Land Acquisition

Public ownership of natural areas protects them from development and allows restoration of sensitive habitat, especially around the headwaters of streams and riparian areas. Healthy natural areas provide places for wildlife to live in the city, protect rivers and streams and prevent flooding, erosion and landslides.

Ecoroofs

Ecoroofs manage stormwater on-site before it flows over streets and washes pollutants into streams or the sewer system. Ecoroofs are living, breathing, sustainable alternatives to conventional roofs. They improve air quality, provide habitat for pollinating insects and birds, save energy, reduce the urban heat island effect and provide more neighborhood green spaces.

Revegetation

Restoring native plants and trees in natural areas and open spaces provides healthy habitat and better water filtration. Revegetation makes urban forests more fire-resistant and better able to adapt to climate changes. Regular natural area maintenance costs less than restoring degraded land, and creates healthy natural areas for future generations.

Culvert Replacement

Many old culverts under roads don't allow migrating fish to pass through, and can cause flooding and erosion during heavy rains. Replacing them with culverts designed to allow fish to pass through makes more habitat accessible to native fish like coho salmon. It also restores a more natural stream flow that helps the ecosystem and protects property.

Green Streets

Green street facilities manage stormwater runoff naturally, allowing water to soak back into the ground and keeping pollutants out of rivers and streams. This is more cost-effective than piping stormwater to a treatment plant and uses less energy. Green streets recharge groundwater to supply cool, clean water to rivers and streams. They also add natural beauty to neighborhoods and can help calm traffic. Click here for more information about green streets. 

Trees

Trees hold water to reduce stormwater runoff, as well as filtering air pullutants and providing bird habitat. Trees stabilize soil to prevent erosion, provide shade and absorb carbon to reduce the greenhouse gases that contribute to climate change. Trees improve property values, and street trees can slow traffic, making streets safer for pedestrians, bike riders and motorists. Click here to find out more about tree planting. 

Invasives Removal

Early detection and removal of new invasive plant species prevents major infestations in Portland. Education and outreach limits the introduction of new invasive species that threaten our native ecosystem. Ongoing maintenance keeps parks, yards, forests and streambanks healthy.
