The answer to this question is complex, as it varies depending on what part of the community the homeless individuals are in and the type of activities they are engaging in.
The Park is the ungated portion of Grayhawk and both streets and sidewalks in this area have public use easements meaning that homeless individuals, just like anyone else, have the right to utilize those sidewalks and streets. The same applies for the Grayhawk Neighborhood Park and Thompson Peak Park, City of Scottsdale parks found within the boundaries of Grayhawk.
That being said, there is not much the Grayhawk Community can do when it comes to sidewalks/streets as we cannot enforce trespassing on property that has a public use easement. If individuals are on Association private property (common area like greenbelts), patrol will ask those individuals to vacate the area and, if they do not, will call Scottsdale PD. Members of patrol are expected to observe and report and are not equipped to handle potentially combative situations.
The Retreat Village is the gated portion of Grayhawk found east of Hayden Rd. Everything within the Retreat, including the streets and sidewalks, are considered private property. While it is more difficult for homeless individuals to access the Retreat Village because it is gated, it is not impossible. Again, the Scottsdale Police Department will be called should patrol find individuals on Association property that do not belong there.
Trespassing
The Grayhawk Community Association (GCA) and Retreat Village Association (RVA) have both filed an application for what is considered a blanket trespass. This must be approved through the City of Scottsdale. If it is not approved, both the GCA or RVA would have to individually name and trespass each person on our property that does not belong there. This would be extremely difficult for the Association to manage and additional solutions are being reviewed in the case that the application is not approved.
