Baseball Facility Employs Storm Water Management System

Sept. 13, 2017

A new franchise in the 12-team American Association of Independent Professional Baseball is coming to the village of Rosemont, Ill., in May 2018. To house the new team, a 6,300-seat baseball stadium and adjacent 1,200-space parking deck is being constructed on approximately 10.3 acres just west of Interstate 294.

In order to comply with the storm water management requirements set by the Metropolitan Water Reclamation District of Greater Chicago (MWRD), a storm water infiltration and detention solution was needed. Due to the necessary structural integrity and amount of storm water detention required, pipe was not a viable option to meet the storm water management needs and StormTrap was specified for the project.

The solution chosen for this development was an 8-ft-2-in. DoubleTrap system to be located beneath the parking garage. To fulfill the volume control best management practices requirement, StormTrap provided precast openings in the bottom pieces of the system, allowing the volume control capacity to slowly discharge back into the soil, which will recharge groundwater and provide water quality advantages. The entire design provided a total storage capacity of 125,993 cu ft, exceeding the MWRD requirements.

Open communication and responsive teamwork were essential components in reaching an effective solution.

"We had to make numerous revisions to the plans after the first StormTrap system was designed, and StormTrap worked with us to make the necessary modifications along the way," said Trudy Buehler, senior project manager for Mackie Consultants.

The system was originally designed to be two basins; however, due to spread footings and grade beams with vertical loads supported by caissons, the first basin was split into two separate systems, resulting in a series of three basins in order to work within the structural components of the parking deck. The modular design of the system allowed the total acreage to be used for the development as opposed to sacrificing valuable land or compromising the structure for storm water management.
