Seattle Public Utilities will propose two storm-relief options to Madison Valley residents whose homes have been flooded over the last few years. Both options, officials say, should handle the type of rainstorm that occurred last December, when local resident Kate Fleming was drowned in her basement.
The first option, which would cost $16.4 million to $18.8 million, would involve the demolition or moving of 17 homes in the 200 block of 30th Avenue East for a park and part-time pond.
The second option, which would cost $18 million to $28 million, would build a 1.5 million-gallon overflow facility in the Washington Park Arboretum. This plan would include an underground tank or a berm-surrounded area that would take on floodwaters.
Construction on either plan, which would take up to 18 months, wouldn't start until 2009.
The utility will present both options during a public meeting on Thursday, Oct. 4, from 6 to 8 p.m. at the Garfield Community Center, 2323 E. Cherry St.
The city is not pursuing the more expensive option that was preferred by local residents. It involved installing a storm-water pipeline into Lake Washington at a cost of $30 million to $80 million. This option would take up to five years to build.
