Enclosed is a Modified PCN for NWP 12 and WQC #3884 for the referenced project. The property
owner is CCC- Boone, LLC represented by Amanda Wallis and the Applicant is Capstone Collegiate
Communities, Amanda Wallis is the contact. John Was with ENV Inc. is the agent (authorization letter
included with PCN) and has prepared this application. Copies of this PCN have been mailed to both
DWQ (5 with a check for $240 to cover 401 fee) and NCWRC.
This modification addresses a change to Impact Site #1 (S1). Specifically, the Applicant requests to
shift the crossing location downstream approximately 75 linear feet to address adjacent property owner
concerns and to utilize an existing gravel driveway for a portion of the proposed road. This modification
increases impacts at this location by approAmately 15 linear feet but will substantially reduce the
amount of proposed new road length and disturbed area near a small stream.
If you need to schedule a site visit please contact me. Please include ENV Inc. on the copy list of all
correspondence for this project. If you have any questions regarding this information please call me at

3. Project Description
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:
_Modification Text: The proposed modification to Impact Site #1 involves shifting the proposed
crossing location downstream approximately 75 feet. This location is essentially the same as the
previous crossing #1 location in all other respects.
Original PCN Text:
The project site consists of old pasture land and adjacent wooded land The old pasture area is close to
an existing farm house with out buildings and landscaped areas The proposed utility lines and access
road will pass just to the west of the farm house through an easement area cross a driveway and a
small perennial stream (UT- Laurel Fork -P) within the acquired easement (Impact Site 1) After the
first stream crossing the project passes out of the easement and onto Tract 2 of the Cottages of Boone
project site. The utility line and access road extends into a wooded area following an existing woods
road; a second crossing of an intermittent stream (UT- Laurel Fork -Int) will occur along this woods
road (Impact Site 2).
The site is accessed from Poplar Grove Road near NC Hwy. 105 a major transportation and
commercial corridor. Poplar Grove Road leading away (south) from Hwy 105 winds through mostly
rural agricultural, open, or low- density single family residential land use
Impact Site 1: This site involves a small first order perennial stream (UT- Laurel Fork -P) flowing
adjacent to an existing gravel driveway. The banks and riparian zone of this stream have been
consistently maintained by the property owners by mowing and weed - eating For several hundred feet
above Impact Site 1 the quality and character of the small stream has been influenced by landscaping
and other similar activities. The quality of this stream is good despite a history of minor impacts
Approximately 200 -feet below Impact Site 1 UT- Laurel Fork -P flows into the main stem of Laurel
Fork.
Impact Site 2: This site involves a small intermittent stream flowing through a wooded area The site
consists of an existing woods road that was constructed at least 25 years ago The graded width of the
existing road varies from 10 -feet wide to 25 -feet wide The woods road crosses UT- Laurel Fork -Int at
Impact Site 2. An 8 -inch clay pipe, approximately 24 -feet long was installed years ago but has become
domed at times and a gully has formed across the woods road from periodic high flow events The
clay pipe currently conveys base flow. Immediately below the woods road there is an eroded area
approximately 6 -feet deep with unstable vertical banks Two sections of the 8 -inch clay_ pine were
undermined and lay in the bottom of the gully; only 16 -feet of clay pipe is currently functioning_
Approximately 80 -feet below the woods road UT- Laurel Fork -Int flows into a wetland and into Laurel
Fork.
3b. List the total estimated acreage of all existing wetlands on the property: 0.012 acres
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
The project site contains approximately 200 linear feet of perennial stream and 40 linear feet of intermittent stream
Page 4 of 14
PCN Form — Version 1.3 December 10, 2008 Version
3d. Explain the purpose of the proposed project:
Modification Text: The purpose of the proposed modification to the location of crossing #1 is to
eliminate the need to construct a new road bed just above and to the west of the existing gravel driveway.
This modification will eliminate an area of rg ading approximately 200 feet long with 10 to 20 foot -tall
cut slopes. In place of the new road the existing gravel driveway is proposed to be used The alternative
alignment will involve minimal rg ading but much of it will occur within the trout buffer. A second
purpose for this modification is the adjacent landowners (the Vannoys - house shown on Site Plan) not
want a second road built adjacent to their driveway, they feel it would be an unnecessary disturbance and
would negatively impact their view from their front porch.
Original PCN Text:
The project purpose is to install utility lines from proposed student housing units to the proposed waste
water treatment plant (WWTP) and from the WWTP to various drip irrigation fields where the treated
effluent will be discharged. The project also involves construction of an access road necessary for the
installation and maintenance of the utility, lines.
3e. Describe the overall project in detail, including the type of equipment to be used:
Modification Text: The proposed modification will shift crossing #1 downstream by approximate
75 feet. Approximately 200 feet of proposed new road will be eliminated Necessary improvements
along the existing driveway will include widening by 2 or 3 feet in places installation of extra stone
and erosion control measures. There will be a brief period of intense use of this road lasting perhaps 6-
weeks. After this period usage will drop back to moderate levels for another 2 to 3 months After this
time usage will be minimal. The second crossing (previously permitted) remains the same
Original PCN Text:
The overall project is to develop a multi - family residential facility designated for student housing The
project will occur on two tracts of land purchased b the he Applicant and easements obtained by the
Applicant from adjacent land owners to allow for access between the two tracts The project site is not
served by municipal water or sewer; the Applicant has planned and received most of the approvals for
an on -site water and sewer system. This application is for a NWP -12 and WQC -3884 to authorize
impacts to jurisdictional waters at two locations associated with the installation of utility lines and the
construction of an access road. (See Avoidance and Minimization Section for extensive description of
the project)
Typical equipment will be used as part of site development: trackhoe backhoe bulldozer, and
dum truck.

Modification Text: This application is to modify permits NWP - #3 and #12 issued 7 -2 -2012 under Action ID 2012 -00428
and WQC 3890 issued 7 -20 -2012 under DWQ# 12 -0561
A PCN for a NWP -3 (WQC 3883) was submitted to USACE on May 14, 2012. Written authorization from NCDWQ was
not required for proposed activity but a courtesy copy of PCN was sent to DWQ. The proposed work involved
maintenance upgrade of two existing pipes within DOT jurisdiction. Both pipes were outside of the Cottages of Boone
project boundary but stormwater runoff was anticipated to impact both pipes and DOT made the pipe upgrades a
condition of the driveway permit. No permanent impacts were proposed, temporary impacts were 0.0023 acres of
wetlands and 20 linear feet of streams. Total impacts to streams and wet;ands associated with both PCN's will be 39
linear feet of permanent stream impact, 45 linear feet of temporary stream impact, and 0.0023 acres of wetland impact.

tight radius and an expanded headwall /retaining wall there will be additional encroachment into the upper banks of the
channel mostly on the upstream side of the crossing. In addition, a waiver to Condition #16 of WQC 3884 to allow greater than
40 feet of impact at the stream crossing location is requested.
Original PCN Text:
UT- Laurel Fork -P (S -1) will be permanently impacted by a 30 -foot long pipe for an access road and temporarily impacted by
installation of a grade control structure and construction activities. UT- Laurel Fork -Int (S -2) will be permanently impacted by
installation of a 25 -foot long pipe (replacing an existing 16 -foot long pipe) for an access road and temporarily impacted by
stabilization of an eroded bank at the pipe outlet and construction activities.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Modification Text: The proposed modification will result in 13 additional linear feet of permanent stream
impact and 2 additional linear feet of temporary impact However, the proposed pipe length is the same 30
linear feet, it is the proposed headwall /retaining wall that results in the additional impact but this wall still
allows for an open channel that will stabilize shortly after construction The intent of the modification will
reduce overall impacts for the project in two ways First by utilizing the existing driveway, which will require
only minor widening, a large area of new road construction will be eliminated Impacts avoided include
almost a half acre of land disturbance and a 10 to 20 foot -tall 2.1 cut slope Second Utilizing the existing
driveway addresses adjacent property owner concerns regarding aesthetics unrepaired impacts to their
driveway and extra runoff from a second road.
Original PCN Text:
The proposed project has been planned from the beginning to avoid and minimize impacts to jurisdictional
waters to the maximum extent practicable. The Applicant initiated an environmental consultant near the
beginning of the planning stage for the project to perform a wetland delineation and advise regarding potential
permit issues. Consequently, the project has been designed so that the vast majority of the land disturbing
activities will be located in upland areas well away from any streams or wetlands. The only impacts are
associated with utility line installation and maintenance access and two existing pipe upgrades required by
NCDOT as a condition of the driveway permit The DOT pipe replacement impacts have been addressed in a
separate application for a NWP -3 submitted to the USACE on May 14 2012
Utility Line Impacts: The Cottages of Boone project involves development activities on two tracts of land
separated by a narrow corridor, through which the Applicant has obtained an easement All of the roads and
buildings associated with proposed student housing are located on Tract 1 of the project Tract 2 was acquired
primarily as a location for on -site water and sewer systems required to serve the development The easement
will allow for access between the tracts for utility lines and associated maintenance access A small perennial
stream (UT- Laurel Fork -P) flows through the narrow corridor separating Tracts 1 and 2 There is an existing
driveway also located within this corridor and adjacent to UT- Laurel Fork-P. The easement connecting the
Page 9 of 14
PCN Form — Version 1.3 December 10, 2008 Version
two tracts, crosses both the driveway and the stream (Impact Site 1) and lines up with an existing woods road
on Tract 2 that leads to the proposed W WTP. The existing woods road crosses a small intermittent stream
(UT- Laurel Fork -Int) at Impact Site 2.
Utilizing the existing woods road minimizes impacts by eliminating the need to construct a new access road
across a sloping forested hillside. Constructing an access road around UT- Laurel Fork -Int would not be
practically feasible because the steepness of the road would make it extremely difficult if not impossible to
bring in the package W WTP and a pump station would be required for the sewer line. The location of the
easement and crossing of UT- Laurel Fork -P was selected to maximize distance between a house and the
easement while still allowing for usable access road to be constructed. No alternative locations are available
that would not also have to cross this stream and in some locations would have to cross it twice.
Impact Site 1: This crossing has been designed with dual 30" CMP's 30 -feet long with stacked boulder
headwalls. This design was selected as the least impacting practicable alternative. A bridge was contemplated
but construction of the abutments would have caused the driveway to be blocked for an extended period
(unacceptable to owners) the construction would likely have impacted the stream due to proximity, and the
cost was much greater. Temporary impacts to the stream channel will be necessary for construction a
temporary pump -a -round diversion, and to install a log grade control structure just upstream of the proposed
pipes.
Impact Site 2: The existing crossing consists of an 8" by 16' long clay pipe that was installed many years ago
This pipe has apparently become clogged or was overwhelmed at times and water flowed over the road
creating a small gully in the road and a large gully with steep eroding banks below the road The crossing was
in fact approximately 24 -feet long initially but two 4 -foot long sections of pipe broke off during the formation
of the gully. In order to repair this existing crossing dual 24" CMP's 25 -feet long are proposed The eroded
gully below the existing road will be stabilized with large boulders. Large boulders will also be keyed into the
streambed to prevent scour below the proposed pipes Temporary impacts to the stream channel will be
necessary for construction, a temporary pump -a -round diversion and to install keyed -in boulders below the
pipes.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Modification Text: Extra erosion control measures will be used along the existing driveway within the trout buffer to minimize
impacts to the maximum extent practicable throughout the construction phase At the completion of the period of intense use
the buffer area between the driveway and the stream will be planted with trees and shrubs to enhance the quality of the buffer
over what exists today. Currently the buffer consists of only mowed grass
Original PCN Text:
Permit conditions require that work be performed in the dry, therefore a pump -a -round system will be used at both impact
sites (see detail). Work will be coordinated so that each instream activity will be completed in one day

Photo 2: View looking northwest at both crossing
locations. The orange line is the currently permitted
alignment and the yellow line is the proposed
modified line. The yellow line on the far side of the
stream follows the existing driveway while the
orange line involves building a new road on the side
of the hill with a cut slope extending to the tree line.
Photo 3: View looking south at proposed modified
crossing location. The yellow lines show the
approximate road and the red rectangle is the
approximate impact area.
