The Pima Association of Governments (PAG), in partnership with OpenTopography, has posted their most recent high-quality USGS 3DEP LiDAR dataset as open access, allowing anyone unrestricted access to the data and processing tools available in the platform. The first dataset, AZ PimaCo 2 2021 USGS 3DEP, covers the City of Tucson and its surrounding area.  An additional Pima County 3DEP dataset over portions of the western part of the county is coming as soon as the dataset is published by USGS.
