Table 4.6-5 Parking Structure Screening Methods
Storefront with Active Use – Often referred to as a “wrap”, this includes locating an active use such as, but not limited to, retail, restaurant, office, residential, commercial, or civic space between the parking structure and public space.
Public Art – Using public art, such as a mural or sculptural element integrated into the façade.
Display Cases – Display cases could be used to display retail goods, art, banners, and more.
Landscape Wall – Incorporating green landscaping into the façade of a parking structure at the ground floor also provides interest. This can be done with vines, vertical gardens, or other living plant material.
