Mill Street Parking Ramp

The Mill Street Parking Structure is a 385 stall, 93,700 sf parking structure for the City of Wayzata. A cast-in-place post-tensioned concrete structure supports the second floor parking. A 15,000sf earth drilled/dropped lagging wall with helical tie-backs (engineered for placement at steep angles to stay within the tight property limits) envelops the north half of the site. The wall is waterproofed and has a cast-in-place concrete face wall with reveals and staining to further add artistic flair. Another innovative aspect to this project is the stormwater retention system which includes large diameter piping located underground adjacent to the structure to control drainage. Many residents have complimented the City’s new parking ramp with its “handsome looks” that provide both functional and aesthetic value to the neighborhood.
