Trimming debris can contribute to stability problems by smothering vegetation and by causing damage to the slope in sliding or rolling downhill. It is difficult to offer general recommendations for dealing with this material due to the wide range of site characteristics and debris volumes that might be generated. Since regulations regarding the disposition of trimming debris vary it is advisable to check with local planning or engineering departments for advice. Disposing of bluff top clearing debris over the edge of a slope will be discussed later in the guide. Do Not Remove Trees Without Cause.
People tend to remove many more trees than are necessary during site preparation.
The value of a healthy, strong tree on a slope or bluff far outweighs its value as lumber or firewood. A tree should be retained unless it is a hazard to life or property, is growing on the proposed house site or drainfield area or has some other major problem. Do not clear a reserve drainfield area before it is needed. Explore alternatives to removal thoroughly before deciding to cut. The location of trees and other factors involved should be considered carefully.
