That’s a 5am picture of the noise-making equipment across El Mirage from Rio Crossing. I’ve heard several people complain that this very loud noise is often occurring early in the morning.
If this noise is affecting you, call the Maricopa County Sheriff Department’s non-emergency line at (602) 876-1000. Yes, across El Mirage, it’s mostly Maricopa County property.
The storage business is in Avondale; everything else between Indian School and Camelback from El Mirage to the Agua Fria is Maricopa County.
FYI, Wigwam Creek to the west of Rio Crossing is also Maricopa County.
