Rain gardens shall be designed according to requirements listed in § 30-440.
c. 
All driveways and paths shall be buffered on both sides by landscaping at least three feet wide. Trees shall be planted to provide shade coverage over at least 25% of all paved areas.

Plant species included on the New Jersey Invasive Strike Team Do Not Plant (updated annually) list of invasive species shall not be permitted.

Retaining walls four feet in height or greater shall require a security fence at the top of the wall.

[Ord. No. O-25-2018, 7-12-2018; amended 8-8-2023 by Ord. No. O-11-2023]
Arbors, trellises, and similar structures may be permitted to extend to eight feet in height, but may occupy no more than 5% of the linear footage of the fencing in total and may occupy no more than six linear feet per instance.
[Ord. No. O-25-2018, 7-12-2018; amended 8-8-2023 by Ord. No. O-11-2023]
a. 
Where required. Street trees shall be required along all existing or proposed public streets within the public realm of a subdivision or site plan, and are in addition to other required plantings as prescribed in § 30-417.
b. 
Number of trees required. The number of trees shall be calculated by dividing the linear footage of frontage and a planting interval of an average of 30 feet on center. (See Article 4B.) The linear footage of frontage shall include the entire frontage and with no exception for driveways, curb cuts or crosswalks.
c. 
Spacing of trees. Trees shall be planted as evenly as is possible given site constraints such as driveways and crosswalks.
d. 
Tree pit design. Tree pits shall provide a minimum of 40 square feet of ground area, be at least four feet wide, and be greater in depth than the existing root ball of the tree to be planted by 1/3. Root barriers shall be placed along the tree side of a sidewalk for a distance of 12 feet, centered on the trunk.
e. 
Characteristics of plantings. Street tree plantings shall be substantially uniform in size and shape and shall have straight trunks.
f. 
Sight triangles. Within sight triangles, a tree may be permitted only with the site-specific approval of the Township Engineer.
g. 
Exemptions. Street tree requirements may be waived by the Planning Board where existing preserved vegetation is considered sufficient to meet these requirements and is reasonably assured of continued survival.
