The proposed bill aims to enhance environmentally sustainable urban design in Washington state by establishing a center dedicated to promoting health and sustainability in urban environments. The legislation recognizes the significant environmental health disparities in urban areas and the detrimental effects of pollution caused by the built environment, such as noise, light, and water pollution. It emphasizes the importance of innovative architectural and landscape design approaches, including green, biophilic, and regenerative architecture, to improve biodiversity, air quality, and energy efficiency while mitigating negative impacts on ecosystems.

To facilitate these goals, the bill creates a center for environmentally sustainable urban design within the Department of Ecology, which will advocate for sustainable practices, coordinate with local leaders and the private sector, and manage a biennial design competition for priority projects. An advisory council will be established to provide guidance and recommendations for grants and competitions, ensuring a diverse representation of expertise in urban planning and sustainable architecture. Additionally, the bill establishes an account for funding competitions and grants, sourced from federal funds and private donations, to support projects that align with the center's mission.
