Is there seating at the Leach Ampitheatre?

I'm looking to get tickets for Al Jardine during the Waterfest on July 30th at the Leach Ampitheatre but ive never been to the ampitheatre before. As I would probably be going along with my elderly mother (and im not spring chicken myself) was wondering for those that have been there, is there seating available or is it all just more or less standing room like Summerfest is?
