Along with announcing the upcoming emergency culvert repairs in Fauntleroy, Seattle Public Utilities has announced another project in West Seattle. SPU says work will resume – after almost three years – on a section of its “natural drainage” project near Delridge businesses including The Home Depot and Arco/AM-PM.

Seattle Public Utilities (SPU) is constructing natural drainage systems (NDS) in the Longfellow Creek Basin to address recurring drainage and flooding issues and provide water quality treatment for street runoff that drains to Longfellow Creek. During construction in 2022, crews encountered unexpected underground conditions and the project at this location was postponed. Construction will resume in mid-September 2025.
