Semester: Fall 2020

Project Type: Master Planning + Urban Design

Designer: Ryan Blair

This project involves two tiers of design: (1) Hill District masterplaning, and (2) Lower Hill District land development plan. The first tier of this project addresses a number of goals included in the Green New Deal through strategic infill development proposals in concentrated areas as eco-districts. This development will reduce CO₂ emissions by coinciding with an increase in transportation infrastructure along with transit-oriented development - as Pittsburgh is the 7th least car dependent city in the U.S. Historically, much of the cultural activity that took place in the Hill neighborhoods occurred in the streets – something that has been lost in recent decades. To revive this character, redevelopment will be concentrated into three individual eco-districts that will be linked by way of the Wylie Greenway, and to surrounding public greenspaces.

To reestablish the connection between the Hill District and downtown, the Lower Hill will be redeveloped in a way to create an economic and cultural activity center. To ensure the connection, and serve the many residents of the Hill who rely on walking, biking an public transportation, the circulation design in this eco-district should be prioritized for the flow of pedestrians and public transportation. This will be accomplished by designing a "superblock" structure, keeping vehicular traffic to the exterior while preserving the interior for pedestrians. By addressing issues such as transportation, density and low economic activity through both a comprehensive masterplan of the Hill District and a pedestrian-oriented redevelopment of the Lower Hill, the Hill District will have the opportunity to return to the vibrant community it once was.

An analysis of existing characteristics points to a number of issues in the Hill District. Topography in itself creates a consequential movement barrier to and from the Upper and Middle Hill Districts. Vacant lots resulting from the urban renewal efforts left a significant amount of vacant lots within the Hill District. Lastly, a walk-shed analysis provides insight into how difficult it may be for a resident to get to and from the hill district via non-car commuting.

"SUPERBLOCK" CONCEPT

Using the concept of a "superblock", or urban cell defined by peripheral main roads, will insure the free flow of pedestrians through the greenway and increase safety. In this design, preference in given to pedestrians, cyclists, and public transportation. This design also increases public space by upwards of 70% by preserving areas that would otherwise be streets.
