There are some areas of concern and areas of immediate need. Table 2A shows a summary of as-built assessment measurement results. Overall the project is performing well. Channel dimension, pattern, and profile appear stable at this time. Vegetation plantings are not succeeding to levels required for mitigation credit. Supplemental plantings will be necessary to meet mitigation requirements. Herbaceous cover is sparse in several areas, thus risking bank stability. Soil amelioration is recommended to improve the compacted soils for plant growth. Invasive vegetation is currently not a problem on this site and no recommendations are being made at this time.

A plan sheet follows which shows locations of areas of concern and plan view of existing conditions overlain as-built conditions. Little Sugar Creek l.) Areas with poor herbaceous cover o These areas (Table 3 below) need supplemental herbaceous plantings in order to establish sufficient vegetation cover to resist erosion. Soil compaction is a problem in many areas and should be addressed when replanting. Table 3A.

Scour along bridge abutment at Station 28+50 o This area should me closely monitored to ensure scour does not continue into the bridge abutment. At this time, the scour is limited to areas around boulders upstream of the bridge abutment. 3.) The constructed channel appears incised o The channel stability should be watched to look for any adverse effects resulting from the incised nature of the channel.

The following was excerpted from 2003 HDR monitoring report section 2.1: The Project Area is located on Little Sugar Creek in the Catawba River Basin (HU No. 03050103) in Mecklenburg County, North Carolina. The stream reach is approximately 4,200 linear feet (LF) in length, bounded by East Boulevard and Princeton Avenue, and lies entirely within Freedom Park and the City of Charlotte (City). Freedom Park is a part of the Mecklenburg County Park and Recreation Department public park system. At this site, Little Sugar Creek has a drainage area of approximately 12 to 14 square miles. The range in drainage area is due to the additional drainage represented largely by Dairy Branch, a tributary that enters Little Sugar Creek within Freedom Park. The headwaters of Little Sugar Creek begin near the interchange of Interstate I-85 and NC 29/49 and flow south- southwest through a highly urbanized portion of the City, including the uptown business district, to Freedom Park. Past records indicate that multiple entities have dredged and/or channelized Little Sugar Creek, including the 4,200 LF of stream within Freedom Park. The dredging of Little Sugar Creek was completed by 1917 to a minimum channel width of approximately 20 feet and depth of 8 feet. Overall, the current alignment has existed since early part of the 1900s. In the mid-1960s and early 1970s, the City initiated an erosion control system along the banks of Little Sugar Creek, as it flows through Freedom Park, using a combination of grouted riprap and concrete bank covering. The bottom of the channel was left in its "natural" conditibn. During July 2002, the County removed the grouted riprap and concrete banking and temporarily stabilized the banks with erosion control matting. Additionally, the large flood control weir structure located approximately 450 feet upstream of Princeton Avenue was removed. The goals of the restoration project were to increase aquatic habitat diversity, improve on-site water quality, stabilize the stream banks using a combination of native vegetation and engineered structures, provide for some floodplain benching and flood storage and to aesthetically enhance the stream setting. ��"` d� ��'`�a,� . . _ _. ._ ...-r.�5: °;i, (41� n. �:a x,Jhi�.�z� -^e : ��:' �i� b.i��i� � �� q t�'"1s41�'1 ����� ��. .A.'��4"�RA�. r ���4. �„a2���� � �;ls $'aCrt�� �� , a �: —+.��, . .;�, ���'+#` �s ., _, � -;�-=: � �� y��� ~'f : � ,� �� �� ' , .�� Y �.y ",��',`; ,,:/+���.1��{l/'` ,i =� ' ,�� � ^ a�'�2_ „ �11p1�` o �'r�ij/''�`����'� ' j� � a,•, � ��,,�,,�?J ' � N J�s!���� �a�Z ��.��, � T ;� ., "�4 t ; , .�et�.�;��;��,;. � +f r !ij �� ' � % ` ��� ` �` ���'� ° '.�-,���`. ���A� �� > �� L'�"�','y'�!� i" -. �i��el�i'^"'��,y���+.�,'`I ; F .�'i'�✓ '�^ll� � ."

No reference area was studied; therefore no comparisons could be made to reference conditions. 2.1.1 Results and Discussion Vegetation within the riparian buffer of Little Sugar Creek is overall considered mixed in success. Many portions of the restoration site were well vegetated with live stakes and naturally regenerating native species of shrubs and trees. Cornus amomum was the predominant healthy live stake species throughout the area. Quercus rubra and Ulmus spp. comprised a large portion of the naturally regenerating trees. Early successional herbaceous species were growing well in some areas . while scantily in others. Because stream banks were steep, in many areas soil conditions were droughty. It was noted that most of the site had compacted soils. Extrapolation from the four plots resulted in an overall average of approximately 160 planted trees per acre for this restoration site. The majority of surviving planted trees was located in a small area at the head of the project. The approximately lower three quarters of the project contained little, if any surviving planted trees. If natural regeneration is included with planted trees, the number is increased to an average of approximately 3240 trees per acre. Both of these estimates are based on a diverse mix of species as well. Natural regeneration obviously plays an important role in the restoration of this site; however, more planted trees are needed to meet mitigation requirements. Invasive plant species on the site included Sorghum halepense and Commelina communis though nowhere abundant. Recommendations include replanting trees to obtain mitigation requirements. The site could benefit from larger containerized trees both for bank stability and aesthetics due to its park setting. Several eroding banks would benefit from native herbaceous species. Soil amelioration is recommended to improve the compacted soils for plant growth. .Further, watering may be necessary for plants to achieve successful establishment due to droughiy conditions. Invasive vegetation is currently not a problem on this site and no recommendations are being made at this time. 2.2 Morphology Restored channel dimension, pattern, profile and substrate were examined during the 2004 as- built assessment. This data will be used as baseline for upcoming monitoring reports. 2.2.1 Results and Discussion Channel dimension varies throughout the project. In riffle sections, the top of bank cross- sectional area ranged from 373 to 658 square feet. Bankfull cross-sectional area ranged from 169 to 372 square feet. Pooi top of bank areas ranged from 740 to 1171 square feet and bankfull cross-sectional areas ranged from 189 to 414 square feet. It should be noted that consistent bankfull indicators are not well-formed on recently constructed channels. Several storm events producing bankfull or greater flows are required before bankfull benches become established. For this reason, the top of bank cross-sectional area measurements will be used for annual comparison purposes. Given that premise, the predicted bankfull cross- sectional area from .the rural North Carolina Piedmont regional curve for a 13.6 square mile drainage area is between 80 and 210 square feet. This corresponds with the field indicators found at Freedom Park. The bankfull cross-sectional predicted by the urban regional curve is between 280 and 400 square feet, which is generally lower than that found for the top of bank measurements at Freedom Park. These results indicate that the channel may be incised and is expected to develop bankfull benches at an elevation below top of bank. The average water surface slope is 0.25%. Riffle slopes ranged from 027% to 1.75%. Run slopes range from 0 to 0.33%. Pool to pool spacing ranged from 171 to 587 feet. Meander wavelength ranged from 403 to 840 feet. Channel radius of curvature ranged from 72 to 232 feet. Channel belt width ranged from 105 to 236 feet. Channel bed materials ranged from a d50 of 0.18 to 1.13mm (fne sarid to very coarse sand) and d84 of 13 to 4.7mm (very coarse sand to fine gravel) in riffles. Pool bed material ranged from a d50 of silt to 0.85mm (coarse sand) and d84 of 0.2 to 23mm (fine sand to very fine gravel). 0 G � � a U d c 0 ,� U � s e � � a H N p� � p� ,� l� M a�. � $t � �^'p h p� ap � �O U ❑ ._. � o � o tD U Q7 F' � N , � v y' Q' �� M��o n �,. p O � .-. � M � o0 aUa°� � � � o0 0.l N� Q O h U �� o��ooco � 7 O p�p V � F 7 N y �n �a)! `� N� Vl � N � � h N n � O 4:. t1 �Uw�'� nj� ,�mm a� r ° � °° � .� ° �. �i � p � F CD U ' � 7 y N H � O � � � O � O w� ry l� M N vl �.1Ut�� � �p � � �y M N t� �k � C � � �i U q o � o � �'a��i �F• � � y Q � ^ O � ? � � p ��c�" V' ..

Areas with poor herbaceous cover o These areas (Table 2 below) need supplemental herbaceous plantings in order to establish sufficient vegetation cover to resist erosion. Soil compaction is a problem in many areas and should be addressed when replanting. Table 2. Locations of Degraded Areas along Little Sugar Creek Stations Problem 25+00 to 28+00 Left bank has oor herbaceous success 31+00 to 32+00 Left bank has oor herbaceous success 34+00 to 35+00 Ri ht bank has oor herbaceous success 37+00 to 44+79 Both banks have oor herbaceous success Throughout (both streams Poor hardwood tree and live stake establishment 2.) Scour along bridge abutment at Station 28+50 o This area should me closely monitored to ensure scour does not continue into the bridge abutment. At this time, the scour is limited to areas around boulders upstream of the bridge abutment. 3.) The constructed channel appears incised o The channel stability should be watched to look for any adverse effects resulting from the incised nature of the channel. �-;5 4 r e -; y! d � .'�-' ' ��� <,�, Tl�?c � �$ .,r . 4t r ��'� �r . f� �•� � .� �, � � z� � - �'' �`I' � �� �' ' f 't 9t r r - ; +�� �. j t ;��'; i ¢ 1 .r��� � k � -t _ r ` ;,�� � ., H"f� �',�, a— i.'_"" _ j'!,"'1'-3 . , 4 .,._��N �i� . n �1 — � .:: tr � l s- �;! �: .�C�'..` � _ ' ' * � � s K e ' � _ .� 'j � .o a j- .an - 1 ": z t n } �L � �«n!5" � � f�,'� ".,.,.a . . . r, . ,.. . ... .. . �. � . �I � I �f.; � x�f's x �' ',r� i i � ��ty5�;�1 +��,� rr 7,'.+y . i� � �� � ,a = � � ' ;er�. y a, ;+ Fd � �� � �A" a' � y f � ,l. a.,r . �� , : v � t �iM1' 3 � tr �i �.tL?�ii -.
