PART 1. PROPERTY INFORMATION
1c. Property Size:
The overall property size is 20.24 acres. This is a combination of 9.41 acres for property PIN 0797948124 and 10.83 acres
for another property with PIN 0797933735.
PART 3. PROJECT DESCRIPTION
3a. Project Description:
The project is located on Mine Creek approximately 800 feet upstream of Lead Mine Road. The project involves analysis
and construction drawings to repair an eroded stream channel on Mine Creek adjacent to the North side of Valley Lake.
The project will include two properties the Montessori School of Raleigh at 7005 Lead Mine Road and HOA property for
Valley Lake.
The southern bank of Mine Creek within the repair area is experiencing extensive erosion on the southern bank. The
north bank of the stream within in the repair area has banks at bankfull elevations approximately 3 feet with good
access to the northern floodplain. The southern stream banks are on the outside of a meander bend and have vertical
banks that extend to heights 2 to 3 times bankfull. Extensive erosion has occurred in one location that has eroded the
bank approximately 25 feet laterally from its original location. The lateral migration south has paced the outside bend of
the stream within 30 feet of the top of Valley Lake's embankment. The erosional area is not currently within any fill
placed for the construction of the lake embankment.
The watershed contributing stormwater to the project site on Mine Creek has an area of approximately 0.65 square
miles and is not FEMA regulated in the repair area. The regional curve data for a watershed of this size is listed in Table
A.
Table A: Piedmont Regional Curve Data

The project reach classified as a C4 stream that is slightly entrenched. The northern bank is lower and has better
connection to the floodplain than the steep southern bank located on the outside of the meander bend. The following
morphological data included in Table B, was obtained from surveyed cross sections at riffle locations. Approximately 280

The site morphological data is within the data range for the urban curves
3d. Explain the Purpose of the Project:
The objective for the proposed design is to restore the bank stability and enhance the stream profile features. The
proposed design additionally provides for reestablishment of the channel to a typical riffle and pool cross section
through the project reach, based on the morphological data collected on the stable reference segment located directly
upstream of the repair area.
3e. Describe the Overall Project in Detail, Including the Type of Equipment to be Used:
Pool to pool spacing, riffle lengths, and riffle slope data collected in the upper reach was utilized to re-establish
appropriate riffle and pool locations through the repair area. The stream slope was established over a 450-foot stream
segment to get a comprehensive view of the repair area and beyond its extents. The bankfull and stream slopes along
this reach were used to set the proposed constructed riffle elevations.
The northern bank will be preserved in the design as much as possible as this bank is in good shape and is currently
stable. The southern bank will be modified to include slope improvements to 2H:1V or greater banks and
reestablishment of a stable cross section geometry. The provision of a wider floodplain bench was incorporated into the
areas of lateral migration where possible. The existing stream through the repair area had two submerged riffles. The
proposed design includes two constructed riffles and re-establishment of one pool in the reach. The riffles were located
to enhance the submerged features and were place with appropriate spacing obtained from the upstream reference
area. The severe bank migration areas will be filled. A rock toe is planned in fill areas to bankfull to prevent erosion while
the stream bank is revegetating. The lake overflow channel to the west and a drainage channel that enters from the
north will be transitioned and stabilized with rock to prevent future head cutting.
The proposed bankfull channel and benching is based on a bankfull slope of 0.005 ft/ft with bankfull elevations
determined in the morphological analysis. The channel design is based on a cross sectional area of approximately 39.7
square feet in the riffle sections with pool areas approximately 25% larger. The pool area is anticipated to adjust over
time with sediment deposition and point bar formation. The proposed channel will remain in the approximate location
of the current channel with toe adjustments at scoured locations reconstructed at approximated original toe locations.
The stream bank corridor within the repair area will be re -vegetated along both sides of the stream along with the
bankfull bench. The re -introduction of vegetation to the graded channel banks will aid in providing long term bank
stability. The vegetation will be a combination of native herbaceous and woody plant species. The stabilized banks and
re -vegetated corridor will additionally provide stormwater quality benefits.

Supplemental Information, PCN Applications

The equipment to be used in the project is earth moving equipment and various other support apparatuses. The stream
normal flow will be pumped around the project site. Stabilization will occur daily within the work area. Heavy equipment
may include hydraulic excavator, compactors, bulldozers, skidsteer loaders, and dump trucks to load and unload
materials. The construction equipment will enter the site from the existing gravel driveway. The construction equipment
will enter the lower reach site from existing gravel driveway. All construction will be performed within a defined limit of
disturbance.
SECTION C— PROPOSED IMPACTS INVENTORY
3i. Stream Impacts:
S1: Stream stabilization will be provided on the bank through reconstruction to a typical channel cross section, rock toe
reinforcement in reconstructed areas, and installation of erosion control matting and riffle construction. The profile will
be stabilized through the provision of constructed riffles. The over widened channel will be constructed to a typical
width and bankful benches constructed in scour areas. The benches will provide flow transition during high flow events
reducing stress in the channel
6i. Buffer Impacts:
The top of the stream bank will be relocated due to the bank stabilization work to be conducted on both sides of the
bank. The changes in the buffer involve a 356-sf area. That will be reestablished as buffer. This area will be covered with
C700 erosion control matting, seedling replanted with woody vegetation.
The top of the stream bank will be relocated in some areas due to the bank stabilization work to be conducted on the
bank and erosion control matting will be placed to bank full. The changes to the buffer involve a 51-sf area.
Areas will be impacted due to construction access and development of a bankfull bench on both side of the stream. The
buffers on the south side of the stream will be re-established with native grasses and woody vegetation as shown on the
stabilization plan
SECTION D — IMPACT JUSTIFICATION AND MITIGATION
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
This project is necessary due to the active bank erosion that is encroaching an existing pond dam in the Hidden Valley
Subdivision. The project will stabilize the stream channel and eliminate active erosion of the stream channel bank and
bed. The repaired channel will enhance aquatic habitat with reconstruction of typical riffle pool segment. The
minimization of the project includes working with the existing stream pattern with limited pattern changes and
enhancement of a floodplain bench to lessen the stress on the stream banks at the outer bend during large storm
events. The limit of disturbance has been minimized to only the area needed to construct the repairs. Impacts to the
stream buffer will be minimized by accessing the site through a narrow corridor and protection of as much existing
vegetation as possible.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Pumping of normal stream flow be maintained and pumped around the site during construction activities. Bank
stabilization, covering the slope with erosion control matting, will occur daily upon completion of bank grading.
Permanent erosion control matting will be installed on all stream banks above rock toes.

SECTION F — SUPPLEMENTARY INFORMATION
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated
Critical Habitat?
The site is an existing urban residential area that has been previously impacted by development. The existing sanitary
sewer easement is currently being mowed and maintained. Habitat is not present for Wake County listed vertebrate and
invertebrate endangered species with the exception of Northern Long Eared Bats. It is not anticipated that the limited
tree removal would be an impact to critical habitat for the Northern Long Eared Bat in Wake County. Therefore, it is not
anticipated that there will be any adverse impacts associated with T/E species.
