SANTA CLARA (KRON)—Grounds crews were out Tuesday putting down new turf at Levi’s Stadium.

A new grass field is laid out six to eight times a year at the stadium because it is a multi-functional facility, said Roger Hacker of the San Francisco 49ers.

The team plans for this every year.

The NFL has putting down a new grass field before every Super Bowl since the 1990s, Hacker said.

The San Francisco 49ers are scheduled to take the field this Sunday at 4 p.m. for their first preseason game of the year.

The Houston Texans will be in Santa Clara.
