The CBRC position on offshore county lines.

The CBRC recognizes that there are many different methods to determine at-sea boundaries of a political unit such as a state or county. The Committee reviews records only at the state level. It makes no formal decisions regarding the county in which a particular bird at sea may have occurred, beyond listing the nearest point of land in published reports and in its database.
