What matters for project planning
None of these records governs remediation, but two of them are worth pulling anyway because they explain recurrence. Base flood elevation and flood zone tell you whether the property has taken water before, which changes what an assessment should look for -- contamination inside wall cavities from an earlier event rather than only what is visible now. The canal and stormwater infrastructure is the other: on a canal-platted lot the water table sits close to the surface and is managed rather than natural, so a structure can stay persistently damp for reasons that have nothing to do with the roof or the plumbing. Where correcting a moisture source means regrading or altering discharge near a seawall, the permit path and waterfront constraints should be confirmed first.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Check these specifics with the city and the provider you choose before any work starts — a citywide overview can't substitute for a parcel-level answer.
