Phase 1 Environmental Site Assessments (ESAs)

A due-diligence look at a property's environmental history before you commit

A phase 1 environmental site assessment reviews a property's history and current conditions to identify potential environmental concerns without sampling. Colman Engineering conducts phase 1 ESAs across Virginia for buyers, lenders, and developers who want to understand the environmental risk associated with a property. The result is a report that flags recognized environmental conditions and gives you a clearer basis for decision-making.

Benefits

Phase 1 Environmental Site Assessments (ESAs)

Informed decisions before closing

A phase 1 gives you a clearer picture of a property's environmental history before money changes hands. That knowledge can shape negotiations, financing, and your plans for the site.

Aligned with recognized standards

We conduct assessments consistent with the widely used ASTM practice for phase 1 ESAs, supporting lender requirements and standard due-diligence expectations.

Straight answers, clearly reported

We explain the findings and their practical significance in plain language. If further investigation is warranted, we explain why and what it would involve.

A structured review of records, history, and site conditions

We research the property's history through records, aerial photographs, and regulatory databases, and we walk the site to observe current conditions. We also interview people familiar with the property where possible. All of this comes together in a report identifying any recognized environmental conditions and our professional opinion on them. If we find something that warrants a closer look, we explain what a phase 2 investigation would involve so you can decide how to proceed.

Use Cases

A phase 1 ESA is often the right first step when a property is changing hands or use.

01

You're buying commercial or industrial property

You want to understand environmental risk before closing on a purchase. A phase 1 is the standard due-diligence tool for exactly this moment.

02

A lender is requiring it

Your financing depends on environmental due diligence. We prepare phase 1 reports that speak to those lender expectations.

03

The site has an industrial or commercial past

Prior uses like fueling, manufacturing, or dry cleaning raise questions. A phase 1 helps document that history and whether it warrants further study.

Tips and FAQs

A phase 1 involves no sampling; it's a records-and-observation review that identifies whether concerns exist, not the extent of any contamination. If it flags a recognized environmental condition, the logical next step is a phase 2, which does involve sampling. phase 1 reports also have a shelf life for due-diligence purposes, so timing the work close to your transaction matters.

Does a phase 1 involve soil or water testing?

No. A phase 1 is a non-intrusive review of records, history, and observable conditions. Sampling only happens in a phase 2, if the phase 1 indicates it's warranted.

How long is a phase 1 report considered current?

Under the common ASTM standard, key components are generally viewed as current for a limited window before a transaction. We can advise on timing so your report stays useful for your closing.

What happens if you find a concern?

We document it as a recognized environmental condition and explain its potential significance. If further investigation is warranted, we outline what a phase 2 would involve.

Who typically orders a phase 1?

Buyers, lenders, and developers most often, usually as part of due diligence. We're glad to coordinate with whichever party needs the report.
