TRACY DAVIS
The Division of Energy, Mineral, and Land Resources (DELMR), received a complete Stormwater
Management Permit Application for the subject project on August 5, 2016. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater Regulations
set forth in Title 15A Section NCAC 214.1000. We are forwarding Permit No. SW 1160801, dated August
11, 2016, for the construction, operation and maintenance of the subject project and the stormwater
system. This permit shall be effective from the date of issuance until August 11, 2024, or until rescinded
and shall be subject to the conditions and limitations as specified therein, and does not supersede any
other agency permit that may be required.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings
(OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes. Per
NCGS 143-215(e) the petition must be filed with the OAH within thirty (30) days of receipt of this
permit. You should contact the OAH with all questions regarding the filing fee (if a filing fee is required)
and/or the details of the filing process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or via
telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made
this permit shall be final and binding.
This project will be kept on file at the Asheville Regional Office. If you have any questions, or need
additional information concerning this matter, please contact Mike Randall at (919) 807-6374; or

This project requirements are to meet water quality per the NCDENR Design Manual and Detention per NCDOT
requirements. The project entails the construction of a 3,886 S.F. Bojangles Restaurant. Total Site area is 1.28 a.c. and
proposed BUA is 0.83 acres. A Sandfilter BMP is designed to handle the first I" of rainfall. Due to stormwater entering
the NCDOT Storm system the WQ Sandfilter is also used as a detention basin to route post developed Flows for the 1, 10
and 25 year Flows to pre -developed Flows.

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers In parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a
given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Alias 14 document for more information.

t Precipilation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at boar and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates
(for a gNen duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) Is 5 % . Estimates at upper bounds
are not checked against probable maxtrnum precipitation (PMP) estimates and may be higher than currently valid PMP values.

EXECUTIVE SUMMARY
This report presents the results of our geotechnical engineering services performed for the
proposed Bojangles restaurant to be located 3591 Boylston Highway in Mills River, Henderson
County, North Carolina. Our geotechnical engineering scope of work included the advancement
of nine (9) soil test borings to depths between 7 '/2 to 25 feet below existing site grades. This report
specifically addresses the recommendations for the proposed building and pavement areas.
Based on the information obtained from our subsurface exploration, the following geotechnical
considerations were identified:
o The borings encountered approximately 2'/z to 10 feet of undocumented fill. Below the fill,
borings encountered loose to medium dense silty sand/sandy silt to boring termination
depths ich ranged from 7'/2 to 25 feet below ground surface. Records are not available to
determine if the fill was placed in a controlled manner during grading.
o The proposed building addition may be supported on shallow foundation bearing on the
native residual soils, engineered fill extending to residual soils, or existing fill provided it is
assessed during construction and the risks associated with the fill as discussed herein are
acceptable to the owner. The shallow foundations may be designed with an allowable
bearing pressure of 2,500 pounds per square foot (psf).
o Groundwater was observed at depths of 6 to 22 feet in some borings for the short duration
that the borings were allowed to remain open. We do not anticipate groundwater will affect
construction activities based on our current understanding of the proposed development.
o Borings encountered high fines content and natural moisture in the upper materials and the
site is susceptible to disturbance during construction or in wet conditions. The subgrade
should be graded to provide positive drainage and it should be protected by keeping it dry
and preventing heavy vehicles in the footprint of the proposed construction
o In accordance with 2012 International Building Code (IBC), seismic site classification for
this site is D.
o The native soils typically appear suitable for use as general engineered fill; however, further
testing should be performed during construction to assess specific conditions at that time.
Close monitoring of the construction operations discussed herein will be critical in achieving the
design subgrade support. We therefore recommend that Terracon be retained to monitor this
portion of the work.

Existing Improvements
The site is currently developed as an Auto Store with associated

Current Ground Cover
Gravel, and manicured grass.
Existing topography
Relatively flat.
3.0 SUBSURFACE CONDITIONS
3.1 Site Geology
The project site is located within the Blue ridge Physiographic Province of North Carolina, an
area underlain by ancient igneous and metamorphic rocks. Residual soils in this area are the
product of in -place chemical weathering of rock. The typical residual soil profile consists of
clayey soils near the surface where soil weathering is more advanced, underlain by sandy silts
and silty sands that generally become harder with depth to the top of parent bedrock.
The boundary between soil and rock is not sharply defined due to variations in weathering and
the presence of soft rock. The transition zone is locally termed as "partially weathered rock."
Partially weathered rock is defined for engineering purposes as residual material that can be
drilled with soil boring methods, but exhibits standard penetration test (SPT) N-values
exceeding 100 blows per foot (bpf). Partially weathered rock occurs at irregular depths due to
variations in degree of weathering and variations in the material composition of the rock.

3.2 Typical Subsurface Profile
Based on the results of the SPT borings, subsurface conditions on the project site can be
generalized as follows:
Description
Approximate Depth to Bottom
of Stratum (feet)
Material Encountered
SPT N value
Stratum 1
3 to 10

6 to 14
medium stiff, fat clay
Residual — very stiff , sandy silt,
Stratum 2
7'/z to 25
and loose to medium dense
6 to 21
silty!
Specific conditions encountered at each boring location are indicated on the individual boring logs.
Stratification boundaries on the boring logs represent the approximate location of changes in soil
types; in -situ, the transition between materials may be gradual. Details for each of the borings can
be found on the boring logs included in Appendix A of this report.
3.3 Groundwater
The boreholes were observed while drilling and after completion for the presence and level of
groundwater. Groundwater was observed between 6 and 22 feet in some borings while drilling,
and for the short duration (4 hours or less) that the borings were allowed to remain open. Due to
the low permeability of the soils encountered in the borings, a relatively long time may be
necessary for a groundwater level to develop and stabilize in a borehole in these materials. Longer
observations in piezometers or observation wells sealed from the influence of surface water are
often required to define groundwater levels in materials of this type.
Groundwater level fluctuations occur due to seasonal variations in the amount of rainfall, runoff
and other factors not evident at the time the borings were performed. In addition, perched water
could develop in sand seams and layers overlying lower permeability clay soils following periods
of heavy or prolonged precipitation. Therefore, groundwater levels during construction or at
other times in the life of the structure may be higher or lower than the levels indicated on the
boring logs. The possibility of groundwater level fluctuations should be considered when
developing the design and construction plans for the project.

4.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION
4.1 Geotechnical Considerations
Borings for the proposed Bojangles' Building encountered undocumented fill material to depths of
3 to 10 feet below existing grade. Residual soils were encountered below the fill until the boring
termination depths.
Support of pavements, footings and floor slabs on or above the undocumented fill soils is
discussed in this report. However, even with the recommended construction testing services,
there is an inherent risk for the owner that compressible fill or unsuitable material within or
buried by the undocumented fill will not be discovered. This risk of unforeseen conditions
cannot be eliminated without completely removing the existing fill, but can be reduced by
performing additional testing and evaluation. Simple testing such as closely spaced hand auger
borings in the foundation excavations can be performed to further assess the undocumented fill.
However, there are several geotechnical recommendations which must be performed during the
construction of the building. These include the following:
o Perform proofrolling in the building footprint in accordance with section 4.2 of this report.
o Based on our visual observation of the soil samples we believe that the onsite soils will
be suitable for use as engineered fill; however, further testing is recommended prior to
use.
o Due to the presence of fines in conjunction with high natural moisture in the upper
materials, the site is susceptible to disturbance during construction or in wet conditions.
Subgrade should be protected by keeping it dry and preventing heavy vehicles in the
footprint of the proposed construction.
Geotechnical engineering recommendations for foundation systems and other earth connected
phases of the project are outlined below. The recommendations contained in this report are
based upon the results of data presented herein, engineering analyses, and our current
understanding of the proposed project.
EWE*- i17,"7
The following presents recommendations for site and subgrade preparation, excavation, and
placement of engineered fills on the project. The recommendations presented for design and
construction of earth supported elements including foundations, slabs and pavements are
contingent upon following the recommendations outlined in this section.

Bojangles Restaurant- James Goode Property ■ Mills River, North Carolina
July 1, 2016 ■ Terracon Project No. 86165078
Earthwork on the project should be observed and evaluated by Terracon. The evaluation of
earthwork should include observation and testing during placement of engineered fill, subgrade
preparation, foundation bearing soils, and other geotechnical conditions exposed during the
construction of the project.
4.2.1 Site Preparation
We anticipate construction will start by demolishing the existing building and stripping the grass.
This activity should be performed with minimal disturbance to the subgrade soils.
The near surface sandy silts encountered in the borings will be sensitive to disturbance from
construction activity and water seepage. If precipitation occurs prior to or during construction,
the near -surface silty soils could increase in moisture content and become more susceptible to
disturbance. Construction activity should be monitored, and should be curtailed if the
construction activity is causing subgrade disturbance.
Proofrolling should be performed with heavy rubber tired construction equipment such as a fully
loaded tandem -axle dump truck. A geotechnical engineer or his representative should observe
proofrolling to help locate unstable subgrade materials. Proofrolling should be performed after a
suitable period of dry weather to avoid degrading an otherwise acceptable subgrade and to
reduce the amount of undercutting/ remedial work required. Unstable materials located should
be stabilized as directed by the engineer based on conditions observed during construction.
Undercut and replacement and densification in place are typical remediation methods.
4.2.2 Material Types
Engineered fill should meet the following material property requirements:
Fill Type'
1 USCS Classification
Acceptable Location for Placement
Imported sandy
ML, CL or SM
silts/clays and silty
(LL<45)
All locations and elevations
sands

All locations and elevations
1. Controlled, compacted fill should consist of approved materials that are free of organic matter and
debris. Frozen material should not be used, and fill should not be placed on a frozen subgrade. A
sample of each material type should be submitted to the geotechnical engineer for evaluation.

Engineered fill materials should be placed in horizontal, loose lifts not exceeding 9 inches in
thickness and should be thoroughly compacted. Where light compaction equipment is used, as
is customary within a few feet of retaining walls and in utility trenches, the lift thickness may
need to be reduced to achieve the desired degree of compaction. Soils removed which will be
used as engineered fill should be protected to aid in preventing an increase in moisture content
due to rain.
4.2.4 Grading and Drainage
Effective drainage should be provided during construction and maintained throughout the life of
the development to reduce moisture gains in the subgrade materials. Surface water drainage
should be controlled to prevent undermining of fill slopes and structures during and after
construction.
Gutters and downspouts that drain water a minimum of 10 feet beyond the footprint of the
proposed structures are recommended. This can be accomplished through the use of splash -
blocks, downspout extensions, and flexible pipes that are designed to attach to the end of the
downspout. Flexible pipe should only be used if it is daylighted in such a manner that it gravity -
drains collected water. Splash -blocks should also be considered below hose bibs and water
spigots.
It is recommended that all exposed earth slopes be seeded to provide protection against
erosion as soon as possible after completion. Seeded slopes should be protected until the
vegetation is established.

4.2.5 Construction Considerations
Although the exposed subgrade is anticipated to be relatively stable upon initial exposure, unstable
subgrade conditions could develop during general construction operations, particularly if the soils
are exposed to weather, wetted and/or subjected to repetitive construction traffic. The use of light
construction equipment would aid in reducing subgrade disturbance. Should unstable subgrade
conditions develop, stabilization measures will need to be employed.
Upon completion of filling and grading, care should be taken to maintain the subgrade moisture
content prior to construction of floor slabs and pavements. Construction traffic over the
completed subgrade should be avoided to the extent practical. If the subgrade should become
frozen, desiccated, saturated, or disturbed, the affected material should be removed or these
materials should be scarified, moisture conditioned, and recompacted prior to floor slab and
pavement construction.
Temporary excavations will probably be required during grading operations. The grading
contractor, by his contract, is usually responsible for designing and constructing stable,
temporary excavations and should shore, slope or bench the sides of the excavations as
required, to maintain stability of both the excavation sides and bottom. All excavations should
comply with applicable local, state and federal safety regulations, including the current OSHA
Excavation and Trench Safety Standards.
The geotechnical engineer should be retained during the construction phase of the project to
observe earthwork and to perform necessary tests and observations during subgrade
preparation; proof -rolling; placement and compaction of controlled compacted fills; backfilling of
excavations into the completed subgrade, and just prior to construction of building floor slabs.
4.3 Foundations
In our opinion, the proposed building can be supported by a shallow foundation system bearing
on residual soils, engineered fill extending to residual soils, or existing fill if it is assessed during
construction and the risks associated with the fill as discussed herein are acceptable to the
owner. Design recommendations for shallow foundations for the proposed structures are
presented in the following paragraphs.

1. The recommended net allowable bearing pressure is the pressure in excess of the minimum
surrounding overburden pressure at the footing base elevation. Assumes any unsuitable fill or soft
soils, if encountered, will be undercut and replaced with engineered fill.
2. And to reduce the effects of seasonal moisture variations in the subgrade soils. For perimeter
footings and footings beneath unheated areas.
3. The foundation settlement will depend upon the variations within the subsurface soil profile, the
structural loading conditions, the embedment depth of the footings, the thickness of compacted fill,
and the quality of the earthwork operations.
The allowable foundation bearing pressures apply to dead loads plus design live load
conditions. The design bearing pressure may be increased by one-third when considering total
loads that include wind or seismic conditions. The weight of the foundation concrete below
grade may be neglected in dead load computations. Interior footings should bear a minimum of
12 inches below finished grade. Finished grade is the lowest adjacent grade for perimeter
footings and floor level for interior footings.
Foundations and masonry walls should be reinforced as necessary to reduce the potential for
distress caused by differential foundation movement. The use of joints at openings or other
discontinuities in masonry walls is recommended.
Foundation excavations should be observed and evaluated by the geotechnical engineer. If the
soil conditions encountered differ from those presented in this report, supplemental
recommendations will be required.
4.3.2 Construction Considerations
The base of all foundation excavations should be free of water and loose soil prior to placing
concrete. Concrete should be placed soon after excavating to reduce bearing soil disturbance.
Should the soils at bearing level become excessively dry, disturbed or saturated, or frozen, the
affected soil should be removed prior to placing concrete. We recommend using a lean concrete
mud -mat over the bearing soils if the excavations must remain open for an extended period of
time.

If unsuitable bearing soils are encountered in footing excavations, the excavations should be
extended deeper to suitable soils and the footings could bear directly on these soils at the lower
level or on lean concrete backfill placed in the excavations. The footings could also bear on
properly compacted backfill extending down to the suitable soils. Overexcavation for
compacted backfill placement below footings should extend laterally beyond all edges of the
footings at least 8 inches per foot of overexcavation depth below footing base elevation. The
overexcavation should then be backfilled up to the footing base elevation with well -graded
granular material placed in lifts of 9 inches or less in loose thickness and compacted to at least
95 percent of the material's maximum dry density (ASTM D 698). The overexcavation and
backfill procedure is illustrated in the following figures for lean concrete or granular backfill.

4.4 Seismic Considerations
Code Used Site Classification
2012 International Building Code (IBC) t D 2
1. In general accordance with the 2012 International Building Code, Table 1613.3.2.
2. The 2012 International Building Code (IBC) requires a site soil profile determination extending a
depth of 100 feet for seismic site classification. The current scope requested does not include the
required 100 foot soil profile determination. Borings for the building extended to a maximum depth
of approximately 25 feet and this seismic site class definition considers that medium dense silty
sands continues below the maximum depth of the subsurface exploration. Deeper exploration could
be performed to confirm the conditions below the current depth of exploration. Alternatively, a
geophysical exploration could be utilized in order to attempt to justify a higher seismic site class.

4.5 Floor Slab
4.5.1 Design Recommendations
DESCRIPTION I VALUE
Minimum 18 inches of approved on -site or imported soils placed
Floor slab support and compacted in accordance with section 4.2 Earthwork of this
Aggregate base course/capillary 4-inch compacted layer of free draining, granular subbase
break Z material
1. Floor slabs should be structurally independent of any building footings or walls to reduce the
possibility of floor slab cracking caused by differential movements between the slab and
foundation. Narrower, turned -down slab -on -grade foundations may be utilized at the approval of
the structural engineer. The slabs should be appropriately reinforced to support the proposed
loads.
2. We recommend subgrades be maintained at the proper moisture condition until floor slabs are
constructed. If the subgrade should become desiccated or saturated (wetted) prior to construction
of floor slabs, the affected material should be removed or the materials scarified, moisture
conditioned and recompacted. Upon completion of grading operations in the building areas, care
should be taken to maintain the recommended subgrade moisture content and density prior to
construction of the building floor slabs.
A subgrade prepared and tested as recommended in this report should provide adequate
support for lightly loaded floor slabs. Where appropriate, saw -cut control joints should be placed
in the slab to help control the location and extent of cracking. For additional recommendations
refer to the ACI Design Manual.
The use of a vapor retarder or barrier should be considered beneath concrete slabs on grade
that will be covered with wood, tile, carpet or other moisture sensitive or impervious coverings,
or when the slab will support equipment sensitive to moisture. When conditions warrant the use
of a vapor retarder, the slab designer and slab contractor should refer to ACI 302 and ACI 360
for procedures and cautions regarding the use and placement of a vapor retarder/barrier.
4.5.2 Construction Considerations
On most project sites, the site grading is generally accomplished early in the construction phase.
However as construction proceeds, the subgrade may be disturbed due to utility excavations,
construction traffic, desiccation, rainfall, etc. As a result, the floor slab subgrade may not be
suitable for placement of base rock and concrete and corrective action may be required.
We recommend the area underlying the floor slab be rough graded and then thoroughly
proofrolled with a loaded tandem axle dump truck prior to final grading and placement of base
rock. Particular attention should be paid to high traffic areas that were rutted and disturbed earlier
and to areas where backfilled trenches are located. Areas where unsuitable conditions are

located should be repaired by removing and replacing the affected material with properly
compacted fill. All floor slab subgrade areas should be moisture conditioned and properly
compacted to the recommendations in this report immediately prior to placement of the base rock
and concrete.
4.6 Pavements
4.6.1 Subgrade Preparation
On most project sites, the site grading is accomplished relatively early in the construction phase.
However, as construction proceeds, excavations are made into these areas, rainfall and surface
water saturates some areas, heavy traffic from concrete trucks and other delivery vehicles
disturbs the subgrade and many surface irregularities are filled in with loose soils to improve
trafficability temporarily. As a result, the pavement subgrades, prepared early in the project
should be carefully evaluated as the time for pavement construction approaches.
We recommend the moisture content and density of the top 12 inches of the subgrade be
evaluated and the pavement subgrades be proofrolled within two days prior to commencement of
actual paving operations. Areas not in compliance with the required ranges of moisture or density
should be moisture conditioned and recompacted. Particular attention should be paid to high
traffic areas that were rutted and disturbed earlier and to areas where backfilled trenches are
located. Areas where unsuitable conditions are located should be repaired by removing and
replacing the materials with properly compacted fills. If a significant precipitation event occurs
after the evaluation or if the surface becomes disturbed, the subgrade should be reviewed by
qualified personnel immediately prior to paving. The subgrade should be in its finished form at the
time of the final review.
4.6.2 Design Considerations
Traffic patterns and anticipated loading conditions were not available at the time that this report
was prepared. However, we anticipate that traffic loads will be produced primarily by automobile
traffic and occasional delivery and trash removal trucks. The thickness of pavements subjected to
heavy truck traffic should be determined using expected traffic volumes, vehicle types, and vehicle
loads and should be in accordance with local, city or county ordinances.
Pavement thickness can be determined using AASHTO, Asphalt Institute and/or other methods if
specific wheel loads, axle configurations, frequencies, and desired pavement life are provided.
Pavement performance is affected by its environmental conditions. The civil engineer should
consider the following recommendations in the design and layout of pavements:
o Final grade adjacent to parking lots and drives should slope down from pavement edges at
a minimum 2%;
o The subgrade and the pavement surface should have a minimum '/ inch per foot slope to
promote effective surface drainage;

■ Pavement drainage should be installed in surrounding areas anticipated for frequent wetting;
■ Joint sealant should be installed immediately;
■ To reduce moisture migration to subgrade soils, all landscaped areas in or adjacent to
pavements should be sealed;
■ Compacted, low permeability backfill should be placed against the exterior side of curb and
gutter; and,
■ Curb, gutter and/or sidewalk should be placed directly on low permeability subgrade soils
rather than on unbound granular base course materials.

We recommend a portland cement concrete (PCC) pavement be utilized in entrance and exit
sections, dumpster pads, or other areas where extensive wheel maneuvering are expected.
Adequate reinforcement and number of longitudinal and transverse control joints should be
placed in the rigid pavement in accordance with ACI requirements. The joints should be sealed
as soon as possible (in accordance with sealant manufacturer's instructions) to minimize
infiltration of water into the soil.
4.6.4 Pavement Drainage
Pavements should be sloped to provide rapid drainage of surface water. Water allowed to pond
on or adjacent to the pavements could saturate the subgrade and contribute to premature
pavement deterioration. In addition, the pavement subgrade should be graded to provide positive
drainage within the granular base section.
We recommend drainage be included at the bottom of the Aggregate Base Course (ABC) layer
at the storm structures to aid in removing water that may enter this layer. Drainage could consist
of small diameter weep holes installed around the perimeter of the storm structures. The weep
holes should be installed at the elevation of the ABC and soil interface. The weep holes should
be covered with No. 57 stone which is encompassed in Mirafi 140 NL or approved equivalent
which will aid in reducing the amount of fines entering the storm system.
4.6.5 Pavement Maintenance
The pavement sections provided in this report represent minimum recommended thicknesses
and, as such, periodic maintenance should be anticipated. Preventive maintenance should be
planned and provided for through an on -going pavement management program to slow the rate of
pavement deterioration, and to preserve the pavement investment. Preventive maintenance
consists of both localized maintenance (e.g., crack and joint sealing and patching) and global
maintenance (e.g., surface sealing). Prior to implementing any maintenance, additional
engineering observation is recommended to determine the type and extent of preventive
maintenance. Even with periodic maintenance, some movements and related cracking may still
occur and repairs may be required.

Terracon should be retained to review the final design plans and specifications so comments
can be made regarding interpretation and implementation of our geotechnical recommendations
in the design and specifications. Terracon also should be retained to provide observation and

Bojangles Restaurant- James Goode Property ■ Mills River, North Carolina
July 1, 2016 ■ Terracon Project No. 86165078
Field Exploration Description
The subsurface exploration consisted of drilling and sampling 7 SPT borings (B-1 through B-9)
at the site to depths ranging from about 7 '/2 to 25 feet below existing grade. All borings were
located in the field by a Terracon engineer based on the proposed structure locations provided
by Client. The borings were laid out in the field using GPS coordinates obtained by overlaying
the site map on Google Earth TM software. The boring depths were measured from the existing
ground surface at the time of our field activities. The locations of the borings should be
considered accurate only to the degree implied by the means and methods used to define them.
The borings were drilled using a truck -mounted rotary drill rig using continuous flight hollow -stem
augers to advance the boreholes. Samples of the soil encountered in the borings were obtained
using the split -barrel sampling procedures. In the split -barrel sampling procedure, the number of
blows required to advance a standard 2-inch O.D. split -barrel sampler the last 12 inches of the
typical total 18-inch penetration by means of a 140-pound conventional safety hammer with a free
fall of 30 inches, is the standard penetration resistance value (SPT-N). This value is used to
estimate the in -situ relative density of cohesionless soils and consistency of cohesive soils.
An automatic SPT hammer was used to advance the split -barrel sampler in the borings
performed on this site. A greater efficiency is typically achieved with the automatic hammer
compared to the conventional safety hammer operated with a cathead and rope. Published
correlations between the SPT values and soil properties are based on the lower efficiency
cathead and rope method. This higher efficiency affects the standard penetration resistance
blow count (N) value by increasing the penetration per hammer blow over what would be
obtained using the cathead and rope method. The effect of the automatic hammer's efficiency
has been considered in the interpretation and analysis of the subsurface information for this
report.
The samples were tagged for identification, sealed to reduce moisture loss, and taken to our
laboratory for further visual examination and classification. Information provided on the boring logs
attached to this report includes soil descriptions, consistency evaluations, boring depths, sampling
intervals, and groundwater conditions. The borings were backfilled with auger cuttings prior to the
drill crew leaving the site.
A field log of each boring was prepared by the drill crew. These logs included visual classifications
of the materials encountered during drilling as well as the driller's interpretation of the subsurface
conditions between samples. Final boring logs included with this report represent the engineers
interpretation of the field logs and include modifications based on laboratory observation and tests
of the sample.

GENERAL NOTES
• DESCRIPTION OF SYMBOLS AND ABBREVIATIONSnX
DESCRIPTIVE SOIL CLASSIFICATION
Soil classification is based on the Unified Soil Classification System. Coarse Grained Soils have more than 50% of their dry
weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have
less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are plastic, and
silts if they are slightly plastic or non -plastic. Major constituents may be added as modifiers and minor constituents may be
added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined
on the basis of their in -place relative density and fine-grained soils on the basis of their consistency.
LOCATION AND ELEVATION NOTES
Unless otherwise noted, Latitude and Longitude are approximately determined using a hand-held GPS device. The accuracy
of such devices is variable. Surface elevation data annotated with +/- indicates that no actual topographical survey was
conducted to confirm the surface elevation. Instead, the surface elevation was approximately determined from topographic
maps of the area.
