If you are having an event at the botanical gardens it is best to use the parking lot in front of the building. You do not want to use the parking lot to the left as that belongs to the school that is there.
Parking for an event is open. And for any overflow, the service road works. We have provided a shuttle service with our events help at the garden.
There is a lot of parking there. Last time I went I saw signs with arrows for event parking.
