This letter is to advise you of recent arisen meats to the North Carolina Mining Act of 1971 which impact t� e
permit term of your existing mini-ig permit Pursuant to the passage of House Bill 56, whsa became IaW on October 4,
2017 as SL 2017-209, all existing mining permits and any newly issued mining permits are to be issued for the life of site
or for the duration of the lease term. The "life of site" means the period from the initial receipt of a permit for the operation
until the mining operation terminates and the required reclamation is completed,
Considering the above, this letter hereby modifies your existing mining permit to remove all references to the prior
expiration date to convert Your permit to 8 life of site or lease permit effective immediately. No action is required can your
part for this modification to be effective, Please attach this letter to your existing minin ermit for future reference. The
mine name and permit number on the permit document, and all existing operating and reclamation conditions contained
therein. shall remain in full force and effect. Furthefrriore, all provisions of GS §74-51 and GS §74-52 still apply to ail new,
transferred and modified mining permits.
In Addition to the life of site or lease mining permit provision, SL 2017-209 also enacted a new annual mining
permit operating fee of $400 per mining permit number. By statute, the initial payment of this annual $400 fee must be
submitted to this office by December 31, 2017 — see the attached lnvcioe to remit the initial annual fee payment by this
deadline. Beginning in 2018 the $400 annual operating fee must be submitted by July 1 of each year with the required
Annual Reclamation Report as required by GS §74-55. Failure to submit the fee by the required deadline will result in a
$501month late fee and could result in the denial of future permit acions and/or revocation of your mining permit.
Lastly, pursuant to GS §74-54, the cap on reclamation bonds has been raised from $500,000 to $1 million. Any
adjustments needed in existing bonds will be initiated by this office or addressed during your next requested permit action
unless you contact this office wit` i a written request to have your bond reevaluated.
The issuance of a mining permit and/or any modification to it does not supersede local zoning regulations. The
responsibility of compliance with any applicable zoning regulations rernains with you
Thank you for your cooperation in tI, is matter. If you have any questions on the above, please contact Ms. Judy
Wehner, Assistant State Mining SpeGialist, or me at [phone].

Mell-
As we discussed today, past experience building rock buttress structures at North Buncombe Quarry has shown that the
average depth of overburden is 5-10 ft. Because the overburden is shallow in the proposed area for the structure, the
possibility of rotational failure can be eliminated. If you have any more questions regarding the application, please do
not hesitate to contact me. Thanks.

Mell-
I have re -calculated the design for the rock buttress proposal a few different ways. After reviewing these
calculations I believe you will see that our design is done the most conservative way possible.
The first way I calculated the area used the actual G11 area of 1300 sf vs the 3500 sf I used for the design.
Calculated the boulder area this way shows that only 340 sf of boulders are required verses the 915 sf of
boulders per unit thickness used for design purposes.
I also calculated the possibility of the slope failing at 60, 45, and 30 degree angles from the toe of the slope.
The 30 degree angle required the most boulders at 575 sf per unit thickness. This is well below the 915 sf of
boulders used in the design.
I will call you shortly to discuss these calculations. Thanks.

Dear Mr. Conner:
Beverly Eaves Perdue, Governor
Dee Freeman, Secretary
We have reviewed the modification request youlyour company submitted for the
referenced mine site. However, the following information is needed to continue processing
your application:
The cross section must match the plan view. The 2000 foot contour is not
accurately shown on the plan view if there is a flat area on top of the fill area. In
addition, the cross section show a 1:1 slope and the plan view shows a 2:1 slope.
Revise the plan view to show accurate contours and revise the cross section to
show a 2:1 slope.
2. Show how you determined the area of the fill and rock in the slope stability
calculations. It appears (112)bh was used to compute the area but the area does
not appear to be triangular in shape. Please clarify.
Please be advised that our review cannot be completed until all of the items listed
above have been fully addressed. In addition, please note the Land Quality Section may
request additional information, not included in this letter, as the mining application review
progresses.

FROM: Dave McHenry, Mountain Region Coordinator
Habitat Conservation Program
DATE: September 23, 2011
SUBJECT: Mining Permit Modification for B.V. Hedrick Gravel and Sand Company
North Buncombe Quarry
Mining Permit No. 11-07
Staff with the NC Wildlife Resources Commission (Commission) reviewed the application to modify the
permit for the 277-acre North Buncombe Quarry to construct retaining walls. Comments from the
Commission are provided under provisions of the Mining Act of 1971 (as amended, 1982; G.S. 74-46
through 74-68; 15 NCAC 5) and the North Carolina General Statutes (G.S. 113-131 et. seq.).
Reems Creek adjacent to the mine does not support trout. However, the French Broad River a short
distance downstream supports some rare aquatic species. A portion of the mine is part of the locally
significant Reems Creek Gorge Natural Heritage Area. Land Quality may wish to consult with the
Natural Heritage Program for details about this area and the resources it supports.
It appears that the proposal will not directly impact streams. The terrain between the proposed boulder
walls and Reems Creek appears very steep. Due to the terrain, the narrow vegetated buffers that are
dedicated along Reems Creek would likely restrain little sediment run-off. However, the Commission
does not anticipate undue adverse effects of this mine permit modification on fish and wildlife resources
provided erosion and storm run-off controls for the new construction are effective.
Thank you for the opportunity to review and comment on this permit action. Please contact me at (828)
452-2546 extension 24 if you have any questions about these comments.

Please find attached a copy of the mining permit modification request for the above referenced project.
The North Buncombe Quarry permit modification request does not appear to have an unduly adverse effect on
ground water supplies. However they will need to continue reporting their water withdrawal reports required by
North Carolina General Statute G.S. 143-215.22H.
Facilities not in the fifteen county Central Coastal Plain Capacity Use Area are required to register their water
withdrawals in accordance with the North Carolina General Statute G.S. 143-215.22H. This statue requires any
non-agricultural water user who withdraws 100,000 gallons or more in any one day of ground water or surface
water to register and update withdrawals. This statue also requires transfers of 100,000 gallons or more in any
one day of surface water from one river basin to another river basin to register and update their water transfers.
Water withdrawal registrants must complete the annual water use reporting form by AprilI for the previous
year.
If you have further questions please contact the Division of Water Resources at [phone] or send

Summary
Hedrick Industries is proposing the construction of a boulder retaining structure at its
North Buncombe Quarry. The quarrying process produces a large amount of excess dirt. Due to
the unique requirements of the space available at this site a limited area to put fill dirt is
available. We plan to construct the rock dam to provide a place to store fill material on site.
The proposed structure is located on property owned by Hedrick Industries North
Buncombe Quarry. The total project area will affect 4.6 acres of the property. The rock buttress
will be located on the toe of a I 3° slope. The structure has been designed to safeguard against
failure (4).
ThiQ @tr1Vlctlure will be located d);U-Cent to similar s........ m � ' Tull "201 ,
aUJuvbll4 w a 3iiililat ski 11�.LU1G perlill tleU 1i1 July UI GVI V.
This new structure will not affect any of the design elements in the previously permitted
structure.
Tl►e intended construction sequence for this project has been laid out in this proposal.
The construction sequence is provided to show the order with which the company intends to
complete major construction activities. The construction sequence has been designed to get
vegetation on disturbed areas as soon as possible as well as other necessary steps to prevent
erosion control problems.
The area for the construction of this structure required some unique design
considerations. The drainage on the site will require the use of two basins to capture all possible
run-off. As stated previously the area for construction of this structure is very limited. Due to
the fact that the structure is located at the toe of a steep hill and in order to minimize the changes
to the natural slope, we are proposing construction of two sediment basins. Design
considerations will be discussed in the sediment basin section.

Slope Stabilization Calculations
Project: B. V. Hedrick Industries, North Buncombe Quarry
Generated by: Haynes P. Gaston
Date: June 7, 2010
To prevent a failure we propose using a boulder retaining structure to oppose the sliding force of
the fill slope. As a conservative approach, we shall size the boulder stack using the sliding force
of the entire fill wedge. Normally only a portion of the fill would slide while friction forces
between the fill and the natural grade would prevent the entire fill from sliding. However, for
this design we shall treat the wedge as a singular solid.
The ,area for ;-Stallatio n of the fill Chas two swales iri it. Both swaies are analyzed two determine
the appropriately sized boulder retention structure to prevent movement. The structure will be
built to the more stringent needs of section AA.
Section AA
Input Data:
Unit Weights (p)
Fill Soils —110 pounds per cubic foot (pcf) (completely saturated)
Stone —140 pcf

Between fill soil and natural grade —0.2
Between boulders and natural grade —0.6
Unit Thickness (t) —1 ft
Natural Slope —16.7° average slope of natural ground over length of fill area
Fill Slope — 26.6°
Step 1: Area of Fill Wedge (Af)
Af = (%)bh = % * (153 ft.) * (45 ft.)
Af = 3,500 sf
Step 2: Resultant Sliding Force of Fill Wedge (Ff)
Ff = Sliding force of wedge — frictional force (ff)
Ff = Wf*sin Q - ff
Where, Wf = weight of wedge
pf * Af-* t

110 pcf * 3,500 sf * 1 ft
385,000 ibs,.,
ff - p * W f * cos t
Ff=Wf*sin 6-µ* Wf*cos 9
Ff = (385,000 Ibs * sin 16.7°) - (0.2 * 385,000 Ibs * cos 16.7')
Ff = 110,600 Ibs - 73,800 Ibs
Ff = 36,800 Ibs
Step 3: Weight of Boulder Retention Structure
Slide Force of Fill Wedge = Friction Force on Boulders - Slide Force -of Boulders
Ff-µ*vv6*cost- a*sine
or
Ws=Ff+(µ*cos h--sin BJ
We = 36,800 lbs + (.6 * cos 16.7° - sin 16.7°)
We = 128,000 Ibs
Step 4: Sectional Area of Boulder Pile Required
AB - We —' pBt
�A =128, Ibs + (140 pcf * 1 ft) ,
�A�B=914sf�
Step 5: Design Dimensions of Boulder Pile
As = % * (top width + bottom width) * height
*Height at design section (h) = 30 ft and top width = 15 ft
Yields a bottom width = 75 ft
With these dimensions,
As=Y2,*(15+75)*30
As = 1350 sf
• This yields a Safety Factor of (11350 sf + 914 sf) = 1 ,5
This design is acceptable

Unit Thickness (t) —1 ft
Natural Slope —13.1" average slope of natural ground over length of fill area
Fill Slope — 26.6"
Step 1: Area of Fill Wedge (Af)
Af = (Yi)bh = Yx * (302 ft.) * (70 ft.)
Af = 10,570 sf
Step 2: Resultant Sliding Force of Fill Wedge (Ff)
Ff = Sliding force of wedge — frictional force (ff)
Ff = Wf*sin A - ff
Where, Wf = weight of wedge
pf*Af-*t
110 pcf * 10,570 sf * 1 ft
1,162,700 Ibs
ff = µ * Wf * Cos()
Ff=Wf*sin A—µ*Wf*cosA
Ff = (1,162,700 Ibs * sin 13.1") — (0.2 * 1,162,700 Ibs * cos 13.1°)
Ff = 263,500 lbs — 226,500 Ibs
Ff = 37,000 Ibs
Step 3: Weight of Boulder Retention Structure
Slide Force of Fill Wedge = Friction Force on Boulders — Slide Force of Boulders
Ff=p*WB*cos 6-WB *sin 6
or
WB=Ff-(µ*cos 6—sin A)
Wa = 37,000 Ibs - (.6 * cos 13.1° - sin 13.1°)
Wa = 103,500 Ibs
Step 4: Sectional Area of Boulder Pile Required
M.

As = We _ pet
AB = 103,500 Ibs _ (140 pcf * 1 ft)
Ae = 740 sf
Step 5: Design Dimensions of Boulder Pile
AB = %: * (top width + bottom width) * height
*Height at design section (h) = 27 ft and top width = 15 ft
Yields a bottom width = 69 ft
With these dimensions,
As=%:*(15+69)*27
AB = 1134 sf
0 This yields a Safety Factor of (1134 sf + 740 sf) = 1.5
o Although this design is acceptable for the swale at section BB, the more
stringent design for the swale at section AA will be used for construction.

Sediment Basin Design Changes
To minimize the amount of fill that has to be brought in for sediment basin construction we are
proposing modifying the standard sediment basin design. The area we plan to construct the basins in
will not have the required length of 80' and 92'. In order to address this issue we are proposing splitting
the basins into a "y" like shape (Fig 1).

This design will allow the basin to retain the same design properties in terms of surface area and
volume, while reducing the required distance of the basin. Maintaining the appropriate design distance
will ensure that sediment settles out of the water and is not released from the site.

Raleigh, NC 27699-1612
Permit: 11-07
Dear Ashley:
Rr- c D
SEEP .15 ?Atn
I have included the requested information for the modification at our North Buncombe
Quarry facility as stated in the letter dated August 30, 2010. I will address each request
individually below.
1. The maps have been revised to show the access road to the newly disturbed area.
There was an old logging road in this area that will be used for accessing the area and
will be maintained for the continued maintenance of the sediment basins. During
construction of the access road silt fencing will be installed to protect any erosion during
a storm event. The road will be graded to the inside allowing any runoff to be treated by
the sediment basins.
2. A new affected acreage chart has been included with the mapping. We will be
disturbing an additional 3.1 acres. The new disturbed acreage for permit 11-07 will be
185.09.
3. Silt fencing will be used at the outlets of the sediment basins during the construction
of the basins but will be removed once the basins have been constructed and stabilized.
4. :::e gra —.. of "-: Lwv m aiie has been added to the Bross section of A -A. Ti1C
material used will consist of shot rock material that will not be greater than 4' in
diameter. The material will also consist of rocks less than 4' feet down to 6" inch
material that will have some fines intermixed. The material will be at a minimum of 140
pcf in place. This is the same material that has been used on the previous 3 boulder walls
that have been permitted at this location.
5. I have contacted Susan Wilson with DWQ and have sent her a copy of the latitude and
longitude of the stream head location. I have placed the lat and long of the stream head
on the map.

6. I have included a larger area of the topography surrounding the proposed boulder wall.
I have shown on the map a berm that channels water from the above stockpile and fill
area into basin SB002. The mapping used for this project was developed by Tuck
Engineering and this area is very dense and was difficult to determine topographic
information. I have shown on the map the directional flow of water along the Power Line
right-of-way from field observations. Due to the directional flow and existing berm
directing water away from the project area the drainage area of 2.6 acres is accurate.
7. Comments from Rick Wooten with NC Geological Survey
The area will be timbered and grubbed to virgin soil material. The material is hard
clay that is consistent with the other previously approved boulder walls. The boulder
wall will have smaller material but will be free draining eliminating excessive pore -water
pressures. The boulder wall will have a bearing capacity of 20,705 tons. Mr. Wooten
had some concerns about the numbers used in the calculating of the slope stabilization.
From our experience in designing and construction of 3 previous boulder walls in this
area we are confident that the numbers used are accurate. We also feel that keying in the
boulder wall to a minimum of 10 feet is adequate to prevent any failure due to the
materials on the existing slope.
The boulder wall modification being requested has been designed to the same criteria as
the previous three permitted boulder walls. Hedrick Industries is confident in the
numbers used to calculate the stability of the boulder wall structure. This boulder wall is
805' from the last boulder wall approved on March 19, 2009.

Boulder Wall Construction Sequence s
Revised September 10, 2010
• Establish property boundaries, buffers, and all offsets before beginning any clearing or
construction of any structure.
• install silt fencing as designated on Boulder Wall map.
• Timber and grub areas for construction of access road and sediment basins.
• install riser/barrel sediment basin with skimmer to the specified dimensions per design
calculations. Refer to attached drawings from the NC Erosion and Sediment Control
Planning and Design Manual. Refer to manufactures specifications for the installation of
skimmer.
• After completion of sediment basins complete timbering and grubbing area to virgin soil
in project area.
• Construct key for the boulder wall. Excavate a minimum of 10 feet in depth and a
minimum of 30 feet in width.
• Before placing any fill material behind boulder wall the boulder wall must be at a
minimum of 10 feet in height and constructed as specified per design calculations and
drawings.
• Fill material will be placed in 2 foot layers and tracked with heavy rollers, or crawler
equipment for compaction.
• Fill material shall always be 2 foot below the boulder wall. When fill material reaches
the 2 foot mark the boulder wall shall be raised to enable more fill material until it
reaches its maximum height of 30 feet.
• When the boulder wall reaches its maximum height the fill material will then be brought
up in lifts as shown on the design sheets maintaining a 2 to 1 slope until the elevation of
2015 is reached.
• Once placing of fill material is complete the diversion ditches shall be constructed
uaa� w u�Ol LL.
• 4 inches of topsoil shall then be placed over fill area and seeded according to the
submitted seeding schedule.

Dear Mr. Conner:
Beverly Eaves Perdue, Governor
Dee Freeman, Secretary
We have reviewed the modification your company submitted for the referenced mine
site. However, the following information is needed to continue processing your application:
1. Revise your Drainage Area & Boulder Wall Design map to show how you will
access the proposed new disturbed area. There will, at a minimum, need to be a
road for access and measures along the road for sediment and erosion control.
Provide more information and construction details as necessary.
2. Provide a new affected acreage chart for this permitted site, which includes new
disturbed acreage from this modification request.
3. Please clarify- why you are showing silt fence at the outlets of the two sediment
basins. Is the silt fence to be removed after the basins are in place and the
disturbed areas around them stabilized?
4. Please provide information on the gradation of the rock size to be used for the
construction of the boulder wall. Revise cross section A -A on the Drainage Area
& Boulder Wall Design map to provide more detail on the rock sizing.

Review Comments on the proposed boulder wall design for the North Buncombe Quarry,
June 2010.
The boulder wall design may be adequately stable, and the values used in the analysis
may be reasonable and conservative; however, this could not be determined from the
information provided.
Specific items related to the stability of the slope could not be evaluated with the
information provided as follows:
1. The origin, nature and geotechnical properties of materials on the existing slope
beneath the fill and boulder wall. .
2. The effect of pore -water pressures in the fill and existing materials on the stability
of the slope. Presumably the boulder wall itself would be free draining.
3. illy external stability of Me 1111 and wall on ine slope, including a bearing
capacity failure of the wail itself.
Other comments:
Surface preparation methods to be used on the existing slope prior to placement of the fill
were not specified.
Keying the wail into the existing slope as shown is generally advantageous; however, the
depth and configuration of the key depends in part on the materials on the existing slope.
Depending on the nature of the fill and its placement method, the saturated, in -place unit
weight of fill maybe greater than the 110 pcf used in the analysis. Similarly, a loose
bulk density of rock used for the boulder wall may be less than the 140 pcf used in the
analysis.
The 15' average slope of the natural ground of the fill area used in the analysis may be
less than the actual slope along a critical failure surface.

provided under provisions of the Mining Act of 1971 (as amended, 1982; G.S. 74-46 through 74-68; 15 �S

Reems Creek adjacent to the mine does not support trout. However, the French Broad River ashort -X 1� 0,
distance downstream supports some rare aquatic species. The land where the disposal is proposed is part CV
of the locally significant Reems Creek Gorge Natural Heritage Area. Land Quality may wish to consult �`�` 1r'
with the Natural Heritage Program for details about this area. �.��WOQII

It appears that the proposal will not directly impact streams; we recommend that this be verified by DWQ
personnel.
The Commission'does not anticipate undue adverse effects of this mine permit renewal bri fish,and.wildlife
resources provided sediment and erosion controls are effective and storm run-off does not cause -degradation
of the stream below the fill area, The drainage ditches may increase the run-off rate and elevate erosive
velocities. To help offset this, we recommend that the project either include an energy dissipater outside of „-; VIA $eS
the stream buffer or, more preferable, a level spreader to help reduce concentrated flow. r\,
The Commission also requests that erosion control and reclamation plans include planting that would benefit 00 5`71
wildlife resources. Sericea lespedeza and tall fescue, which are often listed in seeding plans, should be Q ,'l(rl
avoided because they are invasive and inhibit the establishment of native plants that are more valuable as p` . a --

1. Information submitted on slope stability needs to be submitted by a geotechnical engineer. We have asked for this in
the past on other sites.
✓2. Have them submit a new site plan with this area shown on there and new disturbed area chart.
,40 How are they going to access the new disturbed area - it is not shown? They need to include a road in the disturbed
area and it may be more than 2.6 acres (plus have them show it and measures along road).
* I have asked Rick Wooten to look over the slope material and will forward comments asap. I will be faxing water

Please find attached a copy of the mining permit modification request for the above referenced project.
The North Buncombe Quarry permit modification request does not appear to have an unduly adverse effect on
ground water supplies. However they will need to continue reporting their water withdrawal reports required by
North Carolina General Statute G.S. 143-215.22H.
Facilities not in the fifteen county Central Coastal Plain Capacity Use Area are required to register their water
withdrawals in accordance with the North Carolina General Statute G.S. 143-215.22H. This statue requires any
non-agricultural water user who withdraws 100,000 gallons or more in any one day of ground water or surface
water to register and update withdrawals. This statue also requires transfers of 100,000 gallons or more in any
one day of surface water from one river basin to another river basin to register and update their water transfers.
Water withdrawal registrants must complete the annual water use reporting form by April I for the previous
year.

Summary
riedrick industries is proposing the construction of a boulder retaining structure at its
North Buncombe Quarry. The quarrying process produces a large amount of excess dirt. Due to
the unique requirements of the space available at this site a limited area to put fill dirt is
available. We plan to construct the boulder wall to provide a place to store fill material on site.
The proposed structure is located on 1.7 acres of property owned by Hedrick Industries
North Buncombe Quarry. The total project area will affect 2.6 acres of the property. The rock
wall will be located on the toe of a IS' slope. The structure has been designed to safeguard
against failure.
The intended construction sequence for this project has been laid out in the plan. The
construction sequence is provided to show the order with which the company intends to complete
major construction activities. The construction sequence has been designed to get vegetation on
disturbed areas as soon as possible as well as other necessary steps to prevent erosion control
problems.
The area for the construction of this structure required some unique design
considerations. As stated previously the area for construction of this structure is very limited.
Due to the fact that the structure is located at the toe of a steep hill and in order to maintain a 50'
buffer off of the stream located below the structure, we are proposing constructing two smaller
sediment basins side by side. The design calculations show that the two smaller basins 33' x 64'
are more than adequate to provide the necessary erosion control measures to the 2.6 acres of
disturbed area.

Minimum Sediment Basin Criteria
Minimum Sediment Basin Volume (1,800 cf per acre):
Design basin volumes shall be at least 2 x Vmin
Sediment shall be removed when approximately half
of the basin's voiumt; is fiiied. Therefore, minimum
basin volumes shall always be met.
Vmin = 2,340 cf
Minimum Sediment Basin Surface Area:
The minimum surface area requirements for the sediment basin shall be determined by
requiring the ratio of basin surface area, Amin to peak inflow rate, Q25 to equal 0.01 ac per cfs,
or, Amin / Q25 = 0.01 ac/cfs
Amin = 2,060 sf
Design Area of Sediment Basin:
Requiring the length to width ratio of the basins to equal 2 allows for the formulation of the
following equation: Amin = L x W = 2W x W = 2W ; or, W = (Amin / 2)'2

W=33ft L=b4ft
Design Depth of Sediment Basin:
The minimum depth of the sediment basin can be determined by dividing the minimum volume
requirement by the minimum area requirement: dmin = Vmin / Amin
dmin = 1.14 ft
The design depth shall be equal to two times the minimum required depth to allow for cleanout
at half of the basin volume, while always maintaining Vmin.
d=5ft
Sediment Basin Design Calculations
Principal Spillway Design
The minimum barrel capacity shall be determined by the following relationship:
0.2 cfs per acre of disturbance.
Qpmin = 0.2 cfs
The principal spillway capacity must be evaluated in three ways:
a. Riser capacity acting as a weir
b. Riser capacity as an orifice
C. Barrel capacity as an orifice
a. Riser as a weir:
Q riser as weir = Cw * L * HA1.5
For Basin #1:
L = 2*II*(Riser radius)
H= l'
Diameter of riser = 18"
Diameter of barrel = 12"
Riser and barrel diameters are found by trial and error in the spreadsheet. Riser
diameter should be at least 1.5 times the barrel diameter to prevent vortex formation.

Q riser as weir = (3.33) * (2*IZ*(1.5)/2) * (1)A1.5 = 15.7 cfs
b. Riser as an orifice
Q riser as an orifice = Cd * A * (2*g*h)�0.5
For Basin #1:
Cd = 0.6 (Ref Malcom)
A = TI*(Riser diameter)A2

For Basin #1:
Cd = 0.6 (Ref Malcom)

Barrel diameter = 1.0'
g = 32.2
h=3'
Q barrel as orifice = 0.6 * rl*(1.0)A2 * (2*32.2*3)A05 = 5 cfs

Capacity of riser/barrel configuration is the minimum flow of the three cases
considered. Therefore, Qmax = 15 cfs, which is greater than the 2 cfs required.

SImStabilization Calculatigns
Project: B. V. Hedrick Industries, North Buncombe Quarry
Generated by: Haynes P. Gaston
Date: June 7, 2010
To prevent a failure we propose using a boulder retaining structure to oppose the sliding force of
the fill slope. As a conservative approach, we shall size the boulder stack using the sliding force
of the entire fill wedge. Normally only a portion of the fill would slide while friction forces
between the fill and the natural grade would prevent the entire fill from sliding. However, for
this design we shall treat the wedge as a singular solid.
Input Data:
Unit Weights (p)
Fill Soils — 110 pounds per cubic foot (pcf) (completely saturated)
Stone — 140 pcf
Coefficients of Friction (g)
Between fill soil and natural grade — 0.2
Between boulders and natural grade — 0.6
Unit Thickness (t) — 1 ft
Natural Slope - 15" average slope of natural ground over length of fill area
Fill Slope — 22.5°
Step 1: Area of Fill Wedge (Af)
Af= (%)bh = % * (260 ft.) * (60 ft.)
Af= 7,800 sf
Step 2: Resultant Sliding Force of Fill Wedge (Ff)
Ff = Sliding force of wedge — frictional force (ff)
Ff=Wf*sine -ff
Where, W f = weight of wedge
pf*Af*t
110 pcf * 7,800 sf * 1 ft
858,000 lbs
r- = jL*Wf*Cos *
Ff=Wf*sin e-1L*Wf*cos h
Ff = (858,000 lbs * sin 15°) — (0.2 * 858,000 lbs * cos 15°)
15

0
Ff = 222,000 lbs — 166,000 lbs.
Ff= 56,300 lbs
Step 3: Weight of Boulder Retaining Structure
Slide Force of Fill Wedge = Friction Force on Boulders — Slide Force of Boulders
Ff=µ* WB*cose -WB*sine
or
WB = F f _ (µ * cos e - sine)
WB = 56,300 lbs _ 0 * cos 15' - sin 151)
WB = 176,000 lbs
Step 4: Sectional Area of Boulder Pile Required
As = WB _ PBt
AB = 176,000 lbs + (140 pcf * 1 ft)
AB = 1250 sf
Step 5: Design Dimensions of Boulder Pile
AB = % * (top width + bottom width) * height
*Height at design section (h) = 33 ft and top width = 10 ft
Yields a bottom width = 84 ft
With these dimensions,
AB = % * (10 + 84) * 33
AB=3100sf
• This yields a Safety Factor of (3,100 sf - 1,250 sf) = 2.5
o This design is acceptable
The maximum rock size for the boulder wall will be 4 feet.
