Please add it to the previously submitted permit modification for U-2579B. The 90%plans will be provided when they are ready. Let us know if you have any questions. Dave, We have addressed the water intake concerns as part of the plan.

Public Records Law and may be disclosed to third parties. 1 Smith Creek Stream Relocation Plan: U2579B Site Summary Smith Creek runs parallel to existing west bound Business 40 just east of the interchange with the Winston Salem Northern Beltway in Forsyth County. There are two active fish hatchery ponds on the north side of Smith Creek. Construction of the deceleration lane from Business 40 onto the Winston Salem Northern Beltway resulted in a need to widen the highway toward Smith Creek. In the 2014 permit application, the plans called for armoring Smith Creek with a series of retaining walls and rip rap bank stabilization. Following the initial survey work in 2008, high stormwater flows have accelerated erosion along Smith Creek between Business 40 and the two fish hatchery ponds. The stream bank erosion was further accelerated when the area received several large rain events in 2018. As a result, Smith Creek has migrated closer to existing Business 40, making it impossible to construct the series of retaining walls and rip rap bank stabilization without jeopardizing the fish hatchery ponds. NCDOT has explored a culvert running the distance of Smith Creek. However due to cost, constructability and long-term maintenance concerns, NCDOT has opted to drain the two fish hatchery ponds and relocate Smith Creek and an Unnamed Tributary to Smith Creek into new channels. The relocated channels have been designed using natural channel techniques, maximizing floodplain width for long term stability. A riparian buffer will be planted utilizing native riparian vegetation, including herbaceous plants, shrubs and trees. A monitoring plan for the stream relocation and vegetation success is detailed below (see sections titled "Stream Assessment Success Criteria" and "Vegetation Success"). The area will be held under NCDOT Right of Way and a Control of Access fence will be erected around the site. Water Access for Existing Fish Hatchery The two fish hatchery ponds that will be drained for the stream relocation are part of a larger fish hatchery operation. Currently, the property owner utilizes an existing dam in Smith Creek, just downstream of the existing culvert under Business 40, to keep his ponds at full capacity for aquaculture operations. There is currently an 8-inch pipe that runs from the dam to fill the series of three ponds. Two of the three ponds will be removed to relocate the stream. Since the NCDOT project will remove the inline dam and impact the 8-inch pipe, we needed to provide the property owner a means to access water to fill his remaining pond that is equivalent to his existing operation. NCDOT has reviewed a couple of different methods to maintain water access. One method included an installation of a stream bypass structure which sends water into a pipe that runs the length of the stream relocation. This method was determined infeasible due to maintenance concerns associated with the long flat slope of the proposed pipe. Instead, NCDOT has decided to install an instream vault downstream of the project area where the property owner can place a pump as needed to fill the ponds. NCDOT has investigated the amount of water that is currently being taken from Smith Creek to determine if the property owner's existing methods are in compliance with North Carolina General Statute §143-215.22H(b1). This statute requires 'any person who with draws or transfers 1,000,000 gallons per day' to register and report their withdrawal with the North Carolina Department of Environmental Quality (NCDEQ). If the property owner took two weeks to fill the ponds utilizing the 8" pipe he currently has, then he would remove 230,037 gallons per day. In conversations with the property owner, he fills the pond over a five-week period. The property owner is not currently registered, nor is does NCDOT believe he is required to be registered with the NCDEQ. Since NCDOT's project is going to decrease the amount of water the property owner needs by decreasing the number of ponds, the amount of water being removed from Smith Creek will decrease, and not change his need to register with NCDEQ. If his operations change in the future, it will be the property owner's responsibility to coordinate with NCDEQ. Stream Assessment Success Criteria The stream relocation site shall be monitored for five years or until success criteria are satisfied. Monitoring protocols shall follow the Monitoring Level I outlined in the Stream Mitigation Guidelines, April 2003. NCDOT will evaluate the success of the stream relocation project based on guidance provided by the Stream Mitigation Guidelines disseminated by the United States Army Corps of Engineers-Wilmington District. The survey of channel dimension will consist of permanent cross sections placed at six (6) cross sections (three riffles and three pools). Annual photographs showing both banks and upstream and downstream views will be taken from permanent, mapped photo points. The survey of the longitudinal profile will cover a cumulative total of approximately 2,471 linear feet of channel (2,127' for Smith Creek and 344' for the unnamed tributary. The entire restored length of stream will be investigated for channel stability and in-stream structure functionality. Any evidence of channel instability will be identified, mapped and photographed. Pebble counts shall not be conducted. In the event that success criteria are not being met, remedial measures will be coordinated with resource agencies. The monitoring shall be conducted annually for a minimum of five (5) years after final planting. The monitoring results shall be submitted to resource agencies in a final report within sixty(60)days after completing monitoring. After 5 years, the NCDOT shall contact resource agencies to schedule a site visit to "close out" the mitigation site if the site has met success criteria. If success is not met, NCDOT will make necessary adjustments to the site or pay mitigation fees to cover the impacts. Vegetation Success The success of vegetation and plantings will be measured through stem counts. Permanent quadrants will be used to sample the riparian buffer and restoration wetlands. Survival of the live stakes will be determined by visual observation throughout the five- year monitoring period. Bare root vegetation will be evaluated using three (3) staked survival plots. Plots will be 50ft. by 50ft. If site conditions prevent a 50ft. by 50ft. plot, then the plot will have varying dimensions to encompass an area of 2,500 ft2. All flagged stems will be counted in those plots. Success will be defined as 320 stems per acre after three years and 260 stems per acre after five years. All vegetation monitoring will be conducted during the growing season. Appropriate measures will be taken to control nuisance vegetation during the monitoring period if it affects the success of the planted vegetation. Functional Assessment: Pre and Post construction A NCSAM form was completed for Smith Creek and the UT to Smith Creek. The forms have been attached to this Stream Relocation plan and are labeled Appendix 1. Smith Creek was divided into 3 sections, labeled SA-1, SA-2 and SA-3. SA-1 and 3 received an overall score of low, while SA-2 received a score of medium. The UT-1 to Smith Creek was assessed in its entirety within the project footprint and received an overall score of low. A NCSAM form will be completed after the monitoring period in order to compare the potential functional uplift to pre-project conditions. It was decided with input from NCDOT, USACE, NCDWR, and NCWRC that the form will not be used to determine success of the site, but rather it will be used for comparison of pre and post project functions.
