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. Managing how groundwater resources are used is key to controlling subsidence. By 1977, an extensive groundwater well-monitoring network had been established and the USGS had collected water-level data that were used to create the first published water-level altitude maps of the Chicot and Evangeline aquifers in the Houston-Galveston region. https://lnkd.in/gkwTtcAZ. The nearby hydrograph shows that when a subsidence district was created around 1976 (red line), groundwater levels in the Chicot Aquifer rose substantially. All Rights Reserved.

It is the purpose of the HGSD Regulatory Plan to establish policy in the area of groundwater regulation, permits and enforcement. Prior to 1975, the withdrawal of groundwater from the Chicot-Evangeline aquifer was unregulated, and compaction data. One of the primary concerns of subsidence in the coastal regions is flooding due to storm surges associated with hurricanes, where permanent seawater inundation and periodic storm water surge can dramatically impact property. 2019 Annual Groundwater Report Appendix A, 2019 Annual Groundwater Report Appendix B, 2019 Annual Groundwater Report Appendix C.
