Morgan Creek Floodplain MY -01 Monitoring Report - FINAL 1 March 2012 I. Executive Summary The Morgan Creek Floodplain project is located within the Mason Farm Biological Reserve (MFBR), owned by the University of North Carolina at Chapel Hill (UNC -CH), and was constructed for the North Carolina Ecosystem Enhancement Program (NCEEP). MFBR is located adjacent to the North Carolina Botanical Garden and the A.E. Finley Golf Course. The project is located within the Morgan Creek Local Watershed planning area, 14 -digit HUC 03030002060080. The site has been used for biological research by the UNC -CH. Restoration activities involved the construction of berm openings to increase floodwater access to the restoration site and also establishing native plant community within the open field. Five armored openings were constructed in the berm to reconnect the natural floodwaters of Morgan Creek to floodplain. The project includes the restoration of 14.37 acres of wetlands, the preservation of 5.61 acres of wetlands, and preservation of 3200 linear feet of riparian buffer along the south bank of Morgan Creek. The Catena Group delineated the wetland preservation area in 2005 and the reference wetland in February 2008, none of which were verified by the US Army Corps of Engineers (USACE). Wetland delineation termination forms are included in Appendix G. Project Goals: • Increased overbank flooding to promote wetland habitats. • Attenuation of floodwater sediments and nutrients within the floodplain. • Retention of floodwaters thereby reducing downstream flooding. • Reduced stormwater flow bank shear stress on Morgan Creek thereby improving localized bank and channel stabilization. Project Objectives: • Increase the frequency of floodplain flooding • Restore wetland hydrology to 14.37 acres of impacted wetlands • Preserve a 5.61 -acre wetland • Re- establish native wetland and riparian plant communities • Treat and remove invasive exotic plant species • Preserve 3200 linear feet of riparian buffer on the south bank of Morgan Creek Currently the vegetation is meeting the success criteria with 356 planted stems /acre. Five vegetation plots were monitored using Version 4.2 of the CVS -EEP vegetation monitoring protocol. Level I of this protocol was implemented for MY -01 which excludes natural stems. MY -02 data collection will follow the Level II protocol which includes natural stems. The success criterion for planted woody species is 320 stems /acre after MY -03. A mortality rate of ten percent will be allowed after MY -04 (288 stems /acre), with another ten percent allowed after MY -05 (260 stems /acre). MY -01 vegetation data was collected on August 23, 2011. Data collected for these plots are in Appendix C. Vegetation problem areas include the presence of the invasive exotic kudzu (Pueraria montana) and an area of low planted stem density in the vicinity of vegetation monitoring plot 2. Kudzu was identified as a severe vegetative problem area in three different locations along the berm within the conservation easement.. Additional invasive exotics that were observed during MY -01 include Japanese stiltgrass Ward Consulting Engineers, P.C. Morgan Creek Floodplain MY -01 Monitoring Report - FINAL March 2012 (Microstegium vimineum), porcelain berry (Ampelopsis brevipedunculata), Chinese privet (Ligustrum sinense), Johnson grass (Sorghum halapense), and Japanese honeysuckle (Lonicera japonica). Japanese stiltgrass, Japanese honeysuckle, and porclain berry were observed scattered throughout the, conservation. easement. Although these species are present, the functionality of the project is not expected to be impaired significantly by these species. Wetland Hydrology , Nine groundwater'gauges.were installed according to the specifications of Technical Note HY- IA-3.1 (USACE 1993). The gauges record data every twelve hours and are downloaded on a bi- monthly basis. Seven of these gauges are located within the conservation easement. Five gauges (1, 2, 4, 5, and 6) are in Wetland, Restoration Soil Unit 1, where groundwater is expected to be within 12 inches of the surface for at least 12.5% of the growing season. Two gauges (3 and 9) are in Wetland Soil Unit 2 where the groundwater is expected to be within 12 inches of the surface for at least 5% of the growing season. The growing season is 221 days .(March 27 - Nov 3) (NRCS -USDA 2011). Gauge 8 is located in the Big Woods section of the MFBR at the request of UN_C- CH. Gauge 10 is located upstream in the reference wetland. Gauge 7 was originally established as the reference wetland gauge but was later removed due to impoundment effects from beavers which moved into the area after the gauge was installed. A new reference wetland was chosen and a replacement gauge (Gauge 10) was installed on July 11, 2007. Gauges 1, 2, 5, and 6 within Soil Unit 1 met the wetland hydrological requirements., Gauge 4 of Soil Unit 1 did not meet the anticipated hydrology, having wetland hydrology for only 8% of the growing season. Gauge 4 was installed in an area that appears to be located on an old road bed perpendicular to Morgan Creek which was likely used for agriculture field access. Since the old road bed was likely somewhat compacted-and slightly elevated, it was chosen to test the restoration response compared to the rest of the site. As such, this area is lacking behind the rest of the site. Gauge 3 did not meet the anticipated hydrology for Soil Unit 1 obtaining wetland hydrology for only 2% of the growing season. Gauge 3 is the closest gauge to Morgan Creek and near the edge of the wetland restoration area. A combination of factors are likely influencing the groundwater levels for Gauge 3, primarily being slightly elevated at the toe slope of the berm and the lateral effect of Morgan Creek that may be causing water table drawdown. ' Gauge 9 did meet the anticipated hydrological requirement for Soil Unit-2 obtaining wetland hydrology for 14% of the growing season (Appendix E). Gauge 8 within Big Woods obtained wetland hydrology -for 12%-of the-growing season. The wetland reference gauge obtained wetland hydrology, for 28 %.of the, growing season. Flooding through the berm . openings was observed after rain, events on May 27, 2011, and November 3, 2011. Several onsite data collection methods are being used to correlate the USGS stream gauge height reading and streambank overflow conditions. According to the USGS •surface water level gauge located approximately 1500 ft upstream of the site, similar flood events occurred on . September 7th and 21st of 2011 (See Figure 3). Ward Consulting Engineers, P C. Morgan Creek Floodplain MY -0I Monitoring Report -FINAL 2 March 2012 Precipitation data is collected on site with an RDS rain bucket gauge. On more than one occasion during the monthly gauge downloads, bird scat (i.e. seeds) was observed ' clogging the rain bucket opening resulting in unmeasured rainwater pooling in the bucket. Additionally, ants were establishing colonies directly beneath the rain gauge during the monitoring period. Internal rain bucket wiring was damaged from chewing. ' Due to wildlife interference with the rain bucket data collection, the rainfall data was supplemented with the NC Climate Office (Station name: Chapel Hill - Williams Airport) data (NCCO 2011). A USGS stream gauge located, approximately 1500ft upstream of ' the project site (Station ID #02097517), was used to correlate precipitation data and groundwater gauge data (USGS 2011). ' Summary information/data related to the occurrence of items such as beaver or encroachment, and statistics related to performance of various project and monitoring elements, can be found in the tables and figures in the report appendices. Narrative ' background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly Restoration Plan) documents available on EEP's website. All raw data ' supporting the tables and figures in the appendices is available from EEP upon request. II. Methodology Methodologies follow EEP monitoring report template Version 1.3.1 (01115110) and CVS -EEP Protocol for Recording Vegetation (Lee et a12008). Photos were taken with a digital camera. A Trimble Geo XT handheld unit with sub -meter accuracy was used to collect groundwater gauge locations, vegetation monitoring plot origins, and problem area locations. A. Vegetation Methodologies Five vegetation monitoring plots were monitored according to Level I of the EEP /CVS protocol Version 4.2 was used to collect data for MY -01, which excludes natural stems. CVS data collection was conducted on August 23, 2011. The plots are 10 meters square and marked with 1" diameter PVC pipe at each corner. Data collected for these plots are in Appendix C. Flora of the Carolinas, Virginia, Georgia, and Surrounding Areas (Weakley 2011) was used as the taxonomic standard for vegetation. See figures in Appendix A for monitoring plot locations. B. Wetland Methodologies Nine RDS groundwater monitoring gauges (1 -6; 8 -10) are downloaded bi- monthly to ensure proper function throughout the growing season. Data is provided in an Excel spreadsheet along with incorporation of local rainfall data collected by an on -site rain gauge and supplemented with data from the State Climate Office.

On September 30, 2010, the gauge height reached a maximum height of 7.8 feet in which flow was observed through berm opening #4. An alert has been established ' through USGS to notify monitoring performers of any gauge height of 8.0 feet or greater, where flow will access the floodplain through the berm openings. Monitoring performers are documenting each berm activation event, and correlating gauge height, in order to ' better quantify the volume of flow through the openings during a given rain event for future monitoring purposes.
