Nitrogen-fixing, erosion control plant Sweetfern in critical area and/or buffer zone...good idea?
There is a 20' swath of steeply sloped area in my community with poor, exposed soil and significant erosion. I was considering planting Comptonia peregrina (Sweetfern) at this location. It can tolerate poor soil and is a valuable erosion control plant. Should I be concerned about planting a nitrogen-fixing plant in the buffer zone? What about the critical area? Thank you!

This is not a problem. Many plants in nutrient deficient areas have coping mechanisms, such as nitrogen-fixing. This will not pollute the Bay or waterways.
