The project is fully contained within the property of two landowners. The conservation easement totals 5 1.1 acres. The project area contains the majority of Little Beaver Creek's floodplain. The watershed is approximately 1. 11 square miles (711 Acres). Areas of hydric soils are common along the flat, narrow drainage ways of this watershed. Few intact wetland communities are present, however, as a result of alterations to accommodate agricultural and residential land uses. The main factor in the degradation and impairment for Little Beaver Creek appeared to be cattle farming. Cattle activity destroyed the natural riparian vegetation that once bordered the stream. The lack of vegetation on the highly erodible soils led to increased erosion along the entire reach. Construction began in July 2005. Due to Hurricane Katrina in August 2005 and contractual issues there was a delay in the completion of the construction until 2006, which prevented planting until the dormant 2006/2007. Tropical storm Alberto caused damage in June 2006, which required repair. Collectively, this caused planting to be delayed until February 2007 the official end of construction. The March 2003 Mitigation (Restoration) Plan did not provide specifics regarding the proposed stream and wetland assets for this project. The January 2007 Mitigation Report (baseline document) was the first documentation of the assets at 3,712 linear feet of restored stream, 1,513 linear feet of preserved stream, 4.9 acres of restored wetlands and 0.9 acres of enhanced wetlands. Succeeding monitoring reports showed the same assets for stream restoration and preservation but the wetland assets were reduced to 2.4 acres of wetland restoration. In preparation for closeout DMS staff adjusted the type and amount of wetland assets proposed for closeout of the site, based on the work done at the site and subsequent review of the site and monitoring data, to what are depicted in the Asset Table. Standard monitoring activities were suspended between 2010 and 2013 as DMS assessed various repair/remediation strategies. Between January 14 and May 6, 2013, spot repairs were made to the stream channel, unwanted/invasive plants were treated, pine and sweet gum saplings were thinned and supplemental planting was conducted. The channel repair included direct work on approximately 400 feet of channel within reaches 2 and 3a and was primarily focused on the removal of poorly sized, failing structures from the original construction. This involved spot reshaping and grading to reduce bank heights and slopes and to substitute constructed riffles and lifts for the poorly constructed structures. Thinning of pine and sweet gum saplings was done in the outer 40 feet of the 50 -foot stream buffer in an attempt to improve species diversity. No thinning was done within the 10 feet immediately adjacent to the stream to avoid incurring any potential destabilization of the streambanks. All areas where repair and thinning activities occurred were replanted with native hardwoods and supplemental planting was done throughout the easement focusing on the first 50 feet from top of bank and areas with sparse woody stem growth. A total of 7,395 woody stems were installed as part of this effort. For more information about the repairs, please see the remediation map in this report and 2013 Supplemental Monitoring Report (Appendix F) in the MY 5 Report. Beaver management was conducted by APHIS in 2011, 2012, 2014, 2015 and 2016. Goals and Objectives: • Restore 4,609 linear feet of Little Beaver Creek (as measured along the centerline) and 951 linear feet of unnamed tributaries to Little Beaver Creek. • Provide a stable stream channel that neither aggrades nor degrades while maintaining its dimension, pattern, and profile with the capacity to transport its watershed's water and sediment load. • Improve water quality and reduce erosion by stabilizing the stream banks. • Reconnect the stream to its floodplain. • Improve aquatic habitat with the use of natural material stabilization structures such as root wads, rock vanes, woody debris, and a riparian buffer. • Provide aesthetic value, wildlife habitat, and bank stability through the creation or enhancement of a nparian zone. • Restore characteristic hydrologic regime to disturbed wetlands. • Restore characteristic plant communities and animal habitat to disturbed wetlands. • Increase the capacity of disturbed wetlands to perform characteristic functions such as flood storage, biogeochemical cycling, runoff attenuation, and maintenance of plant and animal habitat and species diversity. Success Criterion Success Criteria Measured Parameter Criteria Met 10 cross sections: Yes - The majority of Little Beaver Stream Channel Stability: 5 riffle & 5 pool Creek, Reaches 1, 2 and • Cross-sections 3 are in stable condition with some • Longitudinal profile longitudinal profiles by reach isolated bank scour areas, three Measurements should show little structures with some piping. The change from the as -built cross- portion of Little Beaver Creek below sections and profile; pool/riffle station 38+00 to the culvert at the end of the restored reach is stable and spacing should remain constant; well vegetated. Two tributaries pools should not be filling in or located on the project site tie into the riffles starting to change to pools north bank of Little Beaver Creek. Tributary 1 is exhibiting some very minor bank scour but remains in stable condition. Tributary 2 is very stable with vegetation that has established throughout the channel bed and banks.

Conclusion The project includes an expansive easement with buffer widths ranging from 80 to 500 feet along the vast majority of its length. The majority of the cross sections exhibited little change or changes that indicate channel stability. Areas identified for wetland preservation or creation exhibited characteristics and measured hydrology that support their status as wetlands and their mitigation level. The project also includes wetland features that are non -credited. Four overbank events were documented and it is very likely this is an absolute minimum. The project has met all of its success criteria and is recommended for regulatory closure with the assets specified in table 1. Contingencies None Pre -Construction Photos: Appendix A: Watershed Planning Summary - Little Beaver Creek Watershed Characteristic Overview Little Beaver Creek is a stream and wetland restoration and preservation project located in Wake County, southwest of the Town of Apex in the Cape Fear River Basin. It is located within HUC 03030002060160, the Beaver Creek watershed, which was identified as a Targeted Local Watershed (TLW) in the 2009 Cape Fear River Basin Restoration Priorities Plan (RBRP). This project is located within the Lower New Hope watershed. Currently, DMS has no other projects in this TLW. The Beaver Creek watershed is 16% agricultural, 66% forested and 3% impervious. In addition, the majority of this watershed is designated as a Water Supply Watershed by NCDWR. According to the 2009 RBRP, improving water quality flowing to Jordan Lake is the highest priority in the Cape Fear 03030002 Catalog Unit. Little Beaver Creek drains directly into Jordan Lake which is designated as a Nutrient Sensitive Water Supply Watershed by the NCDWR and the Little Beaver Creek project is approximately 3.5 miles upstream of the lake. Much of the land in this watershed has been protected by the Army Corps of Engineers as a consequence of the creation of Jordan Lake. Apex has successfully protected over 120 acres of floodplain with help from CWMTF. Continued preservation efforts and stormwater treatment are recommended to limit NPS pollution from this HU to Jordan Lake. Links to Watershed Goals and Objectives Priorities of the Little Beaver Creek stream and wetland project include contributing to improved water quality and reduced streambank erosion onsite as well as re-establishing floodplain connectivity and wetland hydrology. Historically the site was impacted largely by cattle activity and the implementation of this project resulted in 3,721 if of stream restoration and 1,631 if of stream preservation as well as 2.62 acres of wetland restoration/preservation. The establishment of riparian buffer and wetland vegetation will increase filtration of inputs prior to entering the stream and also provide habitat improvements and the additional stabilization of the stream banks reduce direct sediment inputs and improve floodplain connectivity. These project improvements will contribute towards improving the downstream water quality condition of Jordan Lake. Watershed Summary In addition to the Little Beaver Creek project, there is one agricultural BMP, a livestock exclusion site, located within this watershed based upon DSWC data as of 2014. 2016 DMS Project Closeout: Little Beaver Creek t� f J Lis -64- / j 1 -•� 1/ � -.,�' ,r Apex ` PE FEA 4 t.� + Little Beaver Creek Legend yy 201E Closeout Project 0 DMS Projects % Middle Cape Fear _ Agricultural BMPs /Kenneth and Parker Creeks LWP Cataloging Unit - Target Local Watersheds r /7 Local Watershed Plans !..
