Green Thumbs are the eyes and ears of our project sites. With over 60 completed projects in the Portland Metro area, there are a lot of greenspaces to keep tabs on. To ensure the ongoing viability of each site and remain connected to the community, we rely on our Green Thumbs to monitor past project sites and support our partners with needed maintenance activities.


Site monitoring involves documenting site conditions to understand changes over time. Using established photo points, Project Stewards prepare photographic and written updates for past project sites. These updates are used by Depave to evaluate project successes and promote our work, examine long-term design performance, and determine maintenance needs at each site.

Project Stewards are required to:
  • Visit assigned properties at least twice per year (sites require twice yearly monitoring in December and May/June; this can be completed by the same person or two different people).
  • Inspect vegetation and facilities.
  • Take representative photographs of all areas of the site.
  • Interview a sample of on-site users.
  • Prepare a short, written narrative about your observations for submittal to Depave staff.

Depave creates living greenspaces that require ongoing maintenance. While we incorporate a native plant palette appropriate for each site, weeds need to be actively removed for the first few years as plants become established. Maintenance activities also apply to facility infrastructure including inlets, outlets, and pipes.

Common maintenance activities include:
  • Pulling invasive or exotic weeds.
  • Trimming or pruning tall vegetation.
  • Planting new plants.
  • Applying mulch.
  • Removing sediment and/or loosening soil to promote infiltration.
  • Clearing vegetation or other debris from clogged inlets or outlets.
  • Removing and properly disposing trash.

Site maintenance may be accomplished in tandem with site representatives and other volunteer groups.

Project Stewards may work alone or with a group.

Volunteer requirements:
  • Comfortable working independently
  • Comfortable communicating with property owners or site representatives
  • Can distinguish between healthy, native plants and distressed or nonnative species (you don’t need to be an expert)
  • Digital camera or other device to take photographs
  • Excellent written communication skills
  • Access to reliable transportation
  • Committed to Depave’s mission and volunteerism
