Seattle Public Utilities: Seward Park CSO Reduction

Seattle, Washington

Construction of the Seward Park portion of the North Henderson Combined Sewer Overflow Reduction project will provide a new underground, 2.65 million gallon, storage tank, plus vaults to house odor control, mechanical and electrical equipment to meet EPA reduction requirements. Integrating shoreline restoration and landscape improvements HBB provided direct collaboration with Seattle Department of Parks and Recreation, which owns and manages Seward Park. HBB presented the design at the stakeholder meetings, including the Friends of Seward Park and the Friends of Seattle Olmsted Park. Our design promotes the aquatic shoreline habitat, to comply with city and federal historic preservation standards, and to preserve the Olmsted character of the park.
