Which of the following developments is a 75-acre redevelopment in San Jose, CA designed by Peter Calthorpe?

The correct answer is Jackson Taylor. This development is a significant 75-acre urban infill project located in San Jose, California, designed by renowned architect and urban planner Peter Calthorpe. Jackson Taylor exemplifies principles of smart growth and sustainable urban development, focusing on creating a vibrant, walkable community by integrating residential, commercial, and recreational spaces within a thoughtfully designed environment.

The other options, while notable developments in their own right, do not pertain to Calthorpe's work in San Jose. Laguna West is known for its new urbanist principles but is located in Sacramento; Kentlands is a celebrated example of New Urbanism located in Maryland; and Edge City refers to a concept in urban development rather than a specific project. These projects are often discussed in the context of urban planning and development but do not represent Peter Calthorpe's work specifically in the San Jose area.
