On Monday, Mayor Jenny Durkan announced that Seattle will invest $110 million in affordable housing in 2020. The funds, which come primarily from the sale of the Mercer Megablock and city and state tax revenue, will go toward the construction and redevelopment of 1,944 new units across the city. “We need far more federal resources and… reinvestment if we are going to fully address our housing and homelessness challenges,” said Emily Alvarado, director of the Seattle Office of Housing.
