Heidelberg Materials Gold Bar operations
As of January 2023, Lehigh Hanson and the majority of their affiliated North American brands, including Cadman, transitioned to unify under one brand: Heidelberg Materials.
Heidelberg Materials Pacific Northwest currently operates a sand and gravel mine in Gold Bar, Washington that has been in operation since 2005. Sand and gravel from the existing mine have been used in local projects and Heidelberg Materials expects quarry rock to be utilized in local construction and transportation projects. This operation employs four individuals from the local community and an additional six who live in Snohomish County.
Proposed Expansion Project
Heidelberg Materials seeks to operate a new hard rock quarry to the south of its existing sand and gravel mine (See Figure 1). The overall goal for this new mine is to extract hard rock material for local use as road base, rip rap for shoreline and dike protection, and as landscaping rock. Heidelberg Materials is dedicated to ensuring environmental and public health and providing economic opportunities for residents of Gold Bar during operations.
The new hard rock mine will extract high quality volcanic rock from a 25 to 30-acre quarry. A haul road and or conveyance system will move rock west to the proposed processing area. The total volume of the material mined is expected to be 15 to 20 million tons at a rate of 0.5 million to 1.0 million tons per year.
