Why Phase I ESAs Are Unique in San Diego

Phase I Environmental Site Assessments (ESAs) in San Diego, California are different from other states in the country for a variety of reasons. The San Diego area has a unique and rich history that sets it apart from most other locations. San Diego has been a development hub for decades, with no significant slow in growth. Environmental due diligence and development goes hand in hand; so, where development goes, we follow!

Selecting an environmental consulting firm that is familiar with these factors is key in ensuring thorough and quality Phase I ESAs. See below for what it is that makes environmental due-diligence practices in San Diego so unique:

  • Military Presence: San Diego is arguably most known for their military presence, both active and historical. Military practices, such as training, manufacturing, testing, etc., can greatly impact the environment, thus impacting how Phase I ESAs are written for the area. Though a lot of the issues associated with military activities in the area have been addressed by the local regulatory agencies, they require discussion and need to be addressed throughout the Phase I reporting process.
  • Developmental History: San Diego has deep-rooted history in development, dating back to the 1800s and earlier in many locations. Prior to the Resource Conservation Recovery Act (RCRA) of 1976, which initiated the tracking and management of hazardous materials from “cradle to grave,” facilities operated with little to no oversight regarding hazardous materials management and disposal practices. Because of this, it is not uncommon for Phase I ESAs to uncover former environmental issues (i.e., abandoned/forgotten underground storage tanks (USTs)).
  • Expected County Growth: San Diego is one of the country’s most sought-after city/county thanks to its weather, diversity, and beautiful scenery. According to information obtained from, by 2040, the population of San Diego County is forecasted at 4.16 million people, a 26.60% increase from today’s population. Since there is no sight of a decrease in development, there will always be a need for environmental due diligence.
