Sinking situation of subsidence in Houston, Gulf Coast EXECUTIVE SUMMARY: The Fort Bend Subsidence District (FBSD) revised its District Regulatory Plan (DRP) in 2013 based on population and water demand projections, which were developed as part of a Regional Groundwater Update Project (RGUP) completed in 2013. In reaction to the subsidence issues across the Houston-Galveston region, the Texas Legislature established the first subsidence district in 1975 to reduce or minimize further groundwater subsidence in their area. When we pump large amounts of water from the aquifers beneath us, we pull water out of the many layers of clay, which causes the clay to compact, lowering the elevation of the land above. Providing analysis of accurate and up to date predictions on water usage; the enforcement of real disincentives to those who rely too heavily on groundwater; and an unwavering commitment to practicing and promoting water conservation. Purpose: To manage groundwater withdrawal and enforce groundwater regulation throughout Harris and Galveston counties, in hopes of preventing the land subsidence that leads to increased flooding. Harris-Galveston Subsidence District | The Texas Alliance of Extensometers and Subsidence. Though subsidence rates are moderate in Fort Bend county, the continued heavy dependence of groundwater use may result in increased subsidence and associated impacts such as flooding and infrastructure damage.
