§ 14-149. Local erosion and sediment control plan.  


Latest version.
  • (a)

    The City hereby adopts by reference the regulations, references, guidelines, standards and specifications promulgated by the State Water Control Board and the City's Chesapeake Bay Public Information Manual for those projects located within a Chesapeake Bay Preservation Area for the effective control of soil erosion and sediment deposition to prevent the unreasonable degradation of properties, stream channels, waters and other natural resources. Such regulations, references, guidelines, standards and specifications for erosion and sediment control and any amendments thereto also shall include, but not be limited to, the "Virginia Erosion and Sediment Control Regulations" (9VAC25-840-10 et seq.) and the Virginia Erosion and Sediment Control Handbook published by the Virginia Department of Conservation and Recreation, as amended.

    (b)

    In accordance with Code of Virginia, § 62.1-44.15:52, for any plan approved prior to July 1, 2014, stream restoration and relocation projects that incorporate natural channel design concepts are not manmade channels and shall be exempt from any flow rate capacity and velocity requirements for natural or manmade channels.

    (c)

    In accordance with Code of Virginia, § 62.1-44.15:52, for any plan approved prior to July 1, 2014, any land-disturbing activity that provides for stormwater management intended to address any flow rate capacity and velocity requirements for natural or manmade channels shall satisfy the flow rate capacity and velocity requirements for natural or manmade channels if the practices are designed to:

    (1)

    Detain the water quality volume and to release it over 48 hours;

    (2)

    Detain and release over a 24-hour period the expected rainfall resulting from the one year, 24-hour storm; and

    (3)

    Reduce the allowable peak flow rate resulting from the 1½, two, and ten-year, 24-hour storms to a level that is less than or equal to the peak flow rate from the site assuming it was in a good forested condition, achieved through multiplication of the forested peak flow rate by a reduction factor that is equal to the runoff volume from the site when it was in a good forested condition divided by the runoff volume from the site in its proposed condition, and shall be exempt from any flow rate capacity and velocity requirements for natural or manmade channels.

    For plans approved on and after July 1, 2014, the flow rate capacity and velocity requirements of this subsection shall be satisfied by compliance with water quantity requirements in the Stormwater Management Act (Code of Virginia, § 62.1-44.15:24 et seq.) and attendant regulations, unless such land-disturbing activities are in accordance with 9VAC25-870-48 of the Virginia Stormwater Management Program Permit Regulations.

    (d)

    Pursuant to Code of Virginia, § 62.1-44.15:52, for any plan approved prior to July 1, 2014, an erosion and sediment control plan shall not be approved until it is reviewed by a certified plan reviewer. Inspections of land-disturbing activities shall be conducted by a certified inspector. The City's Erosion Control Program shall contain a certified program administrator, a certified plan reviewer, and a certified inspector, who may be the same person.

    (e)

    The program and regulations provided for in this article shall be made available for public inspection at the Office of the Department of Public Utilities.
