(a) Erosion and Sediment Control Plan.
(1) An erosion and sediment control plan shall be prepared and submitted to the Village Engineer.
(2) The erosion and sediment control plan shall be designed to meet the performance standards in Section 15-2-6 and other requirements of this Chapter.
(3) 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, the following items:
a. The name(s) and address(es) 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 the estimated start and end dates for construction.
b. Description of the site and the nature of the construction activity.
c. A sequence of construction of the development 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 duation of exposure of cleared areas, areas of clearing, installation of temporary erosion and sediment control measures, and establishment of permanent vegetation.
d. Estimates of the total area of the site and the total area of the site that is expected to be disturbed by construction activities.
e. Estimates, including calculations, if any, of the runoff coefficient of the site before and after construction activities are completed.
f. Calculations to show the expected percent reduction in the average annual sediment load carried in runoff as compared to no sediment or erosion controls.
g. Existing data describing the surface soil as well as subsoils.
h. Depth to groundwater, as indicated by Natural Resources Conservation Service.
i. Service soil information where available.
(4) The erosion and sediment control plan shall include a site map. The site map shall include the following items and shall be at a scale not greater than one hundred (100) feet per inch and at a contour interval not to exceed two (2) feet.
a. Existing topography, vegetative cover, natural and engineered drainage systems, roads and surface water. .Lakes, streams, wetlands, channels, ditches and other water courses on and immediately adjacent to the site shall be shown. Any identified one hundred (100) year flood plains, flood fringes and floodways shall also be shown.
b. Boundaries of the construction site.
c. Drainage patterns and approximate slopes anticipated after major grading activities.
d. Areas of soil disturbance.
e. Location of major structural and non-structural controls identified in the plan.
f. Location of areas where stabilization practices will be employed.
g. Areas which will be vegetated following construction.
h. Area of wetland acreage on the site and locations where stormwater is discharged to a surface water or wetland.
i. An alphanumeric or equivalent grid overlying the entire construction site map.
(5) Each erosion and sediment control plan shall include a description of appropriate controls and measures that will be performed at the site to prevent pollutants from leaving the site. The plan shall clearly describe the appropriate control measures for each major activity and the timing during the construction process that the measures will be implemented. The description of erosion controls shall include, when appropriate, the following minimum requirements:
a. Description of interim and permanent stabilization practices, including a practice implementation schedule. Site plans shall ensure that existing vegetation is preserved where attainable and that disturbed portions of the site are stabilized.
b. 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 Village Engineer, structural measures shall be installed on upland soils.
c. Management of overland flow at all sites, unless otherwise controlled by outfall controls.
d. Trapping of sediment in channelized flow.
e. Staging construction to limit bare areas subject to erosion.
f. Protection of downslope drainage inlets where they occur.
g. Minimization of tracking at all sites.
h. Cleanup of off-site sediment deposits.
i. Property disposal of building and waste materials at all sites.
j. Stabilization of drainageways.
k. Control of soil erosion from dirt stockpiles.
I. Installation of permanent stablization practices as soon as possible after final grading.
m. Minimization of dust to the maximum extent practicable.
(6) The erosion and sediment control plan shall require controls be placed to slow the flow of water at discharge locations and along the length of any outfall channel, as necessary, to provide a non-erosive flow from the structure to a water course so that the natural physical and biological characteristics and functions are maintained and protected.
(b) Erosion and Sediment Control Plan Statement. For each construction site identified under Section 15-2-4(a), an erosion and sediment control plan statement shall be prepared. This statement shall be submitted to the Village Engineer. The control plan statement shall briefly describe the site, including a site map. Further, it shall also include the best management practices that will be used to meet the requirements of the Chapter, including the site development schedule.
(c) Amendments. The applicant shall amend the plan if any of the following occur:
(1) There is a change in design, construction, operation or maintenance at the site which has the reasonable potential for the discharge of pollutants to waters of the state and which has not otherwise been addressed in the plan.
(2) The actions required by the plan fail to reduce the impacts of pollutants carried by the construction site runoff.
(3) The Village Engineer notifies the applicant of changes needed in the plan.
