You may send them to the clerk. That will be fine.
In your report you provide a number of solutions to reduce railway noise at the source. I am pleased to see that you are aware of that. I know that there is a quieter locomotive that can be used in rail yards. I think it is called the Green Goat. These special locomotives operate more quietly when accelerating or decelerating. These solutions, if they are effective, will probably be introduced by the Canadian Transportation Agency.
However, are the municipality representatives aware of the fact that zoning can represent a source of conflict between the urban planners and the railways? When you allow a developer to build housing next to a railway track, you must not be surprised when the homeowners begin to complain.
With that mind, have you made any changes to your zoning bylaws, in order to deal with this problem at the source?
