RESIDENTIAL SINGLE LOT EROSION CONTROL REQUIREMENTS

Erosion and Sedimentation Control (SEC) permits are required for most individual lots INCLUDING THOSE less than 1 acre.

Plan and Permit Requirements – all lots that are part of a larger common plan of development or sale (see definition below) must submit an erosion and sedimentation control plan and obtain a land disturbance permit.

Common Plan of Development or Sale:  
 A contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under one common plan. The "common plan" of development or sale is broadly defined as any announcement or piece of documentation (including a sign, public notice or hearing, sales pitch, advertisement, drawing, permit application, zoning request, computer design, etc.) or physical demarcation (including boundary signs, lot stakes, surveyor markings, etc.) indicating construction activities may occur on a specific plot.

PART A - Subdivision Lots
  • Homebuilders developing lots within a subdivision (a larger common plan of development or sale*) shall submit a plot plan showing the area and acreage to be disturbance on each lot, and may submit a copy of the Standard Erosion Plan for Lots or a custom erosion control plan for the lots to be disturbed and obtain a land disturbance permit. Note: Sediment and erosion control measures are performance-based. You must use measures that are adequate to retain sediment onsite. A streamlined process is under development.
  • Residential Tract developers shall apply for a land disturbance permit with an erosion and sedimentation control plan for the subdivision including all disturbed lots. The plan shall include standard erosion measures for all lot drainage patterns. 
PART B - Individual Lots (outside of a subdivision)
  • Individual lots that are not part of a subdivision (a larger common plan of development or sale*) with over 1 acre of disturbance shall apply for a land disturbance permit with an erosion and sedimentation control plan.

Minimum E&SC measures are required for all lots regardless of size of disturbance.
  1. Construction entrance for each point of access measuring 10 feet in width by 30 feet in length of surge stone, railroad ballast or equivalent to minimize tracking sediment off site
  2. Silt fence at the street front and at low sides of lot prior to initial footing inspection conducted by Wake County building Inspectors.

  Tips for Success:
  • Watch, Listen and Plan for RAIN.
  • Talk to your subcontractors and workers – parking on shoulder and entering lot from any point other than the construction entrance shall be prohibited!
  • Establish vegetation ASAP – temporary seeding, mulching or straw and tack can save on offsite remediation.
  • Inspect your site and measures at the end of every workday and after each heavy rain event.
  • Maintain devices and measures – clean or replace when measures are 50% full.
  • Washing the streets is not a good method of remediation – a square-point shovel and push broom are more appropriate and less expensive.
  • Make repairs immediately.
