Re: Highland Forest
Revised request for NWP 29 & GC 3890 and response to USACE letter
Action ID #SAW -2017-01568
Sage Project #2017.31
This purpose of this letter and its attached exhibits is to provide a response to the letter received
from Mr. James Lastinger of the USACE on December 21, 2017. The revised site plan (see
attached) has been further modified to address Mr. Lastinger's concerns. A revised PCN form is
attached that reflects the revised site plan. Mr. Lastinger's comments from the December 21,
2017 letter are numbered below and the project engineer's response follows in red.
Boring studies submitted with the PCN indicate non-scourable rock was located at 9-15 feet deep at
the bottomless arch crossing locations. Based on previous experiences with the use of bottomless arch
culverts in the Raleigh Field Office, the Corps no longer looks favorably upon their use as typically in
the piedmont and coastal plain non-scourable rock cannot be reached and bottomless arch culverts
cannot be designed to NCDOT standards, which typically require non-scourable rock to be located
within 6 feet of the surface. Please submit information for feasibility of bottomless arch culverts in
the proposed locations, as well as information explaining if bottomless arch culvert meets NCDOT
design standards.
Response: The site plan has been revised in order to reduce number of Arch Adverts. Only I Arch culvert
remains, the 2nd crossing along Highland Forest Drive. Proposed culverted crossing lengths were shortened
in order to reduce total stream impact to under 150 If. Please see boring B-6, the closest boring to the
remaining crossing. (Exhibit E) Hard rock in excess of 50 blows per 5" exists in this area. Auger refusal was
noted at 5' from the surface. Soil is very rocky and non-erosive in this area. All arch culvert footers are
required to be designed by a Professional Engineer for all Town of Fuquay-Varina roadways. All internal
roadways to the site will be built to Town of Fuquay-Varina Standards and Specifications and maintained by
the Town. All culverts and arch structures are required to go through a separate 'building permit' submittal
to the Town prior to installation for the Town Engineer's review.
Highland Forest (01-22-18 response/revision) Page 1 of 3
2. Furthermore, The Corps has in the past advocated for the placement of bottomless arches, but has
since urged caution on their use due to several examples of structural failure, and severe degradation
of stream channels under the arches in the process due to vegetation loss and bank failure from over
shading, head cuts which may lead to severe erosion and structure failure. Should the applicant elect
to use a bottomless arch culverts, mitigation for the stream channel under the arch will be assessed at a
1:1 ratio due to secondary adverse impacts to the stream channel under the arch.
Response: Site has been revised to reduce number of arch culverts. Only I arch culvert remains, which has
also been further redesigned in order to reduce the likelihood of stream degradation under and around the
culvert. Please see Exhibit D. Arch culvert span has been widened to 18'. Site has been revised to increase
height from arch top to channel bottom. which is now in excess of 10' for sunlight penetration and air
circulation. Soils in area of culvert are very rocky and non-erosive. The Town of Fuquay-Varina will require a
scour analysis from design Engineer with culvert approval package.
3. Please provide a compensatory mitigation plan for proposed impacts to 0.1 acre of jurisdictional
wetlands.
Response: The site has been further revised and wetland impact area I has been eliminated. The site is
now only impacting 0.0956 ac total. Please see response to ft -6.
4. Please provide further justification for the need to crossing the existing stream channel twice at the
bottomless arch locations, instead of utilizing one crossing and cul-de-sacs, to further avoid and
minimize impacts to jurisdictional features.
Response: The Town of Fuquay-Varina's Land Development Ordinance will only allow for a
maximum block length of 500' (Exhibit B) and a maximum cul-de-sac length of 500' for Open Space
Developments (Exhibit F). A roadway network connection is required to the adjacent Ryan Place
Subdivision to the North (Exhibit A). The site engineer originally had a different layout that was not
approved due to all the aforementioned restrictions placed on the development. Every effort was made
to minimize the number of stream crosshws associated with this project and keep the project viable.
The project has over 50% open space. Over 3 acres of developable land is not being utilized in the
northwestern quadrant of the site as well as 3 acres to the south in order to avoid an additional stream
crossing and minimize overall impacts. Access from the Bowling Road public right-of=way to the
aforementioned areas would not be permitted by NCDOT due to proximity from other entrances.
5. It appears that there are utility line impacts associated with sewer connection south of wetland
impact area 6. Please account for these impacts on plan sheets and the PCN.
Response: This connection will be directionally bored in order to not avoid wctland impacts.
6. Please provide further justification for lot fill at wetland impact areas 1, 2, and 3. It appears that
proposed lots in those areas have enough buildable upland areas to facilitate the reasonable
construction of appropriate sized houses and accesses without the need for wetland impacts.
Response: L.ot fill has been minimized to the fullest extent possible. The minimum 40x60' house footprint for
this development is now shown on the revised impact maps to provide further insight into building constraints.
Homes were pushed as close to the street as possible to the edge of the lot front building setback. Basement
lots, very minimal backyards and 2:1 fill slopes with stabilization matting were used near wetlands to minimize
impacts. The site has been further revised and Impact Area I has been eliminated entirely by the addition of a
retaining wall to bring the total wetland impact for the project to 0.0956 ac. A lot was not placed at wetland
impact 6 in order to minimize wetland impact. Fill results from elevation required at top of cul-de-sac due to
cover and rock. See Boring B-6. 2:1 fill slope from road with synthetic stabilization utilized. Retaining wall
Highland Forest (01-22-18 response/revision) Page 2 of 3
placed at bottom of slope to further reduce wetland and 100 -yr floodplain from Kenneth Creek. Please see the
attached revised impact maps.
Mitigation
No mitigation has been proposed due to permanent stream impacts not exceeding 150 LF and
permanent wetland impacts not exceeding 0.1 acre. The Project is not within a NCDWR regulated
buffered basin therefore no buffer mitigation is proposed.
If you have any questions, please call me at (919) 559-1537.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Proposed'subdivision roads were aligned so as to avoid impacts to streams -and wetlands. as much as possible. Higher
wingwallswill 'be used in an effort to decrease the. length of stream impact of the two culverted crossings. An open
bottomed culvert will be used in one location to avoid, piping the, stream and thereby reduce impacts. The open bottomed
culvert crossing will use a higher and,longer span with a narrow width (spans 73 LF of stream channel) in an effort to
allow daylight to penetrate the area beneath the crossing. The two crossings of the same stream .(one is the open -
bottomed culvert) cannot be reduced to a single crossing with a longer cul-de-sac because the resulting road would
exceed the, Town of Fuquay-Varina's allowances for cul-de-sac lengths (500 feet).
A sewer line proposed in the Southeastern portion of the,property will be directionally bored beneath a wetland in order to
avoid wetland,impacts.
The impacts shown on the attached impact maps have been reduced significantly from the ,initial site plan in an effort to
minimize and avoid impacts. Lot layouts were reconfigured to require less wetland fill.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
f
Construction fencing will be used to define the construction corridor and prevent any.accidental additional impacts. Silt
fencing and temporary basins will also be used to prevent sediment runoff into the streams and wetlands. Headwalls will
be constructed in several locations adjacent to road crossings and lots.so as to further reduce impacts.

Re: Report of Subsurface Investigation
Proposed Bowling Road Subdivision Sanitary. Sewer Improvements
Fuquay,-Varina; North Carolina
GeoTechnologies Project No. 1 -17 -0557 -EA
Gentlemen:
GeoTechnologies, Inc. has completed the authorized investigation to evaluate soil conditions for the
proposed 'Bowling Road subdivision at 1455, Bowling Road, in Fuquay-Varina, North Carolina.
GeoTechnologies completed ten soil test borings along the proposed sewers and roadways. to evaluate the
potential for shallow rock excavation. The borings were completed at the locations ind'i'cated on ,the attached
Table 1 and Figure 1. The borings were located in the field using NC grid coordinates with a hand-held Trimble
GPS unit. Elevations were estimated from topography on the Wake County GIS website. As such, the indicated
locations and elevations should be considered approximate. The borings were completed with an all -terrain
vehicle, mounted :drill rig turning large diameter hollow stem augers. Soils were sampled at selected intervals
using standard penetration testing techniques outlined in ASTM D-1586. The borings were extended to depths
of about 9 to 18.5 feet below existing grade. This report presents the findings of the investigation and our
recommendations regarding excavation for the proposed sewer line and roadway construction considerations.
SITE AND PROJECT INFORMATION
It is our understanding that the project will involve construction of a new residential development at
1455 Bowling Road in Fuquay-Varina, North Carolina. The project will include construction of streets and.
sewer line to service 90 single family lots. The sewer inverts have not been established at this time; however,
based on our conversations with the Civil Engineer, we understand that cuts will likely be about 15 to 20 feet.
The site is currently undeveloped and consists of woodlands, with the exception of a power easement
that crosses the site. A creek flows across the eastern end of the site and a creek is also located near the western
site boundary. Topography on the site generally slopes to the south with elevations ranging from just over 360
feet to just over 270 feet.

SUBSURFACE CONDITIONS
A generalized subsurface profile prepared from the test boring data is attached to this report as Figure 2
to graphically illustrate subsurface conditions encountered at this site. More detailed descriptions of the
conditions encountered at the individual test boring locations are then presented on the attached test boring
records.
Subsurface. conditions on the site were characterized by the presence of near surface topsoil with a
thickness of 3 to 12 inches. The topsoil was typically underlain by ;residual soils that were formed in place by
weathering of the parent bedrock. An exception was at boring B-1 where the upper 6 feet appeared to be a sandy
fill material with trace organics. Penetration resistances in the fill varied from 3 to 7 blows per foot (bpf). The
residual soils typically consisted of firm to hard clay and. silt that became siltier with increasing depth.
Penetration resistances in the residual soils varied from 7 to 59 bpf. Borings B-1, B-7, B-9 and B-10 were
terminated at 15 feet -in residual soils. However, the remainder of the borings encountered partially weathered
rock (PWR) at depths of 2.5 to 12 feet. PWR is defined as material that can be penetrated with the soil drilling
augers but that exhibits penetration resistances in excess of 100 bpf. The PWR transitioned to harder rock and
auger refusal was encountered on hard rock at 9 to 18.5 feet below grade in borings B-2 through B-6.
Groundwater was encountered in boring B-1 at 6 feet below existing grade. No groundwater was
encountered in the remainder of the borings at the time of boring completion. However, the fine grained near
surface soils are, conducive to the development of a temporarily higher perched groundwater condition following
periods of inclement weather.
AREA GEOLOGY
The site is located in the Coastal Plain Physiographic and Geologic Province of North Carolina.' The
near surface soils in the area of the site generally consist of sands, clays, and silts which have eroded from the
Piedmont Uplands and been deposited by streams. More specifically, the site is located within- the Middendorf
Geologic Formation which is comprised of sand,. sandstones, and mudstones which were deposited during the
Cretaceous Period approximately 63 to .138 million years ago. Frequent migration of the shoreline over the last
two million years have redistributed the sedimentary soils originally deposited by streams and has resulted in the
fairly Coastal Plain topography. "
RI 1133 LLI1 _ =
The following recommendations are made 'based upon a review of the attached test boring data, 'our
understanding of the proposed construction, arid. past experience with similar projects and subsurface conditions.
Should alignment plans change significantly from those; now under consideration, we would appreciate being
provided with that information so that these recommendations may be confirmed, extended, or modified as
necessary. Additionally, should subsurface conditions adverse to those indicated by this, report be encountered
during construction, those differences should be reported to us for review and comment.
Site Grading Considerations. The soils at: existirig grade are moisture sensitive and will be difficult to
compact during the wetter winter months of December] through April or May. To avoid delays during site

Re: Bowling Road Subdivision Sanitary Sewer Improvements

grading operations, we recommend that earthwork activities be scheduled after May and prior to December if
possible, in order to facilitate site grading work.
Site grading should begin with the removal of all vegetation and topsoil from those areas designated for
construction of building and pavement areas. Based on the results of the soil test borings, we anticipate that
topsoil thickness will generally be on the order of 3 to 12 inches; however due to the heavy tree cover on
portions of the site, somewhat deeper stripping thicknesses may be required in some areas to remove tree root
bulbs. Additionally; it is possible that some deeper topsoil could be encountered in old plow zone areas. Once
stripping is completed, we recommend that any at grade areas or areas designated to receive fill be proofrolled
with a partially loaded dump truck or similar piece of rubber tired equipment to identify areas necessitating
additional repair. Any area that ruts or pumps excessively in the opinion of the engineer should be undercut to
firm bearing or be repaired as directed by the engineer. These repairs can likely be implemented by discing,
moisture conditioning and recompacting the near surface materials. Although some repair will be needed
anytime of the year, repair quantities can be minimized by scheduling grading activities during the wanner
months of the year. The near surface soils at this site are moisture sensitive, and grading during a wet period of
the year will increase the need for undercut type repairs.
The on-site materials, excluding topsoil, should be suitable for reuse as structural fill provided
compaction moisture can be maintained near optimum. The contractor should be prepared to moisture condition
the soils as necessary in order to achieve adequate compaction. Off-site borrow should consist of clayey or silty
sands or low plasticity silts and clays having a Unified Soil Classification of SC, SM, ML, or CL. Fill soils
should be compacted to not less than 95% of the standard Proctor maximum dry density, except in the final foot
where this requirement should be increased to 98% of the standard Proctor maximum. Moisture contents should
be maintained within about 2 percent of optimum moisture content to facilitate compaction and to maintain
stability of the fill section.
General Excavation Considerations. As previously discussed, partially weathered rock and hard rock
was encountered in borings B-2 through B-6 and B-8 and it is possible that areas of shallower rock outcrops will
be encountered intermediate of the borings on the si , It has been our experience that partially weathered rock
materials can generally be ripped with a large dozer such as a CAT D8 or equivalent equipped with a single
tooth ripper provided penetration resistances are no higher than 50 blows per 2 inches. PWR harder than 50
blows per 2 inches of penetration generally requires blasting to remove. The PWR rock encountered in boring
B-5 quickly transitions to hard rock that and cannot be ripped.
The equipment utilized for installation of utilities and foundations is less powerful and blasting is
typically required for excavation into the partially weathered rock. A large track hoe such as a CAT 320 or
equivalent equipped with rock teeth can excavate materials having standard penetration resistances in the range
of 50 blows per 4 inches to 50 blows per 6 inches. However, the rate of excavation is slow and utility
contractors will typically request a trench rock price for excavation of any partially weathered rock materials.
Light blasting of these materials will expedite utility installation.
Pipeline Bedding and Trench Backfilling. If any rock is exposed at invert elevation, we recommend that
the pipe be placed over at least 6 inches of open graded stone such as #57 stone in order to provide a leveling
cushion for the base of the pipe. Shallow rock at the bedding elevation even with six inches of over excavation
will increase stresses in the pipe due to the low compressibility of the foundation. If any areas of soft soils are
encountered in the base of the excavation, the trenches should be overexcavated approximately 12 to 18 inches
and be backfilled with washed stone. All backfill placed over the pipe should be compacted to at least 90% of
. GeoTechnologies,lnc.
Spaulding & Norris
Re: Bowling Road Subdivision Sanitary Sewer Improvements
July 12, 2017
Page: 4
the standard Proctor maximum dry density except where post -construction settlement of backfill cannot be
tolerated. If any settlement sensitive areas exist, backfill in those areas should be compacted to 95% of the
standard Proctor maximum dry density. The initial lift of soil over the, pipe should consist of soil and not contain
rock or weathered rock to serve as a cushion over the pipe for subsequent fill placement and compaction. Soils
excavated from the trench may be utilized as backfill provided it can be suitably compacted.
Construction Considerations. We recommend that all OSHA regulations lye strictly adhered to during .
installation of the sanitary sewer line. The soils will classify as a type `B" material which will generally require
temporary side slopes of 1H:1V, except where shallow groundwater is encountered and the temporary side
slopes will need to be flattened to 1.5H: IV. If insufficient room exists for maintaining those side slopes; we
recommend that the contractor be prepared to utilize temporary shoring such as a trench box during installation
of the sewer line.
Dewatering Considerations. At the time .that borings were completed, groundwater levels were generally
below the boring termination depth. Groundwater was encountered in boring B-1 at 6 feet below existing grade.
In areas where groundwater is encountered a pump and sump placed within the excavation will likely be
adequate for the minor quantities of seepage which will occur. The need for dewatering and type of dewatering
will need to be determined by the contractor as the installation progresses.
- Foundation Support Considerations. Following proper ,grading (including repair of any soft near surface
soils subsurface conditions encountered on this site are conducive to the use shallow foundations for
support of the proposed residential structures. The majority of the soils which were encountered in theborings
will exhibit a bearing capacity. of 2,000 psf and a subgrade modulus of 100 pci, and properly compacted
structural fill will exhibit a similar bearing capacity. We recommend that each individual lot be tested during
construction to verify that the required bearing capacity is. available.
We recommend all footings bear at least 18' inches below finished grade for frost protection. We
recommend that all foundation excavations be inspected by a'geotechnical engineer to verify that the exposed
subgrades soils have adequate strength to support the anticipated loads.
Slope Recommendations. We recommend that- maximum slope angles for fill -slopes not exceed 3H:1 V
with maximum, cut slopes not exceeding 2.5H:1 V. All fill material placed in slopes should be properly
compacted as previously discussed. Additionally, surface water runoff should be directed away from slopes.
r
General Pavement Design Consideration.. No laboratory CBR testing was performed. However, based
on our experience in the area, we expect that CBR ,values of the lower plasticity onsite soils would be about 5 to
6 percent. If provided with anticipated traffic loading information, we will be happy to prepare a design.
pavement section.
The most important factors affecting pavement life in the area of the site are the condition of the:
subgrade immediately prior to base course stone',placement and post construction drainage. We recommend that
the subgrade of all pavement areas be proofrolled and that any yielding areas be identified and repaired prior to
placement of the base coarse stone. All subgrade soils 'should be re.compacted to a minimum of 100% of the
standard Proctor maximum dry density immediately',,prior;to.base course stone placement where appropriate. We
recommend that all pavement areas be properly graded' to promote run-off of water and to prevent ponding of
water on the pavement surface which can lead to eventual saturation of subgrade soils and the loss of pavement
support.

Segmental Type Retaining Walls. Our experience has been that the rine grained soils on this site are not
particularly well suited for use as backfill in the reinforced zone. We recommend importing quarry material,..
such as screenings ,or washed stone for use in the reinforced zone of segmental walls.
Seismic Design Considerations. This site is a site class "D" relative to seismic design considerations.
SUMMARY
In summary, subsurface conditions at the test boring locations are characterized by near surface residual
soils that transitioned to'PWR at depths of 2.5 to 12 feet in 6 of the 10 borings. We anticipate that blasting will
be required to excavate the PWR in trench excavdtions.
