Greg Ainsworth

As Principal Manager of Environmental Services at Bancroft Construction Services, Greg brings over 20 years of specialized expertise in biological resource management, regulatory permitting, and environmental compliance across both public infrastructure and private development sectors. His work is centered on ensuring the protection of sensitive habitats and species while aligning construction timelines with complex regulatory frameworks.

Greg holds a Master’s in City and Regional Planning and a Bachelor of Science in Environmental Horticulture from California Polytechnic State University, San Luis Obispo. Greg has built a career at the intersection of ecological science, environmental policy, and practical field application. He is a Certified Arborist with the International Society of Arboriculture, with extensive experience in urban forestry, including large-scale tree inventories, risk assessments, and integrating tree protection standards into development planning.

His technical expertise spans both coastal and desert ecosystems with a wide range of environmental disciplines, including:

• Biological resource assessments and focused species surveys
• Wetland delineations and jurisdictional determinations
• Habitat restoration and conservation planning
• Regulatory permitting (Endangered Species and Jurisdictional Waters)
• Construction compliance monitoring and contractor coordination
• Technical writing for impact assessments, permit packages, and mitigation plans

Greg is well-versed in interpreting and implementing environmental regulations, including the California Environmental Quality Act (CEQA), National Environmental Policy Act (NEPA), Endangered Species Act, and Clean Water Act. His leadership ensures that environmental compliance is embedded throughout all project phases—from early design and permitting through active construction and final closeout.

At Bancroft Construction Services, Greg leads interdisciplinary teams to support biological and cultural resource surveys, permitting strategies, and agency coordination. He serves as a liaison between Subject Matter Experts, engineers, planners, and regulatory bodies, helping clients meet environmental obligations without compromising on project delivery. He also provides invaluable insight into Bancroft’s Restoration Services on restoration ecology, horticulture, and mitigation compliance for restoring ecological habitats and suppressing noxious weeds on project sites.

Passionate about sustainable land development and ecological integrity, Greg strives to bring practical, science-based solutions to the challenges of building in sensitive natural environments.
