This paper was originally written by Lina Menard of Niche Consulting LLC in June of 2012 as a term paper for a course she took as part of her Masters of Urban and Regional Planning Masters program at Portland State University. The course, USP 510: Planning & The Housing Market, taught by Dr. Lisa Bates, focused on the intersection between planning, regulation, and affordable housing. This version of the paper was updated in January 2015.
