At the map room under Ferry House, Ava Korr puts the flood map, its copy register and later margin notes beside a blue channel line appears on one copy but not the filed public sheet. The detail is easy to miss in a summary, but it determines whether a posted rule describes the place people actually use.
Ava Korr is the municipal map archivist. On this river rise visit, the work begins with a dated entry and ends with a second check from someone who did not make the first one.
The the flood map, its copy register and later margin notes lists 24 map marks with a dated source note; the previous window lists 28. Ada Merrow checked both against ward records and interviews with people who use the service. The number is one part of a larger handoff between the office, the people who use the service and the staff expected to maintain it.
The line is visible on the surviving copy. The archive has not found a matching field survey or a named hand. Residents and workers have asked the clerk to keep their accounts beside the source count rather than turn them into a single average.
The clerk closes the docket and gives the next review a fresh scope. The board closed this docket after it retained the existing rule and published the reason for doing so. The next window starts with a fresh record.
