Saturday, November 4th from 9 am to Noon
Mountain Park Clubhouse – Hawthorn Room
2 Mt. Jefferson Terrace,  Lake Oswego

The LO Tree Summit is held annually as a forum for people to gather together to increase their arboreal knowledge, discuss the importance of a healthy, interconnected urban ecological system, and share opportunities to maintain the health of the urban forest.


Keynote Speaker: Scott Altenhoff, Urban and Community Forester, Oregon Department of Forestry.  Scott will speak on the unique character of the Lake Oswego urban forest and its complex habitats, as well as the intrinsic relationship people have with the health of an urban ecosystem.

LO Tree Summit is presented by the Oswego Lake Watershed Council
in partnership with the Lake Oswego Sustainability Network.


Mary’s Garden

We recently lost Mary Ratcliff, one of the founding LOSN board members. Upon hearing of her death, John Movius with Terraccord Landscapes shared with us:

Mary was a longtime landscaping client who became a friend. She realized her vision of transforming her yard into a sanctuary for native plants and wildlife. She was a steward of the 150 year old Heritage Elm tree on her land, and the miner bee colony living deep beneath the soil outside her house. Her enthusiasm and curious spirit made working with her a joy. Mary was generous with her knowledge of bird life around her and would often pause while talking because she heard a call from near or far, which would allow us both to listen more closely in the moment. I had the opportunity to see over the years of working on her garden, how much joy she found in the natural world, and how much she liked to share laughter and wonder. I will always appreciate the trust she put in me to help her restore her landscape, which was part of a property that had a long history for herself and her family. We will deeply miss you, Mary.”

Mary’s garden is the epitome of what it means to Leave the Leaves. She had a deep appreciation of our interconnectedness within a natural environment. When the leaves fell in the fall, they remained in her garden and were allowed to compost in place. She knew those leaves provide habitat for frogs, salamanders, worms, a wide variety of insects and other invertebrates. That they provide nourishment for fungi and microorganisms that live in the soil. Mary trusted nature!  She understood the importance of allowing natural systems to work together. Her greatest joy was the birds that flocked to her garden to feed on insects, berries and seeds, build nests under bushes and in the trees, and drink a bath in clean water provided by her fountain. Her garden was free of insecticides and herbicides and she never used artificial fertilizers that would interfere with the way nature was thriving under her protection.

Please join us in honoring Mary: trust nature, leave the leaves and avoid using artificial fertilizers or pesticides.


Leave the Leaves…
and other sustainable gardening ideas for fall

Leave the Leaves:

  • If they fall in garden beds let them stay in place

  • If they fall on your lawn use an electric lawn mower to chop them up and let them stay in place

  • If they land on your driveway, patio or walks leave them for a while and let the wind blow them off.  Leaves that are not removed by the wind can be raked, swept or blown with an electric blower into your flower beds or onto your lawn before you chop them up with the mower.

By spring, all of the leaves will disintegrate into a leaf duff, which is just another name for natural compost. Some will even be pulled underground by earthworms.

Leave the flowers:

  • Birds will come to eat the seeds.

  • Wait until early spring to cut back your perennials to maximize winter food for birds and small mammals.

Leave the berries and other fruit on shrubs and trees.

Leave small branches and twigs – they provide good food for fungi. They will also disintegrate into the leaf duff.

Save yourself a lot of work and Leave the Leaves!

Electrify Your Landscaping

One of LOSN’s projects is working with others in our community and region to switch from gas powered landscaping equipment to electric landscaping equipment. Gas powered landscaping equipment causes significant air and noise pollution that negatively affects the workers, neighborhoods, habitat and health of the soil. Electric landscaping equipment is readily available and works great!

Communities all over the United States are targeting gas powered landscaping equipment in response to the significant noise and air pollution they produce.

The benefits of switching to electric landscaping equipment helps to significantly reduce carbon emissions and has major benefits for the well-being of our community.

Get more information from Electrify Now on the advantages of all electric landscaping equipment and healthy yard care.

For more information and resources check out the LOSN page on Electric LandscapingAmerican Green Zone Alliance is also a great resource. They are a leader in low-impact low-noise landscape solutions and does excellent work helping landscapers and communities transition to electric landscaping equipment.

A local volunteer organization, Quiet Clean PDX, is working to educate and offer solutions to eliminate gas powered leaf blowers.

Sustainability in the City

January 2023


Embedding Sustainability in the City

The City of Lake Oswego embeds sustainability in their strategies and operations following a number of paths including making a significant investment through:

  • Prioritizing sustainability initiatives in the City Council Goals for the year.
  • Staffing a full-time Sustainability Program Manager position.
  • Commissioning a citizen’s advisory board on Sustainability.

We’d like to share with you the goals for each of these areas for 2023.


City Council Goals for 2023

The city councilors just completed a full-day goal setting retreat Saturday, January 21st, where they gathered feedback and suggestions from citizens of Lake Oswego, a number of community groups and the various boards and commissions and other stakeholders to come up with a prioritized list of initiatives under eight major goals.

For each of eight areas, they reviewed the proposed goal language and discussed the specific initiatives related to each area. They started with 40 initiatives, several which were carried over from the previous year. Their task was to prioritize the top 15 to 20 initiatives which will direct how they (and the city government) spend their time this year.

On Feb. 7, the council will vote to approve their goals for the year. (Approved goals will be available on this page after approval.)


Below are the eight areas and proposed goal language.

Climate Action. Combat climate change and strengthen the community’s resilience to climate impact.

Parks, Natural Areas, & Recreation. Invest in Lake Oswego’s high-quality parks, natural areas and recreational amenities.

Diversity, Equity, & Inclusion. Foster a welcoming and inclusive community where all people have the opportunity to thrive and have equitable access to City services.

Transportation. Improve transportation connections, mobility and safety for all travelers and all types of trips in Lake Oswego.

City Operations. Strengthen public trust in the City through continuous improvement outstanding customer service, infrastructure investments, and fiscal stewardship.

Economic Development. Support business development and job creation in Lake Oswego.

Community Development. Conserve the community’s character, sense of place and quality of life by planning for change and growth.

Public Safety. Ensure a safe, secure and prepared community.


Many of the specific initiatives are directly related to sustainability. Two initiatives under Climate Action received unanimous support:

  1. Integrate climate action and resilience into City projects such as capital improvement planning, housing policy, and City facilities and fleet decisions.
  2. Update the Urban and Community Forest Plan using the findings of the 2022 State of the Urban Forest Report. Address issues related to equitable outcomes, tree species, and climate change.

Other sustainability-related initiatives that maybe be adopted include:

  • Make a financially and environmentally responsible long-term investment in a wastewater treatment plant.
  • Continue construction of sidewalks and pathways focusing on safe routes to school.
  • Continue to work on key housing initiatives and housing production strategy.
  • Implement community policing recommendations.
  • Create disaster preparedness processes and plans in collaboration with the community.

LOSN submitted input to the goal setting session. See details at this link. Although not all our initiatives made the top priority list, the two Climate Action initiatives listed above are strong endorsements of support for sustainability. In addition, a progress report on the Climate Action plan is already part of staff’s work plan.


City of Lake Oswego’s Sustainability Program Manager

Amanda Watson has been the city’s full-time Sustainability Program Manager for the past year and a half and provides a wealth of expertise and guidance to the city and the community. She is responsible for implementing the City’s Sustainability and Climate Action Plan in collaboration with other city departments and community groups. She also manages the City’s solid waste and recycling franchise with Republic Services.

Amanda serves as staff liaison to the Sustainability Advisory Board (SAB). Buzz Chandler, Co-Chair for the SAB, says, “As one of the Co-Chairs of the LO SAB, I work very closely with Amanda, in her role as Sustainability Program Manager for the City, and she has helped elevate our Board to becoming an ever more effective and forward-thinking advisory body for the City.  She always has a big smile, is very knowledgeable and most importantly works tirelessly at helping us manage and achieve our goals for the Board every year. She is a truly fine example of the high quality and character of LO City Staffers. We as a Board and as a City are fortunate to have her.”

Amanda has also proven to be a great partner for LOSN in promoting sustainability. Duke Castle provides a LOSN perspective, “Amanda is great sustainability advocate. She is well versed in the triple bottom line concept and has a good understanding of sustainability issues both within the city and out of it. She is a real pleasure to work with because she is so collaborative and open to the variety of ideas we bring to her.”

Amanda led the collaborative effort for putting on the first Lake Oswego Sustainability Resource Fair last year and will be helping again this year (April 15, 2023 – check the events section for more) for what has become a terrific annual event full of resources for Lake Oswego residents.

In addition to her support on the Council and SAB’s goals, she will be focused on:

  • Completing a progress report on the Sustainability and Climate Action Plan.
  • Increasing use and availability of clean energy in Lake Oswego, including sharing information with community members and businesses about available financial incentives and programs for clean energy and energy efficiency.
  • Website improvements for the EcoHome LO residential sustainability certification program that launched last year.

City of Lake Oswego’s Sustainability Advisory Board

The Sustainability Advisory Board (SAB) is a citizen advisory body appointed by the City Council to provide advice, citizen perspective, and expertise on issues relating to sustainability. Consisting of 7 members with staggered 3-year terms and 2 youth members with 1-year terms, these citizens promote a sustainable economic and ecological quality of life in our community. This year, their goals are:

  • Advance the adoption of electric vehicles.
  • Develop recommendations to the City Council for a ban on the sale and use of gas-powered landscaping equipment in Lake Oswego.
  • Continue progress on climate mitigation and resilience planning and implementation.
  • Expand outreach and engagement to enhance the sustainability of the city as a whole.

The full goals with the planned initiatives can be found here.

LOSN partners with SAB in many areas including the annual EV Fair, promoting the transition to electric landscaping equipment, collaboration on goal setting, and the annual Lake Oswego Sustainability Resource Fair.

Here are some ways you can get involved with SAB if you want to work with the city on sustainability and/or climate action:

  • Attend an SAB meeting. (Meetings are the 3rd Monday of the month, 6:30 pm to 8:30 pm. Check the LOSN calendar for more information.)
  • Provide public comment at a meeting.
  • Apply to be a member of the board. (Applications are open in the April-May time frame at this link).

Nov 17: Beyond Net Zero, Restorative Buildings: the PAE Story

PAE Headquarters

What if a building was not just sustainable but restorative, a building that put back more than it takes?

That is the goal of the Living Building Challenge, a concept introduced on 2009, where its end goal “is to encourage the creation of a regenerative built environment. The challenge is an attempt to raise the bar for building standards from doing less harm to contributing positively to the environment.”

This is an approach that goes way beyond the LEED rating system focusing not only on net zero energy but also net zero water and waste.

One of the leaders in implementing this concept is Portland based PAE Consulting Engineers. They have eleven projects designed to meet this rigorous framework. The latest is their new headquarters here in Portland, a five story building which is set to be the world’s first developer-driven Living Building.

When: Wednesday, Nov 17,  2021
Time:  6:30 pm – 8:00 pm
Where:  online via Zoom
Speakers: PAE president Paul Schwer will be joined by PAE associate Karina Hershberg to tell the story of how their building was able to reach this goal while simultaneously providing a return for their investors.
