OAKISLANDISH Lake Merritt | Oakland, CA la201 | fall 2015 | Kristina Hill Studio Lake Merritt is a unique metropolitan site that lies at the confluence of stormwater and sea-level rise, a scenario to be further exacerbated by future climate change. Working with a partner, we recognized that the lake serves as the central node of a larger network that connects the community to faunal, floral, and fluvial systems. Utilizing ‘Island Theory’ we created a series of interconnected nodes, each serving a different purpose such a recreation, stormwater, and habitat, to weave together a holistic solution that extends beyond the lake shore.

SWELL//SCAPE 75 Howard | San Francisco, CA la200b | spring 2015 | Walter Hood Studio As part of a proposed condominium project at 75 Howard, a new public space will be created in front of the development. The location of the site sat just two blocks from the bay, which drove the design to reconnect the condominium to the Embarcadero waterfront. The design sought to highlight the juxtaposition of the city and the bay by creating two polar and adjacent spaces. One represented the the bay by creating a tidal inlet with a wetland whose waters rose and fell with the daily tidal cycles. The other was a sunken basin to capture stormwater, representing the city and the terrestrial realm with its seasonal mediterranean climate.
Annual volume of rainfall on site ~20 inches / year
Daily change in tidal height ~ 6 ft 10
The concept embodied in this design was that of a wave wrapping around a peninsula and breaking upon the shore; the swell undulating as it rolls across the site.

INTERTIDAL HABITAT ANALOG Emeryville Marina | Emeryville, CA spring 2015 | Richard Hindle Prototype Development The goal of this project was to unearth construction innovations for common elements of the built environment using historical patents. I stumbled upon a series of patents that ranged from wave breaks, to harbor habitat provisioning, to new methods of embedding media in cast forms to promote algal growth. By adapting these systems I proposed a hybrid to increase habitat and anchorage for intertidal marine species in port and harbor settings.
14
CONCEPT MODELS: Early iterations (ABOVE) used planar materials to think about surface area and complexity. The second iteration of models used foam block to begin thinking about the physicality and broader range of form typologies. The latest iteration (RIGHT) moved into the realm of casting with plaster as I begin to think about the ultimate process of precast concrete modules. The concept is to design modules that provide for different niches within the intertidal zone so that they can be puzzled and interlocked together to create complex habitats that provide to a diversity of different species. The goal is a process based approach that provides for the earliest successors. 15

OYSTER REEF RESTORATION Wellfeet | Cape Cod, MA falll 2015 | Kristina Hill Studio This is a proposal to implement oyster reef restoration throughout Wellfleet harbor and the surrounding bay in an effort to improve water quality by reducing phytoplankton counts, reducing nitrogen levels, and providing habitat for other marine species. If implemented strategically, oyster reefs can also provide a wave break to mitigate shoreline erosion. The reefs are estimated to grow to a height of four feet within five years and to a density of 10,000 oysters per square meter. The state of Massachusetts recently enacted policy stating that cities and towns are responsible for their harbor water quality and the question is whether it is more economically and environmentally sensible to resort to a treatment plant or natural oyster reef filtration. The primary goal of the project was to create a photorealistic perspective to enable the community to envision what an oyster reef would look like at a place they recognize.

FILTERING POTENTIAL: The proposed area measured to 256 acres in size, which would yield approximately 10.3 billion oysters. Based on a water filtration rate of 55 L per oyster per day, an oyster reef of this size could filter 570 billion gallons per day or enough to fill 863,965 olympic sized swimming pools.

The project site is a reach of the North Fork of Strawberry Creek, a heavily degraded and artificially channelized creek running through the UC Berkeley campus. The design sought to holistically address manifold challenges, weaving together goals in restoration ecology, climate change adaptation, stormwater management, and academic and cultural utility of the site. This new mosaic rooted in stormwater management and native ecology envisions a multifunctional and floodable space - a critically needed and compelling Wall ‘evolutionary aesthetic’. contribution was the sectional and Overlook Graded Floodplain My graphic Protective Berm perspectives illustrating how the sites evolves with time.

Since campus development began in the late 1800s, the creek has been constrained by a series of check dams, culverts, and retaining walls - leading to severe channel incision, dramatic reduction of riparian buffer zone width, and regular drainage infrastructure failures.

The design re-establishes variation and connectivity in native ecotones by expansion of the floodplain and a major vegetation palette overhaul. Imagining the site as a valuable node of human interaction and observation of nature will catalyze the site and showcase seasonal rhythms.

Russian Hill, like Nob Hill, was urbanized realtively late, in the second half of the nineteenth century, by wayward Russian eskimos who chose its heights as ideal sites for their homes. This tradition was perpetuated and Russian Hill remains today an eskimo dominated neighborhood. The varied architecture, from igloo to Humbolt County “log” cabins, hippie co-ops and the occasional gothic rock group, all create a boisterous atmosphere of diverse, and bustling housing developments, longing for the clamor and agitation of the city. Some houses built in the early century can float in mid-air on their towering clouds after the streets were levelled and eliminated. The painter Bob Ross has rendered this energy in his painting “Happy Trees,” in which he expresses all the strange beauty of this urban landscape.
