FREE Rain Garden and Native Plant Workshops

0 Comments | Add a Comment

East Multnomah County Soil and Water Conservation District is offering another series of workshops for Portland homeowners

Every year, the staff at East Multnomah County Soil & Water Conservation District (EMSWCD) provide FREE rain garden and nature education classes across Portland. From the EMSWCD website:

Perfect for all levels of do-it-yourselfers, our FREE workshops highlight landscaping with native plants, water conservation, creative stormwater solutions and chemical-free gardening techniques that are good for people, water and wildlife. Most include a field trip to a neighborhood project or garden to see these principals in action.

This year Environmental Services and the Sunnyside Neighborhood Association will host a series of these workshops for residents of neighborhoods where managing stormwater on private property is an important part of current sewer rehabilitation projects.

Urban apartments can have nature, too

Environmental Services works with property owners in targeted areas in Portland to install rain gardens that help relieve local sewer problems.

A recent project in the Sunnyside neighborhood near SE 28th Avenue and Salmon Street removed about 500 square feet of asphalt and turned a bleak, urban courtyard area into a community asset. A rain garden, drywell, and patio made with pervious pavers replaced the asphalt area.

Now runoff from roof and paved areas soaks into the ground to keep stormwater runoff out of the sewer system, and apartment tenants have a natural, outdoor space to enjoy.

It was important to the property owner to plant a mix of native species to create habitat for beneficial pollinators and birds. The project directs runoff from 4,350 square feet of roof and paved area to the rain garden, and the 200 square foot patio lets rain soak through its pervious pavers into the ground to reduce stormwater runoff.

The rain garden keeps over 100,000 gallons of stormwater out of the sewer system every year to help reduce sewer backups, replenish groundwater and improve watershed health.  

Environmental Services uses partnerships like this to solve sewer capacity issues in neighborhoods with old, undersized pipes. These partnerships also save money for Portland sewer ratepayers by reducing sewer maintenance and wastewater treatment costs.

River View Natural Area Plan Adopted


Protecting the natural resources and planning for future trails

On January 14, 2016, the Portland City Council voted unanimously to adopt the River View Natural Area Management Plan.  

The plan protects this valuable 146-acre natural area in southwest Portland, uses a science-based approach to direct management priorities, and outlines a public access strategy that is compatible with protecting natural resources.

In 2011, Environmental Services, Portland Parks & Recreation, Metro and the Trust for Public Land purchased the site from River View Cemetery to protect the natural area’s water quality, habitat and wildlife.  River View is part of the Westside Wildlife Corridor that runs through the West Hills from Forest Park to Tyron Creek State Natural Area.

River View’s seven streams and multiple wetlands provide clean, cool water to the Willamette River.  Water temperatures in the river are too high for salmon and other native fish, but river water can be up to 10 degrees cooler at Powers Marine Park where River View’s streams enter the Willamette.  Protecting these cool water sources helps Portland comply with water quality regulations and support salmon recovery.


Since acquiring the property, restoration projects have removed invasive vegetation and planted more than 75,000 native trees and shrubs. See photos from some of the restoration work in our past blog post.   

The full plan and more information about the planning process and public involvement are posted on the Parks website. The city will begin implementing the plan this spring.

City Bureaus Devise Plan for Street Improvements in Southwest Portland

0 Comments | Add a Comment

The Tryon-Stephens Headwaters Neighborhood Street Plan will be a guide for street improvements that include appropriate stormwater management techniques

The Portland City Council unanimously adopted the Tryon-Stephens Headwaters Neighborhood Street Plan in November. With this plan, new neighborhood streets will have smaller footprints than traditional streets, which means they won’t generate as much stormwater runoff. The plan will be a guide for street improvements that include appropriate stormwater management techniques. This will allow neighbors, developers, and the city to improve streets and stormwater management more economically and without changing the feel of the street.

The Tryon-Stephens Plan:

  • Is the first collaboration between the Portland Bureau of Transportation and the Bureau of Environmental Services at the neighborhood scale
  • Furthers the application of new street and stormwater designs that are more flexible and more affordable than the traditional street and stormwater designs that were the only option until a few years ago
  • Moves beyond a one-size-fits-all approach to put improvements on local streets within reach for property owners and the city
  • Lays the foundation for cross-bureau collaboration and for thinking about street and stormwater infrastructure

Go to for more about the Tryon-Stephens Plan, including a link to the final report.

Portlandness: A Cultural Atlas


New book challenges your views of Portland’s neighborhoods and landscapes

Portlandess book coverPortlandness: A Cultural Atlas, a new book by PSU professors David Banis and Hunter Shobe, is a fresh look at the city for lovers of Portland’s environments.

Chapters include everything from the Columbia Slough and Oaks Bottom to urban wildlife, zoning, demographics, lost streams, ecoroofs and rain gardens, foodie and biking culture, and transportation.  It is infused with photos and stories of Portland’s green infrastructure, including some Environmental Services projects. 

There is something for everyone, whether you’re a newcomer or long-time Portlander.  The book’s innovative graphics and maps were created both by professionals and students (including third graders), and reveal the city’s various cultures and attitudes. We recommend it for the curious, map geeks, and fans of coyotes and chickens!
