(A) Erosion control plans for areas less than one acre. The erosion control plan does not require signature and seal of a licensed design professional. The erosion control plan shall include the following items:
(1) Site location and boundary, including dimensions.
(2) Location of existing features, including but not limited to, waterways, drainage swales, roadside ditches, curb and gutter or edge of pavement and sanitary and storm sewer structures.
(3) Location of proposed structures.
(4) Spot elevations, existing and proposed, at a minimum, for the following: edge of pavement or curb and gutter, property corners, slope changes and finished floor elevation of structures.
(5) Location and dimensions of erosion control measures, including but not limited to, perimeter erosion control barrier, inlet protection, stabilized construction entrance and concrete washout/containment area.
(6) Name, address and phone number of the permittee.
(B) General criteria, standards and specifications. All erosion control measures required as part of any erosion control plan shall comply with the design criteria, standards and specifications identified in the most recent addition of the Natural Resources Conservation Service Illinois Urban Manual and most recent edition of Illinois Department of Transportation Standard Specifications of Road and Bridge Construction. The following standards and design elements are required and should be addressed in all erosion control plans:
(1) Erosion control sequence plan. All land disturbance activities including temporary erosion control best management practices, permanent vegetative cover and the various stages or phases of earth disturbance and construction shall follow a chronological sequence as shown on the erosion control plan.
(2) Phasing plan. A phasing plan of land development shall be required for all sites. The area and schedule for each phase shall be shown.
(3) Waste and material disposal. All waste and unused building materials (including garbage, cleaning wastes, wastewater, toxic materials, or hazardous materials) shall be disposed of following all federal, state, and local regulations.
(4) Stabilized construction entrance. Each site shall have a stabilized construction entrance installed to prevent sediment from being tracked onto public and private roadways.
(5) Culvert and inlet protection. All on site storm culverts and inlets, and the impacted off-site downstream culverts and inlets shall be protected with appropriate best management practices.
(6) Runoff control. Runoff from the entire disturbed area from the site shall be controlled by all appropriate best management practices. If a channel or area of concentrated runoff passes through or adjacent to the site, silt fences shall be placed along the channel edges. Attention shall be given to the land area and slopes to be controlled before choosing an appropriate best management practices.
(7) Sediment cleanup. All off-site sediment deposits occurring as a result of land disturbing activities shall be cleaned up by the applicant before the end of each work day. Flushing may not be used as a cleanup method.
(8) Disturbance timing. Removal of existing vegetation shall be at a minimum. Existing vegetation shall be maintained until removal is necessary based upon each phase of construction. Appropriate best management practices shall be constructed prior to any land disturbance. Permanent vegetation shall be established as soon as practical after each phase of work on the site.
(9) Soil and material storage pile(s). Soil and material storage pile(s) containing more than 10 cubic yards of material shall not be located in a 100-year floodplain and must be at least 25 feet from a roadway ditch or drainage channel. If the storage pile(s) remain(s) for 14 or more calendar days, the perimeter shall be stabilized utilizing appropriate best management practices. At no time should soil or material piles block sight lines at roadway intersections or sidewalks, or run out into street(s), ditch(es) or adjacent property(s).
(10) Channelized and sheet flow drainage. Channelized and sheet flow runoff from adjacent areas passing through the site shall be diverted around disturbed areas, if practical, and the channel shall be protected. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels. If diversion of channelized flow and/or sheet flow is impractical, the flow shall be controlled through appropriate best management practices to prevent erosion and carrying off of sediment and pollutants.
(11) Steep slope conditions. Sites with slopes of 12% or more shall require the use of additional best management practices, i.e., erosion blanket(s)/pipe drain(s).
(12) Site de-watering. Water pumped from the site shall flow to a temporary sediment basin or other appropriate control designed for the highest de-water pumping rate to prevent sediment from leaving the sight. Water shall not be discharged in a manner that causes erosion of the site or receiving channels, nor should silt-laden water be pumped off-site.
(13) Final stabilization. The methods of final stabilization shall be identified. If seeding is to be used, the type of seed, rates and amount of seed shall be provided.

(A) All erosion and sediment control measures necessary to meet the requirements of these sections shall be maintained by the applicant during the period of land disturbance and land development activities in accordance with the standards of the Illinois Urban Manual in a satisfactory manner to ensure adequate performance of the erosion and sediment control measures until an erosion control plan completion notice is issued.
(B) The permittee shall immediately repair any sedimentation or erosion damage to property and drainage ways adjacent to the site resulting from land development and land disturbance activities.
(C) The permittee shall maintain and protect all on-site and off-site storm water drainage systems, drainage ways, floodplain and drainage easements as identified on the erosion control plan.
(D) The property owner shall be responsible for maintaining all erosion and sediment control measures necessary to meet the requirements of these sections.

The Village Code Enforcement Officer, engineers and/or designees will make inspections based on the following schedule:
(A) The erosion control plan will be checked for accuracy during the initial stake out inspection of the lot. If the erosion control BMPs are inadequate and do not coincide with the erosion control plan, the inspection will be failed and the permittee will need to remedy any deficiencies and have the site re-inspected before any land disturbance activity begins.
(B) Before the rough-in inspections (electrical, plumbing, mechanical, framing) are called in to the Village Utility office, the site will be checked for erosion control compliance. If the inspector finds inadequate erosion control BMPs, the village will delay the notification of the inspectors for the rough-ins until the deficiencies have been remedied.
(C) Before the final inspections (electrical, plumbing, mechanical, framing) are called in to the Village Utility office, the site will be checked for erosion control compliance. If the inspector finds inadequate erosion control BMPs, the village will delay the notification of the inspectors for the final inspections until the deficiencies have been remedied.
(D) Periodic inspections will be made throughout the life of the erosion control plan, including every time after a one-half inch or greater rainfall. Precipitation amounts in the village will be verified from the National Oceanic and Atmospheric Administration website at www.weather.gov., "central Illinois Springfield Spaulding Dam 24 hour precipitation". At any time the erosion control BMPs are inadequate, the Code Enforcement Officer can issue a ''Stop Work Order" until such time that the deficiencies are remedied.
