REMARxs: Todd,
Attached are copies of the wetland and stream data sheets I prepared for the Northeastern Annexation Area Sewer Main
Extension project in Carrboro that we discussed by phone yesterday. The preliminary plan shows the proposed sewer main
extension alignment along with our field surveyed location of the existing stream alignments, significant trees and other
existing utilities, property lines, etc. Please call me if we need to visit the site, if you have any questions
further in order to provide a letter of concurrence with the wetland and stream determination findings pr ~„
for your help, ~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 strewn of the
highest quality.

This channel evaluation form is intended~to be used onl. as guide to assist landowners and e~nvir nmental professionals in
gathering the data required by the United States Army orps of Engineers to make a preliminary assessment of stream
quality. The total score resulting from the completion of this form is subject to USACE approval and does not imply a
particular mitigation ratio or requirement. Form subject to change -version 06/03. To Comment, please ca11919-876-8441 x 26.

* These characteristics are not assessed in coastal streams.

Notes on Characteristics Identified in Assessment Worksheet
1. Consider channel flow with respect to channel cross-sectional area (expected flow), drainage area, recent precipitation, potential
drought conditions, surrounding land use, possible water withdrawals, presence of impoundments upstream, vegetation growth in
channel bottom (as indicator of intermittent flow), etc.
2. Human-caused alterations may include relocation, channelization, excavation, riprap, gabions, culverts, levees, berms, spoil piles
adjacent to channel, etc.
3. The riparian zone is the area of vegetated land along each side of a stream or river that includes, but is not limited to, the
floodplain. Evaluation should consider width of riparian area with respect to floodplain width, vegetation density, maturity of
canopy and understory, species variety, presence of undesirable invasive species (exotics), breaks (utility corridors, roads, etc.),
presence of drainage tiles, logging activities, other disturbances which negatively affect function of the riparian zone.
4. Evidence of nutrient or chemical discharges includes pipes, ditches, and direct draining from commercial and industrial sites,
agricultural fields, pastures, golf courses, swimming pools, roads, parking lots, etc. Sewage, chlorine, or other foul odors,
discolored water, suds, excessive algal growth may also provide evidence of discharge.
5. Groundwater discharge may be indicated by persistent pools and saturated soils during dry weather conditions, presence of
adjacent wetlands, seeps, and springs feeding channel, reduced soils in channel bottom.
6. Presence of floodplains may be determined by topography and the slope of the land adjacent to the stream, terracing, the extent of
development within the floodplain, FEMA designation if known, etc.
7. Indicators of floodplain access include sediment deposits, wrack lines, drainage patterns in floodplain, local stream gauge data,
testimony of local residents, entrenchment ratio, etc. Note that indicators may relic and not a result of regular flooding.
8. Wetland areas should be evaluated according to their location, size, quality, and adjacency relative to the stream channel, and
may be indicated by beaver activity, impounded or regularly saturated areas near the stream, previous delineations, National
Wetland Inventory maps, etc. (Wetlands must meet criteria outlined in 1987 delineation manual and are subject to USACE approval.)
9. Channel sinuosity should be evaluated with respect to the channel size and drainage area, valley slope, topography, etc.
10. To evaluate sediment deposition within the channel consider water turbidity, depth of sediment deposits forming at point bars and
in pools, evidence of eroding banks or other sediment sources within watershed (construction sites, ineffective erosion controls). In
rare cases, typically downstream of culverts or dams, a sediment deficit may exist and should be considered in scoring.
11. When looking at channel substrate, factor in parent material (presence of larger particles in soil horizons adjacent to the stream), average
size of substrate (bedrock, clay/silt, sand, gravel, cobble, boulder, etc.), and diversity of particle size (riprap is excluded).
12. Indications of channel incision and deepening may include a v-shaped channel bottom, collapsing banks, evidence of recent
development and increased impervious surface area resulting in greater runoff in the watershed.
13. Evaluation should consider presence of major bank failures along the entire reach under evaluation, including uprooted trees on
banks, banks falling into channel, formation of islands in channel as they widen, exposed soil, active zones of erosion, etc.
14. Increased root depth and density result in greater bank stability. Consider the depth and density that roots penetrate the bank
relative to the amount of exposed soil on the bank and the normal water elevation.
15. Assessment of agriculture, livestock, and/or tunber production impacts should address areas of stream bank destabilization,
evidence of livestock in or crossing stream, loss of riparian zone to pasture or agricultural fields, evidence of sediment or high
nutrient levels entering streams, drainage ditches entering streams, loss of riparian zone due to logging, etc.
16. Riffle-pool steps can be identified by a series of alternating pools and riffles. Abundance, frequency, and relative depth of riffles
and pools should be considered with respect to topography (steepness of terrain) and local geology (type of substrate).
Coastal plain streams should be evaluated for the presence of ripple-pool sequences. Ripples are bed forms found in sand bed
streams with little or no gravel that form under low shear stress conditions, whereas, dunes and antidunes form under moderate
and high shear stresses, respectively. Dunes are the most common bed forms found in sand bed streams.
17. Habitat complexity is an overall evaluation of the variety and extent of in-stream and riparian habitat. Types of habitat to look
for include rocks/cobble, sticks and leafpacks, snags and logs in the stream, root mats, undercut banks, overhanging vegetation,
pool and riffle complexes, wetland pockets adjacent to channel, etc.
18. Evaluation should consider the shading effect that riparian vegetation will provide to the stream during the growing season. Full
sun should be considered worst case, while good canopy coverage with some light penetration is best case.
19. Stream embeddedness refers to the extent that sediment that has filled in gaps and openings around the rocks and cobble in the _,_r;
streambed. The overall size of the average particle in the streambed should be considered (smaller rocks will have smaller gaps).
20. Evaluation should be based on evidence of strewn invertebrates gathered from multiple habitats. Scores should reflect
abundance, taxa richness, and sensitivity of stream invertebrate types. (see attached examples of common stream invertebrates on page
4).
21. Evaluation should include evidence of-amphibians in stream channel. Tadpoles and frogs should receive minimum value, while
salamanders, newts, etc. may be assigned higher value.
22. Evaluation offish should consider the frequency and, if possible, the variety of different fish taxa observed.
23. Evaluation of wildlife should include direct observation or evidence (tracks, shells, droppings, burrows or dens, hunting stands, evidence
of fishing, etc.) of any animals using the streambed or riparian zone, to include small and large marmnals, rodents, birds, reptiles,
insects, etc.

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.

Notes on Characteristics Identified in Assessment Worksheet
1. Consider channel flow with respect to channel cross-sectional area (expected flow), drainage area, recent precipitation, potential
drought conditions, surrounding land use, possible water withdrawals, presence of impoundments upstream, vegetation growth in
channel bottom (as indicator of interniittent flow), etc.
2. Human-caused alterations may include relocation, channelization, excavation, riprap, gabions, culverts, levees, berms, spoil piles
adjacent to channel, etc.
3. The riparian zone is the area of vegetated land along each side of a stream or river that includes, but is not limited to, the
floodplain. Evaluation should consider width of riparian area with respect to floodplain width, vegetation density, maturity of
canopy and understory, species variety, presence of undesirable invasive species (exotics), breaks (utility corridors, roads, etc.),
presence of drainage tiles, logging activities, other disturbances which negatively affect function of the riparian zone.
4. Evidence of nutrient or chemical discharges includes pipes, ditches, and direct draining from commercial and industrial sites,
agricultural fields, pastures, golf courses, swimming pools, roads, parking lots, etc. Sewage, chlorine, or other foul odors,
discolored water, suds, excessive algal growth may also provide evidence of discharge.
5. Groundwater discharge may be indicated by persistent pools and saturated soils during dry weather conditions, presence of
adjacent wetlands, seeps, and springs feeding channel, reduced soils in channel bottom.
6. Presence of floodplains may be determined by topography and the slope of the land adjacent to the stream, terracing, the extent of
development withiri the floodplain, FEMA designation if known, etc.
7. Indicators of floodplain access include sediment deposits, wrack lines, drainage patterns in floodplain, local stream gauge data,
testimony of local residents, entrenchment ratio, etc. Note that indicators may relic and not a result of regular flooding.
8. Wetland areas should be evaluated according to their location, size, quality, and adjacency relative to the stream chamiel, and
may be indicated by beaver activity, impounded or regularly saturated areas near the stream, previous delineations, National
Wetland Inventory maps, etc. (Wetlands must meet criteria outlined in 1987 delineation manual and are subject to USACE approval.)
9. Channel sinuosity should be evaluated with respect to the channel size and drainage area, valley slope, topography, etc.
10. To evaluate sediment deposition within the channel consider water turbidity, depth of sediment deposits forming at point bars and
in pools, evidence of eroding banks or other sediment sources within watershed (construction sites, ineffective erosion controls). In
rare cases, typically downstream of culverts or Janis, a sediment deficit may exist and should be considered in scoring.
11. When looking at channel substrate, factor in parent material (presence of larger particles in soil horizons adjacent to the stream), average
size of substrate (bedrock, clay/silt, sand, gravel, cobble, boulder, etc.), and diversity of particle size (riprap is excluded).
12. Indications of channel incision and deepening may include a v-shaped channel bottom, collapsing banks, evidence of recent
development and increased impervious surface area resulting in greater runoff in the watershed.
13. Evaluation should consider presence of major bank failures along the entire reach under evaluation, including uprooted trees on
banks, banks falling into channel, formation of islands in channel as they widen, exposed soil, active zones of erosion, etc.
14. Increased root depth and density result in greater bank stability. Consider the depth and density that roots penetrate the bank
relative to the amount of exposed soil on the bank and the normal water elevation.
15. Assessment of agriculture, livestock, and/or timber production impacts should address areas of stream bank destabilization,
evidence of livestock in or crossing stream, loss of riparian zone to pasture or agricultural fields, evidence of sediment or high
nutrient levels entering streams, drainage ditches entering streams, loss of riparian zone due to logging, etc.
16. Riffle-pool steps can be identified by a series of alternating pools and riffles. Abundance, frequency, and relative depth of riffles
and pools should be considered with respect to topography (steepness of terrain) and local geology (type of substrate).
Coastal plain streams should be evaluated for the presence of ripple-pool sequences. Ripples are bed forms found in sand bed
streams with little or no gravel that form under low shear stress conditions, whereas, dunes and antidunes form under moderate
and high shear stresses, respectively. Dunes are the most common bed forms found in sand bed streams.
17. Habitat complexity is an overall evaluation of the variety and extent of in-stream and riparian habitat. Types of habitat to look
for include rocks/cobble, sticks and leafpacks, snags and logs in the stream, root mats, undercut banks, overhanging vegetation,
pool and riffle complexes, wetland pockets adjacent to channel, etc.
18. Evaluation should consider the shading effect that riparian vegetation will provide to the stream during the growing season. Full
sun should be considered worst case, while good canopy coverage with some light penetration is best case.
19. Stream embeddedness refers to the extent that sediment that has filled in gaps and openings around the rocks and cobble in the ~-;;
streambed. The overall size of the average particle in the streambed should be considered (smaller rocks will have smaller gaps).
20. Evaluation should be based on evidence of stream invertebrates gathered from multiple habitats. Scores should reflect
abundance, taxa richness, and sensitivity of stream invertebrate types. (see attached examples of common stream invertebrates on page
4).
21. Evaluation should include evidence of-amphibians in stream channel. Tadpoles and frogs should receive minimum value, while
salamanders, newts, etc. may be assigned higher value.
22. Evaluation of fish should consider the frequency and, if possible, the variety of different fish taxa observed.
23. Evaluation of wildlife should include direct observation or evidence (tracks, shells, droppings, burrows or dens, hunting stands, evidence
of fishing, etc.) of any animals using the streambed or riparian zone, to include small and large marmnals, rodents, birds, reptiles,
insects, eta - ~ ~ -

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.
