The visible deposits were removed with hand tools. The turbidity curtain on the NE side was secured and a curtain was installed along the SW bank. The exposed slope on the SW side of the creek was temp seeded and mulched and matting and a wattle check placed in the flow path. The SDO was beefed up with Special Sediment Fence. We will monitor as the water level drops to see if there is more material to retrieve. Please let me know if you have any questions or further recommendations.

We were just there last week and the water level was significantly lower, less than a foot deep in most areas. From the report and photos I received, there appears to have been losses on both sides of Little Rockfish Creek. On the northeast side of the creek, where the contractor is currently working on installing pipe piles for the interior bent, the turbidity curtain was overwhelmed by deposits from a gully that had been existing prior to the project but was exacerbated. On the southwest side of the creek, the wattle SDO was overwhelmed by sediment running down the unvegetated slope. My current recommendations are to remove any deposits above the water line with hand tools and anything additional once the water level drops back down. I asked that along with securing the existing turbidity curtain on the northeast side that they also run one along the southwest side of the creek. They were already planning on temporary seed and mulch with a tackifier. Unfortunately I do not think that anything had been put down since our ride- through visit last week when we discussed it. They are going to repair the wattle SDO and any other EC items in disrepair. As discussed last week, once they finish installing the pipe piles for the interior bent on the northwest side of the creek, they can proceed with the bank stabilization that is called for on that side. Please let me know if you have any questions or additional recommendations. I will keep you updated on our restoration efforts.
