Park history

Dr. DeNorval Unthank (1899-1977) was born in Pennsylvania, raised in Kansas City, and received his medical degree from Howard University in Washington, DC. He moved to Portland in 1929 to start his own practice. He was on the staff of Good Samaritan, Providence, St. Vincent, and Emanuel Hospitals. After retiring in 1970, he served as a medical consultant for the state workmen’s compensation board until 1976.

He won several awards for his work against racial discrimination as well as for his public service work. In 1958, the Oregon Medical Society named him Doctor of the Year. For his role in bringing down racial barriers, the city of Portland named this park in his honor in 1969. Unthank was the recipient of the distinguished citizenship award from the University of Oregon in 1971 and the citizenship award from Concordia College in 1975. Unthank was the first African American member of the Portland City Club. He was president of the local chapter of the National Association for the Advancement of Colored People (NAACP) and cofounder of the Portland Urban League. Unthank sat on Oregon’s Committee for Equal Rights and the Council of Social Agencies. An important figure in the early civil rights movement in Portland, Unthank opened many doors and opportunities for other minorities.

Potential additions to investigate

Passing the initial size-and-type screen is not a feasibility finding. Usable space, existing uses, habitat, public access, utilities, permission, construction costs, and ongoing maintenance funding require site-specific review. Missing acreage or uncertain classification remains unassessed.

Enabling assets recorded

Evening use — Programming after dusk — leagues, classes, walks.
League play — Organized sport seasons.
Youth drop-in — Free unstructured play with somewhere for adults to sit.
Nature education — Environmental programs and guided walks.
All-weather indoor — Programming that survives a Portland winter.
Markets & festivals — Vendor events and neighborhood festivals.

One addition to investigate

Gatherings & events — needs stage or amphitheater or plaza or terrace
Summer water play — needs splash pad or wading pool or all swimming pools or interactive fountain

Inventory-based screening only. Recorded assets do not establish opening hours, program staffing, permission, or operating funding. Potential additions require review of usable space, habitat, utilities, access, and ongoing maintenance. Unverified properties remain unassessed.

Our reading of the calendar

Which facilities count as in season is our model of Portland's year (splash pads and wading pools in summer; fields, gardens and interactive fountains spring through fall; everything else year-round) — not the City's schedule. Check posted hours for pools, splash pads, and restrooms. From 16 weekly catalog snapshots (2026-06-11 to 2026-10-12). "Programs" are distinct titles; "sections" are the catalog's individual records — a swim level at one time slot for one week is one section. Complete through 2026-10; later months fill in as registration opens. Winter counts fill in when winter registration opens.

Condition across all assets

Citywide condition atlas

Across 53 assessed assets at this park, 23% are in poor or very-bad condition (rated 4–5). Pooled from the City's public assessment layers — buildings, bridges, playgrounds, courts, fields, fences, paths and amenities.

This count comes from the City's rated asset layers; the “Public assets” list below is a separate furnishings inventory, so its items and scores are counted separately and the two totals need not match.

Condition is rated 1 (good) to 5 (very bad); no score means not yet assessed and is excluded. Park trees are inventoried separately and not counted here. These assessment records do not contain repair costs. Historical project estimates are shown separately.

Repair ledger

Each row is one record from PP&R's public asset layer. No itemized repair cost is published for these records, so none is shown. Dates are the source's last published assessment; treat older ones as unverified.
