St. Peters to ask for Dardenne Creek flood assistance

East-bound lanes of Interstate 70 closed due to Dardenne Creek flooding in late December.

St. Peters officials plan to ask state and federal officials to find a way to prevent Dardenne Creek flood waters from covering Interstate 70.

The city’s Board of Aldermen is expected to pass a resolution at their Feb. 11 meeting asking the Missouri Department of Transportation and U.S. Army Corps of Engineers to address the problem.  The resolution is expected to be sent to the agencies, the state’s congressional delegation, and the St. Charles County state legislative delegation.

Alderman Rocky Reitmeyer [Ward 1], who sponsored the resolution, told aldermen at a Jan. 21 work session that he is trying to see if state and federal officials can “engineer some ideas” to prevent future flooding.

Flood waters from 8 to 12 inches of rain starting on Dec. 26 caused creeks and rivers throughout the St. Louis area to surge out of their banks.  Rising water on Dardenne Creek, which flows through much of the central part of the county, through Cottleville, Dardenne Prairie and St. Peters, covered roads and caused damage to some homes

Briefly those flood water inundated particularly the east-bound lanes of I-70 at a bridge crossing Dardenne Creek at the I-70-Hwy. 79 interchange. “What it did was shut down commerce,” Reitmeyer said.  Reitmeyer said he knows that flooding along the Meramec River in south St. Louis County was worse but I-70 is a major transportation thoroughfare.

Russ Batzel, the city’s manager of transportation and development services, told aldermen that the bridge appears on recently adopted Federal Emergency Management Agency flood plain maps as part of the 100-year flood plain and that could be added to the resolution.  The resolution should note that the interchange area may flood in the future, he said.

The board agreed to consider adopting the resolution at their Feb. 11 meeting. Batzel said any solution may require a study of not only the immediate area at the interchange but other areas in the creek’s watershed.

Flooding from nearby Dardenne Creek prompted sewers connected to storm water lines to back up into basements in some adjacent homes, severely damaged at least one home in Cottleville, and limited access in and out of several subdivisions. The flooding also prompted the closing of a number of city parks but major damage may be limited.
