The city hopes to relieve flooding problems in the Mirage subdivision on the far West Side with some ditch and curb work planned for this fall.
Mirage residents have been subject to flooding that city engineers attribute to water and debris coming from a neighboring farm field during heavy rains.
Joliet Public Works Director James Trizna told the City Council last week that no permanent solution will be in place until the farm field is developed and more water detention is put in place.
For now, however, the city will attempt to ease flooding by regrading sections of a ditch on the west side of County Line Road and lowering a curb and sidewalk on the east side of the road to allow water to pass more easily during heavy rains.
“Whenever there’s a big rain, it will flood over County Line Road,” Trizna said Wednesday.
Lowering the curb and sidewalk is intended to limit the extent of the flooding, he said.
The council on Sept. 15 approved a $145,000 contract with P.T. Ferro Construction Co., the lowest of four bidders for the job, to do the work, which includes the extension of a fence used to trap debris coming off the farm field.
The engineer’s estimate for the job before going out to bid was $109,000.
The P.T. Ferro bid “is above the engineer’s estimate,” Public Works Administrator Greg Ruddy told the council’s Public Works Committee when it reviewed the bid. “But we feel it’s important work to get completed before next spring.”
Ruddy said the ditch and curb work is aimed at getting runoff water from the farm field into the drainage system faster.
Crop debris also is an issue because it clogs the drainage system. Grates, which had been clogged with debris, were removed from pipes leading into the detention pond earlier this year to open the flow of water.
City officials met with the home owners association board and with residents through a Zoom meeting in June to discuss the flooding and plans for relief after getting numerous complaints about flooding that occurred during heavy rains in mid-May.
