Stormwater Utility Services

The Port of Seattle and the Northwest Seaport Alliance require comprehensive stormwater utility services to support their infrastructure and regulatory compliance programs in Seattle, Washington. The issuing agency is seeking assistance with asset evaluation, repair, and rehabilitation, as well as research into regulatory, resilience, and stormwater treatment trends. The selected partner will support the Infrastructure Repair and Upgrade Program by identifying and prioritizing stormwater infrastructure projects and refining existing screening tools. The scope of work covers maintaining accurate stormwater GIS mapping and providing support for tenant and Northwest Seaport Alliance mapping and infrastructure requests. The agency also requires assistance with education and public involvement, specifically with websites and public-facing materials to support elements of the Municipal Separate Storm Sewer System program. Additionally, the service provider must assist with reviewing and training for the construction stormwater control program, researching and developing concept plans for structural controls, and monitoring innovative stormwater treatments to address emerging contaminants, industrial properties, and marine environments. Eligibility is restricted to onshore organizations based in the United States. The agency is looking for proposals to establish the budget for these services, and bidders may submit their responses digitally via email or online. The agency has scheduled a pre-bid meeting for June 23, 2026, and requires all questions regarding this opportunity to be submitted no later than June 25, 2026.
