Adaptation of the Ontario Nuclear Power Plant is a large-scale transformation of its lands, and is Intent/ The

focused on nature restoration, remediation, and renewable energy production and innovation througth the year 2050, as the site is decommissioned. The overall area of the Campus is approximately 120ha.

This initial plan begins to investigate the potential of landscape as a mechanism to reduce operating and maintenance costs, while generating quantifiable value to the Campus as an asset to Ontario Power Generation. The qualitative aspects of these changes will help to establish environmental stewardship and new understanding of the benefits to terrestrial habitat reconstruction as an overall amenity to the wider City of Pickering.

Ecological Design Principles The 2050 strategy presents an attempt at bridging the gap between economic, social, and environmental aspirationsof the site and an opportunity to decrease property maintenance costs, while also appropriating economic value to the site through a landscape strategy.

The Pickering Nuclear Power Plant lands are located in the area of the City of Pickering that is surrounded heavily by industrial uses. Opportunities to meaningfully repurpose the nuclear plant lands are hindered by the ample parking lots and impermeable surfaces present on site. This is compounded by the lands low ecological productivity given the presence of low

tree canopy and maintenance of manicured lawns which also presents heightened cost constraints. In contrast, the site presents opportunities to increase public and social capital given its location that is wrapped with a multi-use trail, and adjacent to multiple recreational lands including soccer and baseball fields.

Furthermore, we highlight multiple existing natural heritage lands and species habitats present directly on the site including the bank swallow nests along the waterfront, and the deer and peewee bird species habitat, which will ultimately support ecological productivity and networks.

Coral Reef Resilience/ Larvae Connectivity/ Mining and Forestry Operations/ Ocean Sensing

rate at which anthropogenic disturbances and climate change are impacting the Great Barrier Reef, Intent/ The

in Queensland Australia, is surpassing its regenerative capacity with up to half of the 2300km coral system succumbed to death in the last decade. The project transcends the narrative of independent coral study and dives into deeper examination of Queensland’s manufactured landscapes from; unregulated carbon intensive mines (contributing to climate change and coral bleaching) to tree felling (at a rate of 1000 rugby fields a day) in lieu of coastal industrial agriculture and ocean runoff.

The narrative advocates for a new regenerative connection across a 300km transect between land (reforestation of Goonyella mine for carbon sequestration), coast (restoration of Haypoint Coal Terminal and rerouted network of waterflows from industrial agriculture), and deep sea (regeneration of Molar Reef), all of which are emblematic of larger regional issues. The project explores the dynamics between time-sensitive ecological processes, responsive design strategies, and sociological interplays; ultimately asking what are practical yet meaningful restorative approaches for regenerating massive degraded landscapes like the Great Barrier Reef?

Mining Extraction Flows Australia today boasts 50,000 abandoned mines and a highly productive mining landscape due to minimal regulation on mining operations and lack of regulation for mines to be filled or cleaned up after operation. The country exports 15% of the world’s thermal coal while 90% of all mined product in Queensland is exported

overseas, ultimately contributing to intense carbon pollution rates, climate change, and coral bleaching. Many of the mines within the Great Barrier Reef catchment are kilometers long and wide and remain literal holes and scares on the landscapes.

Coastal Industrial Agriculture and Tree Felling Over the last decade, Queensland has continued to fell trees at a rate of 1000 rugby fields a day (314,000 hectares (2017-2018) much of the land is converted to industrial agricultural uses (The Guardian, 2018). Furthermore, poorly regulated coastal agricultural continues to be a source of algae bloom and thorn of the starfish outbreaks (COTS) in the Great Barrier Reef Heritage area. Up to 1000 adults can invade a single hectare of reef during an outbreak and infestation can destroy over 97% of a reef’s coral population (BBC One, 2015). On a similar note, the government of Queensland Australia has recently approved 1 million tons of sludge to be dumped in the great barrier reef region causing toxic water quality and choking of coral (Guardian, 2019).

Reef Resilience Hock and Mumby (2017) identify 100 reefs, accounting for 3% of the Great Barrier reef that are exhibiting characteristics of healthy systems and capable of promoting recovery located in areas that are; cool, protected please leave this area blank from crown-ofthorns starfish predation, and well connected to other reef systems through ocean currents with capacity to supply larvae (fertilized eggs). Recent studies also point to coral capacity of acclimatization and adaptation to rapid ocean temperature changes specifically with heat tolerant coral colonies forming partnerships after heat events (Baker, A.C., 2001, Kenkel, C. D., 2016).

300km Transect: Mine, Industrial Agriculture, Reef The project transcends the narrative of independent coral ecology study and dives into deeper examination of Queensland’s manufactured landscapes from; unregulated carbon intensive mines to tree felling in lieu of coastal industrial agriculture and associated poison runoff. The narrative advocates for a new regenerative connection between land (reforestation of Goonyella Riverside mine for carbon sequestration), coast (coastal restoration of Haypoint Coal Terminal and rerouted network of waterflows from industrial agriculture), and deep sea (regeneration of Molar Reef corals) while offering new human 18

agency to engage. The selected sites are emblematic of the larger regional issues in the region and a range of existing to novel landscape architecture strategies are explored to facilitate an ecologically resilient, connected, and productive landscape. This design research project re-configures the design workflow through design sensing, analysis, and process-oriented landscape systems to engage with the invisible ecological flows. Project drawings are communicated as processes and systems over time in contrast to static architectural representation in order to capture the nuances of regional geographies and dynamic landscapes.

19

300km Transect: Mine, Industrial Agriculture, Reef (continued) The spatial examination of the coastal industrial farming front reveals an artificial patterned landscape paralleling kilometer longstreams with no to minimal buffers. Hay Point Coal terminal, is a key node for coal shipment as well as intensive cattle grazing.

20

21

Reforestation of Goonyella Riverside Mine The primary focus is Goonyella Riverside coal mine in Queensland, Australia with a depth of 100m where a reforestation strategy is proposed to sequester carbon and support climate mitigation that is impacting the Great Barrier Reef as well as counteract the rates of tree felling in the region. The primary strategy towards returning the mine condition to its ecologically productive state involves the topographic manipulation and fill of mining holes.

The secondary purpose through this strategy is to promote new microclimate conditions through slope adaptations and water bed creation. The primary fill to cover up existing rock faces comes in the form of dredge material from shipping channels in the GBR heritage area presenting a novel opportunity. Currently, 22

sludge and other dredge material is being dumped into the Great Barrier Reef region covering and choking coral reefs.

The proposal adopts techniques of analyzing topographic formation in order to optimize planting schemes and desired microclimate creation through novel 3D tools including Ladybug and Bison’s topographic analysis tools (an extension of Rhino-Grasshopper).

Variables including height, slope, and degree of solar exposure based on the region’s weather data dictated the type of microclimate being created and necessary for specific forest types, and ultimately serving as a method of analysis for optimizing topographic forms. This on its own can serve as its own field of inquiry

bridging the field of landscape architecture and forest ecology.

In order to create the necessary top soil conditions for a productive landscape, regenerative cattle grazing is programmed with a layer of hay-mulch added onto the new land. This begins to remove pressure from coastal industrial farming as well as initiate top soil formation through feces decay.

From the new earth, underground seed vaults are proposed, taking advantage of the gapping landscape holes and which house seeds of a new planned forest. This will include the region’s native species including 51 species predicted to be extinct within

the next 10 years (Australian Government Department of Environment and Heritage). The underground structures will also remind the public of a deeper past through a glass façade that reveals a section of the earth where objects of the past industrial operations are left as archeologic remnants. On the surface however emerges a new diverse forest landscape that counteracts rising emission and climate change. The mining landscape restoration proposals combines a technical understanding of clean up after operation in addition to publicly engaging approaches.

Restoration of Coastal Hay Point Coal Terminal The spatial examination of the industrial farming front reveals an artificial patterned landscape paralleling kilometer longstreams and coastal ocean landscape with minimal buffers.

The select site, Hay Point Coal terminal, is a key node for coal shipment and is surrounded by cattle grazing operations.

The regenerative process is initiated by analyzing the water flow patterns through 3D landscape modelling. This knowledge begins to inform the spatial re-organization of manufactured coastal landscape patterns in order to mitigate poison runoff into the Great Barrier Reef Area. New embankments are subsequently proposed (using shipping channel dredge material as an opportunity again) and reroute the agricultural runoff flows from river and ocean zones.

On the new formed slopes, native coastal tree species from red 26

mangroves to Omreau bottle trees are introduced to stabilize the topography and counteract tree felling for agricultural land use conversion. Furthermore, an observatory tower is proposed to deck over this new landscape where farmers and locals are able to visualize new land patterning and the beginning of a rerouted network of water flows.

Using the existing agricultural land use patterns and modelled water flows, key drainage lines are designed approximately following the landscape contours, and ultimately laying the foundation for a new spatial restructuring of industrial agriculture patterns. As a tertiary layer to this spatial restructuring that connects with the key lines and creates an ocean buffer, fresh and salt water wetlands are re-introduced in lieu of the existing coal tailing ponds on site.

Regeneration of Coral Ecologies on Molar Reef The coastal restoration chapter is concluded with the introduction of new coral farming opportunities along the existing 2km coastal bridge that originally facilitated coal shipping. Both existing and novel farming opportunities are explored; from steel meshes that are electrically conductive, coral fragmentation that are capable of regenerating species up to 50 times faster, down to hand-size tetrapods where larvae is seeded and then transported off site for planting.

Along the bridge and through the ocean’s clear waters, farmers and locals claim new agency to these artificial and regenerative processes.

With the restructuring of Queensland Australia’s manufactured landscape system, coral regeneration on site begins to be more 30

impactful. The idea for coral regeneration is to engage on a present time scale where a spatially and technologically integrated slew of sensors provides feedback of coral reef conditions. Installed underwater camera domes are proposed to provide time sensitive imagery of bleaching events as well as COTS outbreaks. Sea surface and depth sensor products monitor both water and temperature quality through use of existing technologies including chemical composition, turbidity, light, and radiation intensity sensors.

The proposal begins to capitalize on reef’s resilient capacity by rearing coral larvae in nets during annual spawning. Reared larvae are then released on dead or dying reefs based on collected

sensor data speeding up the regeneration process via underwater drones (technology currently being prototyped by Queensland’s University of Technology). Similarly, a second set of drones is programmed to target COTS outbreaks and release a lethal injection. While smaller target interventions like individual coral plot planting may be effective for individual reef sites, the reality is, there is a need for scaling of restoration methods in order to effectively regenerate reef systems across the 2300km span, like the use of novel drone technology. And a targeted approach of restoring reefs that are most connected to others via larvae reproduction, first, is proposed in order to facilitate natural coral succession.

Regenerative Processes Timeline After a 30-year period (a calculated figure based on construction of landscape strategies as well as natural forest and coral growth), natural succession will take its course on the selected sites exhibiting hope for regeneration of the Great Barrier Reef. While on the one hand the design philosophy is to restore and reconnect these massive landscapes, the concept pushes for collective reflection on past action as well as agency on present to future conditions.

Exhibit The thesis was presented as a dystopic-utopic narrative of the required political and landscape processes needed to regenerate the Great Barrier Reef. The exhibition is framed as a boardroom meeting lead by ICRE (the Interplanetary Corporation of Resource Extraction), a multi-natinal fictional corporation of mining, logging, and industrial agriculture responsbile for the destruction of the Great Barrier Reef as a result of its extraction activiites.

After a high court rules on the culpability of the organization, its executives alongside landscape architects, ecologists, and other restoration scientists are required to spearhead the regenerative efforts acorss land, coast, and deep sea. The design research project is presented as a 360 interactive exhibit.

Stick in the Mud sesnsor calls attention to sediment as an essential resource in the Bay Area. In response Intent/ The

to rising sea levels, sediment is needed to support and develop wetland ecosystems along the urban coastline.

The (turbidity) sensor aims to bring awareness to sediment by rendering the fine particle movement visible to a larger public through light. The sensor can be deployed in a variety of coastal edges such as marshes, eelgrass beds and at the mouth of rivers.

The Underwater Eelgrass Meadows project mobilizes soft coastal infrastructure, with the capacity to grow and regress, to restore eelgrass meadows and promote public access and legibility. Eelgrass habitats are an essential nursery ground for fish species, act as valuable food sources for water birds and protect San Francisco Bays’ coasts from erosion and sediment loss.

Sensor Design The sensor aims to bring awareness to sediment by rendering the fine particle movement visible to a larger public. LED lights represent suspended sediment from a gradient of red to blue with red signaling turbid water and blue representing clear waters. Whether deployed in a group or individually, the lights visually represent turbidity and the impacts of sediment in a coastal condition.

The sensor is bluetooth enabled to allow for communication of sensor data to a GSM enabled station. Data from the station can be transmitted through a cell connection to a server to allow for

researchers and the public to access the sensor data. Solar panels are used to power the sensor to allow for long term deployment.

The sensor is designed to be easily installed and moved, the dimensions of the sensor connection are set to standard pvc pipe sizes to allow for simple height modification in order to adapt to different environmental conditions. The sensor can also be equipped with interchangeable caps including a drone visible top to facilitate data mapping according to the sensors precise geographic location.

2100, many coastal communities within the San Francisco Area will be highly impacted by flooding due Intent/ By

to sea-level-rise and storm surges. Eelgrass communities provide significant ecosystem services by protecting shorelines and stabilizing sediment, dissipating wave energy, and are an important food source for fish and bird species. This design proposal aims to heighten public awareness and citizen science involvement in the restoration of eelgrass meadows in the Bay area through an accessible toolkit, alongside adaptable coastal infrastructure modules.

The Toolkit is intended as a bottom-up approach to educate the public about eelgrass communities and facilitate resotration through a physical guide and materials for coastal planting. The Modules are designed to work in tandem with the toolkit as soft coastal infrastructure, with the capacity to grow and regress in order to promote public access and legibility during restoration. 1x1 meter adaptable boardwalk pieces are fabricated from wood panels and encase pre-manufactured floaters whereby the colour of the modules designates the restoration method on the sea floor. Underwater Meadows calls public attention and engagement into the process of eelgrass restoration.

53

54

Module The Modules are designed to work in tandem with the toolkit and as soft coastal infrastructure, with the capacity to grow and regress, to restore eelgrass meadows and promote public access and legibility. 1x1 meter adaptable boardwalk pieces are fabricated from wood panels and encase pre-manufactured floaters that propagate above water through a rope connection. While interchangeable bottoms are highly rugose (rough surface that promote habitat growth on the undersides), interchangeable tops engage the social landscape in the form of seating and undulating surfaces. Furthermore, coloured boardwalk tops mark specific

eelgrass restoration methods below and adjacent on the sea floor offering users a landscape legibility. The orange tops mark the seeding restoration method, the pastel yellow – TERFS method, the red – free planting, and the pastel pink is associated with the bamboo shoots method. In contrast to hard engineered approaches that attempt to control the natural environment, this project employs an adaptable and accessible framework that reserves the capacity to grow and be reversed concurrent to the restoration needs while maintaining a sensitivity to the existing landscape.

55

56

Toolkit The Toolkit is intended as a bottom-up method to empower citizens to work alongside scientists to develop thriving eelgrass meadows and monitor their results. The goal ofthe Toolkitis twofold; to educate about eelgrass communities and their value to the wider ecosystem, and to serve as a restoration guide (with physical materials) for citizens wanting to plant the coastal species. Eelgrass education includes the appropriate growing environment including their present location in the San Francisco Bay area, their ecological value for other species as well as for human ecosystem services, and their reproductive capacities. With regards to restoration initiatives, the manual describes four common restoration techniques that public members can easily apply including free or bamboo planting

(shoots are transplanted individually or in bunches and secured with anchors such as washer, rocks, bamboo stakes or popsicle sticks), TERFS (Transplanting Eelgrass Remotely with Frames System) where eelgrass shoots are attached to a wire frame, which temporarily anchor the shoots until they have rooted (4-6 weeks), and BuDs in which flowering eelgrass shoots are suspended in mesh bags attached to buoys and the seeds are slowly released as the shoots mature. The Underwater Meadows Toolkit provides the materials and instructions to construct a BuDS, Buoy-Deployed Seeding System. The guide is written for a younger audience to be used as an educational tool to compliment the toolkit.

Forest Depletion Causes and Species Composition

Site Classification of Productive Forest Stands

Temagami’s historical and current forest species composition shows a limited regeneration and growth of conifers and a favored regeneration and growth of decideous species. Fire suppression prevents the renewal of many pine species and supports shade tolerant species whose roots are able to penetrate the physical and chemical barriers.

Site productivity is the combined effect of physical and climate properties – soil depth, texture, nutrient load, precipitation, temperature, slope, elevation, and aspect – on tree growth.

Site Class is a measure of productivity and is the expression of the age height relationship of the leading species based upon Plonskis’ Normal Yield Tables, expressed as 0, 1, 2, 3 or 4.

Vertical Forest Stand Structure Vertical stand structure describes the number of distinct layers (stories) that can be identified in the stand canopy. Typically, vertical structure ranges from bimodel (two stories) to trimodel (three stories) during the canopy transition stage (120-140 years) of forest growth (Pare and Bergeron, 1995; Brassard et al. 2008).

Forest Gap Dynamics and Future Species ComposiHorizontal stand structure assesses the distribution of trees species and the presence of openings. Gap dynamics typically determine the types of species that will recruit in the open spaces. Small gaps are usually colonized by shade-tolerant tree species while large gaps allow greater amounts of sunlight to reach the forest floor, facilitating the recruitment of more shade-intolerant species.

Intent/ Transform

Forward [1]: Modern cities are evolving at unprecedented rates as mounting environmental,

technological, social, and economic pressures and disturbances force change. The city that upholds adaptable and flexible character will reap the future’s greatest fruits. The city of Toronto’s Rail Deck Park and adjacent lands present a unique opportunity to set the precedence for transformative urbanism, given the need for park land spaces in the city in contrast to competing forces. The proposed concept applies adaptation theory and explores the practicality of urban form and function that carries the capacity to transform as needed. Thus, the DNA of this design proposal is this form of pixelation which enables its transformation as individual pieces or as a larger network. Given the lack of available green spaces in the City of Toronto, minimal built form development is proposed on the rail deck in order to secure the space.

Phase [2]: Time is a meseasure of change. The existing heritage district as well as buildings deemed significant for heritage potential consituted the starting blocks to create new building frames and blocks. The new rail deck park is divided into strips, each with a unique identity to offer a multitude of experiences, activity spaces and communal uses.

Phase 0; The exisitng context.

Phase 1; The extremities of the site are built first including buildings and landscape. They are closest to already built areas and support early financial inventement from use for future development. Developpers build floor by floor and do not build to the skeleton limits giving them opportunity to procur future investment.

76

Phase 2; A secomd major segment of rail deck park is added, where buildings again are not filled to their full capacity. The rail deck landscape is active for use and is an opportunity to finance the remainder of the project.

Phase 3; The final phase of rail deck park is built. The buildings from earlier phases continue to be built incrementally floor by floor given developper and public financial capacities.

Building Permutations The design codes are applied to individual buildings on site and result in unique urban form that is capable of transformation.

Over time, developpers build floor by floor following certain rules, limitations, and freedoms. The designed built form is flexbile and allows developpers to add, take away, and rearrange blocks and uses to achieve optimal design and economic configuration.

The design consciously respects technical aspects of building architecture include building cores, setbacks and heights.

Landscape Permutations The rail deck is primarily maintained as a public park that accomodates a plethora of uses, with the capacity of being rented to private use. The deck is divided into zones and pixelated in 14m x 14m floor spaces that can be expanded to accomodate for larger public uses. Anchor built form such as trellises, trees, and unique architectural forms relate to anchor programs in each of the rail deck zones, and both perpetuate an identity of space. However, this does not exclude differing adjacent uses from occuring on those zones. This ideal further encourages urban transformation.

Infrastructure and Site Design The clearance required for rail passing forces the rail deck park to be elevated 2m, presenting unique infrastructure challenges in terms of park accessibility from Front St. This was tackled through modular approaches and the integration of differing modes of access including stairs, ramps, and storefronts connecting the adjacent street and park. The strategic implementation of infrastructural codes enabled full accessibility across main pedesrrian paths and roads onto rail deck park. Whle the proposed concept strongly values the rail deck as a public park network, building interior courtyards offer further opportunity for open sapces and are strategically located to contrast the exisitng context as well as enhance the connectivity of public and green spaces onsite.

Phase Phase through time

Phase through form

The new rail deck park is divided into strips organized by form according to the buildings that they fronts. Wave like ramps (Phases) inspired by the 19th century Lake Ontario shoreline front the newly proposed buildings, while flat plains with stepped entrances front the heritage (and heritage potential) buildings and the exiting streets. The park and adjacent development spaces are further divided into program zones according to the design form of spaces.

Play and activity spaces are dispered in front of the new development typologies, accentuated pedestrian corridors line up in front of the pedestrian streets, and heavily planted ecological zones in front of the existing heritage developments. Phase through movement is facilitated as users traverse the site encountering a unique and continuous pattern of narrow and open spaces.

Intent/ The

realities of climate change on island cities like Charlottetown in Prince Edward Island, Canada can no longer be ignored; adaptation must take place to avoid significant losses in the economy, heritage and built assets, and human health and life. In the wake of changing weather patterns, “soft design” that integrates Charlottetown’s natural and urban landscape is necessary for future resilient development. Softer design approaches that work alongside the natural processes will facilitate the use of ecosystem services as an opportunity for adaptive planning. These designed strategies will be applied to Charlottetown’s drosscapes, as a spatial opportunity for pressing water and snow management issues. Drosscapes are the wasted places such as contaminated sites, and the wasteful places such as oversized parking lots that emerged as a result of deindustrialization and rapid urbanization. Thus, the purpose of this proposal is to conceptualize soft designed adaptations utilizing Charlottetown’s drosscapes as a spatial framework.

Public Knowledge Exchange and Analysis A community based approach was applied to develop a richer understanding of climate change perceptions and build a focus for adaptation in Charlottetown. Public community members, and leaders including policy makers, planners, and architects were consulted through informal design charrettes. Originally, this consultation process is a collaborative session divided into structured components where designers sketch solutions to an issue. This same idea was applied to create interactive sessions for public and leader consultations.

Both public and leader forums were designed to systematically prompt comprehensive and analytic responses on climate change perceptions through a SWOT (strength, weakness, opportunities, threats) format.

The methodology is carried over from the marketing discipline where the concept is applied to analyze effectiveness of business proposals.

Climate Change and Drosscapes The city of Charlottetown is geographically located in a region that is subject to intense storm surges more than any other city in Atlantic Canada. The main impacts on the region, deducted from the consultations and scientific reports, include extensive flooding, intense storm patterns, and excess snow fall. Coastal and inland drosscapes (the wasted places such contaminated sites and the wasteful places such as oversized parking lots) are a significant opportunity for soft adaptation interventions. These spaces have the potential to be transformed into contaminant buffers, water infiltration and filtration landscapes for groundwater recharge, and be areas for managed retreats. By analyzing the locations of drosscapes across Charlottetown, it is clear they dominate the urban landscape which makes them spatially ideal as a physical framework for water management and snow storage.

94

Drosscape Typological Analysis Drosscape typologies were mapped throughout the downtown revealing an urban landscape of grey, hard and polluted surfaces.

Consequently, a typological analysis was undertaken to identify characteristics of the mapped spaces for effective design interventions. The spaces were analyzed by use as an independent factor because it was deemed a significant determinant in influencing proposed strategies. Following this, the data was categorized in total count, total land area, shape, scale, context, and land cover for a comprehensive understanding of the typologies. This analysis yielded significant findings that directed the overall design proposal and dictated the kind of interventions for each space.

95

33

Soft Design for Drosscapes The intention behind the proposed interventions is to transform Charlottetown’s Drosscapes through soft design into spaces that not only facilitate climate change adaptation but create vibrant spaces for Charlottetown residents. The approach is meant to address drosscapes at a smaller scale which then link together to produce a comprehensive urban strategy. This is proposed by envisioning public and private spaces that create benefit for the public good while adhering to their original uses. Two major approaches for drosscape soft design adaptation were proposed including a landscape of: networks and independent systems.

96

34

Network System

Independent System

The proposed network focuses on water management of inland flooding and ground water recharge (two main climate change issues in Charlottetown identified through the public and leader consultation process) by channeling water for ground filtration. In this approach residential parking drosscapes are transformed into permeable spaces, and open unused drosscapes as well as park spaces are transformed into constructed wetlands for ground water filtration.

The second approach for soft design adaptations in Charlottetown involves focus on the remaining typologies as independent systems in the city’s landscape. Public, industrial, and commercial parking and industrial typologies are significant contributors to water runoff and contamination from oil spills and sedimentation. Independent systems function for adaptation at the source including: open alley ways used for grey water collection; commercial, industrial, and public parking spaces adapted with vegetated buffers for onsite runoff treatment; and open industrial lands used for excess snow storage.
