Stormwater Control Measure Design

Development and redevelopment within the Town’s municipal boundaries and its Extraterritorial Jurisdiction (ETJ) are required to manage stormwater in accordance with Section 5.4 of the Chapel Hill Land Use Management Ordinance (LUMO).

The LUMO requires development and redevelopment activities to manage and control stormwater runoff rate, volume, pollutants, and erosion/sedimentation in order to protect and safeguard the environment, property, and safety of residents within the Town’s jurisdiction. Low Impact Design (LID) measures are highly encouraged to meet the stormwater management performance criteria in the LUMO; the goal is to maintain a site’s predevelopment (or improve redevelopment) hydrologic conditions utilizing ecologically-based management techniques that infiltrate, filter, store and evapotranspirate stormwater on-site.

The Town of Chapel Hill Public Works Engineering Design Manual contains information about the design and acceptable techniques and controls to comply with the requirements of the LUMO. Acceptable stormwater management practices include those found in the most recent addition of the North Carolina Department of Environmental Quality Stormwater Best Management Practices Manual. The Town reserves the right to modify, amend, restrict, or otherwise change these accepted practices as may be necessary to achieve stated stormwater management goals.

 

Operation & Maintenance (O&M) Agreements

Each SCM in the Town of Chapel Hill is required to record an Operation and Maintenance (O&M) Agreement with the Register of Deeds with the final plat.  The original must be submitted to the Town.

 

Annual Inspection Reports

Section 5.4.8 (c) of the Chapel Hill Land Use Management Ordinance (LUMO) requires that “All stormwater management facilities must be inspected by the responsible party, in accordance with the approved schedule in the stormwater operation and maintenance plan, to identify maintenance and repair needs, and to ensure compliance with the requirement of the recorded operation and maintenance plan.” 

The property owner is responsible for the annual inspection of permitted stormwater control measures. The inspection must be performed by a qualified licensed Professional Engineer or other qualified professional with NCSU Stormwater BMP Inspection and Maintenance Certification.

 

Inspection Report Guidelines

Please follow the SCM Inspection Report Guidelines (PDF) for completing the inspection reports. If a site fails inspection, the report is still due to the Town by the inspection deadline. A 60-day period is then granted for repairs. Note that annual inspection reports submitted are subject to follow-up inspection by Town staff.
