During the construction of any development, the developer shall be responsible for the control of erosion, sediment and runoff from the site. The practices shall, at a minimum, meet the criteria set forth in the most recent version of the WV Division of Environmental Protection’s (DEP) Erosion and Sediment Control Manual. In addition, the following are required:
(a) Cut and fill slopes shall be no greater than 2:1, unless approved by the Town Engineer.
(b) Clearing, except that necessary to establish erosion and sediment control devices, shall not begin until all erosion and sediment control devices have been installed and stabilized.
(c) Phasing shall be required on all sites disturbing greater than 20 acres, unless approved by the Winfield Planning Commission.
(d) Erosion control requirements shall include soil stabilization within seven (7) days of clearing or inactivity in construction.
(e) Special techniques that meet the design criteria outlined in the WV DEP Erosion and Sediment Control Manual for steep slopes or in drainage ways shall be used to ensure stabilization.
(f) Soil stockpiles must be stabilized or covered at the end of each workday.
(g) The entire site must be stabilized, using a heavy mulch layer or another method that does not require germination to control erosion, at the close of the construction season.
(h) Techniques shall be employed to prevent the blowing of dust or sediment from the site.
(i) Techniques that divert upland runoff past disturbed slopes shall be employed.
(j) A temporary stream crossing shall be installed and approved by the WV DEP if a wet watercourse will be crossed regularly during construction.
(k) Stabilization of the watercourse channel before, during and after any in-channel work.
(l) Stabilization adequate to prevent erosion located at the outlet of all pipes and paved channels.
(m) A temporary access road provided at all sites.
(n) Silt fencing or some other approved barrier shall be placed around all disturbed areas.
(o) The developer is responsible for keeping dirt, mud and debris off of existing streets and adjacent properties. Dirt, mud and debris that are carried onto Town or private property shall be removed within 24 hours of the developer’s notification by Town’s building official or planning staff.
(p) No person or development shall be granted a building permit for land-disturbing activity that would require the disturbance of more than 1 acre without the approval of an Erosion and Sediment control plan from the WV DEP or Soil Conservation Service (SCS). However, no approval is required for any emergency activity that is immediately necessary for the protection of life, property or natural resources or existing nursery and agricultural operations conducted as a permitted main or accessory use.
(q) Upon completion of the improvements, the subdivider shall stabilize soils through re-vegetation of disturbed areas or by means as shall be required and/or approved by the town engineer.
