What Luhdorff & Scalmanini Consulting Engineers does

Luhdorff & Scalmanini Consulting Engineers (LSCE) is a privately held California-based consulting engineering firm founded in 1980 by Eugene E. Luhdorff Jr. and Joseph C. Scalmanini, headquartered in Woodland, CA, with additional offices in Roseville, Daly City, Chico, and Boise/Meridian. The firm delivers specialized groundwater resources consulting and engineering services to municipalities, water districts, groundwater sustainability agencies (GSAs), county governments, sanitation districts, and agricultural operations across California, Idaho, Oregon, and Utah, with primary demand drivers being California's Sustainable Groundwater Management Act (SGMA) compliance cycle and municipal water infrastructure needs.

LSCE operates across six integrated service lines: Groundwater Resources (SGMA compliance, GSP development, conjunctive use, aquifer storage and recovery), Wells & Pump Stations (planning, permitting, design, and construction management), Treatment/Storage/Distribution (water treatment and distribution engineering), Environmental (groundwater quality investigations), Modeling (conceptual, analytical, empirical, and numerical hydrologic modeling using platforms such as IWFM, MODFLOW One-Water, and MT3D-USGS), and Data Management Systems (database design, visualization, GIS integration). The firm differentiates through proprietary methodologies including a representative groundwater monitoring approach for the Central Valley dairy industry that delivered approximately $50 million in community cost savings.

The business model is project-based professional services consulting with fees negotiated per engagement, employing approximately 50-60 professionals including licensed engineers, geologists, hydrogeologists, and hydrologists. GTM motion is direct enterprise/government field sales targeting water utilities, counties, and regulatory bodies, with client relationships commonly spanning 10-30+ years. The firm has completed over 3,000 projects cumulatively and currently manages 150+ active engagements. No external funding, M&A, or public listing has been disclosed.
