Water levels are down below the sheet pile and sandbag dikes, so the construction zone is effectively isolated. The contractor was going to pump a bit more down from within the construction zone into the silt bag and fix up out outlet sandbags. Downstream water clarity looked good. Overall, I was happy with how things looked. Please let me know if I can provide any additional information on this.

Hopefully, the additional pumps will get the construction area dried out quickly.

I visited the site later in the afternoon last Thursday (12/22). By the time I was there, the pump that was installed upstream of the sheet pile was pulling enough that water was not flowing into the construction area even though the water level was above the weir in the sheet pile. The contractor was in the middle of installing an additional pump to pump out the construction area to a silt bag. Turbid water was still leaving the construction area due to the sandbag dike on the outlet being overwhelmed and dislodged. I asked that they reconfigure the sandbags on the outlet as soon as they were able to. I will be going back by today to see how things are looking and follow back with updates.

Due to the recent rains and the amount of stormwater runoff that comes to this site, the impervious dikes have been overwhelmed. I have asked the contractor to look at raising up the weirs in the impervious dikes closer to the elevation of the top of bank. We don’t want to back water up upstream but it appears there is still some storage below bank full height. We have also asked that they consider utilizing a second pump around. Another option the contractor could consider is pumping from within the construction zone out onto the grade and try to let it infiltrate, but we are not sure if the project is too wet for this to be helpful. We will keep you updated on the contractor’s efforts to get this under control. Please let me know if you have any questions or recommendations.
