I visited the site this morning whereas I observed that a crew had already stabilized the bank and repaired the silt fence (see attached pictures). They were also rebuilding the berms, installing new slope drains and awaiting instruction on what to do about the sediment in the stream. I estimated the site within the stream receiving deposits to be approximately 20 linear feet X 2 to 8 feet wide (see pictures). I instructed the contractors to dewater the impacted site and remove sediment utilizing the established sediment removal guidelines. I also instructed the contractors to try and remove as much sediment from the riprap as possible. Roadside environmental recommended larger and more compacted berms and additional slope drains. Please let me know if this does not meet with your approval or if you have any additional questions or concerns. Also, let me know if you would like a site visit.
