In 1975, the Texas Legislature established the Harris-Galveston Subsidence District to safeguard the lives and property of residents in Harris and Galveston counties from the devastating effects of subsidence. Since then, the District has successfully paved the way to achieve this mission through its internationally recognized regulatory planning, advanced science and research, dedication to regional collaboration, and award-winning water conservation programs.

On September 18, 2025, the District held a reception to celebrate this monumental achievement, featuring delicious bites, nostalgia, networking, and a speaking program highlighting progress over the past five decades. Our deepest gratitude to those who joined our celebration and to those who have supported the District throughout these 50 years!
