Good morning Colleen,
Please find attached the response to your Request for Additional Information.
Let us know if you require any additional information to complete your review. As I mentioned in the USFWS RAI this is a
high priority site so we would like to expedite anything you may need to facilitate permit approval.
Thank you,

Hi Lauren,
I'm reviewing the app for Silverstone, and I have a few questions:
1) It looks like Stream Impacts 10-13 were not included on the previous application. From the impact maps, it
appears these impacts are for riprap. Is this correct?
2) It looks like there should be Mitigation SOAs and/or Completed Compensatory Mitigation Responsibility Transfer
Forms in Appendix D of the PCN attachments, but I'm not seeing them. Can you please submit the Mitigation
forms?
3) The Buffer Determination for this project was performed in 2016, which is more than 5 years ago. It looks like a
couple of the impacts had stream start/stop points associated with them. Are the impacts on Impact Maps CWI-
1.3 & CWI-1.6 completed?
Thanks,

Re: Response to Requests for Additional Information

USACE AID: SAW-2017-02177; DWR #20-0610
(Approx. 158.58 acres)
Wake County, North Carolina
On behalf of Cassa Knightdale II, LLC we are providing a response to the Request for Additional Information
(RAI) emails received on January 14, 2022 for Silverstone, an approximately 158.58-acre site located west
of Hodge Road in Knightdale within Wake County, North Carolina (the Site).
The Impacts Maps attached show the revisions made in June 2020 at the request of the United States Fish
and Wildlife Service (USFWS) and the USACE. The revisions included adding "Permanent No Loss" stream
impacts for riprap added to Impacts 1, 2A, 3A, and 6. The impact maps were approved by the USACE and
DWR in June 2020. In addition, the impact maps have been revised to show directional boring at former
Impact 10A per request from the USFWS on December 21, 2021. This response was sent to the USFWS
and USACE on January 26, 2022. Other than the removal of impact 10A, all impact amounts remain the
same as reported in the Pre -Construction Notification (PCN) application dated 11/15/2021. Additionally, the
Stream and Buffer Mitigation Statements of Availability (SOA's) and payment invoices have been included
in this response.
The comments are outlined below in italics and are grouped by impact, with DWR comments in green. Our
response is below each comment.
1. It looks like Stream Impacts 10-13 were not included on the previous application. From the impact
maps, it appears these impacts are for riprap. Is this correct?
Impacts 10-13 in the PCN (portions of impacts 1, 2A, 3A, and 6 on the Impact Maps) were included
in a revision requested by the USFWS and USACE received on June 3, 2020 in order to better
protect the associated streams from potential erosion. These impacts are "Permanent No Loss"
stream impacts for proposed riprap velocity dissipator pads to be embedded within the stream
channel. Both the USACE and DWR were consulted via phone and email regarding the revision
and no formal revision was required as velocity dissipator pads do not count as a loss. The impact
maps were updated and sent to the USACE and DWR via email on June 23, 2020. A copy of this
email is included in the attachments.

2. It looks like there should be Mitigation SOAs and/or Completed Compensatory Mitigation
Responsibility Transfer Forms in Appendix D of the PCN attachments, but I'm not seeing them.
Can you please submit the Mitigation forms?
Please see the attachments for the Stream and Buffer Mitigation SOAs and mitigation transfer
certificates.
3. The Buffer Determination for this project was performed in 2016, which is more than 5 years ago.
It looks like a couple of the impacts had stream start/stop points associated with them. Are the
impacts on Impact Maps CWI-1.3 & CWI-1.6 completed?
Impact 3A on the impact maps (CWI-1.3, impacts S5, S6, and S12 in the PCN) has been completed.
However, impact 6 (CWI-1.6, S13 in the PCN) has not been completed. The stream associated
with 3A begins at the base of a steep slope, so it is not anticipated to have changed over time.
Please review the updated Impact Maps and contact Lauren Norris -Heflin at [phone] or
[e-mail] if additional information is required.

Timmons Group

Good morning Sam and Stephanie,
Per the request of the USFWS, the site plans have been adjusted to better slow the velocity of flow through the culverts
at the three proposed road crossings.
Our stormwater engineering team reviewed the proposed crossings and made the below plan adjustments to achieve
this. Total permanent impacts have not changed, but an additional 88-ft of permanent, no loss stream impact associated
with dissipator pads has been added. Updated Impact Plans reflecting the adjustments are attached.
Impact #1 - reduced slope from 5.24% to 5.19%; proposed dual 48" RCPs rather than one; culvert outfall
designed with 27-ft of energy dissipator pad as permanent, no loss impact
Impact #2A - reduced slope from 2.13% to 2.10%; proposed dual RCPs of 48" and 42" rather than one 42" RCP;
culvert outfall designed with 28-ft of energy dissipator pad as permanent, no loss impact
Impact #3A - increased proposed RCP from 36" to 48"; culvert outfall designed with 27-ft of energy dissipator
pad as permanent, no loss impact
Thank you,

Thanks for getting this out so quickly!
I forwarded this on and just had a call with the client and engineering team. They're going to look into the logistics of if
they can bring in either request from the USFWS.
I'll reach out if they have an ideas on making it work. We'll probably want to run it by you before revising the plans.
Best,

Hi Lauren,
I hope you're still doing well through all of this. The USFWS reviewed my concurrence request and provided the
following comments:
1. Two of the culverted crossings areas sloped at a very high grade. The plan drawings do not appear to show any
velocity dissipation devices. The Service recommends that the applicant be required to slow the velocity of flow through
the culverted crossings through minimally-impactful methods, such as baffles inside the culverts. Drop boxes may also
be appropriate, depending on the location and function of the stream.
2. In order to avoid and minimize erosion on the project site, the Service recommends that the applicant leave individual
lots vegetated until construction on that particular lot is ready to occur.
I do ask that you provide this information to the design engineer and/or applicant. Please note that I plan to issue the
permit here in just a bit, but considering her comment/request to use velocity dissipation devises, I will put a sentence in
the verification that allows for this type of activity (simply because it is not considered a loss). If there are any changes to
the design drawings/impact lengths, please provide those so I can add the information to our database (it will not
require a new permit submittal).

Please let me know if you have any questions.
Best Regards,
Sam
