Yamabe & Horn Engineering

What Yamabe & Horn Engineering does

Yamabe & Horn Engineering, Inc. is a privately held civil engineering and land surveying firm founded in 1979 and headquartered at 2985 N. Burl Ave., Fresno, California. The firm employs 47 staff and operates as an integrated professional services practice rather than a product or platform business, delivering municipal engineering, commercial development, residential development, planning and entitlements, land surveying, and construction management and inspection under hourly and per-project billing. Gary Horn and Josh Rogers personally serve as City Engineer for at least eight Central Valley municipalities — Sanger (since 1987), Kerman (since 1993), Orange Cove (since 2001), Madera, Dinuba, Selma, Chowchilla, and Soledad — generating the majority of recurring revenue through long-term on-call contracts. The customer base also includes commercial enterprises such as Habitat for Humanity, Fowler Packing, Macerich, FedEx, and CVIN, alongside federal/military work at Camp Roberts.

The firm's technical stack is industry-standard: AutoCAD Civil 3D for design, GIS for asset mapping, GPS and robotic survey equipment for field work, a SCADA system for remote water-infrastructure monitoring, and trenchless technology (directional bore, microtunneling) for utility installation. Specialized credentials include Registered Engineers, Licensed Land Surveyors, Qualified SWPPP Practitioner, and a Certified Access Specialist (CASp) supporting ADA compliance services — a regulatory credential explicitly marketed against frivolous-ADA-litigation exposure for California businesses.

The business model is relationship-based government and developer services revenue. Geographic exposure is concentrated across Fresno, Madera, Tulare, Kings, and (more recently) Monterey counties, with no stated international footprint. Distribution is direct, via long-tenured City Engineer relationships and on-call contracts, supplemented by project case studies on the company website and limited organic social presence. Recent strategic activity centers on a leadership transition (Derek Lapsley promoted to VP of Operations in December 2024), geographic expansion into Monterey County, and a notable entry into telecommunications infrastructure design via the $66M Central Valley Next-Generation Broadband project.

Broad incumbents

• Stantec: Global engineering, architecture, and environmental services firm with California offices serving municipal water, infrastructure, and land development clients. Represents the type of large incumbent that competes with and sometimes partners with smaller Central Valley firms.
• AECOM: Global infrastructure consulting firm with deep California public works presence including transportation, water, and environmental services. Competes for the largest infrastructure programs in the state and serves many of the same municipal and state agency clients as Y&H.
• Michael Baker International: National engineering, planning, and consulting firm with California offices serving transportation, water, and municipal infrastructure clients. Comparable service mix to Y&H but at significantly larger scale, often participating in regional programs that Y&H supports as a sub-consultant.
• Kimley-Horn: Large national engineering, planning, and consulting firm with a significant California presence including offices serving Central Valley and Sacramento markets. Competes for larger municipal and private development contracts that exceed Y&H's scale, and increasingly partners with smaller firms on mega-projects.

Regional players

• Psomas: California-headquartered (Los Angeles) civil engineering, surveying, and environmental services firm. Comparable service lines and private/municipal client mix, with strong California presence but different geographic concentration (Southern California rather than Central Valley).

Highly comparable headcount, geographic footprint, and service mix including municipal engineering, water resources, and land development.
