How to Report Flooding & Why

New York City also has a webpage for reporting sewer backups. They can be reported by calling 311 or by filling in this online form.

The New York City 311 web site has several other pages to report/complain about water related issues.  If in doubt call 311.  Here are some key ones:

How to report flooding & why

The Red Hook NY Rising committee developed a questionnaire after Sandy to guide you in recording your specific observations. Report these to 311 because this is the data the city is looking at, and the DEP (Dept of Environmental Protection that handles potable water, sewage treatment and storm drains) is in many ways a “complaint driven agency.”
The data is public, everyone has access to it. It can be used to map and help diagnose the type, frequency and extent of issues and determine if there is a public sector issue (and fix) related to the flooding, e.g.: is your cellar flooding due to a cracked storm drain pipe? (a City issue) or is the drainpipe from your roof broken? Share photos and video of problem spots with dates and times.  

The Red Hook NY Rising committee drainage packet provides a framework for understanding flooding issues and provides some possible remedies.
