Municipal Separate Storm Sewer System (MS4) Stormwater Management Program

Stormwater Management in New Braunfels
In order to manage stormwater pollution and comply with Texas Commission on Environmental Quality (TCEQ) MS4 permit requirements, the City of New Braunfels has developed a Storm Water Management Program (SWMP). The SWMP outlines programs and Best Management Practices (BMPs) the City will implement in order to minimize pollution associated with stormwater runoff. The City's Stormwater Management Program plan can be viewed via the link below:

The City is currently implementing the following programs to minimize pollutants from reaching our waterways:

  • Public Education and Outreach: The City of New Braunfels implements a public education program to inform the community about the impact of stormwater discharges on water quality, hazards related to illegal discharges & dumping, improper disposal of waste, & steps that the public can take to reduce pollutants in stormwater. The City will hold events to involve the community in stormwater planning and education efforts.
  • Illicit Discharge Detection and Elimination: The City of New Braunfels implements and enforces a program to detect and eliminate illicit discharges to the storm drain system and natural waterways. The program includes mapping of the storm sewer system, screening stormwater outfalls to detect pollutant discharges, and tracking and elimination of illicit discharges. The City has adopted an ordinance prohibiting illicit discharges and illicit connections.
  • Construction Site Stormwater Management: The City of New Braunfels implements and enforces a program to reduce pollutants in stormwater runoff associated with construction activity. The program includes review of site plans to assess for adequate stormwater controls and routine inspections of active construction sites. The City has adopted an ordinance requiring erosion and sediment controls at active construction sites to minimize pollutant discharges.
  • Stormwater Management in Areas of New Development: The City of New Braunfels is addressing stormwater pollution in areas of new development by requiring the implementation of permanent stormwater management measures for new developments adding more than 5,000 square feet of impervious cover (as required by Section 13 of the City's Drainage and Erosion Control Design Manual). The City has established an ordinance requiring the inspection and maintenance of permanent stormwater BMPs to ensure adequate operation and functionality. The City also encourages the use of Low Impact Development (LID) concepts in areas of new development and redevelopment to mitigate the negative effects of stormwater runoff and pollution.
  • Pollution Prevention and Good Housekeeping for Municipal Operations: The City of New Braunfels is implementing an operation and maintenance program to prevent and reduce pollutant runoff from municipal operations. The City will adopt and implement stormwater management policies and procedures designed to protect water quality. This program will include stormwater management training for City staff, routine inspections of City-owned facilities to identify and address stormwater concerns, and installation of stormwater controls at City-owned facilities.
Annual Reports

The City is required to submit a report to the TCEQ at the end of each fiscal year. These reports describe the activities related to the MS4 program the City has accomplished within that year. Below are the reports for the past several years that the City has had the MS4 permit.

Stormwater Management and Bacteria Loading 

The City and local stakeholders has developed a Watershed Protection Plan (WPP) to address bacteria loading to both the Dry Comal Creek and the Comal River. 

Three Tips for Reducing Bacteria Loading:
  1. Avoid feeding wildlife including deer, ducks, and geese. Feeding wildlife can lead to concentrated populations of animals which may result in increased bacteria content in our local waterways. Concentrated populations of wildlife can also result in the proliferation of harmful diseases among the animals. Feeding of wildlife is unhealthy for the wildlife themselves as decreases their ability to locate food on their own. Please view the information from the Texas Parks and Wildlife Department regarding the negative impacts of feeding ducks.
  2. Pick-up after your pet. Pet waste can be a significant source of bacteria in our rivers and creeks.
  3. Perform routine maintenance of your septic system. It is recommended that your septic system be inspected regularly and pumped every 3-5 years. Additional information regarding septic system maintenance can be found by following this link (TCEQ: Basics for Septic Systems).
  4. More information about septic systems for New Braunfels residents can be found at the City's On-Site Sewerage Facilities website. For residents outside of the city limits but within the ETJ, please refer to the appropriate county for septic system information: Comal County Engineer's Office, Guadalupe County Environmental Health
