Permit Controls

The City of Galveston is authorized by the Texas Commission on Environmental Quality to discharge stormwater from its municipal separate storm sewer system (MS4) under the Texas Pollutant Discharge Elimination System (TPDES) permit number TXR040312.

The permit requires the city to prepare and implement a Stormwater Management Program (SWMP) that, at a minimum, consists of addressing six general control measures for stormwater runoff throughout the city:

  • Construction Site Stormwater Runoff Control
  • Illicit Discharge Detection and Elimination
  • Pollution Prevention and Good Housekeeping for Municipal Operations
  • Post-construction Stormwater Management in New Development and Significant Redevelopment
  • Public Education and Outreach on Stormwater Impacts
  • Public Involvement / Participation


Each of these control measures includes programs, practices and tasks that address stormwater runoff as well as goals for making progress toward reducing stormwater pollution from the city's MS4 to the maximum extent practicable.

The SWMP is available for public review at the city's Public Works Department office at:

823 Rosenberg Street
Room 205
Galveston, TX 77553


This section illustrates some of the programs that the city is undertaking to address stormwater runoff and how citizens of Galveston can help the city meet its goals and permit requirements.
