Description

On Wednesday, [the] low-lying reaches of Rocheport gained extra flood protection. A crew of about 15 Boone County workers laid a row of concrete Jersey barriers along the Katy Trail.

Crews expect to have 1,700 feet of the concrete slabs in place and lined with plastic by Friday evening. The barriers, each standing 3 feet high and weighing 2 1/4 tons, act as a levee that withstands river levels up to 34 feet. The properties directly behind the trail would flood at 31 feet without the barrier.

The Missouri River was 22.9 feet on the Boonville gauge Friday and is forecast to dip below its 21-foot flood stage Monday for the first time in weeks. Zondca said he has aspirations to elevate the lowest portion of the trail in Rocheport.
