• VHB: Northeast-focused engineering, planning, and environmental consulting firm with strong NY presence. Directly comparable on environmental impact assessment, comprehensive planning, wetlands, and transportation-oriented development work.
• AKRF: Large NY-based environmental planning, engineering, and construction services firm. Direct competitor on SEQRA/NEPA review, environmental impact statements, waterfront revitalization, and municipal planning across the New York metro and Hudson Valley regions.
• Cameron Engineering & Associates: Long Island-based engineering, planning, and environmental firm. Direct competitor on Long Island for municipal planning, SEQRA review, waterfront work, and infrastructure consulting for towns and villages.
• C.T. Male Associates: Upstate New York engineering, environmental, and land surveying firm. Competes with NPV in SEQRA compliance, site assessment, surveying, and municipal infrastructure planning, though with a different geographic center of gravity.

Broad incumbents

• Arcadis: Global design, engineering, and environmental consulting firm. Active across NY in resilience, water, and environmental advisory; competes with NPV on larger municipal and developer-led planning and environmental review programs.

Emerging players

• Roux Associates: Northeast environmental consulting firm specializing in site investigation and remediation. Overlaps with NPV's Phase I/II ESA and brownfield practice, though more focused on remediation delivery than planning.
