The main goal
of the Carrollton Storm Water Management Program is to protect 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 the midst of an urban setting.
Today, we know
that storm water pollution is one of the biggest threats to the health of our
creeks. The problem is magnified by widespread development, which puts a lot of
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 our storm
sewer system empties directly into our waterways without any treatment.
In Carrollton, the polluted storm water runoff eventually flows into the
Trinity River, impacting the source of our drinking water. |

Because the sources
of contaminants are so widespread - our cars, streets, parking lots, lawns,
golf courses, construction sites, etc. - the runoff is referred to as "nonpoint
source pollution." Many of our 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 our surface waters, The U.S. Environmental Protection
Agency has issued regulations for urban areas, such as
Carrollton. The Stormwater Phase II
regulations are designed to guide us in our efforts to reduce water pollution.
Under the rules, the city will be issued a permit and is required to develop a
program to minimize the amount of contaminants discharged from our storm sewer
system.
As a Phase II city, we must
implement
six
minimum measures to improve stormwater quality. The creation of a
stormwater management program for the city of Carrollton is a huge task. Your
participation and support are necessary in order to adequately protect our
water resources and the environment. It's important for us to realize that we -
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!" |
