About this detail

The assembly is set within a specialty paving sidewalk adjacent to a granite stone curb and asphalt street. A compacted soil pedestal supports the root ball over a compacted or undisturbed subgrade, with the surrounding tree pit backfilled with planting soil in three to four inch lifts. Eighteen-inch injection molded root barriers contain the pit edges alongside metal edging and steel angle iron supports or tray systems. An ADA-compliant iron tree grate with a raw steel finish covers the continuous tree soil. Two pressure-compensating drip bubblers are installed for each street tree, accompanied by a three-inch high soil saucer tapering to zero inches at the root flare and topped with two inches of organic mulch.
