Technical Brief: Rethinking Parking Requirement Exemptions with Spontaneous Accessibility

Rethinking Parking Requirement Exemptions with Spontaneous Accessibility proposes Spontaneous Accessibility as a mechanism for determining when developers of new residential or commercial sites in Seattle should be exempted from providing parking. Currently this decision is made by evaluating access to frequent transit using a distance and headway-based process. Replacing this process with Spontaneous Accessibility measurements incorporates additional precision and nuance, better determining whether new parking-exempted sites are truly served by transit that can meet the entirety of resident needs. Though focused on a single problem in Seattle, it provides a framework for using Network Accessibility and Point Accessibility to solve land use problems generally.
