Cell Tower Map & RF Exposure in Chico, CA
Carriers Operating in Chico
Chico Nationally
Chico's RF score of 19 places it in the top 10% nationally for cell tower exposure. For a city of 101,475 residents, this suggests an unusually dense wireless footprint.
5G in Chico
Chico has just 1 5G towers so far — a small fraction of the network. Most wireless coverage relies on 4G LTE and older technologies. As carriers like T-Mobile continue rolling out 5G, this will change, potentially shifting RF exposure patterns in the area.
What Chico's Tower Density Means for Residents
With 1.1/mi², Chico has sparse tower coverage. Though towers are spread out, EMF scores in Chico range from 2 to 87 — some pockets sit much closer to infrastructure than others. If you're in one of those pockets, your exposure could be well above the city average.
Chico's RF exposure is rated Low
Most residents experience relatively low RF from cell towers. This is a good baseline, though individual homes near tower clusters may still score higher.
What This Means for You
With only 3.7 towers per 10,000 residents, Chico has relatively thin wireless infrastructure. Most homes won't have towers immediately nearby — but those that do can see a real impact. Searching your address shows the full picture.
Power Lines & ELF Exposure in Chico, CA
How Power Lines Affect Chico Residents
Chico has 12 transmission lines and 7 substations within 5 miles of the city center. This includes 2 lines carrying 345 kV or more — the highest voltage class, which produces stronger ELF fields over a wider area. For homes near these corridors, distance is critical: ELF drops off sharply, but high-voltage lines have a larger impact zone than lower-voltage infrastructure.
Substations Near Chico
There are 7 substations in the area, where high-voltage power is stepped down for local distribution. Like transmission lines, their ELF fields drop off quickly with distance. If you can see a substation from your home, it's worth checking your address to see how it affects your score.
Chico's ELF exposure is rated Low
Most residents are far enough from high-voltage infrastructure that ELF isn't a major concern. Homes directly adjacent to power lines may still want to check their specific score.
RF vs ELF in Chico: Cell towers and power lines contribute roughly equally to Chico's EMF picture (RF: 19, ELF: 23). Both factors matter when choosing a location — check your address to see which sources are closest to your specific home.
What This Means for You
Chico has some high-voltage (345+ kV) infrastructure nearby, which creates stronger ELF fields over a wider area than lower-voltage lines. If you're close to one of these corridors, it can meaningfully impact your score — the map shows exactly where they run.
