Most compaction that occurs as a result of groundwater withdrawals is irreversible; even if groundwater (3) "District" means the Harris-Galveston Subsidence District. 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. 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.

Legislature authorized the establishment of the Harris-Galveston Subsidence District to regulate and Harris-Galveston Subsidence District Joins the Winners' Circle. These units operate in conjunction with the two that have been monitoring land levels in Montgomery County for more than 10 years. . This site is a publicly available, searchable, online database of water information. The Harris-Galveston Subsidence District is a special purpose district created by the Texas Legislature in 1975 to regulate groundwater withdrawal throughout Harris and Galveston counties in order to prevent land subsidence. Subsidence is known to have occurred in the southern part of Montgomery County based on monitoring and long-term surveying of land surface. This effort has published aquifer levels and subsidence data since 1975 and is a great example of what can be accomplished through sustained collaboration between, city, county, regional, and federal partners.

In this chapter: (1)AA"Agricultural crop": (A)AAmeans food or fiber commodities that are grown for resale or commercial purposes and that are to be used for food, clothing, or animal feed; and (4) "Groundwater" means water located beneath the earth's surface. Now Hiring! Subsidence Risk Assessment and Regulatory Considerations for the Brackish Jasper Aquifer. The USGS has a long history of working with HGSD and other entities in the Houston region. Land subsidence is the gradual lowering of land-surface elevation. Trash available to store water resulting in the lowering (sinking or settling) of the land-surface. HGSD lies within the boundaries of Groundwater Management Area 14 (GMA 14). HGSD conducts regulatory planning on a regular basis to confirm that adopted regulations have reduced subsidence rates. The reduction in pumpage has resulted in the increase of water- level in the aquifer system in those areas and a reduction in subsidence rates. each regional water-level altitude map. o35d8\,=R/.Y2xTE@;jj?4/gh?D$U2;MrpF&tMF6h-|l-:nSzC~ ER5knSP" zXyY/mY|{mm}x"S8K~"UILrD> This report, prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Coastal Subsidence District, documents and refines the locations of principal faults mapped in the Houston, Texas, metropolitan area in previous studies. The Deputy General Manager serves as the Chief Operating Officer of the Fort Bend Subsidence District and provides the day-to-day leadership, management and vision necessary to ensure that the District has the proper operational controls, administrative and reporting procedures, and people systems in place to effectively complete . 4Rw,De@5hfbHY`b`H=n We I$@g|0 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. HARRIS-GALVESTON SUBSIDENCE DISTRICT SUBCHAPTER A. This is accomplished through the careful regulation of groundwater withdrawals, working in collaboration with surface water suppliers. In order to evaluate the performance of the projection methodology which informed the 2013 DRP, the short-term projections from the RGUP have been evaluated against recent estimates of population and water demand from multiple sources at various geographic scales. Evaluation of Projected Population and Water Demands in Fort Bend County. 2003: Regulatory areas divided into area A, which includes the Richmond-Rosenberg On our last stop, we toured theCity of Houstons Northeast Water Purification Plant Expansion. Population projections were developed at the census block level for each decade from 2010 to 2070 using the 2010 U.S. Census as a population baseline. The Harris-Galveston Subsidence District is a special purpose district created by the Texas Legislature in 1975 to regulate groundwater withdrawal throughout Harris and Galveston counties in order to prevent land subsidence. Explore Groundwater-Level and Compaction Data in the Chicot, Evangeline and Jasper Aquifers. Since it is not a GCD, HGSD participates in the activities of GMA 14 as an inter-local participant. In cooperation with % The model will simulate the impacts of groundwater use on aquifer water levels and land subsidence throughout the region and will be used to evaluate regulatory scenarios of interest to both subsidence districts. 1992: Regulatory areas redivided into 7 areas. Evaluation of projected population and future water demands, Development of subsidence models to simulate future subsidence based on projected water demands, Measurement of annual water-level to show the impact of conversion requirements on the water-level in the aquifer, Assessment of alternative water supplies including brackish groundwater use and aquifer storage and recovery.

Harris County Sheriffs Office The RGUP was jointly supported by the Harris-Galveston Subsidence District, the Fort Bend Subsidence District, and the Lone Star Groundwater Conservation District. The District was created to provide for the regulation of groundwater withdrawal. Since the mid 1970's, the USGS and the Harris-Galveston Subsidence District have conducted scientific investigations and subsidence monitoring for over 40 years. These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers.
