Portrait of Rose Lew Tsai-Le Whitson  Rose Lew Tsai-Le Whitson 
  Land Use & Transportation Committee Co-Chair

  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. She nurtures a wellspring of passion for doing right by both people and the environment, shaped by her 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. She also brings 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 she's wrong, her 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.
