Legislature authorized the establishment of the Harris-Galveston Subsidence District to regulate and Land subsidence is the gradual lowering of land-surface elevation. The Authority has entered into a Water Supply Contract with the City of Houston to obtain treated surface water from Houston. USGS measures groundwater levels in over 700 wells in an 11-county area annually in the Grant opportunities to implement projects that help reduce water use in the HGSD Regulatory Areas. The Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the . Harris County MUD 501 is within the boundaries of the Harris Galveston Subsidence District (the Subsidence District) which regulates groundwater withdrawal. In 2001, the Texas legislature created the West Harris County Regional Water Authority (the Authority) to, among other things, reduce groundwater usage in, and to provide surface water to, the western portion of Harris County and a small portion of Fort Bend County. This process is crucial to prevent buildings from flooding. region since the early 1900s.

Data were compiled and multiple hydrologic parameters were utilized to improve the understanding of the brackish resources within the study area. The RGUP originally started in 2010 as the Harris-Galveston Subsidence District (HGSD) 1999 Regulatory Plan Update, but due to its benefits to other regional groundwater regulatory agencies, the Fort Bend Subsidence District (FBSD) and the Lone Star Groundwater Conservation District (LSGCD) joined the collaborative effort in 2010.The primary benefit of collaboration between these three entities is that each of them could use the RGUP to vet their existing regulatory plans using updated population/water demand data and groundwater modeling capability, and in the case of HGSD and FBSD, investigate the physical effects of changing their existing regulatory plans to accommodate the practical realities facing their stakeholders while successfully completing the Districts mission objectives. endstream endobj 187 0 obj <>/Metadata 33 0 R/OCProperties<>/OCGs[219 0 R]>>/Outlines 37 0 R/PageLayout/SinglePage/Pages 184 0 R/StructTreeRoot 50 0 R/Type/Catalog>> endobj 188 0 obj <>/ExtGState<>/Font<>/Properties<>/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 189 0 obj <>stream Purpose: To preserve, conserve and protect Montgomery Countys groundwater supplies.

Removing water from fine-grained aquifer sediments compresses the aquifer leaving less pore space available to store water resulting . 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. The goal was to keep the region elevated by developing ways to reduce groundwater consumption.. Click here for more information about the Authority. The Lone Star GCD has studied the Gulf Coast Aquifer for a decade and confirmed the reports of many local water suppliers, which state that water levels in the countys aquifers have declined at an alarming rate as a result of deficit pumping. Now on its fifth iteration since 1976, the plan describes the different regulatory areas throughout the district, defines groundwater withdrawal limits for each area, and provides guidelines for permitting. Used by HGSD as guides in the exercise of the powers in the accomplishment of the purposes of Special Districts Code. However, there is another cause of subsidence in our area which causes the activation of surface faults (which can damage roads, houses, and buildings), loss of wetlands and . Elections Groundwater-level and compaction data are available as part of USGS data products. Further information detailing the data processing and map creation for each published regional The review of the plan includes the following steps: The initial stakeholder meeting for the joint regulatory plan review will take place May 20, 2020 and future progress meetings will be scheduled periodically throughout the project. Additionally, the US Geological Survey (USGS) has begun work on the GULF-2023 model, with an anticipated completion date in the fall of 2021. 2003: Regulatory areas divided into area A, which includes the Richmond-Rosenberg resulting in subsidence.

Since the mid 1970s, the USGS and the Harris-Galveston Subsidence District have conducted scientific investigations and subsidence monitoring for over 40 years. The accuracy of the referenced well land-surface altitude data has improved through time and the most Since 1836, groundwater withdrawals have caused about 3,200 square miles of the Houston-Galveston area to subside (or sink) more than a foot, with some areas subsiding as much as 12 to 13 feet. This dataset was created to provide resource managers, public officials . Some natural land subsidence also occurs over long periods of time, due to natural settling.
