Emmons & Olivier Resources

What Emmons & Olivier Resources does

Emmons & Olivier Resources, Inc. (EOR) is an employee-owned (ESOP), multi-disciplinary environmental and engineering consulting firm headquartered in Saint Paul, Minnesota, with additional offices in Madison (WI), Boone (IA), and three Canadian locations (Edmonton, Calgary, Red Deer) operating under EOR Canada, which was established in 2018. The firm serves U.S. and Canadian municipalities, watershed districts, state and federal agencies, utilities, renewable energy developers, and private landowners through eight integrated service lines: Civil Engineering, Ecological Restoration, Energy & Utilities, Environmental Reviews, GIS & Drone Technology, Landscape Architecture, Planning & Guidance, and Water Resources Engineering. Its work spans streams, lakes, wetlands, prairies, and forests, with a portfolio that includes 400+ solar/wind farms, 300+ substations, 600+ utility corridors, and large-scale watershed retrofits (e.g., 85,000 LID opportunities identified for the City of Edmonton).

EOR generates revenue through project-based professional service fees earned under direct consulting engagements and RFP-driven contracts with public agencies. The firm's go-to-market is enterprise field sales targeting long-cycle public sector clients (Minnesota DNR, U.S. Forest Service, U.S. Army Corps of Engineers, multiple watershed districts, and Canadian municipalities), supported by thought-leadership content (LinkedIn, Vimeo, academic presentations, ACEC Podcast) and participation in industry conferences such as Midwest Solar Expo and CleanPower. Pricing is quote-driven and not publicly disclosed. The firm is organized around three pillars — Water, Ecology, and Community — each led by a dedicated Practice Lead, with overall operational leadership provided by a newly appointed Chief Operating Officer.

Technically, EOR distinguishes itself through pairing of multiple hydrologic and hydraulic models (HECRAS, XP-SWMM, RIVERMorph, CONCEPTS) for stream restoration work, custom mobile data collection applications for aquatic plant surveys and natural resource assessments, and integrated use of GIS and drone technology for surveying, mapping, and project documentation. The firm holds no disclosed patents and reports no AI/ML-native capabilities; its differentiators are domain specialization, regulatory expertise across multiple jurisdictions, and project portfolio scale rather than proprietary technology. Notable quantified outcomes include approximately $30M in infrastructure cost savings through a zero-discharge stormwater system for Inver Grove Heights and $2.5M in savings via community raingardens, alongside multiple ACEC national and FDIC Engineering Award of Merit recognitions.
