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.
BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 92,028
square feet. The runoff from all BUA within the permitted drainage areas of this project must be
directed into the permitted SCMs. The BUA requirements and allocations for this project are as
follows:
a. SCM BUA LIMITS, The SCMs labeled DA 1, DA 2, DA 3, DA 4, DA 5, DA 6, and DA 7 have
been designed using the runoff treatment method to handle the runoff from 40,556, 6,637,
10,175. 8,186, 7,872, 11,988, and 6,614 square feet of BUA, respectively, within the
delineated drainage areas. This permit does not provide any allocation of BUA for future
development within the delineated drainage areas.
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. 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 SCMs are permitted based on the design criteria presented in the
sealed, signed and dated supplement and as shown in the approved plans and
specifications. These SCMs must be provided and maintained at the design condition.
b. PRETREATMENT. The following pretreatment device has been provided to prevent
clogging in the infiltraion SCMs: sumps in catch basins.
PERMEABLE PAVEMENT. The following considerations pertain to the proposed infiltrating
permeable pavement:
i. Except for the incidental, unavoidable runoff from the stable vegetated areas shown
on the approved plans, runoff from adjacent pervious areas shall be prevented from
reaching the permeable pavement.
ii. It is recommended that during the installation of the permeable pavement, care is
taken to avoid compaction of the underlying subgrade soils. To confirm compaction
has not occurred, it is recommended that a direct measurement of the soil's
infiltration rate be conducted after excavation and before the aggregate is placed.
If the infiltration rate has diminished, it is recommended to scarify, rip, or trench the
subgrade to restore the infiltration rate.
iii. After installation, the permeable pavement shall be protected from sediment
deposition until the site is completed and stabilized.
iv. Concentrations of oils, grease, heavy metals, and toxic chemicals shall not be
stored or handled where they may enter the permeable pavement.
V. At no time shall the approved permeable pavement be paved over or repaired with
any type of conventional paving material.
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 AN SCM. Stormwater that is not treated
in an SCM 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, 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.

Overall, the both DA and BUA to the SCMs are increasing within the Original project boundary. Site
layout changes include revising the alignment of Nutt Street (previously Old Front Street) and the
grading to allow the reduction of permeable pavement along Nutt Street to avoid it extending beyond
the parking spaces. These changes result in the following impacts to the SCMs:
DA I / infiltration trench A - increasing both the drainage area (DA) and built -upon area (BUA) to the
SCM. The trench length in increasing to handle the additional runoff
DA 5 / permeable pavement East A - decreasing both the DA and BUA to the SCM. The permeable

Infiltration System Maintenance Requirements
Important maintenance procedures'.
- The drainage area will be carefully managed to reduce The sediment load to The infiltration basin.
Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until
the plants become established (commonly six weeks).
No portion of the infiltration basin will be fertilized after the initial fertilization that is required to establish the
vegetation.
- The vegetation in and around the basin will be maintained at a height of approximately six inches.
After the infiltration basin is established, it shall be inspected once a quarter and within 24 hours after every storm event
greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance shall be kept in a known
set location and shall be available upon request.
