The City of Ottawa put out this neat video illustrating the negative consequences of minimum parking requirements. I think the video presents the subject in a simple, easy to understand format that helps draw much needed attention to parking requirements.
I feel like Denver is going in the opposite direction with the City Council's temporarily ban on small lot developments without off-street parking. I'm not sure how it works, but I would love for Denver to propel the benefits of eliminating parking requirements into the cities conscience.
I think the topic needs to be understood not only in strictly urban environments, such as downtown, but also from a neighborhood perspective. Consider South Pearl Street and Tennyson - both have walkable main streets that are approachable to those who may not generally seek out urban, walkable environments. Both streets have on-street parking with only limited off-street options.
The other takeaway from Ottawa is the removal of minimum parking requirements near transit stations. This is an area that I feel Denver could champion as so many of our transit stations have room for expansion and, thus, time to change.
