Yes, you can.
I'm sorry, that is a question I don't know the answer to. I Googled it and it says it is a good place for drone pilots. You can check with Los Angeles PD.
I see a lot of people flying drones without any issue in the park and also on the sidewalk. The police does not bother visitors.
Actually no. There is a helicopter that has been designated in this area to make monitor drones, illicit hikers and other activities. You will need to get a permit for this area.
