I called the board of health once because of trash blowing into our yard from the property across the street. I had tried to call the place, but no one answered, and there was no answering machine. The board of health was very helpful. I was impressed at their quick response.
City health department sent me notice and threatened fines if I didn't get it mowed within a certain time frame. Most of the neighbors had my number, but the one that didn't had called the health dept. No one called me.
I knocked on the doors of everyone, and apologized for what had happened, told them I fired the guy, and to let me know if the new one fell down on the job.
It was embarrassing, and of course they track the number of incidences and become less and less tolerant even if the recurrence is many years later.
