Divided Connection
Divided Connection
Location: Pittsburgh, Pennsylvania
Course: LARC 652
Semester: Fall 2021
Project Type: Master Planning & Urban Design
Designer: Olivia Sinclair
Goals:
Increase green space
Enhance pedestrian & bicycle connections & conditions
Create connection from nearby neighborhood
Improve vehicular circulation
Maximize sustainable flood mitigation solutions
Existing Site
Existing Networks
Existing Block Pattern
After site inventory and analysis, the site appeared to have multiple vacant lots, lack of green space, and poor hierarchy of vehicular and pedestrian circulation. The lack of pedestrian priority consequently does not allow many access points to the site from nearby neighborhoods into green space. Vacant lots are stagnant and classified as currently as brownfield sites.
Building Footprints
Network + Circulation
Green Space
By maintaining the grid pattern network and circulation, the vehicular and pedestrian circulation can coincide. A pedestrian and bicycle route has been created to establish a connection from nearby neighborhoods of Troy Hills through the site to views of Downtown Pittsburgh, and the Strip District. The existing pedestrian bridge has been preserved to maximized its potential as a corridor structure. Public transportation to the site is available by bus and the addition of a platform train station off the existing railroad. As a transportation hub, the train station is one of the main stopping points along the non-vehicular road, along with space to rest near food and drink, and public open space that hosts scenic views.

Flood After Design
The open space is a major point along the pedestrian corridor that host many features - rainwater gardens, public seating, plaza, splash pad, fountains and open lawn. The red brick pattern that is common in the city of Pittsburgh is carried throughout the design of the space along footpaths dividing the programed spaces. Fountains outside of a large hotel building mimic the Heinz Factory chimneys. The same style is used for the splash pads in the splash pad area. The rainwater gardens, retention ponds and sustainable pavement materials are the main sustainable practices to mitigate flooding in this space.
