Town Engineer Jon Eppell says construction crews working on the third and final phase of the Lorne Street flood control project are dealing with the unexpected discovery of black, peat-like material between Crescent Street and the dyke that holds back the Tantramar River.
“We hit some soft spots,” Eppell said today in a telephone interview. “So, we’re putting larger rocks in to stabilize it.”
The softer material, which is being trucked away, pushed in the sides of the new ditch the Beale & Inch crews are digging and caused the service road they’re building to sink slightly, but Eppell says the project is still on track.
He explains that crews will soon begin extending the ditch to the site where a new aboiteau will be installed to discharge storm water through the dyke and into the river at low tide.
“We had to wait for the province to issue the WAWA permit,” he says referring to the Watercourse and Wetland Alteration Permit that is required before work can proceed in environmentally sensitive areas.
Eppell says that the town will need other WAWA permits including one for the digging of a large water retention pond behind the community gardens on Charles Street.
“We probably won’t get that for another month, but it doesn’t matter because we don’t plan to start digging that pond until September to avoid interfering with the nesting of migratory birds,” he explains.
He expects the Crescent Street work to be finished “probably within a week” before crews start installing pipes under Sloan Street.
Meantime, Eppell says all of the work has been completed “except for a couple of minor things” at Sackville’s old Pickard Quarry. A control structure, designed to slow the flow of water down to Lorne Street during heavy storms, is now in place.
He explains that the quarry itself will serve as a water retention pond, smaller than the one that was dug during Phase II of the project south of St. James Street and the one that crews will dig this fall east of Charles.
