Buchanan County officials are monitoring the potential this week for high water from flash floods to cause travel problems for motorists on East Mitchell Road, where a gate can be closed to prevent vehicles from proceeding eastward out of the St. Joseph city limits in the vicinity of the One Hundred and Two and Platte rivers.

Continued bouts of heavy rain Tuesday are causing city and county crews to stay on guard for the potential for roads to be inundated by water.

Buchanan County Emergency Management Director Bill Brinton told News-Press Now he had no new word as of mid-afternoon on roads being closed due to high water. Brinton said he had personally checked the levels of both the One Hundred and Two and Platte rivers just east of St. Joseph.

“Rivers aren’t out yet,” said Brinton.

Although the county had been teetering on the edge of inclusion in a flash flood watch earlier in the day, the National Weather Service in Pleasant Hill later revised the map to include the county.

Many of the county’s most flood-prone roads are located in the southern and eastern portions, with the Eastern District consisting of about 15 of the most susceptible roads.

The county has a plan in place for its roadways in case of heavy rains. For example, ditches along East Mitchell Road have been designed to alleviate high water flowing out of the Platte.

“We’ll be monitoring the Platte River,” said Brinton. “Our crews go out and look at the river.”

Otherwise, for the county, all roads that were closed due to the Missouri River flooding in March have since reopened, with no reports of any standing water.

Brinton said no appreciable changes are anticipated in the Missouri River levels. The Platte River at Agency, Missouri, measured at 10.82 feet and was expected to rise to 19 feet later this week. Minor flooding occurs at 20 feet.

City of St. Joseph spokeswoman Mary Robertson said street crews automatically monitor areas that flood. She cited the 3200 block of Faraon Street as just one such example.

Motorists are notified via the Nixle alert system of the city’s decision to close streets to traffic due to high water, said Robertson.

The National Weather Service says low-water crossings are at the greatest risk for flash flooding.
