Code Enforcement assigned this issue to Parks

Thank you for bringing this to our attention, we do have some signage on 119th & Sheridan that is displayed during events. The washrooms were open during this event, it is unfortunate that some did not utilize the washrooms provide.
Announcements during events as to washroom locations is a great idea (thanks), we will definitely make sure that is implemented.
We greatly appreciate your suggestions and will make sure the park staff and event coordinators are made aware of this.
Have a great day & thanks for using Whiting311.
