A Historic PartnerhipRemembeRing 20 yeARs in pARtneRship with smUD

From the Desk of the executive Director

Ray Tretheway, Executive Director, Sacramento Tree Foundation

This October marks the 20th anniversary of the founding of the energy-saving shade-tree partnership between the Sacramento Municipal Utility District (SMUD), their residential rate-payers, and the Sacramento Tree Foundation. This popular program reflects the ideals of both organizations:

smUD’s vision is to empower its customers with solutions and options that increase energy efficiency, protect the environment, reduce global warming, and lower the cost to serve our region.

the purpose of the sacramento tree Foundation is to grow healthy, livable communities in the sacramento region by empowering people to plant, protect, and learn about trees.

I recall riding to SMUD in the spring of 1990 with then Tree Foundation Board President Bill Fobes to meet S. David Freeman, the new general manager of SMUD. Winston Ashizawa, program manager at SMUD, had called the meeting to discuss what role SMUD could play in the Tree Foundation’s recently announced one million tree campaign - Trees for Tomorrow. Trees for Tomorrow was a spirited coalition of business, civic, and government leaders dedicated to restoring Sacramento’s bountiful tree legacy. Over the following decade this campaign was successful, thanks in large part to SMUD’s participation, and culminated in a festive Millennium Tree Celebration in downtown Sacramento.

At the initial meeting Mr. Freeman talked about energy efficiency, demand-side management, and his intention to plant half of the one million tree goal. He talked about the utility’s investment in an urban forest dedicated to energy efficiency. We also talked about investing in education for citizen action and environmental stewardship to benefit the greater community.

Stories abound of this unlikely three-way utility-nonprofit-community partnership that continues to attract as much attention today as it did 20 years ago.

One story I recall in the first year of the program was the reluctance of the residents of a senior mobile home park to join the free shade tree program due to the belief that they wouldn’t be there to enjoy the shade. We returned three years after their planting event to find them enjoying trees that measured 18 to 21 feet in height and towered over their roof tops.

There are many touching tales from the 150,000 shade tree planters who recall the hours it took to dig one tree hole and how the whole process was like an adoption. They still enjoy taking yearly pictures to document the growth of both their children and their trees.

A 20th anniversary may be seen in tree terms as a minor celebration when trees in Sacramento are known to grow for 80 to 100 plus years, however every urban or suburban tree needs a dedicated friend to survive and thrive. Please share your shade tree story with us at [email protected].

Picture nearly 500,000 trees operating as nature’s power plant to cut back on the costly energy needed to run a community’s air conditioning needs on its hottest summer days.

Picture over 150,000 people that are willing and trained to run that shady phantom power plant.

Fast forward 40 years and this shady asset planted to avoid energy costs combines with other benefits to the community to make a total calculated net benefit of almost $30 million.

Levee Advocacykeeping tRees on oUR Levees

T he Army Corps of Engineers has published nationwide guidelines that require all trees and other vegetation be removed from levees. Removal of vegetation is required in order to provide “a reliable corridor of access” for vehicles and equipment and to prevent water from seeping through levees along root systems. California has 1,600 miles of levees that fall under the Army Corps’ area of supervision – 400 miles in urban areas and 1,200 in agricultural areas. Urban areas are the focus of more attention with respect to public safety, but Corps guidelines apply to all 1,600 miles. As stated in an April 15, 2010 letter from the California Department of Water Resources (DWR): “The proposed vegetation policy will likely have devastating environmental impacts, as the remnants of the once vast riparian forests and adjacent riverine ecosystems of the Central Valley are now concentrated on the banks and levees of its flood channels.”

Trees improve air and water quality, have incredible benefits for wildlife, increase storm water collection, and reduce temperatures in urban areas. The psychological and physical healing effects we enjoy when walking along rivers under trees must also be considered.

In August the Sacramento Tree Foundation met with over 40 people to discuss the levee issue. We invited representatives from nonprofits, Puget Sound, DWR, and elected officials.

Tim Washburn from the Sacramento Area Flood Control Agency (SAFCA), presented lessons learned while seeking an exemption from the Army Corps to keep waterside vegetation on Natomas levees. The variance was granted because SAFCA was able to design a setback levee, but most other levee systems do not have enough land to use such a design.

Peter Buck, also from SAFCA, explained four research projects investigating risks to levees: Tree Root Architecture, Burrowing Mammals, Windthrow of Trees, and Levee Slope Stability.

Preliminary results for the first three projects show that:1. Tree roots do not grow very deeply into levees

and appear to leave shallow holes. Tree roots will penetrate internal levee walls if cracks are present.

2. Ground squirrels are the most common burrowing animal in the central valley and they do not live in forested habitat. Removal of trees may encourage ground squirrels to burrow in levees.

3. Of 50 trees pulled down, none created root pits that were greater than 3 feet in depth and most were only 2 feet. The second part of the meeting was spent

discussing advocacy. Suggestions were made to speak with federal legislators and the Secretary of the Army as well as taking the issues to President Obama. Since public safety is the most critical concern for the Corps – even though there is no evidence that vegetation on levees has ever caused a levee breach – we discussed how removing trees from levees diverts resources away from other more serious levee problems.

Attendees plan to work together on a group letter and to coordinate meetings with congressional representatives.

We encourage you to get involved by contacting legislators to let them know you oppose the Army Corps guidelines and think more research should be completed before requiring such potentially devastating actions. If you have any questions, please contact Cindy Blain at (916) 924-8733 ext 119 or [email protected].

The Sacramento Tree Foundation is encouraging civic, service and nonprofit organizations to apply for the Citizen Advisory Tree Committee’s (CATC) grant for fall, winter and spring tree plantings. This competitive mini-grant program awards between $1,000 and $15,000 to support qualified tree planting projects on publicly owned property. The goal of this grant program is to increase urban forest awareness and action within the six-county region, including the counties of Yuba, Yolo, El Dorado, Sutter, Sacramento and Placer. Qualifying planting areas include, but may not be limited to public: parks, schools, buildings, cemeteries, trails, and other lands.

The most competitive applications will include a tree planting project, foster community

awareness and education, leverage resources, include community partnerships, clearly explain why the applicant is best suited to succeed with the proposed project, and provide a reasonable project scope and budget.

Applications for CATC funds must be recieved by November 1, 2010 in order to be eligible for review. This unique funding is made possible by a grant from the California Department of Forestry and Fire Protection (CAL FIRE). Applications can be found on our website or by contacting [email protected].

Cash Incentives for Tree Planting

In July of 2010 the Sacramento Tree Foundation along with the USDA Forest Service, Pacific Southwest Research Station’s Center for Urban Forest Research (CUFR) embarked on a project to determine tree growth rates for Sacramento’s ten most predominant tree species. Tree size varies immensely depending

upon location. The data collected will model tree growth using the measurement of trees in different diameter-at-breast height (DBH) classes as a surrogate for growth in Sacramento. The Tree

Foundation will be able to estimate tree height, crown diameter and leaf area based on DBH measurements (the diameter of the trunk of the tree 4.5’ above the ground). This will make it possible to more accurately model the impact trees in the entire Sacramento region have on air quality, energy savings, carbon storage, and rainfall interception.

Using the City of Sacramento’s new street and park tree inventory, the ten most predominant species within the city were identified. Trees were randomly selected in each of eight tree diameter classes, ensuring that measured trees represented all stages of the species’ life cycles, from sapling through maturity. A total of 460 trees were measured and digital photos taken to verify measurements and estimate leaf surface area (important for

estimating air pollutant uptake and rainfall interception). All of the data will be compiled and analyzed by CUFR over the coming months with the resulting tree growth models available within the coming year.

A group of exceptional volunteers worked for 6 weeks collecting data from trees throughout the city. They used altimeters and clinometers to measure tree height, sonar devices to record crown diameters, and digital cameras to capture images for predicting leaf area. They consistently produced very accurate readings. Special recognition goes to Sarah Cannon and Brittany Talbot for each giving more than 120 hours to the project.

20 Years, Nearly 500,000 Trees

stiLL gRowing!

W alk a few blocks anywhere in the urban areas of Sacramento County and you will inevitably pass under the cool shade of a SMUD tree. That is because since the program began in 1990, SMUD has provided our community nearly 500,000 free trees to shade our homes, offices, streets, parks, and schools.

That is a lot of trees, providing a lot of shade. When you stop to think about it, it’s an incredible investment that SMUD has made in our community, with a nearly incalculable impact on our region’s energy consumption, air quality, water, and more.

How is it that Sacramento is so lucky as to have an electric utility that provides free trees? Only a handful of other cities have similar utility-funded programs, and none of them provide trees on the scale that SMUD does.

In the late 1980’s SMUD, in response to concerns about the safety of nuclear power, was trying to figure out how to shut down its nuclear power plant, Rancho Seco. At that moment in

Sacramento’s history, SMUD was faced with the dilemma of having to reduce its overall power production capability at the same time that overall energy consumption was rising in our region. That’s no small problem for an electric utility. In order to solve that problem, SMUD had to think creatively.

The question was how to provide enough energy to all of SMUD’s customers, then and in the future, so that lights would stay on, refrigerators could run, and electricity bills remained affordable. To help answer that question, SMUD turned to the Sacramento Tree Foundation in a unique partnership to plant shade trees. The idea was that, by planting trees to shade homes, people wouldn’t need as much energy to cool their homes during the hot summer months. The beauty of this partnership, whose flagship program was eventually named Sacramento Shade, is that properly located trees provide the most energy saving shade during the afternoon, between 4 and 7 PM. That is precisely

Planting a tree is a great way to

celebrate the 20th anniversary. SMUD

customers are eligible for up to 10

free trees through the Sacramento

Shade program. Call us at (916) 924-8733

the time when Sacramento residents are returning home and cranking up their air conditioners. By no coincidence, that is also the time when the extra power that utilities have to buy is the most expensive and the dirtiest to produce. Thus, by helping its customers to save energy, SMUD could simultaneously avoid producing or buying extra energy from non-renewable sources and help lower individual electric bills.

This October marks the 20th anniversary of the Shade Tree Program, and we’ve been busy. We’ve worked with more than a hundred thousand homeowners, organized thousands of volunteers, planted at hundreds of schools and parks, and educated individuals across the county (and country) about the benefits of trees and how to plant and care for them. In terms of energy savings, we estimate that SMUD has reached a peak-load total reduction (the amount of energy that SMUD doesn’t have to buy or produce when electricity is at its highest demand) of 6.20 MW. That is equivalent to the cooling load of 5,580 homes. In other words, without the Shade Tree Program, SMUD would have to buy or produce enough energy for another 5,580 homes!

To celebrate our success, SMUD and the Tree Foundation planted 40 trees at the Alder Grove community housing center on October 2. We were joined by members of the community who wanted to thank SMUD for their ongoing commitment to making our neighborhoods healthier and more livable.

We will also be spending the next year collecting stories and pictures about the Shade Tree program and its impact. We are looking for before and after pictures, pictures of your tree at planting and how much it has grown, and any commentary you have about what SMUD shade trees mean to you and your community. If you would like to share your story, please email us at [email protected]. Another great way to celebrate the 20th anniversary is to call us to plant a free SMUD shade tree at your home.

And if you have the chance, please take a moment of your time to contact the SMUD Board and staff to thank them for making Sacramento a better place to live.

As we enjoy lush green lawns at our homes, schools and local parks, most of us do not realize that turf grass is the largest irrigated crop in the country, covers over 30 million acres and, on average, accounts for half of household water use. Water use restrictions and high costs are forcing many of us to remove our thirsty lawns to avoid expensive water bills and penalties.

Replacing lawns with low water-use landscapes, known as “Xeriscapes,” is gaining popularity. Xeriscapes combine drought-tolerant plants and efficient irrigation systems to dramatically reduce water use. Trees planted in these areas

further decrease water use by providing shade and lowering temperatures. Xeriscapes can be as beautiful as they are easy to maintain, and your water bill will drop considerably.

The costs in labor and materials to convert to a Xeriscape are recovered through the significant reduction in water use and, most importantly, no more mowing! Do you really need that big lawn? Consider converting to a Xeriscape and spend the weekends enjoying your yard rather than working on it.

I’ve had so many favorite trees that it’s hard to pick just one. I walked dogs in Midtown for 30 years (yes - that long!) and

every single block there has a tree that I looked forward to walking by and under – cork oaks, walnuts, London planes, sweet gum, etc. Midtown is a premier example of the beauty and wonderful environment that an urban forest creates.

But when push comes to shove, my favorite is one planted a ‘mere’ 25 years ago. This London plane tree was planted shortly after David Gibson bought the property that is now our home. Before David put the money down for the lot, he stayed up all night and did a master plan for the house and his office. Based on the master plan, he bought the property and planted the tree shortly afterwards. When the house was built 25 years later, the tree was fully grown and shelters the southern exposure from the summer sun. It is tall enough to shade the second story and we can look out into the upper branches. What a delight and a pleasure!

It’s a particular pleasure because I work from my second story home office much of the week since my departure as a full time principal at Nolte Associates. While I still do contract work for Nolte, I spend much of my office time on the work of the Boards of Directors for the Sacramento Tree Foundation, Valley Vision, ALF, and CADA. And on an entirely different side of my brain and a different part of the house, I spend my time painting abstract canvases. From that office I can see a different set of trees -- including those wonderful valley oaks. How great is that?

My love of trees and the great joy they bring is one of several reasons I joined the board of the Tree Foundation and am so excited to be the new board president. The Tree Foundation rightfully takes pride in the 1.25 million trees that they have played a part in planting over the last 28 years, and the campaign to plant 5 million more in the region by 2025 is such a worthy goal that the entire board is excited and enthused about pursuing that goal and vision. And the staff is such an excellent one! Truly people that are devoted to trees and all their benefits to livable communities: energy savings, carbon sequestration, greenhouse gas reduction, air and water quality improvements, public health... the benefits are so numerous! I want everyone in the Sacramento region to be as enthused as we are about seeing these goals get met!

1. Inspect trees for strong branch attachment. Remove broken or dead branches at any time of year. Trees remain healthier when pruning of healthy branches is done in winter months when trees are dormant, however it may be important to reduce the weight of tree branches before leaves fall or storms arrive. Consult a certified arborist when concerned about branch safety. • Certified Arborists

www.treesaregood.org•Consulting Arborists

www.asca-consultants.org

2. Reduce water use as weather cools. Check soil for excess moisture. Clay soils are very slippery when saturated. Tree roots can loosen and slip, and even large trees will blow over without adequate root support.

3. Young leaning trees with less than a 4 inch diameter trunk can be re-staked upright in wet winter soils. Larger leaning trees may respond to branch pruning that can balance and redistribute weight.

Luanne Leineke

•October and November are the best

months to plant trees. Roots get a

great start in cooler soil.

•Water when the soil feels dry and

crumbly. Decrease watering as the

weather cools.

•Remove weeds and add mulch.

Make sure the mulch is 4 feet in

diameter around your tree, 4 inches

away from the trunk, and 6 inches

deep.

•Check the stakes and ties. If your

tree can stand on its own, remove

them. If they are still needed, be sure

the stakes are firmly in the ground

and placed away from the trunk.

Make sure the ties are wrapped

loosely on the tree and tied firmly to

the stake to allow the tree to move.

•Avoid pruning in the fall. It is best

to prune in the winter

months.
