Seattle's $700 million, 2.7-mile subway is designed not for urban transit but for managing wastewater, addressing overflow issues in its combined sewer system during heavy rains. Unfortunately, the architecture only exacerbates the financial burden on residents, with projected utility bill increases of 4-6% annually. Pollution stems largely from stormwater runoff, notably from transport infrastructure, yet the transportation sector contributes nothing toward its mitigation. This disconnect between cause and cost raises equitable concerns in managing urban stormwater.
Seattle's new 2.7 mile subway costs $700 million but only carries wastewater, addressing sewer overflows instead of providing transportation improvements.
The cityâs combined sewer system struggles during heavy rains, leading to pollution issues which disproportionately affect utility bills for residents.
Transportation, responsible for half of the stormwater problem, pays nothing for cleanup costs, while affected residents face rising utility bills.
The current approach to dealing with stormwater is inefficient and inequitable, lacking incentives for reducing private vehicle use.
