FloodRoute

because cars can't swim.

FloodRoute shows which roads may flood during high tides — before you drive into trouble.Regions covered:Boston, MA
Marin County, CA
Miami, FL
New York City, NY
Tampa, FL
Using NOAA tide data, road elevation mapping, topographical data, FEMA floodzone data, and reconciling all hard data with a layer of historical news reports, FloodRoute highlights flood-prone streets so you can plan safer routes in coastal communities.Inspired by Nextdoor neighbors in my home of Marin County, California, what started as a simple idea became a full-fledged app when I racked up nearly 200 requests to build the app within 24 hours of sharing my idea.So here it is at last... my first ever iOS app. 🎉
