(2) Contact information for the owner of the land, the developer, the ESC plan designer and person responsible for the implementation and maintenance of the plan; project name; project vicinity map.
(3) Permit Verification.
A. Jurisdictional Wetland: In areas where jurisdictional wetlands as defined by an on-site delineation verified by the United States Army Corps of Engineers will be affected, a copy of the wetland delineation report and a copy of the appropriate permit showing project approval and any restrictions that apply to site activities shall be submitted with the ESC Plan, or notification thereof.
B. An Ohio environmental Protection Agency (OEPA) National Pollutant Discharge Elimination System (NPDES) permit with permit verification number or Notice of Intent shall be submitted with the ESC Plan.
(4) Project Description: A brief description of the project and types of soil- disturbing activities. Note specifically items not self-evident from the plan drawings. The project description shall list total project acreage, north arrow, and adjacent property boundaries.
(5) Existing site conditions shown with maximum scale of 1”=200’ and 2’ contour intervals; locations and names of soil type boundaries, vegetation, ditches, springs, streams, lakes, wetlands, woods, agricultural fields; location of downstream lakes and wetlands within 1000’ of project based on Wetland Inventory Maps: existing drainage patterns including direction of flow and watershed acreage.
(6) Grading plan showing types of soils and boundaries; limits of disturbance; areas of excavation and fill; final contours: and proposed drainage pattern, drainage calculations, including storm sewer inlets and permanent storm water basins. Basin detail shall be drawn to scale and show volumes, size of contributing drainage area and method for calculating trapping efficiency. Basins and/or ponds must conform to the Ohio Dam Laws (Ohio R.C. 1521.06).
(7) Erosion and Sediment Control plan showing location, type, and construction detail for perimeter controls; sediment settling devices; limits of disturbance; buffers for streams, wetlands, ponds, and drainages; seeding mixtures and rates; type of mulching and fertilizer.

D. Maintenance inspection schedule and party responsible for inspection and repair of erosion and sediment control devices.
E. Pre-Winter Stabilization meeting if project is to be through the Winter.
F. Final grading and permanent soil stabilization within 30 days of finishing final grade.
G. Removal of temporary erosion and sediment control devices.
H. Final Stabilization meeting with provisions for long-term maintenance of storm water facilities including mechanisms for notification of future responsible parties and/or property owners.
