Executive Summary The goal of this project is to create a vision for Oregon’s energy landscapes, driven by green stimuli, as a response to the COVID-19 pandemic and climate change. Using energy transition to phase out fossil fuel as a core principle for a more resilient and just future, we investigate the impact of climate change in Oregon, Oregon’s renewable energy portfolio, and the spatial impact of energy transition. Case studies on collocating renewable energy infrastructure with other types of land uses, to increase land use efficiency, were surveyed and we discussed potentials for applying them within Oregon landscapes. Finally, we use a transect approach to illustrate how Oregon’s urban, suburban, rural, and coastal landscapes can be transformed. With proactive planning and innovative design approach, our proposal demonstrates that Oregon can mitigate and adapt to climate change through 1) designing a hyperfunctional urban core, 2) retrofitting suburban landscapes to harvest green energy, 3) supporting sustainable and just rural communities, and 4) building resilient coastal small towns. This work was done entirely through online teaching and remote teamwork under the COVID-19 quarantine in Spring 2020.

Urban Core Suburban Rural Coastal
Introduction In 2020, the world is experiencing an unprecedented societal crisis caused by COVID-19. Many local and national governments have been quickly offering stimulus packages to re-boost the economy. While the economic and social impact of the pandemic is substantial, our response to the pandemic can be an opportunity to mitigate climate change, the other urgent catastrophe that the world is facing with only a decade of a time left to act. Many cities, businesses, and local and national governments have already started a discussion on how they can use their stimulus for a more sustainable future by building resilient infrastructure and supporting marginalized communities through green jobs; some call this movement a “Green New Deal”. Among many important principles and strategies, the central action for mitigating climate change is a transition to low-carbon and resilient energy systems through increasing energy efficiency, renewable energy, and energy storages. How can we promote rapid energy transition that can support cleaner and just economy? The answer to this question is much more complicated than setting an impressive renewable energy goal and putting solar and wind farms wherever possible. Since renewable energy sources, including solar and wind energy, require a relatively larger land footprint than conventional energy source like coal and petroleum, renewable energy development has been the largest driver of land use change in the United States and the world in the past decade. There have been numerous land use conflicts in rural communities and wildlife habitats and approaches discussed to resolve such conflicts. Given these challenges, it is important to think about the spatial impact of energy policy and how to mitigate conflicts to achieve our energy goals, while not sacrificing social, cultural and ecological values. Therefore, our main questions in this report are:
6
• Where and how should the energy infrastructure be situated in the urban, suburban, rural, and coastal landscapes of Oregon? • How can landscape planning help to resolve conflicts between renewable energy structures and existing land use? • How can landscape design increase multiple co-benefits and land-use efficiency? We used the seven major principles of the Oregon Green New Deal, developed by a coalition of various community organizations in Oregon, as our underlying framework and developed our own core principles: • Phase out fossil fuel and rapidly transition to renewable energy • Build community energy independency, self-sufficiency, and democracy • Support community resilience through diversity, redundancy, and • • • •
decentralization Support equity for marginalized and vulnerable populations Design place-based multifunctional and hyper-functional landscapes Protect ecosystems by increasing land use efficiency Improve aesthetics to address the public perception on energy infrastructure
The Green New Deal can be disastrous when it is not thoroughly planned and followed by an adequate process. Due to the nature of stimulus packages, a large amount of money has to be flushed out within a short amount of time and this often results in a top-down policy with minimal consideration for a place-based solution. Our goal is to proactively visualize how we can envision our post-pandemic future through sustainable energy landscapes using the State of Oregon as our case study. We took a transect planning approach that illustrates how urban core, suburban, rural, and coastal landscapes can be transformed through green stimulus in Oregon.

URBAN CORE
Resilient coastal small towns
Sustainable & just rural communities
Harvesting renewable energy from suburban landscapes
Hyperfunctional dense urban core
How can we design for coastal small towns to integrate renewable energy systems that are resilient to rising sea levels and big earthquakes?
How can we integrate renewable energy production in rural communities as a way to support farmers, marginalized rural residents, and Indigenous people by boosting rural economy, respecting rural culture and landscapes, and protecting ecosystems and culture?
How can we retrofit suburban areas to incorporate renewable energy generation and multifunctionality using the emerging land opportunities (e.g. parking lots) and unharvested surfaces (e.g. rooftops)?
How can we design a dense urban core that is hyperfunctional to maximize on-site renewable energy potential, implement decentralized energy systems, and manage trade-offs with resilience and other uses?
The key strategies for the four transect zones are:
1. Hyper-functional dense urban core
3. Sustainable and just rural communities
• Addressing limited land resource availability per capita • Addressing pressing needs for increasing land use efficiency
• Seeking co-location strategies generating extra revenues for
through co-location (BIPV, PVs on transportation infrastructure, urban agrovoltaics, brownfields, etc.) and built surface utilization (e.g. green walls in building façade) • Identifying hot spots that have conflicts of different uses and/or most vulnerable • Exploring innovative design approaches for multifunctionality and hyper-functionality (synergizing the advantages of engineering approach and those of a nature-based approach) while managing trade-offs
2. Harvesting renewable energy from suburban landscapes

Oregon and Climate Change - David Pauls and Sam Alig
Research question How will Oregon’s climate change by 2050 and 2100?
Background research Effects of climate change on oregon Temperature As global warming’s effects take hold Oregon’s climate is expected to warm from 4 to 9 degrees by 2100. The increase heat and droughts will make wild land fired more frequent and extreme across the state. As well having shorter, warmer winters and springs, leading to longer hotter summers. The coast will have less dramatic effects as the proximity to the ocean will mute much of warming.(7)
Precipitation Total annual precipitation amounts is not projected to change across the state. Rather the perception will come in shorter more intense rainy seasons, having more extreme precipitation events. Leading to short extreme winters and long hot and dry summers. Snow pack will continue to dissipate leading to more chances in droughts.(7)
Oregon Coast The Oregon Coast is set to have dramatic impacts from climate change as sea level will rise up to 8.2’ in certain areas by 2100. Helping to cause increased erosion, loss of beaches and loss of sediment to supply the beaches.(7) Ocean acidification from the oceans absorption of atmospheric CO2 will have dramatic effects on the ecosystem, having mass reductions in shellfish and sea life.(3) Similarly the warming oceans will have greater occurrence of Marine Heat Waves, having impacts on local climate and mass reduction in phytoplankton, further reducing sea life.(3)
Willamette Valley The Willamette Valley will exhibit many of the same impacts of the rest of state from a warming climate. More extreme fire events are expected across the Valley and the Eastern Oregon. The warming climate will prolong the growing seam by 2 months by 2050, but will also increase the risk of invasive and pests damaging crops. As snow pack decreases and more inconsistencies in annual precipitation, droughts and water shortages are expected putting further stress on agricultures increased. As well as straining timber production as trees become more stressed in the hotter and drier climate.(7)
Economic impacts The economic impacts of climate change will be felt across many of Oregon’s most important industries, from over a $1 billion annual losses in the fishing from decline fisheries, to $124 million annually in snow recreation from decreased snow pack and shorter winters. $37 million alone is expected to be spent on air conditioning annually as longer, hotter, and a larger population try to cool their businesses and homes.(2) The greater risk of hotter and larger fires will have a dramatic effect on the timber industry as projections indicated $700 million will be spent annually in fire suppression and upwards of $3 billion could be lost annually by 2080 in timberland. Dealing critical blows to one of the states largest industries.(2)

Strategies
House Bill 2020
Listed below are various strategies from different state actors on measures that should One of the states strategies in combating global warming is a proposed cap and trade bill. The bill would cap the amount of annual emissions Oregon will emit each be taken to help mitigate and adapt to a changing climate. year. Letting businesses buy permits for certain amount of emissions they can let off. Generating funds to improve infrastructure and support renewable adoption. The Basic guiding principles according to goals are to reduce emissions by 45% by 2030 and 80% decarbonization by 2050. With estimations that economic outcome of the bill will increase the GDP by 2.5% and ODFW: creations of 50,000 jobs. (5) The Oregon Department of Fish and Wildlife have outlined some basic building principles to aid in mitigation and adaptation measures. First is the maintenance and restoration of key ecosystem processes. Next, we need establish a stronger interconnected network Oregon Conservation Strategy of lands and waters that support fish and wildlife adaptation. Third, there needs to be Goals and action steps greater acknowledgment and evaluation of the risks of proposed management actions The Oregon Conservation Strategy outlines two major goals and 3 action steps that in the context of anticipated climate conditions. Lastly, there is a need to coordinate can be taken for each goal that agencies can take to achieve the goals. across political and jurisdictional boundaries in order for in order to create a an effective multidisciplinary approach. (8) Goal 1 is to use the best available science, technology, and management tools to determine the vulnerability of species and habitats to climate change at a landscape Oregon’s Climate Change Adaptation scale. Action 1.1 is work with partners to increase information on climate change vulnerability of habitats and species. Action 1.2 is support long-term research on climate Framework trends and ecosystem responses. Action 1.3 is develop and implement monitoring and Four key actions to boost effectiveness: evaluation techniques for vulnerable Strategy Species and Strategy Habitats. Goal 2 Is to identify, prioritize, and implement conservation strategies to mitigate Oregon’s Climate Change Adaptation Framework outlines 4 actions people can take to improve the effectiveness of actions taken by various actors. First is to establish a the negative impacts of climate change on fish, wildlife, and habitats. Action 2.1 states to governance structure comprised of state agency leaders empowered to set direction incorporate currently available climate change information into management plans for and allocate resources. Next they state to encourage a culture of inter-agency species and habitats. Focus on strategies that are robust to a range of potential future collaboration by building an information sharing and coordination platform so that climates and that maintain or restore key ecosystem functions and processes. Action State leadership and staff can draw from the same vetted data and information and 2.2 encourages agencies to minimize other threats. Action 2.3 is develop regional and can easily communicate across agencies to develop coordinated responses to climate local partnerships to coordinate responses to climate change across political, cultural, change. Third, different actors need to prioritize and involve most-affected communities and jurisdictional boundaries. (8) to ensure investments are targeted where they are needed. Lastly, agencies need to integrate climate change adaptation into agency work -- into our missions, authorities, Implications programs, plans and budget requests. (6) Concise and widespread reform is needed to stop and sequester greenhouse gas emissions, arguably the top priority of adaptation and mitigation measures. Models vary in the severity of impacts, but the impacts will be dramatic in all cases if nothing is done. The cost to act may be high to shift our infrastructure over, but the costs will be higher if little to nothing is done. To increase effectiveness of such measures, diverse and multidisciplinary actions need to be implemented. Lastly, our designs need to do more than the bare minimum of what current regulations require, because the regulations in place are not substantial enough to provide the change we need to sequester more carbon from the atmosphere. The strategies outlined here demonstrate that mush of the advice being given to different state actors is broad and gives a lot of room for interpretation. Also, is there any way to hold different state actors accountable for their efforts or lack there of?

Oregon’s Renewable Energy Portfolio and Potential - Amanda Craig and Carmela Sambo
Research question • What is the state’s renewable energy goals, its renewable energy portfolio and the Green New Deal’s Goal by 2050 and 2100? • What are the renewable energy potentials for solar and wind energy across the state and where are the existing and planned locations for solar energy and wind energy farms?
Solar and wind in the Green New Deal The Green New Deal proposes net-zero global emissions by 2050. It also suggests to prevent global warming to no more than 2.7 degrees Fahrenheit by 2100.

Oregon ranks 33rd in the country for energy production—and seventh in the country for total renewable energy production. Between 2008 and 2017, the average levelized cost of wind energy dropped by 75 percent (See Figure 3.12).

Implications Challenges for solar and wind energy planning
Potential for renewable wind energy Existing and planned wind energy Oregon’s wind energy industry has developed mainly on the Columbia River Plateau in north central Oregon. Wind farms have also cropped up in eastern Oregon near Milton-Freewater and North Powder. In 2018, wind power capacity has reached 3,383 MW; 44 operating facilities, 1 spans Oregon and the Washington state line; 2,147 MW of additional capacity proposed, approved, or under review. Sites range from 1.6 to 300 MW; 13 largest facilities makeup 69% of total capacity; 15 facilities, representing 590 MW, came online in 2009. There are currently no offshore wind projects, however there are several feasibility studies along the Oregon Coast. 17
• Intermittent resources, peak outputs occur seasonally and daily. Utilities need to meet customer demands as well as declining values for the energy when demands are low. • Financially viability, facilities should be sited near transmission lines to minimize the cost.This limits the locations in Oregon where energy generation development can occur. • Lack of Education and Outreach on renewable energy and associated initiatives. • Land Use Planning, financial, regulatory and legal barriers with current structures in Oregon. • Environmental impacts, construction and use of these facilities stressors on species and environment.
Solar Energy Land Footprint in Oregon
Oregon’s population is projected to increase from it’s current amount, 4,301,089, to 5,588,500 in 2050 and then to 7,817,142 in 2100. With this growth in population we can assume there will be a growth in energy consumption as well. With Oregon’s ambitious goals to lower carbon emissions and Oregon’s rising population, solar energy will be an important part of the future renewable energy grid.
- Carolyn Corl and Yeongseo Yu
Research question Given the projection of population growth, how many solar panels and land areas would be necessary to meet this energy need 100% by solar PVs by 2050 and 2100? What are the projected issues in urban/suburban/rural and natural areas?
Research method Atlas 2100 Project Calculations Leading to GIS Land Suitability Analysis By using the data provided by the McHarg Center’s 2100 Atlas for the Green New Deal, we were able to use Oregon’s projected population sizes as a ratio against the 100 million people that 2100 Project uses to calculate the amount of solar PVs required for 2050 and 2100. We also used current energy consumption trends in Oregon to predict future rises consumption, then, to find the area of land needed to support these needs, we used the area and energy output of the Topaz Solar Farm (Figure 2) to calculate how many times over the land area of the Topaz Solar Farm we would need to create one large area of solar farming. Now that we have the total land area needed to accommodate Oregon’s growing population’s energy demands, we are then able to use GIS data to determine suitable sites for the amount of land needed across the transect, which is reviewed in the Results section. Oregon is has goals to drastically reduce carbon emissions by switching over to renewable energy sources by 2050 from 62 million metric tons of CO2 to 14 million metric tons of CO2. Currently only 1.47% of Oregon’s energy comes from solar. Most of Oregon’s solar energy comes from large solar farms owned by utility companies located in rural Eastern Oregon’s desert (Figure 1). These farms contrast the many small, residential-scale solar cells installed on private property in more densely populated urban and suburban areas. With large portions of the state that may have the potential to support solar infrastructure in urban, suburban, rural and natural areas, it is important to locate possible sites across the complete transect and propose new strategies where solar energy may be possible.

Results Oregon’s future energy and land demands

It is expected that 2050 Energy demand would be 311.18TWh and 2100 energy demand would be 320.73TWh. Our assumption for the estimation is as follows: Although energy efficiency is expected to increase, we will likely develop new types of electronics or goods that require energy. Therefore, assuming those offset, we can just multiply population and energy consumption per capita. We estimated the future land demand, comparing the numbers of Topaz solar farm References in California, assuming the solar irradiance of Oregon would be 70% of California’s (National Renewable Energy Laboratory 2006 data); our research purpose was to (1) https://www.oregon.gov/energy/ energy-oregon/Pages/Greenhouse-Gasbriefly check the future land demands with energy demands.

Implications Installing solar PVs in all four land types will minimize impact on each one. Utilizing land that has already been disturbed, like cultivated land and low density urban areas offer close proximity to urban centers and opportunities for layering functionality and efficiency. Multifunctionality in agriculture could mean installing PVs among row crops or cultivating shade crops. Barren and shrubland have potential for large-scale solar farms but should not be fully developed to preserve habitat.

Research questions • Given the projection of population growth, how many wind turbines and how much land area would be necessary to 100% meet this energy need by 2050 and 2100? • What are the projected issues in urban, suburban, rural, and natural areas?
Background research Windmills were historically used to grind grain and pump water by generating mechanical energy. The earliest evidence of windmills was in the 1st century in Egypt, under Roman Empire1. Wind turbines, however, are complex, modern machines designed to harness energy from wind and convert it to electricity. The USA and Denmark currently lead in technological advancements of wind turbines 1. Here is a brief historical timeline: 1887 first built by Professor James Blyth at Anderson’s College in Scotland1 1900-1973 further developed and spread to compete with fossil fuel and centrally-generated electricity1 1973-Present advanced and widespread due to rising concerns over oil prices, fossil fuel depletion, energy security, and global warming 1974-1985 US Government funded NASA to develop utility-scale wind turbines1 1980-Present some US states offer tax rebates for wind power for utility electricity1
Wind turbine mechanics Wind energy is captured when blowing wind moves turbine blades around a rotor, which turns a shaft that spins an electricity-producing generator. Wind Energy Generation cleantechnica.com/2013/06/30/what-iswind-energy-wind-energy-101/

Oregon is 8th in nation with 12.1% annual electricity harnessed by wind power2 Currently, Oregon has 3,383 MW of wind capacity2, 44 operating facilities2 2,147 MW of additional capacity proposed, approved, or under review2,, and 1.6300 MW range in its sites2. Oregon’s 13 largest wind facilities create 69% of the total capacity2. The majority of its wind farms are located on Columbia River Plateau and in Eastern Oregon, and the majority are also privately-owned, utility-scale stands of References turbines. However, Vestas (wind turbine manufacturer) and Iberdrola Renovables (wind farm operator) have their national headquarters in Portland. (1) Vestergaard, J., L. Brandstrup, and R.

Innovative design of distributed solar energy generation Shipping Container Solar Systems - Hanna Ketterer
hassle of construction and assembly, and supplement solar energy generation with a wide range of amenities.
Planning Process Models of Different Companies • Moveit is based in Poland provides solar generators in either a 20’ shipping
container (70 m2 of solar panels) and 40’ shipping container (140 m2 of solar panels). Both have a sun tracking system that allows for constant alignment with the sun possible through sensors. Both sizes are available in two models, the SunBOX35A (automatic unfolding) and the SunBOX 42 (manual unfolding). (1)
• SPACE (Solar Powered Adaptive Containers for Everyone) is a collaboration between Adaptive containers and the University
Rationale
Why can this product be applied to Oregon? Shipping container solar systems are adaptable products and designs that can provide a wide range of multi-functional services for a community or site. They are favorable to quick turnaround time allowing for more rapid benefits to our urban environment. Models and companies discussed in this product case study can provide amenities that Oregon needs, specifically shelter, energy generation for “pop-up” urban events and agriculture irrigation.
Basic Information Conceptual Model
Shipping container based solar generators provide an innovative solution to easily transport solar energy generation to any location. The model, approached by many different companies, contains foldable solar panels that are stored for transport and when not in use in the shipping container itself. The shipping container is used as the carrier and support so the generators can be shipped anywhere in the world. The folding system and compact design allows the solar systems to be ready quickly upon arrival to the site and easily adapt to different location specific conditions. The project goals with these products include providing accessible power to a variety of locations, avoid
of Houston. Their design provides an 140 sq foot space inside the container with 20 solar panels on its rooftop. This model can provide up to 350 kWh of energy each month. In day-to-day function it is used as a workspace and transitions to selfsustained first response center in face of natural disaster. The first of the models are currently deployed in Houston for testing. (2)
Design Companies with Case Studies • Black Stump based in Melbourne, provides multiple solar powered shipping
container services including: freezers, water purification, and solar generators. Their client base ranges site power, commercial, defense, government, events, first responders, agriculture and aquaculture, and aid and development. Black Stump partnered with an agricultural community in Papua New Guinea to increase quantity and quality in the post-harvest/ pre-cooling process. Products including solar ice makers and solar chillers allowed the farmers to double their revenue compared to conventional diesel equipment. (3) References (1) Moveit Power.

• BoxPower,based in Grass Valley, CA, provides affordable containerized solar
solutions for residential, agricultural, community resilience and commercial clients. They partner with nonprofit and governmental agencies to provide solar generation to hard to reach communities. Their systems come in two models, a 20’ cargo container providing over 22kW and a 4’ x 8’ mini-box providing over 3.5kW.
Partnering with Mutual Aid Disaster Relief, Arecma, and Footprint Org, BoxPower provided solar generated power to communities in Puerto Rico after Hurricane Maria in 2017. The containers brought power to a community resilience center, health clinic and soup kitchen. In January of 2020 BoxPower returned to Puerto Rico to provide container solar generators to communities after a series of earthquakes that left another island wide black out. Working closer to home, BoxPower worked provided a Light Manufacturing Company in Concord, CA with solar plus battery storage. With this client they used their Energy Audit System Integration (EASI) service to recommend the optimal solar system at the least cost.
Evaluation Transecting Urban, Suburban and Rural Landscapes Due to the concept of combining solar panels with shipping containers and other amenities, it can be a very easily transferable model applicable to many densities and conditions. Shipping container solar generators can provide energy to informal settlements due to their no operation and maintenance cost. Additionally, since they are quickly deployable, they can used in rapid disaster relief movements. In the suburban context the solar generators can be used in commercial and industrial settings to start to offset the large quantities of land those industries take up. Lastly, in a rural setting solar generation can be used to power remote agricultural systems like irrigation and pre-cooling models. Within Oregon, shipping container solar generators can be used in transitional housing communities such as Opportunity Village, farmers markets and food truck blocks, yearly festivals, agricultural uses, and commercial/industrial use.

Impact BoxPower Pricing Model (4)
Social • These accessible models can provide social benefits such as a home or workspace that is completely off the grid. It can provide power to remote communities in post disaster relief efforts and as a community hub.
Environmental
• Not only are these designs providing off grid energy generation, they are also providing multi-functional “landscapes.” Pairing solar panels with amenities such as freezers or water purifiers takes away the need for that service to be taken up with References other land and energy.
Economic BoxPower Model (4)

BoxPower Puerto Rico Case Study (4)
• Site and project specific models can increase agricultural productivity and revenue for farmers. Once the up-front cost is taken care of, operation and maintenance costs are low to none. However, the up-front cost of these products might be inaccessible to certain communities that could benefit from them.

Renewable Energy on Existing Infrastructure
A Case Study on Solar Bike Paths in the Netherlands - Lexi Smaldone
Rationale
Why Solar Bike Paths Can Work in Oregon The state of Oregon has plans and regulations relevant to both climate action and bicycle infrastructure - there is no reason not to achieve both goals with one design. Oregon’s Climate Action Program, for example, aims to reduce statewide greenhouse gas emmissions to 80 percent below 1990 levels.1 While the state’s “Bike Bill” requires all new road projects to accomodate bicycling and pedestrain travel.2 Moreover, cycling is already popular in Oregon’s urban centers, particularly the cities of Eugene and Portland, and especially in the age of COVID-19.
Basic Information
Pilot Program in North Holland This project is less about enticing people to ride bicycles and more about combining solar energy with existing infrastructure. This project started as a 70-meter stretch of existing bike path in the North Holland province.3 This path is a two-way cycle-track in which one lane is paved with solar cells.4 When the pilot launched in 2014, it was the world’s first public road that included embedded solar cells.5 This 70-meter stretch of solar cells cost $3.7 million to install.5 Since its installation, 20 meters of solar panels were added to the bike path.6 The purpose of this pilot program was to test the viability of solar power production on road infrastructure.5 The program began the study by piloting with bicycle infrastructure because the vehicles are lighter, roadways cover less surface area, and, thus, are less likely to damage the panels than cars, trucks, and other vehicles. The total road surface in the Netherlands is also significantly larger than the area of rooftops suitable for solar installation.5

This pilot program was led by the Dutch government, who partnered with solar panel company SolaRoad and research group TNO.5 The initial pilot launched in 2014 and was generally a success. The project is currently in the second phase its planned exponential expansion.7 In 2016, an additional 20 meters were added to this 70-meter stretch in North Holland.6 This year, in 2020, two additional projects are expected to begin in the Utrecht province and near Maartensdijk, but are likely delayed due to the COVID-19 pandemic.7 Hopefully soon the project can move to the next phase of embedding solar panels into roadways. Each new addition uses lessons learned from the previous study and makes any needed improvements.4 So far, some issues that have been discovered are related to cost, efficiency, and durability. The 70-meter stretch of solar panels cost the same as installing solar panels on the roofs of 173 homes, for example.4 On top of being more expensive, these panels are also less efficient than those placed on rooftops References because they cannot be laid at an angle.5 Durability is an ongoing battle - the top layer (1) State of Oregon Carbon Policy Office. “Summary of Core Elements of of the solar element broke off during poor weather.4

Evaluation
Suitable in Urban Areas In Oregon, Portland and Eugene already have extensive bicycle infrastructure and plan to create more.2 The state of Oregon has plans and requirements for both climate action (i.e., reducing greenhouse gas emissions) and bike lanes, in which this application would work towards achieving both. The goal of this project was not to entice people to cycle more, but to apply solar energy to existing infrastructure with efficient land use. In Oregon, many people already do not need to be strongly enticed to ride bicycles. While it may be cheaper to install solar panels on roofs, that comes with its own costs. Homes in Oregon are often shaded by many nearby trees. Oregon views itself as a green state, and while solar panels are a green technology, our trees are culturally important in Oregon. Urban streets generally have less shade cast on them due to the regulated height of street trees. Portland has an extensive infrastructure for bikes already, providing ample opportunity for this application.9 In Eugene, the Riverbank Path as well as designated bike routes provide opportunities for implementing a pilot project with this excting technology.10 References (7) Bellini, Emiliano. “Construction Begins on Pilot Solar Bike Lane in the Netherlands.” pv magazine International, January 29, 2020. https://www.pv-magazine. com/2020/01/29/construction-begins-onpilot-solar-bike-lane-in-the-netherlands/.
Project Layout8
Impact
Somewhat Success In the first six months the SolaRoad project, the panels produced 3,000 kWh of electricity, which exceeded expectations.6 After one year, over 300,000 cyclists used the upgraded path, and enough energy was produced to power three homes for a full year.6 20 meters were added to the 70-meter stretch, and two more pilots will begin this year in other provinces of the Netherlands.7 Adjustments are being made before each installation. Besides the one break during the first month, the path is holding up just fine to the cycle traffic and weather.6 The next steps for the team are to figure out how to cut costs and, if possible, increase efficiency.

Reclaiming brownfields
Reclaiming Abandoned Mine Lands (AML) for Solar - Caroline Fitzpatrick
Rationale
Opportunity for Oregon There is a large concentration of abandoned mine lands in Oregon. The AML program, headed by the BLM and Forest Service, sites there to be between 1625 and 3250 abandoned hard rock mines. Utilizing contaminated sites for renewable energy allow for large scale development that does not disrupt current uses, it leaves other sensitive areas, such as agricultural land and forested land, protected, the land is relatively flat, lacks forest cover, potentially has preexisting access roads and transmission lines, and is generally not hospitable for reforestation1.
case of the flooded mines that have turned into lakes, floatovoltaics are implemented. These lakes often have a low pH are are generally not suitable for habitat. In addition, the water cools the solar panels, helping them work more efficiently. The lack of surrounding dirt and dust allows the panels to stay clean longer3.
Planning Process
Public and private partnerships The planning process relies on both policy and investment of private interest. The Nature Conservancy aims to develop land previously impacted by economic development, such as mines, rather than developing on intact greenfields. The Nature Conservancy created a plan with the Nevada Mining Association titled “Mining the Sun,” they sited that renewable energy was not listed among state regulations as a possible postproduction use for mine lands Adding this possibility to the list eliminated a gray areas for solar developers4. The BLM and Forest Service have an AML program that was initiated in 1997. Addressing the environemntal impacts of abandoned mines on both BLM and forest Service land is part of their duty. Addrsesing water quality concerns is the main objective of their program mission. Therefore, habitat restoration has been a priority5. Co-locating renewable energy with their restoration efforts could be a very powerful partnership.

SunMine Kimbereley,BC SunMIne solar farm is BC’s largest solar project, it was implemented in 2015. The solar panels are situated on the south facing slope of an abandoned coal mine. The design included 4,032 solar cell modules situated on 96 solar trackers. The abandoned mine is situated high up in the mounatins recieving around 300 days of sunlight per year6. The solar farm is able to produce enough energy to meet the demand of 200 households. The economic impact on the city of Kimberely has been positive and there is a desire for expansion of the project6.

Impact
Floating solar farm Anhui Province, China The Anhui province of China holds the largest floating solar farm. It is situated on a lake that formed over a collapsed coal mine which was flooding by precipitation. 166,000 panels were installed on flotation devices. These panels are capable of generating 40 MW of energy to meet the demand of 15,000 homes3.
The case studies outlined in this report exemplifiy the potential of large scale renewable production possible on abandoned mine lands. The expanse of open land available at these sites is a great opportunity. Depending on the site, energy could be generated for up to 15,000 homes, as reprsented by the floating solar farm in the Anhui province. The SunMine in Kimberely, BC represents a successul economic outcome. The City of Kimberely directly benefits from the revenue of the SunMine. The project is community owned creating pride and ownership within the community. With the inclusion of more incentives for smaller productions, these types of operations could increase7. The image below illustrates the extent of abandoned mine lands on National Forest and BLM land. It is clear that significant land area exists in the state of Oregon for a solar mine field to be considered.
The Challenge of Reclaiming AMLs The cost of reclaiming a single abandoned “A boat navigates the Huainan solar farm.” https://time.com/china-massive-floating-solar-field/ mine may range from tens of thousands of dollars to tens of millions of Utilizing contaminated land, such as abandoned mine lands, provides adollars unique depending on size, location, opportunity for renewable development.

Ecological Energy Network A FABRICations Project
Design
Project Goals
- Kris Parr
Rationale
Retrofitting Existing Energy Infrastructure Electric energy corridors are a staple of the landscape. When designing for resiliency, creating dynamic and multifaceted landscapes in these unused corridors deepens function and ecosystem integration. Oregon can benefit from projects like the EEN by hybridizing infrastructure for human use and wildlife habitat. Yet, being mindful of fuel loads under these power-lines is an important factor when approaching the wildfire season of the Pacific Northwest.
Basic Information
Part of a wider analysis on the Urban Metabolism of Rotterdam, Netherlands The Housing Options of 2005 prohibited “prolonged stay” (14-18 hrs) under high voltage lines, restricting a majority of human programs. “Sensitive locations” include schools, childcare facilities, hospitals and other populations that are sensitive to environmental conditions. In fact, especially high voltage corridors include a 50-76m function free zone.
• Creating an urban ecological corridor revitalizing prolonged stay areas under high voltage areas; thus bringing nature into the city. • Connect the missing links in the Netherlands’ National Ecological Networks (EHS) • Nature in electric corridors to become a temporary stay destination for leisure activities
Ecology is a non-sensitive program, and therefore has potential for unlimited use in these restricted areas. Utilizing these programmatic “dead zones” by creating habitat niches allows a multifunctional and dynamic landscape.
Planning Process
Overlaying Strategic Systems This project overlays existing ecological habitat zones with the Netherlands’ national power grid. “If realized, the Ecological Energy Network creates the largest National Park of the Netherlands, larger than the Oosterschelde (370 km²) and Veluwe (52 km²) combined” Designers in FABRICations created typological studies of electric corridors as they would transect urban, suburban and rural landscapes. These spatial studies offer insight and easily reproducible typologies for other areas. 30

Impact
Resilience in Redundancy Electric corridors offer opportunity to creating a multi-faceted landscape. Striking a balance between habitat creation and responsible fuel loads for electric corridors would simultaneously benefit native wildlife while limiting devastation in wildfire season. Similar projects are already underway in Eugene natural areas, such as the Howard Burford/ Mt. Pisgah Recreational Areas. In addition, researching collocation of these existing corridors with sheep pasture habitat would benefit the agricultural nature of the Willamette Valley.
Evaluation
A Transferable Framework Many trails and open areas in the Willamette Valley are already bi-sected or tangential to power-lines. In addition, Eugene in particular prioritizes the interconnection of native ecologies, including wetlands, uplands and the urban forests.

Integrated Vegetation Management - Taylor Bowden
Rationale
Why can this case be applied to Oregon? Powerline land is vital to our electrical power transmission systems, and is unlikely to be going anywhere, but and management under power lines can be improved to support ecosystem diversity. Existing powerline management techniques have been known to degrade landscapes and ecological connectivity.3 Prairie habitats are threatened in the Willamette Valley, and powerline infrastructure presents prairie restoration opportunities. Loss of these habitats have resulted in a loss of biodiversity. 1, 2
Planning Process
Stakeholders, Issues, and Timeline Stakeholders include: -Transmission System Operators - Landowners -Private landowners -Utility managers -The public -Wildlife The main roadblock to adopting these strategies lies in making IVM management a priority to people. Issues to adapt to this new management involves stakeholder participation, perception, policy restrictions, resources, and knowledge. 1 These management strategies could be phased in slowly, or used independently from each other in order to make them easier to integrate into existing management techniques. New corridors should immediately implement IVM strategies after construction. Initial implementations of IVM strategies need to be carefully managed until the vegetation successfully establishes, and can better compete with invasive species. There will still need to be regular cleaning and management of trees and invasive species incursion. 1

Basic Information
LIFE- Elia Project: European Green Electricity Corridors
5 Strategies 1. Selective tree cutting:
The goal of integrated vegetation management (IVM) is to turn powerline lands into green corridors and green infrastructure through environmentally sensitive management techniques.
Restore forest edges by creating ecotones. This involves planting management edges with shrub and grassland habitats, softening the gradient of forest to prairie, and allowing for better ecological connectivity.
The LIFE- Elia Project is the application of IVM strategies to European Transmission System Operators (TSOs). These management strategies are suggested for use across Europe’s electric energy corridors and have already been applied to over 30 sites. LIFE- Elia Projects replace unsustainable management techniques like herbicides and slashing, which keep powerline corridors safe, for ecological restoration of grassland, wetland, and scrubland habitats that meet safety guidelines 2.
2. Restoring grasslands: Grasslands offer a high diversity of plant, invertebrate, bird, and small mammal habitats.

3. Restoring scrubland and bogs: Woody scrubland and bogs offer specialized habitats that may help increase biosystem diversity. Designing these habitat interventions based on the local ecosystem is more considerate of animal lifecycles.
4. Adding ponds/ vernal pools: Digging small water bodies along the corridor can seasonally support sensitive aquatic species where the topography and ecosystem are appropriate.
5.Controlling invasive plants: Remo=ve and prevent the regrowth of invasives as native plants establish. Managing invasive plants in the early stages of restoration will help block future invasive growth once the native herbaceous plants have colonized the disturbed soils.
Evaluation
IVM is Widely Applicable IVM application is suitable to retrofit existing electric energy corridors and new infrastructure in Oregon. IVM will help mitigate environmental impacts and increase ecological connectivity in urban, suburban, rural, and natural areas. Maintenance of these energy corridors must occur regardless, so these strategies could offer a standard of symbiotic managament practices. 1, 3 A more intentionally designed corridor may serve as prime open space for recreation with the addition of trails in urban and suburban areas; as long as active powerlines are out of reach of people and carefully maintained, the risk of danger to people is low. There are many examples of sites across the US which have already utilized powerline corridors space for human recreation. 4 IVM strategies may help planners decide where to place new energy corridors to correspond with prairie habitats or potential prairie restoration areas using tools like GIS and AHP. Birds flying into powerlines is a risk and hazard that all powerlines must consider, and changes to these bird risks and impacts after IVM need more evaluation. Fire risk by increasing fuels should also be considered in management.6, 5
Impact
Improve Existing and Future Infrastructure Intergrated Vegetation Management strategies increase biodiversity and viable habitat for wildlife along energy corridors by reconnecting habitats and creating edge conditions.

IVMs replaces problematic management methods like slashing and herbicide which degrade the landscape and harm wildlife. More cost/analysis research it may also reveal to be a more efficient use of resources over time by reducing the speed of invasive growth. 7, 1, 2 Implementing IVM strategies will require participation from a variety of stakeholders, and a rehaul of common enegery corridor management practices.1 The issues of implementation would be resolved if fit within a Green New Deal where renewable energy corridors have the labor, resources, and support and to implement these environmentally friendly management techniques. 7

Nordergründe Aquaculture: Offshore Agrowind Solutions to Food Security -Aaron Woolverton
Rationale
Applicability to Oregon There is a great need to establish aquacultural production throughout the United States of America. Although the industry is considered to be well established, the FAO expresses the country’s need to expand its current operations. Interestingly, the USA imports approximately 80% of its seafood and farms a very small percentage; ultimately, the USA depends on both its capture and its imports.1 See Figure 1.1 for a graphic representation of the Country’s dependence on capture and its need for farmed seafood. Meanwhile there is a growing need for wind energy in Oregon, and one study provided by the National Renewable Energy Lab realized the economic viability of establishing offshore, floating wind turbines. One of their priority zones includes a site off the shores of Coos Bay, Oregon.2 Coos Bay, one of the hubs for aquacutlural production, should utilize their infrastructure and consider collocating offshore aquaculture with this wind energy scenario for sustainable economic gains.
80 Sq. Kilometers, or 19,800 Acres. The conditions of this sea are somewhat similar in temperature and wind/wave activity to Oregon’s offshore conditions - however, the Nordergründe is located in 30 meter deep water. Ultimately, the wind farm produces 111 Megawatt System which powers about 100,00 homes in Germany. The offshore aquaculture plot is about 120 acres and produces an economically viable yield. 3
Planning Process
Accessing Stakeholders and Ownership Throughout this case study, there remained several quotations regarding ownership, rights of way, the definition of international waters, and the questions surrounding ecosystem impact within such a maverick proposal. Buck et al. provide insight on their questions with the following quote: At present, there are few frameworks that facilitate integrated strategic and comprehensive planning in relation to all activities taking place in marine areas. In the end, this was a pilot study that didn’t necessarily need approval for a major retrofit - however, the researchers did go about a planning process, public perception analysis, and ecosystem / environmental experiment to chose the right spot for this study. 4 The preliminary planning process included mapping existing wind farms, their proximity to coastal towns, and their accessibility for offshore aquaculture. The researchers went on to assess ownership and right of way between stakeholders, major shipping channels, and government agencies. Using maps provided by miscellaneous studies, References the researchers performed ecosystem experiments ton “ideal” areas to determine the (1) FAO Fisheries & Aquaculture—National best location for Spat reproduction and spawning of bivalves naturally.

Prototypes, Experiments, and Options
Figure 1.1; Data by FAO
Basic Information This feasibility study aimed to ascertain the economic feasibility of an offshore marine aquaculture structure for breeding of marine organisms (bivalves) in tandem with renewable energy systems. The Nordergründe wind farm is located approximately 17km North of Bremerhaven, Germany in the North Sea. This wind farm, although considered small, is made up of 18 wind turbines and encompasses an area of about 34
The overall goal of this project was to understand the feasibility of utilizing offshore wind farm infrastructure as a means to produce aquatic organisms for consumption. As seen in both figure 2.1 and 2.2 below, the design incorporated several elements and options related to current practices in aquacultural systems. More specifically, these systems include traditional long-line farming, cage farming, and hanging systems, such as oyster lanterns. All together, the designers developed and tested these options through a series of prototypes. Another goal to this project was to assess the feasibility of a spat collector system. This system would reduce resources and subsequent GHG emissions between harvesting spat in typical intensive harvesting processes and the transportation to the wind farm via boat. There were positive results from this natural spat collector, and this invention would greatly reduce resource requirements. The design process between modeling, simulation, and predictive futures allowed the researchers to paint a full picture if this project was to proceed. Figures 3.1 and 3.2

reveal the design options related to the production of aquaculture and how those systems may work in tandem with the existing wind turbines of Nordergründe. As an add-on to the preliminary goals, the designers decided to consider how this system may enhance ecological diversity. This approach considers both the diversification of aquacultural products, such as bivalve production with fish culture through fish pins. The study also considered establishing artificial reefs (Figure 3.3) at the foundation of the wind farms by incorporating several technologies to enhance reef growth and ensure its health through monitoring devices.
Evaluation
An Economically Feasible Solution Ultimately, through several studies, Buck et al. conclude that the incorporation of aquaculture techniques onto existing wind farming infrastructure is incredibly economically advantageous. The economic study section of their report provides a list of helpful takeaways: With current market values a single long-line could have a production value of 16,750 € (1,000 € × 16.75 metric tons) or $18,143.00 per growing season. A single mussel plot (120 Acres) would provide approximately 1,190,000 € (1,000 € × 1190 metric tons) or $1,288,950.00 per growing season. 6
Figure 2.1; Buck et al.
Figure 2.2; Buck et al.
It is important to note that the German Bight sees 2 growing seasons throughout a year. So these values should be doubled. 7 The team also explored some various concerns regarding operations and management of the aquacultural system. They propose that, if no private entity were to operate the farm, maintenance crews may be trained to mange this system - offering another layer of work to the operation managers at the wind farm. Overall, this report’s conclusion provides an important insight to the advantages of multimodal land-use. It will be important to know how these offshore aquacultural systems impact the local ecosystem and whether or not these conceptual reef structures come to fruition.

If Oregon was to develop an offshore wind farm in the pacific, the principles and ideas presented in this study could have a profound impact on the state’s economy and resilience in terms of sustainable food production. Even if wind farms were applied inshore - within bays like Tilamook and Coos - there is a vast amount of existing References aquaculture infrastructure that may be adapted to work with coastal wind farms. Of course, we must consider limitations to these two options. Option 1, which would (6) Buck, B. H. (2007).

Co-locating Solar with Sheep A Case Study from Cornell University - Liz Koonce
Planning Process Prep & Procedures
Sheep were grazed between May and November 2018 to obtain agronomic and economic data, as well as to gather knowledge of the feasibility of grazing sheep on solar sites (Kochendoerfer et al., 2018). A survey was sent to three entities; (1) sheep farmers grazing solar sites; (2) landscapers maintaining solar sites; and (3) solar site managers. The survey collected data on the economics of solar sites across New York state and the Eastern United States to gain a better understanding of co-located agrivoltaic systems and solar grazing.
Design
Site Specifics A 22-acre solar site was divided into 4 plots. 56 sheep were used, with a grazing density of 3-7 sheep per acre (average 2.5 sheep per acre). Plots were rotated and rested to ensure that pastures were not overgrazed. At each rotation pastures were surveyed for vegetative quality and nutritive value for sheep.

How does this apply to Oregon? Oregon is ranked 9th in the country for number of domestic sheep in the livestock industry, with 195,000 head of sheep and lambs grazing annually. This is 4.74% of all domestic sheep in the United States (Census of Agriculture, 2017). Solar energy is measured in kilowatts per square meter per day (kw/m^2/day)/ Annual data for direct solar irradiance shows Oregon to have aboveaverage potential for solar power (US Annual Solar DNI, 2018).
Agricultural, Economic, and Environmental Potential Sheep & Solar
Located in Aurora, NY, this case study focused on large-scale solar using multi-acre sites of ground-mounted solar panels. For these types of large solar installations, 5-8 acres of panels are required per megawatt (M) output. Operation of solar sites in vital summer months with most hours of sunlight requires vegetation to be kept from shading the panels. Traditional methods for keeping panels clear include mowing and string trimming, which are labor intensive maintenance regimes on sites that can be remote and/or hilly. 36
Left: Site plots Bottom: Panel dimensions
Evaluation The study found that solar sites grazed by sheep required no mowing or string trimming for the entire season, from May 1 to Nov 5. Sheep were healthy with positive body scores and low parasite loads. Compared to traditional vegetation management on site, sheep grazing required 2.5 times fewer labor hours. In the survey sent out to sheep farmers on the East coast, 14 responded, and reported 3,503 acres of utility solar being grazed by sheep, with a density of 3-4 sheep per acre. These farmers cited yearly or multi-year contracts with solar utility companies, which were mutually beneficial.
Sheep graze amongst solar panels.
Impact
Why does it matter? Grazing sheep on solar sites is a cost-effective method to control onsite vegetation and prevent panel shading which provides twice the utility on the same amount of land; an important factor as the United States switches towards renewable energies and the large footprints associated with these landscapes. Co-location also preserves of agricultural land while still increasing renewable energy landscapes, whith direct benefits to small-scale sheep farmers. The approach is eco-friendly, without the use of herbicides in the control of vegetation. Overall, co-location of sheep on solar sites is a profitable, environmentally-friendly, and climate-resilient agrivoltaic strategy.
Grazing sheep on solar sites is cost-effective

Rationale
Save land and connect to existing infrastructure Floating Photovoltaic (FPVs) panels do well in reservoirs and in relatively temperate areas that are not exposed to icy, turbulent, and high salinity bodies of water and would perform well in key areas in Oregon.1 In Oregon, where land suitability is low for energy generation due to agricultural, conservation, and other purposes, open man-made bodies of water can be used for solar panel projects. In Oregon there are hydroelectric plants where the panels can be installed and connected to the energy grid near urban areas, similar to the Yamakura Dam solar plant.
Basic Information
The largest of its kind at the time The Yamakura Dam FPV project was Japan’s largest solar plant in 2018 producing 13.7 megawatt (MS).2 It is located on the Yamakura Dam reservoir in Ichihara, Chiba Prefecture2. The solar power plant covers 180,000m2 of surface area (the equivalent of 18 soccer fields) with 50,904 270-watt Kyocera modules of 60 cells).2+3 The structure covers 32% of the water’s surface4. The assemblaged panels are anchored at the bottom of the pond and are designed to meet a maximum depth of 15.3 meters.4 The floating photovoltaics produce an estimated 17,170 megawatt hours (MWh) per year which is enough electricity to power 4,970 local households2. It requires roughly three acres of water surface to produce one Megawatt.1 The plant offsets approximately 7,411 tons of carbon dioxide emissions every year that it is operation, equal to 19,000 barrels of oil.3
Planning Process
A joint collaboration for environmental good The process of building the Yamakura floating solar plant began in October of 2014, operations started in 2016, and the panels were installed on March 5th, 2018 in the south-east area of Tokyo, Japan.5 Kyocera TCL Solar is a joint venture between the Kyocera Corporation and Tokyo Century Corporation and was established in 2012 to promote large-scale solar projects.2 At the start of the planning process of the Yamakura floating solar plant, this was set to be the largest floating solar power plant in terms of energy generation in the world.3 This project was Kyocera TCL Solar’s fourth floating plant.3 Ciel et Terre supervised the engineering of the floating photovoltaic system and manufactured the floating Hydrelio® system in Japan.4 To celebrate the opening of the installation, a completion ceremony was held with Kensaku Morita, the References Governor of Chiba Prefecture.2 The plant is installed on the surface of the reservoir (1) https://www.inverse.com/artiand is managed by the waterworks bureau of Chiba Prefecture for industrial use.2 The cle/49520-floating-solar-farms-coming-us generated power is sold to TEPCO Energy Partner, Incorporated.2 This project was (2) KYOCERA TCL Solar begins operation originally started by the Public Enterprises Agency of Chiba Prefecture working to help of Japan’s largest 13.7MW Floating Solar companies reduce environmental degradation.2 Floatovoltaics produced by Kyocera Power Plant.

Design
Easy to install and long-lasting Floating installations require less heavy equipment to install such as the use of heavy equipment to clear trees for installations on land, for example.1 The panels are made from the same material as ground installations and are expected to last for approximately thirty years.1 They have a link resistance of 3,000 DaN (3t) and can withstand windspeeds up to 118 mph and water level changes of up to twenty feet.5 On September 11th, 2019, a the Faxai typhoon swept through with winds of 120 miles per hour and loosened the modules resulting in a fire.8 This was difficult to contain as the firefighters were dealing with fire, water and electricity simultaneously.8

Concept Diagram
After doing the solar, wind, and radation analysis, I divided the buildings into four facades to improve with the combination of typologies such as combining balconies, covering with moss panels, adding photovoltaics, and adding a skyway and rope moss installation.
Perspective To make a hyperfunctional urban space, I first proposed adding residential spaces to the upper part of the building. In area 2 of the facade, I added balconies to give people the opportunity to enjoy the environment outside. Underneath the balconies that receive little sunlight, I have added moss panels for additional green and air filtration. Where there is less solar radiation, I proposed adding moss panels to the vertical face of the building. The west side of the building offers a unique opportunity for its close placement to the building beside it. I wanted to connect the building with a skyway for protection during unfavorable weather conditions. I also propose a woven moss rope installation above to further connect the building and give people an enjoyable and shaded experience of walking through the skyway. On to p of the building which receives the most sunlight, I propose including photovoltaics which can serve the immediate community and serve as an alternative to current energy sources. I also placed a pavilion with moss and photovoltaic panels for when shade or protection is needed. The roof is accessible for people to enjoy their immediate space and enjoy the beautiful surroundings of downtown Portland.

Buildings are responsible for half of all sector- based emissioBuildings are responsible for half of all sectorbased emissions in Multnomah County. If these spaces were to be retrofitted with renewable energy resources, this would cause a massive decrease in carbon emissions. Programs like Solar Now! Solar Within Reach, and Solar Forward show that the community has massive support for solar. These nonprofit photovoltaic organizations work towards building demand as well as making solar more accessible through the reduction of costs of permitting, zoning, land- use practices, and installation.

Following the Downtown Portland location and the using the other urban groups reformed water way as a passageway, I chose a different project area in the North West of Portland that I like to call the Broadway Block. The carbon emissions are quite impactful in this area as this block houses the Greyhound Bus Station- building number 4. Another draw to this site was the Transitions Project Headquarters – building number 7; next to the final site of the 5 hundred thousand square foot post office.

A large benefit to the northwest Portland site was because the Transition Projects’ headquarters is located within the proximity. Transitions Projects is an agency that offers currently houseless and people within venerable communities resources through social services including case workers, healthcare, mentorship and housing. There are currently 19 different locations to seek housing; emergency shelters, severe weather shelters, short term residential programs, project centers and apartments. One of the apartment complexes, Argyle Gardens, is a high- efficiency affordable housing model. The modular style creates a deeply affordable housing project that will be in operation for long terms. The Post Post Office Oasis is designed as a community space making this site a large outdoor recreational for all of the patrons of the Transition Projects

PHASE 3- Add Greenery on Main USPS Structure
In 2019, a 1/3 hectare land near Lake Constance, Germany was set aside as a pilot site to research the synergy between photovoltaics and agriculture also known as, agrophotovoltaics. On site, the photovoltaics were placed 5 meters high to allow for livestock and machinery to pass underneath. Below the panels, winter wheat, potatoes, clover, and celery were planted. Compared to the reference field, the agrophotovoltaic field experienced 30% less solar radiation due to the partial shading of the photovoltaic panels. The panels impacted the distribution of precipitation as well as aided in maintain soil moisture. These changes increased the agricultural outcome; celery yield increased by 12%, winter wheat and potatoes yield increased by 3%, while the outlier, clover, decreased by 8%. Overall, the land use efficiency increased is estimated to have improved 160% through photovoltaic and agricultural output per hectare.

This diagram shows the multifunctionality of the layering of typologies. Each of those green spaces represents one acre. With one program per acre, there is a possibility of 100% output. By making the acre dual purpose, there is now a 200% possibility of output which is much greater than 100%. It is two for the price of one.
47
The early phasing of this project is to happen while the post office is still in use. Through the installation of photovoltaics over the parking lot and USPS building, business can continue as usual with the added benefits of having renewable energy and shade for the parking lots. When society has progressed past the need for postal services, the site will be left with 23 large (208’ x 36’) and 12 small (105’ x 36’) solar panels and a green roof on the main building. Once the site is no longer in as frequent usage, the space can be further transformed through the addition of green space underneath the photovoltaics which be utilized for gathering and gardening by patrons of the Transition Projects.
Agrophotovoltaic output The impact of the photovoltaic energy alone could save close approximately $1.8 million. This is based off of an average of 6 hours of sun per day and 7.051¢. price for kWH from Portland General Electric. All of the solar panels would produce approximately 250,000 kWh or 850 mmbtu, classifying this site as medium. With the greenery planted below covering most of the concrete surfacing, there will be a reduction in solar radiation on site as well as the added benefit of aiding in storm water management through the plant palettes chosen root system.

Post covid waterfront
Group Goal:
- Alison Grover, Carmela Sambo, Isabela Ospina, Su Li
In creating a post covid waterfront for Portland, Oregon we will integrate social urban nodes, sustainable transportation, the urban FEW nexus, and the water’s edge to enhance physical connections, social equity, and recreational amenities. We will incorporate energy generation, transfer, collection, and storage with each of our typologies. Our interventi ons address issues specific to urban riverfronts, mobility, accessibility, and equity while building open space to accommodate individuals and smaller group sizes. Portland’s western waterfront is an ideal site to achieve our team goal because of its solar potential, existing public transportation, high car/bike/pedestrian traffic, social events, proximity to vulnerable populations, and its adjacency to the Willamette river.

Urban FEW Nexus
Nidolères Estate Agrivoltaic System:
- Isabela Ospina
Individual goal Within Portland’s West Bank waterfront between Burnside Bridge and Morrison Bridge, is where the Urban FEW Nexus typology will propose a set of designs that support the Urban Core: Post COVID Waterfront. Here, a variety of programs respond not only to a post COVID society but also to the Green New Deal by educating the public through innovative design. This typology in particular focuses on the Food, Energy, Water (FEW) nexus by incorporating agri-voltaics to best utilize sunlight for food and energy, and a water catchment and filtering system that uses the overhead bridge runoff and rainwater to water the adjacent urban agriculture. Coexisting, is a small-scale respite shelter for houseless people under the Morrison Bridge, since the bridge brings a huge asset for shelter. The energy, food, and water can be harvested for this shelter to create power, running water, and food supply with surplus to sell at the Saturday market. Where the waterfront park meets the road, a green buffer can remain to buffer the loud ambience of downtown from the tranquil waterfront gardens. On the northern part of this site, there is a separate garden that can be used predominantly for educational purposes, with chaperones and community members to teach kids, families and anyone interested how to garden.

Water’s Edge - Carmela Sambo
Individual goal The water’s edge is reimagined to accomplish 3 goals: 1) Energize, 2) Entertain, and 3) Engage. Energize - the site is designed to energize local, small businesses and street lighting by utilizing rrenewable energy sources such as solar panels and smart turbines. Entertain - the site promotes healthy and accessible spaces by providing a canoe launch, a tide pool, and multiple viewing platforms that can also function as a helicopter pad for emergency preparedness. Engage - the site seeks to educate the community and its leaders through outdoor classrooms and seating, which are designed for social distancing practices.
Site Analysis Site Conditions
1-BIG + Field Operations - North Brooklyn Waterfront Design 2-Smart Turbine 3-Club Med Finolhu Villas, Maldives
Background research and precedent
The site is located between the Hawthorne Bridge and Marina, as depicted in the above graphic. It is also next to a block consisting of various restaurants, businesses, a hotel and condo. This block could serve as potential energy collection from the smart turbine and solar panels in the site design. The site was chosen due to its proximity and public access to the river. It is also adjacent to an existing bicycle and pedestrian path, which allows easy access from passersby, tourists, and residents. It is also next to an open space park which does not obstruct views from the beach and acts as an extension to promote health and equity to the area. Other than providing areas to lounge near the river, the site lacks multifunctional spaces, direct relationship to the river, and interactive spaces.
Design Proposal
Design with Energy
Design concept
Design inspiration for the water’s edge derived form the North Brooklyn Waterfront Master Plan design by BIG + Field Operations (1). This waterfront design showcases multifunctional spaces for learning and provides areas for an array of water activities. Being that the site is along the river, proper renewable energy sources include a Smart Turbine and solar panels. The Smart Turbine (2) is a hydro-powered generator that is capable of producing up to 5000 W of clean electrical power from the kinetic energy of flowing water. Design insipration from the Club Med Finolhu Villas in the Maldives (3) is sought for its solar panel shade structure. The villa’s solar panels generate around 1 MW of energy per day. Excess energy is stored for rainy or cloudy weather.
Based on the current site conditions, the design concept is to Energize, Entertain, and Engage the site and its surroundings. The design seeks to transform the site into a space that could strengthen the community’s relationship with the Willamette River. It seeks to reactivate the water’s edge into a place for contemplation, learning, and exercise.

52
Program Typologies A variety of typologies were explored to reach the goals of the site. To Energize the site, smart turbines would be equipped in the river along with a solar panel shade structure. For entertainment, a canoe launch, tide pool, and various viewing platforms were explored to activate the site and provide cultural and learning opportunities. As engagement tools, the rip rap is designed for seating and extends onto the sand to provide more seating. An outdoor classroom is also explored as a tool to educate the community and its leaders on clean energy practices. In case of emergency, the viewing platform is further explored to serve as a helicopter pad.
Perspective The activated water’s edge allows the community and its leaders to explore the Willamette River and learn of emerging clean energy resources. By slowly integrating clean energy into our dense urban cities, community members and leaders could understand its integral role in our fight against climate change. It allows for a spatial understanding of the technology’s relationship with its consumers and the grid.

Goal The creation of multi-functional, self-sufficient renewable energy infrastructures within the western waterfront in Portland can provide citizens a place for gathering, relaxing, and socializing. The entanglement of social and energy systems creates not only a hyperfunctional landscape, but an aesthetically interesting vista towards the water’s edge.
Site Analysis It is the Portland saturday market square, however there is no sitting area, gathering space, and do not have any nighttime activities. At the daytime, there is just a normal square without fuctions. People like to walk on the water front, however, it is simple and lack of landscape.
Precedent Light Up Light up proposes to generate lighting for over 900 homes, Luna Park, the Palais Theatre, the Esplanade, and the St Kilda Foreshore. The scheme integrates solar, wind, plant fuelcell energy harvesting and battery storage seamlessly within the landscape of St Kilda. A Lightweight tensile structure made from flexible ultra high efficiency solar photovoltaic modules generates 1552 MWh annually. The modules create a light filtered surface over Jacka Boulevard providing 8,600 solar components. It provides improved sun protection on Jacka Boulevard and makes use of the street area as an energy harvesting opportunity. 70% of the energy is generated by solar photovoltaic cells.
References: Adding solar panel on top of Saturday market which will still allowed wind and light come through and create shade space for people at day time. At night, the solar panels are soft lightings which can provide a nighttime activities space. The continuous of the solar panel will extend to W Burnside St to create an educational landmark. Separating Saturday market and gathering and social space which will suit after COVID-19 era. Having bigger gathering space and green landscape combine which will give more comfort and safety area for daily use and Saturday market. 54

Site Analysis
Opportunities
This site is just one block of a twenty-one block linear park along Portland’s waterfront. The park is relatively constant in program throughout its length, so I have delineated 5 types of space in the graphic below: The Busy Street, the occasional Street Pull-Out, the Open Park Space, the Promenade, and the Willamette River. Various opportunities and challenges are called out by letters and numbers.
- Alison Grover
Individual goal Small-scale energy generation and sustainable, alternative transportation both enable and catalyze independence.

Movement corridors in blue and yellow are supplemented by recharge hubs in pink. Providing space to rest, charge devices, and capture solar energy, the hubs promote exercise, active transportation, and smaller gatherings in a postCOVID era. Electric vehicle charge ports allow the remaining cars on Naito Parkway to access clean power. Sporadic existing trees play an important role in this design proposal as they help to shade the area from Oregon’s incessant summer sun, cooling park visitors and increasing efficiency of solar panels.

Commercial Suburban Renewable Energy Landscapes - Sam Alig, Lexi Smaldone, Sophia Lui
Study area Gresham, OR
Introduction We are looking at how to retrofit existing commercial space within the suburb of Gresham, OR and wanted to find a site that is central to the suburb of Portland. We were interested in locating a site that is popular, as we want our design to be visible and integrate well within the site and surrounding area. With a quick search on google maps, we found the Gresham Station, an open air mall in a central location. The site rests between two main thoroughfares, Division street and Burnside with the MAX rail system bisecting though the site. Our site sees a lot of traffic that includes visitors of the mall, people passing by on the two main thoroughfares and the MAX line. The site includes large parking lots, as well as ample roof space that we intend to retrofit with solar and wind energy generation technology. Gresham Station is nestled in the middle of extensive residential neighborhoods and is close to Gresham High School, the Gresham Police Department, Gresham City Hall and two MAX stations.

Walmart is one of the few big box stores actively installing renewable energy. They are striving to be supplied by 100% renewable energy by the end of 2020. Walmart prides itself on its “everyday low prices” and strives to make solar energy more accepted, used, and cost effective. They have three core objectives: developing and installing new renewable energy projects at scale, driving down the cost of renewable energy, and securing cost-effecting and stable renewable energy pricing that is cheaper than utility power. Renewable energy can thrive where natural resources, providers, and financial lenders are available, where there are government incentives, knowledge of electricity costs, a framework for regulations, access to the grid, rooftop rights, and permits.

Goal Transforming parking lots of department/big-box stores into spaces for solar renewable energy production; multi-functionality.
Background research and precedent
https://www.blueoakenergy.com/solar-portfolio/google-solar
Google Headquarters Google Headquarters incorporate solar arrays into rooftops and carports; altogether it is able to provide around 2MWp. The goal of this project was to install as much selfgenerated electricity infrastructure as possible. Solar arrays were also used at the Google Atheletic and Recreation field (GARfield). Solar array modules are located at the bocce ball courts and soccer field.
Design Proposal https://www.blueoakenergy.com/solar-portfolio/abbot-labs-solar-campus
Abbot Labs Solar Campus Abbot Labs Solar Campus is located in Alameda, California and incorporates a solar carport system in the parking lot to power part of the Abbot Labs campus. The solar carport structures are able to provide around 877 GWh a year. They also provide shade for cars, and improves lighting during the nighttime. The project is expected to be able to provide solar energy for the next 25 years (with a five-year operations and maintenance plan). Blue Oak Energy (manufacturer of the solar carports) are able to receive incentives from the utility company, which increases the financial return of the project.
64
This parking lot transformation proposes for the parking spots in front of the mixed-use/residential buildings (previously department stores) to be converted into a community green space, connected with solar canopies and walkways. This space can help power the energy needs of the buildings, as well as serve as a unifying outdoor space for the community.
Programs: 1. Seating and Gathering Solar panel canopies provide shade for seating and gathering spaces as families watch their children play in the playground.
2. Agrivoltaics An agrivoltaics program allows for the community to plant and harvest food, similar to a community garden. This space blends into the Renewable Energy Art Installation Garden.

Residential Suburban Renewable Energy Landscapes - Taylor Bowden, Jiawei Luo, Yeongseo Yu
Study Area Gresham, OR
Introduction Gresham the fourth largest city in Oregon with a population of 105,594 in 2010. It sits northeast of Portland within Multnomah County and covers a mostly flat area of 23 square miles. The town began as small farming settlements but grew rapidly after the 1960s and is now considered a suburb within the Portland Metro area. Gresham, compared to the greater metro area, makes about 30% less median household income, has 1.5 times the rate of poverty, and is home to a significant portion of minorities (largely Hispanic). Our demonstration site is centered around the North Gresham Elementary School (Between SE Stark St. and NW Burnside St; and between SE 212th Ave. and SE 223rd Ave.). The site was chosen for the diversity of housing densities in the area, mostly consisting of single-family homes, some medium-density apartments, and one highdensity assisted living center. There are a few small lots of commercial and open spaces, but the site is primarily residential surrounding the public elementary school. Suburban sprawl is responsible for a lot of environmental impacts, but we can begin to mitigate them with renewable energy. Our group is looking at how residential land in the suburbs can support and be supported by renewable energy to form more resilient and equitable settlements.

Retrofitting Transit
Site Analysis
- Taylor Bowden
There are a few small lots of commercial and open spaces, but the site is primarily residential surrounding the public elementary school. Roads within residential areas often do not connect and end in culdesacs. Wider main roads have up to 5 lanes, as pictured below on 223rd Ave.

Design Proposal Depaving for the Future Looking forward, autonomous vehicles and remote work will likely change our current transit models and the needs of the community. The demand for paved roads will decrease as autonomous vehicles become more accessible and offer more public transit opportunities. Remote work will also become more commonplace, resulting in less commuters on the street. As cities close to urban centers like Portland grow, housing will become more dense, requiring more open space to meet community needs.
Retrofitting Main Streets If we expect there to be less traffic on roadways, we can begin to envision new ways to utilize streets that can encorporate solar energy, manage stormwater, and beautify our communities. Making renewable energy common practice in these public roadways is an important step in making communities like Gresham more resilient in the face of disaster, injustic, and climate change.
Reducing Culdesacs Culdesacs are an unfortunate waste of space in a future with less cars. Culdesacs are characterized by how they dead-end, making them already low-traffic. If people have less of a need for cars, areas like culdesacs could be redesigned into tiny parks for neighbors to encourge human connection. Where housing density increases, community spaces like this can help fill demand for open space and result in more equitable neighborhoods.

Tree shades VS PV panels - Yeongseo Yu
Goal This research investigates the conflict between tree shades and PV panels on the roof. and the specific goal here is to find proper certain distances between a house and a tree to avoid shade conflict that might occur on the roof.
Analysis - 3D simulation for tree shade 1,3
The research question was how far should houses and trees apart from each other. In order to figure it out, I simulated it by using SketchUp. Firstly, there were so many variables relating to this conflict so I had to scope more narrow down to derive a clear conclusion. So I made two types of houses, one story, and two-story house, and then consider three solar azimuths like south, south-east, and southwest, and then, I experiment what distances between house and trees can avoid the shade conflicts in different months. In a year, I considered the following three types of the period because I wanted to consider the number of sunny days. so, type [A] is months which have lots of sunny days like summer season. Type [b] is slightly more than the summer season, and type [C] is the period slightly including winter season with the summer. Two story house
One story house
South West
Background and site
The research site is Gresham, Oregon, which is located northeast part of Portland. A hundred thousand people live there. Gresham is a mostly flat area, and It was a farming settlement in the past, but now it is a suburban of Portland. The notable fact is that Gresham tend to make 30% less household income than Portland, and it has 1.5 times the poverty rate than Portland. We specifically chose a low-density residential area as a research site.
Analysis - solar radiation
South South East Basic info of Gresham

In order to check the feasibility of solar energy technologies, we conducted a brief solar radiation analysis by GIS, as a result, we found that the most Gresham areas have overall good solar radiation condition for energy generation. In the case of the middle analysis, solar radiation for building, is not accurate analysis due to the lack of securing DSM data, so we just tried to refer this analysis to check a brief tendency for solar radiation on buildings. Also, we tried to convert the solar radiation range to five relative scales in order to compare the brief tendency of solar radiation. • •

Result
This table shows my simulation result. firstly, trees should apart from the house far more in the case of two-story house than one story. Considering the day times in each month in Gresham, I concluded that the Type [b] period would likely be the most efficient for solar energy production. So, the trees should be planted at least far from as much as those distances at different azimuths. Simulation results

Suggestion #1: Planting strategies
1,2,3,4
I suggest tree planting strategies not only to promote the energysaving effects but also to minimize the shade conflicts. In the west and east side medium to large size trees should be planted not only to secure privacy for the outside but also to block direct sunlight when either sunrise and sunset. And at the same time, the aesthetic planting should be considered near the entrance, and in the northern part, evergreen trees should be planted to block winter wind. Finally, in the Southern aspect, the deciduous trees should be planted to cool by providing shades in summer and to heat by getting more sunlight in winter. The trees on the southern aspect should be apart from the house as much as the distance as mentioned in the table.
References
Suggestion #2: Agrovoltaic 5
This is my second suggestion, agrovoltiac, If we make agrovoltaic in the garden or unused land, it would bring us more energy production opportunity during the summer, and it also can give us opportunities to grow some crops. Therefore, it will be helpful in getting some organic vegetables and to save energy. For the planting strategy, I think low height screen planting such as shrubs should be planted between agrovoltaic and houses to block the low-quality view seeing from the inside of the house. Except for the northern part of agrovotliac, trees should be planted apart from the agrovoltaic to avoid tree shades. Plant species could be lettuce, tomatoes, eggplants and etc. and finally the photovoltaic panels should be elevated at least 7’’ over the ground to allow people to cultivate crops easily.

Renewable Energy Optimal Locations
Site Analysis: Within our chosen site, creating a sun radiation plan would help me to estimate the sun radiation levels. In this Sun radiation plan, the solar radiation is much stronger on the bottom right corner and slowly reduces towards the upper left corner.
- Jiawei Luo
Goal Define the proper location for different kinds of renewable energy installation for maximum benefit within residential sites.
Background Research & Precedents There are many renewable energy could be use in residential areas. However, in order to maximize the efficiency of renewable energy, there are five renewable energy are the best for this task among other renewable energy which are: Rooftop solar panels, solar water heater, tubular skylight, wind turbines and tesla powerwall.
-One of the most popular and effective ways to produce renewable energy is with photovoltaic (PV) panels.
-Solar-powered water heaters are similar to PV solar panels, except that instead of producing electricity, they heat water.
-Tubular skylights donâ&#x20AC;&#x2122;t actually create electricity, they do produce free natural light for your home, which can slash your electric-light bill. -A tubular skylight, which is often called a Sun Tunnel, consists of a clear roof-mounted dome, round metal tube, and ceiling diffuser. The metal tube runs between the dome on the roof and the diffuser mounted to the ceiling.
-Technically, the Tesla Powerwall (and other similar large rechargeable battery) isnâ&#x20AC;&#x2122;t exactly renewable energy, but it does work well with any home renewable generator and can even save you money without any other renewable systems
72
-Wind turbines are most commonly found on large tracts of open land, called wind farms, or floating offshore. But, if you have enough real estate you can install a small wind turbine on your property to power your home.
-The inside surface of the tube has a highly reflective, mirror-like coating that reflects over 90% of sunlight and delivers it through the diffuser, which produces a soft, radiant glow of natural light.
In general, placing rooftop solar panels and the solar water heaters on the high level of sun radiation areas would the priority; then placing the wind turbines in a large, open and broad area to capture more wind; tubular skylights could place in low to medium sun radiation area would be fine as long as no tree blocking the sunlight; lastly, the tesla powerwall could support housing with low sun radiation or sunlight block by large tree canopy.
Design Proposal: Identify optimal locations for solar panels in residential areas
Residential-Wind Turbines
Residential-Rooftop Solar Panels
Residential-Solar Water Heater
Residential-Turbular Skylights
Multifunctional/Apt Housing-Solar Panels
Strategies: • Solar panels should be installed at medium to high sun radiation area; No trees blocking sunlight • Wind turbines should install at broad open space; no trees blocking wind • The water heater should be installed at medium to high sun radiation areas • The tubular skylight should be installed at medium sun radiation area • Tesla powerwall should be installed at bad position housing units

Study area Regional Inventory According to the NW Power & Conservation Councilâ&#x20AC;&#x2122;s map of power generation in the northwest, the NE Oregon region has : 26 wind energy sites totaling an output of 2,263 MW of power and 6 solar energy sites totaling an output of 27 MW of power.

Rural Agriculture: Co-location with livestock - Liz Koonce Co-location of energy landscapes with grazing livestock provides twice the utility on the same amount of land while also preserving of agricultural land while still increasing renewable energy landscapes. This approach offers direct benefits to small and largescale sheep and cattle farmers, and is a profitable, herbicide-free, and climate-resilient agrivoltaic strategy.
Site Analysis The best of both worlds According to information provided by the National Renewable Energy Laboratory (NREL), rural north-eastern Oregon has enormous potential for large-scale wind resource collection at 140-meter hub height, and higher-than-average potential for solar resource collection. I chose a mostly unforested site on a butte, with high exposure to wind and sunlight, as well as a diverse terrain that will accomodate the varying landscape requirements of both cattle and sheep.
Precedent Study Sheep & Solar 2018 case study focused on large-scale solar using grazing sheep to maintain multi-acre sites of ground-mounted solar panels and found drastic reductions in labor costs.
Design Proposal Site Selection Using the BLMâ&#x20AC;&#x2122;s map of grazing alotments in north-eastern Oregon, I selected a 2,000acre parcel which is zoned to be grazed by either sheep or cattle, named Courtney Butte. The sitealso has the benefit of having an access road and flat area with existing outbuildings.
Design concept The implementation of large-scale solar and wind energy sites in rural eastern Oregon without the loss of agricultural lands is possible with a co-location approach benefiting both livestock farmers and solar utility companies. A cohesive design approach that takes into account the interests of farmers and energy companies by making use of public land grazing alotments is the key element of this proposal.

Site Plan
Perspective Photoshop renderings showing the utilization of photovoltaic and wind energy infrastructures on the siteâ&#x20AC;&#x2122;s different landscape typologies, co-located with cattle and sheep.
Program Typologies Cattle need larger ranges than sheep, but are also able utilize steeper and more arid terrain than sheep. Sheep are short enough to graze beneath solar panels, and have been found in case studies to ignore panels without damaging them. It is recommended that sheep be rotated in smaller pastures to avoid overgrazing, as is common in the sheep industry. Due to cattleâ&#x20AC;&#x2122;s size and strength, they cannot graze under or around solar panels safely, and are best suited to grazing near wind turbines, and have even been found to utilize the shade provided by turbines on their range. Therefore this proposal involves two landscape typologies; generally flat land co-located by sheep pastures and solar panels and larger swathes of steeper, more rough terrain co-located by cattle and wind turbines.

Net-Zero Migrant Housing
Site Analysis
- Alissa Brunkhorst
Solar panels located on the roofs of these homes will be the main source of renewable energy available. This requires a Sun Path diagram analysis to accurately place solar panels. The use of solar energy allows the net-zero village to have a more reliable source of energy to save and re-distribute at will. Other forms of more energy democracy would be smaller and more on a beta test platform.
Goal The Individual Goal of this project is to provide an excellent example of energy democracy by creating a net-zero migrant housing project in Milton-Freewater, OR. The vast majority of migrants in Umatilla county are Hispanic and working as either legal or illegal farmworkers. By providing housing to this population, it will provide much needed resources and potentially be used for community support services in times of crisis.

This site was chosen by locating the highest Hispanic population in Umatilla County, as numerous resources site that Hispanic populations are more likely to be exploited by farms and have less access to resources. The Seven Hills Vineyard is nearby, meaning that there will be a source of work / income for these people. The site is located near a bus-stop, allowing people to easily transport to either work or grocery stores. Due to the larger size of this lot in comparison to OVE, I believe that there is potential for more permanent structures and more resources.
Due to the larger size of this site in comparison to OVE, larger and more permanent structures are required. The first design draft includes two mini-villages, separated by a larger plaza area, where the village can host resources and community events. In addition to this the plaza area will be used to test other forms of renewable energy. The plaza area will also promote a community space, allowing residents to mingle and form close bonds with each other. In the corners of the site, there will garden sites where residents can grow food, herbs, or commercial products. However, the main goal of these areas is to provide areas of peace and safety to residents, as studies show that plants help boost mental and physical health.

This plot is 116.91 acres of currently vacant land immediately to the west of the town of Cove (population: 609) in Union Co., Oregon. A gentle north easterly slope and high desert solar exposure are vital for growing food as well as placing solar panels to collect and store clean energy. Dividing the site into 4 even width vertical bands was the first step in calculating acreage, systematically demonstrating the amount of money earned and energy collected per area of site usage. 26.11 AC

Majority of Oregon is comprised of rural agricultural communities. More often than not, these towns are vulnerable to economic hardship due to their size and isolation. Through the utilization of land on the market (such as the demonstration site), or cooperating with current landowners to redevelop their agricultural operations there are many opportunities for solar energy for rural Oregon.

Floatovoltaics in NE Oregon
Site Selection
- David Pauls
Goal Increase energy resilience in the region by providing a diverse array of renewable energy. While Increase community interaction with renewable energy systems, so they better understand their role and implication for the future. By Locating floatovoltaics in the most suitable sites where hyper functionality with a diverse set of programs, low impact, and easy access can all be attained.
References To find a suitable site in the North East region of Oregon multiple criteria were considered to find the most suitable site for floatovoltaic array. The criteria for the sites were to have low biological value and be an artificial lake, have easy access for development, be close to communities, have close proximity to the existing power grid, have some type of recreation on the lake, and have water levels that can be controlled from a dam. This lead to the selection of 8 different sites in the region show in the map in the upper left. Among those 8, Thief Valley Reservoir was deemed the most suitable by conforming to most of the criteria stated above.

Background research and precedent Yamakura Dam FPV project Floatovoltaics offer great opportunities to generate power on water bodies. The systems typically have a 30 year life span. Taking less heavy equipment to install building these arrays is often less environmentally impactful to the sites than traditional solar farms. The added benefit of having solar panels on the water is they can be arrayed in higher densities and the water helps help the panels cooler and thus making them more efficient. The panels also have the added benefit of helping to keep the water cool and support fish habitat in their locations. 10,000 square meters of floatovoltacis have the ability to create one megawatt which is around 2.4 acres. The Yamakura Dam project in Japan is a large floatovoltaic array situated on a reservoir. Covering 180,000 square meters and producing 17,170 megawatts that the helps to power 4970 homes. The system is located next to a hydroelectric dam and easy access to the existing grid. 84

It is located outside Union City and in between Baker city and La Grande, providing easy access to these communities to the lake for water recreation and camping. The lake also site close to a existing Wind turbine field and would provide easy access for the floatovoltacis to hook into.
Design concept By the late 1980s, researchers in landscape architecture discipline too embraced advocacy and participatory research approaches (Deming & Swaffield, 2011; Hester, 2006; Linehan & Gross, 1998). Landscape architecture practice has already extensively applied participatory design.
- The 3.5 acres = 1 megawatt of solar -Each square is equal to one acre -64 acres / 3.5 = 18.2 megawatts -Enough to power around 6,000 homes -Less than 10% of Thief Valley Reservoir Surface
Section The section below and the two zoom ins help to illustrate the design goal in retrofitting the lake to generate more power for the region. The camp ground will be improved to create a better camping experience and hopefully draw more users to the lake, by having more amenities and better lake access. The floatovoltaics array will be developed in the center of the lake where the water level will be impacted less from seasonal changes, The anchoring system for the floatovoltacis will incorporate artificial fish habitat structures to hopefully boost the fish population and fish recreation on the lake. All helping to increase community engagement with the lake and the floatovoltaics array that is helping power their communities. The close proximity to the wind farm will hopefully insure that there is a easy conncetion for the floatovoltaics to join the exisinting power grid. The dam that creates the lake could also hold some potential for generating some hydro electrice power for the area too. Making the lake and the adajcent area around highly productive in producing power for the surround communities. Making them more sustainable and more resilient for our uncertain future with climate change.

The redevelopment of brownfield sites can help relieve the stress on greenfield sites for green energy development. Traditional redevelopment of AML’s may not be suitable due to remote location or environmental conditions.1 There are many proposed projects for this type of development. Recently the Cooley Quarry Solar Farm in Novato, California was installed on 11.5 acres of a privately owned serpentine rock quarry and will supply enough energy to power 500 homes.2 https://www.marinij.com/2017/04/25/novato-solar-farm-nearly-ready-to-power-homes/

Thermal Energy Storage - Amanda Craig
Goal Increase the resilience and diversity of N.E. Oregon’s renewable energy production, decreasing Oregon’s use of hydro-power and dams. While providing sustainable energy storage accessible to rural communities generally, as well as in times of crisis or disaster.

Background research / Precedent Based on the research and analysis the Sustainable Evaluation of Energy Storage Solution Technologies 2017, from the Institute for Sustainable Futures, Thermal Energy Storage is the form of energy storage that meets the majority of the individual goals. One remaining concern is the use of water in the storage and conversion process, which in rural N.E. Oregon is potentially problematic, due to seasonal fluctuations, drought and climate change.
TES in Hamburg, Germany
Commissioned in 2019, Hamburgs 24-hour thermal energy storage facility uses over 1,000 tons of metamorphic rock which provides a thermal storage capacity of 130 MWg of electricity energy at charging temperatures of 750 degrees celcius. The rocks are heated using energy obtained through solar and wind sources and then re-converted into electricity through stream. A generator produces electricity of about 1.5 MW. This Project achieved 95% heat storage efficiency, in a 24 hour period this system provides energy supplies to around 3,00 avg. German households. Excess energy, usually due to seasonal fluctuations in wind and solar radiation rates is feed into the local energy grid.

Site Selection
Site Analysis Environmental Analysis was done in relation to resilience to natural disasters in this area, particularly flooding and earthquakes. The wind farm sites as well as the TES potential site are out of seasonal and 100 year flood plains as well as low exposure to impacts from the future Cascadia Earthquake event. Additionally, there are other environmental concerns that would need to be addressed which include; the sites adjacency to water-bodies; ESA/TSA listed species and habitats, BLM land interests and politics, the financial costs, and the potential need for post industrial site clean up for hazardous waste.
Using the regional analysis by the BLM and DOE, Lime, OR was selected due to its proximity to two privately owned and operated wind farms. The city of Lime is an unincorporated-abandoned community is halfway between Baker City and Ontario on Interstate 84, surrounded by BLM land. The Lime Wind Farms lease BLM land, using re-purposed wind-turbines, the farm delivers electricity into the local grid, transmitted to Idaho Power Company and sold under the guidelines of the Public Utility Regulatory Policy Act (PURPA) for Oregon and provides enough energy to run 800 households. In Lime proper, just off the interstate is the post industrial site that was once Portland Cement Factory, now abandoned, is the sit selected for a potential TES facility. This industrial site would suit the needs of a TES facility due to its; proximity to the existing wind farms as well as its existing infrastructure, including adjacent transmission lines, interstate and railroad. Additionally, the surrounding BLM land has the potential for the expansion of the wind farms as well as additional solar farming.
Section
References
Design Proposal The existing abandoned Portland Cement Factory and property is refurbished, and clean-up, for the installation of a thermal energy storage facility. Like Hamburg, this facility will utilize the adjacent wind farms, and potential expansion, energy production to store energy as heat. This would provide more general energy for adjacent communities, as well as provide energy storage that could be used during times of crisis or disaster. Being a rural communities, they are the last to be served/repaired in energy outages. Additional transmission lines and/or a substation could be added to support a greater TES capacity.

Wallowa Whitman National Forest - Our Carbon Sink - Annie Williams
Individual goal
Site Analysis From Flourishing Forest to Timber Commodity First large scale logging in the Wallowa Whitman area began as a means to support western European colonial settlements, their mining operations, and rail road construction. It soon became targeted by many distant outside entities looking for profit. Since its becoming a National Forest, the The USFS has been frequently portioning off areas for timber sales and cattle grazing to supplement their own budget. Boise Cascade, based in Idaho state, is now the largest extractor of timber from the Wallowa Whitman. Nearly all of the wood products are processed nearby, but shipped and sold outside of the surrounding communities (3).
Outline a plan to support the local community on their transition to net zero carbon emissions and increase the areas resiliency in the face of the global climate crisis through resilient forest management.v
See source (1)
Background research
Map provided by Oregon Wild
Levels of sequestered carbon based on management Several studies have been released showing that the sequestered carbon levels of unmanaged forests are higher than managed forests. This is largely due to the higher levels of under-story and middle story vegetation (1). Many other studies have suggested that natural healthy forest is also more resilient in the case of wildfire, disease, and insect outbreaks which are on the rise due to global climate change (2).
Site Selection The Wallowa Whitman National Forest is a prominant 2.3 million acre area in this north eastern Oregon region. It is composed of various landscape typologies but mostly dominated by conifer forest. It contains one National Scenic Area, ten Wild and Scenic Rivers, and four Wilderness Areas. It is bordered by the Umatilla and Malheur National Forests. The area was originally home to the Nez Perce Indigenous People (5). GIS data provided by Oregon Spacial Data Library
90
Design concept The purpose of this project is to explore this forestâ&#x20AC;&#x2122;s greatest potential as a regional carbon sink, to eventually phase out all logging for this purpose, and to give the area the same protections as a wilderness area. It is not focused on economic incentive. Logged areas will be restored, areas under transmission lines will be managed for native meadow, and perscribed burning will replace selective logging as the chosen wildfire management practice. In this state, it will not only offer valuable carbon sequestration abilities but also prime habitat and a rare recreational experience. It could be a precedent for a new style of forest management across the country.
Site Plan
Program Typologies The diagram to the right represents the varrying abilities of certain forest typologies to sequester carbon. Clear cut areas are only able to hold carbon in their soils which is also reduced because of damage from heavy machinery.
Discussion The Paris Climate Agreement explicitly discusses the need for “negative emissions” to be part of the climate crisis solution. Carbon sequestration by forests falls into this category. By protecting their health, we are also protecting humanity’s. While economic benefits will be reduced with decreased logging, many other benefits will be realized. We must act quickly and strongly if we are to make a big enough difference to save the planet. Protecting this valuable forest resource for clean air, clear water, diverse ecosystems and fire and drought resiliency should not be too radical a proposal.
These areas may also release more carbon from dead root and debrit decomposition. Plantation style plots sequester some carbon but have other disadvantages such has high risk of severe mortality in the case of a disease or insect outbreak. Managed forests are better than plantations, however they also have their nutrient cycle depleted by selective logging and root damage from heavy machinery. They also require that access roads be built which fragments habitat and disturbs wildlife. Unmanaged forests have been shown to sequester and hold the most carbon, largely due to a higher volume of above ground vegetation. Once mature, they are also the most resilient in the case of wildfire, have the highest water quality, and most robust and healthy ecosystems (1).

Regional Inventory + Analysis
Wave Energy for Warrenton,OR - Carolyn Corl, Caroline Fitzpatrick, Hana Ketterer
Group Goal Our goal is to design community-focused wave energy infrastructure and transmission in the coastal community Warrenton, OR that addresses pre and post disaster resilience strategies towards sea level rise, earthquakes, tsunamis.
Study area
Warrenton Population: 5,6021, Warrenton Population Density: 416 per sq mi. Based on the location of Warrenton’s existing substation, tsunami evactuation routes and coastal access, an off-shore wave energy system should be sited near the drop-off zone with a power generation facility located in an upland location out of the tsunami inundation zone. Interference with ships and boats is also a concern, so siting the wave energy in Camp Rilea’s military “danger zone” is suitable.2 Siting a community center near the town’s evacuation zone in an upland setting where wave energy can be transmitted is another important site requirement. Due to the community’s sparse population density a familiar community center meeting point that can gather people will be important during a distater even.
Rationals + Assumptions By focusing on a small, relatively isolated coastal community like Warrenton, OR, we can create a small-scale model for implementing wave energy in a location that is vulnerable to tsunamis and earthquakes. In the event of a disaster, we can assume that Warrenton’s access to electricity will be cut off from the larger state-wide grid that currently supports it. The Bonneville Power Administration, which powers most of Oregon through hydroelectric dam projects, is resposible for Warrenton’s transmission.1 Based on the isolaed location in a tsunami zone and near the Cascadia fault line, it is to be expected that Warrenton’s grid would be entirely disconnetected from BPA transmission lines that run up the Columbia river. The Oregon Coast has been identified as a suitable location for wave energy genertion by the Northwest National Marine Renewable Energy Center, listing this region as a potential site.1

Wave Energy Buoy Array and Seaweed Farm
Site Selection + Analysis Offshore Buoy Array Siting This site was originally identified by the Northwest National Marine Renewable Energy Center because of the varying depths directly off the coast, the upland military land that could house generation facilities, and the “danger zone” that prohibits seafaring vessels from entering the area outside of the military training area’s beach. It is also located close enough to the existing power substation to transmit generated wave energy along HWY 101 toward the proposed community center.

Design Proposal
Garden Island Microgrid and CETO Wave Energy Technology
This proposal acknowledges the fragile habitat type that exists in the Oregon Coast in this location and chooses the installation of this wave energy buoy system to be offset with a restoration of the seafloor habitat that extends across the benthic zone. Keeping the buoy array close together also minimizes environmental impact of this new offshore wave energy infrastructure.
Carnegie Clean Energies has tested and used their CETO wave energy buoy system to power a military base in Australia called Garden Island. By using the movement of the large metal buoys to pump pressurized water into an onshore turbine facility, 30% of this grid is supported by wave energy.1 https://www. theguardian. com/environment/2019/ jun/11/ingredient-changing-fortunes-alaska-seaweed-kelp

Seaweed Farming
References
Seaweed farms are growing in popularity due to their ability to absorb CO2 from the ocean, provide food for people and livestock, create untapped economic opportunity, and use as a plastic alternative.2 Growth units strung on ropes can easily be attached to the CETO buoys at varying depths.

Site Plan
Site Features Water pumped in buried pipes to onshore power generation facility
In order to support the population of Warrenton in the event of a tsunami, earthquake, or flood, enough energy will need to be generated and stored. Each CETO buoy in its latest testing phase can conduct a maximum of 1.5 MW1 at its capacity. Based on average houshold energy consumption, this means that each buoy could theoretically produce enough energy to support 1204 people. To support the entire population and have some extra left over, five CETO buoys will be installed off of the coast. As these buoys move with the ocean to produce energy, seaweed farms will produce food and economic opportunity while absorbing some of the ocean’s carbon.

Program Typologies
Seaweed farm
This subsurface design aims to minimize disturbance to the existing ecosystem, both onshore and offshore. The CETO buoy does not allow for entanglement of sea life like other turbine-based tidal energy does. Seabirds also remain unimpacted by this design as it is fully submerged out of site. Another goal for this project is to postively impact disturbed seafloor habitat with a complete benthic zone restoration done in phases. Seaweed farms also provide a noninvasive habitat structure in the water column. These three typologies show the benefits of colocating function with wave energy.

This image shows what the system may look like within a few years of installation. With the benthic zone of the seafloor restored to its previous state, organisms like Dungeness crabs, Pacific Sanddab, English sole and Showy Snailfish2 will be able to thrive there, also supporting local fisheries in the area.
Seaweed farming
7.5 MW capacity buoy array captures ocean’s energy
Restoration of seafloor habitat
The buoys will need to be attached at a depth from 60 to 70 feet deep to be submerged but also be moved by the ocean’s current. Seaweed farm depths will need to be experimented with to figure out at what depth the seaweed can still successfully photosynthesize in relation to its buoy attachments. With smaller floating buoys supporting the seaweed, the depth of the seaweed farm is easily adjusted below the sea surface.

Community Hub
Site Analysis and Selection
- Hana Ketterer
The first priority for selecting a site for the community hub was making sure it is outside any hazard area or evactuation zone. The second priority is that the site still be within the city limits of Warrenton and easily accesbile for daily use so it will be familiar to the community and easy to get to in the event of a natural disaster. As seen in the image below, the selected site (in orange square) is outsite the distant tsunami evacuation zone as well as the local Cascadia earthquake and tsunami evacution zone and just a 5 min drive from downtown.
Outside Evacuation Zone
Goal My goal is to provide a community hub for Warrenton, OR that supports community development and self-sufficiency on a daily basis and also serves as a post-disaster relief center

Design Proposal Design concept In relation to the wave energy buoy array, the community center is located Northeast of the offshore energy generation site and accessed not only by car but also through recreational trails along transmission lines, as seen in the previous two pages. The concept for the community hub is to be a multifunctional space that provides daily community building opportunities that contribute to community resilience for post-disaster relief.

Site Plan
Program Typologies The programming has two main drivers, day-to-day function and post-disaster relief. Daily, the Community Hub holds a community garden, outreach programs hosted at the Community Center building centered around sustainability and renewable energy, a farmers market for the garden and other local vendors, and the building is off-the-grid and powered from the wave energy generation. In the event of a natural disaster, the site can host rapidly deployable shelters, continue growth at the community garden and have power, and act as a drop spot for supplies to be distributed to community members.
The site plan above shows the site and surrounding context. The Community Center Building is located right off of SE Ensign Ln with the community garden and farmers market surrounding the building. The site is large enough to host recreational trails and a large number of deployable tents post disaster. The images below show the flexible relationship between the building, landscape and programming on a daily basis and how the space responds post disaster as a community support center to hand out supplies and food and host temporary shelters.

Wind
due to several recent economic and technical advancements in floatable wind energy technologies. Astoria, Oregon is a relatively windy place. Being located at the mouth of the Columbia River Valley, wind speeds are typically lower when compared to the upper valley. However, wind speeds are very steady here and typically range from 8 to 18 meters per second (17.8 to 40.2 mph)3. These higher values are right at maximum generation value3.

Aquaculture
Coastal Resilience
Wind has strong potential as a renewable energy source and its capacity is rapidly expanding in the United States1. The state of Oregon has substantial wind power resources, ranking in the top ten states for wind farm installation but this energy source only accounts for 12.1% of annual energy generated and the majority is located onshore1. https://www.theguardian.com/environ-
Project Goals
ment/2017/sep/18/green-finance-taskforce-business-investment-clean-energy-infrastructure
• Coastal Communities This project proposal aims to provide resilience to coastal communities through the planning of sustainable, renewable energy systems. Potential natural disasters and the effects of climate change are considered in the planning, design, and suggested management of the proposed wind energy project.
• Wind Power This sustainable wind farm provides economic support through multi-modal land uses, ecological security, and community-wide resilience to natural disasters. Because the majority of Oregon’s energy is consumed by inhabitants of the Willamette Valley, we seek to reduce transmission distance while also supporting coastal communities selfsufficient.
• Energy System Phases This project proposes the appropriate siting and integration of wind farm technology with aquacultural farming practices off the shores of Astoria, Oregon. The energy system was divided into three stages of focus: generation, transmission, and distribution.
Wind Potential There is much wind potential off the Oregon coast. A recent study by the National Renewable Energy Laboratory (NREL) suggested incorporating floating wind turbines at five sites along the coast of Oregon, Site 1 being adjacent to Astoria3. This study also found a 40% decrease in costs compared to a 2016 analysis2. This means that floating wind energy systems may only cost around $60 MWh compared to $58 MWh for onshore systems by 20302. This is 101
Aquaculture is an established industry in the United States. There are several forms of aquaculture products and Oregon is a known supplier of the national industry, especially for farmed salmon and oysters. Today, there are around 2,839 documented aquacultural farms throughout the country4. In 2018, aquacultural sales accumulated $1.5 billion4. This is important when considering how much we import as a country, with most of our seafood being caught fish versus farmed4. This type of fishing leads to resource depletion and has a larger carbon footprint when compared to farmed seafoods. Astoria has a deeply rooted history in the aquacultural industry and its respective farming practices. Home to several well-known regionally scaled canneries, Astoria’s economic resilience may be attributed to its abundance of local seafood and connection to the Columbia River. Along with fish canneries, Astoria features several oyster farms and seafood companies, like Jolly Roger Oysters & Northwest Wild Products, specializing in mollusk farming that may be interested in working with these wind generation farms to establish offshore long-line practices.
Cascadia Subduction Zone The Cascadia subduction zone is a convergent plate boundary that stretches from northern Vancouver Island in Canada to Northern California in the United States5. The zone varies in width and lies offshore of Oregon. The tectonic processes active in the Cascadia subduction zone are responsible for earthquakes and resulting tsunamis. There have been an estimated 41 earthquakes in the last 10,000 years, ranging from 190 to 1,200 years apart5. The last recorded was in 1700 with a 9.0 magnitude6. With this geological knowledge, scientists predict a future 9.0+ earthquake along the Cascadia subduction zone effecting Oregon west of the I-5 corridor and resulting in a tsunami of up to 100 feet to hit the Oregon coast5.

Climate change is also an active force of change affecting the Oregon coast. Scientists predict an average temperature increase of 0.2-1 degrees Fahrenheit per decade and an average precipitation decrease by 14% by 20806. These changes in temperature and moisture will result in higher intensity storms and the expected human population growth will increase carbon emissions and other pollutants6.

Precedents Speculative Designs for Energy Democracy in Puerto Rico A University of Pennsylvania landscape architecture studio aimed to learn from the failed response after Hurricane Maria in Puerto Rico, envisioning possibilities for improving resilience to future disasters focused not only on recovery but also community autonomy and power7. Students designed a network of public plaza, docks, transportation, shops, services, housing, and community center powered by solar energy for a small coastal town of Húcares7. These developments would serve as “community hubs,” which are locally owned and operated facilities with multifunctional spaces7. Governmental funding and external investment would balance power as tourism and consumers would support facility maintenance7. The multifunctionality of spaces and movement of energy and people towards higher ground is mirrored in the proposed project design.
This feasibility study aimed to ascertain the economic feasibility of an offshore marine aquaculture structure for breeding of marine organisms (bivalves) in tandem with renewable energy systems8. The Nordergründe wind farm is located approximately 17km north of Bremerhaven, Germany in the North Sea8. This wind farm, although considered small, is made up of 18 wind turbines and encompasses an area of about 80 square kilometers or 19,800 acres8. The conditions of this sea are somewhat similar in temperature and wind/wave activity to Oregon’s offshore conditions though the Nordergründe is in 30-meter-deep water7. Ultimately, the wind farm produces 111 megawatts per year, which powers about 100,00 homes in Germany8. The offshore aquaculture plot is about 120 acres and produces an economically viable yield8. These farming systems include traditional long-line farming, cage farming, and hanging systems, such as oyster lanterns8. Altogether, the designers developed and tested these options through a series of prototypes8. This system would substantially reduce required resources and subsequent greenhouse gas emissions by harvesting edible seafood species compared to typical intensive harvesting processes8. If Oregon developed an offshore wind farm in the Pacific Ocean, the principles and ideas presented in this study could have a profound impact on the state’s economy and resilience in terms of sustainable food production. Even if wind farms were applied nearshore, within estuaries like the Tillamook, Coos Bay, or Astoria, there is a vast amount of existing aquaculture infrastructure that may be adapted to work with coastal wind farms.

Final Raster Calculation and Potential Sites Multiplication of Values Associated throughout the Suitability Analysis
Youngs River
ArcGIS was used to analyze the existing slope, landslide risk, zoning, conservation zones, habitat types, and navigation channel to determine potential sites for wind turbines near Astoria, Oregon. Wind turbines are best suited to relatively low slopes, with 0% to 5% as ideal and 6% to 7% as possible for development10. Anything greater than a 7% slope is not suitable for wind turbine development10. It is important that wind farm development is protected from landslides, as damages lead to expensive repairs. Through this raster class analysis, we may ensure higher resilience against potential earthquakes and tsunamis by positioning the wind farm in lower-risk areas. The zones most conducive to wind farm development include coastal estuary, industrial, parks and open space, public, and rural industrial10. Areas with slight and no potential for development are zoned as rural, residential, commercial, and forest10. Most of Astoria’s land cover is classified as residential and rural, which reduces opportunity. Due to the 1986 Bill for Coastal Management, estuary development is allowed and suitable for wind farms10. This bill, managed by the Oregon Coastal Management Program, is the state’s method of zoning estuary waterways for development. These management units are based on discrete ecological, geological, and biophysical characteristics of areas within a waterway11. The tidal marsh and intertidal sand bar zones are not ideal conditions for wind turbine development11. These habitat types have been classified for conservation and do not typically support aquacultural habitat types11. Suitable areas, both based on estuary development units and aquaculture needs, include intertidal flats and upland zone11. Finally, our wind farm development will occur outside of the navigation channel to ensure that the turbines will not disrupt ships and boats traveling through the port. The Columbia River channel is a heavily trafficked shipping lane, so ensuring enough space between the channel and the wind farm will be necessary.
Based on the dimensions and placement requirements established by NREL, three wind farms are proposed to provide renewable wind energy to the local community and beyond. With 4 turbines in Youngs Bay, 35 turbines north of the Columbia River Channel, and 19 turbines in the Columbia River near Mott and Lois Islands, this proposed project could generate 1,972,000 MWh per year, enough energy for Clatsop County residences and much more12. The visibility of turbines from the three main bridges provides public exposure to this renewable energy source and system. The energy generated would follow seacables along the seafloor, through a series of substations and transformers, along a transmission line, and stored at higher ground, outside of the tsunami inundation zone. The transmission line would double as a tsunami evacuation route, leading the community to a safe, open space uphill. At this site, there will be a community center and energy storage facility. In the event of an emergency, evacuees may congregate in this open public space and receive relief services. There would also be space for post-disaster tents and housing units as well as an ample power source.

The proposed coastal wind project site is Astoria, Oregon located in Clatsop County. This city is at the very northwest tip of the state and is one of the largest coastal communities in Oregon with a population of about 10,000 people9. Astoria is where the Columbia River meets the Pacific Ocean and is the oldest city in Oregon. The Port of Astoria is a major port both historically and currently, as the channel is mainly used by the Coast Guard, cruise ships, and industrial and commercial shipments. With the goal of offshore and nearshore wind energy generation for coastal communities, Astoria may be considered a potential hub for the coast region, Portland, and rest of Willamette Valley.

clean, renewable energy for local and regional rapid return on investment $ 7.4 month energy payback1 occupy sandbars that are ! dangerous to boat traffic
CHALLENGES
Coastal wind energy provides a variety of benefits and challenges to consider. Coastal wind farms provide clean, renewable energy for local and regional communities. There is a rapid return on investment as a Siemens Gamesa wind farm has a 7.4-month energy payback period12. In this proposed wind farm project, most of the turbines were placed on sandbars within the Columbia River channel, which are hazardous to boat travel, thus not impeding water traffic. On the other hand, this project would be at risk during the impending earthquake and resulting tsunami, though technology and siting methods are being developed to best withstand a natural disaster. Wind energy has a negative effect on marine animals and birds, though more research is being done to better understand this relationship. As for humans, some are bothered by the noise pollution and sight of wind farms, affecting tourism and property values. Construction and maintenance of wind farms is expensive and complex. Ultimately, wind speeds are faster and steadier offshore than on land but can be unreliable.

The programs that are supported in the near-shore and offshore wind typologies include ecological, economic, and cultural benefits for Astoria. Ecologically, the programming will create habitats and biodiversity between the wind turbines for species like kelp, muscles, salmon and bait fish. Economically, Astoria can benefit monetarily from the generation of wind energy, as this renewable energy source is monetarily efficient. The seafood industry will also benefit financially with the opportunity to harvest from the new habitat creation for aquatic species. Culturally, the production of wind energy being located in the public’s eye can encourage education due to the central placement of the wind turbines. The energy produced will also be stored in evacuation hubs to be used in the event of a natural disaster to assist coastal communities.

Typologies The relationship between wind farms and aquaculture can come in the form of three typologies. The deep-water offshore wind farm has the potential to host a variety of kelp species, baitfish, salmon, and mollusk farming13. The nearshore wind farm, which may occur throughout much of the Columbia River channel, includes mussels and oyster species13. The bases of these wind farms may feature artificial reefs to support local ecologies and reduce coastal erosion by acting as wave breaks. The inter-tidal flat wind farm allows for the growth of native clams and oysters and due to its vicinity to

There is a strong need to incorporate renewable energy in the State of Oregon. This proposal would help establish wind energy within Oregon’s largest coastal community while providing infrastructure to establish low-carbon food production. Through this form of resilience and food security, we may utilize energy as an important asset for both pre and post natural disasters. Ideally, this proposal will be educational and will fortify community relations while democratizing energy for what’s considered a vulnerable community. A growing coalition of groups from across the state have been working to develop Oregon’s Green New Deal, with a seven-point proposal calling for14: 1. Phasing out fossil fuel infrastructure 2. Strong regulation for healthy, breathable air 3. 100% community-owned renewable energy 4. Climate-smart, sustainable farms and forests 5. Action to address transportation emissions 6. Protecting communities already experiencing a changing climate 7. Funding for job training, hiring, and infrastructure to support the changes called for in the plan Supporting Oregon’s Green New Deal, this proposed offshore wind farm with integrated aquaculture provides energy, food, and economic resources to Astoria, Oregon with the potential to increase resiliency during a natural disaster.

Conclusion
Intertidal Flats Wind Farm
Astoria Aqua-Wind Farm Typologies These aquacultural wind farm typologies explore different ways we may produce food while simultaneously boosting local aquatic ecologies. Through this form of multi-modal land use, the Astoria 105
Wind farm may provide much more for coastal communites. These typoologies do so by establishing food security while also reducing wave action by forming natural breakwaters through ecologies. This kind of support will be imperative as the Oregon Coast braces for the expected “Big One”, a high magnitude earthquake stimulated by the Cascadia Subduction Zone, followed by a large tidal wave.
