​As part of the Port Mann Highway 1 project, important environmental and habitat work is taking place on‐and off‐corridor to deliver the project to the highest environmental standards. This work has four main components: Enhancement, Compensation, Construction timing, Protection/Restoration.

There are a variety of environmental compensation sites occurring throughout Langley. This includes work at Brae Slough and Latimer Creek. 

BRAE SLOUGH

Connecting to the Fraser River, Brae Slough is a tidal channel located on McMillan Island near Fort Langley. Over time, the upper portion of Brae Slough filled in, making it difficult for water to flow through the area. Working in collaboration, Kwantlen First Nation and the project team excavated, enhanced and re‐vegetated about 1.3 km of tidal slough habitat to create new year-round habitat for young Chinook and Coho Salmon, native wildlife and amphibians such as Pacific Tree, Red Legged and Green frogs, and North Western and Long Toed Salamanders.

Habitat improvement work included constructing a new channel and planting native vegetation within the existing banks of the slough. 

LATIMER CREEK

The 202 Street Park & Ride Project provides an opportunity to make improvements to local wildlife habitat areas and drainage on the south side of highway 1 near the 200 Street Interchange.

As part of these improvements, local area fish habitat will be relocated and connected directly to Latimer Creek.

A new storm water drainage pond will be constructed and will address drainage issues and improve local flood protection.
