This resource includes an audio archive from the April 2015 AAO Webinar case study of the Market Street Prototyping Festival in San Francisco. Host for this webinar was Neil Hrushowy, Manager of the City Design Group within the San Francisco Planning Department. This webinar focuses on the benefits of private-public partnerships to help municipal government improve their public engagement efforts concerning projects for the built environment. The webinar is 54 minutes long – a great primer for organizations interested in spearheading local design festivals or design competitions (or both, as was the case with the Market Street Prototyping Festival!).
