At G2, we’re always looking for ways to improve the quality, speed, and accuracy of our environmental services. One of the most effective tools we’ve added to our toolkit is drone technology, especially for Phase I Environmental Site Assessments (ESAs) on large, complex properties throughout the nation.
With a team of licensed pilots on our team and a fleet of drones, we now regularly incorporate drones into our environmental assessment processes. This is particularly valuable when assessing large-scale properties—100 acres or more—or when dealing with difficult-to-access areas like wetlands, wooded tracts, or uneven terrain. These features are common in rural and undeveloped parcels often involved in commercial or industrial real estate transactions.
By flying drones up to 400-feet aboveground from a central location on the site, our team can efficiently capture comprehensive imagery of the entire property. This provides a much clearer, up-to-date view of the land than traditional ground photography or even satellite images available online. It also supports our environmental professionals during site reconnaissance and photolog documentation, resulting in more thorough and visually supported reports.
We primarily use the DJI Phantom 4, which is highly maneuverable and well-suited for most properties. For very large or complex sites, we deploy the DJI Inspire 2, a powerful drone that captures high-resolution images across wide landscapes. When assessing sites that exceed 1,000-acres, such as for large commercial developments or infrastructure projects, we may use both drones together to ensure full coverage in a short amount of time.
Drone-assisted ESAs offer significant time and cost savings for clients purchasing or redeveloping large parcels. For example, our team recently completed a Phase I ESA on an approximately 500-acre site in Michigan in just six hours, a job that would normally take two full days with traditional field methods. Faster site assessments help accelerate the due diligence process, keep transactions on schedule, and reduce overall project costs.
As the demand for large-scale property development continues to grow across the nation, integrating drone technology into environmental due diligence allows us to deliver better data, faster. For clients needing a Phase I ESA on a large property, our drone-equipped team can provide a more complete understanding of the land before a single shovel hits the ground.
