We've got a development that owns propery on both sides of a major street in out city. They want to build a skyway plaza over the street to connect the two buildings. This plaza would be more than just a walkway -- they plan to have rooms, etc. This is a first request of its kind in our city of 47,000. How do we handle this zoning-wise? How do we deal with encroachments, since it goes over the public right-of-way? Any advice on how your cities have handled this would be appreciated.
