Additional landscape standards.
(1) 
Street trees along private roads shall be located between the curbline and the proposed sidewalk. Street trees in this location are more conducive to traditional town planning principles, will aid in the separation of vehicular and pedestrian circulation patterns, and will create a safety zone for those pedestrians. To minimize interference with sidewalks and utilities, tree species should be chosen based on root characteristics; with respect to underground utilities, tree spacing adjustments and/or tree relocation may be permitted by the Township Engineer. Species with extensive surface roots should be avoided. In addition to the trees listed in Section 2 of Appendix B,[1] the following trees may be used as street trees in a TND:
Acer griseum
Paperbark maple
Carpinus betulas "fastigiata"
Pyramidal european hornbeam
Koelreuteria paniculata
Goldenrain tree
Ostrya virginica

In these areas, plantings may be reduced, provided the intent of the chapter is met.
(3) 
Site element screen shall be provided in accordance with § 425-500F.
