Welcome Home to Vanport


Hike, Bike, Listen, Learn at the Vanport Mosaic Festival this weekend

aerial view of 1948 Vanport Flood Every year in May, we remember the catastrophic flood of 1948 that destroyed the community of Vanport in North Portland.  Vanport housed 100,000 people, but disappeared when the Columbia River and Columbia Slough flooded.  It’s a reminder of how nature shapes our communities and history. 

This weekend, check out the Vanport Mosaic Festival for film screenings, theater, tours and more. 

On Monday, May 30, join the Welcome Home to Vanport activities and tour.

The day includes a self-guided walk or bike tour, speakers and exhibits at Portland International Raceway, part of historic Vanport city. You can hear from historians, a Kaiser family member and former Vanport residents.

May 30, Memorial Day, 10:00 am - 3:00 pm

Portland International Raceway, 1940 N. Victory Blvd

Portland's Tree Planting: Actions for Equity


new trees along street with no curb

(post edited on May 25, 2016 for factual correction)

Since 2008, Environmental Services’ Tree Program has planted over 40,000 new trees along the streets, in yards and other Portland neighborhood spots. From the start, efforts have focused on outreach to plant street trees in low-canopy, low-income neighborhoods, which are also some of Portland’s more racially diverse communities.

The effort to plant trees in underserved neighborhoods is often impeded by lack of planting strips and by unimproved frontages – streets without sidewalks or sometimes without curbs.

The increased tree canopy cover where it is most needed helps provide all residents with long-term benefits such as improved air quality and stormwater management, lower summer temperatures, and better health outcomes.

Endangered Species Day


Portlanders' work for clean rivers and streams helps threatened and endangered species in our area

It's Endangered Species Day - a good day to reflect on all the things we do in Portland to protect and restore our native fish and wildlife habitat. In Portland, 15 fish species are listed under the Endangered Species Act.  Listed salmon and steelhead are found in 127 miles of Portland’s rivers and streams.  Learn more about the issues and what we’re doing here.

Check out this video of a project Environmental Services​ did last year to improve habitat and water quality for juvenile salmon that take refuge in the Lower Columbia Slough as they migrate. The log jams are upstream of Kelley Point Park.

Tree planting at Lincoln Park Elementary

This spring, staff from the Environmental Services Tree Program spent the afternoon with Lincoln Park Elementary students planting seven trees on the school’s property. The 30 students are members of the Schools Uniting Neighborhoods (SUN) after school gardening program and had the opportunity to not only have fun getting their hands dirty, but also learn about the trees and how they will benefit their school.

The group planted two cork oaks, two Jefferson elms, two big leaf maples, and a western red cedar. Some of the trees even got new names from the students: Snowcone, Awesome Tree, and Kevin.

The focus of the planting was to beautify the grounds and provide access to an ongoing learning opportunity for the students, and to provide much needed shade for south-facing classrooms. The trees will also provide shade for students at recess, habitat for wildlife, stormwater management, and—as one recent study has shown—may help reduce student stress levels and improve concentration.

The local contractor Treecology will water and prune the trees for the next few years to ensure they are well established and provide benefits for generations of Lincoln Park Elementary students to come. Treecology also sourced the trees and helped the group plant.

Biking for healthy rivers and streams


bike commuter group

This week, some Environmental Services staff teamed up on their morning bike commute as part of May’s Bike More Challenge. Fish hats made their debut in anticipation of Sunday Parkways, as well as a few super hero accessories.

Environmental Services champions the Bike More Challenge because human-powered transportation is good for Portland’s rivers and streams. Stormwater runoff from roads carries lots of nasty pollution from cars and other vehicles into our waterways. Fewer car trips means less pollution in our air and water.
