Cell Tower Map & RF Exposure in Tacoma, WA
Carriers Operating in Tacoma
Tacoma Nationally
Tacoma's RF score of 58 puts it in the bottom quarter nationally — lower cell tower exposure than roughly 75% of US cities we track.
5G in Tacoma
Tacoma has just 13 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 Tacoma's Tower Density Means for Residents
With 16.8/mi², Tacoma has dense tower coverage. Many residents have at least one tower within a few blocks, but EMF scores still range widely — from 2 to 100. Even in a dense tower environment, your exact location relative to tower clusters makes a significant difference.
Tacoma's RF exposure is rated Elevated
Many residents have elevated RF exposure from nearby towers. If you're concerned, search your address to see how your specific location compares and which towers are closest.
What This Means for You
For a city of 228,202 people, Tacoma has a high concentration of wireless infrastructure — about 36.5 towers per 10,000 residents. Your personal exposure depends on how close towers are to your home, especially to bedrooms. Search your address to see exactly which towers affect you.
Power Lines & ELF Exposure in Tacoma, WA
How Power Lines Affect Tacoma Residents
Tacoma has 98 transmission lines and 71 substations within 5 miles of the city center. This includes 1 line 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 Tacoma
With 71 substations in the area, Tacoma has significant power distribution infrastructure. These are the points where high-voltage power is stepped down for local use. Each one creates a localized ELF field — if you live within a few hundred meters of one, it likely contributes to your score. The map shows exactly where they are.
Tacoma's ELF exposure is rated Moderate
Some parts of the city are near high-voltage transmission corridors (345+ kV), which have a wider ELF impact zone. If you live near visible power lines, checking your address will show how much they contribute to your personal EMF score.
RF vs ELF in Tacoma: Cell towers have a somewhat bigger impact than power lines in Tacoma (RF: 58, ELF: 45), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
Tacoma 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.
How Tacoma Compares: Cell Towers & EMF Scores
Tacoma has a notably elevated electromagnetic field (EMF) exposure level of 58, ranking at the top of Washington state and significantly above both the state average of 49 and national median of 45. While cities like Spokane and Bellevue have lower EMF readings, Tacoma residents experience higher potential electromagnetic radiation levels that could be a consideration for those sensitive to such environmental factors.
