Agriculture & Cannabis


The staff at HELIX are environmental compliance experts with specialized knowledge in the ever-evolving regulations impacting cannabis cultivation, vineyard management, and other agricultural operations.

Cannabis Environmental Compliance

Since 2016, HELIX has helped local agencies, cannabis cultivators, processors, and dispensaries throughout California bring cannabis operations into compliance with state and local regulations. HELIX provides a wide range of cannabis environmental compliance services including development of site management plans, watershed protection plans, biological and cultural resources reports, site restoration plans, County and State permit applications, lake and streambed alteration agreements, filings with the Water Boards, and agency consultation.
