The design standards contained in the Rules and Regulations shall govern all development in a conservation cluster development. In addition, the conservation cluster development shall met the following design standards:
A. 
The standards contained in § 198-1803.1.2 through 1803.1.7 and 1803.1.10 and all other sections of the Zoning Bylaws which are not in conflict with these regulations.
B. 
Each building site shall have access by way of a relatively level drive which shall not have a grade in excess of 10%.
C. 
There shall be a buffer strip at least 50 feet wide around the perimeter of the tract when the abutting use is not a conservation cluster development or dedicated open space or dedicated to conservation purposes.
D. 
There shall be a buffer strip at least 30 feet wide between the groupings of building lots within the conservation cluster development.
E. 
Each principal building shall have access from a street:
(1) 
Contained within the conservation cluster development; and
(2) 
Not in existence prior to the development of the cluster.
F. 
No building, structure or pavement shall be located within areas which are required to be maintained as open land.
G. 
Buildings shall be compatible with other buildings in the conservation cluster development.
H. 
Buildings, open spaces, driveways and other development features shall be located and designed in a manner which conforms to the existing natural terrain of the site.
I. 
All existing or proposed utilities shall be installed underground at the time of initial construction.
J. 
The following requirements shall apply to the Open Land that is part of the Development:
[Added 9-21-2021]
(1) 
The minimum required Open Land shall not contain a greater percentage of wetlands as defined in the Wayland Wetlands and Water Resources Protection Bylaw[1] (excluding buffer zones), than the percentage of wetlands found in the overall tract of land on which the cluster development is located.
[1]
Editor's Note: See Ch. 194, Wetlands and Water Resources Protection.
(2) 
The minimum Open Land shall be laid out as one or more parcels that are contiguous with one another and that shall contain at least one access corridor to a public way, or private way open to the public, which corridor shall be not less than 25 feet wide. This requirement may be waived if the Open Land abuts existing conservation land or open space that is otherwise accessible to the public, and through which pedestrian access to the Open Land is feasible and convenient.
(3) 
If the Tract has at least four feet of shared boundary with: (i) existing Open Land; (ii) conservation-restricted land; or (iii) the Mass Central Rail Trail, then the minimum Open Land shall be laid out to abut said adjacent area(s) for at least 25 linear feet, or for the length of the shared boundary if less than 25 feet, and the applicant shall provide walking trail access across the minimum Open Land to said areas from the closest public way and/or from the roadway serving the Development.
(4) 
In order to limit the degree to which the Open Land may have an irregular shape, the following Lot Shape Factor formula shall be used: Lot perimeter squared ÷ Actual Lot area = Lot Shape Factor. Eighty-five percent (85%) of the area of the minimum Open Land shall not have a Lot Shape Factor greater than 50. See examples below:

301 Illustration 2.tif
(5) 
If title to the Open Land is conveyed to an entity other than the Town of Wayland, the grantee's title shall be subject to a "conservation restriction" as that term is used in MGL c. 184, §§ 31 through 33, or an "other restriction held by a governmental body" as that term is used in MGL c. 184, § 26, in either case said restriction shall: (i) preserve the predominantly natural state of the restricted land; and (ii) have a term of enforceability that is either perpetual, in the case of "conservation restrictions," or for 99 years in the case of "other restrictions."
K. 
If a Development contains historic and/or archaeological resources, the Planning Board may require the resource(s) to be protected through the execution and delivery of a preservation restriction that either conforms to the requirements of MGL c. 184, §§ 31 through 33, or otherwise provides long-term protection of the resource.
[Added 9-21-2021]
All improvements not specifically mentioned in the Rules and Regulations or these regulations shall be subject to standards approved by the Planning Board.
