Detailed Project Description
Including Equipment to be Used
Lake Evens Primary Spillway Maintenance
Buncombe County, North Carolina
The impoundment structure (Dam, Primary, and Emergency Spillways) for Lake Evens was designed by the
United States Department of Agriculture, Soil Conservation Service (SCS) in March 1962 and was
constructed later in the same year by the Presbytery of Western North Carolina (PWNC) SCS engineering
calculations and designs (Appendix A) for the Dam were found with the permission of PWNC, and assitance
from the Buncome County Soil & Water Conservation District / National Resource Conservation Service office
in Buncombe County, North Carolina A Site Location and Vacinity map has been included as Figure 1
This permitting package has been provided to the North Carolina Dam Saftey Program (DSP), North Carolina
Division of Water Resources (DWR) North Carolina Wildlife Resources Commision (WRC), and United States
Army Cops of Engineers (USACE) The purpose of this project is to repair the Primary Spillway Structure for
Lake Evens wick consists of Spillway Conduit, Bottom Drain Valve, and Spillway Riser A DSP figure "Parts
of an Earthen Dam" is included for reference as Figure 2 The construction of the Lake Evens impoundment
closely resembles this figure A Site Map is included as Figure 3 A Site Work Plan is included as Figure 4
and a Cross Section is included as Figure 5 Photographs with Captions of Lake Evens are provided as
Appendix B The earthen portion of the Lake Evens Dam structure appears completely intact to date and will
not be impacted or disturbed structurally as part of this maintenance
A DSP "Notice of Inspection with Maintenance" letter (Appendix C), dated March 24, 2008 and received by
PWNC, requested that woody vegetation be cleared from the downstream side of the Dam and that grassy
vegetation be re- established (completed in April, 2008 and maintained to date) The DSP letter also
requested that the Emergency Action Plan (EAP) for the Dam be updated An updated EAP for Lake Evens
has been provided to the DSP with this package The Lake Evens Dam is classified as a small, "B"
"Intermediate Hazzard" dam by the DSP
Mr Joel Lenk, PG and current caretaker of the -276 acre property, conducted a visual inspection of the Dam
and Primary Spillway infrastructure with the aid of a lighted, remote - controlled camera in May 2008 This
inspection revealed that the Bottom Drain Valve and Spillway Riser appeared to be in a deteriorating
condition and that the Spillway Conduit appeared to be in good condition The inspection also revealed that
relatively little sediment appears to have accumulated in the lake basin over its 50 year history Mr Lenk has
been caretaker of the referenced property (Youth Camp) since 2004, is familiar with and frequently inspects
the Lake and Dam structures Both the camera and frequent visual inspections by Mr Lenk suggest that the
earthen portion of the Dam and seal along the Spillway Conduit are intact and in good condition
It was known previous to the referenced 2008 camera inspection that the Spillway Riser was leaking and that
the Bottom Drain Valve was not functional These conditions limited control of the pond elevation in the Lake
The Dam was designed and constructed with an Emergency Spillway The Emergency Spillway has only
been observed by Mr Lenk during his eight year service as care taker, to have received flow during tropical
storms Francis and Ivan in late 2004 ( -100 -year storm) The Emergency Spillway is constructed at an
elevation one foot higher than the top of the Spillway Riser providing one foot of freeboard above the riser and
has dimensions of 35 feet bottom width with -3H 1V side slopes
In the winter of 2011, a precipitation event resulted in a high pond elevation in the Lake While the pond was
high, cold weather caused the formation of approximately eight inches of ice on the Lake surface During the
extended cold period, the water elevation beneath the ice fell as a result of the leaking Spillway Riser, frozen
surface water, and low precipitation The leaking riser caused the ice layer to become suspended above the
pond surface in the Lake When air temperatures rose above freezing the ice failed causing significant
damage to the deteriorated Spillway Riser The Lake slowly drained, through the damaged Spillway Riser
and intact Spillway Conduit to its current elevation (See photos Appendix B) approximately four feet above the
invert of the lake basin The earthen portion of the Dam, and infrastructure downstream of the Bottom Drain
Valve (Spillway Conduit Anchor, Anti- Seepage Collars, and Spillway Conduit) did not appear to be
compromised during this event It is observable that water does not appear to be bypassing the Primary
Spillway structure or Spillway Conduit to this day

Lake Evens, over its 50 year lifespan, has become an outstanding Bass and Sun Fish fishery The Lake also
supports approximately one acre of well - developed wetlands in three locations (where headwater tributaries
feed the Lake (see Appendix B) A variety of terrestrial, resident, and migratory wildlife depend on the Lake
and surrounding undeveloped land The Lake is also a key recreational and educational component of the
Camp property The subject property is located dust southeast of the Eastern Continental Divide between the
Broad and French Broad River Watersheds, and exists in its own micro- watershed at the top of the Broad
River Basin The property is almost entirely forested (approximately 98 %) and has been relatively
undisturbed by development for over 50 years These reasons help explain the small amount of sediment
that has accumulated in the Lake basin as evidenced by the aforementioned camera inspection The lake's
current pond elevation (approximately 14 feet below normal) sustains a reduced but intact population of
aquatic and terrestrial life that is expected to rebound quickly after maintenance of the Primary Spillway
system is complete and the pond elevation is returned to normal For these reasons the plan to conduct
maintenance of the Primary Spillway includes the creation of a "Sump" to allow for maintenance of the
Spillway structure "in the dry" and to sustain aquatic life during the work Maintenance of the Primary
Spillway system for Lake Evens is proposed to be conducted in the following way, using the equipment
described below, during a period of dry weather Maintenance is expected to take approximately 15 working
days Mr Lenk on behalf of TPWNC will be involved with and observe the project from the design and
permitting stage, to material selection and purchase, through contractor selection, and construction The
project is proposed to be completed in the following way
1 A Sump will be created upstream of the Dam, within southeast portion the Lake basin, which will allow for
maintenance of the Primary Spillway "in the dry" and will also hold a majority of the fish population during
maintenance Excavation of the Sump will not occur on or within the footprint of the Dam or its slopes
The Sump will be excavated using a track mounted excavator to a depth sufficient to hold a maximum
water depth of three feet with one foot of freeboard Dimensions of the Sump will be approximately 20
feet (width), 50 feet (length), and four feet (depth) with 2 1 internal side slopes Once the Sump is
created, a channel will be excavated, in the dry, from the Sump, upslope to near where the excavated
channel will intersect the existing channel that is flowing through the lake basin (Figures 2, 3, and 4)
Connecting the excavated channel and existing channel will not be completed until Step 3 of this plan and
the following items are completed first
Sandbags may be used on the lower (north) side of the excavated channel and Sump to help convey
water from the active channel and detain it in the Sump Sandbags will not be stacked more than two
bags high ( -16 inches) in any location and their placement will follow USACE methods for construction
(http / /www mvp usace army mil/ Portals /57 /docs /Operations %20Center /5Sandbag Construction 2009 J
RL pdf) The active channel (approximately one foot wide by eight inches deep), downstream of the
excavated channel / active channel intersection, will be temporarily blocked using sandbags and 10 and
plastic Sand bags will be filled with coarse grained material sourced from the excavation of the Sump
and excavated channel The Lake basin is currently stabilized with native grassy vegetation which will be
left intact to the extent possible to allow for maintenance This vegetation has and will continue to reduce
sediment impact to the tributary of Flat Creek throughout the project Additional sedimentation and
erosion control measures such as temporary seed, mulch, berms, and silt fence will be used as
appropriate to reduce the potential for sediment impacts during maintenance Excess soil produced from
the excavation of the Sump and channel will be spread in a flat, grassy, upland, athletic field located on
the property, blended into existing topography, and immediately stabilized with grassy vegetation by
installing seed mix and straw mulch (See Appendix B) Soil will be transported using a dump truck from
the lake basin to the athletic field along Woodson Road which is privately owned and maintained Grass
seed mixes used for sod stabilization will include annual grains and perennial turf vanetals appropriate for
the season, location, and quick germination Silt fence will be placed around downslope sides of the sod
disposal area, Sump and disturbed areas until all become stable Disturbance associated with the
maintenance will not exceed, or approach one acre in total
2 Two temporary spillways for the Sump have been designed to control water elevation in the Sump during
work These temporary spillways will be set up and be readied for operation prior to connecting the
excavated channel to the active channel, blocking the active channel, and filling the Sump as described
Page 2 of 5

above Both temporary spillway intakes for the Sump will be "floating" in order to limit sediment laden
water intake and outflow Turbidity levels in tributaries to Flat Creek will be held to less than 10
Nephelometric Turbidity Units (NTU) Temporary spillway one (TS -1), the primary temporary spillway for
the Sump, will be constructed of six -inch diameter schedule -40 PVC pipe that has been sized to
accommodate the base flow of water that enters the Sump from the tributaries that feed the Lake TS -1
will extend from dust below the water surface in the Sump, above ground, over the Lake Evens Dam to a
flat, grassy, discharge location at an elevation lower than the TS -1 intake downstream of the Dam Water
discharged from the temporary spillways will re -enter the tributary to Flat Creek as non - concentrated
sheet flow and groundwater that has run through and infiltrated the grassy discharge area The flow in
TS -1 will be initiated by siphon and controlled by a valve placed on the spillway's downstream end
Before the Sump is filled, the siphon for TS -1 will be primed by closing its valve, capping its upstream
end, and filling the pipe with water through a threaded "T" cap located at the highpomt in the TS -1 pipe
Temporary spillway two (TS -2) will consist of a three -inch trash pump, intake and discharge hose that will
extend from the Sump, over the Dam to a similar flat grassy location downstream of the Dam The
discharge location of both TS -1 and TS -2 will include splash mats to prevent erosion and disperse
concentrated flow TS -2 will only be used, if necessary, to maintain a constant pool elevation in the Sump
if there is a significant precipitation event during maintenance The discharge location, and area where
discharge water re- enters the tributary to Flat Creek, will be monitored and turbidity in the tributary
downstream of the discharge area will be kept below 10 NTU
3 Following the construction of the Sump and priming of its temporary spillways, water remaining around
the Primary Spillway for the Lake will be pumped into the Sump at the same time aquatic life is
transferred to the Sump At this point, the excavated channel will be connected to the active channel and
active channel will be blocked as described above in Step 1 Once the excavated channel is flowing to
the sump TS -1 for the sump will be activated The area around the Primary Spillway will then be allowed
to dry to the extent necessary to allow for maintenance of the Primary Spillway system Soil material
removed from the Lake Evens impoundment during maintenance will be spread in the athletic field as
described above The non - functioning Bottom Drain Valve and Spillway Riser will be cut from the
Spillway Conduit upstream of the Dam Anti- seepage collars, Spillway Conduit Anchors, or similar
structures near the upstream end of the Discharge Conduit will not be disturbed The Spillway Conduit
will be exposed using hand tools upstream of the Spillway Conduit Anchor (see Figures 2 and 4) The
Spillway Conduit will be cut at this location using a torch, cut -off wheel, or appropriate tool so that the
Damaged Bottom Drain Valve and Spillway Riser can be removed and disposed of properly
4 The existing 12 -inch inside diameter corrugated metal pipe (CMP) which makes up the Spillway Conduit
will be "slip - lined" with eight -inch inside diameter, thread pointed, smooth - walled, schedule 40 PVC pipe
Similarly, the existing Spillway Riser and Bottom Drain Valve will be replaced with a smooth walled riser
and plug valve of eight inches in diameter as described below The ability for the Lake Evens
impoundment structure to convey a storm event with a 100 year recurrence interval was modeled using
HydroCAD Additionally a Capacity Check for the structure to convey a 100 year storm at full capacity
was also performed The HydroCAD model and Capacity Check are included as Appendix D The Cover
Letter, the design, HydroCAD model, Capacity Check, and Figures 4 and 5 have been signed and sealed
by a North Carolina Licensed Professional Engineer In summary, base flow from the 67 acre drainage
area to Lake Evans was calculated to be 1 32 cubic feet per second (cfs) HydroCAD predicts that a
storm event with a 100 year recurrence interval (Type II 24 -hr Ashevdle100 Rainfall =7 69 ") plus base flow
will create a max inflow to the lake of 14149 cfs at 12 26 hours with a volume of 14 485 acre feet Max
outflow was predicted by the model to be 60 15 cfs at 12 67 hours as the available 5 5 acre feet of
storage is consumed and the max pool elevation of 1,940 72 (not relative to NAVD) is reached The
primary spillway was predicted to convey 2 14 cfs while the emergency spillway was predicted to
accommodate the remaining 58 01 cfs A Capacity Check was performed assuming that the Primary
Spillway is plugged, no storage is available, and that the entire outflow is routed over the Emergency
Spillway (Appendix D) Additionally, the SCS designs and calculations for Lake Evens appear to specify
the use of corrugated metal pipe of six - inches in diameter (Appendix A), however a 12 -inch CMP system
was installed Over his nine years as care taker, Mr Lenk has only witnessed the Emergency Spillway
functioning during the approximate 100 year storm event produced by tropical storms Francis and Ivan in
the fall of 2004 Damage to the Lake Evens was not observed as a result of these storms
Page 3 of 5

The eight -inch pipe will centralized using centralizers within existing 12 -inch CMP Spillway Conduit pipe
The eight -inch pipe will be pushed and joined from the upstream end until it protrudes from both the
upstream and downstream ends of the existing Spillway Conduit The annulus between the eight and 12-
inch pipes will be blocked at the downstream end with the exception of a one -inch vent pipe installed at
the top of the blockage The vent pipe will allow for air to escape from the annulus during grouting and
indicate when the annulus is full of grout at its downstream end When grout escapes from the vent pipe,
the vent will be permanently capped The annulus between the pipes will be pressure grouted along the
entire length using a grout pump, one -inch tremmie pipe with a length greater length than that of the
Spillway Conduit, and a Neat Cement grout made of Portland Cement and a minimum of five percent
Bentonite Clay The tremmie pipe will help insure a continuous grout seal between the new eight -inch
pipe and the existing 12 -inch Spillway Conduit
The existing CMP Spillway Conduit is oversized (based on the SCS design) and is 12- inches inside
diameter The Spillway Conduit is in good condition as indicated by the video of the inside of the pipe in
2008 The video confirmed the SCS specification that the conduit is spiral welded, asphalt coated, and
flange pointed Grout will be installed in lifts such that the heat of hydration is not great enough to impact
the new eight -inch PVC pipe Once grout has been installed within the entire annulus, grout within the
annulus of the new slip lined Spillway Conduit will be allowed to cure for no less than 24 hours before
maintenance resumes
5 Once the new conduit has been allowed to cure, an eight -inch, Schedule 40, PVC "T" will be installed on
the upstream end of the eight -inch PVC protruding from the slip lined conduit The "T" will be temporarily
supported and will exist near the old location of the Spillway Riser Eight -inch, thread pointed, schedule
40 PVC, which will make up the internal portion of the new Spillway Riser as well This section of eight -
inch pipe will be extended from the vertical orifice of the "T" to one foot below the elevation of the
Emergency Spillway (Figure 5 and Appendix A) and temporarily supported The new riser will provide
one foot of freeboard between the top of the Primary Spillway Riser and the Emergency Spillway invert
elevation as originally designed by the SCS
A new, steel reinforced, concrete filled, masonry Spillway Riser will be constructed around the eight -inch
PVC internal portion of the Spillway Riser and a trash rack will be installed on top of the riser at the "full
pond" elevation To accomplish construction of the masonry portion of the riser, deleterious material will
be removed from the area where a base for the new riser will be constructed The base of the new
Spillway Riser will be constructed by creating a square form, with a height of approximately one and one
half feet and a length and width of approximately six feet, beneath the eight -inch PVC "T" The form will
sit on in -situ soil in the approximate location of the old riser In situ soil within the form will be excavated
to a depth of approximately two feet below the bottom of the form A minimum of one foot of # 57 stone
will be placed in the form in six -inch lifts and compacted using a vibrating plate compactor One half inch,
steel reinforcing bar (rebar) will be tied and installed in the form A minimum of two feet of 5,000 pound
per square inch (psi), fiber reinforced, concrete will be installed in the form on top of the stone and around
the steel reinforcement The base of the new Spillway Riser will be allowed to cure for a minimum of 24
hours before maintenance continues
6 A -30 -inch wide masonry column will be constructed in the center of its new base, around the new eight -
inch PVC riser and "T ", upward, to an elevation of one foot below the Emergency Spillway invert
Elevations will be measured using a rotating laser accurate to one hundredth of a foot The masonry
column will form the outside of the new Spillway Riser and the eight -inch PVC riser will form the inside
The new masonry riser will be constructed to allow the pass- through of the eight -inch Spillway Conduit on
the downstream side of the "T" and a short section of eight -inch Schedule 40 PVC pipe extending from
the upstream end of the "T" to a new eight -inch, steel, Bottom Drain Valve (Plug Valve) that will be
located on the outside of the new masonry Spillway Riser The PVC portion of the riser will be centralized
within the masonry riser and one half inch rebar will be tied and installed in the annulus between the PVC
and the masonry parts of the riser The annulus, from the riser base, to the top of the Spillway Riser, will
be filled with 5,000 psi, fiber reinforced, concrete The new riser will be allowed to cure for a minimum of
24 hours before maintenance on the Spillway Riser resumes The new eight -inch plug valve will be
mechanically coupled to the PVC pipe upstream of the masonry riser and supported by a concrete
cradle(s) to allow for future maintenance of the valve A control shaft will be extended from the control
Page 4 of 6

point on the plug valve to an elevation approximately two feet above the top of the spillway riser The
control shaft will pass through several steel eyelets installed on the outside of the masonry riser for
support A removable control wheel will be fixed to the top of the control shaft so that the aperture of the
valve may be adjusted to control pond elevation from the surface of the Lake See Figures 4 and 5
7 A conical, inverted bucket style, or suitable trash rack will be installed on top of the new Spillway Riser
8 Before returning the pond in Lake Evens to normal elevation the control wheel and new Bottom Drain
Valve will be checked for proper function and adjustments will be made if necessary Temporary
spillways for the Sump will be disassembled once the new Primary Spillway is tested for correct
operation Sandbags, tools, equipment, and trash will be removed from the lake basin Vegetation
existing in the Lake Basin will be mowed Trash produced by the project will be disposed of property
After the repair of the Primary Spillway the pond elevation will be returned to normal elevation by partially
closing the new bottom drain (plug valve) The valve will not be closed completely until the pond
elevation reaches and spills into the top of the spillway riser in order to avoid starving the tributary of
water downstream of the dam Please note that several tributaries loin the stream immediately
downstream of the Lake Evens Dam and will contribute water to the stream throughout the project Water
in Lake Evens will not be allowed to rise more than one foot per day by adjustment of the bottom drain
valve It is anticipated that under normal climatic conditions the lake will take approximately 30 days to fill
to full pond elevation

SCS, Asheville, North Carolina
FROM T. J. Hossley, Civil Engineer
SCS, Newton, North Carolina
L SUBJECT ENGINEERING - Asheville Presbytery Pond, Buncombe County
Enclosed is design for the Asheville Presbytery Pond in
Buncombe County. It is lacking a tracing of drainage area,
Form NC -10, Soil Investigation, and tube location and
profile.
I have selected a tentative tube location, but I do not
know if the foundation is suitable. The NC -10 should show
if the entire length of the tube can be located on the
same type of material and there would be no unequal
foundation yielding. The pond size is lacking. I have
computed the yardage necessary to construct this dam.

Dear Madam
The "Dam Safety Law of 1967, as amended" provides forthe certification and inspection of dams
in the interest of public health, safety, and welfare, in order to reduce the risk of failure of such
dams, to prevent injuries to persons, damage to property, and to insure the maintenance of
stream flows.
Our records indicate you are the owner of the referenced dam that was inspected by personnel of
this office on March 12, 2008 The inspection revealed the following maintenance problems,
which must be addressed
• High bushes are growing on the dam again. Though you have cut this growth off the dam in
the past, you need to keep it off by re- cutting periodically. After cutting, a good grass cover
should be established and maintained.
During this inspection we also investigated the potential for property damage and loss of life in the
event your dam fails. This investigation determined that failure of your dam could result in
significant property damage Therefore, we are listing your dam in the "Intermediate Hazard"
category.
The Division of Land Resources must approve any excavation, modification, or major repair of the
dam. Draining the lake by cutting a notch In the dam, or otherwise breaching the dam, withbut
prior approval, Is a violation of State Law.

The "Dam Operation Maintenance and Inspection" manual published by this Department provides
inspection guidelines and recommended routine dam maintenance for the owner and emergency
procedures in the event of possible dam failure. A copy of this manual is available online at
http: /Ah%vw.dlr ennstate nc.us/ images /DamSafetyManual_rev_20061003 pdf or contact this office
Although we make every reasonable effort to determine the safety of your dam, our resources
limit us to a visual inspection. We hope that you will use the information provided in this letter as
you fulfill your obligation to safely maintain and operate your dam. Dams are constantly changing,
their spillways and conduits deteriorate and the dam itself is under constant pressure. Therefore,
you should keep a close watch on your dam and notify us if you detect any changes, especially
cracks, ground movements, or changes in seepage rate or color.
- �- In the event that a possible problem is found, you should contact a registered prdfessional
engineer and this office to inspect the dam In order to help us keep your records up to date and,
therefore, serve you better, please notify us concerning any changes in ownership. Your
cooperation in this effort is greatly appreciated
An updated Emergency Action Plan (EAP) will be required for this dam if one is not already on file.
If an existing EAP has not been updated in the past year, the downstream hazards shall be
checked and all contact information should be verified. Two copies of the EAP shall be submitted
to the Division of Land Resources, 1612 Mail Service Center, Raleigh, NC 27699 -1612, Attn:
State Dam Safety Engineer, and a copy shall be provided to the local emergency management
office
If you have an emergency situation during non -office hours, you should notify the Division of
Emergency Management's State Warning Point at 1-800- 662 -7956. They will notify the
appropriate personnel In this office of the situation. Should you have any questions concerning
this inspection, please contact Shawna Riddle or me at (828) 296 -4500 during normal office
hours.
Sincerely,

Mr. Lenk,
I have reviewed the project location that you requested. According to our records and a review of the
information provided, no listed species or their habitats occur on the site. Therefore, we believe the
requirements under section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must
be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed
species or critical habitat in a manner not previously considered, (2) this action is subsequently modified
in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is
determined.
You can check the box on the PCN, if you have not sent it in yet, that states you contacted our office and
we informed you that no federally listed species occurred in the project area. If you need additional
information or assistance please do not hesitate to give me a call.
Thanks

Dear Mr. Tomkins,
I appreciate your time. I am a NC licensed Geologist and am working on permitting the repair of a
primary spillway for a small privately owned lake, designed by the Soil Conservation Service, at a
wilderness camp Fairview, NC. Specifically, I am applying for a Nationwide Permit 3 for Maintenance
which requires submitting a Pre - Construction Notification (PCN) to NCDWQ and the USACE. The NC
Dam Safety Program will also be involved in the permitting. The PCN has not been submitted yet but I
am contacting you so that I may "check the box" in the PCN that I have contacted your office about the
project. My specialty as a Geologist is water resources and ecological restoration.
The coordinates for the site are 35.536596, - 82.330666. 1 have visited the USFWS and Asheville Ecological
Services Field Office web sites and have viewed and become familiar with the listed species for Buncombe
County. With exception of the potential for minor short term sediment impacts to small reach of an
unnamed tributary to Flat Creek, located in the Broad River Basin, the entire project will take place within
the lake basin and will not impact areas outside that basin other than the private gravel road accessing
the property, and approximately 1 /10th of an acre of upland athletic field located on the property where
excavated material from the lake bottom will be spread and stabilized with grassy vegetation. If you
would like to contact me about the project, please do so by replying to this email or giving me a call
at 828 - 280 -8375.
Thank you,
Joel Lenk, PG

Project Description
• Provide a detailed description of the proposed project, including the
acreage of the project area: Please see the attached "Description of the
Project in Detail ".
• List all licenses, permits, approvals, grants, or funding sought from federal
and /or state agencies: A Nationwide Permit 3 (Maintenance) is being
requested from the Army Corps of Engineers through submittal of a Pre -
Construction Notification (PCN). Concurrence and approval from the NC
Division of Water Resources and NC Dam Safety Program is being requested
through submittal of the same PCN package. The project is being paid for by
the PWNC and will not encumber state, federal, or grant funding.
• Describe all historic properties (buildings, structures, districts,
archaeological sites, or designed landscape features that are listed in, or
eligible for listing in, the National Register of Historic Places, or that are
50 or more years old) and located within or immediately adjacent to the
project area. Include photographs of all historic properties. For more
information on the location of historic properties, see the SHPO's new
online GIS Mapping Application at gis.ncdcr.gov /hpoweb /. Be sure to
check each of the HPOGIS Layers (National Register, Study List, etc.)
within your project area: SHPO's GIS website was referenced as described
above. No historic properties (buildings, structures, districts, archaeological
sites, or designed landscape features that are listed in, or eligible for listing in,
the National Register of Historic Places, or that are 50 or more years old) are
known to be located within or immediately adjacent to the project area other
than Lake Evens itself which is 51 years old and comprised of an earthen dam
and corrugated metal appurtenances.

• If the project proposes to rehabilitate, alter, remove, or demolish any
historic property within the project area, provide a description of the
historic property's current condition and the proposed
renovations: Proposed restoration of the lake's primary spillway system is
described in detail in the attached "Description of the Project in Detail ".
• Describe any proposed sale, transfer, or lease of historic properties within
the project area: Sale, transfer, or lease of historic properties within the
project area is not planned.
• If known, describe past usage of the project area, including any ground
disturbance that has taken place: Past usage of the project area prior to
PWNC ownership (circa 1960) is not known in detail, however evidence of
logging is apparent and agricultural use is assumed. The property is -98%
forested at present and has been used as a youth wilderness camp since
approximately 1964.
• Describe all proposed ground- disturbing activity within the project area,
including the nature, dimensions (length, width, and depth), and exact
location: Proposed ground- disturbing activities are described in detail in the
attached "Description of the Project in Detail" document, the Project Area Map,
and Photographs.
Project Area Map
• Submit a map showing the proposed project area. Road names must be
legible. Where available, provide state road numbers (SR 1234, NC 24,
etc.) All projects that propose ground- disturbing activity must also
include a U.S. Geological Survey (USGS) topographic map (or map
excerpt) showing the project area. The map should be sized to an 8 %" x
11" page and must identify the USGS quadrangle the project area is
located within. The USGS's National Map Viewer provides free online
access to and downloads of USGS 1:24K Index maps
at http: / /viewer.nationalmap.gov /viewer /: A Site Location and Vicinity Map is
attached. The site is located within the USGS Black Mountain Quadrangle
. The site is located at coordinates: DD: 35.536880 - 82.330060
DMS: 350 32' 12.763" N 820 19'48.210" W
USNG: 17S LV 79424 33397 (NAD 83)
MGRS: 17SLV7942433397
The quadrangle could not be attached because the files are too large for email
regardless of how they are
downloaded. The property on which the project is proposed is approximately 276
acres, is rural, and does
not include state maintained roads, and is private.
Site Photographs
• Photographs of the site are mandatory. Include photographs of all
structures within the project area that appear to be 50 or more years
old. All printed digital photographs should be a minimum size of 4" x 4"
(a maximum of 2 images per 8 %" x 11" page). For legibility purposes,
images taken from the internet (Google Street View, county tax appraiser
websites, etc.) cannot be substituted for digital photographs. If
submitting photographs of multiple structures clearly label the subject of

each photograph and ensure that the location of any detail photographs
or interior photographs can be identified: Project area photographs are
attached
Your assistance with this project is appreciated Please feel free to contact me with any
questions you may have
Sincerely,
Joel Lenk, PG
