The Stormwater Inspections Section is responsible for the enforcement of the Soil Erosion and Sediment Control, Flood prone Area, Watercourse Buffer and Reservoir Watershed Protection Programs.
The Stormwater Inspectors have several types of inspections to perform which are covered under two types of permits:
Two inspection teams cover two regions of the City. These two teams consist of seven inspectors to serve you.
- The East Region serves the area east from Six Forks Road to South Saunders Street.
- The West Region serves the area west from Six Forks Road to South Saunders Street.
Please see the Stormwater Control Inspector Regional Map with a list of inspector contacts.
Soil Erosion and Sediment Control
Land Disturbance Permit
Any land-disturbing activity over 12,000 square feet in size is required by code to have a land-disturbing permit prior to the activity beginning. Once a permit is issued, the Stormwater inspector conducts a pre-construction meeting with the grading contractor and/or the developer to meet the inspectors that will monitor the site and communicate project requirements.
Once, the erosion control devices, as shown on the approved erosion and sedimentation control plans, are installed, an inspection is required by the inspector to ensure the devices are installed correctly. If the installation is correct, the grading process can begin on site. Once the inspection has been approved, the Stormwater inspector will conduct routine inspections to ensure the erosion control devices are being maintained and are adequate to retain sediment on site. The inspections of the site will continue until all work is complete and the site is stabilized.
Single Family Erosion Control
There is not a requirement to obtain a land-disturbing permit when building a single family home with less than 12,000 square feet of land disturbance. However, installation of erosion control measures are required for all single family lots regardless of size of disturbance. At a minimum, required measures include:
- A construction entrance utilizing 2-3" stone which measures 30 ft deep x 10 ft wide.
- Silt fence installed on low ends of site and back of curb to ensure utilization of construction entrance.
The Stormwater inspector will typically conduct an inspection once the footers are poured to ensure that erosion control measures are installed and maintained.
Flood Prone Areas
A "Flood Permit" is required for any activity conducted in/or adjacent to a flood prone area. Once a permit is obtained, the Stormwater inspector checks the site for installation of benchmarks and, upon completion, ensures that work is conducted per the approved permit. The inspector also requires that all necessary certifications (FEMA) are completed for the activity.
Watershed Protection Areas
Development activities in water-supply watershed protection areas (Falls Lake, Swift Creek, and Richland Creek watersheds) are required to obtain a stormwater tracking permit. Upon completion of the project, the Stormwater inspector ensures that necessary surveys have been performed, stormwater devices are installed and/or impervious surface limits are not exceeded.
The City of Raleigh lies within the Neuse River Basin and is subject to riparian buffer requirements. These buffers typically extend 50-feet from the top of a stream bank on each side of the stream. The NC Division of Water Quality enforces the buffer rules. However, the City requires a "Buffer Permit" for development activities on all properties that may contain surface waters subject to the riparian buffer rules. When a "Buffer Permit" is issued, the Stormwater inspector ensures that all watercourse buffers on the property are properly flagged and that no prohibited activities occur in the buffer.
