FEMA uses a 1 percent annual chance flood as a base reference in its flood-map framework. That is a probability definition, not a prediction of what will happen at one manufactured home community.
Build a source record
Store the map link, address or parcel reference, map date, reviewer, and next review date. A virtual assistant can collect the record and flag changes. The owner should ask the qualified local, insurance, engineering, or emergency-management professional to interpret it.
Do not label a home safe or unsafe from a national statistic. Local elevation, drainage, permits, infrastructure, insurance terms, and current maps can change the answer. Keep the FEMA reference beside, not in place of, local evidence.
