 3.) Vineyard Development and Land Development

 Consultation Services:


Formerly known as Parks Vineyard and Trellising Systems (PVTS), after ten (10) years of custom vineyard installations in difficult terrain, we  discontinued the Vineyard Development and Agricultural Construction division of the business. Drawing upon those ten (10) years of experience, PVTS continues to collaborate with local land surveyors, engineering firms, vineyard managers, soil scientists and crop consultants on various development projects. PVTS still specializes in providing GIS project mapping services to production and custom vineyard development projects of all sizes.   


Since 2003, by design, our vineyard development services are restricted to project management, GIS analysis for project management, and independent development consultation.


NOTE: We no longer provide direct agricultural construction or land development services. PVTS does not resell vineyard products or materials.
