Regulatory Plan
The Harris-Galveston Subsidence District’s Regulatory Plan was developed with the overall goal of reducing groundwater withdrawal to a level that no longer contributes to further subsidence within the District. The purpose and intent of the Regulatory Plan are to establish policy in the areas of groundwater regulation, permitting, and enforcement, and to define the HGSD Regulatory Areas and the regulatory requirements for each area.
The Regulatory Plan is regularly reviewed using the best available data to ensure the plan’s effectiveness in preventing subsidence. The most recent plan review was completed in 2025.
The current HGSD Regulatory Plan was approved on January 9, 2013, and amended on April 14, 2021.
