[Amended 11-6-2001]
All petitions for the acceptance of a street
by the Town of Wells must be accompanied by a plan showing the boundaries
of such street in conformance with the following standards:
A. Boundary survey. The street boundary survey must be
prepared by a land surveyor registered to practice in the State of
Maine. The survey must conform to the standards adopted by the American
Congress on Surveying and Mapping and the Maine Society of Land Surveyors,
using methods of measurement which will obtain the precision required
on the plan.
B. Monumentation. Class A or Class B monuments must be
set on both sides of the street at every intersection, angle point,
point of curvature, point of tangent, point of compound curve and
point of reverse curve. A Class A monument must be set at the center
of all culs-de-sac. At least four Class A monuments must be set along
each 1/4 mile of street or fraction thereof, preferably at each
end of long tangents. The Road Commissioner may require additional
monuments. Class A monuments must be made of stone or reinforced concrete
and must be a minimum of five inches by five inches by five inches
if square and six inches in diameter if circular and must be at least
36 inches long. A drill hole at least 1/2 inch deep or metal
insert must be placed in the top of each monument to mark the exact
point. All monuments must be set in the ground accurately and properly
backfilled and compacted to minimize any possible disturbance. Class
B monuments must be a metal rod or pipe at least 1/2 inch in
diameter and 36 inches long. In exposed ledge outcroppings, drill
holes at least 1/2 inch deep or metal inserts may be used for
Class B monuments. (Note: Typical Monument Detail is on file in the
office of the Town Clerk.)
C. Ties. If a National Geodetic Survey or Maine State
Coordinate system control point exists within 1/2 mile of any
portion of the proposed street, the survey must be tied to that point.
All intersections with existing streets must be tied in to the nearest
boundary line of record. All monuments must be tied in by measurements
to whatever relatively permanent physical objects, such as structures,
foundations, etc., are available within 200 feet of each monument.
Two reference ties to each monument must be taken when available.
When two ties are not available, reference directions to distant objects,
such as towers or steeples, shall be substituted when those are available.
D. Plans.

durable drafting media, such as tracing cloth, Mylar, herculene or
an equivalent drafting film. Tracing paper is not acceptable. The
scale may be any convenient scale between the ranges of one inch equals
one foot to one inch equals 50 feet that clearly depicts the required
information. The maximum sheet size is 24 inches by 36 inches. If
necessary, more than one sheet may be used. If more than one sheet
is used, all sheets must be appropriately referenced to each other.

and whether found or set as a result of the survey.

reference to the grid system used. The Maine Coordinate Grid System
must be used if a control point is available within 1/2 mile
of any part of the street.
(n)
The direction and lengths of all ties taken
and descriptions of the points to which the ties were taken. Tie measurements
must be shown to the same degree of precision as for the boundary
measurements.
(o)
From one point on the street boundary, show
the direction and length and description of the horizontal control
point tied to, if one is available.
(p)

land on which the street is laid out and the book and page numbers
of deed references.
(q)
