The bill aims to enhance urban forest management in Washington by establishing a framework for local governments to regulate and protect tree canopies while accommodating housing development needs. It emphasizes the importance of tree canopy and green spaces for public health and environmental benefits, such as mitigating urban heat and improving air quality. The Department of Commerce is tasked with creating a model urban forestry ordinance that local governments can adopt voluntarily. This ordinance will prioritize avoiding tree removal, minimizing impacts, and providing mitigation options for any tree removal that occurs during development.

Additionally, the bill amends existing laws to incorporate urban forestry considerations into comprehensive planning and development regulations. It mandates the Department of Commerce to produce guidance on best practices for tree retention, planting, and maintenance, as well as the establishment of tree banks to compensate for tree removal. The model ordinance and guidance must align with municipal stormwater permit requirements and be reviewed periodically to ensure effectiveness. The bill also highlights the need for collaboration with various state agencies and emphasizes the importance of community involvement in the planning process.
