Project Completed – January 2013
Seattle Public Utilities (SPU) is pleased to announce the completion of the Madison Valley Stormwater Project. Landscaping crews have put the finishing touches on the project area within the southwest corner of Washington Park, and equipment has been demobilized, signifying the end of this important multi-year project.
The Madison Valley Stormwater Project team thanks the community for continued patience and input during this major capital stormwater conveyance and storage project.
Historically, Madison Valley has experienced substantial surface water flooding and sewer backups. After the storm in August 2004, which resulted in significant flooding in Madison Valley, SPU began an in-depth process to develop and evaluate a wide range of options to reduce the potential for stormwater flooding and sewer backups primarily in the vicinity of 30th Avenue East and East John Street. SPU designed and constructed an expansion of the 1 million gallon above-ground stormwater holding area (Phase 1) and also a new stormwater pipeline, storage tank and landscaping (Phase 2). Together, the new infrastructure is capable of containing the amount of stormwater that caused flooding and numerous sewer backups in the two largest storms in 157 years of record – in August 2004 and December 2006. The total cost of both phases of the project and additional drainage improvements is $34.5 million.
