During the Construction or Land Preparations Phase

Mark and Identify Preserved Trees: If you expect to preserve trees, be sure they are clearly marked on the plan and your desires are clearly communicated to contractors. Build temporary fences of brightly colored or flagged material so that construction workers can clearly see zones from which equipment must be kept clear.

Identify the Critical Root Zone: Modern construction equipment can quickly damage tree bark or compact soil to the point where your valuable trees’ roots are depleted of oxygen and moisture. Make sure that no one operates equipment within the critical root zones of trees you are trying to preserve. Erect protective fencing around the critical root zone prior to clearing. Signage is highly recommended to communicate “No Entry” areas.  This area needs to be protected and not compromised by equipment traffic, grading changes, utility trenching, or toxic material storage.  See illustration below for details.
