A. Contents Of Plan: Grading plans, site plans, preliminary plat of subdivision, or the subdivision improvement plans for grading land areas one acre or more shall include the following additional information:
1. Erosion and sediment control plans submitted to the designated official shall include three (3) sets of maps and plans with specifications showing proposed excavation, grading or filling and will include the following:
a. Full name and address of property owner.
b. Designation of property address and a location map.
c. Portion of the property that is to be excavated, graded or filled with excavated material.
d. Location of any sewerage disposal system or underground utility line, any part of which is within fifty feet (50') of the proposed excavation, grading or filling area and the location of any pipeline operated at a maximum service pressure in excess of twenty (20) psig, any part of which is within one hundred feet (100') of the proposed excavation, grading or filling area.
e. Existing grade and topography of the premises and the proposed finished grade and final contour elevation at a contour interval of not more than two feet (2') on United States geological survey datum.
f. Location and present status of any previous permitted grading operations on the property.
g. Details of any temporary drainage system proposed to be installed and maintained by the applicant and a comprehensive drainage plan designed to safely handle surface water, streams or other natural drains following heavy rains during grading operations.
h. Details of proposed water impoundment structures, embankments, sediment or debris basins, grass or lined waterways and diversions with the details and locations of proposed stable outlets and the location of any downstream impoundments which could be affected by the proposed grading.
i. Details of soil preparation and revegetation of the finished grade and of other methods of soil erosion control.
j. Proposed truck and equipment accessways to the work site.
k. Delineation of the 100-year floodplain and floodway as illustrated on the adopted FEMA FIRM and FEMA floodway maps, including any CLOMRs and LOMRs. For regulatory purposes, the village may also consider preliminary FEMA FIRM and floodway maps or site specific hydrologic/hydraulic modeling during review of the submittal.
l. A statement from the property owner or his agent assuming full responsibility for the performance of the operation as stated in the application. This statement shall also contain assurance that all village property, utility infrastructure, and roads will be adequately protected.
2. The proposed phasing of development of the site, including clearing, rough grading and construction, and final grading and landscaping. Phasing should identify the expected date on which clearing will begin, the estimated duration of exposure of cleared areas and the sequence of clearing, installation of temporary sediment control measures, installation of storm drainage, paving streets and parking areas, and establishment of temporary and permanent vegetative cover. The designated official may waive specific requirements for the content of submissions upon finding that the information submitted is sufficient to show that the work will comply with the objectives and principles of these regulations.
B. Additional Requirements Of Plan: The sediment and erosion control plan must define the measures to be taken to meet erosion control principles and standards as defined in section 12-2-5 of this chapter. The plan must ensure that sediment is not transported from the site by a storm event of 10-years, 24-hour frequency rainfall as published by the Illinois state water survey bulletin to rainfall for this region less the allowable release rate.
C. Conservation District Comments: When a plan is submitted to the designated official, the plan shall also be submitted to the county soil and water conservation district for review and comment. Such comments may pertain but need not be limited to:
1. Erosion and sedimentation control.
2. Soil use limitations.
3. Environmental considerations.
4. Contact Madison County soil and water conservation district:
