Repairs scheduled for Factory Pond dam

April 19, 2011

SOUTH KINGSTOWN–As the reconstruction for the Factory Pond dam in Green Hill gets underway in April, the town will have finished all the planned dam reconstructions in the town.
Director of Public Services Jon Shock said reconstruction for Factory Pond will begin in April. At the March 28 town council meeting, the town awarded a low bid of $172,000 to East Coast Construction in Portsmouth to undertake the dam repairs. The town will repair the Factory Pond dam to update it to current dam standards and to fix damage incurred from the March 2010 storm.

“The existing earthen dam dates back to the 1800s and doesn’t meet current dam standards,” Schock said.

Shock said in addition to dam reconstruction, the project will also include a fishway passage and FEMA approved scour repairs to the earthen spillway. Schock said the fishway passage will allow fish to migrate upward to spawn.

“During the March storm events of last year, the earthen spillway was scoured,” Schock said. “Improvements to that damn will be to the existing spillway. The March storm events eroded that spillway and dropped the level of the pond by two feet. The repairs will build the spillway back up.”

In addition to the concrete spillway headwall for fish passage, other improvements include new toe drains, new 3 to 1 toe slope for ease of maintenance, a new rip-rap shore protection for wave attenuation and a new articulated concrete block lined emergency spillway.

Shock said rip-rap shore protection would protect against the energy of waves in storm events.
