management system without submitting a revision to the permit and receiving
approval from the Division.
2. The permittee is responsible for verifying that the proposed built -upon area for
the entire lot, including driveways and sidewalks, does not exceed the allowable
built -upon area. Once the lot transfer is complete, the built -upon area may not be
revised without approval from the Division of Water Quality, and responsibility for
meeting the built -upon area limit is transferred to the individual property owner.
3. The Director may notify the permittee when the permitted site does not meet one
or more of the minimum requirements of the permit. Within the time frame
specified in the notice, the permittee shall submit a written time schedule to the
Director for modifying the site to meet minimum requirements. The permittee
shall provide copies of revised plans and certification in writing to the Director

IV. • INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly, inspect the infiltration system for erosion,
trash accumulation, grass cover, and general condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved
design specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored
to the original design depth without over -excavating. Over excavating may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as designed.
Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner
That will adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream,
etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used
to determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads 0.75 feet in the pretreatment unit, the sediment shall be removed
from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

o. Flow distribution mechanism within basin is provided.
fiDr— p. A benchmark is provided to determine the sediment accumulation in the pretreatment
device.
q. Runoff in excess of design volume bypasses off-line systems (bypass detail provided).
�-- r . System is. designed to draw down the design storage volume to the proposed bottom
elevation under seasonal high water conditions within five days. A soils report and all
pertinent draw -down calculations are attached.
s. Plans ensure that the installed system sill meet design specifications (constructed or
restored) upon initial operation once the project is complete and the entire drainage area
is stabilized.

IV. • INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly, inspect the infiltration system for erosion,
trash accumulation, grass cover, and general condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved
design specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored
to the original design depth without over -excavating. Over excavating may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as designed.
Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner
That will adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream,
etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used
to determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads 0.75 feet in the pretreatment unit, the sediment shall be removed
from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

In accordance with Title 15 NCAC 21-1.1000, the Coastal Stormwater Management Regulations, deed
restrictions and protective covenants are required for High Density Residential Subdivisions where
lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility.
Deed restrictions and protective covenants are necessary to ensure that the development maintains a
built -upon area consistent with the design criteria used to size the stormwater control facility.
I, Patrick Bradley Southerland , acknowledge, affirm and agree by my signature below, that I
will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number SW8 as issued by the Division of Water Quality
under NCAC 2H.1000,
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming
under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express
written consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Water Quality.
6. The maximum allowable built -upon area per lot is 4.000 square feet. This allotted amount
includes any built -upon area constructed within the lot property boundaries, and that portion of
the right-of-way between the front lot line and the edge of the pavement. Built upon area
includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina
and parking areas, but does not include raised, open wood decking, or the water surface of
swimming pools.
7. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street,
grading the lot to drain toward the street, or grading perimeter swa/es to collect the lot runoff
and directing them into a component of the stormwater collection system. Lots that will naturally
drain into the system are not required to provide these additional measures.

RFTS Job No. 241-07
Dear Mr. Cazier:
RFTS is pleased to provide testing services during the de . sign phase of the proposed
Middle Sound. residential development located off Middle Sound' Loop Road in
Wilmington, North Carolina.
DESCRIPTION OF ACTIVITIES AND FINDINGS
As requested; our staff visited the site on June 21, 200.7, to perform infiltration testing,
and, estimate the seasonal high watertable it one. location identified by you. The purpose�
of this testing was -to provide soil parameters f6r stonnwater infiltration design.
Seasonal: Hijh Watertable Estimate
A. hand: auger boring, MW advanced at, one location to a depth: of approximately 9 feet,
belo*-the existing ground' surface. within -an area proposed., by the civil designer- for. an
infiltration basin. The encountered soils were. logged and visually classified by depth. and
a Munsell Soil Color Chart was used to determine -the hue, value, and chroma, of the
visually distinct soil layers. Our soil logs are presented in Table 1.
Soils encountered. in our boring. consist of interbedded clean I fine to medium sands with
'one distinct, zone of soil cementation in the upp . er 22 to,31 inches below the existing
-ground surface. This cemented layer- was underlain by interbedded layers of sands with
clay, clayey sands,. and clay with sand. Comparison. of the soils to the Munsell Chart
suggests 'the presence of. a. limited zone of aerated soils above the cemented zone,,
indicatbie of perchcd seasonal water at, 22. inches below the existing ground surface.
Measurements made 1 - hour after augerin9 indicate a depth to standing. water in the
borehole of 102, inches below the. existing ground surface.'

local -department of environment, and natural resources authorities: The results of our
permeameter testing are 'presented in Table.2.
RECOMMENDATIONS
Based on the results of our field testing and soil classifications -at -the test location, it is
our opinion that in order to achieve the -steady state flow rates. obtained during our testing,
the areas of infiltration galleries or other infiltration structures should be designed to.
introduce ston ' nwater at -the approximate ground.surface elevation at which our testing
was performed. For. purposes of sizing the structures we recommend an ultimate
application rate of 3.7 inches per. hour. These recommendations
s should be reviewed by
a

Summary/Comments:

All proposed infiltration areas and existing, active utility lines located within the proposed basin/trench
must be marked and flagged. If these areas are not flagged, the Soils Scientist reserves the right to
decline to do the investigation. If the proposed infiltration system will be located in an area of existing
pavement and there is no open area nearby, equipment capable of breaking through the impervious
layer must be provided. The soils investigation does not take the place of a soils report prepared by
an appropriate professional, The Soils Scientist will only verify the soil conditions that are reported in
the Soils Report, and make a determination as to the suitability of the site to meet the infiltration
design requirements under NCAC 2H,1000, and assumes no liability should the system fail.
