Erosion control

Erosion control devices seemed to properly function after heavy rain fell Monday and Tuesday on the local interstate connector south worksite off Stone Lake Road south of APD 40.

Cleveland Development and Engineering Services Department Director Jonathan Jobe said Tennessee Department of Environment and Conservation officials inspected the job site late Tuesday evening, but he had not spoken to the state agency this morning.

Jobe said the erosion control devices must meet a minimum standard of withstanding a 5-inch rainfall within 24 hours when stormwater flows into an exceptional stream such as Brymer Creek.

The minimum standard on the east end of the new road is 4 inches because that section drains into Stone Lake, which is not classified as an exceptional body of water. In that area, the water topped a silt fence, but Job said the device functioned as designed.

“The water topped the fence at one point and created a spillway,” Jobe said. “That’s what you want to see happen because you want the water to settle.”

The rain measured 4.8 inches between 11 a.m. Monday and 9 a.m. Tuesday at the site located about a third of a mile from Brymer Creek.

Jobe said right now, it seems to be more of a maintenance issue and the erosion control company will clean debris from the check dams and from around silt fences.
