In reviewing applications for the subdivision of land, the Board shall consider the following general requirements. In all instances, the burden of proof shall be upon the person proposing the subdivision.
Any proposed subdivision shall be in conformity with the Comprehensive Plan or policy statement of the municipality and with the provisions of all pertinent state and local codes and ordinances.
A. 
Any proposed subdivision may be reviewed by the Board with respect to its effect upon existing services and facilities. The final plan shall include a list of the construction items that will be completed by the developer prior to the sale of the lots and the list of construction and maintenance items that must be borne by the municipality, which shall include, but not be limited to, schools, including busing; road maintenance and snow removal; police and fire protection; solid waste disposal; recreation facilities; and runoff water, disposal drainageways and/or storm sewer enlargement with sediment traps.
B. 
The Board may further require the developer of a subdivision to provide accurate cost estimates to the Town for the above services and the expected tax revenue of the subdivision.
A. 
Depending on the size and location of the subdivision, the Board may require the developer to provide up to 10% of his total area for recreation. It is desirable that areas reserved for recreation be at least five acres in size and easily accessible from all lots within the subdivision.
B. 
Land reserved for park and/or recreational purposes shall be of a character, configuration and location suitable for the particular use intended. A site to be used for active recreation purposes, such as a playground or play field, should be relatively level and dry and have a total frontage on one or more streets of at least 200 feet. Sites selected primarily for scenic or passive recreation purposes shall have access as the Board may deem suitable and shall have no less than 25 feet of road frontage. The configuration of such sites shall be deemed adequate by the Board with regard to scenic attributes to be preserved, together with sufficient areas for trails, lookouts, etc., where necessary and appropriate.
[Amended 11-3-2020 STM by Art. 3]
The Board may require that a proposed subdivision design include a landscape plan that will show the preservation of existing trees (six inches or more), the replacement of trees and vegetation with native species, graded contours, streams and the preservation of scenic, historic or environmentally desirable areas. The street and lot layout shall be adapted to the topography. Extensive grading and filling shall be avoided as far as possible.
[Amended 11-3-2020 STM by Art. 3]
The Board shall not approve for development such portions of any proposed subdivision that:
A. 
Are situated below sea level.
B. 
Are located within the 100-year frequency floodplain as identified by an authorized federal or state agency or, when such identification is not available, are located on floodplain soils identified and described in the National Cooperative Standard Soil Survey, unless the applicant shows proof through the submittal of materials prepared by a professional land surveyor which show that the property in question lies at least two feet above the 100-year frequency flood elevation, not to include filled or made land, or if the applicant presents materials which ensure that:
(1) 
Proposed developments are consistent with the need to minimize flood damage;
(2) 
All public utilities and facilities, such as sewer, gas, electrical and water systems, are located, elevated and constructed to minimize or eliminate flood damage;
(3) 
Adequate drainage is provided so as to reduce exposure to flood hazards;
(4) 
New or replacement water supply systems and/or sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwater and require that on-site waste disposal systems be located so as to avoid impairment of them or contamination from them during flooding; and
(5) 
Construction within the 100-year floodplain conforms to the U.S. Army Corps of Engineers Flood Proofing Regulations.
C. 
Are located on land which must be filled or drained or on land created by diverting a watercourse, except the Board may grant approval if a central sewage collection and treatment system is provided. In no instance shall the Board approve any part of a subdivision located on filled tidal wetlands or filled or drained great ponds (natural bodies of water 10 acres or more in size).
D. 
Employ septic sewage disposal and are located on soils rated poor or very poor by the Soil Suitability Guide for Land Use Planning in Maine (most recent version). Where soils are rated fair for septic sewage disposal, the minimum area of that soil shall be 40,000 square feet.[1]
