Andy sits on the Florida Greenbook Advisory Committee, so he was able to share updates to the 2020 Greenbook Drainage chapter, which identifies the uniform minimum standards for design, construction, and maintenance for all public roads that are not part of the State Highway System, or FDOT controlled roads.
