My kids LOVE to "go feed the ducks"! Multiple generations of local residents have enjoyed the same. I will not criticize township officials involved in this decision as it serves no real benefit. I also (personally) understand that many times elected officials are forced to make unpopular decisions, for reasons that some do not understand. However I surely hope that all other options are being (and will be) explored. If bank erosion is truly the concern...
Have we explored the option of using another material on top of the dirt to prevent this?
Possibly a type of stone that you see being utilized in similar applications in other places.
It is also important for citizens to do their part in taking responsibility for themselves and the foods you use to feed the geese and ducks.
