(A) A soil grading and drainage plan shall be submitted showing all measures necessary to meet the objectives of this chapter throughout all phases of construction. The development of a soil grading and drainage plan shall follow the requirements of this chapter and the procedures in the latest edition of the Illinois Procedures and Standards for Urban Soil Erosion and Sedimentation Control which is hereby incorporated into this chapter by reference. Standards and specifications for BMPs shall follow the requirements of this chapter and the criteria in the latest edition of the Illinois Urban Manual which is hereby incorporated into this chapter by reference. The Zoning and Building Director, or his or her designee, 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 this chapter. Permanent soil erosion and sediment control features needed at the completion of any development site shall be included in the submittal.
(B) The submitted soil grading and drainage plan shall include:
(1) Mapping and descriptions. The existing and proposed erosion and sediment control features of the property and immediate vicinity, including:
(a) Items as required for the grading and drainage plan submittal;
(b) Location of the slope disturbance line;
(c) Location and description of the soil erosion and sediment control measures to be employed during construction;
(d) For any structures proposed to be located on the slope side of the slope disturbance line, the map shall include the limits of disturbance, including tree removal, soil erosion, and sediment control measures during construction, details of method(s) proposed for providing slope stability, permanent stormwater control measures, and permanent erosion and sediment control measures, all being certified by a registered professional engineer or a certified professional erosion control specialist;
(e) The predominant soil types on the site, their location, and their limitations for the proposed use as defined by the USDA Natural Resources Conservation Service (NRCS);
(f) Location and description, including standard details, of all sediment control measures and specifics of sediment basins and traps, including outlet details;
(g) Location and description (specification) of all soil stabilization and erosion control measures, including seeding mixtures and rates, types of sod, method of seedbed preparation (type and extent of tillage, weed control, planting equipment, and the like), expected seeding dates, type, method, and rate of lime and fertilizer application (soil fertility testing required), kind and quantity of mulching for both temporary and permanent vegetative control measures, and types of non-vegetative stabilization measures; and
(h) Location and description of all runoff control measures, including diversions, waterways, and outlets.
(2) Larger sites. Larger sites, at the discretion of the Zoning and Building Director, or his or her designee, and those requiring a stormwater pollution prevention plan (SWP3), may also require the following:
(a) Location and description of methods to prevent tracking of sediment off site including construction entrance details, as appropriate;
(b) Description of dust and traffic control measures;
(c) Provisions for maintenance of control measures, including type and frequency of maintenance, easements, and estimates of the cost of maintenance; and
(d) Identification (name, address, and telephone) of the person(s) or entity which will have legal responsibility for maintenance of soil erosion control structures and measures during development and after development is completed.
