(A) Grading, erosion control practices, sediment control practices and waterway crossings shall meet the design criteria set forth in the most recent version of the Illinois Urban Manual: A Technical Manual Designed for Urban Ecosystem Protection and Enhancement and shall be adequate to prevent transportation of sediment from the site to the satisfaction of the village. Cut and fill slopes shall be no greater than two to one (horizontal to vertical), except as approved by the village to meet other community or environmental objectives.
(B) Stripping and grading of natural resources, such as forests and wetlands, shall not be permitted, except when in compliance with all other federal, state and local laws, regulations and ordinances. Stripping techniques that retain natural vegetation and drainage patterns, as described in the Illinois Urban Manual - A Technical Manual Designed for Urban Ecosystem Protection and Enhancement shall be used to the satisfaction of the village.
(C) Stripping, except that necessary to establish sediment control devices, shall not begin until all sediment control devices have been installed and have been stabilized.
(D) Phasing shall be required on all sites disturbing greater than 30 acres, with the size of each phase to be established at plan review and as approved by the village.
(E) Erosion control requirements shall include the following.
(1) Erosion and sediment control barriers shall be installed within two calendar days of stripping activity.
(2) Soil stabilization shall be completed within five calendar days of stripping or inactivity in construction.
(3) If seeding or another vegetative erosion control method is used, it shall become established within 14 calendar days or the village may require the site to be reseeded or a non-vegetative option employed.
(4) Special techniques that meet the design criteria outlined in the Illinois Urban Manual: A Technical Manual Designed for Urban Ecosystem Protection and Enhancement on steep slopes or in drainage ways shall be used to ensure stabilization.
(5) Soil stockpiles must be stabilized or covered at the end of each workday.
(6) The entire site must be stabilized, using a heavy mulch layer or another method that does not require germination to control erosion, at the close of the construction season.
(7) Techniques shall be employed to prevent the blowing of dust or sediment from the site.
(8) Techniques that divert upland runoff past disturbed slopes shall be employed.
(F) Sediment control requirements shall include:
(1) Settling basins, sediment traps or tanks and perimeter controls;
(2) Settling basins that are designed in a manner that allows adaptation to provide long-term storm water management, as required by the village; and
(3) Protection for adjacent properties by the use of a vegetated buffer strip in combination with perimeter controls.
(G) Waterway and watercourse protection requirements shall include:
(1) A temporary stream crossing installed and approved by the State Environmental Protection Agency, State Department of Natural Resources and/or the United States Army Corps of Engineers if a wet watercourse will be crossed regularly during construction;
(2) Stabilization of the watercourse channel before, during and after any in-channel work;
(3) All on-site storm water conveyance channels designed according to the criteria outlined in the Illinois Urban Manual: A Technical Manual Designed for Urban Ecosystem Protection and Enhancement; and
(4) Stabilization adequate to prevent erosion located at the outlets of all pipes and paved channels.
(H) Construction site access requirements shall include:
(1) A temporary access road provided at all sites; and
(2) Other measures required by the village in order to ensure that construction vehicles do not track sediment onto public streets or washed into the village storm drainage system.
