(A) No site development or building permit shall be issued until said developer submits a site development plan, together with other submissions required by this chapter, and certifies that any land clearing construction or development involving the movement of earth shall be in accordance with such plan and submissions.
(B) Each application for a site development permit shall be made by the owner of the property or his authorized agent to the building inspector on a form furnished for that purpose. When grading or plant cover removal is proposed as a part of the building permit, application may be combined, and one plot plan in the number of copies required by the building inspector may be submitted showing building plans and the site development plans. In such instances, a land surveyor or engineer shall certify as to the accuracy of the existing and proposed contour lines. Each application shall be accompanied by the following, unless the director of building and zoning finds any item unnecessary to ensure compliance with the provisions of this chapter:
1. Vicinity Sketch: With respect to site developments, a vicinity sketch, showing acreage of site, boundary line survey, zoning, type of proposed sewer and water facilities, location of existing utilities, buildings and drains on and within one hundred feet (100') of the site, together with a legend and scale. There shall be included on or with such a vicinity sketch:
(a) A soil map of the subject property showing the predominant soil types on the site. For the purpose of this chapter, the soil map shall be the soil survey of Kankakee County, Illinois, prepared by the soil conservation service of the USDA.
(b) Information on those areas abutting or adjacent to the site to show existing drainage patterns and the drainage course that may affect, or be affected by the development of the site.
(c) The name and address of the developer or owner.
(d) The name and address of any consulting firm retained by the applicant, together with the name of the applicant's principal contact at such firm.
(e) Limits of the 100-year floodplain(s) as adopted by the federal insurance administration for the flood insurance program.
(f) Areas to be sodded, seeded, mulched or paved.
(g) Acreage of area to be vegetatively stabilized, if any.
(h) Areas to be left undisturbed.
2. Existing Topography: With respect to site grading, existing topography of the site and a one hundred foot (100') adjacent peripheral strip, proposed contours and final grades, and street profiles; and indicating what measures will be employed to protect cut and fill slopes from surface runoff.
3. Storm Drainage: Storm drainage by means of a plan based upon a competent storm drainage study, including a drainage area map and computations, and indicating what conditions now prevail at proposed and natural outlets such as:
(a) Whether the drainage course is bare earth or vegetated.
(b) Whether the natural or proposed outlet is subject to long term or continuous flow.
(c) Whether the existing outlet is actively eroding.
(d) Whether there is evidence of high water table (permanent or seasonal), as indicated by the soil survey of Kankakee County, Illinois, as prepared by the soil conservation service. This information may be supplemented by site soil borings that show groundwater elevations.
(e) Whether the area is subject to seepage or spring flow.
(f) The elevation of normal water level in all proposed and natural outlets.
(g) A profile below outlet for a sufficient distance to indicate the natural gradient of the accepting natural outlet and/or stream channel.
(h) A cross section and profile and existing stream channels where applicable.
(i) A ditch design and computations for all seeded, sodded, or bare earth outlets, ditches and similar water conduction facilities.
4. Estimated Schedule And Phasing Of Development Of The Site:
Phase I Stripping and/or clearing
Phase II Rough grading and construction
Phase III Final grading and vegetative establishment
Phase IV Maintenance
All site development plans submitted to the director of building and zoning for approval shall show all the erosion and sediment control measures needed to provide protection throughout all the phases of the construction listed above. These plans shall also include any off site borrow and spoil areas, sewer lines, utility lines, and haul and access road, and further indicate:
(a) The start of clearing date.
(b) Duration of exposure of disturbed areas.
(c) Installation of temporary sediment control measures (vegetative and structural) by phase and date.
(d) Installation of storm drainage by phase and date.
(e) Paving on streets and parking areas, if any, by phase and date.
(f) Establishment of permanent vegetative cover (plans will show what will be done to shorten the duration of exposure of disturbed areas as soon after grading as possible), including seeding mixes and rates, type of sod, seedbed preparation, seeding dates, lime and fertilizer application, temporary seedings, if needed, mulching, or similar stabilization procedures.
(g) Details of all structural sediment control measures.
(h) Computations for sediment basins, if any.
5. Standards Incorporated: The standards and requirements of "Standards And Specifications For Soil Sediment Control In Northeastern Illinois", as adopted by the Kankakee County soil and water conservation district and the Illinois environmental protection agency's "Standards And Specifications For Soil Erosion And Sediment Control", adopted October 1987, are hereby incorporated into this chapter and made a part hereof by this reference, for purposes of exemplifying the considerations and factors which should enter into the preparation of a site development plan. All mandatory requirements of the above listed standards shall be met. (Ord. O-4-16-8, 5-2-2016)
