Harris-Galveston Subsidence District and West Harris County Regional 1045, 1989 Tex. %PDF-1.3 Since it is not a GCD, HGSD participates in the activities of GMA 14 as an inter-local participant. 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. On our last stop, we toured theCity of Houstons Northeast Water Purification Plant Expansion. 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. Trash This is because in addition to sinking land elevations, subsidence contributes to flooding, inundation, or overflow of areas within the district, including rising waters resulting from storms or hurricanes. 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. The Houston area's two subsidence districts the Harris-Galveston Subsidence District, HGSD, and the Fort Bend Subsidence District have worked to monitor subsidence and mitigate it through a variety of water management efforts. endobj Since 2019, the Subsidence District has sponsored research conducted by Southern Methodist University (SMU) that utilizes a novel methodology to evaluate land-surface deformation (subsidence) in the region. Land subsidence is the gradual lowering of land-surface elevation. 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. The accuracy of the referenced well land-surface altitude data has improved through time and the most compaction data. Subsidence Lone Star Groundwater Conservation District The network, initiated in 1994, currently extends across the Houston-Galveston region, across Harris, Fort Bend and surrounding counties, in an effort to represent the breadth and scope of subsidence in the region. in the Houston-Galveston region to provide for the regulation of groundwater withdrawals in areas within For keyboard navigation: First, use Arrow Keys to navigate up and down the districts.

Removing water from fine-grained aquifer sediments compresses the aquifer leaving less pore space available to store water resulting . Extensometers and Subsidence - San Jacinto River Authority 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. When we pump large amounts of groundwater from the aquifers beneath us, we pull water out of the many layers of clay, which can cause the clay to compact. The goal was to keep the region elevated by developing ways to reduce groundwater consumption.. The Houston area's two subsidence districts the Harris-Galveston Subsidence District, HGSD, and the Fort Bend Subsidence District have worked to monitor subsidence and mitigate it through a variety of water management efforts. In the event of an emergency, please dial 9-1-1. The Harris-Galveston Subsidence District, created in 1975, was the first of these districts.
