The document discusses strategies for assembling land for urban redevelopment projects without using eminent domain. It describes how graduated density zoning, which allows greater density for larger assembled parcels, can incentivize voluntary land assembly.

The Canal Crossing redevelopment project aims to find a new model for large-scale redevelopment by addressing infrastructure issues and ensuring an equitable process. Rincon Hill in San Francisco also used owner participation agreements and rules to encourage cooperation in redevelopment.
