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 Federal Way
With 33 substations in the area, Federal Way 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.
Federal Way'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 Federal Way: Cell towers have a somewhat bigger impact than power lines in Federal Way (RF: 48, ELF: 38), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
Federal Way 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.
