Hi Bob!
The Max Crowe pond and dam project # 011749 is ready to issue. I
discussed this project with Mike last week, then talked to Steve Chapin
today.
I gave a copy of the staff report to Mike for his approval, but he just
said "whatever you want to do!".
We gave him a tube of Balmex (diaper rash ointment) in the staff meeting
this morning. Guess we'll have to try Gold Bond next. He's still in a
BAD mood. I think he's STRESSED OUT from his new job!!!
I'll keep y'all posted!

The project consists of constructing a small pond by culverting 140 feet of Wheat Creek , a small (,?
feet wide) perenial stream in Polk County. The pond's dam will be approximately 25 feet in height
and create a onding area of 1300 linear feet to produce 6.5 acres (65 acre-feet) of pond.
The total impact will be 1440 linear feet (140 culvert and 1300 onding) with no impact to wetlands.
I spoke with Steve Chapin- USACOE_ who visited the site and determined there were no wetland
impacts. His comments from Wildlife were favorable and both recommend issuance.

Project Description
The purpose of this project is to construct a small pond along the eastern edge of Polk
County, North Carolina. The dam is of sufficient size to require permitting by the state,
and will be classified as a low hazard class, small dam.
The elevations shown on the drawing are based on an assumed datum and do not reflect
the true elevation above sea level. Based on the assumed datum, the spillway discharges
the flow at an elevation of 414 feet with a top of dam elevation of 439 feet thus resulting
in an effective dam height of 25 feet. The top of water elevation will be 436 feet
resulting in a total pond area of approximately six and one-half (6.50) acres. Assuming
the average depth of the pond is equal to 40% of the dam height (i.e., 10 feet), the pond
size in acre-feet would be 65.0 acre-feet.
Regarding the actual design of the dam, the upstream embankment will be a 2:1 slope and
the downstream embankment will have a 3:1 slope for ease of maintenance. The
emergency spillway is a 50-foot wide channel placed in the crest of the dam and is 1.0
feet deep. The channel will be lined with rip rap placed on top of filter fabric to prevent
erosion should the emergency spillway be utilized.
Soils
Soil studies will be performed on-site by the engineer at the time of excavation.
Supportine Calculations
The following calculations were performed using both a spreadsheet designed to
calculate storm flows as well as the program "Hydroflow Hydrographs". The
spreadsheet was designed to calculate the storm flows based on the SCS method of
floodwater runoff. The values obtained from the spreadsheet were then used in the
Hydroflow program to design the spillways size(s). Included in this section is a copy of
the spreadsheet output as well as four graphs from the Hydroflow program displaying the
hydrograph of the routed and non-routed storm flows, water surface elevation vs. time,
and discharge capability vs. water elevation. Based on the derived information, the 50-
year storm event can be carried in the emergency spillway comprised of a 50-foot, wide
trench 1.0 feet deep lined with rip rap. Lastly, a spreadsheet was created to calculate the
necessary weight required to offset the buoyancy of the standpipe. The above
information is located on the following pages.

Storm Flow Calculation Utilizing the SCS Peak Discharge Method
Polk County, North Carolina
This document calculates the flow for a 50-year, 24-hour storm event in Polk County, North Carolina, using the SCS method.
The area in question is comprised of approximately 178.63 acres of land with a soil classification of B. The hydraulic length
(maximum length of water flow) is approximately 2500 feet with an average slope of 3.8%. The land in this area has the
following characteristics:.
Type Description of Terrain % of Total CN Value
Type I Wooded 100% 55
Type II None Listed N/A N/A
Type III None Listed N/A N/A
Type IV None Listed N/A N/A
Type V None Listed N/A N/A
In addition to the above information, data must be extracted from tables that can be found in the 'Erosion and Sediment
Control Planning and Design Manual' published by the North Carolina Department of Environment and Natural Resources.
All references in the equations below refer to this manual.
Based on the soil and land types listed above, the CN can now be calculated. Based on the given information as well as
chosen CN values from Table 8.03b, page 8.03.10 in the reference, the final CN value is calculated to be:
Type Description of Terrain % of Total CN Value % Total x CN Value
TypeI Wooded 100% 55 55
Type II None Listed N/A N/A N/A Please Note: The column "% Total x CN
Type III None Listed N/A N/A N/A Value" is summed to give the Final CN
Type IV None Listed N/A N/A N/A Value
Type V None Listed N/A N/A N/A
Final CN Value >>> 55
Based on the area in question (Polk County, North Carolina), the rainfall amount during a 50-year, 24-hour storm is 8 inches
(Reference, Figure 8.03). In addition, the average runoff depth is 2.9 inches (Reference, Page 8.03.17, Table 8.03c).
Lastly, the equivalent drainage area based on the hydraulic length of 2500 feet is 65 acres (Reference, Page 8.03.18, Figure
8.03p).
Determining Q
We first determine our peak discharge (33 CFS/Inch) using Table 8.03p, and multiply it by our runoff depth of 2.9 inches to
get our initial flow.
Q, = 33 CFS/Inch x 2.9 inches = 95.7 CFS
The following equation takes into account the equivalent acreage vs. the actual acreage based on the hydraulic length.
Q2 = 95.7 CFS x (178.63acres/65acres) = 263 CFS
We will next use the impervious factor of 1 (Reference, Page 8.03.21, Figure 8.03r) to modify the flow.
Q3 = 263 CFS x 1
= 263 CFS
To adjust for the watershed slope, we will use a slope adjustment factor of 0.9 (Reference, Page 8.03.23, Table 8.03d)
Q4 = 263 CFS x 0.9 = 236.7 CFS
Lastly, we must adjust for any ponding effects impacting our flow with an adjustment factor of 1 (Reference, Page 8.03.24,
Table 8.03e)
Q = 236.7 CFS x 1 = 236.7 CFS
Summary
Based on the above equations and adjustment factors found in the reference, the flow for a 50-year, 24-hour storm event in
this particular area of Polk County, North Carolina, would be 236.7 CFS.
Figure 4: 50-Year Storm Event Hydroaraph
The following hydrograph displays the discharge (in cubic feet per second) due to a 50-
year storm event. The information used to plot this hydrograph was derived in the
Hydroflow program. Since the peak flow value was roughly the same using the
Hydroflow program (233.86 cfs vs. 236.7 cfs), this value was used in all additional
calculations.

Anti-Flotation Calculations
The following information is a calculation to determine the necessary area and weight required to offset the
buoyancy force of the standpipe in dam construction. The exact displacement is calculated and then a safety
factor is used to determine the final weight and concrete volume required. These calculations are based on the
average value of concrete density of 150 pcf.
In this scenario, the standpipe diameter is 18 inches with a total length of 20 feet. Below is the calculation of
the displaced water volume, weight of the water in pounds, and the cubic yards of concrete required to offset
this buoyancy force.
Displaced Water Volume
V = (pi)(r2)(1) _
Weight of Displaced Water
W = (V)(density) =
Required Volume of Concrete
V = (weight)1(density)(27 cf/cy) =
[pi][0.75 ft][0.75 ft][20 ft] = 35.3 cubic feet
[35.3 ct](62.4 pct] = 2205.4 pounds
[2205.4 lbs]/(150 pct][27 cf/cy] = 0.5445 cubic yards
Now that we have the exact figure to offset the buoyancy force, we can now apply the chosen safety factor of
1.25 to determine the volume of concrete required.
V = (initial volume)(safety factor) = [0.5445 cy][1.25] = 0.6807 cubic yards

SMALL DAM CONSTRUCTION SPECIFICATIONS
1. SITE PREPARATION
The site shall be shaped and prepared prior to the placement of earth fill. Once the clearing and
grubbing limits have been identified, all trees, stumps, logs, snags, shrubs, rubbish, and debris shall
be removed. Trees shall be cut as near to the ground as conventional equipment will permit. All
stumps and roots having a diameter of one inch or greater shall be grubbed out to a depth of one
foot below the ground surface. Any fences encountered within the grubbing limits shall be
removed as part of the clearing and grubbing operation. All material removed as part of the
clearing and grubbing operation shall be burned. All disposal of material by burning shall be in
strict accordance with applicable state law and local ordinance.
All channel banks and steep areas within the foundation area of the dam shall be shaped to a slope
of 1:1 or flatter. The foundation shall be stripped of topsoil and undesirable material. After
stripping, the foundation area shall be prepared to assure proper bond with the fill material by
removing loose dry material, scarifying, disking, adjusting the moisture, and compacting the
foundation material as necessary, prior to the placement of the fill material.
2. EXCAVATION
The cutoff trench shall be excavated to remove and sand, gravel, and other permeable material.
The actual depth of the cutoff trench shall be determined in the field by the engineer to ensure all
unsatisfactory material is removed. Suitable materials obtained from the required excavations may
be used in the embankment. Unsuitable material shall be disposed of in an area designated by the
engineer.
3. EARTH FILL
All fill material shall be free from sod, brush, roots, frozen soil, rocks over 6 inches in diameter and
other objectionable material. The distribution and gradation of materials shall be such that there
will be no lenses, pockets, streaks, or layers of material differing substantially in texture or
gradation. The more plastic and impervious material shall be placed in the center portions of the
fill. Fill shall not be placed until the foundation area is free of standing water and is properly
grubbed, shaped, and scarified. The moisture content of the fill material shall be such that the fill
can be satisfactorily compacted and shall be within plus or minus 3% of optimum. Optimum
moisture shall be as defined by ASTM D 698, Method A. The placing and spreading of fill shall be
started at the lowest point of the foundation and shall be brought up in approximately horizontal
layers. The maximum thickness of a layer before compaction shall be 8 inches. The entire surface
of each layer shall be compacted by at least three passes of a standard tamping roller. Fill placed
within two feet of the pipe or any structure shall be placed in layers not to exceed four inches thick
and compacted to a density equivalent to that of the surrounding fill by means of hand tampering or
manually directed power tampers. Heavy equipment shall not be operated within two feet of any
structure.

4. PIPE SPILLWAY
The spillway barrel and riser pipe will be 14 gauge CMP and 12 gauge CMP,
respectively.
Fabrication and installation of the pipe spillway shall be as specified on the
drawings and as required by specification. The pipe conduit shall be placed on a
firm foundation to the lines and grades shown on the plans. Installation shall be
performed in a skillful and workmanlike manner in accordance with the
manufacturer0s recommendations. Prior to laying the pipe, a foundation trench
shall be prepared for the pipe by filling approximately two inches above grade'with
compacted material. The foundation area for the pipe shall then be excavated to
approximately 1 inch below the planned invert elevation for the pipe and shaped to
conform to the outside diameter of the pipe. One inch of select impervious moist
material shall be placed in the shaped foundation trench immediately prior to
placing the pipe.
The pipe shall then be placed to line and grade and firmly and uniformly bedded in
the foundation trench throughout its entire length with select impervious moist fill
material. The area supporting the joints shall be over excavated as necessary to
allow for assembly and to ensure that the pipe barrel is uniformly supported by the
soil bedding. Select moist backfill material shall be placed and hand compacted
around the pipe conduit at approximately the same rate on both sides of the pipe.
Compaction around the bottom half of the pipe must be firm to fill all voids, but
extreme caution must be exercised to prevent damage, movement, uplift or
deflection of the pipe.
5. DRAIN FILL- N/A
6. DRAIN PIPE- N/A
7. SEEDING-
Subsoil shall be prepared to eliminate uneven areas and low spots. Lines, levels,
profiles and contours must be maintained. Make changes in grade gradual and bend
slopes into level areas. Remove foreign materials, weeds and undesirable plants
and their roots and remove any contaminated sub-soil. Scarify subsoil to a depth of
3 inches where topsoil is to be places. Repeat cultivation in areas where equipment
used for hauling and spreading topsoil has compacted the sub-soil.
Spread topsoil to a minimum depth of 8 inches over area to be seeded and rake until

Pre-Construction Notification (PCN) Application Form
For Section 404 and/or Section 10 Nationwide, Regional and General Permits, Section 401
General Water Quality Certifications, and Riparian Buffer and Watershed Buffer Rules
This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's
(DWQ) associated General 401 Water Quality Certifications. This form is also to be used for any
project requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water
Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Permit application form is available online at
http://www.saw.usace.army.mil/wetlands/Perm app htm.
The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://www.saw.usace,army.mil/wetiands/re2tour.htm, or contact one of the field
offices listed at the end of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.
The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.nc.us/ncwettands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for some General Certifications is not required,
provided that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet
should contact DWQ's Central Office in Raleigh at [phone].
Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is also required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on the last page of this application).
Page 1 of 12
CAMA Coordination - If the project occurs in any of North Carolina's twenty coastal counties (listed on
the last page of this application) the applicant should also contact the North Carolina Division of Coastal
Management (DCM) at [phone]. DCM will determine whether or not the project involves a
designated Area of Environmental Concern, in which case DCM will act as the lead permitting agency.
In such cases, DCM will require a Coastal Area Management Act (CAMA) Permit and will coordinate
the 404/401 Permits.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office (addresses are listed at the end of this
application). Upon receipt of an application, the USACE will determine if the application is complete as
soon as possible, not to exceed 30 days. This PCN form is designed for the convenience of the applicant
to address information needs for all USACE Nationwide, Regional or General permits, as well as
information required for State authorizations, certifications, and coordination. Fully providing the
information requested on this form will result in a complete application for any of the USACE
Nationwide, Regional or General permits. To review the minimum amount of information that must be
provided for a complete PCN for each USACE Nationwide permit, see Condition 13, 65 Fed.Reg. 12893
(March 9, 2000), available at http://www.saw.usace.army.mil/wetlands/nnfinalFedReg_pdf.
Processing times vary by permit and begin once the application has been determined to be complete.
Please contact the appropriate regulatory field office for specific answers to permit processing periods.
401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 401/Wetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ website at http://h2o.ehnr.state.nc.us/ncwetlands/fees.html. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
requested information, or denial.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration

NARRATIVE
PROJECT DESCRIPTION
The purpose of the project is to construct a dam on the eastern edge of Polk County.
Approximately 6 acres will be disturbed during this construction period.
SITE DESCRIPTION
The site is 24.55 acres located on the eastern edge of Polk County.
ADJACENT PROPERTY
Land use in the immediate vicinity is rural/residential.
SOILS
The soils in the project area are determined to be classified as Soil Group C utilizing the table on
page 8.03.8 of the reference. According to a U.S. Department of Agriculture Soil Conservation
Service survey of the area, most of the topsoil is clayey loam.
MAINTENANCE RESPONSIBILITY
The owner is responsible for ensuring compliance with temporary measures and for instituting
permanent measures.
SUPPORTING CALCULATIONS
1. RUNOFF
Runoff was determined using the Rational Method as explained in the manual. We determined the acreage
contributing runoff using the Quadrangle Map. The value for the Runoff Coefficient (C) was
taken from Table 8.03a in the manual. The land surrounding the dam construction is wooded and has a C
value of 0.20. A return period of 25 years and the rainfall intensity duration
curve for Asheville was used in the design. The governing equation is Q=C"I'A. Data for calculations is below:
C AREA ac I in/hr Q cfs
TSP #1 0.4 0.6 7.2 1.7
TSP #2 0.4 0.16 7.2 0.5
TSP #3 0.4 0.15 7.2 0.4

TSP #9 0.4 0.39 7.2 1.1
TSP #10 0.4 0.39 7.2 1.1
IV. SEDIMENT TRAPS
There will be five temporary sediment traps utilized on the project. In accordance with Section 6.60 of the
reference, the temporary sediment traps are to be used below disturbed areas where the total drainage area is
less than 5 acres. They are sized for a volume of 1800 ft3/acre based on the disturbed area draining into the
basin. Weir lengths are based on drainage area. All traps will have an effective depth of 2'. For improved
efficiencies, larger surface areas are used with the following equation as guidance:
