From: Tim Morris, Project Manager KCI Technologies, Inc. Subject: Oakley’s Bend Stream, Wetland, and Buffer Restoration Site Post Contract IRT Site Review Meeting Tar Pam 01 Person County, North Carolina Contract No. #200205-01 An IRT field review was conducted for the above referenced project on July 27th starting at approximately 9:30 am. Weather was warm, humid, and sunny. The project streams of Oakley’s Bend and T1 were flowing. T2 had intermittent flow throughout the project reach. The comments were discussed during the site walk. There was overall agreement on the proposed levels of intervention and the proposed credit strategy unless specified below. All project reaches and approaches will need to be justified in the mitigation plan; project reaches, including adding any creditable reaches upstream, would be contingent upon an approved jurisdictional determination. T1 - The upstream wooded portion of T1, that is not a project reach was investigated to see that it is a true single thread stream system to contrast to the heavily impacted reach of T1 below the wood line that has been degraded to the point of losing bed and banks and appearing as a swale. - Because this reach is so impacted and devoid of bed and banks, the IRT would like to see a constructed channel (pilot channel) connecting the reach in the woods to the reach identified for restoration. This reach may be a candidate for full restoration credit if during the assessment and design phase it is determined that approach is in the best interest of the project. - If the wetlands that are adjacent to T1 are projected to have an increase in hydrology due to the raising of T1 through Priority 1 restoration, those wetlands may be candidates for Rehabilitation credit if pre-restoration hydrology data is collected. - The thin section of wooded wetland enhancement to the east of the downstream part of T1 will need pre-restoration hydrologic monitoring to document hydrology improvement as a result of the Priority 1 restoration of T1. T2 - There was discussion about the restoration approach for this stream and whether restoring the channel by filling it in place and not creating a new meander pattern may be more appropriate. During the design phase KCI will consider this approach and justify whatever approach is arrived at by looking at the valley/floodplain morphology and topography, the potential functional improvements, and the potential to restore or create riparian wetlands along this reach. - If trees were to be removed, IRT requested incorporating the wood in the channel design. Oakley’s Bend - No changes to the conceptual approach were noted. - The IRT noted that KCI needed to make sure there was sufficient justification for the Wetland Reestablishment adjacent to the E2 section of Oakley’s Bend, because the channel is not proposed to be raised along this reach. General Comments - A map without the buffer hatching in the mitigation plan, so the other project elements were easier to differentiate needs to be in the mitigation plan. - In the mitigation plan the wetlands should be labeled in a similar scheme as the JD to facilitate discussion about specific areas of wetland mitigation. - The IRT requested a figure showing the proposed wetland grading, specifically showing where grading may be less than 6”, between 6” and 1’, and greater than 1’. IRT mentioned that grading for wetland restoration could not exceed 1’ in depth. - There was a question about making sure that there is no planned crossing on T1 upstream of the road. There is no planned crossing of T1 upstream of the road as the landowner has access to his fields from Fitch-Oakley Road. - There was a question about whether the crossing on Oakley’s will be a ford or culvert. The crossing will be a ford as it will be used very infrequently. - It was emphasized that there should be pretreatment of all of the pasture grass anywhere inside of the proposed easement before construction. - The mitigation plan needs to show a map that depicts the location of all of the soil boring locations, not just the locations of the soil descriptions. - The mitigation plan should discuss current vs. anticipated future land uses. Specifically looking at future risks associated with some kinds of land uses like adjacent logging or development. Then there should be discussion on how these risks may influence the design approach, adaptive management, and long-term stewardship. Please reach out if there are any other specific comments or discussions that occurred during the site walk that are relevant to this project and are not captured in this memo.
