I'd been thinking about this lately, and was thinking of what advice I'd give to a beekeeper who also encounters this problem. Last year, we got an official letter telling us to limit the number of hives and the height of the hives. Of course, I got all up in arms because we had asked the city 3 years hence about city's bee ordinances which we never got a reply to. Turns out they only sent a letter because someone complained, and they had no ordinance, but felt like they had better write one up. We talked to these people who were at first defensive, but when we really listened, they reluctantly signed off permission. We bring them honey and greet them whenever we see them now. We also talked to the city in an very calm manner, and they admitted their omission and we offered to be on call if they ever had any questions. We also got our beekeeping teaching involved with the city to help them write their regulations. I realize our situation turned out well, but if you think there's something else that might be helpful, I'd love to hear your thoughts. Thanks!
