Fixed Site Drone Operations Now Have a National Siting Math

One national envelope instead of dozens of local reviews

On July 28, 2026, the FAA completed a nationwide environmental finding for commercial drone delivery under Part 135. The Federal Register carried the notice of availability on July 30. Before this decision, each new market needed its own assessment, work the agency has said took six to eight months and sometimes a full year. One national analysis now covers the same ground. Taking the mitigation in the final assessment into account, the FAA concluded that the action it analysed would not cause significant environmental impacts. For any team planning a fixed base of operations near homes, the interesting part is the mitigation, because it is now the siting standard the agency will measure proposals against.

The numbers that travel with a site

The final assessment ties its finding to physical conditions. A unit capacity threshold of 1,150 average annual day deliveries from a hub. That ceiling comes from the noisiest en route sound exposure figure in today's delivery fleet, which the FAA puts at roughly 78 decibels. The agency's modelling holds that land near a hub running at that level would not see a 1.5 decibel rise inside an existing 65 decibel contour. At the full threshold, a hub has to keep at least 600 feet of separation from housing and other noise sensitive property. Quieter sites get scaled down distances from a lookup table, and the controlling figure at the nearest sensitive property is 59.7 decibels as a day night average. Flights cruise in a band from 150 to 375 feet, staying under a 400 foot ceiling, and covered aircraft can weigh as much as 110 pounds with the package aboard. Each application has to include noise measurements taken from the operator's own aircraft, so the numbers on paper can be checked against whatever is actually flying. Two further items matter near protected sites. Eagle nests get an avoidance bubble of 1,000 feet, and coastal routes must clear potential manatee habitat by 350 feet between June and October. Consultation with the U.S. Fish and Wildlife Service and state historic preservation offices is still handled case by case until programme agreements with those agencies are in place.

What a finding does not give you

This is a process document, not a permission slip. It grants no operating authority. Operators still need a Part 135 certificate and an operations specification amendment for every operating area, and a proposal outside the national envelope drops into a narrower supplemental review. The decision also carries a status note on the missing BVLOS rule: delivery work stays a Part 135 activity until Part 108 is final, and the FAA expects Part 108 delivery flights to start one or two years after that rule issues.

The objection, and the clock

In January, 17 state attorneys general plus Harris County in Texas asked the FAA to prepare a full programme level impact statement, arguing that a national analysis built without site specific data could not support a finding of no impact. The FAA kept the draft's core numbers. One thing did change. The draft had asked operators for hub setbacks; the signed text makes them mandatory, and it ties the no impact finding to them. Because the decision is a final order under 49 U.S.C. 46110, a party with a substantial interest can petition a federal appeals court. The 60 day clock for that runs out on September 26, 2026. If someone files, the operators holding measured noise data and documented siting are the ones best placed to keep working while the question is argued.

The takeaway

If you are planning a base of operations, whether a dock, a nest or a yard with recurring launches near residential property, design against this envelope before you sign a lease. Measure your aircraft's noise once and keep the measurement in the siting file. Keep the setback arithmetic with the permit package. Treat local engagement as a parallel process rather than damage control after a complaint, because the FAA has been clear that siting and land use approvals are the operator's job. The numbers are in the public record, and planners, neighbours and lawyers can all read them.
