After a tumultuous visit from an uninvited guest Sunday, Westport town and emergency-services officials assessed the unwelcome impact from Tropical Storm Irene.

"There was so much water flowing down the street, it was like a river," said Main Street resident Brandon Stavola. "I felt like I was in Venice."

The Saugatuck River overflowed Sunday morning into Parker-Harding Plaza and Main Street, while authorities shut down power in the town center to prevent electrical fires.

Bob LeRose, owner of the Main Street restaurant Bobby Q's, reported that his business emerged unscathed. He said, however, that the downtown economy might not return to full strength for another week.

"In the aftermath of Tropical Storm Irene, we are grateful that there was no loss of life or serious injuries," First Selectman Gordon Joseloff said in a statement Sunday. "We are now engaged in what is likely to be a difficult and prolonged recovery process."

About 70 residents stayed Saturday night at the town's emergency shelter at Long Lots Elementary School, but all guests had left by 3 p.m. Sunday, Human Services Senior Program Coordinator Susanne Lebrija told the Westport News.

Fire Chief Andrew Kingsbury said the Fire Department responded to a small electrical fire Sunday morning in the Compo Beach area, but added that the storm's impact was mostly limited to flooding and power outages.

"The flooding was what we expected," he said. "I think we were fortunate that the storm died a little before it got to us. But we really geared up and we were very organized."

By mid-afternoon, the river waters had receded from downtown and fire crews arrived to begin pumping out flooded basements on Main Street.

Kingsbury declined to estimate when power would be restored to downtown Westport and the rest of the town.
