About the company
Clear Stone GEO LLC, a small business based in Spokane, Washington, performs geological surveying, drain maintenance and inspection, and water-infrastructure rehabilitation services for federal agencies as a prime contractor under total small business set-asides. The vendor has executed three purchase orders since July 2023, all at small-dollar values ($20 thousand to $140 thousand per award), with all three awards set aside for small business participation and all obligated dollars fully realized ($210 thousand combined).
Clear Stone GEO's federal footprint is distributed across three agencies with no customer concentration. The Department of the Army holds the largest single award at $139,750 for drain material removal at the William B. Hoyt II Visitor Center at Mount Morris Dam in New York (firm fixed price, completion date January 4, 2027). The Army Corps of Engineers awarded $20 thousand for camera inspections, cleaning, and decommissioning of drains at Howard A. Hanson Dam in Enumclaw, Washington (NAICS 221310 — Water Supply and Irrigation Systems, completion date March 26, 2025). The Department of the Interior Bureau of Land Management Nevada Region awarded $50 thousand for a BARNM Geological Inventory in Ely, Nevada under NAICS code for geophysical surveying and mapping (completion date April 30, 2024). Work scope clusters around water-infrastructure maintenance and geological survey services, reflected in top PSC codes Maintenance of Dams (two awards) and Special Studies/Analysis — Geological (one award).
Activity has been episodic — one award annually in 2023, 2024, and 2026 — with no observable growth trajectory or vehicle positioning. One award ($139,750 to the Department of the Army) reaches ultimate completion within the next twenty-four months and therefore faces recompete. Clear Stone GEO operates exclusively as a prime contractor (100% of awards) with no subcontract footprint in the source data. The vendor has not secured seats on any government-wide IDIQs, GWACs, or parent vehicles; all work to date flows through direct purchase orders.
