Heavy rain combined with intense, localized squalls flooded several intersections over the weekend, but the worst is over, Tacoma streets and environmental services managers said Monday morning.
No Tacoma street closures were reported Monday morning, but the weekend was a different story.
Tacoma public works and environmental crews worked around the clock through the weekend to monitor the citys stormwater system and close roads due to flooding or downed trees. The flooding was so intense in some places that manhole covers were lifted by the force of the water and geysers shot several feet into the air.
Monday morning crews were flagging traffic near a minor slide on Marine View Drive, said Rae Bailey, manager of the street operations division for Tacomas public works department.
Part of the problem is a pump station that normally would help relieve the pressure on the citys stormwater system remains under construction, said Mike Slevin, head of Tacomas Environmental Services Department. The work on that pump station is supposed to be done on Oct. 8, before the city thought fall storms would hit the area, Slevin said.
The system is very complicated, Slevin said Monday morning.
Areas that flooded include underneath the bridge at Pacific Avenue and South Tacoma Avenue and along the newly constructed Stadium Way.
The systems were designed to handle a 25-year intensity storm, Slevin said. He estimated that rain squalls on Saturday around noon were a 100-year intensity. A 100-year intensity storm has a 1 in 100 chance of happening in any given year.
The heavy rain is gone for now, Slevin said.
We will get more sprinkles and stuff, but right now the squalls are done, he said.
