Where no natural tree growth exists within ten (10) feet of the street right-of-way, the applicant shall be required to plant street trees in accordance with the following standards:
A. Location
Street trees shall be planted within street rights-of-way along the sides of the street pavement and located within the planting strip as shown in Appendix B.
B. Materials
Trees shall be of nursery stock grown under local climatic conditions. Such trees shall be of desirable stock, such as Honeylocust, London Plane, Oak, Selkova, Bradford Pear and Shadblow.
Trees shall be of symmetrical growth, free of insect pests and disease, suitable for street use and durable under normal maintenance. The average trunk diameter measured at a height of six (6) above the finished grade shall be a minimum of two and one-half (2½) inches. Loam shall be clean, of good quality and such fertility and composition that it will continuously support plant growth.
C. Spacing
Trees shall be planted at a distance of not less than fifty (50) feet and not more than seventy-five (75) feet apart along each side of the street pavement, except as allowed by the Planning Board. At street corners, trees shall not be planted within twenty-five (25) feet of the intersecting right-of-way lines.
D. Tree Pits
The diameter of tree pits (if required) shall be at least six (6) inches greater than that of the root spread; shall have vertical bricked-in sides and shall be at least twenty-four (24) inches below finished grade.
E. Planting
Each tree shall be planted plumb slightly lower than when it stood in the nursery (in relation to the finished grade) and shall be thoroughly watered when the hole is two-thirds (2/3) full of loam. After watering the filling shall be completed and the loam thoroughly stamped. After planting, a three (3) inch mulch of well-seasoned manure or peat shall be applied over the disturbed ground and shallow watering basing provided around the tree.
F. Staking
Each tree shall be double staked in such a manner as to insure maximum stability and to prevent whipping of the tree in high winds. Such double staking shall be accomplished with a pair of two and one-half inches by eight feet (2½" X 2½" X 8') stakes driven plumb two and one-half (2 ½) feet into the ground, and tied at the tops and bottoms with figure eight hitches of #14 gauge wire encased in rubber hose or its equivalent.
G. Maintenance
All trees shall be watered until suitable maintenance is provided by the occupants of the properties.
H. Season Limits
Planting shall be done during the proper seasons. No planting shall be done in frozen soil or during unfavorable weather conditions.
I. Other
Where trees will be subject to more than occasional salt spray and high winds, the more salt-resistant trees such as the Sycamore (a. pseudoplatinus) Maple shall be planted.
