The bill aims to enhance environmentally sustainable urban design in Washington state by establishing a center dedicated to promoting health and sustainability in urban environments. It recognizes the significant environmental health disparities in urban areas and the negative impacts of the built environment, such as various forms of pollution. The legislation outlines the center's responsibilities, which include advocating for sustainable design, coordinating with local leaders and the private sector, encouraging workforce development, identifying priority projects, and organizing a biennial design competition. The center will also provide grants for projects that implement environmentally sustainable urban design.

Additionally, the bill creates an advisory council to support the center's mission, ensuring a balanced representation of interests and expertise in urban planning and sustainable architecture. The council will review grant applicants and provide guidance on the center's annual work plan. Furthermore, the bill establishes the environmentally sustainable urban design account in the state treasury, which will fund competitions and grants related to the center's initiatives. The account will receive federal funds, gifts, and grants, with expenditures strictly allocated for the purposes outlined in the legislation.
