[Adopted 4-25-1989]
The Town Board of The Town of Mount Pleasant believes that the preservation of shade trees and similar plantings is of paramount importance in maintaining the quality of life within the town. Trees are recognized as a valued asset, providing a healthier and more beautiful environment in which to live. They provide oxygen, shade, aesthetics and a priceless psychological counterpoint to the man-made urban setting. Trees aid in preventing erosion, siltation of streams and reservoirs, flash flooding and air, noise and visual pollution. Therefore, the following article will deal with regulating the planting, maintenance and removal of trees on both public and private property. The article will also establish a Tree Preservation Council and the office of Town Arborist.
This article shall be known and may be cited as the "Tree Preservation Ordinance of the Town of Mount Pleasant."

A detailed plan to protect and preserve trees before, during and for a period of two years after construction. This shall include a written statement setting forth those steps to be taken to protect trees, roots and crowns from damage during site clearance, excavation, grading, installation of utilities, paving and construction.
(2) 
The above items may be integrated into the normal application requirements and submittals.
C. 
Standards. The approving agency shall apply the following standards in reviewing all development applications and shall attach such conditions and safeguards to any application as are, in its opinion, deemed necessary.
(1) 
Specimen trees, protected trees and specimen tree stands located in the Primary Tree Protection Zone, the Canopy Tree Protection Zones and in the Road Right-of-Way Protection Zone shall be preserved where feasible.
(2) 
Healthy specimen trees, protected trees and specimen tree stands located in the Secondary Tree Protection Zone may be required to be preserved at the discretion of the approving agency.
(3) 
Specimen trees, protected trees and specimen tree stands in the conservation development required perimeter setback shall be preserved where feasible. Additionally, specimen trees, protected trees and specimen tree stands in other sections of the conservation development may be required to be preserved at the discretion of the Planning Board.
(4) 
Prior to the commencement of any development activity on any part of a site, the Building Inspector, Town Arborist and Planning Board shall meet with the developer and his construction manager to ensure:
(a) 
That those trees designated to be preserved are physically identified on the site so as to be easily recognizable as trees to be protected; and
(b) 
That agreed-to measures to protect trees before, during and for a period of two years after construction are implemented.
(5) 
Reforestation plans shall conform to the following:
(a) 
Step 1. Calculate the required density factor for the site (DFS) by multiplying the number of site acres by 15.
Example: A 2.2-acre site has a DFS of 2.2 x 15 = 33.
(b) 
Step 2. Calculate the existing density factor (EDF) of trees which will remain on the site to be protected during construction. Existing density factor is determined by converting the diameter at breast height of individual existing trees to density factor units, using Table 3. These units are then totaled to determine the EDF for site.

Step 3. Calculate the required replacement density (RDF) (Step 2) from the DFS (Step 1).
RDF = DFS - EDF
Example:
RDF = 33 - 21.4
RDF = 11.6
(d) 
Step 4. The RDF can be converted back to caliper inches using Table 4. Any number or combination of transplantable size trees can be used so long as their total density factor units will equal or exceed the RDF.
