This flood, on Dec. 27, 2022, highlighted how bad things can get in an urban neighborhood on the front lines of climate change. In a city of bluffs and hills, there is perhaps no other place more vulnerable. South Park is low-lying and filled in with homes, businesses and heavy industry. After decades of industrial pollution, discriminatory mortgage-lending practices, known as redlining, and disinvestment, flooding is only the latest injustice Seattle’s largest riverfront community has had to bear.
