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
NC Department of Natural and Cultural Resources, Division of Parks & Recreation
Hammocks Beach State Park Mainland Development — Phase 1
1572 Hammocks Beach Road, Swansboro, Onslow County
FOR THE
construction, management, operation and maintenance of built -upon area (BUA) for a 12% low
density project (the "low density area") discharging to Class SA-HQW waters as outlined in the
application, approved stormwater management plans, supplements, 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 parts of this permit.
This permit shall be effective from the date of issuance until rescinded and shall be subject to the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, 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 15A NCAC 2H.1000
and NCGS 143-215.1 et.al.
BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 350,000
square feet. The BUA requirements and allocations for this project are as follows:
a. LOW DENSITY AREA BUA LIMITS. The low density area must not exceed 12% per the
requirements of the stormwater rules. Within this low density area, this permit approves a
percent BUA of 4.54% and the construction of a total of 350,000 square feet of BUA, which
includes 215,450 square feet of future BUA.
b. CAMA AECs. Where a project or lot is located within CAMA's Area of Environmental
Concern (AEC), the Division of Coastal Management (DCM) may calculate a different
maximum BUA based on CAMA regulations. The more restrictive BUA limit will apply to the
project.
2. PERVIOUS AREA IMPROVEMENTS. The following types of improvements are included in the
project and considered pervious per the stormwater rules:
Page 1 of 5

State Stormwater Management
Permit No. SW8 200811
a. PERVIOUS WALKING TRAILS. A 6-foot and 10-foot wide unpaved walking trail located
throughout the project has been demonstrated to be a pervious surface. The underlying soil
must not be mechanically compacted prior to installation. If, in the future, this walking trail is
found to no longer be pervious, a permit modification will be required.
3. LOW DENSITY AREA REQUIREMENTS. The low density area requirements for this project are
as follows:
a. LOW DENSITY AND CONVEYANCE DESIGN. The low density area 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 low density area and conveyances must be
provided and maintained at the design condition.
b. PIPING. Other than the piping shown on the approved plans, only minimal amounts of
piping under driveways and roads is allowed within the low density area when it cannot be
avoided. No additional piping is allowed.
c. DISPERSED FLOW. The low density area has maximized dispersed flow of stormwater
runoff through vegetated areas and minimized the channelization of flow.
d. VEGETATED CONVEYANCES. Stormwater runoff that could not be released as dispersed
flow may be transported by vegetated conveyances with minimum side slopes of 3:1 (H:V)
designed to not erode during the peak flow from the 10-year storm event as defined in the
stormwater rules and approved by the Division.
4. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause erosion
downslope of the discharge point.
5. VEGETATED SETBACKS. A 50-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.
a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback
except as shown on the approved plans.
b. RELEASE OF STORMWATER NOT TREATED IN A STORMWATER CONTROL
MEASURE (SCM). Stormwater that is not treated in an SCM, such as in the low density
area (including roof drains), must be released at the edge of the vegetated setback and
allowed to flow through the setback as dispersed flow.
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 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.
d. DEEDS. The permittee shall incorporate specific restrictions and conditions into a facility
management plan or another legal instrument in lieu of deed restrictions and protective
covenants.
