Subject: State Stormwater Management Permit No. SW3191101
Cambridge Village Multifamily
High Density Project
Lincoln County
Dear Mr. Miller and Mr. Bailey:
The Division of Energy, Mineral and Land Resources (DEMLR) received a complete, modified State
Stormwater Management Permit Application for the subject project on November 17, 2020. Staff review
of the plans and specifications has determined that the project, as proposed, complies with the Stormwater
Regulations set forth in Title 15A NCAC 02H.1000 amended on January 1, 2017 (2017 Rules). We are
hereby forwarding modified Permit No. SW3191101 dated December 1, 2020, for the construction of the
built -upon areas (BUA) and stormwater control measures (SCMs) associated with the subject project.
This permit shall be effective from the date of issuance until May 18, 2028 and the project shall be subject
to the conditions and limitations as specified therein and does not supersede any other agency permit that
may be required. Failure to comply with these requirements will result in future compliance problems.
Please note that this permit is not transferable except after notice to and approval by the Division. As the
identified developer of the project, North Pilot Knob Road, LLC ("Developer") shall be the designated
permit holder and responsible for meeting the conditions and limitations specified therein.
The following modifications are included and covered by this permit: Relocation of one of the proposed
manholes (MHA-80) & connecting 24-inch reinforced concrete pipes (RCP) and the addition of one new
manhole (MHA-140). These changes were made due to a recently installed Duke Energy power pole guy
wire.
This cover letter, attachments, and all documents on file with DEMLR shall be considered part of this
permit and is herein incorporated by reference. Please replace the previously approved plan sheet with
the attached modified and approved version (Plan sheet C-402).
Please be aware that it is the responsibility of the permit holders, the Developer and BBC Cambridge,
LLC ("Property Owner"), to notify the Division of any changes in ownership and request an
ownership/name change for the stormwater permit. However, if the development agreement between the
Developer and the Property Owner is dissolved, cancelled or defaults, and the Division is not notified by
the Developer to transfer the permit, then the responsibility for permit compliance reverts back to the
Property Owner. A complete transfer request must be submitted to the Division within 30 days as
described below otherwise the Developer and Property Owner will be operating a stormwater treatment
facility without a valid permit which is a violation of NC General Statue 143-215.1. Failure to transfer
the permit may result in appropriate enforcement action in accordance with North Carolina General
Statute § 143-215.6A through § 143-215.6C being taken against the Property Owner.
