Packet details and supporting record
Document context, not a separate decisionThe packet’s March 6 Civiltech analysis puts numbers behind the map difference: excluding Lake Michigan, it counts 567 parcels in the FEMA floodplain and 1,226 in the expanded local floodplain, a difference of 659. Those are mapped-parcel counts, not a prediction of which properties will flood; overlapping condominium parcels were counted as a single parcel.
