This is the criteria clarification for picnic areas:
I’ve only nominated one picnic area - a collection of tables and benches in a business park. Rejected initially by the community and after that by ML, but accepted at appeal. I only nominated it because it was a group of seating rather than a single table, which enhanced its social value. Also, because it was featured as promotional material on the website for the company that ran the business park. I felt that meant that the social importance of the picnic area was elevated in the context of that area.
