(A) NEW CONSTRUCTION.
(1) All construction, development, and redevelopment projects with land disturbances equal to or greater than one acre, including sites, which disturb less than one acre, but are part of a larger common plan of development, must, at the time of application to the Village, submit:
(a) A Notice of Intent permit issued by EPA.
(b) A Stormwater Pollution Prevention Plan (SWPPP) including Best Management Practices to prevent stormwater discharge in accordance with EPA NPDES Phase II regulations for construction site stormwater runoff control.
(2) The stormwater pollution prevention plan shall outline the BMPs to be undertaken by the operator/owner of the project to protect stormwater quality during the construction phase of the project.
(a) These BMPs shall be maintained by the owner of the property. Inspection of these BMPs shall be made at a minimum once a week by the owner and a log of this inspection shall be kept on-site for review by the Village. The Village shall also inspect these BMPs on a periodic basis. These BMPs shall be subject to the approval of the Planning and Zoning Department.
(3) Construction and development sites must control and properly dispose of construction wastes, trash, chemicals, etc.
(B) POST CONSTRUCTION.
(1) All development and redevelopment projects with land disturbances equal to or greater than one acre, including sites which disturb less than one acre but are part of a larger common plan of development and all construction of additions to buildings or of outbuildings over fifty percent (50%) of existing Floor Area Ratio, must submit a Grading and Drainage Plan with a Certified Engineer’s stamp showing on-site water retention ponding volumes.
(2) For all development and redevelopment projects with land disturbances equal to or greater than one acre, including sites which disturb less than one acre but are part of a larger common plan of development, and all construction of additions to buildings or of outbuildings over fifty percent (50%) of existing Floor Area Ratio within the Village, post construction water quality BMPs are required. This requirement is in addition to any other requirements that may apply. These BMPs shall be subject to the approval of the Planning and Zoning Department.
(3) Contractors or developers must complete the on-site water retention ponding, berming, banking, ditching, or underground retention system prior to receipt of Certificate of Occupancy or in case of subdivision, sales of lots to the public.
(4) Maintenance responsibility of stormwater control is the responsibility of the property owner up to the point where stormwater enters public facilities.
(5) Where a site development, building permit, a major or minor subdivision, or a replat alters the elevation or location of any designated 100-year floodplain, as shown on current FEMA flood insurance rate maps, the developer shall be required to provide to the Village all necessary data needed to effect the flood boundary revision or amendment. Any required fees for processing shall be the responsibility of the developer.

(C) STORMWATER DISCHARGE FROM INDIVIDUAL PARCELS.
(1) The discharge of nuisance waters from private property to public streets is prohibited. Arterial and collector streets shall be protected from damages to the surface and from the safety hazard created by surface flow of nuisance waters across them.
(a) Parking lots, yards, open fields, landscaped areas, developed and undeveloped lots shall be bermed, banked, ponded, ditched, or otherwise contoured for on-site water retention to prevent stormwater runoff onto Village streets and roads or ditches.
