Park - Tot Lots, Tables, Benches Acknowledged2532 Coolidge Ave Oakland, CA, 94601, USA - Peralta-HaciendaAt the Peralta Hacienda Park there is always a loud gathering/party at the lower creek level, at the picnic benches, with very loud music playing on speakers and littering of beer cans and such. It is very disruptive when my family and I just want to enjoy the park. We have been living with this disruption for many years and are finally really frustrated enough to report it. Please let me know who I should call when I see them there during the day, the police?? Thank you.
