The building at Lake Temescal is WONDERFUL. I guess I'd look under parks and rec. Also, have you checked out peerspace? Some great spaces there. Happy Birthday sweet 16!!
I had my baby shower (co-ed BBQ) at lake Temescal. We had a bunch of kids who could play on the lawn, fish, swim or play at the playground. They have bathrooms, parking and built in BBBQs. You can reserve tables in advance by calling the park district. February is hit or miss on weather so you would probably need a cover of some sort if it rains.
I had my baby shower at Lake Temescal and have since had our son's first and second Birthdays there. Each reservable site has a lot of space and there are play structures nearby. If you are unable to reserve a site there are some really nice unreserved spaces as well. Lot of parking too.
We just had a really nice birthday party at Lake Temescal and we reserved the spot in advance online. Most of them are close to the parking lots, have grassy open space for running around, and are close to drinking fountains and toilets. You can use the same link as the comment for Tilden Park and the website shows a picture of each of the picnic sites.

This doesn't really answer the question, but there is ample street parking near Lake Temescal; you don't necessarily have to pay the fee. In fact, if you drive by on the weekends, the lots are typically empty while the street fills up first. If you want to save $ that's a good place to start! Mary

We really like the lakes-Lake Anza, Lake Temescal...etc. Some are warmer than others, but all are beautiful, sandy, and fun for different ages. Kean
