Subsidence is when the elevation of the ground drops slowly over time as water is pumped out and used for commercial and domestic uses. Since 1973 most of Harris County has fallen 1 foot with some areas falling as much as 5 feet. The Harris Galveston Subsidence District was created to monitor and address this problem and the rate of subsidence has been greatly reduced throughout most of the county.
