
Right-of-way width: 66'
Cartway width: 40'
Sidewalk width: 13' each side:
o most common: 4' street lawn/ 9' ped. walkway
o several locations: no street lawn (all sidewalk)
Street parking: parallel, along length of corridor, both sides
Utility poles:
o along length of corridor - along southerly side of street
o not located along north side of corridor
o poles and wires generally within street lawn (first 4 feet from curb)
o various cross-street wires
Zoning - building permitted at streetline (0' front setback)
Factors






Width of the street lawn (i.e., lawn area between sidewalk and curb)
o affects size of tree (see guidelines in "Trees for New Jersey Streets")
Lack of street lawn (tree grate) - affects tree selection
Setback of building - width of sidewalk
o affects tree selection (particularly branching pattern)
o building at street line encourages columnar branching, discourages broad-spreading
branching
Presence/non-presence of power lines
o depending upon location encourages: low-growing trees to stay below the lines or
columnar branching when not planted under
Building/ sign placement
o tree selection and placement should minimize obstruction of view to retail
signs/storefronts
Pedestrian compatibility
o high and/or narrow branching pattern so as not to impede pedestrian movements
Other factors
o tolerance of urban conditions; salt tolerance; lack of fruit/thorns; low water demands;
tolerant of limited root zones
Hardiness Zone: 6b
Summary Key Consideration:
o Width of sidewalks and zero building setback limits choice to trees with mature spread of
about 20 feet (10 feet each side), along both sides of corridor
o Must be utility pole friendly along south side of street (smaller trees - generally less than
25' mature height)
o
o
Consistency of trees north-sides - if utility wire friendly trees required along south sides,
consider along north side as well for streetscape consistency
High and/or narrow branching pattern so as not to impede pedestrian movements
