is this space at marina available to reserve for large company picnic?

Depending on how large the company is. Their picnic areas are pretty big and so is the field. I would look up how many people the picnic areas can accommodate on the San leandro park and rec website

Yes, this truly one of the best places to go out and play picnic, and have BBQ. Large grass to play ball. Or have hugh party for children. Plus it right on the water. Mile running course par exercise and fishing. Thats one of my favorite places ever. Thanks JohnHann

Is the big area at marina available for rent this sat 4/14/18 7 am to 7 pm with amplified music permit?

Yes!!

The park at a really big you can accommodate at least 30 to 40 people they do have a feel they also have volleyball courts and I do believe they have a softball field you won't have a whole lot of fun there in the scenery is great

Agreed. It will depend on the size of your attendees.

👍 yes

Park is very large, i do mean large but calling in advance is alway best .. now i know they have lots of picnic tables that you could put together with help. Its a great a peaceful park with the atmosphere meaning the bay right behind you a great for public speaking..

There is a number of areas that may be suitable. Yes!
