Storm Water Program

​Polluted storm water runoff from urbanized areas is a major cause of pollution. In Texas, The Texas Commission on Environmental Quality (TCEQ) is responsible for implementing Clean Water Act regulations. If you have any questions about the TCEQ Storm Water Program, please visit the TCEQ website. The regulations that affect Collin County are commonly called the Phase II Storm Water Program.

Collin County has prepared a Storm Water Management Program (SWMP) to comply with the requirements of the TCEQ's Texas Pollutant Discharge Elimination System (TPDES) General Permit TXR040000​. On June 8, 2009, Collin County received MS4 Permit Number TXR040035 ​​from the TCEQ. 

The objective of the SWMP is to implement a program to reduce the discharge of pollutants in stormwater. This program was developed with much coordination between the County and community to customize a program for Collin County that not only meets state and federal program requirements but also utilizes current activities, addresses issues that are important to the community, and is economically feasible.

The SWMP prepared by Collin County is a five-year program to reduce storm water pollution in the creeks and streams in the unincorporated, urbanized areas of the county.  

A schedule to implement the Storm Water Management Program, as well as measurable goals to track the implementation progress, has been developed in the DRAFT Collin County Storm Water Management Program 

The first permit term ran until Nov. 10, 2012, and the second permit term expired on Dec. 13, 2018. We are currently in our third permit term. This permit​ is good through 2023. Copies of the County's annual reports, for the current permit term, can be found below.

Past permit term programs and annual reports can be requested by contacting the Collin County Engineering department at (972) 548-3727.​
