Stormwater and the Environment

Stormwater runoff is the leading cause of water pollution in North Carolina

As land is developed, impervious surfaces created increase runoff from rainfall or snowmelt events. Impervious surfaces such as rooftops, driveways, sidewalks and streets prevent stormwater runoff from naturally soaking into the ground. Stormwater can pick up debris, chemicals, dirt and other pollutants and flow directly to a stream, river, lake, wetland, or into a storm sewer system. Anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing and providing drinking water.
 
While awareness and interest in environmental protection exists at the local government and citizen level, the County’s water resources continue to experience degradation. The length and number of streams on the State’s 303(d) list of impaired waters has increased since the list was first published in 1998. Also, a 2003 assessment of the County’s 82 watersheds as part of the С»ÆÑ¼ÊÓÆµ County Watershed Management Plan rated nearly 63% of the watersheds as impacted or degraded. In recent years, an average of 27 acres of land in С»ÆÑ¼ÊÓÆµ County is converted from a natural to a developing stage every day. If not managed properly, development in С»ÆÑ¼ÊÓÆµ County could result in the further impairment of these water resources, having a pronounced impact on the quality of life in С»ÆÑ¼ÊÓÆµ County.
 
Increased stormwater runoff can erode stream channels, increase pollutant loading in surface waters, cause downstream flooding and prevent groundwater recharge. Protecting our water resources is vital for a variety of reasons, including ensuring an adequate supply of safe drinking water, protection of fish and wildlife habitat, human health and recreation.

Clean Water Begins at Home

Everyday actions around your home and yard can have a big impact on local water quality. By being mindful of how we manage waste, chemicals, and runoff, community members can help prevent pollution from reaching our creeks and rivers. One of the most important things that a community member can do is to never dump anything down storm drains or in streams.  

The table below highlights common pollutants and simple steps you can take to keep our water clean.

Pollutant What community members can do
Sediment
  • Vegetate bare spots in your yard
  • Contact your local erosion control program to report mud in streets or offsite sediment from new development projects
Excess nutrients
  • Minimize fertilizer use and do not apply prior to rains
Pet waste
  • Pick up after your pet and properly dispose of waste
Yard clipping
  • Sweep up driveways, sidewalks, and gutters
  • Bag your waste for pickup or compost
Pesticides
  • Minimize application of pesticides and do not apply prior to rains
  • Use least toxic pesticides, when possible, and follow labels
  • Learn how to prevent pest problems using permaculture solutions
Auto fluids
  • Check your car for leaks and recycle your motor oil
  • Use a professional car maintenance facility or collect your waste oil and recycle
Car washing
  • Use a professional car wash or wash your car so that drainage goes to your lawn not a storm drain or ditch
Litter
  • Pick up litter and properly dispose
