Document Description
Approval of a Major Modification to the existing Piazza del Dotto Winery to increase production, number of employees, and number of visitors. The project would add additional events to the existing marketing plan, permit visitation and on-premises consumption in additional areas on site, and allow outdoor speakers for background music. Physical changes on site include construction of an approximately 10,500 s.f. winery building with a 700 s.f. lounge building, increase the existing cave from 16,000 s.f. to 32,500 s.f., cabanas on the existing hospitality building patio, and additional parking spaces. The winery would continue the use of the existing hold and haul with analysis of a process wastewater treatment system to be installed at a later date.
