Project Profile:

Athletic Practice Fields, Tulane University

Project Summary

Dealing with the high water table is problematic for Tulane Univeristy and all of New Orleans. Designers from Gould Evans Associates and Lee Ledbetter & Associates needed a way to store the site'srunoff from stormwater while maximizing the limited area for an athletic practice field. Rainstore3 was chosen for the detention system in onechamber with two heights: one sectionat 5 units high (50cm) and the other area at 7 units high (70cm). Precautions had to be made in the design of the system as the water table will exert upward force on the chambers at different times. Designer ended up wrapping nearly all of the sides of the chamber (leaving the top for infiltration) with a impermeable membrane. Calculations were made to see how buoyant this made the Rainstore3 system. Then designers could counteract the upward buoyancy pressure with static pressure from the cover material and athletic field surfaceturf preventing the system from "floating" or popping up. The chamberiscapable of holding 1428 cubic meters (50,000 cu ft) of stormwater.
