A Greenspace Preservation and Protection Plan shall be provided in accordance with these requirements for all new residential development consisting of five acres and larger. The cumulative acreage of a multi-phased project in excess of five acres and larger shall be subject to these requirements. Additionally, the provisions of this section shall not apply to nonresidential subdivisions or land zoned MF, Multi-family Residential District.
(A) Intent and purpose. The desired outcome is to provide reasonable utilization of the property while achieving the intent and purpose of this Greenspace Preservation and Protection Plan, rather than to maximize the development capacity of the property.
(1) Intent. The intent is to ensure that development is conducted in a manner that is harmonious with the natural environment and maximizes the quality and survivability of retained vegetation.
(2) Purpose. The purpose is to identify those natural features which should be preserved so that development may occur around those features.
(B) Findings. Mount Pleasant Town Council finds and declares the following:
(1) The existing vegetation requirements have resulted in the excessive removal of natural vegetation during land development; and
(2) To remedy these conditions an amendment to these regulations is now necessary; and
(3) These regulations will include a Tree and Topographical Plan which will form the basis of the arrangement of development on the property, as well as additional areas of preservation to ensure the adequate preservation of natural vegetation along street frontage and internal to the development; and
(4) Council now deems these provisions are in the best interest of the citizens of the Town of Mount Pleasant to accomplish these desires.
(C) Specific requirements.
(1) A tree and topographical exhibit is required to facilitate the preservation of valuable existing natural conditions.
(a) A quantitative and qualitative analysis of the natural attributes of the property shall include the existing grade of the property and the quantity and quality of existing vegetation. A plan shall be submitted enumerating the stated attributes at preliminary staff review and sketch plan application.
(b) Applicant shall submit a site analysis with the following information:
1. Property boundaries.
2. Topography showing one-foot contours, ponds, ditches and any other significant natural drainage features.
3. Survey of protected trees with:
A. Illustrated protection zones, and
B. Tree assessment per zoning code requirements.
4. Wetland and critical area delineation, with existing buffers, if applicable.
5. Existing easements.
6. Existing structures, roadbeds and paths.
(2) Additional areas of preservation. The following additional areas of preservation within the proposed development are required based on the factors identified in division (C)(l)(a) and (b) hereinabove:
(a) Street frontage areas of preservation.
1. A minimum 25-foot width natural and undisturbed buffer shall be provided on collector and entry roads (60 feet ROW width or greater).
2. In the absence of existing vegetation replanting is required based on the density and diversity of the representative sampling of 100 square feet (ten by ten) of existing natural vegetation within close proximity to the subject area, comprised of canopy and understory trees and shrubs.
3. Easement treatment. If future utility installation is anticipated, additional area shall be set aside so as not to interfere with the natural and undisturbed buffer. Penetration for utilities should be perpendicular to the buffer and limited to roadway access as a preferred option.
(b) Internal areas of preservation. A suitable amount of natural vegetation shall be preserved within new development based upon the following requirements.
1. Percentage required.
a. For developments where the minimum lot size is less than 10,000 square feet, a minimum of 30% of the developable land shall be set aside for internal areas of preservation, although more may be required based upon site analysis provided by the tree and topographical exhibit. For the purposes described herein, developable land shall not include fresh and saltwater wetlands, retention ponds and rights-of-way.
b. For developments where the minimum lot size is equal to or greater than 10,000 square feet, a minimum of 20% of the developable land shall be set aside for internal areas of preservation, although more may be required based upon site analysis provided by the tree and topographical exhibit. For the purposes described herein, developable land shall not include fresh and saltwater wetlands, retention ponds and rights-of-way.
2. Minimum dimensional requirements. The minimum dimensional requirement shall be that of the zoning district, and not less in size than the smallest building lot shown on plans or plats.
3. Connectivity. Internal areas of preservation shall be integrated amongst the building lots and strategically connected with other greenspace requirements.
4. Planting in the absence of existing vegetation shall be in accordance with the provisions of division (C)(2)(a)2. above.
5. Terraced fill around ponds/wetland areas/buffers is encouraged to meet these requirements.
(D) Street frontage and internal areas of preservation established pursuant to these requirements:
(1) Shall be located on separate lots owned by a homeowner's association.
(2) Canopy trees shall count towards the minimum 160 inches per acre of retained vegetation.
(3) Shall remain in an essentially undisturbed condition except for the following:
(a) Allowed clearing of an eight foot width corridor for the installation of low-impact physical improvements limited to pervious pedestrian trails and pedestrian benches; and
(b) One open recreational field per development no larger than 4,000 square feet to allow for active recreation and neighborhood sports.
(E) Review and approval procedure.
(1) A Greenspace Preservation and Protection Plan conforming to the requirements contained herein shall be submitted at preliminary staff review and sketch plan application.
(2) Staff will review the same for adherence to the stated intent and purpose, with such review forming the basis for a recommendation to the Planning Commission.
(3) The Planning Commission shall approve, disapprove or modify the plan as deemed appropriate.
(F) Appeals from a final decision of the Planning Commission may be filed in accordance with procedures established by applicable law.
