What Environmental Consultants Do
Environmental issues can delay closings, impact financing, and introduce liability into a project. Environmental consultants evaluate environmental risk associated with real estate, development, and operational properties. Our role is to identify potential contamination, assess regulatory requirements, and provide clear guidance on next steps.
We work alongside clients during critical decision points, delivering assessments that are not only technically sound, but directly aligned with project timelines, deal structure, and regulatory requirements.
When Environmental Services Are Required
Environmental services are typically required when a property is being evaluated for risk, financing, or regulatory compliance.
Common scenarios include:
Commercial property acquisition or sale
Financing or refinancing through a lender
Redevelopment or change in property use
Regulatory requirements or agency involvement
Identification of contamination or environmental concerns
Building issues such as mold, odor, or indoor air quality complaints
In these situations, environmental due diligence helps protect buyers, lenders, and property owners from liability and unexpected costs.

Commonly Asked Questions
What is a Phase I Environmental Site Assessment?
1
A Phase I Environmental Site Assessment is a due diligence report conducted to evaluate potential environmental risks associated with a property. It involves a review of historical records, regulatory databases, site conditions, and surrounding land use to identify recognized environmental conditions (RECs). Phase I ESAs are commonly required by lenders and are performed in accordance with ASTM E1527-21 standards to support liability protection under the EPA’s All Appropriate Inquiry (AAI) rule.
When is a Phase II ESA required?
2
A Phase II Environmental Site Assessment is recommended when a Phase I ESA identifies a recognized environmental condition that warrants further investigation. This typically involves soil, groundwater, or vapor sampling to confirm whether contamination is present, determine its extent, and evaluate potential risk to human health or the environment. Phase II scopes are developed based on the specific findings of the Phase I.
How long do environmental reports take?
3
Phase I Environmental Site Assessments typically take 2 to 4 weeks to complete, depending on property complexity, records availability, and site access. Expedited timelines may be available for time-sensitive transactions. Phase II ESA timelines vary based on the scope of work, including sampling requirements, laboratory analysis, and site conditions, but generally range from a few weeks to several months.
Who typically needs a Phase I Environmental Site Assessment?
4
Phase I ESAs are typically required by lenders, real estate investors, developers, and property owners involved in commercial real estate transactions, refinancing, or redevelopment projects. They are used to assess environmental risk prior to acquisition and to qualify for liability protections under federal regulations. Even when not required, many buyers choose to complete a Phase I ESA to avoid unexpected environmental liabilities and delays during closing.
