The Ridgefield Planning and Zoning Commission is set to consider a request to end the ban on drive-thru food service.  Attorney Bob Jewell wrote in a letter to the commission that the argument leading to the ban was made in the 1970s when littering was rampant.  He claims some people do still litter, but they are the exception and not the rule.  The request was made as a "pre-submission concept discussion" for 896 Ethan Allen Highway.  The Route 7 property is just south of the intersection with Route 35. Jewell proposed in his letter that drive-thrus be allowed only in zones where restaurants are already permitted. The Planning and Zoning Commission is set to hold a virtual meeting on Tuesday night.
