Jack Tibbetts, a member of the Santa Rosa, Calif., city council, knew he had a problem. It was early 2018, and he'd started getting calls from constituents at opposite ends of the political spectrum. The common thread: cellular antennas going up next to their homes, causing concerns over property values and health. Cities and towns throughout Northern California are issuing ordinances that would exclude new 5G cell sites from residential areas, citing ... health concerns. Residents of Portland, Ore., and Whitefish, Mont., have also cited these beliefs while lobbying for restrictions. Legislators in four states including New Hampshire have proposed bills that would mandate further study of health effects or else urge Congress to do so, and Congressman Thomas Suozzi (D., N.Y.) wrote to the FCC echoing these concerns. For Mr. Tibbetts, it didn't matter whether or not these new "small cell" antennas ... going up in Santa Rosa were actually dangerous. What mattered was that his constituents didn't want these ungainly chunks of public infrastructure anywhere near them. Whatever the basis for residents' objections to new cell towers, Mr. Tibbetts - as well as countless mayors, governors and council members across the country - have little or no power under current rules to act on their constituents' wishes. Those who do take action are creating ordinances that put their cities at risk of being sued by the telecoms, as happened this month in Rochester, N.Y..
