JOHNSON-MCADAMS SURVEYING & MAPPING LLC

JOHNSON-MCADAMS SURVEYING & MAPPING LLC specializes in precise geospatial surveying and mapping services tailored to federal infrastructure and land management needs. The firm delivers high-accuracy boundary surveys, topographical mapping, riverine cross-section analyses, and levee enhancement surveys using modern geodetic instrumentation and GIS-integrated workflows. Their technical expertise includes cadastral surveying, hydrographic boundary delineation, floodplain mapping, and emergency survey response for riverine and coastal defense projects, particularly along the Mississippi and Saint Francis River systems. The company’s differentiation lies in its focused execution of complex, time-sensitive missions for military and civil works projects, ensuring compliance with Army Corps of Engineers standards and federal land acquisition protocols. The contractor maintains a consistent, long-standing relationship with the Department of Defense, providing critical surveying and mapping support for installation expansion, flood control infrastructure, and real property acquisitions. Their work directly enables military readiness through accurate land boundary determination, easement documentation, and river revetment assessments required for infrastructure resilience and environmental compliance. Operating under NAICS 541370, the firm is deeply embedded in the defense and civil works surveying market, delivering non-geophysical geospatial services essential to infrastructure planning, environmental permitting, and emergency response. Their vertical specialization centers on riverine and levee systems, positioning them as a trusted provider for dynamic hydrologic boundary mapping in high-risk flood zones. As a small business structured as a 2L entity based in Greenwood, Mississippi, JOHNSON-MCADAMS operates with regional expertise and federal contract agility. While not certified under federal small business programs, the company leverages its localized knowledge and technical precision to serve defense and civil engineering clients across the Mississippi River basin and beyond.
