Bridges shall be designed in accordance with the design standards
of the Massachusetts Department of Transportation.
Planting operations and requirements for trees and plantings
contained herein shall be in accordance with the standards and specifications
of the American Nurseryman Association and the Associated Landscape
Contractors of Massachusetts.
A. Street trees.
(1) There shall be two trees, which may be existing or newly planted,
for each lot in the subdivision.
(2) If trees are existing trees, they must be approved as to health and
suitability by the Tree Warden, and if newly planted they must be
approved by the Tree Warden as to their species, size and location.
(3) No dead, damaged or diseased tree existing as such at the time of
approval of the plan, and no tree injured in the course of work, shall
be permitted to stand on any lot within a subdivision, and upon orders
from the Tree Warden, the subdivider shall remove the same at his
own expense, together with the stump and roots thereof.
(4) A partial list of acceptable types of street trees is included in
the appendix, and categorized according to growth size.
(5) Large-growing trees should be spaced at intervals of 50 feet to 60
feet, medium-growing trees at intervals of 30 feet to 40 feet, and
small-growing trees at intervals of 20 feet to 30 feet. On the side
of the street where overhead wires are present, large- and medium-growing
trees should be planted within the front yard of the individual property
owner, away from such wires.
(6) Where possible, and with the approval of the Tree Warden, the street
trees should be of different varieties. Trees shall be located at
least 10 feet from any underground utilities.
B. Cul-de-sac plantings. With the approval of the Planning Board, the
central radius of a cul-de-sac may be planted with perennial grass
(sod or seed), ornamental shrubs, or retention of existing vegetation.
Suitable mulch shall be used between plants for weed control.
C. Bank plantings.
(1) All cut and filled bankings, or portions thereof, that are susceptible
to eroding or any building lots where fill or excavation has changed
the contours such that drainage to adjoining parcels will be affected
shall be planted with low- or very-low-growing plantings, herbaceous
plants or sod grass (see list in appendix).
(2) Suitable mulch shall be spread liberally for weed and erosion control.
D. Intersection plantings. No small trees, shrubs or herbaceous plants
that tend to obstruct visibility at street intersections shall be
permitted within 100 feet of the point of intersection of the curb
or exterior roadway lines along both sides of the corner lot at the
intersection.
Streetlighting shall be installed along all streets in accordance
with the Electric Light Department's specifications.
Street name signs shall be the standard street name signs made
by the South Hadley Highway Department at the applicant's expense.
Such signs shall be erected by the applicant at each street intersection
near the inside edge of the curb, subject to approval by the DPW Superintendent.
The posts of these signs shall be buried in concrete blocks 10 inches
in diameter and 24 inches in length.
After final approval of all the improvements in the subdivision
and before final release of the performance guarantee, the applicant
shall furnish the Board with two copies (one copy for the Board and
the other for the DPW Superintendent) of an "as-built plan" showing
location and grades of road as built, as well as all utilities as
installed, including inverts of drainage and sewerage systems, and
swing ties at 60° and 120° apart for all ends and intersections
of pipes that are buried. Such plans may be Mylar or linen copies
of the complete set of definitive Plans REVISED into "as-built plans."
After completion of construction and before release of the performance
guarantee, the subdivider shall remove all temporary structures, debris,
surplus materials and rubbish, and shall otherwise leave the area
in a neat and orderly appearance.
