During the 2019 IRT post‐construction field review of the site, several areas were determined in need of repair. These areas included: 1. Wetland B: outlet headcut (approximate Glade Creek as‐built stream station 22+75) and poor woody stem growth (0.74 acres) 2. Undercut brush mattress (approximate Glade Creek as‐built stream station 22+95 to 23+50) 3. Left bank hillslope erosion (approximate Glade Creek as‐built stream 24+25 to 24+75) Wildlands Engineering, Inc. (Wildlands) submitted a repair plan for the above areas to NC DMS on April 7, 2020 and received plan approval on April 14, 2020. Wildlands Construction mobilized to the site on April 15, 2020 and demobilized on April 17, 2020. Wildlands installed live stakes on April 22, 2020 and Bruton Natural Systems, Inc. planted tublings, containers, and bare root species on April 25, 2020. Changes made to the construction plans are detailed on the attached As‐Built plan set. Planted woody species deviated from the plan based on nursery availability. Installed species by area and quantity are detailed below.
