About Stormwater

The term stormwater refers to surface water that flows across the land into creeks, rivers and lakes. When it rains, stormwater runoff picks up pollutants such as litter, fertilizer, grass clippings or pet waste and carries them down the storm drain. Storm drains channel water directly into the waterway without any treatment or filtration. It will eventually find its way to area lakes, which are the primary water supply for most cities in Texas.

  • Clean debris from ditch
  • Creek bank stability or erosion investigation
  • Drainage investigation
  • Illicit discharge (disposing pollutants into the street and drainage system)
  • Obstruction in creek or floodplain
  • Sweep the street

Stormwater Regulations

The City Stormwater Discharge Ordinance was adopted to comply with the TCEQ MS4 Permit. This required the development of a Stormwater Management Program (SWMP) (PDF) to protect water quality to the maximum extent practicable. The Stormwater Utility Fee was established to provide funds necessary to meet the regulatory requirements.

The permit required the SWMP to include six minimum control measures. These are:

  • Public Education, Outreach and Involvement
  • Illicit Discharge Detection and Elimination
  • Construction Site Stormwater Runoff Control
  • Post Construction Stormwater Management
  • Pollution Prevention and Good Housekeeping for Municipal Operations
  • Industrial Stormwater Sources


Homeowner Associations (HOAs)

Many HOAs have maintenance responsibilities for common areas that include ponds, creeks and other stormwater features.   The Stormwater Division published Maintenance Guidelines (PDF) for HOAs and other land managers to understand the best management practices for these features.


How You Can Protect Stormwater

You should be aware of these common pollutants and how you can help:

  • Fertilizer - Should be applied at appropriate rates or consider organic fertilizers
  • Hazardous Household Chemicals - Should be disposed of properly
  • Herbicides and Pesticides - Use only when necessary and consider natural alternatives
  • Pet Waste - Must be removed in parks and should consider yard cleaning
  • Pool / Spa Water - Allow water to dechlorinate for 3 days before discharging
  • Sediment - Vegetate or mulch bare soil and protect dirt piles from washing away
  • Trash / Litter - Should not leave outside where it can be moved by wind or water
  • Vehicle Fluids - Should take precautions to not spill and dispose of properly
  • Yard Waste - Dispose of grass clippings and leaves appropriately or consider composting

Stormwater Fee Credits

Non-residential property managers have opportunities to improve stormwater quality. For this reason the Stormwater Fee Credit program (PDF) was developed to encourage implementation and maintenance of activities and structures that improve stormwater quality.

Commercial and Industrial Activities

You may be required to obtain Multi-Sector General Permit coverage from TCEQ. To ensure you are in compliance please check the TCEQ Small Business and Local Government Assistance website. Those who obtain coverage under that permit can electronically submit the required MS4 notifications to email MS4.

Construction Activity

Before beginning a construction project you should check the requirements of the Stormwater Ordinance and the 2018 General Permit to Discharge under the Texas Pollutant Discharge Elimination System. Those who obtain coverage under that permit can electronically submit the required MS4 notifications by emailing MS4. View the Guidelines for SWP3 and Erosion Control Plan Preparation (PDF) in Frisco.

How Community Organizations Can Help

If your organization needs a speaker or topic for an upcoming event, email the Stormwater Manager.
