Monday, March 13, 2023; M.M.C.A. Staff Writer – We are currently watching Senate Bill 638, which alters the definition of “aerial survey” for purposes of certain provisions of law relating to submerged aquatic vegetation protection zones to mean an aerial survey compiled by an entity approved by the Department of Natural Resources, rather than the annual survey compiles by the Virginia Institution of Marine Sciences for the annual Bay-wide SAV Mapping Program; and requiring the Department to update the delineations of SAV zones annually.
