Generations of
building communities

Corliss Resources has been helping the Sumner community grow and prosper since 1892

For multiple generations, the Corliss family has owned and operated its mining facility at the base of the Sumner Grade, providing processed aggregate products to build and maintain much of the region’s vital infrastructure.


We at Corliss like to say we are in the business of building communities.

Almost everything we all enjoy in our community contains aggregate. All development or redevelopment activities are possible due to this important ingredient. Streets, sidewalks, parking lots, park trails, schools, churches, municipal buildings, and sewer utilities all exist due to aggregate. 

Without local suppliers, these resources would be considerably more expensive. Short shipping distances keep fuel costs down and reduce impacts to our already congested and deteriorating transportation system.

Planning for future generations

While the demand for processed aggregate is steadily increasing, several other mines in the area are reported to be closing, as they have exhausted their mineral resource reserves. Our solution to the challenge, Corliss Resources proposes an extension into an unused area adjacent to its existing mine as part of the company’s long-term planning effort.

our property

As we take the next step of applying for a conditional use permit and associated permits with Pierce County and the State for the Myers Road Mine, we invite our neighbors to learn more about the proposal and to participate in the approval process.


In 2015, Pierce County converted a retired mine in University Place to the world class Chambers Bay Golf Course, an achievement worthy of hosting the U.S. Open. Far in the future when aggregate is depleted, we look forward to inviting our local government and community to consult with us as we start the reclamation process. Working together to repurpose the land to a state that is appreciated and utilized by the community.


Myers Road will be reclaimed and filled with 85% dirt, and a small amount of inert material like crushed concrete or brick.

it is safe

Inert waste is not hazardous. Using it as landfill material is common practice, safe, and closely regulated.​

reduced carbon footprint

Our customer will be able to bring us backhaul inert waste material while picking up aggregate materials, thereby reducing empty truck loads on our already congested streets.

Our overall priority is respecting and protecting the community around us.

We have completed studies of potential noise, dust, traffic, and water resource impacts for the proposed Myers Mine project and will make changes to mitigation strategies as input from stakeholders comes in.
Corliss Resources will be good neighbors through good engineering and operating practices to comply with Pierce County’s strict noise standards.

Although mining and rock crushing can be loud at times, studies by Ramboll Engineering show large vegetated earthen berms along our East property lines will mitigate mining noise.
Corliss Resources is confident our aggressive dust suppression and management practices will ensure air quality standards will be met, and possibly exceeded.
We at Corliss have witnessed enormous urban growth in our region over the decades and share a concern with our neighbors about significant congestion caused by cross-city commuter traffic.

We are helping the City of Sumner develop a plan for a new roundabout interchange design proposed to be built mostly on land owned by the Corliss family.
Our studies show that mining activities will not impact groundwater, surface water, or storm water systems in any negative way. As a matter of fact, we foresee two positive outcomes:

Our expansion will result in a slight increase in groundwater recharge and additional seepage into Strawberry Creek.

And our systems will retain all stormwater on site to be treated and discharged into the ground.
From Kelley Farm to the hillside above Sumner, Corliss Resources has owned hundreds of acres of land in the Sumner/Bonney Lake area for generations. Holding ourselves accountable to environmental and private land stewardship has always been a key family value of ours.

We’d love to hear your comments or answer any questions you have about the Myers Road project.
