CBM Aggregates’ Coburn Pit receives the 2022 Progressive Rehabilitation Award
from the Ontario Stone, Sand, and Gravel Association (OSSGA). The award recognizes the ongoing
efforts of individual operators to progressively rehabilitate their sites per their site plans.
A total of 2.5 hectares of Coburn Pit’s northwest portion of land was targeted during its multi-year
rehabilitation. The objective was to restore the site to a natural area and wetland that blends into the
adjacent Mill Creek corridor. The site was seeded with a mix of fescue, bluegrass, trefoil and perennial
ryegrass, as well as a seeding supplement of native grass and wildflowers and a direct seeding of oak
“CBM is very pleased to accept the five Progressive Rehabilitation awards from OSSGA. We continue to
be focused on raising the bar each year in our rehabilitation efforts and are thrilled to be recognized by
the industry for our achievements,” says David Hanratty, Director of Land, Resource & Environment,
Additional work was implemented, including the planting of native tree species in 2019 and fill planting
in 2022. A test plot survey was later conducted on the newly planted trees to determine the optimal
growing seedling strategies moving forward.
“OSSGA promotes excellence among its members by encouraging them to efficiently run their
operations, responsibly manage the land they work on, and actively participate in and contribute to
their communities,” says Norm Cheesman, Executive Director of OSSGA. “The 2022 Industry Recognition
Award winners have surpassed OSSGA’s expectation in fulfilling those objectives.”
