The root systems and branches of trees and brush may cause problems if they grow too close to foundations, power lines or underground utilities. Just like a house, the natural foliage on a building site must be maintained and cared for properly.

Important Considerations for Landscapes:

• The property may have distinct features that contribute to the historic significance of the building. Assess the property carefully and look for things like purpose-built gardens, outbuildings or elements of structure that may need preserving;
• The ground around a building should slope away to encourage water drainage. Over long periods of time as streets and sidewalks are built up, the original grading of the property may not be draining properly. This will need correcting with new sloping of the grade and/or creation of swales on the property;

• Large trees that are close to a building may cause damage if root systems have grown around the foundation or if the trees are rotting. Branches may also need pruning or removal if they are interfering with electrical lines or roof structures. Consult with tree removal or arborist professionals;
  
• Property markers may not be easy to find, especially if the landscape has been altered or overgrown. Surveyors would often use markers called "SIBs" or Standard Iron Bars to pinpoint the corners of a lot. It may be necessary to re-survey a property to delineate exact boundaries. Consult with local municipal officials to see if surveys exist for the lot you're working;
  
• Historical plaques may be placed on the property that describe the building, the date or style of construction or an important event. These markers may mean that the building has historical status and may be protected.
