Last week, some of our Board of Directors and District Staff visited areas that have historically been affected by subsidence and toured important projects that have been implemented to prevent further subsidence in the Houston area. People who live in the lower lying coastal areas (i.e., lower elevations and flatter topography) have much more reason to be concerned with subsidence than those who reside further inland in areas of higher elevations with more topographic relief. 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 public hearing fulfills the requirements of the Districts enabling legislation, which states that the Board of Directors shall hold a public hearing to take testimony concerning the effects of groundwater withdrawals on the subsidence of land within the District during the preceding year.
