April,

In response to your request for additional information on April 14th, 2022 regarding SAW-2021-02598 (Woodland Church Road S/D), I have answered your comments below:

1. The project proposes to discharge fill material into 0.037 acre of wetlands. Please provide additional information regarding avoidance and minimization. Specifically, please explain
why the road could not be shifted to further reduce impacts.

a. Due to nutrient reduction requirements for runoff on site (Falls Lake Watershed), the majority of the future developed area must be treated by stormwater control measures (SCMs).
The eastern portion of the site drains to the convergence of stream “SA” and stream “SB”, and the most suitable location for an SCM (and a road crossing) within that drainage catchment
is the gently-sloped area North of the convergence. The proposed route for the road was designed with both the potential SCM and the existing wetland in mind. A reverse curve design
for the road crossing (curves South to cross stream “SA”, the back North to cross stream “SB”) prevents a straight road cut through the center of wetland “WB-2” while maintaining space
above the road for the SCM. NCDOT requires at least 100 ft. of straight road between reverse curves, so any rotation of the road to avoid impacts to Wetland “WB-2” lengthens the curve,
and causes most of this road section to move North. Shifting the road further North will likely not give enough room to locate the SCM here in order to capture all the road runoff.

I’ve attached the Grading and Drainage plan with a rough mark-up to show how rerouting the road would cause a reduction in space for the required stormwater device as described above.

2. Given the proximity of this project to known populations of several threatened/endangered species, we will initiate informal consultation with the US Fish and Wildlife Service (USFWS).
Please note that the Corps cannot verify the use of an NWP until Section 7 consultation is complete.

a. This comment is noted. It is understood that verification from USFWS is necessary prior to proceeding with the NWP for these stream crossings.

Let me know if you need any clarification on these responses.
