Small Actions, Big Impact: Managing Stormwater Together
Every resident plays a role in reducing pollution and flooding across our community. When rainwater flows over rooftops, driveways, lawns, and streets instead of soaking into the ground, it picks up dirt, fertilizers, oil, and pet waste that drain into ditches, streams, and rivers. This process creates what’s known as nonpoint source pollution runoff that carries pollutants from many everyday activities rather than a single source.
Common pollutants like nitrogen and phosphorus from lawn fertilizers can reduce oxygen in water, harm fish, and degrade water quality. As development adds more hard surfaces, runoff increases, raising the risk of flooding and contamination. To address these issues, the Pitt County Stormwater Ordinance promotes the use of Stormwater Control Measures (SCMs) methods that slow, filter, and store stormwater to protect water quality and reduce flooding.
Clean, healthy waterways support wildlife, recreation, property values, and our overall quality of life. By using SCMs and maintaining good habits at home, residents help keep Pitt County’s rivers and streams clear for generations to come.
Reducing Flooding and Protecting Water Quality
Small, consistent actions can make a lasting difference in protecting local streams, rivers, and neighborhood quality of life.
Every household can help reduce stormwater pollution with small, everyday actions:
- Store and dispose of paints, cleaners, and chemicals properly.
- Use fertilizers and pesticides sparingly and never before rain.
- Compost or bag yard waste instead of blowing it into drains.
- Wash cars on grass or gravel to limit runoff.
- Recycle used motor oil and auto fluids at approved collection sites.
Maintaining Neighborhood BMPs
Homeowners Associations (HOAs) are responsible for maintaining Best Management Practices (BMPs) within their communities. Each HOA should create a written plan outlining inspection schedules, record keeping, and funding for regular maintenance.
Plan Essentials:
- Keep site plans, easements, and inspection reports organized.
- Budget for both routine upkeep and major repairs.
- Hire professionals for sediment removal or structural work.
- Educate residents about SCM maintenance and pollution prevention.
Managing Runoff with Natural and Engineered SCMs
Stormwater Control Measures (SCMs) help manage stormwater by slowing, filtering, and absorbing runoff before it reaches local waterways. Some use natural landscapes like grass and plants, while others are engineered systems designed to handle larger volumes of water. Both approaches reduce flooding, limit pollution, and improve community appearance.
Vegetated Swales
Shallow, grass-lined channels that slow and filter runoff. Affordable and low-impact, they work best when combined with other stormwater controls.
Maintenance: Inspect seasonally, remove debris, and mow to about 3–4 inches. Replace vegetation if bare spots appear or erosion occurs.
Riparian Buffers
Vegetated areas along streams or ponds that trap sediment, filter pollutants, and prevent erosion. Keep the first 30 feet near water natural; limited landscaping may occur beyond that.
Maintenance: Clear debris as needed and schedule quarterly inspections by a certified BMP inspector.
Stormwater Wetlands
Shallow ponds with native plants that remove pollutants like nitrogen and phosphorus, help prevent flooding, and enhance neighborhood beauty.

Maintenance: Inspect monthly and after rain. Remove trash, control erosion, and clear inlets and outlets. Avoid fertilizers and pesticides.
Dry Detention Ponds
Basins that temporarily collect runoff, allowing sediment and pollutants to settle before water is released. They typically dry between storms.
Maintenance: Inspect quarterly, remove debris and sediment, and repair erosion or bare areas as needed.
Wet Detention Ponds
Ponds that hold a permanent pool of water to trap pollutants and support aquatic plants, reducing flooding and improving water quality.
Maintenance: Inspect monthly and after major storms. Keep inlets and outlets clear, remove sediment every 5–7 years, and mow side slopes. Avoid small outlet pipes that can clog easily.
