Erosion & Sediment Control
Narrative Requirement

The Virginia Erosion and Sedimentation Control Handbook (VESCH) requires Erosion and Sediment Control Plan Narratives to address:

  • Project description - Briefly describes the nature and purpose of the land disturbing activity, and the area (acres) to be disturbed.
  • Existing site conditions - A description of the existing topography, vegetation and drainage.
  • Adjacent areas - A description of neighboring areas such as streams, lakes, residential areas, roads, etc., which might be affected by the land disturbance.
  • Off-site areas - Describe any off-site land-disturbing activities that will occur (including borrow sites, waste or surplus areas, etc.) Will any other areas be disturbed?
  • Soils - A brief description of the soils on the site giving such information as soil name, mapping unit, erodibility, permeability, depth, texture and soil structure.
  • Critical areas - A description of areas on the site which have potentially serious erosion problems (steep slopes, channels, underground springs, etc.)
  • Erosion and sediment control measures - A description of the methods to used to control erosion and sedimentation on the site. (Controls should satisfy minimum standards in Chapter 3, VESCH.)
  • Permanent stabilization - A brief description, including specifications, of how the site will be stabilized after construction is completed.
  • Stormwater runoff considerations - Will the development site cause an increase in peak runoff rates? Will the increase in runoff cause flooding or channel degradation downstream? Describe the strategy to control stormwater runoff.
  • Calculations - Detailed calculations for the design of temporary sediment basins, permanent stormwater detention basins, diversions, channels, etc. Include calculations for pre- and post-development runoff.
