“After that, the matter will most likely go before the Planning Commission,” said Reber. “We always encourage citizens or anyone installing something to first check with the city to make sure the applicable codes and regulations are followed. But ultimately, this will be up to the Planning Commission.”

Wolf, who recently sent a letter of concern to the city that was signed by several Randolph Street residents, said that she doesn’t want to infringe on Hullquist’s rights. But she worries about the stability of the tower.

“It’s a colossal radio antenna that could fall or have environmental impacts,” she said last week. “This is a historic district and it is terrible to look at.”

Stacey De Shazo, a preservationist with Napa County Landmarks, said she has spoken to city staff about the antenna, but is currently unaware of any codes that would ban such installations.

“We’re still researching the matter, but it would be a shame if people put these huge antennas up all over historic districts,” she said. “The city may have to try and legislate this type of thing.”
