VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated .with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: There will be one stream
crossing that crosses an unimportant stream. with a 50' Neuse Buffer. There will be stream
and buffer impacts associated with this crossing. An existin fg arm pond on the site is
• scheduled to be retrofit in order to refurbish the dam, provide aesthetic value and provide
Updated 11/1/2005

detention Note that while the pond will be retrofit as an exempt use design of the retrofit
will be conducted such that the normal pool of the pond remains the same as in the existing
condition This will eliminate an~mpacts to the wetland aspect of the existing pond.
Sanitary sewer installation will require impacts to Zone 1 and Zone 2 of the Neuse buffer and
a stream crossing associated with the sanitary sewer will be required.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
fmancial 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. This proiect is a `cluster'

. and significant dedicated open space has been provided and steep slopes have been identified and
avoided. In order to construct the project, one stream crossin ig s required. However, the stream
crossin,; has been designed such that it is as far upstream as possible on the site. Another
crossing was previouslyproposed, but this crossing has been eliminated by relocating the
crossing upstream of the channel. The remaining crossing will impact an `unimportant' stream as
classified by US Army Corps. A small portion of an existing wetland will also be impacted in
order to provide access to the site. However certain areas of identified wetlands are avoided by
designing the site such that no lots are located on the wetlands. A small wetland will require
filling in order to viablygrade an adjacent lot. Sanitary sewer is required to construct the
project. The sanitary sewer line has been located such that it avoids Zone 1 of the Neuse Buffer
to the extent possible. Some impacts will occur in Zone 2, and this is necessary in order to
achieve rg avity flow from the lots on the site. Impact of the stream at the sanitary sewer crossin
will be avoided with a `jack and bore' method. The stream at this crossing will therefore remain
undisturbed. There is an existing farm pond' on the site, which will be retrofit. Retrofitting of
the pond falls under maintenance and repair of existin fg arm ponds and is an allowable use, and
is exempt from mitigation requirements. The site plan, which is included with this application
shows the extension use of `clusterins;' to avoid ecolo ig rally and environmentally sensitive
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.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, 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 NCEEP 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 (see DWQ website for most current
version.).
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
Updated 11/1/2005
Page 10 of 13

. 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.
No perennial streams are impacted resulting from construction of this project. Wetland
disturbance is held below 1/lOt" acre and buffer impacts are minimized to stream crossm~s
and provision of sanitary sewer for the single-family homes.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http~//www ncee~ net/panes/inlieureplace.htm. If use of the NCEEP is proposed,

THE MEADOWS AT TWIN LAKES
PRE-CONSTRUCTION NOTIFICATION
General Description
Junction Road Property is a proposed single-family, cluster subdivision.
The 77.63 acre property is located southeast of Junction Road, south of
the intersection of Junction Road and Cheek Road in Durham, North
Carolina. Phase I of the project consists of 53.56 acres. The project is
located in the F/J-B watershed protection district and the Neuse River
Basin. 85% TSS removal is not required because the total impervious area
is not to exceed 24~. This narrative and accompanying permit
application and supporting calculations and data is an application for a
Nationwide Permit 29.
Wetland Impacts
Approximately 0.94 acre of forested wetland is currently present on the
• site. The proposed wetland fill/disturbance is 0.085 acre. This area is lower
than the maximum threshold of 0.10 acre for the purpose of requiring a
404 permit.
Stream Impacts
One road crossing is proposed for this project. The crossing has been
carefully considered to impact the least environmentally sensitive waters
while continuing to allow the project to be viable. One stream impact is
eliminated by altering the path of the road. Additionally, the culvert is
sized and will be constructed such that it is 'buried' per the NC DWQ
requirement allowing for aquatic life passage. The size of the velocity
dissipater is designed to minimize the length of the dissipater while
maintaining the ability of the dissipater to function appropriately. The
result is a minimization of stream impact due to the dissipater.
The total stream impact due to the road crossing is 122 If. Note that the
stream is considered `unimportant' by US Army Corps and it is not
perennial at the location of the crossings. For this reason, mitigation
associated with stream impacts is not required.
•

• A sanitary sewer crossing is proposed in order to tie the sewer to an
existing line. This impact will be limited to 25 If. The total stream impact is
therefore 147 If.
Neuse Buffer Impacts
Neuse buffer impacts will occur with the road crossings and sanitary
sewer. The sanitary sewer layout must accept all of the homes on the site
with gravity flow. In order to provide gravity flow, and to minimize the
number of stream crossings, it is necessary in some cases to place the
sanitary sewer line in Zone 2 of the Neuse Buffer. This is done only when
absolutely necessary.
The total Zone 2 buffer impact, including sanitary sewer, is 12,640 sf. The
total Zone 1 impact is 10,767 sf and the total buffer impact is 23,407 sf. The
total buffer impacts proposed are lower than the threshold wherein
mitigation is required and mitigation is not required nor is it proposed.
Preliminary Level Spreader Design
11 level spreaders are proposed for this project. The storm drainage
• system is dispersed to the maximum extent possible to maximize sheet flow
through the buffered streams.
The level spreader designs are valid with the following rationale. There are
two basic situations for stream buffers on the site. One situation involves
construction of a grass filter strip and the other situation involves level
spreaders discharging into the 50-foot buffer with slopes greater than 6%.
The level spreaders with grass filter strips are designed by providing sheet
flow across an appropriate slope in an area that will remain undisturbed in
perpetuity. These undisturbed areas will be insured against disturbance
with language on the final plat. The rationale behind the level spreader
design in this situation is that the sheet flow will travel across appropriate
slopes before reaching the steep slopes areas. The effect will be that
nutrient removal will be provided as is intended by the Neuse Rules. The
relatively flat slopes will also server to minimize the formation of
concentrated flow prior to entry into each buffer and therefore minimize
the potential for any erosion.
The other scenario as described above is that situation in which the level
spreader discharge into a 50-foot buffer with slopes greater than 6% but
• less than 15~. In each of these situations, a level spreader in series is
proposed and a flat, grass filter strip is installed when feasible. The second

• level spreader in the case of Level Spreaders # 1, 9 and 10 will have a
second level spreader located in Zone 2 of the Neuse Buffer. Each of
these level spreaders will be non-structural and they will be lined with
appropriate material to stabilize the vegetation.
Level Spreader 4 has level spreader in series, but this level spreader is
located outside of the Neuse Buffer and a grass filter strip is provided
between the two level spreaders.
A summary of the preliminary level spreader designs is provided and an
executed Operations and Maintenance Agreement is provided with this
permit application.
Conclusion
A Nationwide 29 permit is required for the impacts resulting from this
project. Planning, design and construction of the site minimizes impacts
to the streams, wetland and buffers. No mitigation is required as a result
of the proposed impacts.

MAINTENANCE ACTIVITY FREQUENCY
Post-construction monitoring-inspect for vegetation, Check after every heavy rainfall for first 6 months
settlin ,erosion, or concentrated flow. followin construction.
Inspect Diverter Box and clean and/or make repairs. Once a month and after heavy rainfalls/storms.
Look for:
• Clogged inlet or outlet pipes.
• Trash/debris in the box.
Inspect Forebay + Level Spreader. Clean and/or Once a month and after heavy rainfalls/storms.
make repairs. Look for:
• Sediment in forebay and along level spreader
lip;
• Trash and/or leaf buildup.
• Scour, undercutting of level spreader.
• Settlement of level spreader structure (no

spreader).
• Fallen trees on level spreader.
• #57 stone washin downhill.
Inspect the Riparian Buffer and the Bypass Swale Once a month and after heavy rainfalls/storms.
and make repairs as needed'. Look for:
• Damaged turf reinforcement or riprap rolling
downhill.
• Erosion within the buffer or swale.
• Concentrated flows downhill of level
s reader-look for ullies or sediment flows.
Mow grass to a 6" height. As needed during growing season.
Remove any weeds/shrubs growing on level spreader Once a year.

Re: Detailed Wetlands Delineation and Neuse River Buffer Evaluation
Junction Road Site (+/- 80 acres)
Durham, Durham County
•
Dear Mr. Jernigan:
On Apri16, 2004, S&EC personnel conducted a detailed wetland delineation and Neuse River
Buffer evaluation on the Junction Road Site. The property is located on the eastern side of
Junction Road (SR 1838) approximately 5,000 feet northeast of the intersection of Highway 98
and Junction Road. Figure 1 shows the location of the site on a USGS topographic quadrangle.
EXECUTIVE SUMMARY
We have determined that wetlands and jurisdictional waters (i.e., streams and ponds) exist on the
site. The attached wetland sketch snap depicts the approximate location of wetlands and
jurisdictional waters identified during our evaluation. Please refer to the sketch map and the
results and recommendations section below for more detailed information.
SCOPE OF WORK
•
The detailed wetland delineation consisted of pedestrian reconnaissance of the property to
examine the soils, vegetation, and hydrology for the presence of areas that meet the criteria for
jurisdictional wetlands by the procedures described in the Corers of Engineers Wetlands
Delineation Manual (January 1987 -Final Report). Areas on the site with positive indicators of
hydric soils and evidence of wetland hydrology and hydrophytic vegetation were flagged with
sequentially numbered, pink S&EC logo flagging. Proof of wetland hydrology would be the

existence of hydric soils with oxidized root channels in the upper 12 inches of the soil profile,
water borne deposits, drift lines, scour marks, drainage patterns, regional indicators of soil
saturation, etc. Surface waters such as intermittent and perennial stream channels, ponds, and
lakes, which are also subject to regulation by the US Army Corps of Engineers (USAGE) as
waters of the US, were also identified. These surface waters may also be referred to as
jurisdictional waters to indicate that they are within the jurisdiction of the USAGE. It is
important to note that wetlands are also classified as waters of the US and regulated by the
USAGE.
Wetland areas located entirely within Zone 1 of the Neuse River riparian buffer were not
flagged (see below for more information regarding riparian buffers). If impacts to Zone 1
of the riparian buffer are proposed, S&EC recommends that the client stake the centerline
and/or limits of the impact area for S&EC to delineate wetlands within the area of impact
only.
The Neuse River Basin• Nutrient Sensitive Waters Management Strategy: Protection and
Maintenance of Riparian Areas with Existing Forest Vegetation (15A NCAC 2B.0233) rules
apply to 50-foot wide riparian buffers directly adjacent to surface waters in the Neuse River
Basin (intermittent streams, perennial streams, lakes, ponds, and estuaries), excluding wetlands.
The rule defines surface waters as features approximately shown on either the most recent
version of the soil survey map prepared by the Natural Resource Conservation Service (NRCS)
of the US Department of Agriculture (USDA) or the 7.5-minute quadrangle topographic maps
prepared by the US Geologic Survey (USGS). Surface waters that appear on these snaps are not
subject only if an on-site determination by the NC Division of Water Quality (NC-DWQ) shows
that they fall into one of the following categories:
1) Ditches and manmade conveyances other than modified natural streams;
2) Manmade ponds and lakes that are located outside natural drainage ways; or
3) Ephemeral (stormwater) streams.
S&EC's Neuse River buffer evaluation consisted of examining each feature on the site that is
shown on the most recent version of the pertinent topographic map or soil survey for
applicability to the Neuse River Basin riparian buffer rule using NC-DWQ stream evaluation
techniques. Figure 2 shows the location of the site on the relevant Durham County Soil Survey
map.
RESULTS & RECOMMENDATIONS
The results of the detailed delineation of jurisdictional wetlands and other waters of the US and
the evaluation of surface waters on the site subject or potentially subject to the Neuse River
Basin riparian buffer rule are discussed below.

Wetlands and Jurisdictional Waters:
We have determined that wetlands and jurisdictional waters (i.e., streams, ponds, or lakes) exist
on the site. The wetland sketch map depicts the approximate location of wetlands and
jurisdictional waters identified within the evaluated area. Jurisdictional waters on-site consist of
Feature A (an intermittent channel beginning at and below flag SO1), Feature B (an intermittent
channel beginning at the northern property line), Feature C (an intermittent channel below flag
S03), Feature D (a jurisdictional pond), Feature E (an intermittent channel beginning at and
below flag S04) and Feature G (beginning at and below flag SOS). Feature D was a drained pond;
however recent beaver activity has impounded the pond. Therefore the pond remains
jurisdictional and should be surveyed at the waters edge. Features on this site carry a water
quality classification of WS-IV; NSW (See water supply rules below).
Wetlands on-site consist of an emergent wetland/drained pond delineated with flags 100-114A
and 116B, a bottomland forest wetland delineated with flags 119A-129A and 119B-126B, a
bottomland forest wetland delineated with flags 200-208, a beaver impoundment delineated with
flags 300-321A and 322B, a beaver impoundment delineated with flags 322A and 323B-325A
and 330B, a bottomland forest wetland delineated with flags 411 A and B-416A and 414B and a
bottomland forest wetland delineated with flags 420 A and B-428 A and B.
• Two marginal areas exists on the property. Feature C contains a marginal stream/linear wetland
beginning at flag 502. Another marginal ephemeral stream/linear wetland exists above feature F
as indicated on the sketch map. S&EC does not believe these areas to be a jurisdictional
wetlands or waters, because these areas exhibit weak evidence of hydrophitic vegetation and
wetland hydrology. However due to the marginal nature of these areas, confirmation of our
determination should be obtained from the USACE. No other wetlands or jurisdictional waters
were found within the project boundaries.
All S&EC flags comprising the wetland and jurisdictional waters delineation should be surveyed
and a Wetland Delineation Map generated for use in USACE approval and permitting. Stream
channels in the field have not been flagged and should be surveyed with points taken at
bends and channel widths noted. The Wetland Delineation Map should include all of the
information listed on the attached `Requirements for Wetland Delineation Maps'. S&EC
delineation flag numbers should be shown on the wetland survey. Please have the property
owner complete the attached agent authorization form if you would like S&EC to act on their
behalf for requesting approval of the wetland delineation. This form will also be used in
preparing a permit application for impacts to wetlands or surface waters when we are provided
with a plan showing the proposed impacts. S&EC cannot conduct correspondence with the
USACE unless we have agent authorization (see attached Agent Authorization). This
authorization form must be filled out in its entirety by the current landowner and sent to

Neuse River Buffers:
The surface waters (i.e., intermittent streams, perennial streams, lakes, ponds or estuaries)
potentially subject to the 50-foot Neuse River Buffers include features A, B, C, D, E, F, G, H, the
impounded beaver pond, and the pond at the headwaters of feature A. No other surface waters are
indicated on either the USGS topographic or Durham County Soil Survey maps. S&EC believes
that Features A (below flag SO1), B (below northern property line), C (below flags S02 and S03),
D (below flags 321A and 322B), E (below flag S04), F (below flag SOS), and the impounded
beaver pond are all subject to the Neuse River Riparian Buffers. However, the NC-DWQ must
confirm our determination regarding the subjectivity of the aforementioned channels in order for
our determination to be valid. Therefore, a site meeting with the NC-DWQ will most likely be
required. S&EC will schedule this meeting unless you advise otherwise.
REGULATIONS
Regulations that apply to jurisdictional wetlands and waters present on the site are discussed
below.
Neuse River Basin Riparian Buffer Rules
The Neuse River Basin riparian buffer rules, which came into effect on 7/22/97, protect up to ~0 feet from the edge
of existing "surface waters" (intermittent streams, perennial streams, lakes, ponds and estuaries) located within the
Neuse River Basin. The 50-foot buffer basically consists of two zones. Zone 1 is measured 30 feet landward from
the top bank of streams and intended to contain an undisturbed-forested area. Zone 2 is measured 20 feet from the
edge of the first zone and is intended to contain a vegetated buffer. A couple of notable points of the rules include
the following: the allowance of grading with re-vegetating within Zone 2 (the outer 20 feet) and the requirement of
mitigation for road crossings greater than 150 feet in width and utility lines running parallel and within the buffers.
Water Supply Waters Rules
Perennial streams within a classified water supply watershed require a 100-foot buffer for new development activities
with greater than 24 percent "built upon" area (i.e., percent covered by impervious or partially impervious cover) and
a 30-foot buffer for activities with less than 24 percent built upon area by the NC-DWQ. (These buffers are in
addition to the 50-foot Neuse River Buffers. The stricter of the two buffers applies to these stream channels.) Other
regulations may also apply.
Durham Development Ordinances
The Durham City-County Zoning Ordinances were revised and adopted on 6/21/99 to include the addition of
"Section 11, Natural Resources Protection Standards". These new standards include Floodplain Protection
Standards, Stream Buffer Protection Standards, Steep Slope Protection Standards, Wetland Protection Standards and
Durham Inventory Site Protection Standards. The Stream Buffer Protection Standards require a 30-foot buffer for
"intermittent streams" and a 50-foot buffer for "perennial streams" indicated on either the USGS quadrangle
topographic maps or USDA Soil Survey of Durham County Map and drain an area twenty-five (25) acres or greater.
The Wetlands Protection Standards require atwenty-five (25) foot buffer for retained wetlands that do not receive a
404 Permit issued by the USAGE or 401 Water Quality Certification issued by the NC-DWQ and are greater than 1
• acre in size. This buffer can be limited to ten (10) feet if the site employs construction management techniques that
provide at least a comparable level of protection for the wetland areas. Allowable activities within the buffers
include street crossings, utility crossings, passive recreation activities, clearing and re-vegetating for the purposes of

improving its pollutant removal efficiency, and stormwater control facilities and wetlands constructed for mitigation
purposes. Variances from these rules can be applied for through the Board of Adjustments. S&EC can discuss these
new ordinances with you or supply you with the web site address that will provide you with specific details
concerning the ordinances.
Wetland Permitting
Wetland impact permits are issued on aper-project basis as determined by the USACE. The USACE has determined
that impacts on parcels sub-divided from larger tracts are sometimes considered to be cumulative to existing impacts
for the large tract. If this is the case, then thresholds as discussed below may not apply and impacts to wetlands must
be considered in light of existing permits.
Preconstruction notification to the USACE and the NC-DWQ is not required for wetland impacts that meet the
general conditions of Nationwide Permit 39 and that impact less than 1/10 acre per project. Preconstruction
notification and approval by the USACE is required for wetland impacts that exceed 1/10 of an acre and /or an
stream channel impacts. Preconstruction notification and approval by the NC-DWQ is required for wetland
impacts that exceed 1/10 of an acre if the property is west of I-95 or 1/3 of an acre if the project is east of I-95.
Preconstruction notification and approval by the NC-DWQ is required for a~ stream channel impacts
within buffered basins (i.e. the Neuse, Tar-Pamlico, Randleman, and portions of the Catawba Basins) or for
cumulative stream impacts that exceed 1501inear feet in non-buffered basins. If development impacts exceed
the thresholds for notification and proposed impervious area for the project exceeds 30%, then stormwater treatment
to meet the pollutant removal design standard of 85% removal of total suspended solids (i.e., wet detention basins,
stormwater wetlands, bioretention areas, etc.) will likely be required by the NC-DWQ. The maximum permanent
impact allowed per project under the nationwide permits is 1/2 acre of wetland and/or 300 linear feet of USACE
important stream channel. Nationwide Permit 39 limits above-grade fills within 100-year floodplains specifically
prohibiting above-grade fill within the floodway. Additionally, Nationwide Permit 39 limits stream channelization
and relocation to streams with an average annual flow of less than 1 cfs.
Per project impacts to vegetated wetlands in excess of 1 acre or impacts to streams that contain "significant aquatic
function" in excess of 150 linear feet will most likely require mitigation by the NC-DWQ. The USACE may require
mitigation for any wetland/jurisdictional waters impacts. Actual mitigation requirements are typically determined on
a case by case basis. Wetland mitigation is a complex process that requires planning and monitoring. S&EC will
discuss mitigation issues with you if we believe your project may require mitigation.
Impacts to channels containing "significant aquatic function" in excess of the notification thresholds may require
mitigation. Channel mitigation is typically intended to replace lost significant aquatic functions and values.
Relocating channels is considered to be an adverse impact and typically results in mitigation within the new channel.
Therefore, this type of mitigation usually requires that meanders be created within constructed channels. Side-slopes
and beds be vegetated; rip-rap is discouraged.
A complete NC-DWQ 401 Water Quality Certification application for a Nationwide Perniit has a maximum 60-day
processing period. A complete USACE Nationwide Permit application has a 45-day processing period, while
Individual Permit applications submitted to the USACE have no maximum processing periods. The USACE
requires that all impacts to wetlands or Waters of the US, less than 1/10 acre, be reported to the USACE
within 30 days of the completion of construction.
Nationwide Permits can potentially be utilized if the project is designed to impact up to 1/2 acre of jurisdictional
wetlands or waters of the US including a maximum of 300 linear feet of important stream channel impact under
NWP 39. Cumulative impacts per project over these nationwide thresholds will require an individual pernut.
• Individual Permits require an analysis to determine that the proposed impact is the least environmentally damaging
practical alternative, typically require compensatory mitigation, notification to adjacent property owners, a public
notice, and may require a public hearing. All impacts greater than 1/10 acre require written justification.

Durham Inventory Site Protection Standards. The Stream Buffer Protection Standards require a 30-foot buffer for
"intermittent streams" and a 50-foot buffer for "perennial streams" indicated on either the USGS quadrangle
topographic maps or USDA Soil Survey of Durham County Map and drain an area twenty-five (25) acres or greater.

Wetland Pernuttin~
Wetland impact permits are issued on aper-project basis as determined by the USACE. The USACE has determined
that impacts on parcels sub-divided from larger tracts are sometimes considered to be cumulative to existing impacts
for the large tract. If this is the case, then thresholds as discussed below may not apply and impacts to wetlands must
be considered in light of existing permits.
Preconstruction notification to the USAGE and the NC-DWQ is not required for wetland impacts that meet the
general conditions of Nationwide Permit 39 and that impact less than 1/10 acre per project. Preconstruction
notification and approval by the USAGE is required for wetland impacts that exceed 1110 of an acre and /or an
stream channel impacts. Preconstruction notification and approval by the NC-DWQ is required for wetland
impacts that exceed 1/10 of an acre if the property is west of I-95 or 1/3 of an acre if the project is east of I-95.
Preconstruction notification and approval by the NC-DWQ is required for an stream channel impacts
within buffered basins (i.e. the Neuse, Tar-Pamlico, Randleman, and portions of the Catawba Basins) or for
cumulative stream impacts that exceed 150 linear feet in non-buffered basins. If development impacts exceed
the thresholds for notification and proposed impervious area for the project exceeds 30%, then stormwater treatment
to meet the pollutant removal design standard of 85% removal of total suspended solids (i.e., wet detention basins,
stormwater wetlands, bioretention areas, etc.) will likely be required by the NC-DWQ. The maximum pernlanent
impact allowed per project under the nationwide permits is 1/2 acre of wetland and/or 300 linear feet of USACE
important stream channel. Nationwide Permit 39 limits above-grade fills within 100-year floodplains specifically
prohibiting above-grade fill within the floodway. Additionally, Nationwide Permit 39 limits stream channelization
and relocation to streams with an average annual flow of less than lcfs.
Per project impacts to vegetated wetlands in excess of 1 acre or impacts to streams that contain "significant aquatrc
function" in excess of 150 linear feet will most likely require mitigation by the NC-DWQ. The USAGE may require
mitigation for any wetland/jurisdictional waters impacts. Actual mitigation requirements are typically determined on
a case by case basis. Wetland mitigation is a complex process that requires planning and monitoring. S&EC will
discuss mitigation issues with you if we believe your project may require mitigation.
Impacts to channels containing "significant aquatic function" in excess of the notification thresholds may require
mitigation. Channel mitigation is typically intended to replace lost significant aquatic functions and values.
Relocating channels is considered to be an adverse impact and typically results in mitigation within the new channel.
Therefore, this type of mitigation usually requires that meanders be created within constructed channels. Side-slopes
and beds be vegetated; rip-rap is discouraged.
A complete NC-DWQ 401 Water Quality Certification application for a Nationwide Permit has a maximum 60-day
processing period. A complete USAGE Nationwide Permit application has a 45-day processing period, while
Individual Permit applications submitted to the USAGE have no maximum processing periods. The USAGE
requires that all impacts to wetlands or Waters of the US, less than 1/10 acre, be reported to the USAGE
within 30 days of the completion of construction.
Nationwide Permits can potentially be utilized if the project is designed to impact up to 1/2 acre of jurisdictional
wetlands or waters of the US including a maximum of 300 linear feet of important stream channel impact under
NWP 39. Cumulative impacts per project over these nationwide thresholds will require an individual permit.
• Individual Permits require an analysis to determine that the proposed impact is the least environmentally damaging
practical alternative, typically require compensatory mitigation, notification to adjacent property owners, a public
notice, and may require a public hearing. All impacts greater than 1/10 acre require written justification.

Re: Detailed Wetlands Delineation and Neuse River Buffer Evaluation
Junction Road Site (+/- 80 acres)
Durham, Durham County
•
Dear Mr. Jernigan:
On April 6, 2004, S&EC personnel conducted a detailed wetland delineation and Neuse River
Buffer evaluation on the Junction Road Site. The property is located on the eastern side of
Junction Road (SR 1838) approximately 5,000 feet northeast of the intersection of Highway 98
and Junction Road. Figure 1 shows the location of the site on a USGS topographic quadrangle.
EXECUTIVE SUMMARY
We have determined that wetlands and jurisdictional waters (i.e., streams and ponds) exist on the
site. The attached wetland sketch map depicts the approximate location of wetlands and
jurisdictional waters identified during our evaluation. Please refer to the sketch map and the
results and recommendations section below for more detailed information.
SCOPE OF WORK
The detailed wetland delineation consisted of pedestrian reconnaissance of the property to
examine the soils, vegetation, and hydrology for the presence of areas that meet the criteria for
jurisdictional wetlands by the procedures described in the Corps of Engineers Wetlands
Delineation Manual (January 1987 -Final Report). Areas on the site with positive indicators of
hydric soils and evidence of wetland hydrology and hydrophytic vegetation were flagged with
sequentially numbered, pink S&EC logo flagging. Proof of wetland hydrology would be the

existence of hydric soils with oxidized root channels in the upper 12 inches of the soil profile,
water borne deposits, drift lines, scour marks, drainage patterns, regional indicators of soil
saturation, etc. Surface waters such as intermittent and perennial stream channels, ponds, and
lakes, which are also subject to regulation by the US Army Corps of Engineers (USAGE) as
waters of the US, were also identified. These surface waters may also be referred to as
jurisdictional waters to indicate that they are within the jurisdiction of the USAGE. It is
important to note that wetlands are also classified as waters of the US and regulated by the
USAGE.
Wetland areas located entirely within Zone 1 of the Neuse River riparian buffer were not
flagged (see below for more information regarding riparian buffers). If impacts to Zone 1
of the riparian buffer are proposed, S&EC recommends that the client stake the centerline
and/or limits of the impact area for S&EC to delineate wetlands within the area of impact
only.
The Neuse River Basin• Nutrient Sensitive Waters Management Strategy: Protection and
Maintenance of Riparian Areas with Existing Forest Vegetation (15A NCAC 2B.0233) rules
apply to 50-foot wide riparian buffers directly adjacent to surface waters in the Neuse River
Basin (intermittent streams, perennial streams, lakes, ponds, and estuaries), excluding wetlands.
The rule defines surface waters as features approximately shown on either the most recent
version of the soil survey map prepared by the Natural Resource Conservation Service (NRCS)
of the US Department of Agriculture (USDA) or the 7.5-minute quadrangle topographic maps
prepared by the US Geologic Survey (USGS). Surface waters that appear on these maps are not
subject only if an on-site determination by the NC Division of Water Quality (NC-DWQ) shows
that they fall into one of the following categories:
1) Ditches and manmade conveyances other than modified natural streams;
2) Manmade ponds and lakes that are located outside natural drainage ways; or
3) Ephemeral (stormwater) streams.
S&EC's Neuse River buffer evaluation consisted of examining each feature on the site that is
shown on the most recent version of the pertinent topographic map or soil survey for
applicability to the Neuse River Basin riparian buffer rule using NC-DWQ stream evaluation
techniques. Figure 2 shows the location of the site on the relevant Durham County Soil Survey
map.
RESULTS & RECOMMENDATIONS
The results of the detailed delineation of jurisdictional wetlands and other waters of the US and
the evaluation of surface waters on the site subject or potentially subject to the Neuse River
Basin riparian buffer rule are discussed below.

Wetlands and Jurisdictional Waters:
We have determined that wetlands and jurisdictional waters (i.e., streams, ponds, or lakes) exist
on the site. The wetland sketch map depicts the approximate location of wetlands and
jurisdictional waters identified within the evaluated area. Jurisdictional waters on-site consist of
Feature A (an internittent channel beginning at and below flag SO1), Feature B (an intermittent
channel beginning at the northern property line), Feature C (an intermittent channel below flag
S03), Feature D (a jurisdictional pond), Feature E (an intermittent channel beginning at and
below flag S04) and Feature G (beginning at and below flag SOS). Feature D was a drained pond;
however recent beaver activity has impounded the pond. Therefore the pond remains
jurisdictional and should be surveyed at the waters edge. Features on this site carry a water
quality classification of WS-IV; NSW (See water supply rules below).
Wetlands on-site consist of an emergent wetland/drained pond delineated with flags 100-114A
and 116B, a bottomland forest wetland delineated with flags 119A-129A and 119B-126B, a
bottomland forest wetland delineated with flags 200-208, a beaver impoundment delineated with
flags 300-321A and 322B, a beaver impoundment delineated with flags 322A and 323B-325A
and 330B, a bottomland forest wetland delineated with flags 411 A and B-416A and 414B and a
bottomland forest wetland delineated with flags 420 A and B-428 A and B.
Two marginal areas exists on the property. Feature C contains a marginal stream/linear wetland
beginning at flag 502. Another marginal ephemeral stream/linear wetland exists above feature F
as indicated on the sketch map. S&EC does not believe these areas to be a jurisdictional
wetlands or waters, because these areas exhibit weak evidence of hydrophitic vegetation and
wetland hydrology. However due to the marginal nature of these areas, confirmation of our
determination should be obtained from the USACE. No other wetlands or jurisdictional waters
were found within the project boundaries.
All S&EC flags comprising the wetland and jurisdictional waters delineation should be surveyed
and a Wetland Delineation Map generated for use in USACE approval and permitting. Stream
channels in the field have not been flagged and should be surveyed with points taken at
bends and channel widths noted. The Wetland Delineation Map should include all of the
information listed on the attached `Requirements for Wetland Delineation Maps'. S&EC
delineation flag numbers should be shown on the wetland survey. Please have the property
owner complete the attached agent authorization form if you would like S&EC to act on their
behalf for requesting approval of the wetland delineation. This form will also be used in
preparing a permit application for impacts to wetlands or surface waters when we are provided
with a plan showing the proposed impacts. S&EC cannot conduct correspondence with the
USACE unless we have agent authorization (see attached Agent Authorization). This
authorization form must be filled out in its entirety by the current landowner and sent to
S&EC (a faxed copy is acceptable).

Neuse River Buffers:
The surface waters (i.e., intermittent streams, perennial streams, lakes, ponds or estuaries)
potentially subject to the 50-foot Neuse River Buffers include features A, B, C, D, E, F, G, H, the
impounded beaver pond, and the pond at the headwaters of feature A. No other surface waters are
indicated on either the USGS topographic or Durham County Soil Survey maps. S&EC believes
that Features A (below flag SOl), B (below northern property line), C (below flags S02 and S03),
D (below flags 321A and 322B), E (below flag S04), F (below flag SOS), and the impounded
beaver pond are all subject to the Neuse River Riparian Buffers. However, the NC-DWQ must
confirm our determination regarding the subjectivity of the aforementioned channels in order for
our determination to be valid. Therefore, a site meeting with the NC-DWQ will most likely be
required. S&EC will schedule this meeting unless you advise otherwise.
REGULATIONS
Regulations that apply to jurisdictional wetlands and waters present on the site are discussed
below.
Neuse River Basin Riparian Buffer Rules
The Neuse River Basin riparian buffer rules, which came into effect on 7/22/97, protect up to ~0 feet from the edge
of existing "surface waters" (intermittent streams, perennial streams, lakes, ponds and estuaries) located within the
Neuse River Basin. The 50-foot buffer basically consists of two zones. Zone 1 is measured 30 feet landward from
the top bank of streams and intended to contain an undisturbed-forested area. Zone 2 is measured 20 feet from the
edge of the first zone and is intended to contain a vegetated buffer. A couple of notable points of the rules include
the following: the allowance of grading with re-vegetating within Zone 2 (the outer 20 feet) and the requirement of
mitigation for road crossings greater than 150 feet in width and utility lines running parallel and within the buffers.
Water Supply Waters Rules
Perennial streams within a classified water supply watershed require a 100-foot buffer for new development activities
with greater than 24 percent "built upon" area (i.e., percent covered by impervious or partially impervious cover) and
a 30-foot buffer for activities with less than 24 percent built upon area by the NC-DWQ. (These buffers are in
addition to the 50-foot Neuse River Buffers. The stricter of the two buffers applies to these stream channels.) Other
regulations may also apply.
Durham Development Ordinances
The Durham City-County Zoning Ordinances were revised and adopted on 6/21/99 to include the addition of
"Section 11, Natural Resources Protection Standards". These new standards include Floodplain Protection
Standards, Stream Buffer Protection Standards, Steep Slope Protection Standards, Wetland Protection Standards and
Durham Inventory Site Protection Standards. The Stream Buffer Protection Standards require a 30-foot buffer for
"intermittent streams" and a 50-foot buffer for "perennial streams" indicated on either the USGS quadrangle
topographic maps or USDA Soil Survey of Durham County Map and drain an area twenty-five (25) acres or greater.
The Wetlands Protection Standards require atwenty-five (25) foot buffer for retained wetlands that do not receive a
404 Permit issued by the USACE or 401 Water Quality Certification issued by the NC-DWQ and are greater than 1
acre in size. This buffer can be limited to ten (10) feet if the site employs construction management techniques that
provide at least a comparable level of protection for the wetland areas. Allowable activities within the buffers
include street crossings, utility crossings, passive recreation activities, clearing and re-vegetating for the purposes of

general conditions of Nationwide Permit 39 and that impact less than 1/10 acre per project. Preconstruction
notification and approval by the USACE is required for wetland impacts that exceed 1/10 of an acre and /or
stream channel impacts. Preconstruction notification and approval by the NC-DWQ is required for wetland
impacts that exceed 1/10 of an acre if the property is west of I-95 or 1/3 of an acre if the project is east of I-95.
Preconstruction notification and approval by the NC-DWQ is required for a~ stream channel impacts

impact allowed per project under the nationwide permits is 1/2 acre of wetland and/or 300 linear feet of USACE
important stream channel. Nationwide Permit 39 limits above-grade fills within 100-year floodplains specifically
prohibiting above-grade fill within the floodway. Additionally, Nationwide Permit 39 limits stream channelization
and relocation to streams with an average annual flow of less than 1 cfs.
Per project impacts to vegetated wetlands in excess of 1 acre or impacts to streams that contain "significant aquatic

Therefore, this type of mitigation usually requires that meanders be created within constructed channels. Side-slopes
and beds be vegetated; rip-rap is discouraged.
A complete NC-DWQ 401 Water Quality Certification application for a Nationwide Pernlit has a maximum 60-day
processing period. A complete USACE Nationwide Permit application has a 45-day processing period, while
Individual Permit applications submitted to the USACE have no maximum processing periods. The USACE
requires that all impacts to wetlands or Waters of the US, less than 1/10 acre, be reported to the USACE
within 30 days of the completion of construction.
Nationwide Permits can potentially be utilized if the project is designed to impact up to 1/2 acre of jurisdictional
wetlands or waters of the US including a maximum of 3001inear feet of important stream channel impact under
NWP 39. Cumulative impacts per project over these nationwide thresholds will require an individual permit.
Individual Permits require an analysis to determine that the proposed impact is the least environmentally damaging
practical alternative, typically require compensatory mitigation, notification to adjacent property owners, a public
notice, and may require a public hearing. All impacts greater than 1/10 acre require written justification.
