NC SAM FIELD ASSESSMENT RESULTS
Accompanies User Manual Version 2.1
USACE AID #: SAW-2021-00907 NCDWR #:
INSTRUCTIONS: Attach a sketch of the assessment area and photographs. Attach a copy of the USGS 7.5-minute topographic quadrangle,
and circle the location of the stream reach under evaluation. If multiple stream reaches will be evaluated on the same prope rty, identify and
number all reaches on the attached map, and include a separate form for each reach. See the NC SAM User Manual for detailed descriptions
and explanations of requested information. Record in the “Notes/Sketch” section if supplementary measurements were performed. See the
NC SAM User Manual for examples of additional measurements that may be relevant.
NOTE EVIDENCE OF STRESSORS AFFECTING THE ASSESSMENT AREA (do not need to be within the assessment area).
PROJECT/SITE INFORMATION:
1. Project name (if any): Mayes Meadow 2. Date of evaluation: 6/29/23
3. Applicant/owner name: Bayard Development 4. Assessor name/organization: HAC, ALL
5. County: Mecklenburg 6. Nearest named water body
on USGS 7.5-minute quad: South Prong Rocky River 7. River basin: Rocky
8. Site coordinates (decimal degrees, at lower end of assessment reach): 35.4553, -80.8281
STREAM INFORMATION: (depth and width can be approximations)
9. Site number (show on attached map): Stream B 10. Length of assessment reach evaluated (feet): 100
11. Channel depth from bed (in riffle, if present) to top of bank (feet): 1 Unable to assess channel depth.
12. Channel width at top of bank (feet): 2 13. Is assessment reach a swamp steam? Yes No
14. Feature type: Perennial flow Intermittent flow Tidal Marsh Stream
STREAM CATEGORY INFORMATION:
15. NC SAM Zone: Mountains (M) Piedmont (P) Inner Coastal Plain (I) Outer Coastal Plain (O)
16. Estimated geomorphic
19 valley shape (skip for
Tidal Marsh Stream):
A B
(more sinuous stream, flatter valley slope) (less sinuous stream, steeper valley slope)
17. Watershed size: (skip Size 1 (< 0.1 mi2) Size 2 (0.1 to < 0.5 mi2) Size 3 (0.5 to < 5 mi2) Size 4 (≥ 5 mi2)
for Tidal Marsh Stream)
ADDITIONAL INFORMATION:
18. Were regulatory considerations evaluated? Yes No If Yes, check all that apply to the assessment area.
Section 10 water Classified Trout Waters Water Supply Watershed (I II III IV V)
Essential Fish Habitat Primary Nursery Area High Quality Waters/Outstanding Resource Waters
Publicly owned property NCDWR Riparian buffer rule in effect Nutrient Sensitive Waters
Anadromous fish 303(d) List CAMA Area of Environmental Concern (AEC)
Documented presence of a federal and/or state listed protected species within the assessment area.
List species:
Designated Critical Habitat (list species)
19. Are additional stream information/supplementary measurements included in “Notes/Sketch” section or attached? Yes No
1. Channel Water – assessment reach metric (skip for Size 1 streams and Tidal Marsh Streams)
A Water throughout assessment reach.
B No flow, water in pools only.
C No water in assessment reach.
2. Evidence of Flow Restriction – assessment reach metric
A At least 10% of assessment reach in-stream habitat or riffle-pool sequence is severely affected by a flow restriction or fill to the
point of obstructing flow or a channel choked with aquatic macrophytes or ponded water or impoundment on flood or ebb within
the assessment reach (examples: undersized or perched culverts, causeways that constrict the channel, tidal gates, debris jams,
beaver dams).
B Not A
3. Feature Pattern – assessment reach metric
A A majority of the assessment reach has altered pattern (examples: straightening, modification above or below culvert).
B Not A
4. Feature Longitudinal Profile – assessment reach metric
A Majority of assessment reach has a substantially altered stream profile (examples: channel down-cutting, existing damming, over
widening, active aggradation, dredging, and excavation where appropriate channel profile has not reformed from any of these
disturbances).
B Not A
5. Signs of Active Instability – assessment reach metric
Consider only current instability, not past events from which the stream has currently recovered. Examples of instability include
active bank failure, active channel down-cutting (head-cut), active widening, and artificial hardening (such as concrete, gabion, rip-rap).
A < 10% of channel unstable
B 10 to 25% of channel unstable
C > 25% of channel unstable
6. Streamside Area Interaction – streamside area metric
Consider for the Left Bank (LB) and the Right Bank (RB).
LB RB
A A Little or no evidence of conditions that adversely affect reference interaction
B B Moderate evidence of conditions (examples: berms, levees, down-cutting, aggradation, dredging) that adversely affect
reference interaction (examples: limited streamside area access, disruption of flood flows through streamside area, leaky
or intermittent bulkheads, causeways with floodplain constriction, minor ditching [including mosquito ditching])
C C Extensive evidence of conditions that adversely affect reference interaction (little to no floodplain/intertidal zone access
[examples: causeways with floodplain and channel constriction, bulkheads, retaining walls, fill, stream incision, disruption
of flood flows through streamside area] or too much floodplain/intertidal zone access [examples: impoundments, intensive
mosquito ditching]) or floodplain/intertidal zone unnaturally absent or assessment reach is a man-made feature on an
interstream divide
7. Water Quality Stressors – assessment reach/intertidal zone metric
Check all that apply.
A Discolored water in stream or intertidal zone (milky white, blue, unnatural water discoloration, oil sheen, stream foam)
B Excessive sedimentation (burying of stream features or intertidal zone)
C Noticeable evidence of pollutant discharges entering the assessment reach and causing a water quality problem
D Odor (not including natural sulfide odors)
E Current published or collected data indicating degraded water quality in the assessment reach. Cite source in “Notes/Sketch”
section.
F Livestock with access to stream or intertidal zone
G Excessive algae in stream or intertidal zone
H Degraded marsh vegetation in the intertidal zone (removal, burning, regular mowing, destruction, etc)
I Other: (explain in “Notes/Sketch” section)
J Little to no stressors
8. Recent Weather – watershed metric (skip for Tidal Marsh Streams)
For Size 1 or 2 streams, D1 drought or higher is considered a drought; for Size 3 or 4 streams, D2 drought or higher is considered a drought.
A Drought conditions and no rainfall or rainfall not exceeding 1 inch within the last 48 hours
B Drought conditions and rainfall exceeding 1 inch within the last 48 hours
C No drought conditions
9. Large or Dangerous Stream – assessment reach metric
Yes No Is stream is too large or dangerous to assess? If Yes, skip to Metric 13 (Streamside Area Ground Surface Condition).
10. Natural In-stream Habitat Types – assessment reach metric
10a. Yes No Degraded in-stream habitat over majority of the assessment reach (examples of stressors include excessive
sedimentation, mining, excavation, in-stream hardening [for example, rip-rap], recent dredging, and snagging)
(evaluate for Size 4 Coastal Plain streams only, then skip to Metric 12)
10b. Check all that occur (occurs if > 5% coverage of assessment reach) (skip for Size 4 Coastal Plain streams)
A Multiple aquatic macrophytes and aquatic mosses
(include liverworts, lichens, and algal mats)
B Multiple sticks and/or leaf packs and/or emergent
vegetation
C Multiple snags and logs (including lap trees)
D 5% undercut banks and/or root mats and/or roots
in banks extend to the normal wetted perimeter
E Little or no habitat
F 5% oysters or other natural hard bottoms
G Submerged aquatic vegetation
H Low-tide refugia (pools)
I Sand bottom
J 5% vertical bank along the marsh
K Little or no habitat
*********************************REMAINING QUESTIONS ARE NOT APPLICABLE FOR TIDAL MARSH STREAMS****************************
