Santa Clarita, California · A resident-led project

SCV Dead Zone Map

Santa Clarita keeps growing, but cell coverage hasn’t kept up. Whole neighborhoods have streets — and rooms — where calls drop daily and data won’t load, while the carriers’ official maps claim full coverage.

So residents are pinning the dead zones themselves: your neighborhood or nearest cross streets (never your home address), your carrier, and the problem — no signal, dropped calls, or data that won’t load. Every pin becomes part of one map the carriers can’t wave off.

Report a dead zone Sign the petition

This is an independent resident effort. It is not affiliated with any carrier, and it is not affiliated with the City of Santa Clarita or LA County.

Nobody here can promise new towers or any specific outcome. Here is the promise we can make: every report is compiled and presented to AT&T, Verizon, T-Mobile, the City of Santa Clarita, and LA County — and the tallies are reported back here as they grow.

One valley, mapped by the people who live in it

Seven communities, one shared problem. The pins below mark the neighborhoods being mapped — your report is what turns a marker into evidence.

Two ways to be counted

Do one, do both — each takes about a minute, and neither asks for your home address.

Report a dead zone

Pin the spot where your phone fails. Three things, that’s all:

  • Your neighborhood or nearest cross streets — never your exact home address
  • Your carrier
  • The problem: no signal, dropped calls, or unusable data
Report a dead zone Takes about a minute.

Sign the petition

Add your name to the ask that goes out with the map:

  • Asks AT&T, Verizon, and T-Mobile to remediate the documented dead zones in Santa Clarita
  • Asks the City of Santa Clarita and LA County (for unincorporated pockets like Stevenson Ranch) to prioritize timely approval of the wireless-infrastructure applications that would close these gaps
Sign the petition Takes about a minute.

Make it count

Your report builds the local map. These two steps put the same dead zone into the official record — the one carriers and regulators actually have to answer to.

Challenge the coverage map with the FCC Speed Test app

Download the FCC’s free Speed Test app. Stand in the dead zone — outdoors, or in a moving vehicle — and run a test in challenge mode.

That test officially disputes the coverage your carrier reports to the FCC. The FCC aggregates challenge tests like yours to correct the National Broadband Map — the map carriers and regulators rely on when they claim Santa Clarita is covered.

File an FCC informal complaint

File a short complaint at consumercomplaints.fcc.gov. The FCC serves it on your carrier, and your carrier is then required to respond to you in writing within 30 days.

Coverage complaints filed this way land on the carrier’s regulatory team — not a call center. It’s the same dead zone, heard by the people who can actually move it.

The more of the valley that’s on the map, the harder it is to wave off. Share this page with your street, your group chat, or your HOA page — and get your pin in first.
