3 Pro�ect Description
3a Descnbe the existing conditions on the site and the general land use in the vicmity of the proJect at the time of this
application
On the east bank of the Reddies River lies the raw water intake and raw water impoundment operated by the Town of
North Wdkesboro The raw water impoundment is behind an ex�sting dam on the Reddies R�ver with two sluice gate
operated bypass flumes(one on each side of the dam) raw water mtake and raw water pump station (on the east bank
as well ) To the west and south of the proposed work site is the Reddies River with the existing dam To the north and
east of the intake location is the Yadkin River Greenway and beyond that undeveloped woodland
3b List the total estimated acreage of all existing wetlands on the property
Other than the Reddies nver the National Wetlands Inventory Mapper lists no other wetlands on the property
3c List the total estimated linear feet of all existing streams(mtermittent and perenrnal)on the property
+/ 4300 If Reddies River +/ 400 If total other intermittent or perenrnal streams
3d Explain the purpose of the proposed pro�ect
Due to severe siltation behmd the dam the raw water mtake can from time to time become clogged severely hindering
the inflow of raw water into the Town of North Wdkesboro s intake structure The sdtation fills up the aproach to the intake
such that raw water does not flow into th eintake To alleviate this problem the JTown must open the slwce gate on the
side of the impoundment closest to the intake and flush the silt away from the intake approach This flushmg has caused
problems downstream of the dam Those problems include reduce disolved oxygen in the river and poor taste and odor
of the water
The embankment between the intake and the sluice gate wdl be armored with a 50 5 long cast in place concrete retairnng
wall to protect it from further erosion This is the recommended approach presented in a previously prepared Preliminary
Engineering Report studying the stltation problem (included in supportmg documents see section 6 3)
Construction of the wall is considered part of maintenance to the impoundment and mtake
3e Describe the overall pro�ect in detad including the type of equipment to be used
Retaining wall is to be constructed from the east bank of the Reddies River between the existing intake structure and the
bypass Coffer dams are to be constructed at the per�meter of the work area within the Redd�es River and intenor water
pumped out of the work area through sdt bags to prevent dispersal of sediment out of the work area Micropde foundation
is to be constructed according to plans and cast in place concrete wall to be constructed on the micropiles Micropiles are
less mvasive and disturb less area than other foundation systems such as spread footings Micropdes are desireable for
construction in areas with limited access such as this site Micropdes are mstalled using rotary or percussion dnllmg and
generate minimal disturbance or wbration to ad�acent structures

D Impact Justification and Mitigation
1 Avoidance and Mmimization
1a Specifically descnbe measures taken to avoid or minimize the proposed impacts m desigrnng pro�ect
Wall is laid out to follow the existing shape of the east bank between the intake and the bypass in order to mmimize impact to
the river bed Micropde foundation is proposed to reduce the potential footpnnt of more traditional foundation methods
1 b Specifically describe measures taken to avoid or mmimize the proposed impacts through construction techrnques
Micropde foundation is proposed since this foundation system is less impactFul in environmentally sensitive and hard to access
construction sites Construction of coffer dam at limits of construction shall limit the abdity of disturbed sediment to leave the
construction site Dewatering activities shall require water near the bottom of the work area to be pumped through sdt bags to
further limit chances of disturbed sediment from leaving the site It is proposed that the foundation and wall construction take
place from the east bank in order to further reduce impact to the nver

I IMPROVEMENTS TO 'THE
RAW WA'TER IIVTAKE STRUCTURE
� TOWN OF N�R'TH WILKES�ORO
i1 0 Executive Summary
The ob�ective of this preliminary engmeering report is to determine the feasibdity and
, costs associated with the improvements to the North Wdkesboro s existing raw water
intake structure
' The Town of North Wdkesboro utilizes the Reddies River as it raw water source The
Town s raw water intake is located on a smail impoundment approximately 1 400 feet
north of Business 421 Raw water is pumped to the�r 4 0 mgd water treatment plant and
' on to their distribution system after treatment Historically the Town discovered that the
raw water impoundment at the Town s mtake structure had silted up to the extent that it
was no longer possible to get any water into the intake structure The Town has
' completed the dredging of the impoundment area at a cost of more than $350 000 m
April 2009
' In order to increase the reliabiiity of dependable water supply to the Town of North
Wilkesboro the Town either contmues to dredge the impoundment periodicaliy at cost of
$350 004 or get water from Kerr Scott Reservoir
' Wdkes County commissioned Earth Tech of North Carolma to prepare a preliminary
engineering report with the ob�ective to determine the feasibility and costs associated
with the withdrawal of up to 24 mgd from the Kerr Scott Reservoir above the dam and
' conveyance of that water to the Towns of Wdkesboro s and North Wdkesboro s existing
water treatment facdities
1 While the Town of North Wdkesboro defirntely wants to pursue the option of gett�ng
water Kerr Scott reservoir they would like to keep the ex�st�ng intake structure on the
Reddies River With this background this PER focuses on alternatives for improvement
' of the intake structure only getting water from Kerr Scott will not be considered as
alternative
� This Preliminary Engineermg Report (PER) explored options to alleviate the sdting
problems and concluded that if a port�on of flow that goes over the dam is be diverted
through the sluice gate through a concrete channel in front of the �ntake screen a
' constant flow would be mamtained w�thm the channel to avoid any siltation The flow
splitting arrangement is sim�lar in concept to that of Wmston Salem intake structure
The overall pro�ect cost for the improvements to the mtake structure is estimated to be
' $472 400 and this PER can be used as a vehicle to obtam a grant from NC Rural Center
and the Town is prepared to meet the matching fund requirements (using Towns
General Funds)

2 0 Introduction ,
The Town of North Wdkesboro (Town) owns and operates a water supply facdity that
consists of an mtake on the Reddies River and a 4 0 MGD conventional water treatment �
plant The Reddies River empt�es into the Yadk�n River within a m�le downstream of the
Town s intake
Historically the Town discovered that the raw water impoundment at the Town s intake '
structure had sdted up to the extent that it was no ionger possible to get any water into
the intake structure The Town drained (using 6 wide 8 tall sluice gate) the
impoundment behmd the dam in order to force the river water to move forcefully beside '
and through the mtake structure The scouring velocity that ensued was sufficient to
clear a ditch from the mam flow of the river to the intake structure and allow water to
enter the structure When the impoundment had been drained it was discovered that '
the area behind the dam had become almost completely fdled in with sediment and sdt
There remained only approximately 2 5 feet to 3 0 feet of water above the sdt and beh�nd
the dam Fult water depth behind the dam should be 14 feet Therefore actual raw '
water storage volume behind the dam had been seriously depleted
Given the extent of the sdtation and sediment budd up behmd the North Wtlkesboro dam '
the NC Division of Water Quality, the NC Division of Water Resources and the NC
Public Water Supply Section have all strongly encouraged the Town of North Wdkesboro
to dredge the impoundment area and to actively pursue modifications to the intake
facility to try to keep the problem from reoccurrmg The Town has completed the 1
dredging of the impoundment area at a cost of more than $350 000 m April 2009 This
Preliminary Engineermg Report (PEFt) focuses on the modifications to the intake
structure to avo�d the sdtmg problems at the mtake '
3 0 Pro�ect Location
N rth Wdkesboro has its raw water intake situated on the Reddies River within a mile '
0
from the confluence of the Reddies River with the Yadkin River The intake sits behind a
dam on the river and the mtake is close to the north east bank of the river The dam was '
budt in 1934 and was originally used to furrnsh hydro electr�c power to the Town as well
as raw water for the water plant The old hydro electric plant and water plant were
housed in the same facdity which stdl stands on the south west bank of the river directly �
across from the intake structure These older bwldings are now used by the Town as
their mamtenance yard and fac�lities Water still flows from the r�ver through p�pes that
take it mto under the old hydro electric plant and back into the river below the dam '

51 Background Information
' The Town of North Wdkesboro utdizes the Reddies River as it raw water source The
Town s raw water intake is located on a small impoundment approximately 1,400 feet
' north of Busmess 421 Raw water is pumped to their 4 0 mgd water treatment plant and
on to their distribution system after treatment Historically the Town discovered that the
raw water impoundment at the Town s mtake structure had sdted up to the extent that it
was no longer poss�ble to get any water into the intake structure The Town has
' completed the dredgmg of the impoundment area at a cost of more than $350 000 m
Aprd 2009
' 5 2 Water Us�ges
The Town of North Wdkesboro provides water to its citizens and to several bulk users
' Approximately 1 040 mdlion gallons of raw water were treated by the Town s Water
Treatment Plant durmg a 12 month period from July 2006 to June 2007 This equates to
a dady withdrawal of approximately 2 85 mgd from the Reddies River A summary of the
' water usage for the twelve month period is presented in Table No 3
The Town typically provides water services to an average of 1 260 inside and 16 outside
' residential customers 541 commercial customers and 2 bulk customers Approximately
253 mdlion gallons of water were lost in the distribution systems and used in the
production of water at the water treatment plant The bulk users include Mulberry
' Fairplains Water Corporation and West Wilkes Water Corporation (formerly Cricket
Mdlers Creek Water Association) The Broadway Water Corporation purchased water
from North Wdkesboro in the past but now purchases all of their water from the Town of

5 3 Raw Water Supplies
The Town of North Wilkesboro ut�lizes the Reddies River as it raw water source The '
Town s raw water intake is located on a small impoundment approximately 1 400 feet
north of Business 421 The Reddies River is classified as WS II HQW CA from the ,
North Wdkesboro Water Supply Dam upstream to a point 0 4 miles south of Hoopers
Branch From that point upstream to the source the river is classified as WS II HQW 2
The Division of Water Qualrty defines WS II as waters protected as water supplies which ,
are generally m predominantly undeveloped watersheds 3 HQW is defined as high
quality waters which are rated as excellent based on biological and physical /chemical
characteristics CA refers to a critical area, which is defined as the area ad�acent to a '
water supply intake
The WS II classification limits development to 30 percent of budt upon area The
classification also requires local governments to control nonpoint sources and '
stormwater discharges in the watershed The critical area extends either '/� mile from
the normal pool elevation of the reserooi� or �/z mile upstream from and draining to the
intake or to the ridge line of the watershed (which ever comes first) Development ,
within the critical area is limited to no more than one dwellmg per two acres or 6 percent
budt upon area
A USGS surface water station No 0211500 is located 1 4 mdes upstream from the '
North Wilkesboro murncipal dam and has been collecting data since October 1939 The
dramage area of the water shed is reported to be 8 9 square mdes and produces an ,
average annual mean fiow of 33 262 million gallons (141 cfs or 91 mgd)
The maximum withdrawal rate that is typically allowed by the N C Division of Water ,
Resources for streams is 20% of the 7Q10 flow rate The remaining flow is allowed to
remain in the river for environmental uses The 7Q10 flow rate is defined as the
P e 6 ,

�
, minimum average flow for a period of seven consecutive days that has an average
recurrence of once in ten years "
� The lowest annual seven day low flow since water year 1940 is 14 cfs (9 0 mgd) and
was measured on August 8 2002 5 A summary of the seven day low flows is presented
in Table No 4 since 1999 Based on this North Wdkesboro would have been limited to
� withdrawal 1 8 mgd on August 8 2002 It could also limit the overali approved maximum
w�thdraw rate to 1 8 mgd However a greater withdrawal rate on a da�ly basis woufd
typically be allowed as long as 80%of the 7Q10 flow was allowed to flow downstream of
' the mtake

5 4 Water Treatment Facilities
5 41 Town of North Wilkesboro's Water Facilities '
The Town of North Wilkesboro owns and operates a 4 0 mgd conventional water i
treatment plant under NC Public Water Supply Number 01 97 010 The plant
ut�l�zes raw water from the Reddies River The raw water mtake is located on a
small impoundment approximately 1 400 feet north of Busmess 421 The �
impoundment is reported to have a storage volume of 52 miliion gallons but the
actual volume may be less due to the accumulation of mud and sediment The
locations of the raw water pump station and water treatment plant are shown in '
Figure No 3
The raw water intake and pump station is located on a small impoundment '
located approximately 1 mile upstream of the confluence of the Reddies River
and the Yadkin River The raw water supply facdities consist of a shore line
intake, two raw water pumps and a 16 inch raw water transmission main ,
The shore Ime mtake consists of a smali concrete structure located on the
water s edge that supports a 30 inch circular T shaped wire wound passive '
intake screen and a 30 inch by 24 mch emergency slide gate A 30 inch gravity
pipe connects the intake to the wet well located approximately 50 feet away The
screen is backwashed with air from an air compressor located in the ad�acent
pump budding '
The wet well is rectangular in shape houses two vertical turbine pumps on top
and sits ad�acent to a concrete budding The pump buddmg houses the valves �
and controls for the pumps the air compressor for the screen bac4cwash a
potassium permanganate feed system and an moperable stand by pump The
two vertical turbme pumps have a capacity of 3 200 gpm and are powered by ,
200 Hp motors The back up pump is an engine dr�ven hor�zontal split case that
is not operable The raw water pumps are not controlled by variable frequency
drives and the flow must be controlled by partially closing discharge valves ,
A 16 inch raw water mam leaves the pump station and discharges to the water
treatment plant approximately 950 feet away At the plant the raw water main �
mcreases in size to a 20 inch main and passes through a meter vault where a
venturi tube meters the flow The raw water main then discharges into a flash
mixer where chemicals are added and mixed ,
The treatment process consists of a flash mix basin two flocculation basins two
sedimentation basins and two fdters

5 5 Improvements to Intake Structure
,
In order to increase the reliabdity of dependable water supply to the Town of North
Wdkesboro the Town either contmues to dredge the impoundment periodically at cost of
� $350 000 or get water from Kerr Scott Reservoir
Wdkes County commissioned Earth Tech of North Carolina to prepare a preliminary
� engineering report with the ob�ective to determine the feasibility and costs associated
with the withdrawal of up to 24 mgd from the Kerr Scott Reservoir above the dam and
conveyance of that water to the Towns of Wdkesboro s and North Wilkesboro s existmg
� water treatment facdities
While the Town of North Wdkesboro definitely wants to pursue the opt�on of getting
, water from Kerr Scott reservoir they would like to keep the existing intake structure on
the Reddies River With this background this PER focuses on alternatives for
improvement of the intake structure oniy getting water from Kerr Scott will not be
� cons�dered as an alternat�ve
5 6 Future Water Needs
' The water usage rates have been pro�ected through the 20 year design per�od of 2030
and are summarized m Table No 6 The pro�ected water usage rates were estimated
, usmg the State Budget and Management Office s estimated growth rates for Wdkes
County Also the quantity of unaccounted for water was not increased This quantity
should remam the same or decrease as old water mains and meters are replaced

6 0 Alternatives for Raw Water Intake Structure Improvements '
61 Alternative No 1 — Do Nothing Alternative
With this alternative it would be necessary to dredge the impoundment periodically and i
incur expenses and the town residents could face interruption to their water supply In
addition this alternative will not fix the leaking sluice gate at the impoundment
in Alternative is not in the best interest of the Town of �
Implementation of the Do Noth g
North Wilkesboro and will not be considered further
�
6 2 Alternative No 2 — Relocate the Intake Structure
In order to a
void the sdt accumulation and clogging of the intake structure if the intake '
structure is relocated upstream of the impoundment however reviewmg the flow data
for the Reddies river upstream location wdl not take advantage of the impoundment ,
volume to contmue to withdraw raw water Relocating the intake structure upstream of
the impoundment could face the possibdity of runrnng dry due to shailow depth of the
Reddies River '
�
Impiementat�on of the Do Nothmg Alternative �s not in the best �nterest of the Town of
North Wdkesboro and vfnll not be considered further ,
6 3 Alternative No 3� Improvement to the Intake Structure
With this alternative a portion of flow that goes over the dam w�ll be diverted through the �
sluice gate and a concrete channel would be constructed in front of the intake screen
The flow splitting arrangement is simdar in concept to that of Winston Salem mtake �
structure
By opernng the sluice gate slightly a constant flow would be maintained within the
channel to avoid any sdtation at the intake By measurmg the water level of the '
impoundment and ad�usting the opernng of the sluice gate the flow over the dam and
through the sluice gate wdl be balanced Without the level measurement and automatic
gate openmg ad�ustment there is a potential that the impoundment could be emptied ,
The width of the channel near the sluice gate wdl be 6 to match the sluice gate openmg
The flow through the sluice gate for various open�ng can be calculated as follows

Based on the caiculation above the openmg of the sluice gate should be 0 5 with 14 of

channel At this opening if the total flow of the Reddies River is less than 88 47 cfs
than the level controller would ciose the gate A Computation Fluid Dynamic modeling of

'
the impoundment dam weir channel and sluice gate can be used to optimize the �
channel and also the width and opernng (width of the sluice gate) This modeling will be
performed dur�ng the sluice gate and channel design It may be necessary to reduce the
width of the sluice gate In other words a 3 wide x 8' deep sluice gate may be a better �
f�t for this situation
Additionally the riverbank near the �ntake structure and the sluice gate is eroding and '
wdl get worse when the flow is permanently directed towards the sluice gate To
stabilize the river bank slope the outer wall of the channel and river bank wouid be filled
with rip rap or a concrete retaining wall will be budt to protect the slope At the mouth of ,
the channel the mstallation of stop logs to an elevation of 972 would act as a
submerged weir' thereby holding sdt within the impoundment while protecting the
intake screen The height of stop logs can be lowered all the way to the bottom of the �
channel if necessary Figure No 5 illustrates the arrangements of this option
6 31 Environmental Impacts ,
There would be some impacts to the environment especially land disturbance to
construct the coffer dam and channei Any silt accumulated m the impoundment �
could be transported downstream however since the impoundment and the river
is recently dredged this impact would be mirnmal Other impacts mclude noise
and traffic durmg construction of this alternative Soi1 and erosion impact would �
be managed by way of an approved sod and erosion control permit from the NC
Division of Land Quality
There could be potent�al secondary impacts due to the proJect for example �
improved wastewater treatment could facilitate growth (encroachmg urban�zation)
w�thin the service area These impacts would be managed by implementing
floodplain and open space protection imposing limits on impervious surface �
managing stormwater and controlling sediment and erosion

No additional land would be required for this alternative
6 3 3 Construction Problems '
Although no construction problems are anticipated w►th this aiternative '
temporary pumping mto the intake structure would be necessary since the intake
structure would be isolated by coffer dam Installation of coffer dam would
require a barge within the impoundment ,
6 3 4 Operation Cost Estimates
There wili not be any addition annual operation and maintenance cost for this �
alternat�ve s�nce only the addit�onal power required operating the slwce gate is
negligent when compared to the overall operat�onal cost �

7 0 Present Worth Analysis
� Since only one viable alternative was identified a present worth analysis to compare
alternatives was not conducted Town of North Wilkesboro would like to continue to
proceed with the option of withdrawing water from Kerr Scott reservoir and when that
� happens w�thdrawing water from Reddies River would become a backup source of
water
� 8 0 Conclusions and Recommendations
� The conclusEOn of th�s preliminary engineering report is that it �s phys�cally and
economically feas�ble for the Town of North Wilkesboro to proceed wnth the viable
alternative identified m this report provided the Town is successful in getting a North
� Carolina Rural Center grant The Town will pay its share towards the grant using Town
funds and therefore there wdl not be any debt payment associated with the
impiementation of this alternat�ve Since this alternative does not increase any
' operational cost there wdl not be any mcrease to the water rates to its residents by
implement�ng this alternative
