Signs on public space
Seems like this is a constant problem. Political candidates' campaign signs are posted on public space.
Both King County and City of Seattle campaign guidelines specifically spell out that campaign signs are not to be posted on public spaces. These signs become a double problem, first when posted and second, when the campaigns never clean up, so we look at these illegal signs until they evaporate.
I am certain that our neighborhood is not unique with signs posted on green medians that are clearly public spaces.
