RICHMOND â The long-running effort to limit sound from musical performances outdoors and in a barn at Balderdash Cellars winery and farm appears to be nearing a written agreement between the town and owners Christian and Donna Hanson. The proposed new conditions, which come as the couple seeks a special permit that would combine the existing farm function bylaw with events at a renovated barn, are intended to allay noise concerns raised by some nearby residents. Under the terms of the compromise, the town would allow a wider window of time for events than the town initially sought, but the owners would agree to a number of steps designed to limit the impact of noise on neighbors.
