1. A dome decal RFID marker comprising:
a flexible polymer substrate having a lower planar surface suitable for attachment by an adhesive to a planar surface of a storm drain;
an electromagnetic radiation decoupling layer attached to an upper planar surface of the flexible polymer substrate;
an RFID tag attached to an upper surface of the electromagnetic radiation decoupling layer at a location of enhanced electromagnetic field when an electromagnetic field is directed downward toward the dome decal RFID marker; and
a polyurethane protective layer sealing the RFID tag and the electromagnetic radiation decoupling layer to the flexible polymer substrate through viscous flow of the polyurethane protective layer prior to hardening.
