Pilot Project 2732
Dear Mr. Bailey and Ms. Homewood:
Mr. Shawn Cummings of Eastwood @ Angels Glen Homeowners Association Inc. and Agency
Partners LLC received an electronic mail dated April 6, 2018 from the U.S. Army Corps of
Engineers (USACE) and a letter dated April 6, 2018 from the NC Division of Water Resources
(DWR) requesting additional information to process the Nationwide Permit/401 Water Quality
Certification (WQC) application for the Angels Glen Subdivision, located on both sides of Manakel
Drive in Stokesdale, Guilford County, North Carolina. The purpose of this letter is to provide the
USACE and NCDWR the requested information.
USACE Comment 1): "Update plan sheet 1 of 4 to show the existing septic field for phases 1-4, as
well as the new septic field for phase 5. Show how the road that uses the unauthorized stream
crossing accesses these septic fields."
NCDEQ Comment 1): "Please provide a plan sheet that clearly identifies the location of the Phase
4 septic field. [15A NCAC 02H .0506(f) and (g)]"
Applicant Response: The attached plan sheets have been adjusted.

USACE Comment 2): "Please verify that the wetland line shown on the plan sheets is based on
surveyed wetland flags approved by the Corps."
Applicant Response: The surveyors stated that the wetland lines shown on the plan sheets are
based on the surveyed wetland flags approved by the Corps.
NCDWR Comment 2): "In order to ensure downstream water quality protection, please provide
a pond drainage and dam maintenance plan for review. [15A NCAC 02H .0506(f) and (g)]"
Applicant Response: The plans are attached.
USACE Comment 3): "Update all plan sheets to clearly show the wetland line and the pond water
line. Suggestions include removing other similar line styles (e.g. topo lines) and changing the
colors of the wetland and pond lines to contrast with the other features on the plan sheet."
Applicant Response: The attached plan sheets have been adjusted.
NCDWR Comment 3): "Please clarify whether the Division of Energy, Mineral and Land Resources
will require any impacts to wetlands below the dam or adjacent to the road as part of the Erosion
& Sedimentation Control Plan approval. [15A NCAC 02H .0506(f)]"
Applicant Response: All erosion control measures will be outside wetlands or in disturbed
wetlands areas as shown on plans.
USACE Comment 4): "It appears that there will be pond (i.e. open water) impacts related to the
outfall structure to be installed. Even if these impacts are small and/or temporary, please include
them on the plan sheets and in section C.4 of the PCN."
Applicant Response: Impacts are identified on the plans.
NCDWR Comment 4): "Please realign the location of the pond outlet so that it is in better
alignment with the stream channel. [15A NCAC 02H .0506(b)(2)]"
Applicant Response: The attached plans have been adjusted.
USACE Comment 5): "Your PCN states that the pond will be permanently lowered by 1 foot. Since
activities related to installing the new outfall structure require Corps authorization, indirect
impacts to aquatic resources must also be accounted for. As such, will the 1 foot pond drawdown
have any drainage effects on the wetland fringe around the pond. If so, provide the amount of
wetland area to be affected. If not, provide reasoning to that effect."
Applicant Response: Based on our observations of the pond fringe, the slopes along the pond
bank are similar to those that will be created by lowering the water elevation. Based on our

Response to Requestfor Additional Information
Angels Glen Subdivision
June 15, 2018
observations, it is our opinion that there will be no net loss of wetlands. Based on our
observations, a wetland fringe will remain around the pond.
NCDWR Comment 5): "The Division is concerned about secondary and cumulative impacts to the
wetlands immediately downslope of the pond as a result of the proposed renovations to the
pond dam and construction of the road (bisecting one wetland). How would hydrology be
maintained in these wetlands? If these wetland areas cannot be reasonably expected to maintain
their functional quality following pond renovations and road construction then the acreage of
these wetlands should be included as impacts in the 401 application [15A NCAC 02H .0506(f)]."
Applicant Response: Hydrology will not be maintained to these wetlands. The total wetland
impacts in this location have been recalculated to be 7,712 square feet (formerly 5,584 square
feet) to include the wetland that will lose hydrology between the pond and the road crossing. An
updated request has been made to the NC Division of Mitigation Services that includes the
additional impact amount (0.24 Acres). Ms. Kelly Williams with the Division of Mitigation Services
is out of the office until June 22, 2018. Upon receipt, we will provide an updated acceptance
letter from the NC Division of Mitigation Services.
USACE Comment 6): "Sheet 2 of 4 (see attached) appears to show a wetland drainage going
across the dam that would be disturbed, abandoned, or drained once the outfall structure is
installed, water is redirected, and pond level is lowered by 1 foot. Please update the plans to
show this wetland area as being drained. Update the PCN and mitigation proposal accordingly."
Applicant Response: Hydrology will not be maintained to this wetland. An additional 836 square
feet of wetland will be impacted by dropping the water level one foot. An updated request has
been made to the NC Division of Mitigation Services that includes the additional impact (0.24
Acres). Ms. Williams with the Division of Mitigation Services is out of the office until June 22,
2018. Upon receipt, we will provide an updated acceptance letter from the NC Division of
Mitigation Services.
USACE Comment 7): "We are concerned about downstream turbidity and sedimentation impacts
during pond drawdown and outfall structure installation. Please provide your pond
drainage/dam maintenance construction sequence to show how you will protect downstream
areas from sediment/turbidity while you drain the pond."
Applicant Response: Plans call for pumping of the pond to allow for riser and barrel construction.
Rip -rap and stabilization methods are listed in specs for the pond repair (attached).
USACE Comment 8): "Could the 484 sq. ft. of wetland fill be avoided or minimized (per
Nationwide Permit General Conditions 23 (a) and (b)) by changing the curve in the proposed
road? How far must this proposed road be located from the existing pond dam?"

Response to Requestfor Additional Information
Angels Glen Subdivision
June 15, 2018
Applicant Response: The road is situated between a jurisdictional stream and pond dam.
Realigning the road would cause greater impacts to streams and wetlands. The road needs
separation from the pond dam to allow the emergency spillway to function properly and not
impact the integrity of the pond dam.
USACE Comment 9): "How will hydrology be maintained to the wetland down gradient of the 484
sq. ft. of wetland fill such that that area remains a wetland? If hydrology will not be maintained
to this area, include the indirect wetland impacts in the PCN and update your compensatory
mitigation proposal."
Applicant Response: Based on our site observations, the feature that is located between the
pond dam and this wetland is ephemeral. This wetland is located within the flood plain of the
main stream that crosses the site. The wetland originates at the base of a slope that appears to
receive groundwater discharge as well as flood waters from the main stream. Based on our
observations, the pond overflow is merely a secondary source of hydrology for this wetland
during flood events. It is our opinion that this wetland will maintain hydrology and is not likely
to be adversely impacted by the proposed impacts.
USACE Comment 10): "Cross section A -A on sheet 4 of 4 (sewer crossing) shows rip rap placed
above the stream bed, inconsistent with the description of rip rap placement in the PCN. Please
update this cross section for consistency with the description in the PCN."
Applicant Response: The rip rap dissipater will be keyed into the existing elevation of the stream
bed. An updated copy of cross-section on sheet 4 of 4 is included as an attachment.
Based on the above information, it is our opinion that the applicant has fulfilled and provided the
above requested information for the USACE to proceed with Nationwide Permit Verification for
the above referenced project. If there are questions regarding this request, or a need for further
information, please contact us at [phone].

PERMANENT SEEDING SPEC I F I CATI ONS
DEFINITION
5eeding disturbed areas with perennial grassed and/or legumes to provide a permanent vegetative cover
to lessen runoff and soil erosion.
PURPOSE
To lessen soil erosion and permanently stabilize disturbed areas created by grading of construction sites.
CONDITION5 WHERE PRACTICE APPLIES
All bare soil areas on construction sites which are not covered by structures or other erosion control devices.
PREPARATION
Prepare seedbed by ripping, chiseling, hcrrowin?, or plowing to depth of six Inches so as to produce a loose,

*OPERATIONS AND MAINTENANCE PLAN FOR POND SITE*
OWNER- AGENCY PARTNERS LLC
The purpose of this plan is to provide guidelines for carrying out the routine maintenance work
needed to keep this pond operating as planned. Routine maintenance is considered to be normal
good care of the pond. Good maintenance adds to beauty, usefulness, and permanence.
In addition, severe storms will likely call for maintenance, such as replacing and compacting soil
in washes or gullies, reestablishment of vegetation, removal of debris and the like. This type of
maintenance should be done as soon as possible after damage is discovered.
The routine maintenance of this pond involves the following:
1. Maintenance of a vegetative cover on the dam: Fescue is being established on these
areas. Beginning in 2018 and each year thereafter, the dam should be fertilized with
200 pounds of 10-10-10 per acre to maintain a vigorous stand.
2. Removal of logs, brush, or other trash from the entrance of the spillway, and the face
of the dam: This should be done after each rise in the pond surface that deposits such
material. Unless this material is removed, the spillway is likely to become clogged
and the vegetation killed in the affected areas.
3. Control of weeds, brush and trees on the dam: This may be done by mowing, spraying,
or chopping, or a combination of all three. This will need to be done at least once each
year and possibly twice in years favorable to heavy growth of vegetation.
4. Erosion by Wave Action: It is not expected that erosion of the dam by waves will be a
severe problem. However, should such erosion start, lower the level of the pond until
the water surface is about 4 feet below the eroded area. Replace the soil that has been
eroded away, tamp it in place and resod. Fertilize when the new sod takes root and
keep the water surface drawn down.
Maintenance inspections of this pond should be made during the initial spillway repair, at least
annually, and after every major storm. Items to be checked should include, as a minimum, the
following:
1. Pond Drain
a. Damage or obstructions to the spillway.
b. Condition of pipe through dam.
1. Signs of seepage

2. Separation of joints
3. Cracks or breaks
2. Reservoir Area
a. Fallen or cut trees
b. Undesirable vegetative growth
c. Other floating or lodged debris
3. Embankments
a. Settlement, cracking or "jug holes"
b. Side slope stability- slumps or bugles
c. Erosion and/or wave action
d. Rodent damage
e. Seepage or other leakage
f. Condition and type of vegetative cover

Scope of Project
The purpose of this project is to place a pond riser and barrel kit in the pond to prevent erosion
and dam safety issues from water constantly draining through the spillway. We design the riser
and barrel to be placed in the shallowest part of the pond to avoid fully draining the pond and
having to "rebuild" the dam.
The repairs will be done as follows:
First the pond elevation will be lowered to an elevation such that the area for the proposed new
barrel and riser area is dry - Pump pond level down. Schedule work to minimize construction
during rainy/wet periods. Excavate area for new riser pipe and barrel through dam. Compact fill
over and around pipe as required by specifications. Install rip -rap apron at end of 30" RCP. Clear
and grade emergency spillway area again, minimize disturbance of wetlands areas. Seed all
disturbed areas outside of pond normal pool elevation and allow pond to rise to new principal
spillway level.

carbonates. It shall be so graded that 100 percent will pass a No. 10 sieve and
40 percent will bass a No. 100 sieve. During handling and storage, lime shall be
protected against hardening and caking. Any hardened or caked lime shall be
pulverized to its original condition before being used.
4. Mulch shall consist of clean grain straw reasonably free from mature
seed bearing stalks, roots, or bulblets of Johnson Grass, Nutgrass, Sanbur, Wild
Garlic, Wild Onion, Bermuda Grass, Crotalaria, Witchweed, and restricted
noxious weeds as defined by the NC Department of Agriculture at the time of
use. Mulch that is matted or lumpy shall be loosened and separated before
being used.
5. Reuse surface soil stockpiled on the site. Verify suitability of surface soil to
produce topsoil meeting requirements and amend as necessary. Clean topsoil of
roots, plants, sods, stones greater than 1" diameter in all areas to be mowed.
C. Execution
1. The seed bed shall be properly prepared and true to line and grade with lime
and fertilizer worked into the soil 4" to 6" deep. All weeds and other
unacceptable growth shall be cut and disposed of properly. Uneven and rough
areas shall be smoothed to provide a uniform surface. The soil shall be
loosened to a minimum depth of 5" and all clods shall be broken up. The top
2" or 3" of soil shall be worked into an acceptable seedbed by the use of
approved methods. In cut slopes greater than 2:1, the Engineer may permit the
depth of preparation to be reduced, but in all cases the slope surface shall be
scarified, grooved, trenched, or punctured so as to provide places in which
the seeding materials can lodge.
2. Lime and fertilizer shall be distributed uniformly over the prepared seedbed at
the specified rates and then harrowed, raked, or otherwise thoroughly worked
or mixed into the seedbed. Seed shall be distributed uniformly over the
prepared seedbed at the specified rate and immediately harrowed, dragged,
raked, or otherwise worked so as to cover the seed with a layer of soil.
Immediately after seed has been properly covered, the seedbed shall be
compacted by means approved by the Engineer.
3. Within 24 hours after the completion of seeding, all areas shall be mulched.
Mulch shall be spread uniformly by hand or by approved mechanical spreaders
which will provide an acceptable application. An acceptable application will be
that which will allow some sunlight to penetrate and air to circulate but also

partially shade the ground, reduce erosion, and conserve soil moisture.
4. Mulch shall be held in place by applying a sufficient amount of asphalt
emulsion or other approved binding material. The rate and method of
application shall meet the approval of the Engineer. When the binding material
is not applied directly with the mulch, it shall be applied immediately following
the mulch application. During the application of the binding material, adequate
precautions shall be taken to prevent damage to traffic, structures, traffic
control devices, and other appurtenances. When any damage does occur, the
Contractor shall repair it, including any necessary cleaning. The Contractor
shall take precautions to prevent mulch from entering drainage
structures and shall promptly remove any blockages which may occur.
Unless specified otherwise in the SPECIAL CONDITIONS, the type of seed
and the rates for seed, fertilizer, lime and mulch shall be as listed below:

D. Execution
1. Loosen subgrade to a minimum depth of 6 inches. Remove stones larger than 1
inch in any dimension and sticks, roots, rubbish, and other extraneous materials.
Remove excess gravel, which will inhibit the growth of vegetation.
2. Grade lawn and grassed areas to a smooth, even surface with loose, uniformly fine
texture. Roll and rake, remove ridges, and fill depressions to meet finished grades.
Limit fine grading to areas that can be planted in the immediate future. Remove
trash, debris, stones larger than 1 inch in any dimension (1/2 inch in playing fields),
and any other objects that may interfere with planting or maintenance operations.
Remove all glass, wire or other objects of any size that may cause future injuries.
3. Sow seed with a spreader or a seeding machine. Do not broadcast or drop seed
when wind velocity exceeds 5.0 MPH. Evenly spread seed by sowing equal
quantities in two (2) directions at right angles to each other.
4. Sow seed at the rates required to achieve 95% coverage prior to completion as
determined on a per square yard basis.
5. Rake seed lightly into top 1/8 inch of topsoil, roll lightly, and water with fine spray.
Remove surface rocks of greater than 1 inch for lawns and'/2 inch for playing
fields.
6. Protect seeded areas against erosion by spreading straw mulch immediately after
seeding operation is complete. Spread straw mulch at a minimum rate of 3000 lbs.
per acre to create a continuous blanket 1 tot -1/2 inches loose depth over seeded
areas.
7. Install erosion control matting on slopes and in drainage swales as indicated on the
approved erosion control plan. The matting shall be the type of grade as specified
on the erosion control plan (or approved equal), and according to manufacture's
recommendations.
8. Consult Conservation Inspector on maintenance treatment and fertilization after
permanent cover is established.

Apply: Agricultural Limestone- 2 tons/acre or 3 tons/acre in clay soils.
Fertilizer -
1000 lbs/acre (10-10-10).
Superphosphate- 500 lbs./acre (20%)
Mulch- 2 tons/acre (small grain straw)
Consult Conservation Engineer or Soil Conservation Service for additional
information concerning other alternative for vegetation of denuded areas. The
above vegetation rates are those which do well under local conditions, other
seeding rate combinations are possible.
9. The Contractor shall maintain seeded areas in a satisfactory condition until final
acceptance of the project. Areas of damage or failure due to any cause shall be
corrected by being repaired or by being completely redone as may be directed by
the Engineer. Damage or failure resulting from poor seed, the Contractors
operation, or his failure to provide erosion control shall be repaired or
replaced at the Contractor's expense.
10. The Contractor shall maintain adequate drainage on the project at all times. In the
event water pockets are formed, they shall be drained by the Contractor and all
wet and unstable material shall be removed and disposed of and the area
backfilled and compacted with suitable material. Such remedial work caused by
the failure of the Contractor to keep the area adequately drained shall be
performed at his expense.
