D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The construction access route was located in the field to avoid as much as possible the existing trees and will be replanted. The construction limits
have been minimized to extend to the areas of work for the breach opening and fill areas. A channel will be established in the existing pond to
promote a healthy re-establishment of the stream profile through the pond and the entire pond will be stabilized in accordance with the stabilization
plan. Sediment will not be discharged downstream
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The excess soil removed from the dam will be kept on site and used to transition the pond banks in the northeast and northwest corners placing fill
outside of wooded areas. The existing degraded spillway channel in the north east corner of the site is planned to be filled to existing contours and the
replanted for long term stability_ De -watering activities have been designed to minimize sediment and erosion into the buffers. Erosion control
measures have been established for the site

Pre -Construction Notification (PCN) Form Supplement Data
Underwood Dam Breach, Raleigh, North Carolina
B. Proiect Information and Prior Project History
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project
at the time of this application:
The project dam is located in the Crosstowne subdivision in Raleigh, NC. The dam is listed under the
name of Underwood Dam with the state of North Carolina Dam Safety program registry, has an
inventory number of WAKE -236-H, and is listed as high hazard. The dam forms an impoundment with an
approximate area of 3.1 acres. The NC Dam Safety Inventory dated July 16, 2018 lists the existing
condition of the dam embankment as poor. The date of dam construction is unknown.
The dam is primarily earthen with a block retaining wall structure on the downstream face of the dam,
approximately 40 feet in length, located in the center of the structure. The principal outlet pipe a 10 -
inch Steel/Ductile Iron that shows signs of corrosion and an 8 -inch DIP drain pipe penetrate the retaining
wall. The riser for the outlet pipe is submerged and is presumed to be partially clogged and broken. A
small amount of water was observed exiting the pipe. Due to the minimal flow entering the principal
outlet pipe a channel has formed on the west side of the pond and serves as the primary outflow. A
large head cut is located is located approximately 180 feet downstream of the pond on this channel. The
head cut is approximately 8 feet in elevation. The stream origin for the jurisdictional stream along this
flow path called UT -2 to Walnut Creek on the impact map, has been determined at the bottom of the
head cut. This jurisdictional stream combines with the jurisdictional stream that is located below the
retaining wall structure called UT -1 to Walnut Creek at the principal pipe discharge location. The
tributaries below the dam structure do not have a FEMA regulated floodplain or floodway.
3d. Explain the purpose of the proposed project:
Habitat for Humanity is developing this property, single family residential, and the expense of upgrading
and continued maintenance for the dam is beyond the means of the HOA and therefore a dam breach
plan has been submitted to the State of NC Dam Safety Office for approval. The HOA will let this area re -
vegetate and re-establish as a riverine system. The area will remain in a natural condition. No other uses
are planned for this area.
3e. Describe the overall project in detail, including the type of equipment to be used:
The project will consist of an access corridor to get construction equipment to the dam breach site to
excavate and waste existing materials to provide a breach opening that will pass the 1/3 PMP storm
event required by the NC State Dam Safety office. The entrance corridor has been field located to
minimize removal of trees. The project will first require dewatering of the existing pond. The dewatering
intake will be from the surface of the pond as required by Dam Safety. The dewatering outlet will
discharge onto a rock pad to dissipate energy and minimize any erosion. Upon completion of dewatering
the principal outlet barrel will be used to convey daily water flows through the dam. The demolition of
the dam and embankment will work from the top down mainlining the bypass flow through the principal
outlet pipe as long as possible. A bypass pump will be set when the excavation gets to elevations
requiring the existing pipe to be removed. The soils will be wasted on site in the northeast and
northwest corners of the pond. The breach opening is planned to be 31 feet at the bottom with 3H:1V
Ward Consulting Engineers, PC Underwood Dam Breach

side slopes. The toe of the slope for a vertical distance of 2 feet as well as the bottom of the opening is
planned to be stabilized with riprap. A channel is planned to be excavated upstream of the opening
through deposited sediment to minimize existing soil losses downstream and maintain the existing
stream slope. The channel will be stabilized with seed and matting. Riparian seed and mulch is planned
to stabilize the pond area under the current water level.
It is anticipated that earth moving equipment will be used for the project including but not limited to
excavators, loaders, and dump trucks.
C. Proposed Impacts Inventory
4. Open Water Impacts
No open water impacts requiring a permit from the COE are proposed for this project. The breach of the
dam will cause a permanent loss of the upstream impoundment. Through the construction operations
planned no dredged or fill material will be discharged into the downstream jurisdictional stream. A
stream corridor will be excavated through the upstream sediment behind the dam to tie into the natural
upstream channel. The channel banks will be stabilized with matting and vegetation. Fill slopes behind
the dam will be stabilized with seed and matting. The exposed floodplain will be seeded and mulched.
An erosion control plan has been established for the construction of the project which includes
dewatering from the top of the pond and discharge of the dewatering outlet to a stable rock pad
location to dissipate erosive velocities.
6. Buffer Impacts
The impacts have been associated two streams UT -1 to Walnut Creek and UT -2 to Walnut Creek and the
existing pond buffers. The impacts are described as follows:
• UT -2 Walnut Creek: The impacts on UT -2 will occur in Zones 1 and two and will be for temporary
construction access. The area will be reseeded and planted at the end of the project.
(131) Zone 1: 897 sf Zone 2: 784 + 806=1590 sf
• UT -1 Walnut Creek: The impacts on UT -1 consist of both temporary and permanent impacts. The
temporary impacts are areas that will be used for construction access and the breach opening
cut area. The permanent impacts will be the riprap established in the breach opening to
maintain long term stability during the 1/3 Probable Maximum Precipitation (PMP) storm event.
(132) Temporary Impacts Zone 1=1,851 sf Zone 2= 1,902 sf
(134) Permanent Impacts Zone 1=1,089 sf
• Existing Pond Buffers: The existing pond is planned to be permanently drained as a part of the
dam breach plan. Therefore the Pond buffers disturbed due to construction access within the
Limits of disturbance will no longer be pond buffers so we have shown them to a permanent
impact, however this area will be revegetated. The existing pond valley will be reseeded with
riparian seed and left to naturalize. A stream channel will reestablish through the existing pond
basin. This project is only to remove the high hazard dam risk from the HOA. No future
development is planned for this area.
Existing pond buffer impacted by construction: (133) Zone 1: 2,301 sf Zone 2: 2,714 sf

Re: Underwood Pond Dam Environmental Investigation 18-005
Summary Letter
Wake County, NC
Dear Becky:
This letter provides a summary of the results of an Axiom Environmental, Inc. (Axiom) investigation
at the above-mentioned study area (Figure 1). The approximately 12.12 -acre study area is located
around Underwood Pond east of the Crosstowne subdivision and west of Upper Room Christian
Academy on Idlewild Village Drive in Raleigh, NC. The study area includes Underwood Pond, the
Underwood Pond dam, reaches of stream above the pond and below the dam, a Crosstowne
subdivision stormwater basin, and mesic pine/mixed hardwood forest.
Axiom biologists conducted a field visit on March 28, 2018. As part of the investigation, we
accomplished the following tasks within the study area: a general environmental investigation, a
Section 404 jurisdictional area delineation, a riparian buffer determination, and a federally protected
species survey. Forms documenting our findings are attached to this summary letter. The results of
the jurisdictional area delineation are depicted on Figure 1.
General Environmental Features
The majority of the study area supports a mesic pine/mixed hardwood forest characterized by a
mature, closed canopy, a well-developed sub -canopy, and sparse shrub and herb components. The
canopy is composed of loblolly pine (Pinus taeda), red maple (Acer rubrum), yellow poplar
(Liriodendron tulipifera), black willow (Salix nigra), and, sweetgum (Liquidambar styraciflua).
Sub -canopy species include flowering dogwood (Cornus florida), black gum (Nyssa sylvatica) tag
alder (Alnus serrulata), and sourwood (Oxydendron arboreum). Shrubs are limited to saplings of
canopy species, Chinese privet (Ligustrum sinense), and Russian olive (Elaeagnus angustifolia).
Herbs and vines include Japanese stilt -grass (Microstegium vimineum), spotted touch-me-not
(Impatiens capensis), muscadine (Muscadinia rotundifolia), poison ivy (Toxicodendron radicans),
Japanese honeysuckle (Lonicera japonica), and common greenbriar (Smilax rotundifolia).

Section 404 Jurisdictional Area Delineation Results
Open Water
Underwood Pond is the one jurisdictional open water within the study area. The stormwater basin in
the northwest portion of the study area is not a jurisdictional feature. The boundaries of the open
waters of Underwood Pond were located with GPS technology and refined with Quality Level 2
(QL2) Light Distance and Ranging (LiDAR) data.
Streams
Four jurisdictional streams were identified within the study area.
• A perennial unnamed tributary to Walnut Creek, designated Stream SA, that flows toward the
head of the pond and away from the pond below the dam. The lower end of the reach of
Stream SA above the pond is located where stream features (bed and bank, sediment sorting)
cease being apparent and hydrology is transitioned to a jurisdictional wetland area (Wetland
WA). The outflow pipe through the dam appears to be partially blocked, reducing the
amount of water flowing from the pond into Stream SA below the dam.
• The dam outflow pipe blockage causes water to flow more regularly through the overflow
channel west of the dam, resulting in an intermittent stream (Stream SB) that flows into
another intermittent stream (Stream SC). The flashy flow of Stream SB has caused the
formation of a head cut that is working its way up the overflow channel path to the dam.
• A man-made drainage ditch, intermittent Stream SC, transports water from the stormwater
basin to Stream SA below the dam. The lower portion of Stream SC is deeply incised as a
result of the headcut that has migrated up lower Stream SC into Stream SB.
• Perennial Stream SD drains a residential neighborhood east of the dam into Stream SA just
below the dam.
These streams were marked in the field with enumerated solid blue and solid orange flagging.
Evaluations using N.C. Division of Water Resources (NCDWR) guidance (the NCDWQ Stream
Identification Form, Version 4.11) were used to determine the intermittent/perennial character of
these streams and are attached to this summary letter. N.C. Stream Assessment Method (NC SAM)
evaluations for these streams are also attached.
Wetlands
Five jurisdictional wetlands were identified within the study area; all of which appear to be the result
of anthropomorphic disturbances. The wetlands are listed below by type.

Axiom Environmental, Inc.
Ms. Becky Ward
April 3, 2018
Page 3
• Wetlands WA and WF are Riverine Swamp Forests on the fringe of the pond. Wetland WA
is at the upper end of the pond and receives wetland hydrology from Stream SA and the
pond. Wetland WF is along the eastern side of the pond and receives wetland hydrology
from stormwater runoff from an adjacent school and the pond.
• Wetlands WD and WE are Floodplain Pools. Wetland WD is a splash pool in the emergency
spillway below the east end of the dam. Wetland WE appears to be an abandoned stream
reach below the west end of the dam. Both Wetlands WD and WE may be considered
"isolated" by the U.S. Army Corps of Engineers (USACE); however, their proximities to
Streams SA and SD make this determination uncertain without USACE consultation.
• Wetland WC is a small length of Bottomland Hardwood Forest adjacent to lower Stream SA,
likely resulting from past scouring of storm overflows from Stream SB.
Wetland boundaries were marked in the field with enumerated solid blue and pink -and -black striped
flagging. Wetland boundaries were identified using the 1987 Corps of Engineers Wetland
Delineation Manual and the USACE Regional Supplement to the 1987 Manual (Eastern Piedmont
and Mountains). Wetland characteristics were documented using the USACE Regional Supplement
to the 1987 Manual (Eastern Piedmont and Mountains) Data Form, which are attached to this
summary letter. N.C. Wetland Assessment Method (NC WAM) evaluations for these streams are
also attached.
Riparian Buffers
Any surface water depicted on either the most recent version of the NRCS county soil survey or the
most recent version of the USGS 7.5 -minute quadrangle is subject to the Neuse River riparian buffer
rules (15A NCAC 02b.0233). Underwood Pond, the primary drainage (Stream SA) to Underwood
Pond, Stream SC, and Stream SD are subject to the buffer rules. The buffer extends 50 feet
perpendicular to the pond shoreline and from each bank of the streams (see attached Figure 1).
The drainage (dewatering) of a pond in a natural drainage way is exempt from the buffer rule
provided that a new riparian buffer that meets the requirements of the rule (specifically a 30 -foot
wide Zone 1 and a 20 -foot wide Zone 2 and the diffuse flow of runoff) is established adjacent to the
new channel.
Federally Protected Species
Based on the most recently updated county -by -county database of federally listed species in North
Carolina as posted by the U.S. Fish and Wildlife Service (USFWS) (accessed March 27, 2018), the
bald eagle and five federally protected species are listed for Wake County. Table l lists these species
and indicates if potential habitat exists within the study area.

*Federal Status: BGPA=Protected by the Bald and Golden Eagle Protection Act, E=Endangered
Bald Eagle
Underwood Pond provides low -quality feeding habitat, and the pond shoreline supports scattered
large trees that could be used for eagle roosting. The N.C. Natural Heritage Program (NCNHP) has
no documentation of bald eagle within 1.0 mile of the study area, and no eagles were observed
during the visit. The proposed project May Affect but is Not Likely to Adversely Affect bald
eagle.
Cape Fear Shiner
Study area water resources are not within the upper Cape Fear River basin. The NCNHP has no
documented occurrences of Cape Fear shiner within 1.0 mile of the study area. The proposed project
will have No Effect on the Cape Fear Shiner.
Red -cockaded Woodpecker
The study area supports loblolly pines, greater than 60 years old, along the dam and pond shoreline.
This is considered suitable nesting and foraging habitat for red -cockaded woodpeckers. The only
other suitable habitat for red -cockaded woodpeckers within 0.5 mile of the study area is a stand of
pines just west of the Crosstowne subdivision. An investigation of these trees found no evidence of
red -cockaded woodpecker nesting/roosting. The NCNHP has no documented occurrences of red -
cockaded woodpecker within 1.0 mile of the study area. The proposed project will have No Effect
on red -cockaded woodpecker.

Dwarf Wedgemussel
Habitat for dwarf wedgemussel consists of slow, well -oxygenated creeks and rivers with sand,
gravel, or firm silt bottoms. Study area streams are small and characterized by excessive
sedimentation, providing no suitable habitat for this species. No mussel shells were observed during
field investigations. The NCNHP has no documentation of dwarf wedgemussel within 1.0 mile of
the study area. Suitable habitat for dwarf wedgemussel does not occur within or adjacent to the
study area; therefore, the proposed project will have No Effect on dwarf wedgemussel.
Michaux's Sumac
Suitable habitat for Michaux's sumac is lacking within the study area due to the presence of acidic
soils. No evidence of this species was found during our field investigations. The NCNHP has no
documentation of Michaux's sumac within 1.0 mile of the study area; therefore, the proposed project
will have No Effect on Michaux's sumac.
Response to issues noted on the site map provided to Axiom:
• Overflow channel on west side of dam — The overflow channel (Stream SB) is a man-made,
intermittent channel excavated in uplands of an outer floodplain slope. We think resource
agencies will be amenable to not requiring mitigation for the loss of this channel. Stream SB
is a logical place to bury dam debris.
• Access between houses — This issue is out of Axiom's area of expertise.
• Emergency spillway — The emergency spillway contains only one, small wetland (Wetland
WE). The USACE may consider this feature "isolated" and not subject to Section 404
jurisdiction.
• Concrete debris disposal — Dewatering a pond in a natural drainage way is exempt from the
riparian buffer rule provided that a new riparian buffer that meets the requirements of the rule
(specifically a 30 -foot wide Zone 1 and a 20 -foot wide Zone 2 and the diffuse flow of runoff)
is established adjacent to the new channel. The new buffer will extend outward from the
banks of the restored stream under what is now the pond and dam. The northwest corner of
the existing dam will likely be outside of the riparian buffer established on a stream within
the pond footprint following dam removal and may therefore be a good candidate site for the
burial of dam debris.
