According to the Harris-Galveston Subsidence District, some parts of Harris County have sunk 10 feet since 1906. The problem is also happening rapidly now in some areas such as in the Greater Greenspoint area, which has sunk about 2 feet in the last decade alone, according to United States Geological Survey (USGS) data. Mark Kasmarek, a hydrogeologist for more than 30 years with the USGS says, “When you lose that much, it makes an area prone to floods when they weren’t historically.”
The Harris-Galveston Subsidence District, created in 1975, has been effective at slowing the subsidence rates in the areas it regulates. Instead of losing a foot every 10 years, many areas saw that rate cut by a little more than two-thirds. However, more needs to be done to fix the problem because once an area sinks it is very hard to build it back up and the occurrence of flooding increases. That is why the Committee and I will look into both statewide and local solutions to better educate the public, increase groundwater conservation, converge to alternative sources of water, and build additional reservoirs.
I will continue to keep you updated on this important issue as the County Affairs Committee studies it during the interim. The Committee’s next hearing will be in Corpus Christi on Tuesday, June 6th. The Committee will once again discuss Hurricane Harvey and the damage it caused particularly by wind damage to the coastal bend region.
According to the HGSD, from 1978 to 2000, as much as 5 feet of subsidence has been measured in northwest Harris County. This is demonstrated in the map above.
