NPDES stands for National Pollutant Discharge Elimination System.  It is a federal program out of the Environmental Protection Agency (EPA) that regulates pollution through permits.

It can be helpful to work on a stream buffer delineation before submitting a plan for review. This would not be considered a review, so a comment letter would not be produced, and official approval could not be granted until a full plan submittal had been received and reviewed.

Any disturbance over 5,000 square footage or 100 cubic feet needs a grading permit.

The purpose of a landscape code is the aesthetic and environmental enhancement of new development.
