GREEN STEEL Brownfield Redevelopment of the Carrie Furnace Pittsburgh, PA
Brownfield Redevelopment, Planning, & Site Design
Project Statement The Carrie Furnace is a brownfield site that offers an opportunity to revitalize the local neighborhoods through development of sustainable infrastructure that encompasses open public space, artistic exhibitions, connections between recreational trails, a riverfront connection, in addition to quality jobs. The historic significance of the site makes for a special opportunity to capture the heart and soul of neighborhoods and serves a wide variety of users. The
intent is to holistically redevelop the site by avoiding past mistakes of a single-use program of retail chains and embracing the inherent complexities with the capacity to remain vibrant, and retain value for future generations to come. The Green Steel proposal hopes to alter the negative perceptions attached to brownfields and be a model for future public reinvestment projects in the Pittsburgh area and other cities across the nation.

Ecological Time Signature
Interpret change in time through the landscape Bodega Bay, CA Student Housing & Ecological Site Restoration
Project Statement The Bodega Marine Lab Housing enclave remains an ecological focal point where highly intricate vegetation and fauna typologies meet. This interdependent relationship remains concealed to many of the immediate users as its current state continues to degenerate toward
23
a monotonous habitat. This project applies architecture and landscape design synergies to facilitate environmentally sensitive housing demands, restore habitats, and frame their ecological time signatures to inspire exploration of the natural world.

Approach The aim is to restore habitat typologies to preserve the ecological value of the site. Soils, plant communities, and microclimates vary widely due to a variety of geological factors associated with contact to the Pacific Ocean and the San Andreas fault line. Further research divides the site into four key habitats. The first, starting from sea level, is the intertidal mud flats out toward Bodega head. The second is the brackish wetland

ascending toward the site. The third and fourth are grasslands and sand dunes that surround the majority of the housing enclave. Primarily, the introduction of non-native vegetation to prevent sand dune erosion that would otherwise collect in the bay has shaped much of the regional landscape. Capturing opportunities to improve the ecology of the site will help offset the needed housing expansion.

BRIDGE PERSPECTIVE The boardwalk draws attention to the tidal fluctuations that permits or restricts access down to bay. The mud flats can be reach by passing underneath the proposed bridge during the period of lowest tide. During other
periods, sections of the boardwalk is hidden under water to visually interpret the tide cycles. In addition, the program manipulated the grading of the land to address the long term sea level rise implications.

During the rainy season, the large walls act as runnels to channel run-off passed the built environment to reduce contact with potential contamination and be captured for water re-use. Once enough water is captured, it is then directed to create new water habitat pools to support other types of fauna as it falls over the edge; simultaneously creating a peaceful sound. Bio-swales capture remaining water run-off along the hillside and the roadway and is directed into a rain garden.

Architecture & Space Program Current figure ground organization has been piecemeal together as the demands increase resulting in a physical, social, and aesthetic disconnect. The architectural design utilizes large walls positioned within the hillside that arrange space in linear sections to help withstand against earthquakes. The walls act as a spine that allow a sequence of contrasting exterior and interior rooms, large gathering areas, and pockets of intimate space.
A roof envelope unifies the light building footprint in order to protect users even while outside. Light wells are placed in the center of deep rooms to provide ample day and night light that also compliment pocket gardens. The arrangement of the visitor center, exhibit space, offices, meeting rooms, in addition to living quarters allow the site to be utilized by a variety of people. Parking remains hidden along the spine to provide access in proximity to user destination.

The arboretum waterway suffers from a
lack of landorms, microclimates, and a strong visible identity. By manipulating the landform with a series of islands and an indulating shoreline, the underutilized open areas are captured to create additional
edge habitat for vegetaion and fauna. A boardwalk that integrates a shade-structure connects the two far end of the bank and is designed to highlight and celebrate nature. The shape is inspired by a wave in constant motion in a still detention body of water.

Sharp Park encompasses diverse habitats including coastal wetlands & scrub, forest, and grasslands. The current golf course spills graywater off of adjacent roads and neighborhoods into the sensitive brackish wetland due to backed up piping systems. A
passive tiered constructed wetland and regenerative water ponds utilize gravity fed phytoremediation to treat graywater before reaching the sensitive habitat where endangered species reside and are observed by visitors to the public park.

The Broadway corridor has remained a gateway and central hub to the city of Sacramento for many urban dwellers. A plan was developed to make the corridor a welcoming and friendly place that engages the community to live, work, and play. Strategies regarding pedestrian safety were addressed with ‘complete streets’ and is complimented
37
by strategically re-introducing the streetcar in the region to enable a safer, pedestrian friendly transit based infrastructure. The planning of mixed-use, public open space, recreation, and community interest facilities help develop under represented public housing inhabitants to reinforce the rich and artful identity of the region.

Strategies that Promote Levee Failure This 73 acre reserve is the largest remaining riparian forest along the river that promotes exploration and environmental education. The levee has caused faster deeper river flows, undercut of banks, erosion, and reduction of fish spawning areas. Two strategies are proposed to improve the quality of the river.
The ‘Minor Setback Levee’ address sensitive vineyard edge while the ‘Major Setback Levee’ breaks down the existing barrier to allow water to naturally enter the flood plain and restore it to its natural state while recharging the water table and providing flood relief further downstream. CK BA
