City property exists in various states and for various reasons. Some open space has been designated as conservation area because of its delicate ecosystem, unique terrain, or any other value it provides to plants, animals, etc. Some spaces that may appear to not be in use are actually used for irrigation, for providing city services, or other reasons that aren’t easily visible. And even further space may have been designated for future use that requires maintenance until the time it becomes further developed. For many reasons, we are required to care for public city property in a way that benefits us all, not a single private property owner.
