Amazon's nascent drone delivery program is facing pushback in a Texas city where residents have been complaining of constant noise and raising concerns about safety and privacy.

Amazon Prime Air began operating in Richardson, a suburb of Dallas, late last year. Almost immediately after, the company's 80-pound drones began taking off and flying low over homes, locals started to complain, NBC DFW reports.

In February, one of the drones crashed into an apartment building. No one was injured, though the drone was left smoking on the ground.

A company spokesperson later explained to city council members that there was 'some type of interference' with the drone's GPS next to the apartment building 'of that size.'

The spokesperson then said the company 'removed all buildings of similar height and size from our delivery portfolio.'

But now residents say they regularly see the drones pass over their homes and even a nearby school as they make their way to their drop off locations from their takeoff facility on Research Drive.

They have even dubbed the constant overhead traffic a 'drone highway.'

'They've taken away our peace in our neighborhood and our neighborhood streets,' said Kristi Graham, who claimed to see the drones pass over her house every three to five minutes.

They are also noisy as they pass overhead, residents said.

'I can hear them in my home when I'm inside with the TV on,' said Angie Rogers. 'I can still hear them.' 

But one of the larger concerns is how low the drones appear to be flying.

'Those drones are barely at 100 feet over our homes,' Graham told the news station. 

'We've had drone operators come out and demonstrate, and it is way too low.'

In March, Richardson's City Manager said officials were encouraging Amazon to increase their base flying altitude to reduce neighbors' concerns. 

According to a Draft Environmental Assessment compiled by the Federal Aviation Administration, the maximum cruising altitude for these drones is 400 feet above ground level.

'Flight operations would take place mostly in an urban or suburban environment, within airspace and typically remain well above the tree line while en route to and from a hub,' the assessment reads.

It also notes that drone delivery operators may not fly over 'open-air assemblies of people, schools during times of operation..., moving vehicles... and roadways or highways.'

But residents said their concerns about the drones have not been addressed - and have even claimed there was not enough communication about the program before the drones started launching.

Several residents went as far as to claim only one homeowners' association was notified before the city council approved the measure.

'We were unaware of it completely until the drones started flying like six months ago,' Gary Martinie claimed.

Residents then started to complain about the program back in January, sharing their concerns with the city, the FAA, and Amazon.

Still, they say, they've seen little change.

'We've complained to the city, we've complained to the FAA numerous times with really no results,' said Martinie. 'Some promises, but no results.'

In an effort to bring renewed attention to the issue, residents from at least four different neighborhoods in the city held a protest on Saturday, once again demanding city officials and Amazon take action.

'I just wish they would relocate this drone port to a different area,' said Nancy Crowe. 'We would like them to go away and stop flying over our homes, our backyards, destroying our peace in our neighborhood.'

A spokesperson for Amazon, however, told NBC DFW that customer feedback on Prime Air deliveries has been overwhelmingly positive.

In an emailed statement, the spokesperson also emphasized that the company made efforts to engage with the local community before launch.

'Our team engaged extensively with Richardson residents, city leaders and neighborhood associations before launching drone delivery in this area,' the spokesperson said. 

'We also increased flight altitudes and adjusted flight paths to reduce impact on residential areas.'

The spokesperson added that the company respects residents' rights to peacefully protest and welcomes company feedback.

'We will continue working with community members and city officials to address their questions and concerns,' the spokesperson said. 

The Daily Mail has also reached out to Amazon, the FAA and city officials for comment.
