alberto Gonzalez Anthony Alvarez Ashley Wells Aaron Levine DeAndre Cain Sarah Donaldson Lily Yepez Sean McDonald PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD PARD Milton Hein JC Shumake PARD Dylan Broussard PARD Catherine Carradine PARD Helena Finos PARD August Fye PARD Gunnar Gentry PARD Justin Gronquist PARD Joel Guerrero PARD Andrew Hernandez PARD James Meshbane PARD Alisha Miles PARD Nina Moin PARD Aliyah Morales-Serrano PARD Christopher Pitts PARD Riley Quigley PARD Steven Ramos PARD Rowan Rodriguez PARD Bella Salem PARD Stephanie Simpkins-Marshall PARD Isaac Sprouse PARD PARD Nicholas Stoop PARD Michael Valdez PARD PARD PARD PARD PARD PARD Ethan Wood Izak Zaplatar David Papke Leann Ishcomer Ann Pfund Cameron Neagil PARD PARD PARD CPIO CPIO CPIO CPIO CPIO WPD WPD WPD WPD WPD WPD WPD WPD WPD WPD WPD WPD WPD WPD WPD AW AW Betty Pu Dan Manco Raquel Dadomo Jessica King Jenny LaCoste-Caputo Memi Cardenas Rachel Freeman Gisel Adame Ramesh Swaminathan Matt Westbrook Sara Donnelson Nathan Bendik Michael Markowski Radmon Rice Eric Loucs Charlie Hartman Helen Hartman Donald Heisch Stephanie Lott Becca Villareal Susan Berkenmayer Patrick Reister Susan Garnett Manual Macias Zechariah Garza 12 Thank You!! Questions? 13
