The Stormwater Management Program helps protect surface water quality within the city limits by reducing the discharge of pollutants into McKinney’s streams, lakes and waterways in accordance with the Clean Water Act.
You may think water pollution comes from factories discharging sludge into a waterway, but according to the EPA, nonpoint source pollution - pollution that comes from a large number of sources - is the leading cause of water quality problems in the U.S. today.
Stormwater contributes to water quality issues as rain flows over hard surfaces, picking up pollutants and carrying them into our stormwater system. This water, and the pollutants it carries, then empties into our lakes and streams without being treated before it arrives.
Stormwater Management is part of the city's Development Services Engineering Division.
