What Soltesz does

Soltesz is a multi-disciplinary civil engineering and land development firm headquartered in Rockville, Maryland, with additional offices in Lanham and Waldorf. Founded in 1980 and celebrating 45 years of operation in 2025, the firm serves public sector clients (federal, state, and county governments) and private sector developers across Maryland, Washington D.C., and Northern Virginia. It offers an integrated suite of services spanning civil engineering, environmental and water resources, landscape architecture, entitlements, permitting, planning, surveying, GIS, peer review, construction administration, design-build, due diligence, and roadway design, allowing projects to be delivered from site feasibility through construction under a single-vendor model.

The firm operates a project-based professional services revenue model on competitive bids, RFPs, RFP responses, and direct enterprise sales, with VPs and General Managers directly managing key client relationships. Its technology stack is built on standard civil engineering platforms (AutoCAD, Civil 3D, Microstation, Hec-Ras, Hydraflow) supplemented by proprietary GIS-enabled corridor analysis capabilities used for large-scale infrastructure studies such as the Montgomery County Bus Rapid Transit corridor analysis. Notable signature projects include the $2.8 billion, 280-acre Viva White Oak bioscience village (Montgomery County), the 600,000 sq. ft. University of Maryland Capital Region Medical Center (ENR Best Health Care award, 2021), the 1.2 million sq. ft. U.S. Coast Guard Headquarters with 400,000 sq. ft. of green roof stormwater design, the 500+ acre National Harbor mixed-use waterfront, and the 154-acre Riderwood Village senior living community.

Customer concentration is spread across multiple enterprise verticals including life science real estate (Global LifeSci Development Corporation, Alexandria Realty), senior living (Erickson Living, Kisco Senior Living), residential development (Stanley Martin, ZOM Living), mixed-use developers (Peterson Companies, Calvin Cafritz Enterprises, JBG Companies), healthcare (University of Maryland Medical System), and government agencies (GSA, St. Mary's County, Prince George's County). The firm is closely held under the Soltesz family, with James Soltesz as President and CEO and Kyle Soltesz leading MBIA Montgomery County Chapter, and maintains active influence in county regulatory processes through board and committee positions.
