Current Land Use
The Nightingale Lane Tributary (unnamed tributary to McMullen Creek - Stream A) has a 0.27-
square mile watershed that is almost entirely built out and comprised of commercial, institutional,
multi-, and single-family residential land use. The upper portion of the watershed is almost
exclusively commercial/institutional comprising the most impervious areas of the entire watershed.
The land use that immediately surrounds the Nightingale Lane Tributary (Stream A) is comprised of
multi- and single-family residential properties with backyards incorporating the majority of the
riparian area and historic floodplain. Three road crossings intersect the tributary at: Osprey Drive,
Kingfisher Drive, and Blue Heron Drive. In addition, a gas/sewer alignment and a large at-grade,
aerial sewer main intersect the stream approximately 100 feet north of the confluence with McMullen
Creek. Table 1. Land Use of Watershed includes the percentage of the land uses and the percentage
of impervious area within each category within the watershed.

Existing Condition of On-Site Streams
MATEC Engineering was contracted by CSWS to provide an Existing Conditions Report, dated
January 19, 2005, for the on-site stream channels and natural communities within the project area.
In general, this report made the following conclusions regarding the on-site jurisdictional stream
features:
• McMullen Creek flows into McAlpine Creek
• Macro invertebrate data suggest poor to fair water quality for McAlpine Creek
• MHAP rated Stream A - Segment 1 (downstream of Blue Heron) as a 74 out of 200 points
• MHAP rated Stream A - Segment 2 (upstream of Blue Heron) as an 84 out of 200 points
• Stream A - Segment 1 has areas of substantial bank erosion
• Stream A - Segment 2 shows signs of significant down-cutting and incision
• A 35-foot SWIM Buffer extends from Kingfisher Drive to McMullen Creek (2,250 If)
In addition to MACTEC, S&ME was contracted by CSWS to perform pre-construction biomonitoring
at three locations along the stream reaches on site. Based on classification for the derived North
Carolina Biotic Index (NCBI) values for Piedmont streams, all of the biomonitoring sites exhibited
impaired benthic macroinvertebrate communities and were considered "poor" for Stream A. In
addition, the NC Index of Biotic Integrity (NCIBI) scores indicate a "poor" classification and the
Water Quality Index (WQI) rated the three sites, fair, average, and average. Based on these results the
Nightingale Lane Tributary is considered to be impaired.
Jurisdictional Determination
In order to verify the existing conditions for the site have not changed since 2005, CWS performed field
work to investigate the on-site jurisdictional waters of the U.S. and wetland areas. On August 8-14,

2008, CWS's Paul Bright, Jamie MacMartin, Thomas Blackwell, and Gregg Antemann, PWS
investigated on-site jurisdictional waters of the U.S. using the U.S. Army Corps of Engineers (USACE) -
Routine On-Site Determination Method. This method is defined in the 1987 Corps of Engineers
Wetlands Delineation Manual.' Jurisdictional waters of the U.S. were classified according to recent
North Carolina Division of Water Quality (NCDWQ)' and USACE guidance. Several NCDWQ Stream
Classification Forms and USACE Stream Quality Assessment Worksheets for Streams A-E are enclosed
(SCP1 - 6).
Jurisdictional Waters of the U.S.
The results of the on-site field investigation indicate that there are five jurisdictional stream channels
(Stream A-E) and one jurisdictional wetland area located within the project area (Figure 1, enclosed).
These streams are unnamed tributaries to McMullen Creek. McMullen Creek flows into McAlpine
Creek and is within the Catawba River basin (HU# 03050103)3 and is classified as "Class C" waters by
the NCDWQ.
Stream A flows southeast through the project area for approximately 3,500 linear feet to its off-site
confluence with McMullen Creek (Figure 1, enclosed). The upper 1,086 linear feet of Stream A
exhibited a strong bed and bank, weak groundwater flow, substrate consisting of silt to cobbles, and
an average ordinary high water width of 3 - 5 feet. Biological sampling of Stream A revealed a weak
presence of amphibians and filamentous algae. Due to the evidence of typical seasonal flow, this
portion of Stream A was classified as a relatively permanent water (RPW) with seasonal flow,
according to USACE/EPA guidance (AJDF, Seasonal RPW Stream A). Seasonal RPW Stream A
scored 36 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 26
out of a possible 71 points on the NCDWQ Stream Classification Form, indicating intermittent status
(SCP1, enclosed). Representative photographs of Seasonal RPW Stream A are enclosed as
Photographs A - B.
The lower 2,4141ineaf -feet of Stfeam A exhibited a sti'oiig bed and bank, moderate sinuosity,
moderate groundwater flow, substrate consisting of sand to small cobbles, and an average ordinary
high water width of 4-8 feet. Biological sampling within Stream A revealed a weak presence of fish,
moderate presence of amphibians and a weak presence of filamentous algae. Due to the evidence of
typical year round flow, this portion of Stream A was classified as a relatively permanent water
(RPW) according to USACE/EPA guidance (AJDF, Perennial RPW Stream A). Perennial RPW
Stream A scored 46 out of a possible 100 points on the USACE Stream Quality Assessment
Worksheet and 34.5 out of a possible 71 points on the NCDWQ Stream Classification Form,
indicating perennial status (SCP2, enclosed). Representative photographs of Perennial RPW Stream
A are enclosed as Photographs D, H, and I.
Stream B flows west through the project area for approximately 95 linear feet to its confluence with
Stream A (Figure 1, enclosed). Stream B exhibited a strong bed and bank, substrate consisting of silt
to cobbles, and an average ordinary high water width of 2.- 3 feet. Due to the evidence of flow for
less than three consecutive months in a typical year, Stream B was classified as non-relatively-
permanent water (Non-RPW) according to USACE/EPA guidance (AJDF, Non-RPW Stream B).
Non-RPW Stream B scored 26 out of a possible 100 points on the USACE Stream Quality Assessment
Worksheet and 19.5 out of a possible 71 points on the NCDWQ Stream Classification Form,

Stream C flows east through the project area for approximately 506 linear feet to its confluence with
Stream A (Figure 1, enclosed). Stream C exhibited a strong bed and bank, substrate consisting of sand
to coarse gravel, and an average ordinary high water width of 2 - 4 feet. Due to the evidence of flow
for less than three consecutive months in a typical year, Stream C was classified as non-relatively-
permanent water (Non-RPW) according to USACE/EPA guidance (AJDF, Non-RPW Stream C).
Non-RPW Stream C scored 26 out of a possible 100 points on the USACE Stream Quality Assessment
Worksheet and 19.5 out of a possible 71 points on the NCDWQ Stream Classification Form,
indicating intermittent status (SCP4, enclosed). A representative photograph of Non-RPW Stream C
is enclosed as Photograph E.
Stream D flows south-southwest through the project area for approximately 470 linear feet before
entering a pipe which discharges into Perennial RPW Stream A (Figure 1, enclosed). Stream D
exhibited a moderate bed and bank, substrate consisting of sand, hydric soils, and an average ordinary
high water width of 2 - 3 feet. Due to the evidence of flow for less than three consecutive months in a
typical year, Stream D was classified as non-relatively-permanent water (Non-RPW) according to
USACE/EPA guidance (AJDF, Non-RPW Stream D). Non-RPW Stream B scored 29 out of a
possible 100 points on the USACE Stream Quality Assessment Worksheet and 19.5 out of a possible
71 points on the NCDWQ Stream Classification Form, indicating intermittent status (SCP5,
enclosed). A representative photograph of Non-RPW Stream D is enclosed as Photograph F.
Stream E flows northeast through the project area for approximately 337 linear feet to its confluence
with Stream A (Figure 1, enclosed). Stream E exhibited a strong bed and bank, substrate consisting of
sand, hydric soils, and an average ordinary high water width of 1 - 4 feet. Due to the evidence of flow
for less than three consecutive months in a typical year, Stream E was classified as non-relatively-
permanent water (Non-RPW) according to USACE/EPA guidance (AJDF, Non-RPW Stream E).
Non-RP :z7 Stream E scored 29 out of a possible 100 paints on the USACE Stream Quality Assessment

is enclosed as Photograph G.
Wetland AA is located in the southeastern portion of the project area adjacent Perennial RPW A and
is approximately 0.14 acre in extent (Figure 1, enclosed). Dominant vegetation within this wetland
includes boxelder (Ater negundo), sycamore (Platanus occidentalis), and river cane
(Arunidaria gigantea). This wetland exhibited low chroma soils (10 YR 4/1) with many distinct
mottles (5YR 4/6), saturation within the upper 12 inches of the soil profile, water marks, water stained
leaves, and drainage patterns within the wetland. This wetland is adjacent to but not directly abutting
to a Perennial RPW, Stream A. A Routine On-Site Determination Form representative of Wetland
AA is enclosed (DP2). Routine On-Site Determination Form representative of on-site non-
jurisdictional upland areas are also enclosed (DP1 and DP3). A representative photograph of Wetland
AA is enclosed as Photograph K.

However, MACTEC had previously contacted the SHPO on June 11, 2001 and received
correspondence back, dated August 15, 2001, stating, "We have conducted a review of the project and
are aware of no properties of architectural, historic, or archaeological significance, which would be
affected by the project." In addition, MACTEC searched the Charlotte-Mecklenburg Historic
Landmarks Commission Designated Local Historic Landmarks list and it revealed no designated
properties within the project area.
Protected Species
A new letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on July 30,
2008 to determine the presence of any federally-listed, candidate endangered, threatened species or
critical habitat located within the project area. As of the date of this submittal, a new response from
NCNHP has not yet been received.
However, MACTEC performed a literature review of the North Carolina Natural Heritage Program's
database which indicated that there exists no record of rare species, significant natural communities,
or priority natural areas at the site or within one mile of the site on June 20, 2001. In addition, a letter
was forwarded to the U.S. Fish and Wildlife Service on June 11, 2001 and a response from the
USFWS was received dated July 31, 2001 stating that "We concur with your determination that the
proposed project will not affect endangered or threatened species and their habitats."
Project Description
The Nightingale Storm Drainage Improvement Project will reduce flooding, dissipate high velocity
storm flows at outfalls, and reduce storm-induced erosion downstream of culverts. Channel
improvements will be performed at prioritized locations on the main channel from the storm water
pipe outfall behind the Lexington Commons Condominiums upstream of Osprey Drive, downstream
to Blue Heron Drive. Stormwater and drainage improvements will include increasing culvert
capacity, improving outfall aprons, and improving and upsizing secondary open channel conveyances.
Downstre,.m of Blu a Heron Drive, the channel improvements will consist of stream enhancement and
restoration. New wetland areas will also be created adjacent to the existing channel.
Restoration/Enhancement techniques along the channel will include grading to improve stream cross
sections and increase pattern, removing debris from the channel, stabilizing the toe of slope, and
stabilizing the banks with vegetation. Structures such as constructed riffles and rack vanes will be
added to improve habitat within the channel. All stream and wetland restoration, enhancement, and
preservation efforts will be implemented within the established conservation easement limits.
Purpose and Need for the Project
Flooding and erosion problems within the project area have been reported by neighborhood residents
and are documented in formal responses to City questionnaires and service requests. Responses to the
City questionnaires identified the problems as street flooding (34 responses); yard flooding (28
responses); channel and yard erosion (26 responses); and structure flooding (14 responses). According
to service requests, frequent road and occasional structure flooding have been reported at both Blue
Heron Drive and Kingfisher Drive. Stream restoration is needed due to the observed degraded stream
conditions.
Design Criteria
The hydrology of the primary system was analyzed using the U.S. Army Corps of Engineers (USACE)
Hydrologic Engineering Center's (HEC) Hydrologic modeling System (HMS) version 2.2.2. The
hydraulics of the open channel primary system was analyzed using the USACE HEC River Analysis
Nightingale SDIP September 10, 2008
Nationwide Permit Application for NWP Nos. 3, 13 27, and 33 CWS Proiect No. 2008-2387
System (RAS) version 3.1.1. The results of the Existing Conditions Analysis (Nightingale Lane
Storm Water Improvements Planning Study & Report, Jordan, Jones, & Goulding, February 2006)
indicate that all of the primary system culverts do not meet current City design standards for the 25-
year design flow; that portions of the open channel do not meet the City design standards for the 2-
year design flow; that the closed pipe portion of the primary system does not meet current City design
standards for the 50- and 100-year design flows; and that the overall performance of the existing
primary drainage system results in the following significant deficiencies:
• Existing culverts at Kingfisher and Osprey Drives are overtopped by the 2-year design storm;
• Existing culverts at Nightingale Drive and the Lexington Commons Condominiums
downstream of Osprey Drive are overtopped by the 10-year design storm;
• Three homes immediately upstream of Blue Heron Drive (7300 and 7301 Park Vista Circle
and 11024 Blue Heron Drive) are flooded for events equal to or less than the 100-year flood
event;
• Other homes near the lower portion of the primary system (McMullen Creek) experience
flooding of their vents, crawl spaces, and air conditioning units;
• Overflow of the closed pipe system occurs throughout its length for the 50-year design event;
• Although no structural flooding occurs as a result of overflow from the closed pipe system,
vent, crawl space, and AC pads are flooded during the 100-year event.
The hydraulics results support observed flooding problems in four general areas:
• Park Vista Circle near the confluence of open channel primary drainage system and
McMullen Creek;
• Blue Heron Drive at open channel primary drainage system;
• Kingfisher Drive at open channel primary drainage system;
• Osprey Drive at open channel primary cirsinagP .system
Improvements to the primary system are necessary to meet current City design standards and to
correct the deficiencies noted above.
Channel Geomorphic Condition and Assessment
A Channel Geomorphic Condition and Assessment was performed on the Nightingale Lane Tributary
downstream of the Blue Heron Drive crossing using Levels II and III of the Rosgen Stream
Classification System (Rosgen, 1996) (Stream Restoration Plan, Nightingale Lane Storm Drainage
Improvement Project, Jordan, Jones, & Goulding, September 2007). In addition, data was collected
from two reference reach sites located in Park Road Park in Charlotte. Both reaches are located on the
same tributary to Little Sugar Creek. The sites had similar physiographic conditions as those found in
the Nightingale tributary watershed.
The results indicate that the Nightingale Lane Tributary is an unstable, urban stream with significant
indicators of incision and downcutting throughout a majority of its length. The severity of the
stream's instability and condition varies throughout its length depending upon the effect of
intersecting roads and culverts, storm inputs, the intersecting gas/sewer alignment, and substrate. Due
to varying channel dimensions and characteristics, the assessment and proposed restoration plan is
comprised of three reaches. The Nightingale Lane Tributary currently exhibits signs of instability
both in degradation (Reaches 1 and 2) and aggradation (Reach 3). In G-type reaches, the channel is
entrenched and exhibits a high bank height ratio and a low width to depth ratio. The E-type reach also

Nationwide Permit Application for NWP Nos. 3, 13 27, and 33 CWS Project No. 2008-2387
show signs of erosion and incision (as indicated by high bank height ratios) and has low width to
depth ratios, thereby functioning like G-type streams. However, this reach does have some connection
with its floodplain, thereby functioning as an E-type stream.

The results of the assessment indicate that Restoration (changes to dimension, pattern, and profile) is
recommended for approximately 1,071 linear feet of stream channel (Station 1+29 to 12+00) and
Enhancement (changes in dimension and/or profile, but not pattern), has been recommended for
approximately 360 linear feet (Station 12+00 to 15+60).
Avoidance and Minimization
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable.
Multiple studies have been completed to document the existing conditions within the project limits.
These studies have been used to focus efforts on currently degraded portions of the stream channels and
to eliminate impacts to areas that do not require any proposed improvements. The geomorphic
assessment was used to determine which segments of Stream A were considered to be candidates for
stream restoration and enhancement. To avoid and minimize permanent impacts to the restore channel,
worksheets were used to compute shear stress in the channel for the 10-year storm event and the 25-year
storm event. These worksheets have been attached as Table S. Since shear stress exceeds 2 lb/fl in
portions of the stream, the engineer is proposing hard stabilization in areas susceptible to erosion.
Proposed Impacts to Jurisdictional Waters
Unavoidable impacts to jurisdictional waters of the U.S. include proposed culvert maintenance, stream
restoration, and channel stabilization activities. Tables 3a. and 3b. list all of the impacts for the project
and which Nationwide Permit is applicable. Table 4 is a summary of all of the impacts, classification of
stream, nature of impact (temporary or permanent) and applicable permit type.
Unavoidable impacts to Wetland AA total approximately 0.14 acre of impacts and are the result of
grading associated with stream restoration and wetland enhancement (Figure 2, enclosed). The stream
restoration plans are proposing to create adjacent wetland areas within the floodplain benches of the
newly relocated stream and this area will likely be enhanced through plantings and grading to include
a total of 0.44 acre of wetland area. The new wetland areas will be located on both sides of the
restored stream channel and will be constructed at or below the elevation of the existing wetland area.
On behalf of CSWS, CWS is submitting a Pre-Construction Notification Application with attachments in
accordance with Nationwide Permit General Condition No. 27 and pursuant to Nationwide Permit

Nightingale SDIP September 10, 2008
Nationwide Permit Application for NWP Nos. 3, 13 27, and 33 CWS Project No. 2008-2387
(NWT) Nos. 3, 13, 27, and 33 and Water Quality Certification Nos. 3687, 3688, and 3689 (enclosed).
The following section provides a narrative of the impacts for the project and the applicable permit.
Infrastructure Improvements (NWP Number 3)
The activities proposed under this permit include, the replacement of sixty feet of 36-inch CMP under
Osprey Drive with a 60-foot long 4x6-foot RCBC, buried 1 foot deep. Rip rap aprons will be installed
immediately upstream and downstream of this structure. Seventy feet of 48-inch RCP under
Kingfisher Drive will be replaced with two 70-foot long 60-inch RCPs. Adjacent rip rap aprons will
also be installed immediately upstream and downstream of this structure. Seventy two feet of 66-inch
CMP located at the Blue Heron Drive crossing will be replaced with a 72-foot long 4x6 foot RCBC
and a 6x4 foot RCBC. In addition to the three culvert replacements, two existing sewer lines will be
protected with rip rap, and outlet protection will be added. All totaled 202 linear feet of temporary
impacts to Perennial streams, 214 linear feet of permanent impacts to Perennial streams, and 62 linear
feet of permanent impacts to Unimportant Intermittent streams is being proposed under Nationwide
Permit No. 3. Please see Tables 3a. and 3b. for a complete listing of impacts taking place under this
permit.
Stream Stabilization (NWP Number 13)
Channel Stabilization is proposed for the Nightingale Lane Tributary from the upstream limit
(immediately upstream of Osprey Drive) downstream to Blue Heron Drive. From Station 39+50 to
Station 20+50, the channel banks will be graded and stabilized with matting and seeding. The
construction of a 496-foot gabion wall within this reach is necessary to protect a parking lot associated
with Lexington Commons Condominiums. It will be buried 6" below the streambed. There will be no
grading of the stream bed in this reach. From Station 21+50 downstream to Station 17+50 (the Blue
Heron Drive culvert), the banks will be graded and stabilized with matting and seeding. Two 90
degree bends within this reach will be protected with rip rap. In addition, the stream bed in this reach
will be graded to create a low flow. channel.
Several in-stream structures (cross vanes, riffles, step pools, etc...) are proposed throughout this
reach. In addition, rip rap aprons will be installed at the confluences of small pipe and drainage
features within the Nightingale Lane Tributary. Temporary impacts proposed include, 1,763 linear
feet of perennial, 232 linear feet of intermittent, and 1,098 linear feet of unimportant intermittent
channel. Perennial impacts include 656 bank feet and 98 linear feet of perennial stream, and 138
linear feet of unimportant intermittent channel. Please see Tables 3a. and 3b. for a complete listing of
impacts taking place under this permit.

Stream Enhancement (NWP Number 27)
Stream Enhancement is proposed for the Nightingale Lane Tributary from Station 12+00 to 15+60
(approximately 360 linear feet). In-stream structures, including step pools, cross vanes and riffles will
be constructed within this reach. The addition of rock and larger substrate will dissipate energy and
reduce potential for degradation. The channel banks will be graded and stabilized with matting and
live stakes. In addition, a vegetated riparian buffer will be established along the top of bank and
protected by a Conservation Easement averaging 20 feet on either side of the stream centerline.
CSWS is requesting to obtain Stream Enhancement credits for the work implemented from Station
0+00 to 1+29 and 12+00 to 15+60.
Stream Restoration (Nationwide Number 27)
Priority 1 Stream Restoration is proposed for the Nightingale Lane Tributary from Station 1+29 to
12+00 (approximately 1,071 linear feet). Within this reach, the stream channel will be relocated to
increase sinuosity; in-stream structures will be installed; stream banks will be graded and stabilized
with matting and live stakes; and a vegetated riparian buffer will be established at the top of bank. In
addition, two wetland areas will be established within the riparian area, totaling 0.44 acre. This entire
area will be protected by a Conservation Easement averaging 57 feet on either side of the channel's
center line. CSWS is requesting to obtain Stream Restoration credits for the work implemented
between Station 1+29 and 12+00.
In addition, forty feet of 48-inch CMP will be removed from the Nightingale Lane Tributary near
Station 34+50, daylighting this portion of stream channel. This portion of Stream A will be regraded
and stabilized. This pipe length has been subtracted from the total permanent impacts for the project.

Compensatory Mitigation
This project will result in a net increase in aquatic resources functions and values within the project
area. Therefore, no compensatory mitigation is proposed- Stream enhancement and restoration
techniques proposed will result in a "functional lift" to Stream A by diversifying in-stream habitat,
stabilizing eroding banks, providing floodplain access, and stabilizing bed erosion.
Please do not hesitate to contact Jarrod J. Karl at 704-432-0966 or jkarl c@r ci.charlotte.nc.us should you

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: Unavoidable impacts to jurisdictional
waters of the U.S. include proposed culvert maintenance stream restoration and channel
Page 3 of 11
stabilization activities. Tables 3a. and 3b. list all of the impacts for the protect and which
Nationwide Permit is applicable. Table 4 is a summary of all of the impacts, classification of
stream, nature of impact (temporary or permanent) and applicable permit type. The following
section provides a narrative of the impacts for the project and the applicable permit.
Unavoidable impacts to Wetland AA total approximately 0.14 acre of impacts and are the
result of grading associated with stream restoration and wetland enhancement (Figure 2,
areas within
the floodplain benches of the newly relocated stream and this area will likely be enhanced
through plantings and grading to include a total of 0.44 acre of wetland area. The new
wetland areas will be located on both sides of the restored stream channel and will be
constructed at or below the elevation of the existing wetland area.
The activities proposed under NWP 3 include, the replacement of sixty feet of 36-inch
CMP under Osprey Drive with a 60-foot long 4x6-foot RCBC, buried 1 foot deep. Rip rap
aprons will be installed immediately upstream and downstream of this structure. Seventy
feet of 48-inch RCP under Kingfisher Drive will be replaced with two 70-foot long 60-inch
RCPs. Adiacent rip rap aprons will also be installed immediately upstream and downstream
of this structure. Seventy two feet of 66-inch CMP located at the Blue Heron Drive crossing
will be replaced with a 72-foot long 4x6 foot RCBC and a 6x4 foot RCBC. All totaled 202
linear feet of temporary impacts to Perennial streams, 214 linear feet of permanent impacts to
Perennial streams, and 62 linear feet of permanent impacts to Unimportant Intermittent
streams is being proposed under Nationwide Permit No. 3. Please see Tables 3a. and 3b. for
a_ complete listing of impacts taking place under this permit.
Channel Stabilization is proposed for the Nightingale Lane Tributary from the upstream
limit immediately upstream of Osprey Drive) downstream to Blue Heron Drive. From
Station 39+50 to Station 20+50, the channel banks will be graded and stabilized with matting
and seeding. The construction of a 496-foot gabion wall within this reach is necessary to
protect a parking lot associated with Lexington Commons Condominiums. It will be buried
6" below the stream bed. There will be no grading of the.-stream. bed_ i.-n-.-this reach. From
Station 21+50 downstream to Station 17+50 (the Blue Heron Drive culvert) the banks will
be graded and stabilized with matting and seeding. Two 90 degree bends within this reach
will be protected with rip rap. In addition, the stream bed in this reach will be graded to
create a low flow channel. Several in-stream structures (cross vanes riffles step pools
etc._..) are proposed throughout this reach. In addition rip rap aprons will be installed at the
confluences of small pipe and drainage features within the Nightingale Lane Tributary.
Temporary impacts proposed included, 1,763 linear feet of perennial stream 232 linear feet
of intermittent, and 1,098 linear feet of unimportant intermittent channel. Please see Tables
3a. and 3b. for a complete listing of impacts taking place under NWP 13.
Stream Enhancement is proposed for the Nightingale Lane Tributary from Station 12+00
to 15+60 (approximately 360 linear feet). In-stream structures including step pools cross
vanes and riffles will be constructed within this reach. The addition of rock and larger
substrate will dissipate energy and reduce potential for degradation. The channel banks will
be graded and stabilized with matting and live stakes In addition a vegetated riparian buffer
will be established along the top of bank and protected by a Conservation Easement
averaging 20 feet on either side of the stream centerline. CSWS is requesting to obtain
Stream Enhancement credits for the work implemented from Station 0+00 to 1+29 and
12+00 to 15+60.
Page 4 of 11
Priority 1 Stream Restoration is proposed for the Nightingale Lane Tributary from Station
1+29 to 12+00 (approximately 1,071 linear feet). Within this reach, the stream channel will
be relocated to increase sinuosity; in-stream structures will be installed; stream banks will be
graded and stabilized with matting and live stakes; and a vegetated riparian buffer will be
established at the top of bank. In addition, two wetland areas will be established within the
riparian area, totaling 0.44 acre. This entire area will be protected by a Conservation
Easement averaging 57 feet on either side of the channel's center line. CSWS is requesting
to obtain Stream Restoration credits for the work implemented between Station 0+00 and
12+00. In addition, forty feet of 48-inch CMP will be removed from the Nightingale Lane
Tributary near Station 34+50, daylighting this portion of stream channel. This portion of
Stream A will be regarded and stabilized.
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
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. Impacts to on-site jurisdictional
waters of the U.S. have been reduced to the maximum extent practicable. Multiple studies have
been completed to document the existing conditions within the project limits. These studies have
been used to focus efforts on currently degraded portions of the stream channels and to eliminate
impacts to areas that do not require any proposed improvements. The geomorphic assessment was
used to determine which semnents of Stream A were considered to be candidates for stream
restoration and enhancement. To avoid and minimize permanent impacts to the restore channel,
worksheets were used to compute shear stress in the channel for the 10-year storm event and the
25-year storm event. These worksheets have been attached as Table 5. Since shear stress exceeds
2 lb/ft2 in portions of the stream, the engineer is proposina hard stabilization in areas susceptible
to

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, available at
http://h2o.enr.state.nc.us/ncwetlands/strm9ide.html.
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.
This project will result in a net increase in aquatic resources functions and values within the
project area. Therefore, no compensatory mitigation is proposed. Stream enhancement and
restoration techniques proposed will result in a "functional lift" to Stream A by diversifying
in-stream habitat, stabilizing eroding banks, providing floodplain access, and stabilizing bed
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://h2o.enr.state.nc.us/wrp/index.htnL If use of the NCEEP is proposed, please

` Boxes checked below shall be supported by completing the appropriate sections in Section III below.
2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 Supporting documentation is presented in Section III.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section HI.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HLA.1 and 2
and Section III.D.1.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section HI.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, omits adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section IH.B.1 for
the tributary; Section 1"11.13:2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite --
and offsite. The determination whether a significant nexus exists is determined in Section III.C below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 189 acres
Drainage area: 101 acres
Average annual rainfall: 42 inches
Average annual snowfall: 5 inches
(ii) Physical Characteristics:
(a) Relationship with TNW:
? Tributary flows directly into TNW.

Project waters are 1 (or les river miles from RPW.
Project waters are 1-2 ,?:rial (straight) miles from TNW.
Project waters are I (or less) aerial (straight) miles from RPW.
Project waters cross or serve as state boundaries. Explain: N/A.
Identify flow route to TNW5: Intermittent Stream A flows to Perennial RPW Stream A, flows to McMullen Creek, flow
to McAlpine Creek (TNW).
a Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.
Tributary stream order, if known: I st.
(b) General Tributary Characteristics (check all that apply):
Tributary is: ® Natural
? Artificial (man-made). Explain:
? Manipulated (man-altered). Explain:
Tributary properties with respect to top of bank (estimate):
Average width: 5 feet
Average depth: 3 feet
Average side slopes: VerVeal (I:i or less).
Primary tributary substrate composition (check all that apply):
® Silts ® Sands ? Concrete
® Cobbles ? Gravel ? Muck
? Bedrock ? Vegetation. Type/% cover:
? Other. Explain:
Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: This is relatively unstable urbanized
stream system. Flow is flashy due to a high level of impervious cover in the waterershed. Stream is incised, with steep, unstable banks.
Presence of run/riffle/pool complexes. Explain: Riffle pool complexes exist but are weak and inconsistent.
Tributary geometry: Relatively straight
Tributary gradient (approximate average slope): 2 %
(c) Flow:
Tributary, provides for: Seasonal tlow
Estimate average number of flow events in review area/year: 20 (fir greaten

(iii) Chemical Characteristics:
Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.).
Explain: watershed has a high level of urbanization. Single and multi-family residential properties are the predominant
land use, with some commercial properties present high in the watershed.
Identify specific pollutants, if known:
6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section I11.1):
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its
adjacent wetlands, then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to
Section III.D:

2. RPWs that flow directly or indirectly into TNWs.
Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that
tributary is perennial:
Tributaries of TNW where tributaries have continuous flow "seasonally" (e.g., typically three months each year) are
jurisdictional. Data supporting this conclusion is provided at Section III.B. Provide rationale indicating that tributary flows
seasonally: The upper 1, 086 linear feet of Stream A was evaluated to have seasonal flow. Stream A exhibited a strong bed
and bank, weak groundwater flow, substrate consisting of silt to cobbles, and an average ordinary high water width of 3 - 5
feet. Biological sampling of Stream A revealed a weak presence of amphibians and filamentous algae. Due to the evidence
of typical seasonal flow, this portion of Stream A was classified as a relatively permanent water (RPW) with seasonal flow,
according to USACE/EPA guidance (AJDF, Seasonal RPW Stream A). Seasonal RPW Stream A scored 36 out of a possible
100 points on the USACE Stream Quality Assessment Worksheet and 26 out of a possible 71 points on the NCDWQ Stream
Classification Form, indicating intermittent status (SCP1, enclosed)..

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of
100 representing a stream of the highest quality.

' Boxes checked below shall be supported by completing the appropriate sections in Section III below.
'For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 Supporting documentation is presented in Section HI.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section III.D.1.; otherwise, see Section IH.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section HI.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for
--the tributary, Section IILB.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section III.C below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:

Identify flow route to TNW':
Tributary stream order, if known:
4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its
adjacent wetlands, then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to
Section III.D: Wetland AA is located on the floodplain of Perennial Stream A. During high-water events there is flow to and from
Wetland AA and Perennial Stream A. Wetland AA also provides habitat for wildlife and stormwater storage. There is therefore a
significant nexus between Wetland AA, Perennial Stream A, and the downstream TNW.
D. DETERMINATIONS OF JURISDICTIONAL FINDINGS. THE SUBJECT WATERS/WETLANDS ARE (CHECK ALL
THAT APPLY):
1. TNWs and Adjacent Wetlands. Check all that apply and provide size estimates in review area:
TNWs: linear feet width (ft), Or, acres.
? Wetlands adjacent to TNWs: acres.
2. RPWs that flow directly or indirectly into TNWs.
Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that
tributary is perennial: Stream A was evaluated to be perennial and exhibited a strong bed and bank, moderate flow, substrate
consisting of silt to cobbles, and an average ordinary high water width of 4-8 feet. Biological sampling within Stream A
revealed in a weak presence of fish, moderate presence of amphibians and a weak presence of filamentous algae. Due to the
evidence of typical year-round flow, Stream A was classified as a relatively permanent water (RPW) according to
USACE/EPA guidance (AJDF, Perennial RPW A). Stream A scored 46 out of a possible 100 points on the USACE Stream
Quality Assessment Worksheet and 34.5 out of a possible 71 points on the NCDWQ Stream Classification Form, indicating
perennial status (SCP2, enclosed).

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of
100 representing a stream of the highest quality.

' Boxes checked below shall be supported by completing the appropriate sections in Section III below.
2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 Supporting documentation is presented in Section III.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section IILD.L; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section IILD.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary r:ith adjacent wetlands, complete Section HI.B.1 for
the tributary, Section HI.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section III.C below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 184 acres
Drainage area: LE acres
Average annual rainfall: 42 inches
Average annual snowfall: 5 inches
(ii) Physical Characteristics:
(a) Relationship with TNW:
? Tributary flows directly into TNW.
® Tributary flows through tributaries before entering TNW.
Project waters are 1-2 1 i . er miles from TNW.
Project waters are I (or less) river miles from RPW.
Project waters are 1-2 «:-ial (straight) miles from TNW.
Project waters are I (or less) aerial (straight) miles from RPW.

McMullen Creek, flow to McAlpine Creek (TNW).
4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.
Tributary stream order, if known: 1 st.
(b) General Tributary Characteristics (check all that apply):
Tributary is: ? Natural
? Artificial (man-made). Explain:
® Manipulated (man-altered). Explain: The majority of this tributary has been piped.
Tributary properties with respect to top of bank (estimate):
Average width: 4 feet
Average depth: 3 feet
Average side slopes: 2:1.
Primary tributary substrate composition (check all that apply):
® Silts ® Sands ? Concrete
? Cobbles ? Gravel ? Muck
? Bedrock ? Vegetation. Type/% cover:
? Other. Explain:
Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: This is an unstable urbanized stream
system. Flow is flashy due to a high level of impervious cover in the waterershed. Stream is incised, .
Presence of run/riffle/pool complexes. Explain: little to no riffle pool complex.
Tributary geometry: Relatively straight
Tributary gradient (approximate average slope): 2 %
(c) Flow:

Explain: watershed has a high level of urbanization. Single and multi-family residential properties are the predominant
land use, with some commercial properties present high in the watershed.
Identify specific pollutants, if known:
6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:Tributary acts a
conduit to transport, water, sediments and nutrients from higher in the watershed to the TNW. The presence of a sandy substrate
helps to remove some polutants. Organic material entering the stream is also transported downstream, providing nutrients for
aquatic life.
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its
adjacent wetlands, then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to
Section III.D:

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of
100 representing a stream of the highest quality.

1 Boxes checked below shall be supported by completing the appropriate sections in Section III below.
' For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 Supporting documentation is presented in Section III.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section III.D.1.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for
the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section III.C below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 1 RI) acres
Drainage area: 26 acres
Average annual raintah: 42 inches
Average annual snowfall: 5 inches
(ii) Physical Characteristics:
(a) Relationship with TNW:
? Tributary flows directly into TNW.
® Tributary flows through tributaries before entering TNW.
Project waters are 1-2 river miles from TNW.
Project waters are f (or less) river miles from RPW.
Project waters are L-2 tci i,il ("straight) miles from TNW.
Project waters are 1 (or less) aerial (straight) miles from RPW.
Project waters cross or serve as state boundaries. Explain: N/A.
Identify flow route to TNW5: Tributary flows to Intermittent Stream A, flows to Perennial RPW Stream A, flows to
McMullen Creek, flow to McAlpine Creek (TNW).
'Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.
Tributary stream order, if known: 1 st.
(b) General Tributary Characteristics (check all that an)lv):
Tributary is: ? Natural
? Artificial (man-made). Explain:
® Manipulated (man-altered). Explain: This tributary has been straightened.
Tributary properties with respect to top of bank (estimate):
Average width: 4 feet
Average depth: 3 feet
Average side slopes: .
Primary tributary substrate composition (check all that apply):
? Silts ® Sands ? Concrete
® Cobbles ? Gravel ? Muck
? Bedrock ? Vegetation. Type/% cover:
? Other. Explain:
Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: This is an unstable urbanized stream
system. Flow is flashy due to a high level of impervious cover in the waterershed. Stream displays high levels of sedimentation .
Presence of run/riffle/nool complexes. Explain: little to no riffle pool complex.
Tributary geometry: Relatively straight
Tributary gradient (approximate average slope): 2 %
(c) Flow:
Tributary provides for. Intermittentbut not seasonal Ilow
Estimate average number of flow events in review area/year: 6-Ill
Describe flow regime: Discreete and confined.
Other information on duration and volume:
Surface flow is: Discrete and confined. Characteristics:
Subsurface flow: ?L n6nown. Explain findings:
? Dye (or other) test performed:
Tributary has (check all that apply):
® Bed and banks
® OHWM6 (check all indicators that apply):
® clear, natural line impressed on the bank ?
? changes in the character of soil
® shelving
® vegetation matted down, bent, or absent ?
® leaf litter disturbed or washed away ?
® sediment deposition ?
® water staining ?
? other (list):
? Discontinuous OHWM.7 Explain:
the presence of litter and debris
destruction of terrestrial vegetation

If factors other than the OHWM were used to determine lateral extent of CWA jurisdiction (check all that apply):
High Tide Line indicated by: ILl Mean High Water Mark indicated by:
? oil or scum line along shore objects ? survey to available datum;
? fine shell or debris deposits (foreshore) ? physical markings;
? physical markings/characteristics ? vegetation lines/changes in vegetation types.
? tidal gauges
? other (list):
(iii) Chemical Characteristics:
Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.).
Explain: watershed has a high level of urbanization. Single and multi-family residential properties are the predominant
land use, with some commercial properties present high in the watershed.
Identify specific pollutants, if known:
6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:Tributary acts a
conduit to transport, water, sediments and nutrients from higher in the watershed to the TNW. The presence of a sandy substrate
helps to remove some polutants. Organic material entering the stream is also transported downstream, providing nutrients for
aquatic life.
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its
adjacent wetlands, then go to Section I1I.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to
Section I11.1):

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of
100 representing a stream of the highest quality.

Explain:
1 Boxes checked below shall be supported by completing the appropriate sections in section III below.
2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 Supporting documentation is presented in Section III.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section III.D.1.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or. both. If the JD covers a tributary witb adjacent wetlands, complete Section III.B.1 for
the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section III.C below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 184 acres
Drainage area: 22 acres
Average annual rainfall: 42 inches
Average annual snowfall: 5 inches
(ii) Physical Characteristics:

Project waters are I (or less) aerial (straight) miles from RPW.
Project waters cross or serve as state boundaries. Explain: N/A.
Identify flow route to TNW5: Tributary flows to Intermittent Stream A, flows to Perennial RPW Stream A, flows to
McMullen Creek, flow to McAlpine Creek (TNW).
4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

(iii) Chemical Characteristics:
Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.).
Explain: The watershed has a high level of urbanization. Single and multi-family residential properties are the
predominant land use, with some commercial properties present high in the watershed.
6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:Tributary acts a
conduit to transport, water, sediments and nutrients from higher in the watershed to the TNW. The presence of a sandy substrate
helps to remove some polutants. Organic material entering the stream is also transported downstream, providing nutrients for
aquatic life.
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its
adjacent wetlands, then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to
Section III.D:

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of
100 representing a stream of the highest quality.

r Boxes checked below shall be supported by completing the appropriate sections in Section III below.
2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 Supporting documentation is presented in Section III.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section HI.D.1.; otherwise, see Section HLB below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbodya is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section.IIL13.1 for
the tributary, Section III.B.2 for any onsite wetlands, and Section IH.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section III.C below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 1 Fn acres
Drainage area: 16 acres
Average annual rainfall: 42 inches
Average annual snowfall: 5 inches
(ii) Physical Characteristics:
(a) Relationship with TNW:
? Tributary flows directly into TNW.
® Tributary flows through tributaries before entering TNW.
Project waters are t-7 river miles from TNW.
Project waters are I (or less) river miles from RPW.
Project waters are 1-2 ,« nai (straight) miles from TNW.
Project waters are 1 (or less) aerial (straight) miles from RPW.
Project waters cross or serve as state boundaries. Explain: N/A.
Identify flow route to TNW5: Tributary flows to Intermittent Stream A, flows to Perennial RPW Stream A, flows to
McMullen Creek, flow to McAlpine Creek (TNW).
Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.
Tributary stream order, if known: 1 st.
(b) General Tributary Characteristics (check all that apply):
Tributary is: ? Natural
? Artificial (man-made). Explain:
® Manipulated (man-altered). Explain: This stream has been straightened.
Tributary properties with respect to top of bank (estimate):
Average width: 3 feet
Average depth: 3 feet
Average side slopes: Vertical (1:1 or less).
Primary tributary substrate composition (check all that apply):
® Silts ® Sands ? Concrete
? Cobbles ? Gravel ? Muck
? Bedrock ? Vegetation. Type/% cover:
? Other. Explain:
Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: This is an unstable urbanized stream
system. Flow is flashy due to a high level of impervious cover in the waterershed. Banks are steep and unstable, extensive erosion is
present.
Presence of run/riffle/pool complexes. Explain: little to no riffle pool complex.
Tributary geometry: Relatively straight
Tributary gradient (approximate average slope): 2 %
(c) Flow:
Tributary provides for: Intermittent but not seasonal flow
Estimate average number of tlow events in review area/year: 6-10
Describe flow regime: Discreete and confined.

Explain: The watershed has a high level of urbanization. Single and multi-family residential properties are the
predominant land use, with some commercial properties present high in the watershed.
6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:Tributary acts a
conduit to transport, water, sediments and nutrients from higher in the watershed to the TNW. The presence of a sandy substrate
helps to remove some polutants. Organic material entering the stream is also transported downstream, providing nutrients for
aquatic life.
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its
adjacent wetlands, then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to
