282a Appendix 1 Heritage Tree Selection282b Appendix 2 Michigan Big Trees
A. 
The Township finds that growth and development resulting in increased demand upon natural resources has had the effect of encroaching upon, despoiling and/or eliminating many of the woodlands, trees, and associated forms of vegetation. These resources, if preserved and maintained in an undisturbed and natural condition, provide air quality protection, maintenance of water quality, reduction of flood surges and soil erosion, and protection of vital wildlife habitat. In addition, these resources provide important aesthetic, ecological, recreational and economic benefits to existing and future residents of the Township and must, therefore, be protected.
B. 
Specifically, the Township finds that:
(1) 
Trees and woodland systems protect public health through the absorption of airborne pollutants and generation of oxygen, through the reduction of excessive noise and mental and physical damage related to noise pollution, and through their cooling properties in the summer months;
(2) 
Trees and woodland systems play an important role in the absorption of nutrients, such as nitrogen and phosphorus, from water as it passes from the surface to groundwater tables and lower aquifers;
(3) 
Trees and woodland systems, through their root systems, stabilize the soil and play an important and effective part in soil conservation, erosion control, and flood control;
(4) 
Trees and woodland systems are essential components to the general welfare of the Township, providing natural beauty, natural character, recreational opportunities and wildlife habitat;
(5) 
Protecting this natural resource, and reproductive and regenerative capabilities of trees and woodland systems maintains this heritage for existing and future Township residents;
(6) 
The Township will benefit by instituting a woodland acquisition and tree planting program to protect and replenish trees lost due to development; and
(7) 
The protection of such natural resources is a matter of paramount public concern, as provided by Article IV, Section 52, of the Constitution of the State of Michigan and the Michigan Environmental Protection Act of 1970, MCL § 691.1201 et seq.
The purpose of this chapter is to provide for the protection, preservation and conservation of the Township's woodland systems, natural corridors, heritage trees and protected trees by providing a planting and reforestation and woodland acquisition program, and by managing and protecting the following environmental qualities:
A. 
Ecological. Provide for the protection, preservation, replacement, and proper maintenance and use of woodland systems in order to maintain ongoing natural processes such as water cycling, nutrient cycling, and photosynthesis/transpiration; to minimize disturbance and structural changes to vegetative cover; and to minimize damage from erosion, siltation, windthrow and disease.
B. 
Forestry. Prohibit the unregulated cutting of trees or harvesting of forest products within a woodland; to establish a permit process which will regulate the cutting of trees and harvesting of forest products; and to prescribe the review process for the issuance of tree cutting and harvesting permits.
C. 
Aesthetic character. Protect the Township's woodland systems and trees in order to maintain and improve their current and future visual character, not only for residential areas and homesites, but also as natural settings for development in all zoning districts.
D. 
Conservation. Protect the reproductive and regenerative capabilities of all woodland systems to maintain plant and tree diversity; protect groundwater recharge areas; maintain visual screening, windbreak, dust collection and noise barrier characteristics exhibited by woodland systems.
E. 
Wildlife habitats. Protect the existing woodland systems in the Township in order to limit the loss of existing wildlife habitat, to maximize the quality and quantity of woodland corridors available across the Township, and to encourage habitats suitable for wildlife communities.
F. 
Recreational use. Protect the natural environment of wooded areas in order to provide recreational trail systems linked throughout the Township for pedestrian hiking and other passive uses.
G. 
Rare species habitats. Protect individual trees which are known to be rare within the southeastern area of the State of Michigan, or have reached a certain age of maturity to be considered a landmark specimen or which are known to represent historical value to the community.

If an order to stop is not obeyed, the enforcing agency may apply to the Circuit Court for the county in which the premises are located for an order enjoining the violation of the order, or may take other measures as determined necessary by the Township. A person shall also be required to replace trees removed without authorization by trees equal in dbh to the total dbh of all removed trees. This remedy is in addition to, and not in limitation of, any other remedy provided by law or ordinance, and does not prevent criminal prosecution for failure to obey the law.

A. 
Before development, land clearing, filling or any operation commences for which permission is required by this chapter, the developer or builder shall be required to erect, for the protection of remaining trees, barriers as approved by the Township. Such protection shall remain in its approved location until such time as it is authorized to be removed by the Township, or issuance of a final certificate of occupancy. During construction, no attachments or wires shall be affixed to any trees so protected. Wood, metal or other substantial material shall be utilized in the construction of barriers. Barriers will be required for all trees being protected, except in the following cases:
(1) 
Street right-of-way and utility easements may be ribboned off by placing stakes a maximum of 50 feet apart and tying ribbon, plastic tape, rope, etc., from stake to stake along the outside perimeters of such areas to be cleared.
(2) 
Property areas separate from the construction or land clearing area into which no equipment will venture shall be ribboned off as above [Subsection A(1)].
B. 
Activity to be conducted within the drip line of any tree designated to be retained, including, but not limited to, the placing of any solvents, material or construction machinery within the drip line will be reviewed on a case-by-case basis. Township approval of said activity will be made within five working days and will be based upon degree of impact anticipated. Clean soil may be placed within the drip line of a tree designated to be retained providing that a tree well is constructed that will keep soil at least six feet from the edge of the trunk of the tree. No more that four inches of soil shall be permitted to be placed over the roots of any tree designated to be retained within an area six feet from the edge of the trunk of the tree.

E. 
Variances and appeals shall be granted only in accordance with:
(1) 
Compliance with the strict letter of the restrictions governing use of the property for a permitted purpose or would render conformity with such restrictions unnecessarily burdensome. The showing of mere inconvenience is insufficient to justify a variance or an appeal.
(2) 
The requested variance or appeal can be granted in such fashion that the spirit of the chapter will be observed and public safety and welfare secured.
(3) 
In deciding upon an appeal from an action taken by an administrative official or body, the Zoning Board of Appeals shall determine if the administrative official or body has made an error in any order, requirement, decision or determination in the enforcement and/or interpretation of the chapter.
Administrative costs associated with processing of a building permit, or in processing the subdivision plat or site plan submitted with a building permit, shall be charged to the person per a fee schedule determined by the Grosse Ile Township Board of Trustees.
