WASHINGTON ROCK QUARRIES, INC.

Washington Rock Quarries, Inc. specializes in the extraction, processing, and delivery of natural stone and aggregate materials for critical infrastructure restoration and environmental mitigation projects. Their technical expertise centers on sourcing and supplying high-performance rock materials suited for hydraulic structures, erosion control, and aquatic habitat rehabilitation—particularly in flood-impacted watersheds. The company’s capability is demonstrated through the provision of engineered fill and riprap for the Mud Mountain Dam Fish Passage Facility, where material integrity and sediment compatibility are essential to restoring natural stream dynamics and supporting native fish migration. Their specialization lies in matching geological properties to hydraulic engineering requirements, ensuring long-term stability under high-flow conditions and ecological compatibility. The contractor has delivered materials to the U.S. Army Corps of Engineers via the W071 Endist Seattle contracting office, indicating a focused relationship with federal civil works and environmental restoration programs. Their work supports infrastructure resilience initiatives tied to flood recovery, dam safety, and aquatic ecosystem repair—areas requiring precise material specifications and timely logistics in sensitive environmental zones. Washington Rock Quarries operates under NAICS 212319, which classifies them as a nonmetallic mineral mining and quarrying firm specializing in construction aggregates. This places them squarely within the civil engineering supply chain for federal infrastructure projects, particularly those involving dam maintenance, streambank stabilization, and fish passage enhancements. Their market positioning is niche but vital: they serve as a trusted source of geotechnically certified rock for federal hydraulic projects requiring material traceability and structural performance under dynamic water loads. As a small business structured as a 2L entity, Washington Rock Quarries is locally based in Orting, Washington, with operations tailored to the Pacific Northwest’s unique geology and environmental regulations. While no federal certifications are listed, their ability to deliver mission-critical materials for U.S. Army Corps projects demonstrates compliance with federal quality and environmental standards. Their geographic proximity to key infrastructure sites enables rapid response to emergency restoration events.
