Permeable surface material being fitted to trees in Market Square

May 22, 2019

Public Works crews are currently placing new, permeable surface material around trees in front of the new Tuscan Market as well as the North Church. The permeable surface around this tree is made from recycled materials. The surface is highly porous, allowing approximately 5,800 to 6,300 gallons of water to pass through per hour, per square foot. This greatly reduces water runoff, and allows the trees to uptake more water throughout the year. This material also minimizes compaction in the root zone of the tree, and does not allow trash to pass through.
