When rainwater lands on rooftops, streets, driveways and other impervious surfaces, the runoff flows into catch basins, pipes, or other conveyances (such as swales and ditches) around your neighborhood. A Stormwater Control Measure (SCM) is a device that helps reduce the quantity and improve the quality of stormwater runoff. A SCM may be located in your backyard, neighborhood, or at local business. In the City of High Point there are various types of SCMs.
Regular maintenance is crucial to ensure that a water quality device effectively removes stormwater pollutants. Pursuant to Section 9-7-5 (d) 5 of the City of High Point Development Ordinance, engineered stormwater control structures must be inspected annually and the City is required to record the results and notify the responsible property owner or owner's association when maintenance or repairs are necessary. Upon inspection, if repairs are needed, the responsible party is given 90 days to make the necessary improvements. The City of High Point BMP Design Manual (PDF) provides general design guidelines for major SCMs and recommended maintenance schedules.
