The ordinance provides little in the way of specific activities that are exempt from this ordinance. However; here are some activities where land disturbance that may occur, as a result of that specific activity, has been determined by the Engineering Department to have little to no negative impact to the environment, and the benefits of a formal grading and land disturbance review would be de minimus.
Installing lawn sprinklers, fences, or underground invisible fences
Over-seeding an existing lawn without the placement of additional topsoil
Planting trees or shrubs
Resurfacing an existing bituminous driveway
Replacing a water service connection
Tilling an existing garden
While the ordinance sets the requirements for a grading and land disturbance permit it also provides for some discretion in its application. The ordinance allows the Engineering Department to exempt projects where, in the opinion of the township engineer, the proposed land disturbance will not create a soil erosion problem or adversely affect existing drainage conditions.
This exemption is limited to projects under 2,500 square feet of land disturbance or small additions to existing single-family dwellings. This exemption can only be applied however in the absence of environmentally sensitive areas such as steep slopes, wetland, streams or other bodies of water.
Limited clearing of brush and vegetation including tree / stump removal
Retaining walls less then 4 feet in height
The following activities have been shown to result in sufficient land disturbance that can result in erosion and have the potential to impact existing drainage conditions that they are subject to the requirement of a grading and land disturbance permit.
Expanding or constructing a driveway
Installing a sod lawn
Installing a swimming pool
Installing of a septic system
New building construction
Retaining walls over 4 feet inn height or tiered retaining walls
