Supporting Research and Data
What makes the Sequoia proposal compelling is that it is not founded upon speculation. While it is novel in its approach
to solve for varied problems within a singular concept, all of its suggestions and components are founded in real world data and research with successful outcomes. Below is a bibliography of case studies and research that corroborate the validity of the various elements of Sequoia's proposal for Market Street in San Francisco.
