About this project
As the Angle Lake light rail station's parking garage and plaza are complete, Sound Transit no longer needs an adjacent property. The 33,500-square-foot property was once for construction staging. This land can transition into a transit-oriented development and add 130 affordable homes.
In February 2022, the Sound Transit Board of Directors approved the key business terms with Mercy Housing NW for their Connection Angle Lake project. Connection Angle Lake’s 130 units will bring 508 bedrooms across studio, one-, two-, and three-bedroom homes. These units will serve households earning under 50% and 60% area medium income. The property will dedicate 26 apartments for people with intellectual and developmental disabilities. Eight households will meet the requirements of the project-based voucher program of the King County Housing Authority. The Arc of King County will use the ground floor commercial space as their county headquarters, providing critical services to those with intellectual and developmental disabilities and their families.
Sound Transit discounted the property value to support the project’s affordable housing outcomes. Mercy secured financing for the project from multiple public and private sources, including the Washington State Housing Finance Commission, King County, and the Amazon Housing Equity Fund.
Construction on Mercy Housing NW’s Connection Angle Lake project is ongoing, with targeted completion in mid-2025.
