Watauga County
Dear Deron Geouque:
The Raleigh Central Office received a complete, State Stormwater Management Permit
Application for the subject project on May 9, 2022. Staff review of the plans and specifications
has determined that the project, as proposed, complies with the Stormwater Regulations set forth

Permit No. S W4220501 dated July 28, 2022, for the construction of the built-upon areas (BUA),
vegetated conveyances and stormwater control measures (SCM) associated with the subject
project.
This permit shall be effective from the date of issuance until July 27, 2030 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

In compliance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations promulgated and
adopted by the North Carolina Environmental Management Commission, including 15A
NCAC 02H.1000 amended on January 1, 2017 (2017 Rules) (the "stormwater rules"),
PERMISSION IS HEREBY GRANTED TO

construction, management, operation and maintenance of built-upon area draining to two
ADS Bayfilter systems ("stormwater control measures" or "SCMs") discharging to Class
B;TR;HQW waters as outlined in the application, approved stormwater management,
supplement, calculations, operation and maintenance agreement, recorded documents,
specifications, and other supporting data (the "approved plans and specifications") as
attached and/or on file with and approved by the Division of Energy, Mineral and Land
Resources (the "Division" or"DEMLR"). The project shall be constructed, operated and
maintained in accordance with these approved plans and specifications. The approved
plans and specifications are incorporated by reference and are enforceable part of this
permit.
This permit shall be effective from the date of issuance until July 27, 2030 and shall be
subject to the following specified conditions and limitations. The permit issued shall
continue in force and effect until the permittee files a request with the Division for a permit
modification, transfer, renewal, or rescission; however, these actions do not stay any
condition. The issuance of this permit does not prohibit the Director from reopening and
modifying the permit, revoking and reissuing the permit, or terminating the permit for
cause as allowed by the laws, rules, and regulations contained in Title 15A NCAC 2H.1000
and NCGS 143-215.1 et.al.
1. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is
185,012 square feet. The runoff from all BUA within the permitted drainage area of
this project must be directed into the permitted SCM. The BUA requirements and
allocations for this project are as follows:

a. SCM BUA LIMITS. The SCM labeled System A has been designed using the runoff
treatment method to handle the runoff from 163,350 square feet of BUA within
the delineated drainage area. The SCM labeled System B has been designed using
the runoff treatment method to handle the runoff from 21,662 square feet of BUA
within the delineated drainage area. The pipe collection network for both systems
has been oversized to provide additional underground detention prior to reaching
the Bayfilter Systems.. System A and System B do not contain any allocation for
future BUA.
2. PERVIOUS AREA IMPROVEMENTS. At this time, none of the pervious area
improvements listed in G.S. 143-214.7(b2) or the Stormwater Design Manual have
been proposed for this project. Pervious area improvements will be allowed in this
project if documentation is provided demonstrating those improvements meet the
requirements of the stormwater rule.
3. SCM REQUIREMENTS. The SCM requirements for this project are as follows:
a. SCM DESIGN. The SCM is permitted based on the design criteria presented in the
sealed, signed and dated supplement and as shown in the approved plans and
specifications. This SCM must be provided and maintained at the design condition.
4. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not
cause erosion downslope of the discharge point.
S. VEGETATED SETBACKS. A 30-foot wide vegetative setback must be provided and
maintained in grass or other vegetation adjacent to all surface waters as shown on the
approved plans. The setback is measured horizontally from the normal pool elevation
of impounded structures, from the top of bank of each side of streams or rivers, and
from the mean high waterline of tidal waters, perpendicular to the shoreline.
6. RECORDED DOCUMENT REQUIREMENTS. The stormwater rules require the
following documents to be recorded with the Office of the Register of Deeds:
a. ACCESS AND/OR EASEMENTS. The entire stormwater conveyance system,
including any SCMs, and maintenance accesses must be located in public rights-of-
way, dedicated common areas that extend to the nearest public right-of-way,
and/or permanent recorded easements that extend to the nearest public right-of-
way for the purpose of inspection, operation, maintenance, and repair.
b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance
agreement must be recorded with the Office of the Register of Deeds.
c. FINAL PLATS.The final recorded plats must reference the operation and
maintenance agreement and must also show all public rights-of-way, dedicated
common areas, and/or permanent drainage easements, in accordance with the
approved plans.

7. CONSTRUCTION. During construction, erosion shall be kept to a minimum and any
eroded areas of the on-site stormwater system will be repaired immediately.
a. PROJECT CONSTRUCTION, OPERATION AND MAINTENANCE. During
construction, all operation and maintenance for the project shall follow the
Erosion Control Plan requirements until the Sediment-Erosion Control devices are
converted to SCMs or no longer needed. Once the device is converted to a SCM, the
permittee shall provide and perform the operation and maintenance as outlined in
the applicable section below.
b. SCM RESTORATION. If one or more of the SCMs are used as an Erosion Control
device and/or removed or destroyed during construction, it must be restored to
the approved state stormwater design condition prior to close-out of the erosion
control plan and/or project completion and/or transfer of the state stormwater
permit. Upon restoration, a new or updated certification will be required for the
SCM(s) and a copy must be submitted to the appropriate DEQ regional office.
8. MODIFICATIONS. No person or entity, including the permittee, shall alter any
component shown in the approved plans and specifications. Prior to the construction
of any modification to the approved plans, the permittee shall submit to the Director,
and shall have received approval for modified plans, specifications, and calculations
including, but not limited to, those listed below. For changes to the project or SCM
that impact the certifications, a new or updated certification(s), as applicable,will be
required and a copy must be submitted to the appropriate DEQ regional office upon
completion of the modification.
a. Any modification to the approved plans and specifications, regardless of size
including the SCM(s), BUA, details, etc.
b. Redesign or addition to the approved amount of BUA or to the drainage area.
c. Further development, subdivision, acquisition, lease or sale of any, all or part of
the project and/or property area as reported in the approved plans and
