The site work on the project is now nearly complete with all concrete, pavement, fencing, and restoration installed. The only remaining item on the project is the fabrication of the permanent pump which is expecting to be installed in the next 2-3 weeks. No other work is anticipated before then, and the basin is now functional and able to take storm water if needed during any large rain events.

Southwest Elmhurst Stormwater Mitigation Project-Phase II - Update 10.09.18

The rough excavation, stone rip-rap installation, topsoil installation, storm sewer installation, and force main installation was completed last week. The new stormwater pumps that will drain the basin are currently being fabricated and concrete restoration is anticipated for this week. Until the pumps are installed the basin will temporarily have ground water in the bottom. The Jackson Street pavement will be resurfaced at the same time as the Phase I project directly to the east to create a seamless pavement surface. Finally, the new 6’ black vinyl-coated permanent fence will be replacing the temporary fence as one of the last items of the project.

The detention basin excavation is now complete and a majority of the stone along the bottom has been installed to prevent erosion. The contractor has begun installing the sewers from the street to the basin and will also be installing the force main which will drain the basin after rain events. The final limit of the stone bottom was modified based on field conditions and a new rendering of the basin is shown below. With the new brick paver parking lot at Christ United Methodist Church now complete and striped the parking lot is now available for use by the church.  Work is expected to heavily impact Jackson Street traffic for approximately 2-3 more weeks while the underground work is completed and the road is restored. After that point, the remaining work will include restoration of the grass areas and fence installation. The contractor is continuing to coordinate with Jackson Elementary School during drop-off and pick-up times to ensure the children’s safety.
