The company won numerous environmental awards for its plan to turn the quarry into a lake surrounded by “a mosaic of indigenous forest and wetland communities similar to that which would have existed prior to human principally European arrival”. Areas to be restored included farmland, the quarry operations area, and overburden dumps. Supplied Holcim's Westport quarry lake was supposed to be surrounded by native forest and wetland for public use. A Holcim spokeswoman said extensive rehabilitation and stability work on the quarry continued until the company sold the land in 2020. Nearly 1 million trees planted, due to reach maturity in 20 years time, had been planted.
