For a mixed-use project (1st story commercial, top 7 multi-family residential), in an urban setting (achieves Community Connectivity SSc2): can artificial turf on the roof deck contribute to achievement of SSc5.2? The project is nearly zero-lot line, and reference manual says we can include pedestrian oriented hardscape as open space (due to SSc2), can the artificial turf be counted? If so, would it be eligible as part of the vegetated area (required to be 25% of open space), or considered as pedestrian-oriented hardscape?
