Re: North Carolina DWQ PCN Submittal - Hillsdale Forest Sewer Extension Project
DWQ Project # 05-0678
Dear Ms. Karoly,
On June 13, 2005, the Town of Cary (TOC) received your Request for More
Information concerning DWQ Project # 05-0678, Hillsdale Forest Sewer Extension
Project. Please find five copies of the altered North Carolina DWQ PCN, dated June
15, 2005, enclosed.
In response to the 3 items listed, the following comments have been added to the
North Carolina DWQ PCN:
1. The maintenance corridor is 20-feet wide, which is the Town's required
standard easement width. Since the crossing is less than 20-feet, this should
be allowable, and require no mitigation. The easement will be mowed yearly,
with sapling removal as needed. The sapling removal is conducted by hand to
minimize disturbance.
2. 1 have included as Attachment A-3, a copy of the TOC's SECTION 16000 -
SOIL EROSION AND SEDIMENTATION CONTROL, from our Technical
Specifications, which is part of all TOC Construction Project contracts, and will
be adhered to on this project. This section of the Technical Specifications fully
explains the re-vegetation plan which will be implemented. In the areas
considered wetland, a wetland grass mixture will be planted instead of the
standard mixtures.
3. The NW-12 has been approved by the USACOE. There are 3,500-square-feet
of wetland impacts associated with the installation of this sewer main. This
was calculated using the easement width of 20-feet and the length of the
sewer main between the tie-in at Existing Manhole "B" at Station 10+00 and
the toe of the slope located at station 11+75, which is 175-feet. The 3,500-

square-feet of disturbance calculates to 0.08 acres, which is below the 0.10
acres of disturbance which requires mitigation. Also, there will be no filling in
the affected area and the surface will be restored to its approximate original
contour.
I want to thank Ms. Edwards for discussing this project with me over the phone and
helping me find a solution to the DWQ's concerns. The Town of Cary and the
residents of the Hillsdale Forest neighborhood will be glad to see this project under
construction.
If you have any questions or need any other information concerning this project,
please contact me at 919-469-4335 or at larrod.buchanan(a)townofcary.org.

REQUEST FOR MORE INFORMATION
Dear Sir or Madam:
On April 21, 2005, the Division of Water Quality (DWQ) received your application dated April 13, 2005
to impact 40 feet of stream and 2,342 square feet (ft) of protected riparian buffers to construct the
proposed sewer line extension. The DWQ has determined that your application was incomplete and/or
provided inaccurate information as discussed below. The DWQ will require additional information in
order to process your application to impact protected wetland, streams and/or buffers on the subject
property. Therefore, unless we receive the additional infonnation requested below, we will have to move
toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8) and will place
this project on hold as incomplete until we receive this additional information. Please provide five copies
of the following information so that we may continue to review your project.
Additional Information Requested:
1. You have proposed mitigation for the two, 20' stream crossings. According to the Riparian Buffer
Rules, mitigation is required for perpendicular non-electric utility line when the crossing is between
40' and 150' (per crossing) and the maintenance corridor is greater than 10'. Additionally, you
have not stated how wide the permanent maintenance corridor is to be, please provide this
information so the DWQ can determine if mitigation is required.
2. Please provide a re-vegetation plan for the two, 20' temporary crossings.
3. The two streams that are being proposed to be impacted are within 50' of each other and the USGS
topographic map shows this to be a low lying, flat area. Additionally, the soils are mapped as
Worsham SL, which is a hydric soil. Please provide information as to whether a jurisdictional
determination for wetlands has been done for this site.
Please respond within three weeks of the date of this letter by sending this information to me in writing
and Eric Kulz of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we
will assume that you no longer want to pursue this project and we will consider the project as withdrawn.

financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The Town of Cary is installing a sanitary sewer main to improve the public health of the
residents in the Hillsdale Forest Subdivision. Many of these residents have failing septic systems
that require a high level of maintenance to keep them from releasing raw sewage. The trench in
which the sewer main will be placed will be as narrow as possible. Also, silt fence will be
placed on the up and downhill sides of the construction corridor and rock check dams will be
installed to keen the transportation of solids to a minimum. The crossing installation will be
done during low-flow periods to cause the least impact
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http:/ih2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
N/A
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wm/index.litm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the

wastewater generated from the proposed project, or available capacity of the subject facility.
This waste water will flow to the South Cary WWTP. The Plant, rated at 12.8 mgd with over 5
mud of excess capacity, has more than enough excess capacity to cover the additional 12,320
gallons per day proposed under this project. The Plant discharges into Middle Creek and uses
the following processes to treat the influent flow: bar screens, grit removal facilities, three
aeration basins, four secondary clarifiers, seven deep-bed tertiary filters, ultraviolet disinfection,
and a cascade aerator for reaeration prior to discharge.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application?
Yes ? No
XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
The Town of CM is installing this project at its earliest convenience for two reasons. First,
several of the properties have failing septic systems which are an environmental concern.
Second, several of the properties have shallow water wells with poor quality water.

Project No: SW 5002 16000-6 Hillsdale Forest Sewer Extension Project
PART 4 - PERMANENT LAWN SEEDING MEASURES
A. General
The following information shall be applicable for all permanent lawn
seeding. Permanent lawn seeding shall take place within all developed
areas of disturbance including residential and commercial areas and
shall be replaced in kind of existing material by the Contractor. An
approved turf type tall fescue blend shall be used per the Contract
Documents. Kentucky 31 is not an acceptable blend.
ii. When seeding must take place out of season for permanent grass the
appropriate temporary seeding shall be done and the contractor shall be
responsible for permanent seeding as specified in season at no
additional cost to Owner.
iii. Contractor shall be responsible for lawn maintenance through
substantial completion. Lawns must be at 90% coverage at substantial
completion review to be accepted. If not at 90% coverage, substantial
completion will be delayed until the following growing season.
B. Site Preparation:
Remove or kill any undesirable existing turf or vegetation. Herbicide
spraying or other chemical treatment shall be approved by the Engineer
prior to being used by the contractor. If preexisting turf or other
vegetation is mixed with the soil to be reused, the contractor shall use
best judgement in removing it or incorporating it into the soil during
preparation.
ii. If topsoil was not used to reestablish the upper soil layer and the upper
soil is heavy with high clay content, spread 1.5-2 inches of aged ground
pine bark or bagged organic humus over the area to be repaired.
iii. For all grasses except centipedegrass, apply per 1,000 square feet:
75 pounds of ground limestone and one of the following fertilizers:
40 pounds of 5-10-10; 20 pounds of 10-20-20; or 20 pounds of 8-8-8
or 10-10-10 in combination with 4 pounds of 0-46-0. Centipedegrass
prefers acidic soils and low levels of phosphorus and may not require the
addition of lime and phosphorus.
Project No: SW 5002 16000-7 Hillsdale Forest Sewer Extension Project
iv. Incorporate lime and fertilizer (and pine bark if added) into the top 6
inches of the soil using a rototiller or by hand. Rototill or hand cultivate
to well incorporate the amendments and get a uniform loosely textured
soil of minimum 6-inch depth.
v. Rake or harrow the site to establish a smooth and level final grade. Soil
particles should be no larger than marble size, and pea gravel size is
even better. Hand raking to level the soil and work out hills and hollows.
For areas larger than 100 sq. ft. allow rain or irrigate to settle the soil. In
some situations, the Engineer may require rolling or cultipacking to firm
the soil before seeding. Hand rake again to break up the crusty surface
before seeding or planting.
C. Installation:
L General:
a) Seed or plant the required grass according to Table 3.
b) The choice of turfgrass type, variety and propagation form shall be
specified in the Contract Documents, as specified in the Itemized
Proposal, or as designated by the Engineer.
c) Seed shall be tagged certified seed. Germination shall be a
minimum of 95%. Seed shall be 98% pure with less than 2% other-
crop seed or debris. Seed shall be free of noxious weed seed.
d) Sod, sprigs, plugs of
shall be certified free
health and vigor, free

Engineer or Inspector of each day's
a) Sow the seed on freshly prepared soil. Ensure uniform coverage by
using a centrifugal (rotary) or drop-type spreader. Areas larger than
100 sq. ft. shall be seeded with a minimum of two passes at the
appropriate partial rate for each pass. For areas averaging greater
Project No: SW 5002 16000-8 Hillsdale Forest Sewer Extension Project
15 ft. width, apply half the seed in one direction and the other half at
right angles to the first direction.
b) Apply a starter-type fertilizer to the soil surface for example, 10
pounds of 5-10-10 or 5 pounds of 10-20-20 per 1,000 square feet at
the time of seeding.
c) Lightly cover the seed by hand raking or dragging with a mat or
chain-link fence. Roll or tamp the soil lightly to firm the surface and
provide good seed-to-soil contact.
d) Mulch grass seed with weed-free small grain straw or hay. Use one
bale per 1,000 square feet for warm-season grasses and 1 to 2 bales
for cool-season grasses. Stabilize small areas of mulch by rolling,
watering or tacking with asphalt tacking spray. Twine netting can be
used if wind displacement is a problem. If applied evenly and lightly,
these materials need not be removed. Larger areas shall be
stabilized by asphalt tacking spray or twine netting.
ii. Sprigging or Broadcasting:
a) Sprigging is the preferred method of installing bermudagrass in larger
areas. For smaller areas of bermudagrass, sprigging and plugging
are both good options. The less expensive is preferred. In some
cases sod may be less expensive or necessary due to
circumstances.
b) Broadcasting sprigs uniformly over the entire area. Bermudagrass or
zoysiagrass sprigs shall be broadcast at a minimum rate of 5 bushels
(yards) of sprigs per 1,000 square feet. Up to 10 bushels (yards)
may be used where very fast cover is desired. Press the sprigs into
the top Y2 to 1 inch of soil by hand, and then by using an old disk, set
straight. In the case of very large areas use a sprigging machine,
cultipacker, or roller. (Note - St. Augustinegrass is seldom
established through broadcasting because the stems are too
sensitive.)
iii. Plugging:
a) Plugging is the preferred method of installing zoysia and St.
Augustine except where sprigging or sod is less expensive or
necessary due to circumstances.
b) Plugs shall consist of individual pieces of sod that are 2 inches or
larger. The plugs shall be planted at grade on 8 inch centers.
Project No: SW 5002 16000-9 Hillsdale Forest Sewer Extension Project
iv. Soddinq:
a) Lay sod as soon as possible after it has been harvested to prevent
injury. Sod should be installed within 24 hours of delivery. While
installing, take action as necessary to prevent heat buildup within the
unlaid sod. Plan to unstack and unroll the sod if it cannot be laid
within 48 hours. Soil should be moist (but not overly wet) before
laying sod. Irrigating the soil several days before delivery is often
adequate.
b) Start sodding from a straight edge (driveway or sidewalk) and butt
strips together, staggering them in a brick-like pattern. Avoid
stretching sod. Use a knife or sharp spade for trimming to fit
irregularly shaped areas. Lay sod lengthwise across the face of
slopes and peg or stake the pieces to prevent slippage. After the sod
has been placed, roll the lawn to ensure good sod-to-soil contact.
c) Water sod immediately after installation. Soak sod thoroughly
enough to penetrate soil below the newly installed sod to a minimum
depth of two (2) inches. Contractor is responsible for insuring
adequacy of water supply. The Contractor shall provided any
necessary temporary means to properly water sod, including
temporary pumps and sprinklers. Proper irrigation shall be required
by the contractor until the project has been inspected and is accepted
by the Town of Cary. (The Contractor shall be required to obtain all
applicable watering permits from the Town of Cary prior to beginning
watering activities.)
d) In some cases sod can be laid in space planting "semi-checkerboard"
fashion in order to lower costs. This method is described here
assuming that the sod is cut into the standard 18 in. x 24 in. size.
The first piece of sod is laid with the narrow side flush to a straight
edge. This will start a row that is 24 in. wide. The next piece of sod
is laid likewise but it is spaced 9 in. away and parallel to the first
piece along the longer side. This is continued to make the first row.
The next row is laid flush with the previous and in the same fashion
except it laid offset by 9 inches, i.e. laid beginning at the centerline of
the first piece of sod in the previous row. Subsequent rows are laid in
this alternating pattern.
D. Cleanup and Inspection:
i. Upon completion of work, the Contractor shall remove from the site all
equipment and other articles used. All excess soil, stone, and debris
shall be removed and legally disposed of at no additional cost to the
Owner. All work areas shall be left in a clean and neat condition. All
Project No: SW 5002 16000-10 Hillsdale Forest Sewer Extension Project
damage to existing construction caused by landscaping operations shall
be repaired to the satisfaction of the Town at the Contractor's expense.
ii. Seeded areas shall be protected and replanted as necessary to
establish a uniform stand of specified grass. Scattered bare spots, none
of which shall be larger that one (1) square foot, will be allowed up to a
maximum of 3% of the seeded area for each property. When seeded
areas are ready for inspection, the maintained turf areas shall be neatly
mowed to the uniform height of approximately two and one-half (2.5)
inches. The lawns shall be considered established only when the
specified grass is vigorous and growing well in addition to meeting the
other requirements specified.
iii. An inspection of the completed seeding shall be made at the conclusion
of the landscape work upon written notice requesting such inspection
submitted by the Contractor to the Engineer, at least ten (10) days prior
to the anticipated date of inspection.
iv. A final inspection shall be performed when a satisfactory stand of
seeded turf grass has been produced, upon written notice requesting
such inspection submitted by the Contractor to the Engineer, at least ten
(10) days prior to the anticipated date of inspection. If a satisfactory
stand of turf has not been produced at the time of final inspection,
necessary repairs shall be performed in conformance with the
requirements of this section. Upon completion of these repairs, the
seeded grass shall be reinspected upon written notice as above.
E. Basis of Payment:
Payment for establishing permanent lawn ground cover shall be the
actual amount of seeding installed and will be paid for at the unit price
bid per acre or square yard as indicated on the Itemized Proposal in the
contract documents for "Permanent Lawn Seeding and Mulching." This
price shall be full compensation for all work covered by this section
including but not limited to furnishing all permanent and temporary
seeding, mulching, fertilizing, tacking, watering, site preparation,
cleanup, maintenance, and warranty of work as specified.
ii. Distribution of Billing and Payments for "Permanent Lawn Seeding and
Mulching" shall be made as follows:
a) Fifty percent (50%) of the total quantity of the seeding and mulching
items on the Itemized Proposal on the first partial payment estimate
after which the initial seeding has been completed and accepted.
Project No: SW 5002 16000-11 Hillsdale Forest Sewer Extension Project

of denuded areas. The above vegetation rates are those, which do well under local
conditions; other seeding rate combinations may be possible but must be approved by
the Engineer.
***Temporary - Reseed according to optimum season for desired permanent
vegetation. Do not allow temporary cover to grow over 12 inches in height before
mowing to keep fescue from being shaded out.
Project No: SW 5002 16000-6 Hillsdale Forest Sewer Extension Project
PART 4 - PERMANENT LAWN SEEDING MEASURES
A. General
i. The following information shall be applicable for all permanent lawn
seeding. Permanent lawn seeding shall take place within all developed
areas of disturbance including residential and commercial areas and
shall be replaced in kind of existing material by the Contractor. An
approved turf type tall fescue blend shall be used per the Contract
Documents. Kentucky 31 is not an acceptable blend.
When seeding must take place out of season for permanent grass the
appropriate temporary seeding shall be done and the contractor shall be
responsible for permanent seeding as specified in season at no
additional cost to Owner.
iii. Contractor shall be responsible for lawn maintenance through
substantial completion. Lawns must be at 90% coverage at substantial
completion review to be accepted. If not at 90% coverage, substantial
completion will be delayed until the following growing season.
B. Site Preparation:
Remove or kill any undesirable existing turf or vegetation. Herbicide
spraying or other chemical treatment shall be approved by the Engineer
prior to being used by the contractor. If preexisting turf or other
vegetation is mixed with the soil to be reused, the contractor shall use
best judgement in removing it or incorporating it into the soil during
preparation.
ii. If topsoil was not used to reestablish the upper soil layer and the upper
soil is heavy with high clay content, spread 1.5-2 inches of aged ground
pine bark or bagged organic humus over the area to be repaired.
iii. For all grasses except centipedegrass, apply per 1,000 square feet:
75 pounds of ground limestone and one of the following fertilizers:
40 pounds of 5-10-10; 20 pounds of 10-20-20; or 20 pounds of 8-8-8
or 10-10-10 in combination with 4 pounds of 046-0. Centipedegrass
prefers acidic soils and low levels of phosphorus and may not require the
addition of lime and phosphorus.
Project No: SW 5002 16000-7 Hillsdale Forest Sewer Extension Project
iv. Incorporate lime and fertilizer (and pine bark if added) into the top 6
inches of the soil using a rototiller or by hand. Rototill or hand cultivate
to well incorporate the amendments and get a uniform loosely textured
soil of minimum 6-inch depth.
v. Rake or harrow the site to establish a smooth and level final grade. Soil
particles should be no larger than marble size, and pea gravel size is
even better. Hand raking to level the soil and work out hills and hollows.
For areas larger than 100 sq. ft. allow rain or irrigate to settle the soil. In
some situations, the Engineer may require rolling or cultipacking to firm
the soil before seeding. Hand rake again to break up the crusty surface
before seeding or planting.
C. Installation:
L General:
a) Seed or plant the required grass according to Table 3.
b) The choice of turfgrass type, variety and propagation form shall be
specified in the Contract Documents, as specified in the Itemized
Proposal, or as designated by the Engineer.
c) Seed shall be tagged certified seed. Germination shall be a
minimum of 95%. Seed shall be 98% pure with less than 2% other-
crop seed or debris. Seed shall be free of noxious weed seed.
d) Sod, sprigs, plugs o
shall be certified free
health and vigor, freE
adverse temperature,
that are older than
condition.
other vegetative plant propagation materials
of noxious weeds. Materials shall be in good
of disease or pests, or damage from dryness,
herbicides, fertilizer or other chemicals. Sprigs
48 hours are not acceptable regardless of
e) The Contractor shall maintain a log of dates that sod, sprigs, plugs,
or other seeding installation was completed for each individual
property and shall notify the Engineer or Inspector of each day's
progress.
ii. Seeding:
a) Sow the seed on freshly prepared soil. Ensure uniform coverage by
using a centrifugal (rotary) or drop-type spreader. Areas larger than
100 sq. ft. shall be seeded with a minimum of two passes at the
appropriate partial rate for each pass. For areas averaging greater
Project No: SW 5002 16000-8 Hillsdale Forest Sewer Extension Project
15 ft. width, apply half the seed in one direction and the other half at
right angles to the first direction.
b) Apply a starter-type fertilizer to the soil surface for example, 10
pounds of 5-10-10 or 5 pounds of 10-20-20 per 1,000 square feet at
the time of seeding.
c) Lightly cover the seed by hand raking or dragging with a mat or
chain-link fence. Roll or tamp the soil lightly to firm the surface and
provide good seed-to-soil contact.
d) Mulch grass seed with weed-free small grain straw or hay. Use one
bale per 1,000 square feet for warm-season grasses and 1 to 2 bales
for cool-season grasses. Stabilize small areas of mulch by rolling,
watering or tacking with asphalt tacking spray. Twine netting can be
used if wind displacement is a problem. If applied evenly and lightly,
these materials need not be removed. Larger areas shall be
stabilized by asphalt tacking spray or twine netting.
ii. Sprigging or Broadcasting:
a) Sprigging is the preferred method of installing bermudagrass in larger
areas. For smaller areas of bermudagrass, sprigging and plugging
are both good options. The less expensive is preferred. In some
cases sod may be less expensive or necessary due to
circumstances.
b) Broadcasting sprigs uniformly over the entire area. Bermudagrass or
zoysiagrass sprigs shall be broadcast at a minimum rate of 5 bushels
(yards) of sprigs per 1,000 square feet. Up to 10 bushels (yards)
may be used where very fast cover is desired. Press the sprigs into
the top Y2 to 1 inch of soil by hand, and then by using an old disk, set
straight. In the case of very large areas use a sprigging machine,
cultipacker, or roller. (Note - St. Augustinegrass is seldom
established through broadcasting because the stems are too
sensitive.)
iii. Plugging:
a) Plugging is the preferred method of installing zoysia and St.
Augustine except where sprigging or sod is less expensive or
necessary due to circumstances.
b) Plugs shall consist of individual pieces of sod that are 2 inches or
larger. The plugs shall be planted at grade on 8 inch centers.
Project No: SW 5002 16000-9 Hillsdale Forest Sewer Extension Project
iv. Sodding:
a) Lay sod as soon as possible after it has been harvested to prevent
injury. Sod should be installed within 24 hours of delivery. While
installing, take action as necessary to prevent heat buildup within the
unlaid sod. Plan to unstack and unroll the sod if it cannot be laid
within 48 hours. Soil should be moist (but not overly wet) before
laying sod. Irrigating the soil several days before delivery is often
adequate.
b) Start sodding from a straight edge (driveway or sidewalk) and butt
strips together, staggering them in a brick-like pattern. Avoid
stretching sod. Use a knife or sharp spade for trimming to fit
irregularly shaped areas. Lay sod lengthwise across the face of
slopes and peg or stake the pieces to prevent slippage. After the sod
has been placed, roll the lawn to ensure good sod-to-soil contact.
c) Water sod immediately after installation. Soak sod thoroughly
enough to penetrate soil below the newly installed sod to a minimum
depth of two (2) inches. Contractor is responsible for insuring
adequacy of water supply. The Contractor shall provided any
necessary temporary means to properly water sod, including
temporary pumps and sprinklers. Proper irrigation shall be required
by the contractor until the project has been inspected and is accepted
by the Town of Cary. (The Contractor shall be required to obtain all
applicable watering permits from the Town of Cary prior to beginning
watering activities.)
d) In some cases sod can be laid in space planting "semi-checkerboard"
fashion in order to lower costs. This method is described here
assuming that the sod is cut into the standard 18 in. x 24 in. size.
The first piece of sod is laid with the narrow side flush to a straight
edge. This will start a row that is 24 in. wide. The next piece of sod
is laid likewise but it is spaced 9 in. away and parallel to the first
piece along the longer side. This is continued to make the first row.
The next row is laid flush with the previous and in the same fashion
except it laid offset by 9 inches, i.e. laid beginning at the centerline of
the first piece of sod in the previous row. Subsequent rows are laid in
this alternating pattern.
D. Cleanup and Inspection:
i. Upon completion of work, the Contractor shall remove from the site all
equipment and other articles used. All excess soil, stone, and debris
shall be removed and legally disposed of at no additional cost to the
Owner. All work areas shall be left in a clean and neat condition. All
Project No: SW 5002 16000-10 Hillsdale Forest Sewer Extension Project
damage to existing construction caused by landscaping operations shall
be repaired to the satisfaction of the Town at the Contractor's expense.
ii. Seeded areas shall be protected and replanted as necessary to
establish a uniform stand of specified grass. Scattered bare spots, none
of which shall be larger that one (1) square foot, will be allowed up to a
maximum of 3% of the seeded area for each property. When seeded
areas are ready for inspection, the maintained turf areas shall be neatly
mowed to the uniform height of approximately two and one-half (2.5)
inches. The lawns shall be considered established only when the
specified grass is vigorous and growing well in addition to meeting the
other requirements specified.
iii. An inspection of the completed seeding shall be made at the conclusion
of the landscape work upon written notice requesting such inspection
submitted by the Contractor to the Engineer, at least ten (10) days prior
to the anticipated date of inspection.
iv. A final inspection shall be performed when a satisfactory stand of
seeded turf grass has been produced, upon written notice requesting
such inspection submitted by the Contractor to the Engineer, at least ten
(10) days prior to the anticipated date of inspection. If a satisfactory
stand of turf has not been produced at the time of final inspection,
necessary repairs shall be performed in conformance with the
requirements of this section. Upon completion of these repairs, the
seeded grass shall be reinspected upon written notice as above.
E. Basis of Payment:
Payment for establishing permanent lawn ground cover shall be the
actual amount of seeding installed and will be paid for at the unit price
bid per acre or square yard as indicated on the Itemized Proposal in the
contract documents for "Permanent Lawn Seeding and Mulching." This
price shall be full compensation for all work covered by this section
including but not limited to furnishing all permanent and temporary
seeding, mulching, fertilizing, tacking, watering, site preparation,
cleanup, maintenance, and warranty of work as specified.
ii. Distribution of Billing and Payments for "Permanent Lawn Seeding and
Mulching" shall be made as follows:
a) Fifty percent (50%) of the total quantity of the seeding and mulching
items on the Itemized Proposal on the first partial payment estimate
after which the initial seeding has been completed and accepted.
Project No: SW 5002 16000-11 Hillsdale Forest Sewer Extension Project
b) Twenty-five percent (25%) of the total quantity of the seeding and
mulching items on the Itemized Proposal on the first partial payment
estimate made after which the initial establishment of grass and any
required reseeding is complete.
c) Twenty-five percent (25%) of the total quantity of the seeding and
mulching items on the Itemized Proposal on the first partial payment
after the final establishment of grass and the project is one hundred
percent (100%) complete.

REQUEST FOR MORE INFORMATION
Dear Sir or Madam:
On April 21, 2005, the Division of Water Quality (DWQ) received your application dated April 13, 2005
to impact 40 feet of stream and 2,342 square feet (ft) of protected riparian buffers to construct the
proposed sewer line extension. The DWQ has determined that your application was incomplete and/or
provided inaccurate information as discussed below. The DWQ will require additional information in
order to process your application to impact protected wetland, streams and/or buffers on the subject
property. Therefore, unless we receive the additional information requested below, we will have to move
toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8) and will place
this project on hold as incomplete until we receive this additional information. Please provide five copies
of the following information so that we may continue to review your project.
Additional Information Requested:
1. You have proposed mitigation for the two, 20' stream crossings. According to the Riparian Buffer
Rules, mitigation is required for perpendicular non-electric utility line when the crossing is between
40' and 150' (per crossing) and the maintenance corridor is greater than 10'. Additionally, you
have not stated how wide the permanent maintenance corridor is to be, please provide this
information so the DWQ can determine if mitigation is required.
2. Please provide a re-vegetation plan for the two, 20' temporary crossings.
3. The two streams that are being proposed to be impacted are within 50' of each other and the USGS
topographic map shows this to be a low lying, flat area. Additionally, the soils are mapped as
Worsham SL, which is a hydric soil. Please provide information as to whether a jurisdictional
determination for wetlands has been done for this site.
Please respond within three weeks of the date of this letter by sending this information to me in writing
and Eric Kulz of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we
will assume that you no longer want to pursue this project and we will consider the project as withdrawn.

financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The Town of Cary is installing a sanitary sewer main to improve the public health of the
residents in the Hillsdale Forest Subdivision. Many of these residents have failing septic systems
that require a high level of maintenance to keep them from releasing raw sewage. The trench in
which the sewer main will be placed will be as narrow as possible. Also, silt fence will be
placed on the up and downhill sides of the construction corridor and rock check dams will be
installed to keep the transportation of solids to a minimum. The crossing installation will be
done during low-flow periods to cause the least impact
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 9 of 12

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http:/ih2o.enr.state.nc.us/ncwctlands/stn-ngide.htin].
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
N/A
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wi-p/indox.litm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
