The legislation updates and clarifies requirements for solid waste storage, staging areas, and access for new residential, commercial, and industrial developments in Seattle. These changes are crucial for efficient solid waste collection services, especially with increased housing density due to the "Middle Housing" law and growth in multifamily housing. The amendments modify Sections 23.49.025, 23.54.040, and 23.84A.036 of the Seattle Municipal Code. Key updates include codifying minimum storage area dimensions, aligning standards with industry safety requirements for collection trucks and dumpsters, and addressing challenges in neighborhoods impacted by increased housing densities. The goal is to ensure appropriate on-site storage and safe, efficient collection, which also contributes to environmental and social justice outcomes.
