Evacuation Zones Are A Storm Tool, Not A Basement Guarantee
On Staten Island, the coastal storm evacuation map is one official check, but basement flooding can still depend on rain, drainage, and property conditions.

Staten Island storm planning gets clearer when you separate evacuation zones from basement trouble. NYC Emergency Management’s Know Your Zone map is the official coastal-storm evacuation-zone lookup, and the coastal-storm guidance explains how the city prepares for hurricanes and storm surge. That does not mean every basement outside an evacuation zone is dry, or that every wet basement means a home is in the most severe storm-surge area.
Heavy rain, blocked drainage, sewer backups, grading, old foundation work, and catch basins can all matter too. Use the evacuation map for city storm instructions, then inspect property-level clues separately: water marks, sump pumps, backflow valves, yard slope, and past repair records.
The two checks can live in the same folder, but they answer different questions. One is about city storm guidance. The other is about the way a house, block, or basement handles water.
A Staten Island block can have one house with a dry basement and another with repeat water trouble. Keep the exact address in front of you, check the map, and ask the narrow question. It keeps a serious topic useful instead of scary.
