Park history

The Foley and Balmer properties were purchased by Metro through the Metro 26-26 bond measure. The Foley property had been used primarily as a stable for over 90 years. Before that it was a rich and lush forest with Tryon Creek running through the heart of it. Today there is an abundance of plant and animal life present. The natural area includes both meadows and forested areas with walking paths and a footbridge crossing Tryon Creek.

Thanks to funding from the voter-approved Parks Replacement Bond, PP&R replaced a bridge in the Foley-Balmer Natural Area and the Owl Creek Bridge in Marshall Park. Both bridges were out of service for several years and the replacements reconnected popular SW trails. The bridge replacements were complete and open for use in October 2019.

Visitor amenities

Published amenities are checked separately from entry conditions. Each links to other documented locations; confirm current hours before visiting.

No visitor activities are verified from the available entry and amenity evidence. Inventory records alone do not establish public use.

What kind of place this is

A natural area: habitat protection and stewardship guide what uses and facilities are appropriate. Classified from official page labels it a natural area; our model.

Through the year

Seasonal facilities and listings captured by the Atlas. These records do not measure attendance, utilization or all activity at the site.

Counts describe captured listings, not attendance or all activity. No listings captured does not mean the site is unused.

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.

How it's holding up

The City's own inventory of what is here and the condition it last recorded for each item. Dates are the source's; old dates mean no newer public assessment, not that nothing has happened since. Historical project estimates appear below; they are separate from these condition records.

Condition across all assets

Citywide condition atlas

Across 1 assessed assets at this park, 0% 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.

Good · 0Above fair · 0Fair · 1Poor · 0Very bad · 0

Pathways & trails

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

Public data does not currently flag repair candidates for this park. Additional PP&R maintenance exports can be added without changing the page structure.
