Early Flood Warning

Program

We are working on a pilot program that focuses on collecting data and using technology to make flooding predictions in advance of a storm.

Phases

Phase 1 (Complete)
Crabtree Creek Watershed to a point downstream at US 1

Phase 2 (Underway until Sept. 2021)
The rest of the Crabtree Creek Watershed plus Walnut Creek Watershed

This is for areas in Raleigh only. We'll also look at making improvements to the system (i.e. adding more gauges and routine maintenance).

Current Data Collection Times

A US Geological Survey stream gauge near Walnut Creek — A stream gauge on S. State Street.

We have partnered with US Geological Survey to collect stream gauge data every five and 15 minutes (instead of every hour) at specific locations. We'll see more response times and alerts like this as we launch the program across the city.

Note: We don't receive data right away. There is a brief period from when data is collected to when it's available on our dashboard.
