Frequently Asked Questions

When do I need to obtain a grading permit?

Grading is complicated. It is always advisable to consult with a registered professional (architect or engineer) prior to grading. In general, 50 cubic yards of cut or/and fill, or 3 feet of fill or 2 feet of cut requires a grading permit. No grading or grubbing should be done within 50 feet of a creek or stream. No riparian vegetation (such as willow, cattails or other such vegetation) should be removed from a creek, stream or wetland. There are many other standards, so please consult with a registered professional or contact the Department of Planning & Building first.
