Tree Protection During Construction

How to Protect Trees During Construction

It is essential to provide extra care and protection for your trees during construction. Tree protection fencing established at or beyond the tree drip line is the best way to protect the valuable resource of trees. Fencing will alert all workers that they cannot disturb the area within the fence, thereby protecting the ability of the roots to obtain air, water, and nutrients. Fencing will prevent driving, parking of equipment, storage of construction supplies, dumping of waste or fill dirt, or grade changes within the drip line. Please contact the Land Use and Planning Division for effective mitigation measures and other "best construction practices" regarding trees. Also, see the handouts below for important information about protecting trees during construction.
