About the company
Alluvion Biological Consulting LLC, doing business as United 2 Connect International, is a minority-owned, Black American-owned small disadvantaged business and certified Disadvantaged Business Enterprise based on available data, operating predominantly as a subcontractor (80% of recent awards) on civil engineering and environmental consulting projects for federal water resource and infrastructure agencies. The vendor is a Subchapter S corporation with no named headquarters location in the source.
Alluvion's capability footprint centers on biological monitoring, environmental surveys, and compliance reporting for levee construction, dredging, and stream restoration projects. Recent work includes monitoring and reporting for the REACH 6 Levee and Floodwall construction along Corralitos Creek in Watsonville, California; fish screen and water monitoring for the Sacramento Deep Water Ship Channel FY25 maintenance dredging project; eel grass credit and herring monitoring work on the Sacramento River system; and biological monitoring and pre-construction surveys on Sacramento River erosion projects. Work is geographically concentrated in California water infrastructure.
Customer concentration is diffuse across Corps of Engineers districts and the Department of the Interior. The Department of the Army Corps of Engineers (counting both the main bureau and subordinate Sacramento and San Francisco districts) appears across three of five awards, while the Department of the Interior Bureau of Land Management California Region accounts for one award carrying a $24 thousand potential value. The top customers by award count represent 80% of the five-award portfolio, with no single customer dominating volume.
Alluvion subcontracts primarily to The Dutra Group on dredging and levee projects and to San Rafael Rock Quarry, Inc. on river erosion work. Award activity is sparse — one award in 2019, one each in 2023 and 2024, and two in 2025 — with combined potential value of $24 thousand against combined obligated dollars of $335 thousand, indicating executed work at scales above contract ceiling values.
