information related to site constraints such as topography, building ordinances, accessibility, and
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.
Due to the height and steepness of the existing ramp scone guardrail will be installed as part of
this project Typically, the shoulder is widened when the guardrail is installed. However, to
minimize impacts the guardrail will be installed in the existing shoulder width.
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 March 9, 2000, mitigation will be required when
Page 9 of 12
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
hqp://h2o.enr.state.nc.us/newetlands/strmgide.htrnl.
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

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify: Meuse)?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers. Required
Zone* s ua eafeet) Multiplier Mitigation
1 785.1 3
2 449.6 1.5
Total 1234.6
* Zone 1 extends out 30 feet perpendicular from near banK or cnannei; cone z exienas an
additional 20 feet from the edge of Zone 1.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.
No buffer mitigation is being considered because both Zone 1 and Zone 2 impacts are considered
allowable The guardrail will be installed in Zones 1 and 2 and are within the footprint of the
existing road A 10-foot clearing zone south of the proposed guardrail will temporarily impact
these areas Some fill will be placed in Zone 2 on the east side of the buffer. These areas will be
revegetated and stormwater flow will be diffused prior to entering Zone 2.

Reference: Six Forks Road and I-440 Ramp Widening in Raleigh
City of Raleigh
Dear Mr. Dorney:
We are submitting, herewith, our findings from the environmental analysis
for the referenced project which has been executed by this office. There are no
wetlands within the project study area. One potential jurisdictional stream/Riparian
buffer stream is located near the project study area.
The project is a widening of Six Forks Road and I-440 Ramp in
Raleigh, NC. This widening includes a repaving of the I-440 ramp, addition of a
guardrail within the existing typical section, and a new fill area within the riparian
buffer zone of the adjacent stream channel. Zone 2 is impacted by new construction;
although, only fill is to be placed within the Zone 2 buffer and it is to be revegetated.
Zone i and Zone 2 of an existing typical section are to be impacted by the
installation of a new guardrail. This report is our notification to DWQ of the
proposed project.
Please notify us if you need to field verify this information or if a permit
application is needed. We look forward to working with you and your staff on this
project. Please call if you have any questions or need additional information.
Very truly yours,

Six Forks Road and 1-440 Ramp Widening Project
October 9, 2002
Introduction
The City of Raleigh has contracted Rummel, Klepper, & Kahl, LLP (RK&K) to design the widening of
Six Forks Road and I-440 ramp located in Raleigh, North Carolina. The project consists of widening the
southbound left-turn lane on Six Forks Road to two lanes and widening the I-440 entrance ramp to
accommodate dual merge lanes. The proposed improvements will improve the intersection capacity,
improve safety, and reduce traffic back-up on Six Forks Roads. The widening will begin at the south end
of the existing bridge over I-440 and extend southward to approximately 100 feet north of Browning
Place. It is anticipated that the eastbound I-440 exit ramp will be revised at its intersection with Six Forks
Road. The existing traffic signal at the I-440 Ramp/Six Forks Road/Ramblewood Drive intersection will
be upgraded to accommodate the revised traffic lane arrangements. See Figure 1 for a vicinity map of the
area.
On September 26, 2002 RK&K surveyed the project study area highlighted on Figure 2 for the presence
of significant features. Also, additional searches were performed by GIS within a three-mile radius of the
project study area to determine any additional potential environmental impacts. This report details the
findings of the environmental analysis.
The majority of the project study area consists of pavement from the roads, parking lots, and sidewalks.
Other areas contained office buildings and residential lots planted with Festuca spp. There are a few
wooded areas along the existing right-of-way. RK&K examined the project study area for wetlands based
upon three criteria: hydric soils, hydrophytic vegetation, and hydrology. One stream feature requires
buffer protection along the southeast portion within the project study area.
Methodology and Procedures
RK&K conducted an initial GIS survey of the project study area to examine for the presence of NWI
wetlands. In addition, a GIS survey of the impact area to examine for the presence of unique natural areas,
national pollution discharge elimination systems (NPDES) discharges, historical and archeological sites,
and hazardous waste facilities. RK&K reviewed mapping from the North Carolina Natural Heritage
Program (NHP) for the presence or absence of significant species.
DWQ classifies a stream as a natural body of concentrated flowing water in a natural low area or natural
channel on the land surface. COE classifies a "jurisdictional" stream as any channel, natural or man-
made, that has significant flow and contains aquatic life. The project study area was searched for features
that meet these conditions. One stream was found adjacent to the project study area. It was visually
inspected and GPS'ed along the "top of bank" defined by the DWQ Redbook.
Both the USGS Raleigh West Quadrangle map and Wake County Soil Survey were reviewed for blue-
lined features within or near the project study area. These blue-lined features were field verified. Soils
within the project study area were searched for hydric components.
On September 26, 2002, RK&K field reviewed the study area of Six Forks Road and I-440 ramp for the
presence of wetlands and streams. The area of impacts shown in Figure 3 was walked and visually
1
Six Forks Road and 1-440 Ramp Widening Project
October 9, 2002
surveyed. The assessment of wetland presence on the property was accomplished by using the parameters
outlined in the U.S. Army Corps of Engineers Wetland Delineation Manual (1987). The U.S. Army Corps
of Engineers has been instructed to implement the methodologies outlined in the 1987 Manual to identify
and delineate wetlands as of August 17, 1991, and under the 1992 Energy and Water Development
Appropriation Act. Implementation of the Act remains in effect until revisions to the Federal Manual for
Identifying and Delineating Jurisdictional Wetlands (1989) have been completed. Wetland indicator
plants were identified using the National List of Plant Species that Occur in Wetlands: Southeast (Region
2) (USFWS 1988).
Results
GIS Search Results
Neither NWI-mapped wetlands nor hydric soils occurred within the project study area.
A 3-mile GIS search identified two NPDES point source dischargers within the search radius. The
following dischargers are within the 3-mile radius, but outside of the project study area: Modern Oil
Company (NC 0026875) and Pigeon House Branch (NC 0064025).
A 3-mile GIS search identified nine historical structures: Paschal House, Henry L. Kamphoefner House,
Fadum House, Small House, Matsumoto House and studio, Ritcher House, Crabtree Jones House,
Josephus Daniels House, and Norbum Terrace. Three historical areas were identified within the 3-mile
area: Glenwood Community, Oakwood Community, and the Oakwood North Community. None of these
sites occur within the project study area. There are no known archeological sites located within the
3-mile radius of the project.
According to the GIS search results, seven superfund sites occur within 3 miles of the project study area:
Howard Johnson's/Crabtree Valley, Corning Glass Works, ITT Telecoms Corporation/Alcatel, ESB
Incorporated, Westinghouse Electric Meter and Light, Chloride Automotive Batteries, and Waste
Industries. No superfund sites are located within the project study area.
NHP reports four occurrences of protected species with the 3-mile radius of the project study area:
Squawfoot (Strophitus undulaps) is a state threatened species with a sighting record from 1995, Star-
nosed Mole (Condylura cristata) is a state species of concern with a sighting record from 1991,
Pinewood shiner (Lythrurus matutinus) is a federal species of concern with no date listed, and the
Appalachian Golden-banner (Thermopsis mollis) is a state rare species with a sighting record from 1961.
A NHP search for federally endangered and threatened species as well as federal species of concern
indicated that three endangered, one threatened, and eleven species of concern occur in Wake County.
None of the species were identified within the project study area. Water sources were located adjacent to
the study area; however, none were within the proposed construction limits. Although no aquatic surveys
were performed, no fish, mussel, or amphibian evidence was seen by visual inspections from the stream
bank. No federally listed bird, reptile, mammal, or amphibian was spotted during field investigations.

Six Forks Road and 1-440 Ramp Widening Project
October 9, 2002
Streams
According to the USGS Raleigh West Quadrangle map, one stream feature is shown within the project
study area to the east of Six Forks Road and south of Ramp D. The NRCS Wake County Soil Survey
(1970) does not show any stream features within the project study area. However, the soil survey shows
several intermittent channels adjacent to the project study area. RK&K surveyed the extent of the project
study area and found one stream located east of Six Forks Road between Computer Drive and Ramp D of
the I-440 interchange (See Figure 1) that requires buffer protection. Several grassy ditches and paved
drainage features were identified on the project; but these drainages did not contain natural features, nor
aquatic life, and were not considered as "jurisdictional".
Buffers
The Neuse River Riparian Buffer Rules are applicable to the natural stream located east of Six Forks
Road and south of Ramp D. Ramp D is within the Neuse River buffer zone and includes the following
plans: repaving on the existing alignment, widening along the easternmost portion of the buffer, and
installation of a guardrail. A guardrail will be installed adjacent to the existing roadway (within the
existing typical section) within Zone 1, approximately 12 feet from the edge of the road. Zone 2 will be
impacted along the existing roadway and along a wooded area that may require mitigation (See Figure 4).
• Repaving of Ramp D and the installation of the guardrail will occur within the existing typical
section. Approximately 270 square feet is within Zone 1 and approximately 1,700 square feet is
within Zone 2 of the natural stream. A total of 1,970 square feet of the Neuse River riparian
buffer zone will be impacted of the existing typical section.
The widening of Ramp D will occur outside of the existing roadway. Approximately 25 square
feet of the wooded Zone 2 will be impacted within the slope stakes. Additional impact
calculations are needed to include the 10-foot clear zone used for erosion control measures.
Approximately 205 square feet of the wooded Zone 2 will be impacted within the 10-foot clear
zone. Together, this area totals 230 square feet. Zone 2 will be impacted by less than 40 linear
feet by construction. This area will be filled and revegetated. No concentrated flow will be
directed to the buffer due to the proposed construction.
Wetlands
Vegetation
Six Forks Road is surrounded largely by commercial and residential development. Consequently, very
few potential wetland areas remain within the project area and the majority of the manicured area is
dominated by ornamental shrubs and lawn grasses. Several forested lots remain along the existing right-
of-way. A forested stand surrounding the stream consists of a canopy dominated by loblolly pine (Pinus
taeda), sweetgum (Liquidambar styraciflua), and tulip poplar (Liriodendron tulipifera). The shrub layer
consists of pokeweed (Phytolacca americana), Chinese privet (Ligustrum sinense), and saplings of
mockernut hickory (Carya tomentosa) and American elm (Ulmus americana). The herb layer consists of
Microstegium nepal (Eulalia viminea), Japanese honeysuckle (Lonicera japonica), poison ivy
(Toxicodendron radicans), Virginia creeper (Parthenocissus quinquefolia), common greenbrier (Smilax
rotundifolia), and English ivy (Hedera helix). Few other wooded areas are dominated by loblolly pines.
Six Forks Road and 1-440 Ramp Widening Project
October 9, 2002
Plant communities do not contain hydrophytic vegetation and do not indicate the presence of wetlands on
site.
The absence of hydrophytic species indicate wetland conditions are not present on the site.
2. Soils
Soil mapping on and surrounding the project study area include the following soil series (NRCS, 1970):
Ma Made land (miscellaneous land type in which the areas have been altered by man to the extent
that the profile of the original soils cannot be recognized).
CeB2 Cecil sandy loam, 2 to 6 percent slopes, eroded
CeC2 Cecil sandy loam, 6 to 10 percent slopes, eroded
WwE Wilkes, 10 to 20 percent slopes
All soils within the project area are identified as upland soils and are not included on the Wake County
list of hydric soils list (MRCS ,1970)
Soil series indicate wetland conditions are not present on the site.
Hydrology
RK&K surveyed the project area for indicators of wetland hydrology. Although several man-made
drainage features and one stream exists within the project study area, no wetland hydrological indicators
were found.
The lack of wetland hydrology indicates wetland conditions are not present on the site.
IV. Conclusion
According to GIS surveys and the NHP records, there are no NWI wetlands, NPDES dischargers,
superfund sites, or federally protected species within the project study area. One potentially jurisdictional
stream is located adjacent to the project study area, however, no impacts to the stream area anticipated. A
riparian buffer stream was found, but impacts are minimal and allowable. Therefore, it is believed that no
permit is required. Based upon the U.S. Army Corps of Engineers three-parameter approach, hydrophytic
vegetation, hydric soils, and wetland hydrology must all three exist in order for wetland conditions to
occur. RK&K determined that no wetlands exist within proposed impact area of the Six Forks Road/I-
440 Ramp widening project.
RK&K will be happy to provide any further information you may find necessary regarding this report.
Please call if you have any questions regarding this report.
