What is a Phase II Environmental Site Assessment?

A Phase II Environmental Site Assessment (ESA) is a study conducted to identify any potential environmental contamination at a property. This type of assessment is typically conducted when there is reason to believe that the property may be contaminated, such as when there has been a release of hazardous materials nearby or when the property has been used for industrial purposes in the past.

The Phase II ESA involves collecting samples of soil, water, and air from the property and testing them for the presence of hazardous substances. If any contamination is found, the Phase II ESA will also assess the risk to human health and the environment. Based on the findings of the assessment, appropriate remediation measures can be taken to clean up the contamination and protect people and wildlife from exposure.

What Does a Phase II ESA Include?

A Phase II ESA typically includes the following:

-An investigation of the site’s history and current condition
-A review of environmental regulations that apply to the property
-An assessment of potential environmental liabilities associated with the property
-A determination of whether further investigation is warranted

The purpose of a Phase II ESA is to gather enough information to make an informed decision about whether or not to proceed with a particular transaction. The investigation should be thorough and objective, and it should be conducted by a qualified environmental professional.

How Much Does a Phase II ESA Cost?

The cost of a Phase II Environmental Site Assessment (ESA) in Oakland, California can vary depending on the size and scope of the project. However, the average cost for a Phase II ESA in Oakland is $4,000 – $5,000.

A Phase II ESA is typically conducted after a Phase I ESA has been completed and potential contamination has been identified. The purpose of a Phase II ESA is to collect samples of soil, water, and/or air to determine if there are any contaminants present at the site.

Phase II ESAs can be conducted using a variety of methods, including hand augering, direct push sampling, and sub-slab soil gas sampling. The type of method used will depend on the specific needs of the project.

The cost of a Phase II ESA will also depend on the number of samples that need to be collected. For example, a small site with only one potential source of contamination may only require 10-20 samples, while a larger site with multiple potential sources of contamination may require 50-100 samples.

If you are considering conducting a Phase II ESA at your property in Oakland, California, contact several environmental consulting firms to get quotes for the project.

When Should You Get a Phase II ESA?

There are a few key things to keep in mind when considering whether or not to get a Phase II Environmental Site Assessment (ESA) in Oakland. First, if you are planning on buying or selling a property, it is generally required in order to obtain title insurance. Second, if you are leasing a property for commercial use, your lender will likely require a Phase II ESA as part of the loan process. Finally, if there is reason to believe that the property may be contaminated (for example, there was previously a gas station on the site), then a Phase II ESA may be necessary.

How Long Does a Phase II ESA Take?

A Phase II ESA can take anywhere from a few weeks to a few months to complete. It all depends on the size and scope of the project, as well as the availability of data and personnel. Typically, a Phase II ESA will involve the following steps:

1. Data Collection: This step involves collecting all relevant data related to the property, including historical records, current environmental conditions, and any previous environmental assessments that have been conducted.

2. Site Investigation: This step involves conducting an on-site investigation to assess current environmental conditions and identify any potential contamination sources.

3. Analysis and Reporting: This step involves analyzing all collected data and preparing a report detailing the findings of the investigation.

Why Choose Oakland for Your Phase II ESA?

When Phase II Environmental Site Assessments (ESAs) are conducted, the focus is on determining the presence or absence of contamination in soil and/or groundwater. Oakland, California is an ideal location for Phase II ESAs due to its diverse geology and large population.

The Oakland area is underlain by a variety of geological materials, including sedimentary rocks (sandstone, shale, and limestone), metamorphic rocks (gneiss and schist), and igneous rocks (basalt and granite). This diversity provides a natural laboratory for testing different approaches to Phase II ESAs. In addition, the large population in Oakland creates a demand for Phase II ESAs, making it easier to find qualified firms to conduct the assessment.

Oakland also has a long history of environmental contamination, dating back to the early days of industrialization in the 19th century. This history has resulted in a wealth of data on environmental conditions in the area, which can be used to evaluate potential sites for contamination. Additionally, many of the areas that have been contaminated in the past have been remediated, providing valuable lessons on how to clean up sites that are contaminated.


Overall, the Phase II Environmental Site Assessment for Oakland was very positive. There were no significant environmental concerns found at the site, and it appears to be suitable for future development. We recommend that you proceed with your plans for development at this site. Thank you for choosing Oakland as your development location!
