(a) General.
(1) Erosion and sediment control practices used to satisfy the performance criteria shall meet the standards and specifications in the current edition of ODNR, Manual for Rainwater & Land Development, Ohio EPA, and Pike County Soil and Water Conservation District.
(2) The performance criteria are general guidelines and shall not limit the right of the Village to impose additional, more stringent requirements, nor shall the criteria limit the right of the Village to waive individual requirements.
(b) Design Criteria.
(1) Timing of Sediment Trapping Practices - Sediment control practices shall be functional throughout earth disturbing activity. Settling facilities, sediment barriers, and other practices intended to trap sediment shall be implemented as the first step of grading and within seven (7) days from the start of grubbing. They shall continue to function until the upslope development area is stabilized.
(2) Stabilization of Denuded Areas - Denuded areas shall have soil stabilization applied within seven (7) days if they are to remain dormant (undisturbed) for more than forty-five (45) days. Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is reached on any portion of the site, and shall also be applied within seven (7) days to denuded areas which may not be at final grade, but will remain dormant for longer than forty-five (45) days.
(3) Settling Facilities - Concentrated storm water runoff from denuded areas flowing at rates which exceed the design capacity of sediment barriers, shall pass through a sediment-settling facility. The facility’s storage capacity shall be sixty-seven (67) cubic yards per acre of drainage area.
(4) Sediment Barriers - Sheet flow runoff from denuded areas shall be intercepted by sediment barriers. Sediment barriers, such as sediment fences or diversions directing runoff to settling facilities, shall protect adjacent properties and water resources from sediment transported by sheet flow.
(5) Storm Sewer Inlet Protection - All storm sewer inlets which accept water runoff from the development area shall be protected so that sediment-laden water will not enter the storm sewer system without first being treated to remove sediment, unless the storm sewer system drains to a settling facility.
(6) Working in or Crossing Streams. Streams, including beds and banks, shall be stabilized immediately after in-channel work is completed, interrupted, or stopped. To the extent practicable, construction vehicles shall be kept out of streams. Where in-channel work is necessary, precautions shall be taken to stabilize the work area during construction to minimize erosion.
If a live (wet) stream must be crossed by construction vehicles regularly during construction, a temporary stream crossing shall be provided.
(7) Construction Access Routes. - Measures shall be taken to prevent soil transport onto surfaces where runoff is not checked by sediment controls, or onto public roads.
(8) Sloughing and Dumping. No soil, rock, debris, or any other material shall be dumped or placed into a water resource or into such proximity that it may readily slough, slip, or erode into a water resource unless such dumping or placing is authorized by the Village of Waverly, and, when applicable, the USACE or ODNR, for such purposes as, but not limited to, construction of bridges, culverts, and erosion control structures. Unstable soils prone to slipping or landslides shall not be graded, excavated, filled nor have loads imposed upon them unless the work is done in accordance with a qualified professional engineer’s recommendations to correct, eliminate, or adequately address such problems.
(9) Cut and Fill Slopes - Cut and fill slopes shall be designed and constructed in a manner which will minimize erosion. Consideration shall be given to the length and steepness of the slope, soil type, up-slope drainage area, groundwater conditions, and slope stabilization.
(10) Stabilization of Outfalls and Channels - Outfalls and constructed or modified channels shall be designed and constructed to withstand the expected velocity of flow from a postdevelopment, 10-year, 24 hour storm without eroding.
(11) Establishment of Permanent Vegetation - Permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until ground cover is achieved which, in the opinion of the Village provides adequate cover and is mature enough to control soil erosion satisfactorily and to survive adverse weather conditions.
(12) Disposition of Temporary Practices - All temporary erosion and sediment control practices shall be removed or permanently stabilized within thirty (30) days after final site stabilization is achieved or after the temporary practices are no longer needed, unless otherwise authorized by the Village.
(c) Maintenance. All temporary and permanent erosion and sediment control practices shall be designed and constructed to minimize maintenance requirements. They shall be maintained and repaired as needed to assure continued performance of their intended function. The person or entity responsible for the continued maintenance of permanent erosion controls shall be identified to the satisfaction of the Village.
