Why is a Phase I ESA different in Oakland, California?

There are a few reasons why a Phase I ESA (Environmental Site Assessment) might be different in Oakland, California than in other parts of the state.

  • History: Oakland has a long history of industrial activity, which means that there is a greater potential for environmental contamination on properties in the city. For example, Oakland was once home to a large number of manufacturing plants, which used a variety of hazardous chemicals. These chemicals can sometimes leak into the soil or groundwater, which can pose a health risk to people who live or work on the property.
  • Regional Environmental Concerns: Different regions may have varying environmental concerns based on their geography, historical land use, and industrial activities. In the case of Oakland, being located in the San Francisco Bay Area, there are specific regional concerns related to earthquake hazards, soil liquefaction, and potential impacts on water bodies such as the San Francisco Bay. A Phase I ESA in Oakland may take these factors into account and assess their potential impact on the site.
  • Regulations: The California Department of Toxic Substances Control (DTSC) has stricter regulations for environmental assessments in Oakland than in other parts of the state. This is because Oakland is considered to be a “hot spot” for environmental contamination. As a result, Phase I ESAs in Oakland must be more comprehensive than those in other parts of the state.
  • Cost: The cost of a Phase I ESA can vary depending on the size and complexity of the property, as well as the level of risk associated with the property. In Oakland, the cost of a Phase I ESA is typically higher than in other parts of the state due to the increased risk of environmental contamination.
  • Stakeholder Engagement: Oakland is known for its active community engagement and environmental advocacy groups. Stakeholders may have specific concerns about environmental justice, community health, or environmental impacts. Consequently, a Phase I ESA in Oakland may involve more robust community engagement and stakeholder consultation compared to other locations, ensuring that local concerns are adequately addressed.

If you are considering buying or selling a property in Oakland, it is important to have a Phase I ESA conducted by a qualified environmental professional. This will help to identify any potential environmental hazards on the property and protect you from liability in the future.

Here are some additional things to keep in mind about Phase I ESAs in Oakland:

  • The Phase I ESA must be conducted by a qualified environmental professional who is familiar with the DTSC regulations.
  • The Phase I ESA must include a review of historical records, a site inspection, and interviews with knowledgeable individuals.
  • The Phase I ESA must be completed within 90 days of the purchase or sale of the property.
  • The Phase I ESA must be reviewed by a DTSC-approved consultant.

Oakland’s local assessors share their take on what makes the area unique about assessments:

  1. Oakland’s industrial past poses a risk for communities as toxic waste — like petroleum, colorless gases, and flammable chemicals — rises with the groundwater due to climate change.
  2. The rising water table also poses a risk as unexpected plumes of toxic gases can vaporize and waft into the air in areas that weren’t previously tracked.
  3. San Francisco Bay Regional Water Quality Control Board is looking to impose regulatory actions, such as requiring stricter clean-up requirements and accelerating the timetable.

If you have any questions about Phase I ESAs in Oakland, you should consult with an environmental attorney or a qualified environmental professional.
