Commissioners

Xio Alvarez
Housing & Neighborhoods Committee

  
Joined Commission: 2023

Xio Alvarez is a resident of White Center/Highland Park (District 1) and a designer at LMN Architects in downtown Seattle, where she works on projects that bridge between planning and architecture. In addition to project work, she co-leads the firm’s resilience research group. She is interested in leveraging quantitative data about climate, geography, and the built environment with qualitative experiences and stories of neighborhoods and places to tell more complicated and nuanced stories about what it means to adapt to change. An innovative and collaborative designer, she is interested in finding resilient and sustainable ways for people to live together. She approaches her projects with an emphasis on engagement and excels at creating accessible spaces for technical and non-technical stakeholders to talk about complex problems. She is particularly passionate about youth involvement in city design processes.

Previously, Xio worked on heat and flood resilience projects with social justice communities in the Boston area, looking at ways that the design process for plans and projects can build coalitions between communities of color, environmental advocates, and government stakeholders. She has a bachelor’s degree in Urban Studies as well as a Master of Architecture and a Master in City Planning. Her joint Masters thesis research studied how people experiencing homelessness adapt the public spaces of the city, and what the design community could learn from these adaptations in designing a more resilient public realm for all residents.

Outside of the office, Xio can be found biking and busing around the city, hanging out along the Duwamish trying to spot new birds, and taking on ambitious cooking projects.

  Joined Commission: 2021

         



A relatively new Seattle resident of about 7 years, Rose is excited to give back to our community and to collaborate on our collective vision for an equitable, inclusive, and eco-conscious Seattle. Rose nurtures a wellspring of passion for doing right by both people and the environment, shaped by their heritage as the mixed Chinese-Caucasian child of an immigrant; lived experience as a "third culture kid" and environmentalist activist blossoming into an equity-focused and intersectional environmentalist; and learned knowledge of Seattle and the contemporary and historical land use issues affecting our Indigenous, Black, and other minority communities. They also bring professional knowledge of land use policy as a biologist at Jacobs Engineering, with 9 years of environmental investigation and permitting experience for projects ranging from small residential improvements to public transit expansions, and most recently, large bridge replacement and fish passage barrier correction projects. Always learning, always growing, and not afraid to admit when they are wrong, Rose's approach is to listen first, digest by contemplating and asking clarifying questions, and then collaborate on solutions.  A personal note: District 5 residents, please do not hesitate to reach out! I will do my best to bring the North Seattle perspective to our reviews and to support inclusive policies for Seattle as a whole.

Joined Commission: 2024

Dylan Stevenson (Prairie Band Potawatomi descent) is an Assistant Professor in the Department of Urban Design and Planning at the University of Washington where his research examines the relationships among Indigenous Planning, Historic Preservation, and Environmental Planning. He’s specifically interested in restoration and how it informs our collective responses to climate change, land ethics, and Indigenous cultural revitalization. As the field of planning continues to develop approaches so that communities can live more ecologically in the face of climate impacts, he believes it needs to centralize Indigenous worldviews to foster better relationships with the land while promoting Tribal sovereignty and self-determination. Some of his previous research has explored how governments (Federal, State, and Tribal) normalize cultural values within their water planning activities and has published work analyzing diversity, equity, and inclusion (DEI) within planning educational programs. His current work focuses on the role of intangible cultural heritage (language, cultural practices, etc.) within environmental and indigenous planning practices.

Before coming to Seattle, Dylan obtained his Ph.D. in City and Regional Planning and has obtained his AICP certification through the American Planning Association. He additionally holds a Masters in Planning from the University of Southern California, a Bachelor of Arts in Linguistics from the University of California, Davis, and an Associate of Arts in Liberal Arts from De Anza College. Dylan has lived in Seattle since 2022 and currently resides in the Belltown neighborhood.
