The Town of Knightdale administers its own erosion and sedimentation control program that aims to prevent sediment from leaving active construction projects and polluting our local waterways.
We accomplish this by enforcing all state and local erosion control regulations and by working with developers, builders, and landowners within the Town's corporate limits.
IMPORTANT UPDATE: The Town of Knightdale has recently clarified enforcement under Chapter 9.4 of the Unified Development Ordinance (Illicit Discharges) to address materials generated on construction sites that enter the stormwater system.
Under UDO Chapter 9.4, the discharge or placement of materials that may be transported by stormwater into the Town’s storm drainage system, ditches, or local waterways is prohibited.
This includes construction-related waste, such as:
- Trash and packaging materials
- Construction debris
- Concrete washout or slurry
- Building materials and scrap
- Sediment-laden waste and loose materials
If these materials are allowed to enter or be transported by stormwater runoff into the Town’s storm drainage system or adjacent properties, they may be classified as an Illicit Discharge and are subject to enforcement under Chapter 9.4 of the Knightdale UDO.
To remain in compliance, contractors and site operators are responsible for implementing and maintaining proper waste management practices throughout the duration of construction.
At a minimum, construction sites must:
- Provide adequate waste receptacles (dumpsters, trash containers, material bins, etc.) onsite.
- Ensure receptacles are properly located and secured to prevent materials from being blown or washed offsite.
- Maintain receptacles throughout construction, including routine servicing and disposal.
- Remove loose construction debris regularly to prevent transport by wind or stormwater.
- Prevent materials from entering storm drains, ditches, or waterways through proper housekeeping and site management.
- Properly contain and dispose of concrete washout and other liquid wastes in designated facilities.”
Residential Lot Erosion Control
All builders and developers disturbing land in a subdivision (common plan of development) are required to have a land disturbance permit, even if the disturbance is less than 1 acre.
Builders outside a subdivision shall obtain a permit if disturbance is greater than 1 acre.
More information regarding individual lot ESC submittals can be found here.
Sediment and Erosion Control Standard Details
The Town of Knightdale utilizes Wake County and the NC Department of Environmental Quality standard drawings that illustrate the minimum acceptable standards for land development, disturbing or erosion control activities authorized under development regulations of the Town of Knightdale; however, these standards shall not supersede more restrictive prudent design requirements or good engineering practices as applied to specific situation on a case-by-case basis.

Town of Knightdale Unified Development Ordinance
Our local erosion control regulations can be found in Chapter 96 of the Code of Ordinances.
The Town of Knightdale is delegated by the State of NC to operate a local erosion control program. The overall goal of the Sedimentation Pollution Control Act (SPCA) and the NC Administrative Code (Code) Title 15 Chapter 4, is to prevent visible sedimentation into lakes, streams, natural watercourses, and onto adjoining properties. The SPCA outlines the regulatory requirements and gives authority to the Sedimentation Control Commission (SCC) and the Land Quality Section (LQS). The Code provides the administrative overview of how the SCC and LQS enforce the SPCA.
