“Is it legal?” Dan Slone has been answering that question regarding codes for 25 years. He has written or helped write traditional neighborhood development codes, Smart Codes and other form-based codes for communities across the country. He’s written codes for developers seeking project approval in local communities, and codes for communities trying to implement traditional neighborhood designs for sustainable development. Dan is national counsel for the Congress for the New Urbanism, the Seaside Institute and the U.S. Green Building Council. He lectures nationally on overcoming impediments to innovative development and on the legal aspects of form-based codes. He is the co-author of a new book with Doris Goldstein, entitled A Legal Guide for Urban and Sustainable Development for Planners, Architects and Developers.
