They have successfully slowed-down land subsidence, decreased flood risks, and overall maintained the viability of the area.

For keyboard navigation: First, use Arrow Keys to navigate up and down the districts. SMU is developing subsidence maps from 1992 to 2023 by integrating data obtained from multi-temporal Interferometric Synthetic Aperture Radar (InSAR), a remote sensing technique using data collected from orbiting satellites, to quantitatively evaluate subsidence over specific periods of time across the region. When we pump large amounts of groundwater from the aquifers beneath us, we pull water out of the many layers of clay, which can cause the clay to compact. resulting in subsidence. % reduce groundwater withdrawals in Harris and Galveston Counties. Alternative water sources, like treated surface water, prevents excessive groundwater pumping, thereby minimizing subsidence. HGSD is divided into three regulatory areas stretching from High Island and Galveston upwards to Hempstead, TX. Disrupts collector drains and irrigation ditches.
