A public hearing is being held in Ridgefield tonight on a petition allowing mobile food vendors to park for extended periods at breweries and wineries.  Food trucks can currently only park for 15 minutes at one spot.  Nod Hill Brewery circulated a petition to allow mobile food vendors at their Route 7 location.   According to the town charter, any petition signed by 2-percent or more of registered voters must be considered in a public hearing and town meeting within 45 days.   The exception to the current ordinance would require the food truck to be on the same property as the brewery or winery and that it operate in the same “general hours” as the business.  The public hearing and town meeting is set for 7:30pm.
