(b) The erosion and sediment control plan shall be designed to meet the performance standards in S. 07*, S. 08*, and other requirements of this ordinance.
(c) The erosion and sediment control plan shall address pollution caused by soil erosion and sedimentation during construction and up to final stabilization of the site. The erosion and sediment control plan shall include, at a minimum, all of the following items:
1. Names and addresses of the owner or developer of the site, and of any consulting firm retained by the applicant, together with the name of the applicant’s principal contact at such firm. The application shall also include start and end dates for construction.
2. Description of the construction site and the nature of the land disturbing construction activity, including representation of the limits of land disturbance on a United States Geological Survey 7.5 minute series topographic map.
3. Description of the intended sequence of major land disturbing construction activities for major portions of the construction site, including stripping and clearing; rough grading; construction of utilities, infrastructure, and buildings; and final grading and landscaping. Sequencing shall identify the expected date on which clearing will begin, the estimated duration of exposure of cleared areas, areas of clearing, installation of temporary erosion and sediment control measures, and establishment of permanent vegetation.
4. Estimates of the total area of the construction site and the total area of the construction site that is expected to be disturbed by land disturbing construction activities.
5. Calculations to show the compliance with the performance standard in S. 08 (3)(b)1.
6. Existing data describing the surface soil as well as subsoils.
7. Depth to groundwater, as indicated by Natural Resources Conservation Service soil information when available.
8. Name of the immediate named receiving water from the United States Geological Survey 7.5 minute series topographic maps.
(d) The erosion and sediment control plan shall include a site map. The site map shall include all of the following items and shall be at a scale not greater than 100 feet per inch and at a contour interval not to exceed five feet:
1. Existing topography, vegetative cover, natural and engineered drainage systems, roads, and surface waters. Lakes, streams, wetlands, channels, ditches, and other watercourses on and immediately adjacent to the site shall be shown. Any identified 100-year flood plains, flood fringes, and floodways shall also be shown.
2. Boundaries of the construction site.
3. Drainage patterns and approximate slopes anticipated after major grading activities.
4. Areas of soil disturbance.
5. Location of major structural and non-structural controls identified in the erosion and sediment control plan.
6. Location of areas where stabilization BMPs will be employed.
7. Areas that will be vegetated following land disturbing construction activities.
8. Areas and locations of wetland on the construction site, and locations where storm water is discharged to a surface water or wetland within one-quarter mile downstream of the construction site.
9. Areas used for infiltration of post-construction storm water runoff.
10. An alphanumeric or equivalent grid overlying the entire construction site map.
(e) Each erosion and sediment control plan shall include a description of appropriate control BMPs that will be installed and maintained at the construction site to prevent pollutants from reaching waters of the state. The erosion and sediment control plan shall clearly describe the appropriate erosion and sediment control BMPs for each major land disturbing construction activity and the timing during the period of land disturbing construction activity that the erosion and sediment control BMPs will be implemented. The description of erosion and sediment control BMPs shall include, when appropriate, all of the following minimum requirements:
1. Description of interim and permanent stabilization practices, including a BMP implementation schedule. The erosion and sediment control plan shall ensure that existing vegetation is preserved when attainable and that disturbed portions of the site are stabilized.
2. Description of structural practices to divert flow away from exposed soils, store flows, or otherwise limit runoff and the discharge of pollutants from the site. Unless otherwise specifically approved in writing by the [administering authority], structural measures shall be installed on upland soils.
3. Management of overland flow at all areas of the construction site, unless otherwise controlled by outfall controls.
4. Trapping of sediment in channelized flow.
5. Staging land disturbing construction activities to limit exposed soil areas subject to erosion.
6. Protection of downslope drainage inlets where they occur.
7. Minimization of tracking at all vehicle and equipment entry and exit locations of the construction site.
