Description
The City of Peoria, AZ approached Project Cities and the 2021 MSUS cohort for research on the feasibility, and challenges, of adopting a Community Forestry Program (CFP). The team was asked to evaluate Peoria’s potential for canopy growth and plan adoption by researching forestry or shade programs in cities with similar climates, as well as by conducting citizen outreach to determine the community mandate for a CFP. This process includes identifying the specific barriers and opportunities regarding implementation. Research is being conducted through peer reviewed articles and interviews with shade or forestry program officials; citizen outreach is being conducted through surveys and focus groups. These results will be compiled and presented to the City of Peoria to provide recommendations moving forward. Peoria will likely benefit from a comprehensive CFP, and this program will help reduce inequalities within the city, enhance urban form, promote walkability, and increase biodiversity within the urban area. This will also highlight that Peoria is dedicated to becoming a forerunner in the arena of urban planning, the intersection of social and environmental sustainability, and human health. Through their efforts in this sphere, Peoria can emerge as an example, and provide motivation, for other cities that are interested in pursuing a similar program. If implemented, the CFP will influence the development of Peoria for years to come.

Description
Before the rise in renewable energy, few people considered the consequences of adding large amounts of intermittent power onto the grid. As renewable energy has become more prevalent, utility companies must adapt their business practices to accommodate these unique sources of power. This is leading to challenges on how best to manage a grid with large amounts of renewable power. Arizona Public Service (APS), the largest electricity provider in the state of Arizona, has more than 70,000 distributed solar customers on their grid and the number of solar customers increases every day. With this increase in distributed solar customers comes the solar duck curve—the phenomenon whereby solar produces energy during times of low demand. However, with the use of storage, the duck curve problem may be mitigated. This project examines the sustainability of three storage options: pumped hydro energy storage, compressed air energy storage, and lithium-ion batteries. Using several sustainability indicators, this project makes a policy recommendation to APS on the most sustainable choice for large-scale energy storage. This project found that compressed air energy storage was the most sustainable option for APS. This considered the impacts of compressed air on the environment, communities, and the costs of this storage option. One important aspect to acknowledge regarding this technology is that in its current form, it does emit some carbon emissions. However, the carbon emissions may have less of an impact if this storage facility can allow APS to use its renewable energy assets most efficiently and continue to use energy from Palo Verde, the nuclear facility in Arizona.

Description
This document contains a feasibility study that explores the necessity, collaborations, and
possible methods of installing a 1 megawatt lithium-ion battery storage facility at San Diego Gas
& Electric’s Century Park campus located in the Kearny Mesa neighborhood in central San
Diego, California. The battery will serve purposes of adding renewable energy to the energy mix,
reducing operations costs via peak shaving, an educational component for the region, and
meeting stringent State of California and California Public Utilities Commission mandates for
both renewable energy and battery storage capacity.
