Phase I Environmental Site Assessment (ESA)

A Phase I Environmental Site Assessment is a critical first step in evaluating commercial property for potential environmental contamination and liabilities. This comprehensive investigation documents the property's history, current conditions, and any recognized environmental conditions (RECs) that could affect development, financing, or future liability. 

What is a Phase I ESA?

A Phase I ESA is a non-invasive environmental due diligence process that evaluates a property's potential for environmental contamination through historical research, site observation, and interviews. It identifies whether further investigation (Phase II testing) is warranted before you proceed with acquisition, financing, or development. 

Our Phase I ESA Services Include

Historical Research - We investigate the property's ownership history, previous industrial uses, and occupancy records. This research reveals past activities that may have left environmental impacts, even if the property has changed hands multiple times.

Records Review - We examine regulatory databases, fire department records, health department files, and environmental agency databases to identify any documented environmental violations, spills, or contamination on or near the property. 

Regulatory Database Searches - We conduct comprehensive searches of federal, state, and local environmental databases to identify nearby contaminated sites, underground storage tanks, and regulatory compliance issues that could affect your property.

Site Inspection - Our team conducts a thorough visual inspection of the property, building systems, storage areas, and surrounding land to identify potential environmental concerns, hazardous materials, or conditions requiring further investigation.

Interviews - We interview current and former property owners and occupants to gather firsthand knowledge of past operations, chemical use, waste disposal practices, and any known environmental issues.

Report and Recommendations - We provide a detailed Phase I ESA report documenting findings, identified RECs, and recommendations for next steps, including whether Phase II subsurface testing is necessary.

Why a Phase I ESA Matters

A Phase I ESA protects your investment by identifying environmental liabilities before they become costly problems. Lenders typically require a Phase I ESA before financing commercial real estate. Early identification of potential contamination can influence purchase negotiations, guide development planning, and protect you from inheriting environmental cleanup costs.
