Construction of the project began in April 2007 with removal of the concrete spillway and drainage of a former mill pond, and continued into January 2008 with final planting completed in February 2008. The Stricker Branch Stream Restoration Project (Project) will provide NCEEP with ' approximately 2,910 Stream Mitigation Units (SMUs). Stricker Branch was designed using Priority I restoration in the old pond bed and Priority ' II restoration for all existing stream channel. All designed channels are Rosgen C4/5. The project is divided into three sections, the Lower Section below Sign Drive, the Middle Section between Sign Drive and the old pond spillway, and the Upper Section which ' includes the relic pond area. Upper Section: The concrete spillway of the mill pond was removed and the remaining water drained from the pond. This was completed in Spring of 2007 and the pond area " " ' was allowed to dry out for approximately 6 months. Priority I restoration was done on this section. There is a rip rap spillway between the storm water BMP pond outside of the easement and the new channel. Work on the pond area was completed in January ' 2008, which completed the project. Middle Section: Priority II stream restoration was done in this section. There are two rip ' rap areas protecting storm water out fall pipes. There is also a sewer line crossing upstream of the culvert and bridge at Sign Drive with two A-vane, step pool structures in this area, which are not part of the conservation easement or restoration. A runoff Swale ' was incorporated as a storm water feature by digging a shallow channel for the runoff to enter the stream, which was then protected with matting, seeding and live stakes. ' Lower Section: Work below Sign Drive was completed first, with completion in August of 2007. This section of the project has had ample time to stabilize and has already held up well through several bank full events as documented in the photo log in Appendix E. ' Priority II restoration was done in this section, with the exception of two sewer line crossings which are not included in the restoration or the conservation easement. A constructed swale diverts storm water from an adjacent parking lot to a stabilized outlet, ' before entering the stream. Based on the Restoration Plan and As-built drawing, the Stricker Branch Site yields ' 2,910 stream mitigation units (2,115 x 1 = 2,115; 795 x 1 = 795; 2,115 + 795 = 2,910). Several easements bisect the project including Duke Power (60 feet), City and County sewer (totaling 60 feet and 60 feet, respectively), and a crossing for the primary land owner (30 feet). While the entire reach from McGill Road to the confluence of Irish Buffalo Creek is approximately 3,200 feet, these easements along with constructability Stricker Branch Stream Restoration Project 1 Monitoring Year 1 of 5 1 issues, especially in the former pond area, causing the length of the final layout to be unpredictable decreased the final SMU's from 3,000 feet to 2,910. One 30 foot section of the city sewer has been decommissioned, but removal of the areal pipe and accompanying easement for inclusion in the project will take negotiations with the city. MAM plans to make every effort to include this section, if possible. Monitoring Plan ' Monitoring of the Project began on August 5t", 2008 with photos and pebble counts, survey work was completed in September and vegetation monitoring took place on October 17th, 2008. Strategies and methodologies laid out in the Monitoring Plan will be ' followed for a minimum of five years of monitoring. The stream will be monitored for stability of dimension, pattern, and profile using standard practices including permanent cross sections, longitudinal profile, and pebble counts. Standardized, permanent (1 Om by I Om) vegetation plots will be monitored for species diversity and survival. Monitoring ' data will be analyzed to determine what remedial actions if any are required and any remedial actions proposed will be detailed in the following monitoring report. ' 2.0 PROJECT BACKGROUND 2.1 LOCATION AND SETTING ' The Stricker Branch Stream Restoration Site (Site) is located in the City of Concord, Cabarrus County, North Carolina on McGill Avenue next to the Gibson Mill redevelopment project off Highway 29. A location map is included in Figure 1. The project site is located in the HUC 03040105 and in the urbanized EEP Targeted Watershed 03040105020040 of the Yadkin River Basin and the 03-07-12 sub-basin. The project watershed is approximately 1.6 sq. mi. flowing into Irish Buffalo Creek, a 303(d)- listed stream. The majority of the Site consisted of highly unstable, incised and straightened stream channel which had been highly altered, degraded, and entrenched ' with almost no woody vegetation. The upper section of the project area was historically an impounded water supply for the former textile mill. This former textile mill has been purchased for redevelopment into a mixed use commercial and residential project, now known as Gibson Mill. The lower section was deeply entrenched/incised and highly unstable with strong visible evidence of actively failing banks. This section was sparsely wooded and contained invasive species such as Chinese Privet ' 2.2 STRUCTURE AND OBJECTIVES ' The objective of the restoration approach was to restore the site to a more naturally functioning stream system designed to address impairment issues typically associated with highly disturbed urban stream systems. • The project will provide ecological, functional lift to the existing system by restoring the stream and riparian habitat to a stable stream type and vegetative community that is appropriate for its particular valley and watershed conditions. Stricker Branch Stream Restoration Project 2 Monitoring Year 1 of 5 • Water quality will be improved by reduced sediment load through stabilization, and nutrient and other pollutant input will be reduced through the addition of ' forested riparian buffers planted with native species. • Forested buffers and reconnection with an active floodplain bench will improve channel hydraulics and system capacity. ' • Improvements to the ecosystem include the addition of in-stream habitat using in- stream structures and bank revetments such as root wads and log vanes. • By providing an appropriate mix of native forest vegetation to create an ' appropriate canopy and under story, the soil structure will improve, leaf litter will be established to support aquatic and terrestrial ecosystems, and shading and ' cooling will provide improved water quality. Together, these improvements will provide functional uplift for the watershed as a whole. t The dimension, pattern, and profile were restored using Rosgen Priority I and II natural channel design techniques, which stabilized the banks and added flood storage and ' habitat diversity. The objective of using these techniques was: • To create a stable bank full dimension and allow greater than bank full storm events to access the floodplain. • To create a pattern that is appropriate and stable for the given stream and valley ' types. • Stream profile was adjusted to decrease the slope by adding length. This improves the channel's ability to handle the sediment load without aggrading or degrading. • The plan also incorporates the use of storm water BMPs located both outside and inside the conservation easement to attenuate and treat runoff from the ' surrounding development and associated impervious surfaces. The stream restoration project and associated conservation easement are surrounded by a larger project involving the redevelopment of the old textile mill by South Paw Investors. The stream buffer design will help control access to the restored channel while allowing for some passive public access and visibility to the restored channel. A water quality detention pond located at the upstream end of the project site was constructed in conjunction with the stream restoration efforts. South Paw Investors will be responsible for the pond and its associated maintenance, which is not within the conservation easement. Table I.

Prelimina Soil Data Series Max Depth in % Clay on Surface K T OM % Chewacla- 70 18 - 35 .28 5 1-4 3.1.2 Vegetative Problem Areas At this time, the only vegetative problem area that could be mentioned is the robust growth of polygonum pennsylvanicum in the former pond area. This affected the plant counts in Vegetation Plots 5 and 6. Living individuals may be present under the polygonum, several were located and pulled free of the dense herbaceous material. Polygonum is a typical first year succession plant and MAM believes that in year 2 other species will begin to dominate as the site finds equilibrium. Some of these missing trees may survive this transition. Treatment of the polygonum or a supplemental planting will only be considered after the Year 2 monitoring plant count. No invasive species problems were observed. The site is stabilized and vegetated with native woody and herbaceous species. 3.1.3 Stem Counts ' Four hardwood planting zones were established as follows: Zone 1 - Stream Bank; Zone 2- Riparian/Bank full Bench; Zone 3 - Transitional; and Zone 4 - Upland. Live stakes were installed along the new constructed channel within Zones 1 and 2; and in some areas of Zone 3. Plantings were spaced approximately 3 feet apart and differed in sizes ranging from .25" to 2" in diameter and 2' to 5' in height. Zones 2 - 4 consist of bare root seedlings in the first half of the lower section and 1 gallon containerized plants, ' which were planted 3' to 12' apart throughout the project. A reduction in the percentage of nuisance vegetation in areas with existing vegetation to less than 15% will indicate establishment of native wetland vegetation. Study plots showing that the composition ' and density of vegetation in the restoration areas compares closely to the reference areas will indicate restoration success for vegetation. Success will be gauged by stem counts of planted species. Stem counts of over 320 woody stems per acre after 3 years and 260 stems per acre after 5 years will be considered successful. Photos taken at established photo points should indicate maturation of riparian vegetation community. Photographs will help to capture the health of the planted vegetation and the severity of any invasive ' or exotic species that establish within the site. Permanent vegetative plots have been established at 6 locations. The success of vegetation plantings will be measured through stems counts. These plots will be used to sample primarily Zones 1 through 3. Each plot ' covers 100 square meters for tree counts. Within each plot, a 1 meter plot will be sampled to measure herbaceous coverage. During the counts, the health of the vegetation ' Stricker Branch Stream Restoration Project 6 Monitoring Year 1 of 5 n 7 H will be noted. In addition to stem counts, the samples will inventory species diversity to allow for comparison between the reference and restoration wetlands and track the percent cover of nuisance species. The vegetation survey will occur during the growing season. On October 27th, 2008, the first year-vegetative monitoring was performed on the established vegetative plots.

' Plot I lost three planted individuals and is host to several small Cottonwood volunteer seedlings. The two largest cottonwood individuals were noted on the grid for future tracking. Herbaceous cover was greater than 75%, with wetland species, primarily Juncus ' effusus dominating. Plot 2 lost no plants, an "extra" river birch was noted and herbaceous cover was greater than 75% and similar in composition to Plot 1. ' Plot 3 lost four individuals and had 100% survival of live stakes. Herbaceous cover is around 75%, with some bare sections on the steeper part of the slope, dominant species include various grasses, including dead annual rye. Herbaceous cover in plots 3 and 4 should improve in year two once the annual rye is succeeded by other perennial grasses. ' Plot 4 sustained damage from sand deposition during bankfull events, most notably the Hurricane event of August 27th, 2008. The sand deposition caused high livestake mortality (greater than 50%). Because the problem in this area is deposition, not erosion, replacement livestakes are not necessary and the plot stem count is still at an acceptable level. Two cottonwood volunteers were also noted in Plot 4. ' As mentioned above in the Section 3.1.2, Plots 5 and 6 are overgrown with a particularly robust variety of polygonum, with stems up to an inch in diameter. Several live individuals were found hidden under this polygonum growth, however not all individuals ' were located and pulled free. This means that some missing individuals could still be alive and may re-emerge when the polygonum dies back and the herbaceous community finds equilibrium. While the stem counts on Plots 5 and 6 are below success criteria ' , MAM believes it is best to wait until after the Year 2 count to determine if any missing individuals can be located. If the polygonum over growth persists into year 2 and stem counts in these plots are still below success criteria, treatment of the polygonum and/or a ' supplemental planting will be considered. Herbaceous cover was 100% with polygonum dominating. Three "extra" river birches were noted in Plot 5 indicating that these may indeed be volunteers not individuals missed during the baseline count. Overall, without the missing and dead individuals, the plant count indicates 58% survival and 367 stems per acre for the site. Counting of four cottonwood volunteers and four river birches that are volunteers and /or may have been missed during the baseline count, brings the stem ' count to 420 overall. In Appendix A, the vegetative survey data tables show the actual counts of each species ' found per plot, stressed and dead plants were noted. The herbaceous cover plant community was monitored in a 1 in by 1 in square at one corner of each plot. Each herbaceous quadrant showed at least 75% cover and all were at or close to 100%. Stricker Branch Stream Restoration Project 8 Monitoring Year 1 of 5 1 1 3.2 CHANNEL STABILITY ASSESSMENT ' 3.2.1 Cross Sections Since as-built documents were submitted, the site has been subject to several bankfull events, including hurricane remnant rainfall on August 27th, 2008. CS 1 and 2 on the ' lower section show no significant change since submittal of the as-built plans. The middle section of the project is the most susceptible to erosion and deposition problems. CS 3 shows some scouring on the left bank, while CS 4 shows deposition on the left ' bank. This is the same sand deposit present in veg plot 4. CS 5 and 6 are located at the end of the upper section (former pond area) where the concrete weir was removed. CS 5 shows some scouring on the right bank. CS 6 shows the most adjustment since the as ' built survey, with slight scouring on both banks. The Cross Section plots are located in Appendix B. ' 3.2.2 Bank Full Events 7 1 r A Crest Stage Gage (CSG) is located near Vegetation Plot 2, below Sign Drive in the lower section of the project. A significant number of bankfull events registered on the CSG and were documented, indicating the flashly nature of the drainage area. The lowest documented bankfull event occurred with rainfall of approximately .65 inches. Rainfall records indicated many more events greater than .65 inches which may also have resulted in bankfull conditions that were not documented. Documentation is shown in the Bank Full Event Photo Log in Appendix E and in the table below. Rain fall data is also presented in table form in Appendix E. Exhibit Table VI. Bankfull Events Site Visit Date Associated Rainfall Event Date Rainfall Amount (Inches) Method Documented 2/1/2008 February 1st and 2nd 2.2 On site/ Photos 3/7/2008 March 4th 1.39 CSG 3/10/2008 March 7th 0.65 CSG 4/18/2008 April 4th and 5th 0.86 CSG 5/16/2008 May 9th and 10th 1.31 CSG 6/24/2008 June 22nd and 23rd 2.67 CSG 8/29/2008 August 25th to 28th 23.02 Photos Stricker Branch Stream Restoration Project Monitoring Year 1 of 5 3.2.3 Longitudinal Profiles Extreme rainfall and bankfull events have produced some changes in the stream profile. Generally, large amounts of sand have and will continue working through the system and moving downstream. Some pool positions have shifted, but depths have remained consistent, in the upper and lower sections. In the middle section, however, sand has ' significantly affected pool depth. The system is designed to continue moving this sand downstream during bankfull events and is expected to do so. 1 1 1 r 1 l Bed material was also sampled at one riffle in each section on Cross Sections 2, 3, and 5. Cross Section 5, in the upper section, is dominated with medium and coarse gravel. Cross Section 3, in the middle section, has a fairly equal distribution of various particle sizes, particularly small cobble, medium gravel and coarse sand. The middle section is the section of the project where sand deposition is most problematic as discussed above and in sections 3.1.4 and 3.2.1. Cross Section 2, in the lower section, is dominated by coarse to fine gravel. 3.2.4 Site Stability Assessment Summary Overall, the stream channel has stabilized well and weathered multiple bankfull events, including several high rainfall events and hurricane remnant rainfall events. Areas that sustained damage due to bankfull conditions were repaired by hand and the contractor was mobilized twice for more significant repairs which are documented in the photo log. The herbaceous vegetative cover has also developed a healthy and diverse community throughout most of the site. The planted trees and shrubs have also done well and are supplemented by an existing buffer community which will provide a seed source for volunteers well suited to the current site conditions.
