I recently submitted a topic proposal to the Urban Land Institute for its upcoming conference. The submittal is posted on the ULI's website here.
This is a brief summary of the proposed presentation:
A unique combination is in the works for real estate: (a) Younger families and urban professionals are pushing demand for exercise, health, and recreational-oriented options with their apartment, condo, and home residences and (b) Development and maintenance costs for the traditional golf course development model are far outpacing costs for other amenities, including trails. The successful investor and developer will be able to harness these realities into viable projects. What are the trends? What is required? How will success be defined?
Also, this is a recent National Publc Radio article touching on this subject: http://www.npr.org/blogs/thesalt/2013/12/17/251713829/forget-golf-courses-subdivisions-draw-residents-with-farms.
