RE: Project Name: 2019 Petition Streets
City of Durham
Dear Ms. Goss,
It was a pleasure talking with you over the telephone last week. As we had discussed we are proposing to
resurface existing gravel roads with asphalt (some include curb & gutter) and provide stormwater improvements
as needed in various locations all over Durham. These roadways will remain open and maintained as gravel
during construction to allow residents/businesses to access their property. We feel that these areas are exempt
from buffer authorization because existing uses are present and ongoing per 15A NCAC 02B .0233.3.b and 15A
NCAC 02B.0267.6. If that is the case we will need confirmation from DWR in writing to obtain our Soil and
Erosion Control Permit from DWQ.
If, however, DWR determines buffer authorization are required we have completed and attached the
appropriate forms for the four (4) streets that are affected.
Please note that the Army Corps has reviewed our project and acknowledged that our project falls under the
Nationwide Permit 3 for maintenance as a non -reporting permit. We have enclosed a copy of the USCE email to
us and have highlighted this response (see email dated March 9, 2018 from Roscoe Sullivan of USCE to Tim
Watson City of Durham).
If you have any questions regarding this application, please contact me at the number below.
Sincerely,
Timothy Watson, PE

Hey Tim,
I have reviewed the information that you submitted concerning the maintenance to the four road crossings outlined in
the email below. Based on your description of the proposed projects and the information that you submitted, I agree
that all of the proposed projects may proceed as non -reporting Nationwide Permit 3 for Maintenance. Please note that
while notification is not required for these projects, the general and regional conditions to the NWP 3 must still be
adhered to.
Please let me know if you need any further assistance.
Best regards,
Ross

Ross,
Thank you for taking the time to discuss the City of Durham's project with me the other day. After our discussion, I
went to our stormwater division and asked about the stream determination you mentioned. They reviewed our
proposed project and based on their experiences these types of modifications have been classified under the NWP-3
Maintenance paragraph (a) as we are not proposing any new impact to any stream.
For clarity I've attached a markup up of our plan with pictures at each of the four locations and ask that you confirm that
we are covered under the NWP-3 permit for maintenance and also confirm that notification is not required as that only
applies to paragraph (b). The photos in the markups were taken on February 22, 2018 after approximately a 1/2" of
rainfall over the previous week.

Location 1: Brunson Street - Upgrading culvert system to accommodate the requirements of the City of Durham
stormwater regulations.
Location 2: Chalmers Street - Realigning culvert system to accommodate the safety of the existing houses that are
located along the existing culvert.
Location 3: Leonard Drive - Upgrading culvert system to accommodate the requirements of the City of Durham
stormwater regulations at both stream locations. (2 pages) Location 4: Omah Street - Adjusting culvert system to
accommodate the requirements of the City of Durham stormwater regulations.
Please let me know if you need any additional information or have difficulty accessing the file.
Thanks,
