Stormwater Control Measure Maintenance and Inspection Program

RD SCM inspection

Since the 1980s, the Town’s Land Use Ordinance (LUO) has required stormwater management as part of development projects. Beginning in 2004, the Town’s stormwater management efforts have been regulated under an NPDES (National Pollution Discharge Elimination System) permit.  One section of the permit is for “post-construction” stormwater management, which includes requirements for maintenance and inspection of “Stormwater Control Measures” (SCMs). SCMs are regulated stormwater devices that treat runoff to reduce both water quantity and quality impacts. The Town of Carrboro requires the property owner to take responsibility for maintenance and inspection of stormwater devices. 


Read the SCM Maintenance and Inspection Program Guide for program details and policies.

Property owners are required to do the following regarding SCMs:

  • Conduct maintenance regularly to ensure the function of the device, in accordance with minimum requirements set by the NC Department of Environmental Quality (NCDEQ)
  • Maintain records of maintenance performed
  • Have each SCM inspected at least annually by a qualified North Carolina professional
  • Submit an annual report including the results of the inspection and maintenance records from the previous year
  • Set aside funds sufficient to pay major, non-routine costs associated with keeping the SCM in proper condition
  • Submit a report annually stating that such funds have been set aside

Qualified Professionals

Carrboro requires that SCMs be inspected annually by a qualified North Carolina professional. Appropriate inspectors include Professional Engineers, Professional Landscape Architects, or others specially qualified by an appropriate training, testing and certification program.
