Planters are not just for plants. The best tree locations are often the best locations
Compromise is possible...
Local parking lot shading requirements can force dense tree planting. Where trees
must be pushed aside to make room for lights, those on the edge of a lot are less
critical than those in a finger or island planter. This is because most agencies
give twice as much shading value when all sides of the tree overhang the parking
The choice of tree species, relative to light pole heights, can allow reduced clearances.
The trees at right will develop large, open canopies when they mature, with most
of the foliage held above the lights.
With the right tree, a mid-height light can be as close as half the drawn canopy
Trees on the Land-scape Architect’s drawings are usually shown at about 15-20 years
of age. A short to mid-height light standard, outside the canopy as drawn, will
remain relatively unobstructed. For information about mature sizes, visit the Tree
A taller light standard should have about 25% more clearance to avoid long term conflicts.
