What PLSA Engineering & Surveying does

PLSA Engineering & Surveying is a privately held Washington Corporation headquartered in Yakima, Washington, providing civil engineering, geotechnical engineering, land surveying, land planning, environmental services, materials testing, and construction quality control services. Founded in 1964 by Preston Shepherd (originally operating as Preston L. Shepherd & Associates, Inc., with the PLSA Engineering & Surveying trade name adopted in 1987), the firm has completed thousands of projects over six decades for clients throughout the State of Washington. Its service portfolio is delivered through five integrated lines (Civil Engineering, Geotechnical Engineering, Surveying, Land Planning, and Quality Control) using industry-standard tools including AutoCAD Civil 3D and Leica Survey equipment, supported by licensed Professional Engineers and Professional Land Surveyors and long-tenured technical staff.

The firm serves a diversified client base including city and county governmental agencies, school districts, utility districts, contractors, consultants, and private sector developers (residential, commercial, and agricultural). Named engagements span small local developers (Columbia Ridge Homes, Hannon Heights, Zillah Lakes), mid-sized businesses (Hapo Credit Union, Matson Fruit, Catalyss Development), and larger commercial clients (JC Penny). The Yakima-based office is the sole location, with field crews deployed to project sites across Washington State. Go-to-market is primarily direct client engagement, supplemented by a limited digital presence on LinkedIn, Facebook, and the company website, with no disclosed partnerships, marketing campaigns, or external investment.

Revenue is generated through fees for professional services on a project/quote basis; no pricing, revenue figures, or financial performance metrics are publicly disclosed. The firm operates as a small professional services practice (11-50 employees) with no venture capital, private equity, or institutional investment indicated. Ownership and management are led by Principal Engineer Scott Garland, PE, and Principal Surveyor Joe Baker, PLS, supported by department-level managers across survey, CAD, planning, and operations functions.
