4570 LONG BEACH ROAD
Oak Island, NC
Brunswick County
June 23, 2006
DESIGN NARRATIVE
Existing Site
Darske, LLC is proposing the development of a 1 03 acre tract of land, in Brunswick County
The proposed project site is located at 4570 Long Beach Road (NC 133), just to the north of
North Hampton Drive The site is currently undeveloped
Figure 1 - USGS
The Brunswick County SCS Sod Survey indicates that the property's soil is Yaupon silty clay
loam (YaB) Yaupon silty clay loam is a poorly drained to moderately well drained clayey soil
Surface runoff is slow and permeability is slow Engineering Consulting Services, LTD

preformed a field geotechnical investigation of the sites There report indicates that the soils on
the site have an infiltration rate of 3 3 to 4 2 inches per hour at the tested depth of 8" inches
below grade and a seasonal high water table at a depth of 24 to 30 inches below grade A
copy of their report is included in this report No wetlands have been identified on the property
The property is located in a basin that drains to the Calf Gully Creek, within the Lumber River
Basin and is not classified
Proposed Improvements
The proposed development will consist of 4 retail/office units, paved access drives and
parking, the necessary utilities services will be provided from the existing infrastructure and a
stormwater management system will provide treatment and pre/post attenuation The site will
be accessed from Long Beach Road A total of 40 parking spaces are provided to serve the
development The proposed impervious areas will are made up of 10,000 sq ft of buildings,
22,754 sq ft of asphalt and 1,850 sq ft of concrete paved areas, making the total built upon
area 33,306 sq ft , 77 1% of the 1 03 acre total property area
NCDENR requires that a BMP be provided to remove stormwater pollutants (treatment) from
the first 1" runoff In order to meet the treatment and attenuation requirement, the project's
stormwater runoff will be captured in infiltration trenches The trench bottom will be a minimum
of 2' above the seasonal high water table A bypass overflow structure is provided to discharge
excess stormwater The infiltration trenches will draw down in 2 to 5 days

Iv. UNDERGROUND INFILTRATION TRENCH OPERATION AND MAINTENANCE AGREEMENT
1 After every runofproducmg rainfall event and at least monthly inspect the bypass/overflow structure for
blockage and deterioration and 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 and blockages as needed to maintain system
performance
3 Remove accumulated sediment annually or when depth is reduced to 75% of the original design depth Restore
depth to 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.
4 The water level in any monitoring wells will be recorded after a l-inch rainfall event and at least once a month
Chronic high water table elevations (within 1 foot of the bottom of the system for a period of three months) shall
be reported to DWQ immediately
5 If DWQ determines that the system is failing, the system will immediately be repaired or replaced 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 constricted
5 Remove accumulated sediment from the mfiltration system annually or when depth m the 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
stockpilmg near a stormwater treatment device or stream, etc.)
A benchmark shall be established in the infiltration system. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken The measunng device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate mto accumulated sediments
When the depth at the benchmark reads 2.5" the accumulated sediment shale be removed
from the system.

and detail is shown on plans
u. A benchmark for checking sediment accumulation is provided
IV. UNDERGROUND INFILTRATION TRENCH OPERATION AND MAINTENANCE AGREEMENT
1 After every runoff producing rainfall event and at least monthly inspect the bypass/overflow structure for
blockage and deterioration and 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 and blockages as needed to maintain system
performance
3 Remove accumulated sediment annually or when depth is reduced to 75% of the original design depth. Restore
depth to 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
4 The water level in any monitoring wells will be recorded after a l -inch rainfall event and at least once a month
Chronic high water table elevations (within 1 foot of the bottom of the system for a period of three months) shall
be reported to DWQ immediately
5 if DWQ determines that the system is failing, the system will immediately be repaired or replaced 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
5 Remove accumulated sediment from the infiltration system annually or when depth in the umt 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 (Le
stockpiling near a storinwater treatment device or shvam, etc ).
A benchmark shall be established in the infiltration system. The benchmark will document the onginal
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 depth at the benchmark reads 2.5" , the accumulated sediment shall be removed
from the system.

4570 LONG BEACH ROAD
Oak island, NC
Brunswick County
June 23, 2006
DESIGN NARRATIVE
Existing Site
Darske, LLC is proposing the development of a 1 03 acre tract of land, in Brunswick County
The proposed project site is located at 4570 Long Beach Road (NC 133), just to the north of
North Hampton Drive The site is currently undeveloped
Figure 1 - USGS
The Brunswick County SCS Soil Survey indicates that the property's sal is Yaupon silty clay
loam (YaB) Yaupon silty clay loam is a poorly drained to moderately well drained clayey soil
Surface runoff is slow and permeability is slow Engineering Consulting Services, LTD

preformed a field geotechnical investigation of the sites There report indicates that the soils on
the site have an infiltration rate of 3 3 to 4 2 inches per hour at the tested depth of 8" inches
below grade and a seasonal high water table at a depth of 24 to 30 inches below grade A
copy of their report is included in this report No wetlands have been identified on the property
The property is located in a basin that drains to the Calf Gully Creek, within the Lumber River
Basin and is not classified
Proposed Improvements
The proposed development will consist of 4 retail/office units, paved access drives and
parking, the necessary utilities services will be provided from the existing infrastructure and a
stormwater management system will provide treatment and pre/post attenuation The site will
be accessed from Long Beach Road A total of 40 parking spaces are provided to serve the
development The proposed impervious areas will are made up of 10,000 sq ft of buildings,
22,754 sq ft of asphalt and 1,850 sq ft of concrete paved areas, making the total built upon
area 33,306 sq ft , 77 1 % of the 1 03 acre total property area
NCDENR requires that a BMP be provided to remove stormwater pollutants (treatment) from
the first 1" runoff In order to meet the treatment and attenuation requirement, the project's
stormwater runoff will be captured in infiltration trenches The trench bottom will be a minimum
of 2' above the seasonal high water table A bypass overflow structure is provided to discharge
excess stormwater The infiltration trenches will draw down in 2 to 5 days
