Lewis Creek County Park Master Plan

In the winter of 2020 and spring of 2021, Linn County Parks and Recreation conducted the first round of public outreach to gather community perspectives about Lewis Creek Park to help inform the creation of two (2) draft concept plans.  Outreach included conversations with the Sweet Home Chamber of Commerce, Linn County Parks staff, the Linn County Parks and Recreation Commission, Sweet Home Youth Advisory Council, and interviews with members of the Lewis Creek Park community representing the Best in the West Triathlon, Wake the World, Willamette Valley Water-polo, Central Oregon Masters Aquatics, and Camp Attitude.  Linn County Parks and Recreation also conducted an online survey in the winter that received over 500 responses. 


The following summarizes the key points heard across the outreach process that informed the development of the following two concepts:

  • The top priorities for improvements are infrastructure (restrooms, drinking water, power), universal access to water recreation and water safety, and active recreation (open lawn areas, children’s play areas). 
  • Popular potential park features include new restrooms, an improved swimming area, and vehicle parking.  Other high priorities are park amenities (tables, benches, etc.), and walking trails.
