Demolition of Downtown Parking Structure 3 is approved May. 15, 2021 at 6:00 am Garage: Coastal Commission has approved the removal. Todd James On Thursday, Coastal Commission approved the demolition of Parking Structure 3, allowing the City to advance its efforts to build an affordable housing development on the lot. The decision, which was met with opposition from some community members and Downtown business owners, grants the City permission to demolish the structure, repave the land and install a fence around the property. The structure is located at 4th St and Arizona Ave, in close proximity to the Promenade, and contains 337 spaces. Commission staff primarily based their recommendation on a study by Walker Consultants, which concluded that the loss of PS3’s spaces would not adversely impact parking availability and coastal access in the surrounding area.
