Frozen storm sewers, overnight rain and higher temperatures are to blame for flooded streets in Janesville on Monday, said Kamron Nash, operations superintendent for the Janesville Public Works Department.
Frozen water in storm sewers, commonly seen this time of year, blocks water from draining off roads, Nash said.
A quick onset of mild weather was enough to melt snow but not melt ice in the storm sewers, Nash said.
The public works department received a number of calls Monday morning about standing water, Nash said.
Areas of concern for flooding include:
- Ruger Avenue and Greendale Drive near Blackhawk Creek
- Randall Avenue near Sherman Avenue
- Mount Zion Avenue and Sumac Drive near the Interstate 90/39 overpass
Standing water normally recedes a couple of hours after rain stops, Nash said. City crews will treat frozen storm sewers with calcium chloride to melt ice if needed.
Motorists should never drive through standing water, Nash said.
In a news release issued Monday morning, the city encouraged property owners to clear storm sewer catch basins. The city has about 7,600 catch basins across 332 miles of paved streets, according to the release.
On Monday evening, the city announced it was closing Ruger Avenue near Greendale Drive until the flooding recedes.
City crews try to keep catch basins clear, but property owners are encouraged to do their part to prevent localized flooding by clearing debris from catch basins in front of their properties or in their neighborhoods, according to the release.
Anyone who sees standing water in the city can report it to the public works department at 608-755-3110.
