Subject: Stormwater Permit Renewal/Ownership Change
Stormwater Management Permit SW7951201
Hunters Landing Apartments
New Bern, NC, Craven County
Dear Mr. Tarbell:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SV 7951201 for a stormwater treatment system consisting of a wet
detention pond serving Hunters Landing Apartments located on Racetrack Road in New
Bern, NC expires on August 8, 2022. Renewal applications were due 180 days prior to
expiration. A review of the Craven County tax records shows that the property is
currently owned by EWT 45, LLC.
The Coastal stormwater rules and the NC General Statutes require a stormwater permit
for this project. Stormwater permits are not automatically transferred when property is
sold. The stormwater permit was originally issued to Equity Housing Fund IX
Partnership. Please submit a completed permit renewal application and a stormwater
ownership transfer application along with a separate $505.00 processing fee for each
application.. Permit application forms for renewal and ownership transfer can be found
on our aver site at: https://deg.nc.c�ov/about/divisionsienergy-mineral-and-land-
esources/stormwater'stcrrnwiater-orogram/post-construction-program/permit-transfers-
renewals. North 3arolina General Statutes and the Coastal Stormwater rules require
that this properly be covered under a storrnwater permit. Failure to maintain a permit
subjects the per-1 ttee and landowner to assessment of civil penalties.

Re: Permit Renewal

Dear Al,
Please find attached for you review and approval two(2)copies of the modification plans and
pipe sizing calculations for proposed modifications to the above referenced stormwater permit.
Per the attached correspondence documents this project is currently going through the renewal
process. As you are aware we were not able to provide Engineer's Certification for this project,
as field inspection indicated that it was not currently within the permit specifications.
In order restore this project to be within permit compliance,we will need to make the following
changes as indicated on the plans:
1) Pipe Drainage Area#2,which is the portion of the project currently transported offsite
without passing through the wet detention basin,to the wet detention basin. We propose
piping into the back side of the pond with a rip rap pad. This pond does not have a
forebay,therefore we don't see this as being a concern.
2) Raise the outlet PVC to raise the permanent pool elevation as per the detail. This will
ensure that the permitted permanent pool area is satisfied.
Please review and let me know if you have any questions,concerns or need revisions made to this
set. It is my understanding that the renewal fees of$505.00 has been submitted. If approved,we
will begin construction of these proposed modifications as soon as possible.
Thank you,
BW7
