Ridgefield officials are reminding residents about town ordinances requiring them to clear snow and treat ice on sidewalks in front of homes and businesses.  Officials say this will help keep Ridgefield safe for all walkers and runners.  Anyone who fails to comply with the ordinance could be required to pay a penalty of up to $100 each hour after the required removal time that snow, ice or sleet is not removed.  The amount of the penalty will be added to the amount of the cost of removal and will be a part of a lien.
