Iron Mountain Park is OPEN


Iron Mountain Park is OPEN. Iron Mountain Park is an approximately 51-acre park located in the center of the City of Lake Oswego. Iron Mountain Park is larger than a local neighborhood park and integrates natural and developed features. The Iron Mountain Master Plan, Resolution 17-42 was adopted by the City Council July 18, 2017.  

The Iron Mountain Park Project embodies the goals and vision of Parks Plan 2025 and three years of extensive community-focused outreach from the Iron Mountain Master Plan (2017). Improvements to the site will allow for increased opportunity for nature play, enhanced park access, and preservation of the cultural and ecological history.  Developments will include:

  • Erosion and sediment control, relocation of stream and enhancement of both stream and wetlands;
  • Removal of trees, re-grading on the site and storm water management enhancement;
  • Installation of trees, shrubs, groundcovers, seed mixes, bark mulch, logs, boulders, permanent and temporary irrigation; and
  • Compacted pathways, parking lot, play area, restroom and picnic shelter.

Planning Process Outcomes

The Iron Mountain Park planning process resulted in several deliverables to move forward with developing, restoring and managing the site. Some aspects of the plan and planning process were:

  • Conceptual site design, featuring amenities consistent with Parks Plan 2025 recommendations and design guidelines for Citywide, Integrated Hybrid Character parks (App. K - PP2025).
  • A public engagement program which provided ample opportunities for the community to invest in the future concept of the site. Outreach events were both real time and online.
  • A professional design team translated community input into a high quality professional park design that is uniquely Lake Oswego.

Additionally, the Department worked with highly qualified resource professionals to develop stream and wetland restoration plans. The plans addressed the degraded resources onsite and provided the City with a strategy to restore these resources and their function within our areas watershed. Aspects of this process were:

  • Delineation of resources (Wetlands, Stream Corridors and Tree Groves) according to Department of State Lands and City of Lake Oswego requirements. (COMPLETED)
  • Restoration plan for stream and wetland resources.
