A director with the Hoy/Scott Creek Watershed Society is worried Evergreen Line contractors aren't treating Coquitlam as well as Port Moody when it comes to creek protection.
Niall Williams said he found numerous problems during a tour of the construction area along Hoy/Scott Creek last week, including work along the banks without proper sediment containment.
"Maybe they should reopen the environmental assessment because it's different from what they told us." Williams said, "It's worrying."
Since his initial tour, containment fencing has been installed, but Williams said he found a gap as well as a structure of rock and concrete blocks in Hoy Creek that could change the hydrology and was built into the creek when work isn't allowed because it could damage salmon eggs.
"They're normally not allowed in the creek unless it's an emergency," Williams said.
City and ministry officials denied Williams' claims, however, and Port Moody and Coquitlam stream stewards have been invited to a meeting to be apprised of work and environmental monitoring that is taking place during Evergreen Line construction.
"Just so everybody's on the same page as to what those measures area," said project manager Amanda Farrell.
A city of Coquitlam spokesperson said last week's work along Hoy/Scott Creek was to provide access for piling equipment and creek protection should now be in place.
Meanwhile, officials are investigating discharges from Evergreen tunnel construction that flowed into Schoolhouse Creek in Port Moody. Farrell said it's unknown whether iron-laden water had any effect on the creek but monitoring is being stepped up.
Concerns about sediment in Suterbrook Creek during heavy rain storms in February have also been raised.
