Hi Mary,
Per the RPOT file, you're the 401 PM for this site. Please see below as an FYI for the above mentioned project; I forgot to
copy you.

Good afternoon,
I have completed my review of the above referenced application and have the following questions/comments. Please
provide one consolidated response. If you have any questions, let me know.
General:
1. Could you please provide the T&E report that was sent to USFWS?
2. The Corps believes this project is more appropriate to verify under NWP 42.
a. Can you confirm discharges at this location will comply with part "C. Regional Conditions Applicable to
NWP 42" (i.e. will not result in above -grade fills that will result in an increased water surface elevation)?
If they do, a "no -rise" certification from FEMA should not be necessary.
3. Please provide revised impact sheets where the area of grading/fill within wetlands is visually depicted on the
plan sheet and profile. Using colors can be helpful for this. There's a lot of linework making it difficult to see
impacts clearly.
4. Per the notation on the Wetland Data Sheets, please include a site map showing the sampling point locations.
Please also include the location of the enclosed photos on the map. We're starting to request that a figure like
this be included in all JD requests.
Regarding impacts proposed under NWP 14:
5. On some sheets, a Temporary Construction Easement (TCE) is within a wetland. Are temporary impacts
anticipated in these area?

6. Can you confirm the boardwalks will be elevated at least 3 feet to allow for high flow events?
7. Can you elaborate on the purpose and need for wetland fill/grading for Wetland Impacts 1, 3 and 4? Why can
boardwalks not be used, or the limits of disturbance be shifted slightly, to avoid impacts to these areas?
a. For example, Wetland Impact 3 shows impacts due to grading. Why does the fill line 'jut out' in these
areas causing the impacts? Could you provide an additional plan view sheet showing the grading details
with the existing wetland/grades and subsequent grading areas clearly depicted?
8. Regarding Wetland Impacts 5 and 6- Mechanized clearing, including the stumping of trees to facilitate the noted
topsoil removal, is considered a permanent conversion impact.
i. Why is the clearing area so extensive for Wetland Impact 5?
ii. Please note since this would be considered a permanent impact, you would exceed the
mitigation threshold for this project and the Corps will require evidence of mitigation credit
availability for this project. Conversion impacts can be mitigated for at a 1:1 ratio.
9. Do the swale bridge details outlined on Sheet C-7.0 correspond to the bridges shown on sheet C-4.10 and C-
4.15? If so, the concrete footers and associated temporary shoring need to be accounted for in the wetland
impacts. Otherwise, please provide bridge details for the bridges with footers in wetlands.
Regarding impacts proposed under NWP 13:
10. Are proposed impacts within a riffle/pool complex?
11. Is the proposed discharge greater than an average of one cubic yard per running foot below the OHWM?
a. To process this under the NWP 42, please provide the acreage of impacts below the OHWM due to
these activities.
12. On Sheet C-4.10, does the 58 LF of bank stabilization refer to both sides of the bank? The arrow on the plan view
only points to one side, but stream grading is called out on both sides of the profile view. Should the profile view
call out on the right be for wetland grading? The riprap fill is also not depicted, only grading. Could you provide
a profile view that includes where the rip rap is being placed and indicates the wetland fill/grading impacts as
well?
Thank you,
Amber

Hey Amber,
This shapefile shouldn't have any fill within the project boundary. Let me know if you need anything else!

Good morning Taylor,
Could you please provide a shapefile of the project area? Since this is a long, linear project having one will help
streamline my review.
Thanks,
