Road Closure Mapping and Street Flooding Analysis
At a glance
The city's GIS division maps road closures during construction and flood events and shares them through a road closure website, the Tide Eye site and navigation apps. A street flooding analysis tool built on the closure data identifies what drives individual roads to flood.

- GIS Director Robert Hauck reported the road closure site and Tide Eye are the most-used GIS websites, and that closure feeds now go in real time to Waze, Google Maps, Apple Maps and TomTom, with Waze warnings for partly flooded roads such as Calhoun Street.
- Demonstrated a street flooding analysis tool (road closure, tide and rain history, Waze reports and a street forecast of roads at risk), and a Lockwood Drive study showing 443 flood events since 2015 at a 7.2 ft tide, with sea level rise scenarios. The tool is on the city GIS website and its data is still being vetted.
- Next king tide month is the end of November; a recap of the fall events is planned for a later meeting once NOAA tide data is released.
