Land use in watershed in the early part of the last century was primarily agricultural with conversion to urban land uses thereafter., At the time of -plan development the watershed consisted of about 25% residential and urban with about 75% forested. Further development in the,project.headwaters was expected. The channel had been straightened and had gullied and is neighbored on its right. side by a golf course with Burnette road abutting the stream on the left There was significant bank erosion and undercut ,to the point that the road was being undermined. The project involved a Priority II restoration of 1,792 linear feet of impaired channel to 1,937 linear, feet with improved pattern, dimension, and profile for the purpose of improving aquatic habitat-and bed and bank stability. The stream has been stable, but heavy thickets of loblolly pine had developed and were not counted in vegetation plot tallies (approximately 70% of the project easement) leading to inadequate stem counts for several plots. The pines were thinned substantially and those areas were remediated with ,supplemental plantings in October 2010. Transect,data collected by SEPI Engineering & Construction in October 2013 shows a stem density of about 293-stems /acre -in the supplemental planting areas. In general, the buffenhas the needed density within the easement boundary. Goals and Objectives This project has the following goals and objectives: • 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 reduceTurther property loss by stabilizing erodmg,stream banks. • Reconnect the stream to its floodplain and /or establish a new floodplain at a lower elevation • Improve aquatic habitat with the use of natural material stabilization structures such as root wads, cross -vanes, woody debris,, and a riparian buffer. • Provide aesthetic value, wildlife habitat, and bank stability through the creation of a riparian zone. • Stabilize and enhance'the tributary and small drainage that enters the site. Success Criteria Vegetation: The final vegetative success measure will be the survival of 260 5 -year old planted trees per acre at the end of the year 5 monitoring period. As indicated, sections of the site were heavily dominated by loblolly pine and were thinned in 2010. Although not overly dense, a few invasives noted in the figure below were also treated at this time. Transects run in 2013 UT to Tar River SEPI Engineering and Construction EEP Project # 234 2 Closeout Report March 20 14 indicated these areas were averaging about 300 stems per acre (See t'ransect locations in figure below) Other areas that were previously meeting continued to develop. Morphological: The restored reach should remain stable, or if changes occur the movement should be in the direction of increased stability. There should be insignificant changes in,channel cross - section and longitudinal profile from the as-built condition. The pool /riffle spacing should remain constant. Pools should not be filling in or riffles starting'to change to pools. Pebble counts should show a coarsening of the bed material. The morphological measurement did indicate some enlargement in the lower 400 -500 feet as indicated by cross sections 4 and 5 with some, apparent downcut in the profile in this are Some of what was observed in the latter appears to be the deepening of pool features and bedform as compared to the somewhat featureless bed at the project as -built phase. In addition-,the project did not exhibit any bank erosion and in year 5 all of the structures were observed to be °maintaining grade. Hydrological: At�least two bankfull events must be documented. Four overbank events were confirmed between 2007 and 2010. This is a minimum estimate. The project was subject to additional events capable of performing geomorphic work as well.

However, this is not evident on site and the stream bed meets the culvert elevation, at-the very bottom. Some of what,is observed is the development of pools and bedform compared to the somewhat featureless us- built, baseline profile. No structures were installed in this 1_ower section, but all the structures° above it were reported to be holding grade. Approximately 1 % of the project' footage demonstrated bank erosion in the form �of a, gignif cant cut'near the culvert at the top of the project, which was repaired'in 2010 due to infrastructure concerns. Hydrological success criteria have been met. The vegetation success criterion was not °met for, ;sevefal, plots during the standard 5 year monitoring ;period, but remedial,measures have appeared to have addressed these issues based on transect measurements in 2013. EEP recommends that the site be closed as proposed. Contingencies No contingencies are proposed.
