Re: Mount Airy Golf Course Stream Restoration Project
401/404 Pre-Construction Notification Application
Dear Mr. Matthews and Ms. Dennison:
Enclosed for your consideration and approval is the Pre-Construction Notification for the US Army Corps
nationwide permit 27 and the Division of Water Quality's general certification 3495 for stream restoration,
enhancement, and stabilization for the Mount Airy Golf Course Stream Restoration Project. This project is
located in Surry County. Also enclosed are copies of the Mount Airy Golf Course Stream Restoration Plan for
your reference in reviewing the PCN application. Please note that we have requested the application be
reviewed before September 2009 to enable site preparation to take place so that the wetland plant species may
be planted during the appropriate dormant season at the end of this year. Thank you in advance for your
assistance.
The project meets the DWQ definition of stream restoration activities greater than 150 feet and
funding was provided by Clean Water Management Trust Fund. Therefore a permitting fee has
been included with this package. This is not for a stream mitigation project.
If I can be of any further assistance, please contact me at [phone].

INTRODUCTION
This narrative is submitted as part of the proposed Stream Restoration and Enhancement
Project Plan for the Mount Airy Country Club Stream Restoration Project. Construction
of the project will involve the restoration or enhancement of approximately 2,100 linear
feet (LF) of tributaries to Lovills Creek.

PROJECT DESCRIPTION
Baker Engineering proposes to restore or enhance approximately 2, 100 linear feet along
two unnamed tributaries to Lovills Creek. The two tributaries flow through Mount Airy
Golf Course in Surry County North Carolina, near the Town of Mount Airy (Figure 1).
The site lies in the Yadkin Pee-Dee River Basin within North Carolina Division of Water
Quality sub-basin 03-07-03. The center point of the site is located at 36.5215° N latitude
and 80.6142 ° W Longitude. The project drains 0.23 square mile and 0.18 square miles
through two unnamed tributaries labeled UT 1 and UT 2, respectively (Figure 2).
The project is located on Mount Airy Country Club property. Most of project is open and
mowed up to the stream bank except for wooded sections along the upper left side of UT
2. The two tributaries (UT 1 and UT 2) provide little habitat and have little riparian
buffer. Total disturbed area for stream and buffer restoration is approximately 6.8 acres.
Riparian buffer will be established along UT 1, UT 2, and Lovills Creek.
SITE CONDITIONS
There are two unnamed tributaries (UT 1 and UT 2). UT 1 is overly wide and UT 2 is
incised throughout most of the reach. The lack of riparian buffer is facilitating the erosion
of the stream banks on both tributaries. Parts of UT 1 are clogged with live grasses
blocking the transport of sediment except at high flows. UT 1 and UT 2 offers little
bedform diversity throughout there current alignments. The lack of bedform diversity
provides little habitat for native wildlife species. The soils in the project area are
primarily Colvard and Suches soils with small areas of Rhodhiss-Bannertown (Figure 3).
Local relief within the project site is approximately 15 feet. Surrounding properties are
characterized primarily by wooded residential neighborhoods and agricultural cropland.
EROSION AND SEDIMENTATION CONTROL MEASURES
Erosion control methods to be used onsite include silt fences, temporary construction
entrances, rock dams, mulch, temporary seeding, permanent seeding, and erosion control
matting and a pump around operation. All sediment and erosion control measures are to
be built according to the plans and specifications.
Bench grading activities will be graded away from the flowing channel. Cut material will
be stockpiled as shown on the plans. Silt fences will be used to prevent erosion of the
stockpiles toward the open stream areas on site.
Temporary rock dams will be installed on the downstream end of haul road ditch
crossings. Silt fences will be used to prevent erosion of disturbed ground toward any
flowing streams on site.
Pump around operations will be utilized.
DESIGN STANDARDS
Standard erosion control practices, methods, and procedures described in these plans and
specifications are based on those presented in the North Carolina Erosion and Sediment
Control Planning and Design Manual (2006).
MAINTENANCE PLAN
Qualified personnel on a daily basis will evaluate all temporary erosion and sediment
control practices for stability and operation. Weekly inspections will be performed and
logs kept. A rain gage will also be kept on site and rainfall amounts recorded. Any
repairs needed, will be performed immediately to maintain all practices as designed. The
selected Contractor will be responsible for the maintenance of temporary on-site erosion
control measures. The Contractor will be responsible for implementing and following the
approved Sediment and Erosion Control Plan.

construction operations. Temporary seeding will be used on all areas susceptible to
erosion, including, but not limited to ditch banks, access areas, steeper slopes, and areas
where excess soil will be spread over upslope fields. Seeding will take place
immediately after construction activities are completed in the disturbed areas. The work
shall consist of preparing the area, furnishing and placing seed and mulch, and anchoring
mulch in the designated areas as specified.
EQUIPMENT AND MATERIALS
Temporary Seeding
For temporary seeding, apply the following vegetation at the listed rates and times. A
combination of the two seed types shall be used during the boundary months of March,
April, August and September to ensure survival.
Temporary Seeding (September to March):
Rye grain 130 lbs per acre
Temporary Seeding (April to August):

Mulching
Mulching shall be used to provide temporary protection of soil surfaces from erosion.
Mulching should be performed within 48 hours of seeding. Grain straw mulch should be
applied on seeded areas at a rate of 130 bales per acre. Apply mulch uniformly.
METHODS
On sites where equipment can be operated safely, the seedbed shall be adequately
loosened. Disking may be needed in areas where soil is compacted. Steep banks may
require roughening, either by hand scarifying or by equipment, depending on site
conditions. The Engineer will determine condition needs onsite. If seeding is done
immediately following construction, seedbed preparation may not be required except on
compacted, polished or freshly cut areas.
Mulching is used to provide temporary protection of soil surfaces from erosion. Mulching
should be performed within 48 hours of temporary seeding. Grain straw mulch should be
applied on temporary seeded areas at a rate of 3 bales per 1,000 ft (130 bales per acre).
Mulch shall NOT be applied on streambanks when coir fiber matting matching C7
specifications is used. Apply mulch uniformly.

I. PERMANENT SEED
SCOPE
The work shall consist of applying permanent seeding on the site for the purposes of
establishing stream buffer, wetland vegetation and controlling erosion. Permanent
seeding will be placed on all disturbed areas targeted for stream buffer, or where grading
and earthmoving activities have left exposed soil when construction in the area is
completed. Seeding will take place immediately after construction activities are
completed. The work shall consist of furnishing and placing seed in designated areas.
EQUIPMENT AND MATERIALS
Apply the following vegetation at the listed rates. Species may be substituted or removed
from the specified mixtures upon approval of the Project Manager.

Engineer/ Project Manager. Fold over and bury matting to the full depth of the trench,
close and tamp firmly. Overlap matting at least 6 in. (150 mm) where 2 or more widths
of matting are installed side by side.
Place stakes across the matting at ends, junctions, and check trenches approximately 1 ft.
(90.3 m) apart with notch facing upslope.
Place stakes along the outer edges and down the center of each strip of matting 3 feet (1
meter) apart. Place stakes along all lapped edges l ft. (0.3 m) apart. Refer to details in the
plan sheets.
The Engineer/ Project Manager may require adjustments in the trenching or staking
requirements to fit individual site conditions.
P. TRANSPLANTS
SCOPE
The work shall consist of the removal, transport, and placement of available on-site
vegetative material for the purpose of streambank stabilization and enhancement of
stream habitat.
16
EQUIPMENT AND MATERIALS
The Contractor shall provide a rubber tired or track loader for the excavation, transport
and installation of transplanted vegetation. The Contractor must have approval from the
Engineer before using any other type of equipment for installing transplants.
METHODS
Shrub and trees less than 3 inches in diameter shall be salvaged onsite in areas designated
for construction, access areas, and other sites that will necessarily be disturbed.
Vegetation to be transplanted will be identified by the Engineer personnel. Transplanted
vegetation shall carefully be excavated with rootballs and surrounding soil remaining
intact. Care shall be given not to rip limbs or bark from the shrub and tree transplants.
Vegetation should be transplanted immediately, if possible. Otherwise, transplanted
vegetation shall be carefully transported to designated stockpile areas and heeled-in in
constantly moist soil or sawdust in an acceptable manner appropriate to weather or
seasonal conditions. The solidity of the plants shall be carefully preserved. Individual
transplants shall range in size from 0.5 to 2 square yards in size.
Installation of shrub and tree transplants shall be located in designated areas along the top
of the stream bank or in floodplain restoration areas as directed by Engineer. Soil in the
area of vegetation transplants shall be loosened to a depth of at least 1 foot. This is only
necessary on compacted soil. Transplants shall be replanted to the same depth as they
were originally growing. The planting trench or hole shall be deep and wide enough to
permit the roots to spread out and down without J-rooting. The plant stem shall remain
upright. Soil shall be replaced around the transplanted vegetation and tamped around the
shrub or tree finely to eliminate air pockets.
Spacing and location of vegetation transplants will be determined onsite by the Engineer.
Q. LIVE STAKING
SCOPE
There will be limited live staking vegetation planted. Containerized or balled and burlap
vegetation will be used on the floodplain. The work shall consist of the planting of live
stakes on specified stream banks to be protected from erosion. The Contractor will be
responsible for identifying a source for live stakes near the project site, collecting and
delivering the live stakes to the project site, and installation of the live stakes. Staking
must take place during the dormant season (December - February).
17
EQUIPMENT AND MATERIALS
Live stakes may be of the following species:
Live staking will be applied to all restored streambanks, except within the area marked Golf course zone,
following the details in this plan set and according to the constructionspecifications.
Common Name Scientific Name Wetness Tolerance
Silk Willow Salix sericea OBL
Black Willow Salix ni a OBL
Silk Dogwood Cornus amomum OBL
Elderberry Sambucus canadensis OBL
METHODS
Live stake materials should be dormant and gathered locally or purchased from a
reputable commercial supplier. Stakes should be '/2 to 2 inches in diameter, 2 to 3 feet in
length, and living based on the presence of young buds and green bark. Stakes shall be
angled on the bottom and cut flush on the top with buds oriented upwards. All side
branches shall be cleanly trimmed so the cutting is one single stem. Stakes should be kept
cool and moist to improve survival and to maintain dormancy.
Planting shall take place during the months of December - February. Stakes should be
installed 2 to 3 feet apart along the stream banks on the outside of meander bends and 6
to 8 feet apart along the stream banks on the inside of meander bends and through tangent
sections. Live stakes shall be installed along streambanks above the base flow water
surface elevation. Site variations may require slightly different spacing. Stakes shall be
driven into the ground using a rubber hammer or by creating a hole and slipping the stake
into it. The stakes should be tamped in at a right angle to the slope with 4/5 of the stake
installed below the ground surface. At least two buds (lateral and/or terminal) shall
remain above the ground surface. The soils shall be firmly packed around the hole after
installations. Split stakes shall not be installed. Stakes that split during installations shall
be replaced.
R. CONTAINERIZED VEGETATION
SCOPE
There will be no bare-root vegetation planted. Containerized or balled and burlaped
vegetation will be used in the specified planting zones.

S. SAFTEY FENCE
SCOPE
The work of "Safety Fence" shall consist of furnishing, installing and maintaining
polyethylene or polypropylene fence at locations shown on the plans or as directed by the
Engineer/ Project Manager in accordance with special provisions included herein.
Sections of safety fence shall be installed within one working day following mobilization
operations. Unless prior approval is received from the Engineer/ Project Manager, failure
to install the fence as specified herein will result in stoppage of all operations until the
necessary safety fence is installed.
MATERIALS
Polyethylene or polypropylene fence shall be pre-constructed safety fence approved by
the Engineer/ Project Manager.
Steel posts are required and shall be a length of at least 5 feet; approximately 1 3/8" wide
measured parallel to the fence, and have a minimum weight of 1.25 lb/ft of length. The
steel post shall be equipped with an anchor plate having a minimum area of 14 square
inches.
CLEARING AND GRUBBING
No additional clearing and grubbing is anticipated for the installation of this fence;
however, if any clearing and grubbing is required, it will be the minimum required for
installation of the safety fence. Such clearing shall include satisfactory removal and
disposal of all trees, brush, stumps and other objectionable material.
The fence shall be installed to conform to the general contour of the ground. When
determined necessary by the Engineer/ Project Manager, minor grading along the fence
20
line shall be done to meet this requirement provided no obstructions to proper drainage
are created.
INSTALLATION
Posts shall be set and maintained in a vertical position and may be hand set or set with a
post driver. If hand set, all backfill material shall be thoroughly tamped.
The fence fabric shall be attached to the steel posts with wire or other acceptable means.
The Contractor shall be required to maintain the safety fence in a satisfactory condition
for the duration of the project as determined by the Engineer/ Project Manager.
T. CONSTRUCSTION SEQUENCE
A Baker Engineering Project Manager will provide construction observation during the
construction phase of this project. The following construction sequence shall be used
during implementation of the plan.
1. Prior to beginning any land disturbing activities, notification and approval must
be granted from NCDENR Division of Land Resources - Land Quality Section,
US Army Corp of Engineers, and NC Division of Water Quality.
2. The Contractor shall contact North Carolina "One Call" Center (1.800.632.4949)
and Land Quality (919.791.4200) before any excavation.
3. The Contractor will mobilize equipment and materials to the site by installing and
using the construction entrances (that are shown on the plans) along Country Club
Rd. The construction entrance will need to be upgraded.
4. The Contractor will utilize the haul roads and stream crossing as shown on the
plans. Construction traffic shall be restricted to the areas on the construction
plans.
5. The Contractor shall install temporary silt fence around the staging area(s).
6. The Contractor shall install all temporary stream crossings as shown on plans in
accordance with the NC Erosion and Sediment Control Planning and Design
Manual. Ditches and stream reaches on site will be left open during the initial
stages of construction to allow for drainage and to keep site accessible.
7. Contractor shall begin construction on each stream reach and complete that
stream reach before moving to the next reach. The new channel sections shall be
left open on the downstream end to allow for drainage during rain events. A
temporary rock dam shall be installed at the downstream end.
8. Perform all work in the dry along UT 2. At the upstream end of the new channel
(approximately Station (11+20) leave a 10 foot plug of earth at the existing stream
bank between the new and old channel.
9. Construction shall begin at the end of the UT 2 proceeding upstream with
excavation of the bench, followed by the stream alignment and structures. Once
UT 2 has been excavated to design grades, install in-stream structures, seed and
21
mat with erosion control fabric, and ready the channel to receive flow into the
new channel.
10. Turn water into the new channel by removing the earthen plug at the upstream
end of the new channel (approximately Station 11+20) and immediately begin
plugging, filling, and grading the abandoned channel, as indicated on plans,
moving in a downstream direction to allow for drainage. The water hazard may be
filled at anytime during construction to reduce fill.
11. Contractor shall only work in areas that can be seeded, mulched, and matted
within the same day.
12. To reduce disturbance, the haul road connecting UT 1 and UT 2 construction site
maybe utilized no more than once by heavy machinery. Construction of the new
cart path shall also be done before transition to the UT 1 construction area. Begin
construction sequence on UT 1 from Station 10+50 to Station 17+98 by installing
temporary silt fence around the staging area(s). Temporary silt fence will also be
placed around the temporary stockpile areas as material is stockpiled throughout
the construction period; as shown on the plans.
13. Perform all work in channel along UT 1. The section between Station 10+00 and
17+98 requires the use of a temporary pump-around operation as noted in the
Plans. The Contractor shall install a temporary rock dam and pump-around
operation for this section. The portion of channel isolated shall be dewatered and
the removed water shall flow through a special stilling basin according to project
special provisions.
14. Once construction in the pump-around area (10+00 to 17+98) has been excavated
to design grades, install in-stream structures, seed and mat with erosion control
fabric in disturbed areas and remove all pump-around materials. Contractor shall
only work in areas that can be seeded, mulched, and matted within the same day.
15. Upon completion of the re-centered channel and structure instillation on UT 1,
remove temporary stream crossings and any in-stream temporary rock dams. All
disturbed floodplain areas including staging areas haul roads, and filled pond,
shall be seeded and covered with mulch. Permanent seeding mixtures shall be
applied as shown on the vegetation plan. Temporary seeding shall be applied in
all areas susceptible to erosion (i.e. disturbed ditch banks, steep slopes, and spoil
areas) such that ground cover is established within 21 working days following
completion of any phase of grading. Permanent ground cover shall be established
for all disturbed areas within 15 working days or 90 calendar days (whichever is
shorter) following completion of construction. All areas should be seeded and
mulched before leaving the project reach. All waste material must be removed
from the project reach.
16. Prior to seeding and mulching the haul road, the new cart path shall be built as
shown on the plans and in the details.
17. The Contractor shall plant woody vegetation according to planting details and
specifications. They should complete the reforestation phase of the project and
apply permanent seeding at the appropriate time of the year.
18. The Contractor shall ensure that the reach is free of trash and leftover materials
prior to demobilization of equipment from the site.

GENERAL CONSTRUCTION SEQUENCE
The following construction sequence shall be followed by the Contractor.
1. Prior to beginning any land disturbing activities, notification and approval must be granted from NCDENR Division of Land Resources -
Land Quality Section, US Army Corp of Engineers, and NC Division of Water Quality.
2. The Contractor shall contact North Carolina "One Call" Center (1.800.632.4949) and Land Quality (919.791.4200) before any excavation.
3. The Contractor will mobilize equipment and materials to the site by installing and using the construction entrances (that are shown on the
plans) along Country Club Rd. The construction entrance will need to be upgraded.
4. The Contractor will utilize the haul roads and stream crossing as shown on the plans. Construction traffic shall be restricted to the areas on
the construction plans.
5. The Contractor shall install temporary silt fence around the staging area(s).
6. The Contractor shall install all temporary stream crossings as shown on plans in accordance with the NC Erosion and Sediment Control
Planning and Design Manual. Ditches and stream reaches on site will be left open during the initial stages of construction to allow for
drainage and to keep site accessible.
7. Contractor shall begin construction on each stream reach and complete that stream reach before moving to the next reach. The new channel
sections shall be left open on the downstream end to allow for drainage during rain events. A temporary rock dam shall be installed at the
downstream end.
8. Perform all work in the dry along UT 2. At the upstream end of the new channel (approximately Station 11+20) leave a 10 foot plug of
earth at the existing stream bank between the new and old channel.
9. Construction shall begin at the end of the UT 2 proceeding upstream with excavation of the bench, followed by the stream alignment and
structures. Once UT 2 has been excavated to design grades, install in -stream structures, seed and mat with erosion control fabric, and ready
the channel to receive flow into the new channel.
10. Turn water into the new channel by removing the earthen plug at the upstream end of the new channel (approximately Station 11+20) and
immediately begin plugging, filling, and grading the abandoned channel, as indicated on plans, moving in a downstream direction to allow
for drainage. The water hazard may be filled at anytime during construction, see plans sheets for location.
11. Contractor shall only work in areas that can be seeded, mulched, and matted within the same day.
12. To reduce disturbance, the haul road connecting UT 1 and UT 2 construction site maybe utilized no more than once by heavy machinery.
Construction of the new cart path shall also be done before transition to the UT 1 construction area. Begin construction sequence on UT 1
from Station 10+50 to Station 17+98 by installing temporary silt fence around the staging area(s). Temporary silt fence will also be placed
around the temporary stockpile areas as material is stockpiled throughout the construction period; as shown on the plans.
13. Perform all work in channel along UT 1. The section between Station 10+00 and 17+98 requires the use of a temporary pump -around
operation as noted in the Erosion Control Plans. The Contractor shall install a temporary rock dam and pump -around operation for this
section. The portion of channel isolated shall be dewatered and the removed water shall flow through a special stilling basin according to
project special provisions.
14. Once construction in the pump -around area (10+00 to 17+98) has been excavated to design grades, install in -stream structures, seed and mat
with erosion control fabric in disturbed areas and remove all pump -around materials. Contractor shall only work in areas that can be seeded,
mulched, and matted within the same day.
15. Upon completion of the re -centered channel and structure instillation on UT 1, remove temporary stream crossings and any in -stream
temporary rock dams. All disturbed floodplain areas including staging areas haul roads, and filled pond, shall be seeded and covered with
mulch. Permanent seeding mixtures shall be applied as shown on the vegetation plan. Temporary seeding shall be applied in all areas
susceptible to erosion (i.e. disturbed ditch banks, steep slopes, and spoil areas) such that ground cover is established within 21 working days
following completion of any phase of grading. Permanent ground cover shall be established for all disturbed areas within 15 working days
or 90 calendar days (whichever is shorter) following completion of construction. All areas should be seeded and mulched before leaving the
project reach. All waste material must be removed from the project reach.
16. Prior to seeding and mulching the haul road, the new cart path shall be built as shown on the plans and in the details.
17. The Contractor shall plant woody vegetation according to planting details and specifications. They should complete the reforestation phase
of the project and apply permanent seeding at the appropriate time of the year.
18. The Contractor shall ensure that the reach is free of trash and leftover materials prior to demobilization of equipment from the site.
