He said that work included changes to improve the water flow around Pigeon Creek, which feeds into the river, and also improvements to local storm sewers.
"Updating them, changing the design, protecting our sanitary sewer system from clear water - rainwater - leaking in to protect businesses as well," LaFond said of the improvements.
He added Thiensville only received about four inches of rain overnight, but that areas along the river and North of the village got hit harder.
"We're at the mercy of what flows downstream," LaFond said.
On Monday morning, neighbors at Thiensville's Village Park spotted a boat that was washed away from its dock sitting stuck in the middle of the river and surrounded by debris.
Debris from trees and yards, and even a nearby wooden dock that was washed away by the high waters, were churning in the Thiensville dam.
At the Village's Department of Public Works facility on Freistadt Rd., workers set up a pile of sand, and bags, which were complementary to village residents hoping to fortify their homes and businesses.
But LaFond noted many of the locals are used to the river periodically flooding and have their own sandbags already.
"A lot of the people that have lived here, or have done business here, for a long time are quite savvy," LaFond said.
