The Carrollton Stormwater Management Program protects the quality of our surface waters - ponds, creeks and the Trinity River. Clean water is a life-giving natural resource and the centerpiece of any healthy environment. Our waterways support a wealth of wildlife and aquatic habitat, and provide us with a glimpse of nature in an urban setting.
Stormwater pollution is one of the biggest threats to the health of our surface waters. The problem is magnified by widespread development, which puts stress on the environment. By converting land from an undisturbed condition to a developed state we've covered the landscape with impervious surfaces - buildings, roads, rooftops and parking lots. Rainwater that used to soak into the ground now becomes urban runoff. As it flows over the land, the runoff collects pollutants on its way to the nearest storm drain or creek. Unlike sewage, which is collected and treated, anything that flows into the storm sewer system empties directly into waterways without any treatment. In Carrollton, the polluted stormwater runoff eventually flows into the Trinity River, impacting the source of our drinking water.
Because the sources of contaminants are so widespread - cars, streets, parking lots, lawns, golf courses, construction sites, etc. - the runoff is referred to as "nonpoint source pollution." Many daily activities contribute to NPS pollution and can take their toll on water quality.
Common pollutants include sediment, oil and grease, detergents, fertilizers, pesticides, toxic metals, and harmful bacteria. Oil and grease and detergents are washed off of roads and parking lots. Fertilizers, pesticides and herbicides are released from lawns and landscaped areas. Sediment and debris are carried off of construction sites. Pet wastes and sanitary sewer overflows are the main source of harmful bacteria or pathogens.
To reduce the impacts of stormwater pollution on surface waters, The U.S. Environmental Protection Agency has issued regulations for urban areas, such as Carrollton. The Storm Water Phase II regulations are designed to guide our efforts to reduce water pollution. Under the rules, the city has a permit and is required to develop a program to minimize the amount of contaminants discharged from the storm sewer system.
As a Phase II Level 4 city under the current permit, Carrollton must implement six minimum measures to improve storm water quality. The creation of a stormwater management program for the City of Carrollton is a huge task and civic participation and support are necessary in order to adequately protect our water resources and the environment. It's important to realize that we, the citizens - not industry - are responsible for most of today's water quality impacts. As stewards of this indispensable resource, we must make changes in our daily activities to preserve the ecological integrity of our waterways for generations to come. Remember, it's our water so let's "Take it personally!"
