The first file on the lower archive flood map began with the flood map, its copy register and later margin notes. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year fifth, high summer window 1 file records 46 map marks with a dated source note; the previous window records 49. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that a blue channel line appears on one copy but not the filed public sheet. It narrowed the discussion from a general claim to a question about how the rule works at the site.
The line is visible on the surviving copy. The archive has not found a matching field survey or a named hand. The shared record is larger than it was at the start, although the parties still assign it different weight.
Asecond office checks the count and records any difference in method. The Year fifth, high summer window 1 file remains open for its scheduled decision. The archive will publish the two copies with their later marks dated separately.
