Mercy Angle Lake Family Housing (MALFH)

Mission & Concept

At Mercy Angle Lake Family Housing, Mercy seeks to create an inclusive, affordable, and supportive living environment that empowers individuals and families of diverse backgrounds to thrive. We are dedicated to:

  • Promoting Accessibility and Inclusivity: Offering 130 thoughtfully designed units, including 26 specifically tailored for individuals with intellectual and developmental disabilities, to ensure every resident has a comfortable and accommodating home.
  • Enhancing Quality of Life: Providing a variety of unit sizes, from studios to three-bedroom apartments, to meet the diverse needs of our community, fostering a supportive and vibrant neighborhood.
  • Facilitating Connectivity and Convenience: Strategically located adjacent to the Angle Lake Light Rail station, we ensure our residents have easy access to public transportation, connecting them seamlessly to the broader community and essential services.
  • Fostering Community and Support: Collaborating with The Arc of King County to offer on-site services and family support, we are committed to creating a nurturing environment where residents with developmental disabilities receive the care and assistance they need.

Our vision is to build not just homes, but an inclusive community where each individual is valued, supported, and empowered to achieve. Through innovative design, strategic partnerships, and a steadfast commitment to affordability, Mercy Angle Lake Family Housing stands as a beacon of hope and opportunity for all who call it home.

Site Information

This project represents Mercy’s sixth TOD project with Sound Transit. The site was acquired by Mercy from Sound Transit at a substantial discount to its market value. Mercy secured the rights to develop the site through the Sound Transit RFP process.

MALFH will include studios, one-, two-, and three-bedroom units. This wide range of unit sizes ensures that the project will meet the needs of a diverse collection of family structures including individuals, couples, small families and large extended families. Additionally, 26 of these units have been specifically designed to meet the needs of individuals with intellectual and developmental disabilities and their families.

Notable Amenities & Partnerships

  • The Arc of King County will move its headquarters into the 11,000 sf office in development on the ground level of Mercy Angle Lake. The new Arc Legacy Center will provide a platform for The Arc’s expanded service delivery for individuals with IDD and their families living throughout King County and at Mercy Angle Lake.
  • The Arc offers health support, family and life skills training, employment assistance, and community integration programs, while both The Arc and Mercy will work together to foster an inclusive community through educational workshops and advocacy efforts.

Design & Sustainability Features

  • Bike Plaza along S 200th St with secure bike parking and information about nearby transit.
  • Community room that connects to the courtyard for resident outreach and community building, after-school programs, and adult education.
  • Solar panels installed (33 kw PV array).
  • Centralized heat pump hot water system.
  • Additional accessible units beyond code minimum requirements that are designed based on The Arc of King County stakeholder input and lived experience.

Community Engagement

  • The project team collaborated with city staff on a development agreement to reduce the parking requirement from approximately 1.1 stalls per unit to 0.6 stalls per unit, which, along with other land use criteria departures, al-lowed the project to maximize the zoning/building envelope and increase the unit count from 90 units to 130 without any adding parking, while main-taining the goal ratio of 40% family-sized units. The development agreement was unanimously approved by the SeaTac city council, who continue to sup-port the project.
  • The efficient project massing was driven by the triangular site with the long, curved property line on the west side, and 20 feet of grade change from the southwest corner to the north end, which aided in providing 3 levels of park-ing with no internal ramping.
  • The internal courtyard was placed to reduce the sound from the busy adjacent streets as well as the nearby SeaTac airport.

Funding Note

MALFH is supported by the Amazon Housing Equity Fund including a $2 million grant and $15 million in below market rate construction and permanent financing. The Amazon HEF allowed Mercy to expedite the design, permitting and construction of the crucially needed housing, avoiding several additional public funding rounds.
