[Ord. No. 5752 §1, 12-8-2011]
This Article shall apply to all real property (including all agricultural, commercial, industrial, office, multi-family and residential property) located within the City of O'Fallon, with the following exemption: It shall not apply to any parcel of land used exclusively for a single-family or two-family dwelling.
[Ord. No. 5752 §1, 12-8-2011]
A. 
Prior To Development. The destruction of more than twenty-five percent (25%) of the trees on any one parcel shall be prohibited. However, where the topography of the land is such as to necessitate extensive grading or filling to make the land suitable for future development, upon grading permit approval, that portion of the parcel of land graded or filled shall be exempted from application of this Chapter for a period of two (2) years, or until it is developed (whichever is earlier) at which time trees so removed shall be replaced at the rate of at least fifteen (15) trees per acre, provided such filled or graded area will be seeded or sodded per City regulations.
B. 
During Development. Once a site plan or preliminary plat approval has been requested, a minimum of twenty percent (20%) of the existing trees or fifteen (15) trees per acre of the entire development (whichever is greater) shall be retained. Existing trees which have been retained will count toward the landscaping requirements set forth in this Code. If some or all trees cannot be retained as provided, these shall be replaced with trees of like or similar kind having a minimum mature trunk caliper four (4) inches and a height of eight (8) feet. Trees should be of a hardwood variety and consistent with the trees referenced elsewhere in this Chapter. Replaced trees shall be properly maintained to insure their survival for a period of at least eighteen (18) months from the date planted.
C. 
Protective Barrier. During development, there shall be erected and maintained, where appropriate, suitable protective barriers around all trees and the drip line so as to prevent damage thereto.
[Ord. No. 5752 §1, 12-8-2011]
Existing trees saved on the site during construction may be credited toward the minimum tree requirements specified for the landscaped open space for each zoning district, except the residential districts. Those existing trees credited shall be a minimum of two (2) inch caliper. Minimum size for existing ornamental and evergreen species shall be six (6) feet in height. All existing plant material saved as a credit toward the minimum tree requirements shall be healthy and free of mechanical injury.
[Ord. No. 5752 §1, 12-8-2011]
A. 
Where site plan application is made for the development or improvement of any non-exempt parcel of land, the site plan shall show:
1. 
The tree protective zone; and
2. 
Trees to be maintained within the tree protective zone, with location for each to be shown with reasonable accuracy and indicate type and size.
[Ord. No. 5752 §1, 12-8-2011]
In the case of emergencies, such as wind storms, ice storms, or other disasters, the requirements of this Chapter may be waived during the emergency period so as not to hamper private or public work to restore order in the City.
