 Erosion and Sediment Control
           Program
    Presentation to the Board of Supervisors
                 June 20, 2007
  Purpose of the E&S Program
• Program required by Code of Virginia
  Title 10.1, Chapter 5, Article 4
• Protect downstream properties
• Maintain or improve water quality
• Control erosion & sediment
• Maintain stream channel integrity
• Minimize flooding
             Watersheds are in Dynamic
                    Equilibrium
                                              Lane’s Relationship
                                                 Qs D50 ∞ Qw S

                                              Qs = Quantity of Sediment
                                              D50 = Sediment Particle Size
                                              Qw = Quantity of Water
                                              S = Slope of Channel

    Maintaining Watershed Health
• General stormwater runoff from impervious
  surface areas is the major source of microbial
  pathogen pollution.
• Studies in North Carolina show watersheds with
  impervious surface cover between 10% and
  20% are impaired
• Watersheds with impervious surface cover over
  20% are severely polluted with all areas unsafe
  for shellfishing.

    the microbial pollution of coastal waters. Hydrobiologia 460: 185-193, 2001.
