What the map may miss
Heavy rain and sewer flooding
FEMA maps focus mainly on river and coastal flooding. They do not fully capture basement backups, overwhelmed street drains, or water entering during intense rainfall.
For renters
Your unit and building matter
Floor level, exits, elevators, power needs, landlord maintenance, and where you keep essential items can change your personal risk.

Put the result in context
Your FEMA zone is one piece of the picture.
A basement or ground-floor unit may be exposed even when the broader mapped zone is lower risk.
Elevators, power, medication, communication, and evacuation support can change what preparation is needed.

How it works
Three kinds of information, kept separate.
Official mapped hazard
We query FEMA's National Flood Hazard Layer at the searched point and report the zone returned.
Local limits and context
We explain what the federal map may miss, including sewer backups, intense rain, and building-specific conditions.
Your renter plan
You can add floor, exit, disability, power, medication, and animal information to personalize preparedness guidance.
Why this exists
Flood tools rarely start with renters.
Renters may not control drainage, building repairs, elevators, or emergency procedures, but they still face damaged belongings, displacement, missed work, and inaccessible exits. FloodRisk Philly turns a map result into practical questions and actions.
Works when the weather does not cooperate
Install the preparedness guide for offline access.
The app shell, planning questions, saved checklist, and official resource links can remain available after installation. A new address or FEMA lookup still requires an internet connection.
Official resources
Save these before you need them.
ReadyPhiladelphia alerts
Get official emergency and severe-weather notifications.
City flood resources
Preparedness, maps, recovery guidance, and local contacts.
Water emergencies
Information for neighborhood flooding, basement water, and water-main breaks.
Reported flood damages map
See reported Philadelphia flood damage from 2014–2024, including rainfall and drainage-related flooding beyond FEMA zones.
Method and transparency
What the app checks—and what it does not.
Address
Philadelphia's public address locator matches the entered street address and returns coordinates and ZIP code.
Mapped flood hazard
The app queries FEMA's National Flood Hazard Layer at that exact point and translates the returned zone into plain language.
Personal plan
The checklist is generated from answers about the unit, building access, disability, medical needs, and animals. It is guidance, not a formal risk score.
App version: 9
Important limitation
FloodRisk Philly provides educational information and renter preparedness guidance. It is not an insurance determination, engineering assessment, emergency warning, legal opinion, or guarantee that a property will or will not flood.
