Betsy, 

I have attached to this email 401 General Water Quality Certification 4134 (GC4134), which corresponds to US Army 
Corps of Engineers Nationwide Permit 13. GC4134 allows up to 500 feet of stream impacts for bank stabilization projects 
on WS‐IV streams when natural techniques (e.g. sloping, vegetation, geolifts) are used without requiring written 
approval from the Division assuming all conditions of GC4134 will be met. This means, based on your description of the 
project, the owner would be covered under GC4134, but would not have to submit any paperwork to our office, or 
receive approval from our office. 

Let me know if you have any questions.

Good Morning Andrew!  

I talked with David Brown.  He said we would need to get the Nationwide 13 permit for the project described 
below.  Would I also need a permit from DEQ as well?

I am working on a concept design for a home owner who has a small stream thru their back yard. We are looking at 
expanding the flood bench to about 4ft on each side and then sloping to existing grade at a minimum of 3:1. This would 
give the main stream a minimum of 12ft flood stage width. Over the past year, a small bench has naturally formed in 
one area.  We look to model this throughout the site (picture included). This site doesn't have very high banks so I 
expect the side slope to be fairly low. Grass and other native vegetation will be installed. The project encompasses about 
350 ft of stream bank. This includes about 175 ft on both sides of main stream and about 75 ft on one‐side of a small 
tributary. We do not anticipate any activity in the stream or below the bench elevation. Attached are a few photos and a 
general sketch. Location details below. 

Location:  35.352606°, ‐82.523279° 
Marston Creek, Class WS‐IV 
Drains into Mill Pond Creek and then into French Broad River 

Thanks for the help.  
Have a great day.  

Betsy.
