Revised Plans Dated 3/23/87
Onslow County
The applicant is proposing to build a condominium complex with
180 units. The project is located adjacent to the Atlantic
Ocean, and further than 575 feet from any waters classified SA.
Due to the proximity to SA waters the project is not required to
develop a stormwater management plan in accordance with DEM's
stormwater regulations. The project is located adjacent to
Highway 210 whose roadside ditches are connected either directly
or indirectly to SA waters.
The project has been reviewed to determine impacts to water
quality. The following comments are offered:
1. That a 401 Certification is not required.
2. In order to protect water quality, there should be no
discharge of stormwater runoff to the roadside ditches of
Highway 210 from the proposed development in response to an
event less severe than the 2-year 24-hour storm event, with
the exception of the runoff generated from the connecting
drive approaches.
This office has no objection to the project provided the above
comments are conditions of the CAMA permit.

9. Narrative Description
The applicant's property consists of an approximately 10.6 acre
tract of land located approximately 1.2 miles southwest of the
West Onslow Beach Bridge in Onslow County. The site is bordered
on the north by NC highway 210 and on the south by the Atlantic
Ocean.
The site can be characterized as having a fairly large and
distinct primary dune system along the approximately 1000 li. ft.
of ocean frontage which ranges in elevations from 10' to 28'
above mean sea level by approximately 100' in width. This
primary dune system is distinctly separated from the remainder of
the site by the old road bed alignment of N.C. Highway 210. The
primary dune system is vegetated primarily with american beach
grass, sea oats, bitter panicum and spartina patens. Recent
storm erosion has severely eroded the oceanward toe of this dune
system by distances ranging from 15-201, leaving for the most
part, a vertical dune cliff. The applicant recently received a
minor CAMA permit from Onslow County to perform beach bulldozing
of which approximately 700 li. ft. of the oceanward toe has been
re-established.
North of the old road bed the site consists of a series of
smaller dune ridges and troughs with the exception of one dune
which reaches above 17' mean sea level. For this most part this
area is vegetated with beach grasses and maritime shrub thickets
(consisting of red cedar, yaupon and live oak). Approximately
one and one-half years ago the applicant erected a sales model
unit on the site with associated drive and parking area.
The applicant is proposing to develop this site into a 180 unit
high-rise condominium complex with an associated restaurant
facility. The plans call for the grading and disturbance of
approximately 4.5 acres of land area for the preparation of
building sites, parking areas, stormwater management control
structures, swimming pools, etc. The residential structures will
be built out of steel reinforced concrete and will be constructed
on a combination of pilings and reinforced slab. Each building
will range from 5-7 stories with the top-most roof reaching 89'
above mean sea level. The first habitable floor elevation will
be at 18' above mean sea level. The plans included with the
application indicate that the foot print of all buildings will be
constructed at least 120' away from the vegetation line. Seaward
of the large structure setback asphalt parking areas, decks,
retaining walls, walkways and stormwater control basins are
proposed.
The applicant has included with his application a stormwater
management plan and an erosion control plan which shows the
proposed drainage pattern for the site. A part of the erosion
plan calls for the retention of stormwater within a number of
basin areas, some of which are proposed to be constructed in the
landward toe of the primary dune. Retaining walls are proposed
to be constructed in this dune area to facilitate basin
construction. Overflow stormwater on the north side of the tract
is proposed to be discharged into the ROW ditches of N.C. Hwy 12.
This ditch system ultimately discharges into White Wood Creek
(which is located on the north side of Hwy 210). This
lake/impoundment area is not listed by DEM as being classified
waters of the state. The DEM has also made a preliminary
determination that this project will not be subject to any
stormwater regulations due to its location away from SA waters.
10. Anticipated Impacts
The project as proposed will result in the clearing and
landscaping of approximately 4.5 acres of oceanfront beach
property which is vegetated with beach grasses and maritime
thicket vegetation. Secondary dune systems will be graded and
sloped to pre-determined elevations for stormwater control.
Additionally, a portion of the primary dune system is proposed to
be bulkheaded and excavated in order to provide stormwater
retention basins.
The condominium buildings are proposed to be placed on pilings
and will be also supported by concrete pads which will be built
on grade. Parking areas will also be provided underneath the
units with the first habitable floor elevation being proposed at
18' above mean sea level. Sewage will be collected and pumped to
a mainland site which is operated by North Topsail Water and
Sewer Inc. Potable water will be supplied by Onslow County.
Plans included with the application show that the residential
structures are proposed to be constructed at least 120' away from
the first line of vegetation. Recent storm erosion has, however,
removed approximately 15-20' of the dune system (and vegetation
line), making the corner units of the buildings inconsistent with
the mandatory setback of 1201. The beach bulldozing which has
recently occurred cannot be used to reestablish the vegetation
line to pre-storm locations.
The majority of stormwater runoff is proposed to be handled
onsite with overflow being ultimately discharged into White Head
Lake, an unclassified water by DEM. Preliminary indicators from
DEM indicate that this project will not be required to develop a
stormwater management plan under their rules.

Whitewood Lake

Onslow County
Dear Mr. Mercer:
On April 21, 1986, you submitted a written request to this office concerning a
determination of surface water classification for Whitewood Lake. As. indicated,
you anticipate that the proposed 10.62 acre Loggerhead Condominium Development
may have some stormwater overflow into the drainge area to the lake.
On June. 4, 1986, Mr. Mike Williams of my staff collected water quality information
in the vicinity of Whitewood Lake. Results of the study indicate that the waters
in and around the lake are brackish. Salinity values ranged from 11 to 13 parts
per thousand. Conductivity values ranged from 18,000 umho to 23,000 umho. Sampling
was performed at the east and west ends of the lake. Based on sampling results,
it is expected that some periodic interconnection to saline waters may exist. No
shellfish were found, nor did a typical shellfish habitat exist in the area surveyed.
According to the stream classification schedule, Whitewood Lake is not listed as
being classified waters of the State. Rogers Bay, which is located approximately
3,000 feet west of the Loggerhead Project, is classified SA waters.
Based on Mr. Williams' investigation, we have determined that.adequate protection
of the nearby SA waters will be afforded if the Loggerhead. Development is designed
to contain the runoff from the site in the event of a 2-year 24-hour storm; alterna-
tively, if the amount of effective impervious surfaces is restricted to 30% or less.

DESCRIPTION OF STRUCTURAL SYSTEM

The foundation system for Building `B' of the Loggerhead Resort is composed
of driven precast concrete piles ten (10) inches square and thirty five (35) to
forty (40) feet in length. The piles are to have a capacity of seventy (70)
tons in compression and thirty (30) tons in tension. Piles are to have a
minimum spacing center to center of 3.5 pile diameters and are located to
support the columns and shear walls composing the main body of the structure.
The main structural body of the building is comprised of cast-in-place concrete
columns, slabs, and shear walls. The columns are steel reinforced concrete in
several sizes depending upon load requirements. Slabs are steel reinforced
poured-in-place concrete with post tensioning cables (stressed when the concrete
reaches a compressive strength of 3000 psi) to minimize slab thickness. Shear
walls are to be 10 inch steel reinforced cast-in-place concrete walls located around
the vertical circulation shafts, at the building center, and at the building ends.
A two (2) inch continuous mechanical expansion joint occurs at the center of
the building where the wings intersect.
The remaining structure is comprised of small amounts of steel framing which
occur over the access corridor on the seventh floor and as structural support
for the parapet roofing. This structure is composed of small `W' sections and
tubular steel (galvanized) with field welded connections.

S&ME Job No. WIL-988
Dear Mr. Mercer:
Soil & Material Engineers, Inc. personnel have recently completed
the authorized site investigation at the proposed Nasekos/Mercer development to
be constructed in Stump Sound Township, Onslow County, North Carolina. The
scope of our investigation, as per your request, is as follows:
- To determine groundwater levels on site
- To classify the subsurface soils above the groundwater
level
- To determine the permeability of the soils above the
groundwater level
The results of our investigation are presented in the subsequent sections of
this letter.
Site Description
The proposed project site is located in Onslow County approximately
1.2 miles southwest of the West Onslow Beach Bridge. The site is a portion of
the J. T. and G. C. Jeffreys Tract and is bounded on the north by N. C. Highway
210 and on the south by the Atlantic Ocean.
The northern portion of the site is covered with small trees and
underbrush, whereas the remaining portion of the site is sparsely covered with
grass and underbrush. Sand dunes are located along the southern portion of the
site where existing ground surface elevations range from approximately +10 to
+28 Mean Sea Level (MSL). The old road bed for abandoned N. C. Highway 210
traverses the site along the northern toe of the barrier sand dunes. A few
sand dunes are located across the central portion of the site with peak
elevations ranging from about +10 to +17 MSL. Typical ground surface
elevations across the northern and central portion of the site vary from
approximately +5 to +10 MSL.

Subsurface Conditions
The subsurface conditions at the site were determined at six
locations across the site by excavating the in-place soils with a hand auger.
As each test hole was excavated, our personnel visually classified the
subsurface soils and measured the depth to the watertable. As shown in Table 1,
the near subsurface soils consist entirely of clean sands. At most locations,
these sands were noted to contain shell fragments.
During our field investigation, the depth of groundwater was noted
to range from 6.7 to 8.7 feet below the existing ground surface. Because the
near surface soils consist of relatively clean sands and because of the
proximity of the Atlantic Ocean, the site groundwater level will be influenced
by changes in tidal and rainfall conditions. The groundwater depths obtained
during this study are presented in Table 1 with approximate groundwater
elevations calculated using a topo prepared in October 1985 by Cowan and Jones,
P. A. If it is necessary to define the effects of tidal and seasonal
fluctuations on the site groundwater level, we recommend that monitoring wells
be installed and periodic measurements of the groundwater depth be taken.
Laboratory and Field Testing
Laboratory testing was performed on representative soil samples
obtained during our field investigation in order to determine the grain size
characterisics of the sands for the purpose of estimating in-place permeability
values. In addition to our laboratory testing, our personnel conducted field
percolation tests at six locations across the site to determine the
permeability characteristics of the in-place soils. The results of these tests
are presented in Table 2. The results of our field and laboratory testing and
our past experience with similar soils indicate that the in-place clean sands
have permeability values ranging from approximately 1 x 10-2 to 1 x 10-3
centimeter per second.

FROM:
SUBJECT: Application for CAMA Permit
Nasekos/Mercer Development Assoc.
Onslow County
The Subject application has been reviewed for water
quality impacts and the following comments are offered:
a. The proposed project will not require a 401 Water
Quality Certification.
b. This project is more than 575 feet from SA waters
and thus is not subject to the stormwater
regulations. However, the project is located
adjacent to Highway 210 where the roadside ditches
are connected either directly or indirectly to SA
water. Therefore in order to assure protection of
SA waters from potential stormwater runoff, there
should be no discharge of stormwater runoff
allowed to the roadside ditches of Highway 210
from the proposed development in response to an
event less severe than the 2-year, 24-hour storm
event, with the exception of the runoff generated
from the connecting driveway approaches to the
highway.

Ocean - Onslow Count
a

9. Narrative Description
The applicant's property consists of an approximately 10.6 acre
tract of land located approximately 1.2 miles southwest of the
West Onslow Beach Bridge in Onslow County. The site is bordered
on the north by NC highway 210 and on the south by the Atlantic
Ocean.
The site can be characterized as having a fairly large and
distinct primary dune system along the approximately 1000 li. ft.
of ocean frontage which ranges in elevations from 10' to 28'
above mean sea level by approximately 100' in width. This
primary dune system is distinctly separated from the remainder of
the site by the old road bed alignment of N.C. Highway 210. The
primary dune system is vegetated primarily with american beach
grass, sea oats, bitter panicum and spartina patens. Recent
storm erosion has severely eroded the oceanward toe of this dune
system by distances ranging from 15-201, leaving for the most
part, a vertical dune cliff. The applicant recently received a
minor CAMA permit from Onslow County to perform beach bulldozing
of which approximately 700 li. ft. of the oceanward toe has been
re-established.
North of the old road bed the site consists of a series of
smaller dune ridges and troughs with the exception of one dune
which reaches above 17' mean sea level. For this most part this
area is vegetated with beach grasses and maritime shrub thickets
(consisting of red cedar, yaupon and live oak). Approximately
one and one-half years ago the applicant erected a sales model
unit on the site with associated drive and parking area.
The applicant is proposing to develop this site into a 180 unit
high-rise condominium complex with an associated restaurant
facility. The plans call for the grading and disturbance of
approximately 4.5 acres of land area for the preparation of
building sites, parking areas, stormwater management control
structures, swimming pools, etc. The residential structures will
be built out of steel reinforced concrete and will be constructed
on a combination of pilings and reinforced slab. Each building
will range from 5-7 stories with the top-most roof reaching 89'
above mean sea level. The first habitable floor elevation will
be at 18' above mean sea level. The plans included with the
application indicate that the foot print of all buildings will be
constructed at least 120' away from the vegetation line. Seaward
of the large structure setback asphalt parking areas, decks,
retaining walls, walkways and stormwater control basins are
proposed.
The applicant has included with his application a stormwater
management plan and an erosion control plan which shows the
proposed drainage pattern for the site. A part of the erosion
plan calls for the retention of stormwater within a number of
basin areas, some of which are proposed to be constructed in the
landward toe of the primary dune. Retaining walls are proposed
to be constructed in this dune area to facilitate basin
construction. Overflow stormwater on the north side of the tract
is proposed to be discharged into the ROW ditches of N.C. Hwy 12.
This ditch system ultimately discharges into White Wood Creek
(which is located on the north side of Hwy 210). This
lake/impoundment area is not listed by DEM as being classified
waters of the state. The DEM has also made a preliminary
determination that this project will not be subject to any
stormwater regulations due to its location away from SA waters.
10. Anticipated Impacts
The project as proposed will result in the clearing and
landscaping of approximately 4.5 acres of oceanfront beach
property which is vegetated with beach grasses and maritime
thicket vegetation. Secondary dune systems will be graded and
sloped to pre-determined elevations for stormwater control.
Additionally, a portion of the primary dune system is proposed to
be bulkheaded and excavated in order to provide stormwater
retention basins.
The condominium buildings are proposed to be placed on pilings
and will be also supported by concrete pads which will be built
on grade. Parking areas will also be provided underneath the
units with the first habitable floor elevation being proposed at
18' above mean sea level. Sewage will be collected and pumped to
a mainland site which is operated by North Topsail Water and
Sewer Inc. Potable water will be supplied by Onslow County.
Plans included with the application show that the residential
structures are proposed to be constructed at least 120' away from
the first line of vegetation. Recent storm erosion has, however,
removed approximately 15-20' of the dune system (and vegetation
line), making the corner units of the buildings inconsistent with
the mandatory setback of 1201. The beach bulldozing which has
recently occurred cannot be used to reestablish the vegetation
line to pre-storm locations.
The majority of stormwater runoff is proposed to be handled
onsite with overflow being ultimately discharged into White Head
Lake, an unclassified water by DEM. Preliminary indicators from
DEM indicate that this project will not be required to develop a
stormwater management plan under their rules.

Request for a,
Dated 4/21/-W-
Whitewood Lake
West Onslow Beach
Onslow County
On April 21, 1986, you submitted a written request to this office concerning a
determination of surface water classification for Whitewood Lake. As indicated,
you anticipate that the proposed 10.62 acre Loggerhead Condominium Development
may have some stormwater overflow into the drainge area to the lake.
On June.4, 1986, Mr. Mike Williams,of my staff collected water quality information
in the vicinity of Whitewood Lake. Results of the study indicate that the waters
in and around the lake are brackish. Salinity values ranged from 11 to 13 parts
per thousand. Conductivity values ranged from 18,000 umho to 23,000 umho. Sampling
was performed at the east and west ends of the lake. Based on sampling results,
it is expected that some periodic interconnection to saline waters may exist. No
shellfish were found, nor did a typical shellfish habitat exist in the area surveyed.
According to the stream classification schedule, Whitewood Lake is not listed as
being classified waters of the State. Rogers Bay, which is located approximately
3,000 feet west of the Loggerhead Project, is classified SA waters.
Base& on Mr. Williams' investigation, we have determined that adequate protection
of the nearby SA waters will be afforded if the Loggerhead-Development is designed
to contain the runoff from the site in the event of a 2-year 24 hour storm; alterna-
tively, if the amount of effective impervious surfaces is restricted to 30% or less.

DESCRIPTION OF STRUCTURAL SYSTEM

The foundation system for Building `B' of the Loggerhead Resort is composed
of driven precast concrete piles ten (10) inches square and thirty five (35) to
forty (40) feet in length. The piles are to have a capacity of seventy (70)
tons in compression and thirty (30) tons in tension. Piles are to have a
minimum spacing center to center of 3.5 pile diameters and are located to
support the columns and shear walls composing the main body of the structure.
The main structural body of the building is comprised of cast-in-place concrete
columns, slabs, and shear walls. The columns are steel reinforced concrete in
several sizes depending upon load requirements. Slabs are steel reinforced
poured-in-place concrete with post tensioning cables (stressed when the concrete
reaches a compressive strength of 3000 psi) to minimize slab thickness. Shear
walls are to be 10 inch steel reinforced cast-in-place concrete walls located around
the vertical circulation shafts, at the building center, and at the building ends.
A two (2) inch continuous mechanical expansion joint occurs at the center of
the building where the wings intersect.
The remaining structure is comprised of small amounts of steel framing which
occur over the access corridor on the seventh floor and as structural support
for the parapet roofing. This structure is composed of small `W' sections and
tubular steel (galvanized) with field welded connections.

Attention: Mr. Dennis Mercer

Proposed Nasekos/Mercer Development
Stump Sound Township, Onslow County, North Carolina
S&ME Job No. WIL-988
Dear Mr. Mercer:
Soil 5 Material Engineers, Inc. personnel have recently completed
the authorized site investigation at the proposed Nasekos/Mercer development to
be constructed in Stump Sound Township, Onslow County, North Carolina. The
scope of our investigation, as per your request, is as follows:
- To determine groundwater levels on site
- To classify the subsurface soils above the groundwater
level
- To determine the permeability of the soils above the
groundwater level
The results of our investigation are presented in the subsequent sections of
this letter.
Site Description
The proposed project site is located in Onslow County approximately
1.2 miles southwest of the West Onslow Beach Bridge. The site is a portion of
the J. T. and G. C. Jeffreys Tract and is bounded on the north by N. C. Highway
210 and on the south by the Atlantic Ocean.
The northern portion of the site is covered with small trees and
underbrush, whereas the remaining portion of the site is sparsely covered with
grass and underbrush. Sand dunes are located along the southern portion of the
site where existing ground surface elevations range from approximately +10 to
+28 Mean Sea Level (MSL). The old road bed for abandoned N. C. Highway 210
traverses the site along the northern toe of the barrier sand dunes. A few
sand dunes are located across the central portion of the site with peak
elevations ranging from about +10 to +17 MSL. Typical ground surface
elevations across the northern and central portion of the site vary from
approximately +5 to +10 MSL.

Subsurface Conditions
The subsurface conditions at the site were determined at six
locations across the site by excavating the in-place soils with a hand auger.
As each test hole was excavated, our personnel visually classified the
subsurface soils and measured the depth to the watertable. As shown in Table 1,
the near subsurface soils consist entirely of clean sands. At most locations,
these sands were noted to contain shell fragments.
During our field investigation, the depth of groundwater was noted
to range from 6.7 to 8.7 feet below the existing ground surface. Because the
near surface soils consist of relatively clean sands and because of the
proximity of the Atlantic Ocean, the site groundwater level will be influenced
by changes in tidal and rainfall conditions. The groundwater depths obtained
during this study are presented in Table 1 with approximate groundwater
elevations calculated using a topo prepared in October 1985 by Cowan and Jones,
P. A. If it is necessary to define the effects of tidal and seasonal
fluctuations on the site groundwater level, we recommend that monitoring wells
be installed and periodic measurements of the groundwater depth be taken.
Laboratory and Field Testing
Laboratory testing was performed on representative soil samples
obtained during our field investigation in order to determine the grain size
characterisics of the sands for the purpose of estimating in-place. permeability
values. In addition to our laboratory testing, our personnel conducted field
percolation tests at six locations across the site to determine the
permeability characteristics of the in-place soils. The results of these tests
are presented in Table 2. The results of our field and laboratory testing and
our past experience with similar soils indicate that the in-place clean sands
have permeability values ranging from approximately 1 x 10-2 to 1 x 10-3
centimeter per second.
