Types of Projects

trail projectThese are examples of some of the types of projects that CWSP grants fund. Many of our projects fit into multiple categories.


Education is a part of every CWSP project. CWSP connects community groups with resources to develop educational events or programs about Portland’s watersheds and natural areas. Innovative workshops, curricula, videos, creative writing, art projects, special events, interpretive signs and data collection for watershed projects are essential to creating a community of watershed stewards.

  • Franklin High School Nature Trail
  • Franciscan Montessori Earth School Window onto Wetlands
  • IRCO Gilbert Park

Pavement Removal and Urban Restoration

watershed stewardsRemoving concrete, asphalt and other impervious surfaces allows stormwater to infiltrate into the soil, reducing flooding and sewer overflows and increasing the steady flow of cool ground water into streams during warm, dry periods. Depaved sites are converted into community gardens or stormwater management facilities.

  • King Neighborhood Association “Green King”
  • Beach School Stormwater Gardens
  • St.Francis Catholic School Courtyard

On-site stormwater management using green infrastructure is vital to Portland's watershed health. These projects on developed sites include anything from swales and disconnected downspouts to pervious pavers.

  • Tabor Commons Stormwater Shelter
  • Bridger Water Garden Downspout Disconnection
  • Heart of Wisdom Rain Garden

Natural Area Restoration

Removing invasive plants and restoring native plants improves wildlife habitat and maintains natural food webs. Participants in natural area restoration projects learn about watershed health and discover places to enjoy nature.

  • Tryon Creek Watershed Restoration Mentors
  • Friends of Tideman-Johnson
  • Friends of Crystal Springs

Community Gardens

Creating community gardens can involve pavement removal, soil improvements, erosion control, and invasive plant removal. Community gardens can include edible native plant areas, native plant areas for pollinators, rain gardens, fruit and nut trees and can provide watershed education opportunities.

  • Metropolitan Family Services, David Douglas High School Community Garden
  • Glenfair Church, Glenfair Community Garden
  • Muslim Community Center of Portland, Seeds of Understanding

Cleanup Projects

Removing trash from natural areas and waterways benefits local wildlife and water quality, and transforms neglected places into community assets.

  • Our Happy Block Watershed Project


These vegetated roof systems replace conventional roofs. Ecoroofs collect, filter and evaporate rainfall to reduce stormwater runoff while improving urban heat island effects and providing habitat.
