Houston is sinking faster than expected!

April 14, 2022

Houston is known as the ‘Energy capital of the world.’ It is the most populous city of the Texas with 2.3 million population. The city is experiencing increase in annual average temperature since 1950. The no. of hot days has increased with 37°C and warm nights with 26°C.  The climate threats such as increase in the average temperature throughout the year, lengthening of summer, increase in energy demand and change in annual precipitation.

Land subsidence in Houston city is due to compaction of fine-grained aquifer sediments below the land surface and groundwater exploitation. Topography of the city is covered with clay soil which shrink when soil moisture evaporates lead to damaging foundation, roads, and water lines.

Houston’s Government has set resilience targets to develop 50 neighborhood plans, to plant 4.6 million new native trees, to remove all habitable structures from the floodway by 2030 and to conserve 24%of undeveloped regional lands as natural spaces by 2040 to mitigate Urban heat island effects.

Sustainable land use and zoning should be considered in designing city, streets and buildings can be orient to direct surface water in low lying areas. Implementation of innovative green stormwater infrastructure which use vegetation and nature-based solutions to reduce flooding and cool the surrounding environment.
