The Cardinals and Texans have gone to extraordinary lengths for natural grass. The Cardinals' rollout grass field is placed inside the stadium for games and parked outside in sunlight on other days. The Texans' field is assembled from eight-square-foot trays of grass and replaced periodically during the season with fresh trays grown nearby.
In addition to the sunlight issue, Falcons president Rich McKay said the plan to use the Atlanta stadium for many other events complicated the idea of natural grass.
“We did everything we could to solve for a grass field,” McKay said. “But this will be a true multi-purpose building, and it’s going to be used a lot. That change-over presents a lot of problems for grass.”
If Atlanta gets a Major League Soccer team for the stadium, it would play on artificial turf, McKay said. But a temporary grass field occasionally could be installed for events such as international soccer games that require it, McKay said.
