Gravois Mills is farther up the Gravois Arm than Laurie, in a quieter part of the west side. The work here is often a new dock on a lot that has never had one, or a used dock someone wants to bring in from another cove. Both are permit projects. Neither is a tow-and-tie.
Used docks
The structure can be bought and sold. The permit cannot follow it. Ameren’s sentence is short: a dock moved to a different property needs a new permit before installation, and the existing permit number stays with the property it left. Read used docks and relocation before you pay for a dock on a trailer. The destination still has to meet cove limits, setbacks, and flotation rules. A dock that was legal in a wide cove can be too long for a Gravois Mills cove. Compare it with the Gravois placement rules.
New docks
A first dock is the new dock path: scaled drawings, neighbor distances, a $550 fee, and no construction until Ameren issues the permit. If you want a lift the same year, include the boat length now. Adding it later can be a second modification.
Same arm, different town
Laurie and Gravois Mills share the arm and not the shoreline. A builder scheduling a barge cares which one. Pick Gravois Mills on the form only if that is the closer town, and still write the cove. If you are between the two, say so in the notes. The Laurie page covers the shallow-cove walkway question, which shows up on this stretch too.
