A decision on the lower archive flood map should be judged at the map room under Ferry House, where the rule changes an ordinary route, shift or service. Follow a public decision from the signed page to the household that has to live with it. The current file is the Year fourth, high summer window 2 review, not a permanent settlement of every future case.

The the flood map, its copy register and later margin notes lists 91 map marks with a dated source note; the previous window lists 96. Marek Stone checked both against posted terms set beside signed receipts and final invoices. The difference matters because whether the line records a lost spill channel or a later copyist’s change.

The line is visible on the surviving copy. The archive has not found a matching field survey or a named hand. Those objections deserve a clear answer. They are not a reason to keep an uncheckable rule simply because its wording is familiar.

A useful decision names who will do the work, which count will change and when the result comes back to the public table. In this case, a blue channel line appears on one copy but not the filed public sheet.

The responsible office has begun the follow-up set by the board, which retained the existing rule and published the reason for doing so.
