All developments that have a larger common plan of development or sale equal to or larger than one (1) acre in size of disturbed area are subject to this chapter and shall follow all of the requirements set forth in this chapter.
(a) Description of the Plan of Construction: The following information shall be included in the Construction Site Conservation Plan:
(1) Site Description:
A. A description of the prior land uses of the site.
B. A description of the nature and type of construction activity (e.g., low density residential, shopping mall, highway, etc.).
C. A description of the total area of the site and the area of the site that is expected to be disturbed (i.e., grubbing, clearing, excavating, filling or grading, including off-site borrow, fill or spoil areas and off-site utility installation areas).
D. An estimate of the impervious area and percent imperviousness created by the construction activity.
E. The types of soils within, or affected by, the development area, and the location of all highly erodible or unstable soils as determined by the most current edition of the soil survey of the County, by the Natural Resources Conservation Service (NRCS),
F. The name and/or location of the immediate receiving stream or surface water(s) and the first subsequent named receiving water and the major river watersheds in which it is located.
(2) A vicinity sketch locating:
A. The larger common plan of development or sale
B. The development area
C. All pertinent surrounding natural features within 200 feet of the development site including, but not limited to:
1. Water resources such as wetlands, springs, lakes, ponds, rivers and streams (including intermittent streams with a defined bed and bank)
2. Conservation Easements
3. Other sensitive natural resources
4. The sensitive areas receiving runoff from the development
D. All off-site borrow or spoil areas
E. All off-site utility installation areas that are related to the planned project
(3) The existing and proposed topography shown in the appropriate contour intervals as approved (generally one-foot contours are used).
(4) The location and description of existing and proposed drainage patterns and facilities, including any allied drainage facilities beyond the development area and the larger common plan of development or sale.
(5) Existing and proposed watershed boundary lines, direction of flow and watershed acreage.
(6) The person or entity responsible for continued maintenance of all vegetative and/or mechanical BMPs for both the construction and post-construction phases of the development.
(7) Long-term maintenance requirements and schedules of all BMPs for both the construction and post-construction phases of the development.
(8) Long-term maintenance inspection schedules.
(9) The person or entity financially responsible for conducting the inspections of, and the maintenance of, permanent storm water conveyance and storage structures and all other conservation practices.
(10) The method of ensuring that funding will be available to conduct the long-term maintenance and inspections of all permanent storm water, soil erosion and sediment control and water quality practices.
(11) The location of any existing or planned riparian and/or wetland setback areas on the property.
(12) The plan must clearly describe, for each major construction activity, the appropriate BMPs and the general timing (or sequence) during the construction process of when the measures will be implemented; and, who (which contractor) will be responsible for implementation (e.g., Contractor A will clear, grub and install perimeter controls and Contractor B will maintain perimeter controls until final stabilization; Contractor C will conduct and document the scheduled inspections.)
(b) Construction Site Conservation Plan Elements: The Construction Site Conservation Plan shall include, at a minimum, the following information:
(1) The Construction Site Conservation Plan shall include a map showing the location of:
A. The limits of earth disturbing activity including excavations, filling, grading or clearing.
B. Drainage patterns during major phases of construction.
C. The location of each proposed soil erosion and sediment control BMP, including:
1. Permanent soil erosion control practices to be left in place after construction operations have been completed (e.g. level spreaders, permanent erosion control matting, gabions, rock lined channels, etc.),
2. Areas likely to require temporary stabilization during the course of site development,
3. Designated construction entrances where vehicles will access the construction site,
4. In-stream activities including stream crossings,
5. Areas designated for the storage or disposal of solid, sanitary and toxic wastes,
6. Dumpsters,
7. Cement truck washout,
8. Fuel tanks
9. BMPs that divert runoff away from disturbed areas and steep slopes where practicable including rock check dams, pipe slope drains, diversions to direct flow away from exposed soils, and protective grading practices,
10. Sediment settling ponds drawn to scale.
D. Existing and proposed locations of buildings, roads, parking facilities and utilities.
E. Boundaries of wetlands and stream channels the owner intends to fill or relocate for which the owner is seeking approval from the U.S. Army Corps of Engineers and/or Ohio EPA.
(2) The Construction Site Conservation Plan shall include a list of soil erosion and sediment control BMPs being used and the standards and specifications, including detailed drawings, for each BMP. This list shall include:
A. Methods of controlling the flow of runoff from disturbed areas so as to prevent or minimize erosion.
B. Identification of the Structural Practices to be used to control erosion and trap sediment from a site remaining disturbed for more than 14 days. A description shall be included of how each selected control will store runoff so as to let sediments settle out and/or divert flows away from exposed soils or act to limit runoff from exposed areas.
C. Identification for each Structural Practice of its size, detail drawings, maintenance requirements and design calculations.
D. The type and amount of plant seed, live plants, fertilizer, agricultural ground limestone and mulch to be used. Specification of soil testing requirements for fertility and lime requirements will be included. Specification for the use of perennial grass seed will also be included.
E. Settling ponds will be identified with basic dimensions and the calculations for size and volume.
F. Detailed drawings and installation requirements of all other structural control BMPs.
G. Any other soil erosion and sediment control related BMPs and items that are required by the Village of Sheffield.
H. For developments where the overall plan does not call for centralized sediment control capable of controlling multiple individual lots, a detail drawing of a project specific typical individual lot showing standard individual lot soil erosion and sediment control practices and the sequence and timing of BMP installation for the individual lots. This does not remove or eliminate the responsibility to designate and install specific soil erosion and sediment control practices for the storm water discharges.
(3) The Construction Site Conservation Plan shall include the scheduling, phasing, and coordination of construction operations and erosion and sediment control BMPs, including vegetative plantings and mulch.
(c) The Construction Site Conservation Plan shall include a description of the Storm Water Management (SWM) practices to be used on the site. The SWM element of the Plan shall include, at a minimum, the following:
(1) A map showing the location, drawn to scale, of permanent SWM conveyance, detention and retention structures, other SWM control structures and the SWM easements.
(2) A general description of the SWM strategy proposed to meet this chapter.
(3) Design calculations for all permanent SWM conveyance, detention and retention structures, and other SWM control structures.
(4) Any other SWM related items required by the Village of Sheffield.
