Arborist reports for construction are normally required as a condition of Building Permit. The report provides an inventory, assessment and recommendations for tree management during construction.

Arborist supervision of demolition is a permit requirement of some municipalities. It's about working with your demolition contractor to make sure that trees are respected during the activity.

A tree is more than just stem, branches and leaves. It's also roots. A project arborist will make sure that the critical roots aren't destroyed during excavation.  

How hazardous is it? If you have concerns about personal safety from trees it may be a good idea to have them assessed. The decision to retain, mitigate or remove is not always easy.

You manage a large property and multiple stakeholders are involved. You should have a plan in place that enables management of your tree resources over time.

Different situations call for different solutions. It may be a modified landscape installation, a modified building foundation or a reconfigured driveway. Getting it right from the start can make a big difference in the long run.
