It discusses two types of mixed-use projects - vertical, with residential over commercial, and horizontal, with residential and commercial in separate buildings. The guidelines aim to promote high quality design that enhances the pedestrian environment, protects bicyclists, designs parking to promote safety, ensures compatibility between uses, and encourages infill development with a mix of residential and commercial uses. Site planning guidelines address building placement, street orientation, parking location, and treatment of service areas. Architecture guidelines discuss creating an engaging street environment and building frontage.
