Pursuant to section VA Code § 62.1-44.15:54, the VESCP authority hereby establishes a VESCP program and adopts the regulations promulgated by the Board (for the effective control of soil erosion and sediment deposition to prevent the unreasonable degradation of properties, stream channels, waters and other natural resources) and the Virginia Erosion & Sediment Control Handbook, third edition. Stream restoration and relocation projects that incorporate natural channel design concepts are not man-made channels and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made channels as defined in any regulations promulgated pursuant to this section or VA Code § 62.1-44.15:54 or § 62.1-44.15:65. In accordance with VA Code § 62.1-44.15:52, any plan approved prior to July 1, 2014 that provides for stormwater management that addresses any flow rate capacity and velocity requirements for natural or man-made channels shall satisfy the flow rate capacity and velocity requirements for natural or man-made channels if the practices are designed to (i) detain the water quality volume and to release it over 48 hours; (ii) detain and release over a 24-hour period the expected rainfall resulting from the one year, 24-hour storm; and (iii) reduce the allowable peak flow rate resulting from the 1.5, 2, and 10-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 man-made channels
(A) For plans approved on and after July 1, 2014, the flow rate capacity and velocity requirements for natural and man-made channels shall be satisfied by compliance with water quantity requirements specified in VA Code § 62.1-44.15:28 of the Stormwater Management Act and 9VAC25-870-66 of the Virginia Stormwater Management Program (VSMP) regulations, unless such land-disturbing activities are in accordance with the grandfathering provisions of the Virginia Stormwater Management Program (VSMP) Regulations.
(B) Pursuant to VA Code § 62.1-44.15:53, an erosion 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 Erosion Control Program of Northampton County shall contain a certified program administrator, a certified plan reviewer, and a certified inspector (who may be the same person.)
(C) Northampton County hereby designates Northampton County Department of Planning, Permitting and Enforcement as the plan-approving authority.
(D) The program and regulations provided for in this chapter shall be made available for public inspection at the office of the Northampton County Department of Planning, Permitting and Enforcement.
