ON EXPLORING LANDSCAPES Exploring Landscapes covers two years of work in the Masters in Landscape Architecture II program at Harvard University Graduate School of Design. The work presented explores the relationship of landscape with ecology and civic infrastructure embedded within urban communities; and tests these relationships within the specificities of three design studios. The projects experiment with strategies to breakdown existing cycles of consumption and waste. These designs divert energy flows for the creation of multi-use, sustainable platforms that benefit local communities. Harvested dredge material from the New Haven Harbor creates a resilient storm surge buffer zone, which expands the city’s open space, and strengthens ecological corridors for waterfront recreation. On the Hudson River waterfront, a hybrid tree nursery - park generates an annual flow of urban-hardy street trees while acting as a center for community stewardship programs in the heart of Manhattan. The Concord landfill celebrates a revolving cradle to cradle landuse. A community waste landscape also performs as a recreation backdrop, and a home for enriched ecological habitats. This collection of work strengthens a belief of landscape as the foundation for environments, processes and operations; these are infrastructural landscapes, driven by human needs for development. Contemporary design solutions strive for balancing flows and resources by creating landscapes for the continuous benefits urban communities. The leader of these designs is the landscape architect: a trained generalist, which negotiates social, ecological and construction constraints into inspiring, and beautiful sustainable environments.
ACKNOWLEDGMENTS I’d like to acknowledge my friends, family and colleagues in the US, Israel and abroad who supported me throughout this process - always willing to help, offering a hand, good advice and just being there for me. Special thanks go to my wonderful parents Tirza and Doron, and to my amazing wife Sivan. Your belief in my abilities and goals made this dream possible.

Dredged sedimentation from the harbor canal and bay area will be reused to extend New Haven’s water front. The design performs as a protective surge buffer zone, which regenerates the existing narrow and eroded waterline into a productive and resilient dune park.

The centralized location within New Haven, creates an iconic landmark for the city. The shape and dimension of the dune echoes the historical settlement and cultivation of the area, making it a physical and educational reminder of New Haven’s footprint.

PARK STRUCTURE SCHEME

PARK PLAN Implementation of the project is performed over time, starting with the foundation of the break wave system, and responsively to resource availability. The land fill forms the beach and primary program area, the nature reserve and the high points of the park. The circulation system is based on the first phase of construction, allowing functionality throughout the park construction phases.

The Gansevoort Park and Tree Farm encourages the community to experience and engage in a unique, productive and dynamic landscape. The spacious seven acre pier transforms into a hybrid of production and recreational infrastructure. The park hosts a self-sustaining, urban-hardy tree nursery, and its programing acts to increase human sensitivity to natural cycles of growth within the Manhattan city-scape. Community planting programs would follow the trees growth cycles, from plugs to fully grown street trees in the neighborhood. The

park conserves the original pier shape while transforming it into seven acres of production landscape. The restored seawall frames gentle manipulations in topography. A runoff catchment and circulation system is installed, minimizing the parks potable water consumption.

The typology mixture defines the park’s productive profile, number of trees exported annually and its recreational profile. The operation of the park adapts to community needs by replanting, thinning of rows and clearing space for recreation purposes.

The park contributes approximately 200 grown street trees annually to the adjacent neighborhoods as part of a self-sustaining operational strategy.

The vegetation list consists of native species that appear in local Flood Forest and the pre-developed Manhattan habitats. The Proposed plant list Overlaps with current NYC street tree list. It suggests six medium-fast growing street trees that hold similar growth characteristics.

The planting pallet would expand over time, and introduce new species to the city street-scape. This will increase biodiversity and strengthen the urban tree-scape resistance to tree diseases.

Walden, the pristine iconic view of a New England ‘nature’ as reflected in the clear pond water was the perfect setting for the myth and mystery surrounding Henry David Thoreau. The pond, its depth and its presence highly influenced him and became a physical center of his ideas. In the winter of 1846, Thoreau revealed the pond’s great depth, relating it to inner human strength and depth of soul.

Swimming encompasses the harmonious repetitive body movements of the swimmer. The ripples on the water surface, reaching outbound to the shore, and the embryos feeling of the water fosters no external stimulations, just echoing of thoughts. This sensual experience simultaneously poses great vulnerability and anxiety from the forces of nature, and one’s hidden submerged fears. Swimming is praying, a mantra which enables deep contemplation and spiritual catharsis.

The linear process of consumption and waste, that ends in a covered landfill outside a town or municipality has left its footprint on the landscape; it has become recognized as part of the urban fabric. This potentially advantageous landuse typology holds opportunities for rethinking and intervention. Concord landfill demonstrates a new role for landfills in the metropolis.

Located 300 meters from Walden Pond, the adjacent Concord Landfill appears as a calm and deserted site. The beautiful meadow, of Bluestem and Spartiana carved out of Walden Woods doesn’t indicate its past landuse or the history buried beneath.

The site acknowledges the contemporary urban waste process by inviting local waste operations to become a part of the community. The revolving landfill is an evident, regenerating and physical reminder of Concord’s consumption footprint over a 30 year life cycle. The 10.7 hectares demonstrate resilient open space uses, while exploring new opportunities for recreation, and enhanced ecological diversification.

The hydrology design contributes high quality filtered water to the system and prevents leachate contamination. The lined landfill acts as a local catch basin, which receives runoff water from the highway. The basin does not penetrate to Walden Pond’s ground water system due to the liner and leachate treatment pools. The runoff water filters through the wet and mesic prairie habitats, decreasing the nutrient and contamination level before entering the vernal pools, which percolate to Fairy Pond ground water system.

The opportunities that lie in using the sculptural and dramatic shape of the landfill as a recreational working landscape are exciting and challenging. Waste degradation and habitat establishment coexist with a hyper-recreation platform, while demonstrating community responsibility and environmental justice.
