Stone or current standard steel rod monuments shall be set at all
corners and angle points of the development boundaries where the interior
angle of the subdivision boundaries is 135° or less.
Stone monuments shall be a minimum of four inches square at the top
and four feet in length. After they are set, drill holes 1/2 inch
deep shall locate the point or points described above.
When a development is to be served by a central water supply system,
the complete supply system, including any required fire ponds and
dry hydrants, shall be installed at the expense of the subdivider.
If a central water supply system is provided by the developer, the
location and protection of the source as well as the design, construction,
and operation of the system shall conform to the standards of the
Maine Rules Relating to Drinking Water (10-144 CMR 231).
The Board may waive the requirement for fire ponds only upon the
submittal of evidence that the soil types in the development will
not permit their construction or upon certification from the Fire
Chief that a sufficient water supply exists in the area.
The developer shall submit evidence of soil suitability for each
lot for subsurface sewage disposal prepared by a Maine licensed site
evaluator in full compliance with the requirements of the State of
Maine Subsurface Wastewater Disposal Rules.
On lots in which the limiting factor has been identified as being
within 24 inches of the surface, a second site with suitable soils
shall be shown as a reserve area for future replacement of the disposal
area.
In no instance shall a disposal area be permitted on soils or on
a lot which requires a new system variance from the Subsurface Wastewater
Disposal Rules.
Where a development is traversed by a stream, river, or surface water
drainageway, or where the Board deems that surface water runoff to
be created by the development should be controlled, there shall be
provided easements or drainage rights-of-way with swales, culverts,
catch basins or other means of channeling surface water within the
subdivision and over other properties. This stormwater management
system shall be designed by a registered professional engineer.
Drainage easements for existing watercourses or proposed drainageways
at least 30 feet wide, conforming substantially with the lines of
existing natural drainage, shall be provided and indicated on the
plan.
The developer shall provide a statement from a qualified professional
engineer that the proposed development will not create erosion, drainage
or runoff problems either in the development or in other properties.
Where the peak runoff from the development onto other properties
is increased either in volume or duration, easements from the abutting
property owners allowing such additional discharge shall be obtained.
A stormwater drainage plan, showing ditching, culverts, storm drains, easements, and other proposed improvements, meeting the standards of Article XVII shall be submitted.
