Complaint Description and Writeup

11/29/2019 - " I came across this on Hardin Valley Road on Friday: followed the ditch down to Conner creek at covered bridge and back up to the source which is a new Development on Marietta Church road. The worker on site was pumping the pond through a serenely bag but it wasn’t catching much sediment."

*12/02/2019 - Anthony with Pipe Doctor has been pumping the water down out of the pond in order to keep the pond from over topping. He has called Knox County, Shannon Sayne, on a few occasions when rain is in the forecast to ask if he could pump to gain capacity in the pond. He is pumping through a filter bag with silt fence and 57 stone. Anthony was pumping all day on Friday. The pond did actually overflow this weekend and erode the back side of the pond. Some sediment has entered the creek. The crew was cleaning it up all day today with 5 gallon buckets. I asked that they get a larger pump to gain capacity in the pond to prevent over tipping. We do not want the damn to get cut out and put large amounts of sediment down stream. They have just now cleared the Job and have not stripped top soil yet. The outlet structure is onsite and pipe should be here Wednesday. I have attached pictures for you to review. Let me know if you would like to visit the site.

*12/03/2019 - Chris Sharp, the engineer on record, was on site today and making recommendations to the contractor. He will go out tomorrow and do the official site assessment.

*12/05/2019 - Email from Chris Sharp:

I visited the project site today to perform an erosion control inspection after a report of breaches that resulted from last week’s rainfall. Barring a couple of minor issues, the perimeter controls are functioning properly. After noting the minor deficiencies, I met with the grading contractor. He was already aware of the deficiencies and will have them corrected quickly.

The sediment basin has been installed and the outlet structure was installed yesterday. The remainder of the outlet pipe was installed today. Last week, the pond was dewatered through a silt sack on a gravel bed with silt fence immediately downstream. Earlier this week, I met with the contractor on site and suggested that an additional riprap ring be installed below the silt sack to provide both support for the silt fence and additional sediment impoundment during the remainder of dewatering. The contractor installed the ring immediately and continued dewatering the pond. In my opinion, the grading contractor has done a good job managing erosion controls given the recent rainfall totals. I anticipate that the sediment basin will function more efficiently once the dewatering device has been installed in the basin’s outlet structure.

I attached photographs from my visit today, my inspection report and a map that shows the general locations of the deficiencies. I will perform a follow up inspection next week and send a follow up e-mail.

Please don’t hesitate to contact me if you have questions.

Thanks and have a good evening.
