The Arc of King County

What The Arc of King County does

The Arc of King County is a 501(c)(3) nonprofit organization headquartered in SeaTac, Washington, founded in 1936 as the Children's Benevolent League. It serves children and adults with intellectual and developmental disabilities (IDD) and their families across King County throughout the lifespan, from prenatal diagnosis through end-of-life care. The organization is one of 730 chapters of the national Arc network and one of 10 chapters in Washington State, with a staff of 51-100 and an 89-year operating history.

Its service portfolio is delivered directly rather than through a technology platform and includes the Supported Living Program (~45 residents), Information and Family Support (English, Spanish, Korean), Parent to Parent peer mentorship, IEP Parent Partners, Housing Stability case management, Silver Tsunami for aging caregivers, Wings for Autism airport rehearsals at Seattle-Tacoma International Airport, and the Inclusion Academy civic engagement training. The Arc Legacy Center at Connection Angle Lake, developed with Mercy Housing Northwest, adds 26 income-restricted IDD-designated housing units within a 130-unit building. The organization also operates a fee-based professional training catalogue covering DSHS-approved Long-Term Care Worker courses and 20+ Disability Resources and Services Presentations.

Revenue is sourced primarily from Washington State DSHS/DDA contracts for Supported Living, King County Best Starts for Kids and Veterans and Seniors Human Services Levy grants, individual donations and memberships, and modest fee-for-service training revenue (free for King County nonprofits and government entities; $525-$1,500 per session for out-of-county and for-profit customers). Direct services to eligible individuals and families are provided at no charge.
