Stormwater Best Management Practices (BMPs) are implemented as a way of limiting and treating pollutants and other damaging effects of stormwater runoff in order to meet legislative and North Carolina Administrative Code requirements. There are two major categories of BMPs: Non-structural and Structural. Non-structural BMPs are typically passive or programmatic and tend to focus on source control and pollution prevention; reducing pollution in runoff by reducing the opportunity for the stormwater runoff to be exposed to pollutants. Structural BMPs refer to physical structures designed to remove pollutants from stormwater runoff, reduce downstream erosion, provide flood control, and promote groundwater recharge. Structural BMPs typically require engineering design and engineered construction.

Structural BMP O&M Agreements:Each structural BMP in Apex is required to submit an Operation and Maintenance (O&M) Agreement to the Town prior to final approval.

Structural BMP Inspection Reports: All BMP owners are responsible for having all BMPs on their property inspected annually by a qualified registered North Carolina professional engineer, land surveyor, or landscape architect performing services only in their area of competence. Each BMP owner will receive a 30-day notice from the Town the month before annual inspection is due. Please contact Public Works at 249-3427 for more information.
