Getting Started

There are several situations when a project would require a site development permit:

  1. Clearing - For cutting or removal of vegetation which results in exposing any bare soil.
  2. Grading - For earthwork, excavation or filling in excess of 10 cubic yards.
  3. Tree Cutting - For tree cutting on slopes with gradients which exceed 25% when more than five trees of six-inch diameter are to be cut or the area to be cleared is greater than 2,500 square feet.
  4. Private Right-of-ways - For construction of streets, alleys, common greens and pedstrian connections located within a private right-of-way.
