Sligh Environmental Consultants

What Sligh Environmental Consultants does

Sligh Environmental Consultants, Inc. (SECI) is a privately held, founder-led natural resources environmental consulting firm headquartered in Savannah, Georgia, serving clients across the Southeastern United States — primarily Georgia, South Carolina, Alabama, and North Florida. The firm provides professional environmental services to private developers, water and sewer utilities, municipalities, transportation departments, engineering consulting firms, aggregate mining groups, and private landowners with large holdings. SECI's core practice is wetlands determination and permitting for large-scale master planned developments, supplemented by marina and dock permitting, endangered species management plans, red-cockaded woodpecker and eastern indigo snake surveys, and GIS-based natural resources inventory mapping for large land owners.

The firm operates a professional services model with quote-based project fees scaled to scope, size, and complexity. In parallel, SECI generates recurring revenue through the management of three wetland and stream mitigation banks in Georgia (Black Creek in Bulloch County, Rose Creek in Oconee County, and Magnolia Swamp), with additional banks in the final stages of regulatory agency approval. Credit sales from these mitigation banks to developers requiring compensatory offsets create a managed-services revenue stream alongside consulting fees. Project sizes range from 1-acre residential lots to over 5,000 acres of undeveloped waterfront property.

SECI's underlying technology is centered on Geographic Information Systems (GIS) for natural resources inventory, supplemented by deep regulatory expertise and longstanding relationships with federal, state, and local resource agencies. The staff includes specialists in wildlife biology, timber management, marine geology, environmental economics, and forest business. The firm is privately held, with no disclosed outside investors, no funding rounds, and no M&A activity; Stuart F. Sligh serves as President. Distribution is direct, sales-led, and relationship-based, with the company website serving as the primary public-facing channel rather than traditional marketing.
