Whenever new construction is proposed, the preparation of a boundary and topographic survey will assist a designer in determining the location, size and height of proposed improvements. Whenever it is desired to save as many trees as practical, it is advised to add a tree survey to the above. This can be done in accordance with a landscape ordinance or, if no ordinance governs the property, it can be limited to just the size and/or species of trees you desire to have identified.
