Impact Justification and Mitigation
1.
Avoidance and Minimization
1 a.
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Stormwater wetland used to mitigate nutrient loading for nitrogen and phosphorus, preventing eutrophication.
1 b.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction
techniques. Installing a sediment barrier (wattles) to protect stream from erosion and sediments.
2.
Buffer Mitigation
2a.
Will the project result in an impact within a protected riparian buffer that requires buffer
mitigation?
❑ Yes ® No
2b.
If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation and
calculate the amount of mitigation required in the table below.

If buffer mitigation is required, is payment to a
mitigation bank or NC EEP proposed?
❑ Yes ❑ No
2d.
If yes, attach the acceptance letter from the mitigation bank or NC EEP.
2e.
If no, then discuss what type of mitigation is proposed.
