The Electrification Movement Is Spreading Across Oregon

April 2024

It’s Clean, It’s Quiet, It’s Healthy

Electrify Your Landscaping and Healthy Yard Care

The Lake Oswego Sustainability Network is launching a campaign to support healthy yard care practices and the transition away from gas-powered landscaping equipment (GPLE). Gas-powered landscaping equipment causes significant air and noise pollution that negatively impacts workers, neighborhoods, habitat, and health of the soil.

The campaign will contribute to the achievement of the City’s Sustainability and Climate Action Plan goals by supporting the reduction of air and noise pollution in the community. It will include citywide mailers, newsletters, social media, website informational content, letter writing campaigns, and public events.

Reasons to Eliminate the Use of Gas-Powered Landscaping Equipment

Gas-powered landscaping equipment is responsible for significant air and noise pollution. Operators of this equipment can be particularly affected. Many types of hand-held landscaping equipment use 2-stroke engines, which are the worst offenders.

Gas-Powered Leaf Blowers

EXTREME NOISE

Because it is low-frequency and high-decibel, the noise of a gas-powered blower is significantly louder than an electric one. It permeates walls and negatively impacts up to 90 surrounding homes. The noise contributes to hearing loss, hypertension, and stress.

HEALTH RISKS

2-stroke engines burn a mixture of gasoline and oil, and they produce exhaust fumes laden with high levels of benzene, butadiene, formaldehyde, and fine particulates, all of which are known carcinogens and associated with respiratory, cardiovascular, and neurological harm.

ENVIRONMENTAL HAZARDS

Their toxic waste and smog-forming emissions harm ecosystems and contribute to the climate crisis. Gas leaf blowers create up to 200-mph wind force which sends dust that can contain pollen, mold, animal feces, heavy metals, and chemicals from herbicides and pesticides into the air.


The Advantages of Electric

Electric landscaping  tools are clean, quiet, safe and convenient. They cost less to operate than their gas counterparts.  Used in conjunction with healthy landscaping practices, they are better for the health of the landscapers, the neighborhood, and the environment.  Today’s electric tools are  powerful enough to handle even the biggest jobs.

Some advantages of electric tools:

  • Instant start: no pulling cords, priming engines etc.
  • Excellent cutting, blowing and trimming power
  • Long run times and easy battery swap outs
  • Multiple tools can use the same batteries
  • No refilling fuel tanks, engine oil and gas cans
  • No replacing spark plugs, air filters and fuel filters

Healthy Yard Care

Using electric yard care equipment is important, but how you use that equipment is even more important.  We need to think of our yards as natural living systems.

These systems include a variety of plants, animals and microorganisms, all working together to promote a robust landscape.

Let’s look at some examples:

Lawn Mowers
It’s great to use a quiet, clean electric lawn mower, but what happens when you follow up with an application of artificial fertilizer?  Organisms in the soil are killed by the chemicals.  The natural process that allows worms and soil microorganisms to flourish and naturally support plant growth is lost.  These organisms are providing natural fertilizers and releasing nutrients that support plant growth.  The natural system is destroyed.

Leaf Blowers
It is great to eliminate the noise, but what happens when all of the leaves are removed from the soil?  That material that feeds the soil is lost and the complex system of insects, worms, and microorganisms is disrupted.  Soil health is severely compromised, and healthy soil means a thriving garden.  So it’s fine to blow leaves off of paths, patios and other hard surfaces, but leave the leaves on the soil and support a healthy natural system in your garden.

Electrifying your landscaping tools is very important – but remember to use those tools in a manner that supports a healthy, sustainable garden.

Sustainable Practices

  • Leave the leaves – leaves and other plant matter under trees and shrubs help build mulch, healthy soil, and habitat for pollinators and wildlife.
  • Grasscycling – leave grass clippings on the lawn or use a mulching mower. Clippings are a natural fertilizer, beneficial for the lawn, and will decompose and disappear quickly.
  • Avoid fertilizer and pesticides – most yards do not need these dangerous chemicals which are harmful to wildlife,  insects, and waterways.
  • Plant care – avoid the use of leaf blowers around plantings as they erode and compact the soil, and damage habitat for beneficial insects and pollinators.
  • Help pollinators – plant native plants and flowers with staggered blooming times, and do not use pesticides.
  • Reduce or replace your lawn – lawns take lots of water and labor to maintain.
  • Reduce the size of your lawn or replace it with plants that take less water and maintenance and provide habitat for insects and birds.
  • Use a broom or rake instead of a gas blower to eliminate massive pollution, dust, and noise. They are more efficient tools than many people think.

Residential Solutions

As residents, there are many things we can do to help with the transition away from gas-powered equipment. We now understand that gas-powered equipment, especially blowers, harms the health and well-being of all. Eliminating their use around your home and your neighborhood alone will have a significant impact.

Ask your landscaper to use rakes and brooms whenever possible to keep the hardscape areas of your home clean.

If your landscaper needs a power assist, ask them to use electric equipment only.

If your landscaper does not have electric equipment, here are ways you can help them make the transition away from gas-powered equipment:

  • Provide your landscape contractor with electric equipment to be used on your property.
  • Offer to share in the cost: Suggest to your landscaper that if they purchase the equipment, you will provide them with the appropriate battery to use on your property, fully charged and waiting for them on your day of service.
  • If your landscape area is relatively small, corded electric equipment might be a good solution; extension cords and an exterior outlet eliminate the need for charging batteries.
  • Adopt-a-landscaper: If your landscaper services other properties in your area, consider sharing the cost among neighbors.

Residential Landscapers

Many landscaping services in our region already offer electric services. A story from Oswego Yard Care shows why businesses are moving towards this model:

Dan Fidler and Lonny Chavez started Oswego Yard Care in 2019 with the desire to create a landscaping business using quiet renewable energy. They use all-electric battery-powered Ego brand tools that greatly reduce noise pollution and have no gas fumes. Every kWh of energy they use to recharge their equipment is offset with the purchase of clean renewable energy. They have enthusiasm for innovation and insistence on clean energy. Oswego Yard Care maintains and creates beautiful yards by combining seasonal color, native plants, and perennials. Dan and Lonny encourage other landscapers to check out their equipment to experience for themselves how great this electric equipment works. Visit oswegoyard.com for more information.

What the City of Lake Oswego is Doing

The City of Lake Oswego has already taken important steps to eliminate gas-powered equipment from its contracted landscape services for 200 city-owned sites and has replaced much of the gas-powered equipment used by Parks and Public Works.

Parks and Recreation

Jeff Munro, Deputy Director

The Parks Department’s transition to electric tools aligns with our dedication to maintaining beautiful parks while being kind to our earth and environment. We have added all types of electric equipment including blowers, hedge trimmers, chainsaws, push mowers, riding mowers, utility vehicles, and a new Ford F-150 that can power up equipment in the field. Our Parks Multiple Site Landscape Contract also requires that the contractor that maintains some of our facilities & parks only use electric equipment to perform their maintenance tasks.

Our commitment to Sustainability is powering our parks with electric tools and vehicles that reduce emissions and minimize our carbon footprint.  The Parks Department will continue to integrate this electric initiative into daily practice and continue to source new equipment and battery types along with continuing with the City Council’s goals on climate and sustainability practices with fleet policies.

Public Works

The Public Works Department has had an electric contract with STORM Landscape Services since 2021.

STORM Landscape Services is a commercial landscape company that has 6 crews that are all electric. In a recent interview, Randy Mihaldo shared details about his work with the City and his transition to electric landscaping equipment. Read the full story…


Transitioning to Electric Landscaping Equipment: A Case Study with Mountain Park HOA

Tod Blankenship, Director of Landscape Stewardship

I personally have been researching and purchasing small battery equipment for over 10 years. When I was with the City of Wilsonville, I began spearheading a transition to Stihl battery-powered small equipment. Stihl has long been a champion of landscape equipment. When it comes to committing to battery-powered equipment there are many factors to be considered beyond the craftsmanship and reliability of the tool itself. It is also a commitment to batteries and chargers. Stihl has been at the forefront of battery technology, and it was an easy decision for us.

MPHOA Landscape Stewardship Division has purchased nearly all of the Stihl commercial battery-powered tools available. When it comes to the replacement of any light equipment we will purchase a battery option if available. We have found most of the items suit our needs as long as we have plenty of extra batteries. The disappointment has been the limited backpack blower options.  A new Stihl electric backpack blower is now available and we plan on buying 5 additional blowers this year.  We have also purchased (2) Westward electric low-speed vehicles for use on the road and throughout our 9 miles of trails.


Portland Ban on Gas-Powered Leaf Blowers

On March 13, 2024, Portland City Council unanimously passed an ordinance phasing out gas-powered leaf blowers citywide. (2-minute video of the 5-0 decision) Starting January 1, 2026, gas blowers will be prohibited for 9 months of the year (Jan-Sep). A full year-round ban will begin on January 1, 2028.

Portland is the second largest city to adopt such an ordinance, behind only Washington, D.C. This ban complements the steps being taken by Multnomah County to transition county leaf blower use to electric before 2025, and the city of Portland’s effort to switch out their stock of gas-powered leaf blowers for quieter and cleaner electric models. It is overwhelmingly clear that the public is asking for gas leaf blowers to be phased out.  When public comments were solicited by the city of Portland, 86% of the 786 commenters supported a prohibition of gas leaf blowers and only 11% opposed it in any way.

Quiet Clean PDX was instrumental in the passage of the Portland ordinance to ban gas-powered leaf blowers. QC/PDX is a Portland based volunteer organization that has been working since 2018 to phase out gas-powered leaf blowers.  They have raised awareness of the dangers of gas leaf blowers, advocated for their elimination, and promoted healthier alternatives.


American Green Zone Alliance


American Green Zone Alliance (AGZA) is a national leader in low-impact, low-noise landscape solutions. They offer education and training, and they work extensively to field test and certify electric equipment.

In 2021 LOSN partnered with Dan Mabe, founder of AGZA to host an online forum (see link to the forum below). He discussed the air and noise pollution issues with gas-powered equipment, the electric equipment that is available, the cost comparison between gas and electric, and the return on investment. He also discussed what other communities with similar seasons are doing to transition to electric.

In November 2023, AGZA partnered with the National Association of Landscape Professionals (NALP) and the Oregon Landscape Contractors Association (OCLA) to put on a Gas to Electric Symposium on the Nike Campus. Topics included current regulations, low-impact landscape maintenance and operations, funding mechanisms to lower the cost of battery-powered equipment, and commercial equipment demonstrations.

Electrify LO Joins Electrify Oregon

Electrify LO has now joined other Electrify organizations in towns throughout our state in the network “Electrify Oregon.” This month, these 16 organizations launched a combined website  with information on the basics of an energy-efficient household and how to find contractors and financial incentives to help you electrify. The website is focused on guiding homeowners toward becoming more energy-efficient and climate-friendly in multiple ways.

Electrifying your Life is Climate Action

Over the last year, the LOSN “Electrify LO” campaign has promoted the importance of moving away from fossil fuels toward electrification of vehicles and homes as among the most important ways we can reduce our carbon footprint and address the climate crisis. Now we can dive into when and how to electrify with information on financial incentives for home electrification and electric vehicles, how to choose a contractor for heat pumps for space conditioning, and how to try out an induction cooktop.

What Incentives Are Available Now? What Other Incentives Are Coming?

On January 1, 2023, new tax credits became available for many home electrification and energy efficiency projects including weatherization, heat pump water heaters, heat pumps for space heating and cooling, electrical panel upgrades, rooftop solar and home battery storage systems.

Later this year (or early 2024) additional upfront discounts (also called rebates) will become available for these improvements for lower-income and some middle-income families. The discounts, which can be combined with the tax credits, can be additionally used for induction and electric stoves, new wiring, and heat pump clothes dryers.

One more discount, available at all income levels, is called a whole home energy reduction rebate and it rewards homeowners for overall energy use reductions.

Inflation Reduction Act 2022

What to expect for the rollout of the Inflation Reduction Act of 2022 – a thoughtful analysis from Energy Trust of Oregon.

The Inflation Reduction Act is expected to help millions of Americans benefit from energy efficiency and renewable energy. But exactly when and how a lot of those benefits will be rolled out is still unclear.

Because of how the legislation was passed, there are a lot of details that still need to be determined, including rebate and tax credit amounts and the specific equipment that will be covered.

Plus, as the largest U.S. investment in climate and clean energy, it’s going to take time for all that money to reach customers and communities, and some programs aren’t expected to roll out until 2024.

Watch the Electrify LO page for updated information.

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).

Get Your Heat Pump Air-Conditioner Installed Before the Summer Heat

In 2018, 30% percent of homes in Oregon had no air conditioning. Hot summers, including the heat dome of June 2021 that produced temperatures in Lake Oswego higher than 112 degrees F, have led to an upswing in interest in indoor cooling. 

Heat pumps are a great way to cool your home in the summer. This same heat pump will also warm your home in the winter–it can either replace your furnace or dramatically reduce its use. Heat pumps are 2-3 times more energy efficient than traditional furnaces, so produce fewer greenhouse gas emissions and cost less to operate.

Portland General Electric has a list of approved contractors for heat pumps and offers discounts of up to $1700 through June 30.  

Our partner Electrify Now also has a list of trusted contractors that offer discounts. 

Energy Trust of Oregon has information on ways to finance heat pumps—instead of a large upfront cost to purchase the system, a monthly charge will be added to your PGE bill.

If you want to get the benefit of a cooling system that also provides heat during the winter, lower operational costs, and the lowest impact on the environment, install a heat pump.

Luscher Farm Summer CSA is starting in May!

When: Starting May 19th through October 27th
Pickup Location:  Luscher Farm City Park, 125 Rosemont Rd, Lake Oswego, OR (map)
For more info and to join today click here.

If you join now, you will enjoy the bounty of healthy, fresh vegetables direct from the farm for the whole summer growing season.

The Luscher Farm CSA has been a partner for many years and is a program of Lake Oswego Parks & Rec that is managed by the 47th Ave Farm. 

Community Supported Agriculture (CSA) is a partnership between a farmer and local families who invest in each other. Members pay at the beginning of the growing season and in return, you will receive delicious local produce all through the summer season. Harvest starts mid-May and continues through the end of October. Members come to Luscher Farm on Thursday evenings to pick up their beautiful bountiful basket of produce.

In addition to growing great vegetables, the CSA farmers are also using many different practices to increase sustainability at Luscher Farm. To cultivate and weed our fields, we use both electric tractors and draft horses. This reduces dependence on fossil fuels and runs lighter on the ground than traditional diesel tractors. We are also innovating with different cover crop mixes between our year-round vegetable crops. Cover crops can increase carbon sequestration, improve soil health, provide habitat for beneficial insects and reduce the need for off-farm inputs. All of these practices add up to more sustainable & delicious veggies for your family!

Now is the time to sign up for the Summer CSA program
