A drainage project at St. Ambrose University, Davenport, that has traffic down to two lanes on busy West Locust Street is expected to begin in earnest later this week.
On Wednesday or Thursday, workers will begin laying of some of the 9,000 feet of 4-foot pipe that will be buried in the ground under where the parking lot for Cosgrave Hall used to be, said Jim Hannon, director of the school’s physical plant.
The pipe, which will collect 1.1 million gallons of rainwater, aims to alleviating chronic flooding on West Locust Street and parts of campus during heavy rainstorms, Hannon said. The pipes will slowly release the water into the ground and the city’s storm sewer system.
The pipe work is expected to take about three weeks, at which time the parking lot will be reconstructed. Reconstruction will include storm drains and 470 square yards of permeable paving that will convey stormwater from the lot to the pipes below, said Paul Loete, of MSA Professional Services, Davenport, which designed the project.
New, larger storm drains also are being installed on Locust Street, he said.
Of the $1.85 million total cost of the drainage project, the city’s share is $642,000 and St. Ambrose’s is $814,000. Funding also includes a $400,000 grant from the Iowa Department of Agriculture and Land Stewardship.
