What Spangler Environmental does
Spangler Environmental, LLC (SEL) is a Raleigh, North Carolina-based environmental consulting firm founded in 1999 by Jim Spangler, providing environmental risk management, natural resources, and litigation support services to land developers, home builders, civil engineers, architects, attorneys, financial institutions, and government agencies across the Southeast and Mid-Atlantic United States. Services are organized into three practice areas: Risk Management (Phase I, II, and III Environmental Site Assessments compliant with ASTM E1527-13, Property Condition Assessments, Radon testing, and contaminated-site remediation construction management), Natural Resources (wetland and stream delineations per US Army Corps of Engineers standards, 404/401 and Riparian Buffer permitting, restoration, NPDES erosion-control inspections, and Endangered Species Act protected species work), and Litigation Support (expert testimony in NC OAH, civil superior courts, and federal courts, plus exhibit preparation, regulatory compliance inspections, and public-hearing support). Deliverables are produced using field biology, ecology, geology, hydrology, and soil pedology expertise.
The firm operates on a project-based professional services model with direct, relationship-driven client engagement and quote-based project pricing; no standard pricing tiers are publicly disclosed. Spangler has performed work in twelve U.S. states (NC, SC, VA, GA, TN, MD, FL, PR, MI, MS, DC, NJ) and reports having permitted 40,000+ residential lots, approved 1,000+ wetland delineations with the US Army Corps of Engineers, authored 2,000+ environmental compliance reports, and confirmed 500+ NC DWR Riparian Buffer stream origin delineations. Major enterprise clients include Lennar, M/I Homes of Raleigh, Hamilton-Merritt, and Hamlet & Associates PLLC, and the firm states it is environmental consultant of record for nearly all of the ten largest home builders in its region. Distribution relies on direct enterprise sales, professional referrals, industry association memberships (NAEP, NAHB, NCHBA, ASCE, NCAEP), and thought leadership via webinars and conference participation.
In March 2025, Spangler Environmental was acquired by Earth Systems, a Jacksonville Beach, Florida-based environmental consulting firm backed by private equity sponsor Palm Beach Capital. Jim Spangler transitioned to president of the Spangler Environmental unit within Earth Systems. Post-acquisition, Spangler operates as a unit within the Earth Systems family of companies, alongside newly added partners Bio-Tech Consulting (Orlando), EnviroTrac (Northeast/Midwest), and Envirotactics (New Jersey), collectively executing a multi-firm roll-up of regional environmental consultancies under PE ownership.
