Generations of
building communities


Corliss Resources has been helping the Sumner/Bonney Lake 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.

So much of what we value in our communities starts with aggregate: whether it is the foundation or patio for your home, school, office or favorite coffee stand; the parking lot for your grocery store; or the trail that you walk on to recreate – these all exist due to aggregate.


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 due to exhaustion of their resource reserves. As a solution to the challenge, Corliss Resources proposes mining 146 acres adjacent to the existing Sumner mine. We invite our neighbors to learn more about the Myers Road Mine proposal and to participate in the approval process.

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.

Corliss Resources will be good neighbors through recognized engineering and operating practices to comply with Pierce County’s strict noise standards.

• Noise study shows vegetated 12-14’ tall earthen berms will protect neighbors from noise.

• Noise modeling confirms that berms will ensure compliance with County noise standards ensuring that there is not a significant increase in noise for our neighbors.
We are confident our aggressive dust suppression and management practices will ensure air quality standards will be met. Best management practices will include:

• Reducing dust by maintaining slow vehicle speeds and wetting internal haul roads.

• Covering truck loads.

• Maintain vegetation in project perimeter buffer.
We at Corliss Resources share a concern with our neighbors about significant congestion caused by cross-city commuter traffic and growth in our area.

• Corliss Resources is collaborating with the City of Sumner and others to develop a new Sumner-Tapps Highway-SR410 interchange to be built mostly on land owned by the Corliss family.

• Studies show minimal traffic impact on Myers Road because material will be conveyed to our existing Sumner facility for processing.
Our studies show that mining activities will not adversely impact groundwater, surface water, or storm water systems.

• Stormwater will be treated and infiltrated on-site.

• The Myers Road MIne should not capture groundwater which is contributing to drinking water supply wells in the area.

• The proposed stormwater system may slightly increase spring flow rates that source Strawberry Creek, a tributary of Salmon Creek, benefiting fish habitat.

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