When Hannah and I were onsite last Wednesday we determined that cleanup looked really good where the loss was by the creekbank and at the Site 2 wetlands. We found that there was still a 3-4 inches of sediment in a ~ 10’ x 15’ area at the site 4 wetland loss but it was hard to see due to all of the vegetation. They have since retrieved the rest of the sediment at Site 4 and I think they did a good job (see attached photo). They now have ground cover (coir fiber matting or straw mulch) and native seed mix over the entire area of road removal and have replaced all of the contaminated wattles. The stems for reforestation won’t be planted until November. The rest of the project looked really good. Please let me know if you have any questions. Thanks!

The losses weren’t discovered by our crews until this morning. The losses were due in large part the large amount of disturbed area onsite right now related to the removal of the existing road. The first loss site was an area that washed out around the existing slope drain, causing a roadway failure. This sediment eventually made it’s way to the wattle which overtopped on the west/903 side of Burn Coat Creek. The second loss site overtopped a wattle into the Site 2 wetlands. This deposit covered a large area, approximately 30’ x 20’, but was not very deep and more of a thin film. I have cautioned to not over-excavate this site. The third loss site overtopped a wattle into the Site 4 wetlands. This deposit extended approximately 15’ from the project and approximately 10’ wide, 3-4 inches thick. It was difficult to see due to the thick vegetation but I marked the extent of the deposit with some wetland flagging. All of these losses will be recovered using hand tools and all of the contaminated/defunct wattles will be replaced. We have urged them to finish grading and getting some ground cover on what they can to minimize the amount of disturbed area onsite. We are planning to visit this site during our ride-through on Wednesday. I am sorry to have to report these losses. Please let me know if I can provide any additional information.
