All Rights Reserved. reduce groundwater withdrawals in Harris and Galveston Counties. Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. 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. Grant opportunities to implement projects that help reduce water use in the HGSD Regulatory Areas. the Houston-Galveston Region, Texas. 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. 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. The goal was to keep the region elevated by developing ways to reduce groundwater consumption.. Since the mid 1970s, the USGS and the Harris-Galveston Subsidence District have conducted scientific investigations and subsidence monitoring for over 40 years. The Authority has developed a groundwater reduction plan (GRP) and obtained Subsidence District approval of its GRP. 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. Water-level altitude is calculated at each well by subtracting the water-level measurement (depth to

Alters the flow of creeks and bayous which may increase the frequency and severity of flooding. Numerous subsurface faults have been documented beneath the Houston metropolitan area at depths of 3,200 to 13,000 feet. This process is crucial to prevent buildings from flooding. 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. The data is temporarily stored in an on-site monitor and periodically uploaded to computers at the Harris Galveston Subsidence District. V(&xH:1dxB0"5Cu)edL9x2Z~Q`&1R`oC1NTEGxfP8QMiuy6T8-%HI

The district proactively works with its groundwater users to address issues such as how to most efficiently use groundwater, control and prevent waste, control and prevent subsidence, and address drought conditions. The Harris-Galveston Subsidence District maintains GPS monitoring stations in Harris, Galveston, Fort Bend and surrounding counties. 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. The District Science and Research Plan represents the strategic direction for science and research conducted or supported by the Fort Bend Subsidence District (FBSD) and, as such, is an essential component of the Districts regulatory planning process. extensometer stations in the 11-county area.

Managing how groundwater resources are used is key to controlling subsidence. 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. Report Street Light Outage Land subsidence is the gradual lowering of land-surface elevation. Visit smarteraboutwater.org for water conservation resources to help homeowners, businesses, and the community. The cumulative compaction in the Chicot and Evangeline aquifers are measured at 13 extensometer stations in the 11-county area. The District has taken a reasonable approach to groundwater regulation in order to minimize subsidence within its regulatory areas. 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. The cumulative compaction in the Chicot-Evangeline undifferentiated aquifer is measured at 13

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. Used by HGSD as guides in the exercise of the powers in the accomplishment of the purposes of Special Districts Code. 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. Created by the Texas Legislature in 1975 to stop further subsidence in the Houston-Galveston region. Then, use either Enter or Space key to open the selected district. This study, spawned from their original research that showed subsidence in southern Montgomery County was caused by exploitation of the Jasper aquifer, will investigate the combined effects of climate changes on coastal subsidence to enhance understanding of the deformation process.
