Project generalized the LU codes in their FY 2019 parcels dataset to create a new attribute LU_general as shown below. Open space was added as a land use category by overlaying Boston’s Open_space dataset onto the parcels (open space taking precedence over underlying parcel land use designation). Dissolve on generalized LU codes. Overlay with city boundary (BostonCity_AOI) to identify ROW (anything not covered by parcels or open space polygons).
