An Arlington environmental group is claiming that Arlington’s recent tree canopy assessment is misleading.

The tree canopy study found that, from 2011-2016, the tree canopy increased one percent to 41 percent. The Arlington Tree Action Group claims that the two percent margin of error on the county’s study cancels out its findings.

A press release from the tree group also notes that the county failed “to emphasize a decrease from the 43 percent recorded in 2008.”

The press release from the Arlington Tree Action Group is below.

ATAG Challenges County’s Misleading Claims on Tree Canopy Study

Arlington, Virginia – April 12, 2018 – Arlington County is using an arsenal of its public outreach resources to present an overly optimistic picture of the health of the forest resources based on a 2017 tree canopy study according to the Arlington Tree Action Group (ATAG).  The study concluded that the tree canopy increased by 1% between 2011 and 2016 but the County media push fails to emphasize a decrease from the 43% recorded in 2008. More alarming for 10 civic association neighborhoods is the scant recognition of the actual loss of more than 5% of their trees over just five years, with another 14 neighborhoods losing up to 5%. The County has instead declared that the trees are “on the rebound” based on the report.

After reviewing the report, Jarlath O’Neil-Dunne, Director, Spatial Analysis Laboratory, Rubenstein School of Environment and Natural Resources, the University of Vermont, concluded that the accuracy of the data used was only 94% making the findings publicized by the County highly questionable. In keeping with the County initiative for more open data, ATAG is concerned that the information disseminated must be accurate.

The 2004 Arlington County Urban Forest Master Plan called for an increase in the tree canopy from the estimated 41% at that time. The Plan also called for extensive programs for the preservation and planting of trees. Arlington County does not have an inventory of the trees on public lands that many jurisdictions such as the District have established. The County currently has capital projects including stream restorations, community centers, and park developments, that will remove hundreds more trees in the next few years, dwarfing the public and private tree planting programs underway.

ATAG is concerned that the County outreach mischaracterizes the study results which could delay addressing serious environmental, health and economic challenges accompanying urban tree canopy loss. The outreach has included presentations to the County Board, the Urban Forestry Commission and other County commissions and civic associations, as well as articles in “The Citizen” newsletter to all residents, pages on the County website, and posters in parks.

ATAG is a group of concerned Arlington citizens working to preserve the sustainable urban forest, promote green infrastructure, and protect the environmental ambience that makes the community economically attractive. Working with individuals and established community organizations, the group seeks to highlight important issues facing Arlington’s urban forest and bring together resources to maximize their goals.

Eagle-eyed readers of this site may have noticed something odd in this past Friday’s weekend discussion post: namely, the inclusion of an article from December among the most-viewed stories of the week.

We also found that unusual, so we did a bit of digging. It turns out, there have been more than 6,000 views of the article, “County Wins Top Environmental Award from U.S. Green Building Council,” over the past week.

Here’s an excerpt:

Arlington County is the first community in the country to win a top award for its environmentally-friendly policies from the U.S. Green Building Council.

The county was named a Platinum level community by USGBC under its new LEED for Communities program.

USGBC said the certification recognizes the county’s creation of a “sustainable and resilient urban environment that has long-proven success in reducing greenhouse gas emissions, managing stormwater, ensuring economic prosperity and focusing on education, affordable housing, health and safety for residents and businesses.”

So from where is all this newfound interest in Arlington County’s sustainability bonafides coming? From Amazon.com, it seems.

The vast majority of the traffic to the page over the past week that can be tracked came from what appears to be an internal Amazon.com page devoted to its HQ2 search. Arlington, of course, is in the running as one of the potential landing spots for the company’s second headquarters.

Below is a chart showing traffic to the page, via Google Analytics.

No other page on ARLnow.com has a similar level of traffic coming from Amazon.

Last week a noted NYU professor who has written about the company opined that New York City and the D.C. area are among the most likely finalists for HQ2, due to a combination of being destinations for talented workers and being places that Amazon CEO Jeff Bezos likes to frequent.


Arlington’s recycling rate rose to 48.5% in 2017, up slightly from 2016. The county credits the rise to its implementation of year-round, weekly curbside yard waste collection for homes and duplexes.

The recycling rate was 46.8% in 2016 and 44.5% in 2015, the year that year-round collection was unanimously approved by the County Board. The project was expected to divert up to 9,000 tons of compostable materials from regular trash collection. It came with a $47 per-year price tag for Arlington homeowners.

Arlington’s 2016 recycling rate was well above the Environmental Protection Agency’s 2014 national estimate of 34.6%.

The amount of yard waste that was thrown in the trash plummeted from 26% to 5%, according to the 2017 Arlington County Annual Report.

An Arlington County Board recommendation cited a September 2015 survey which found that 70% of single-family home Arlington residents believed that increasing the county’s recycling rate was important. There were 4,283 survey participants. The survey also asked whether or not those residents supported year-round yard waste collection despite the additional cost, to which 60% indicated that they did support the initiative.

In 2017, Virginia’s Dept. of Environmental Quality awarded Arlington a bronze medal for the year-round yard waste collection as part of the governor’s environmental excellence awards.

Why did the salamander cross the road? To get to the vernal pool breeding grounds, of course.

Most people wouldn’t laugh at that, but the joke might have killed at Thursday’s salamander patrol training session at Arlington’s Long Branch Nature Center.

The nature center holds yearly salamander training sessions to educate volunteers on the dangers that salamanders and other vernal-pool-dwelling amphibians face during the annual migration.

Amphibians generally live in ponds but some, like the spotted salamander or wood frog, only live in vernal pools — watering holes that dry up in the fall. These are ideal spots for the critters to thrive in, because predators like fish and other amphibians prefer year-round pools.

But because only two or three vernal pools remain in the increasingly urbanized county, hundreds of salamanders and wood frogs have no choice but to cross the pool-adjacent driveways and sidewalks, according to Jennifer Soles, an Arlington County naturalist and long-time Arlington resident.

Soles began the salamander squad program in 2013 after attending a master naturalist training the year prior. As Long Branch Nature Center volunteers were leaving the class, salamanders and frogs began their breeding ground migration — across the parking lot, and under a lot of car tires.

“They’re all there because they love nature and it’s their master naturalist training,” said Soles. “And everyone is running over the frogs and salamanders.”

Soles grabbed a flashlight and began escorting the unhurried salamanders off of the pavement, joined by other horrified naturalists.

Arlington’s naturalists have since tried to prevent further amphibian annihilation through the salamander training sessions. At the Feb. 8 training session, at least 16 community members learned how to protect their local croakers from another Arlington County naturalist, Rachael Tolman.

The session focused on frog and salamander biology and breeding habits, and taught volunteers safe handling practices. Tolman walked volunteers through filling out scientific forms that allow on-site naturalists to predict travel patterns.

“If it’s a little squish, it’s a [spring] peeper, if it’s a medium squish, it’s a wood frog,” said Tolman, explaining how to fill out the alive-or-dead count portion of the form for the rundown animals. “If it’s kind of a spotted, long squish, it’s probably a spotted salamander.”

A salamander patrolman is nothing without his or her tool kit, which includes a reflective vest, headlamps, pens — and a garden spade for scraping squished salamanders off of the road.

While the event was intended to be for ages 13 or older, few teenagers were in attendance. Most volunteers were much older with a more developed environmental interest.

Peter Hansen, a Federal Reserve Board researcher, is a 24-year-old Arlington resident and one of the county’s master naturalists.

“I saw the email blast about the salamander patrol, and it sounded really hype,” said Hansen, noting that several of his friends are nature enthusiasts that he admires for their vast knowledge of the environment.

“I can add a lot of color to my experience in nature,” said Hansen. Most likely, he’ll be returning to serve on the salamander squad.


Arlington County is the first community in the country to win a top award for its environmentally-friendly policies from the U.S. Green Building Council.

The county was named a Platinum level community by USGBC under its new LEED for Communities program.

USGBC said the certification recognizes the county’s creation of a “sustainable and resilient urban environment that has long-proven success in reducing greenhouse gas emissions, managing stormwater, ensuring economic prosperity and focusing on education, affordable housing, health and safety for residents and businesses.”

LEED — Leadership in Energy and Environmental Design — is a rating system by USGBC that evaluates how environmentally-friendly buildings are.

“It is truly an honor, and a validation of Arlington’s commitment to sustainability, to be the first to earn LEED for Communities Platinum certification,” County Board chair Jay Fisette said in a statement. “This has been a community effort, achieved by having a vision of combating climate change and promoting energy efficiency on a local level, and putting in place innovative policies and practices to achieve it. Now, more than ever, the responsibility for progress on climate change rests with local and state governments and with the private sector.”

The award honors communities that have set goals for environmental sustainability and then met them. It tracks energy, water, waste, transportation and human experience (education, prosperity, equitability and health and safety) before awarding certification.

“Arlington County understands the value of LEED and its ability to help set goals and deploy strategies that can improve the quality of life for residents across the community,” Mahesh Ramanujam, president and CEO of USGBC, said in a statement. “Arlington’s LEED for Communities Platinum certification demonstrates a commitment to improving performance and creating a more resilient and sustainable future.”

(Updated at 3:20 p.m.) Arlington County just announced that it has joined other counties, cities, businesses and colleges in signing an open letter pledging to meet the goals of the Paris Climate Agreement.

President Trump announced last week he will withdraw the United States from the pact to help preserve American jobs and avoid placing heavy burdens on the country’s taxpayers. The decision brought swift condemnation from local elected officials.

County leaders joined on Monday (June 5) an open letter to the international community and parties to the Paris Agreement entitled, “We Are Still In.” The letter promises that efforts to reduce greenhouse gas emissions will continue, regardless of federal policy.

“Arlington stands with communities across our nation and around the globe who recognize that climate change is real and that we must, both on the local and on the global level, meet its adverse effects with strong, effective action,” said County Board chair Jay Fisette in a statement. “Just as we joined the Compact of Mayors in 2015 and agreed to set goals for reductions in greenhouse gases, so do we join the effort today of local communities that are pledging to uphold the Paris Agreement, even if the federal government does not.”

The District of Columbia has also signed on to the pact and Virginia joined a similar state effort this week.

In light of President Trump’s decision, the County Board will consider a resolution at its June 17 meeting reaffirming Arlington’s commitment to combating climate change.

In a press release, the county touted its efforts already in the fight against climate change:

Arlington County adopted a forward-thinking Community Energy Plan (CEP) in June 2013, as an element of our Comprehensive Plan. The award-winning plan is a long-term vision for transforming how Arlington generates, uses and distributes energy. Its goal-setting and methods of achievement are consistent with the Mayors National Climate Action Agenda and the Paris Accord. Arlington’s CEP aims to reduce greenhouse gas emissions by 75 percent by 2050, and greenhouse gas emissions already have fallen 18 percent in Arlington between 2007 and 2015.

In 2015, Arlington signed the Global Covenant of Mayors for Energy and Climate, sponsored by the Compact of Mayors – open to any city or town in the world willing to meet a series of requirements culminating in the creation of a full climate action and adaptation plan.

In 2012, Arlington exceeded our goal of reducing government-wide energy usage by 10 percent, using the year 2000 as a baseline. Currently, we’re competing in the U.S. Department of Energy’s Better Buildings Challenge to reduce municipal building energy usage by 20 percent by 2020.

Our Arlington Initiative to Rethink Energy (AIRE) helps our community make smart decisions about energy and supports individual actions that improve and sustain Arlington’s quality of life. County government buys more than 30 percent of its electricity as certified green power and buys carbon offsets against 100 percent of its natural gas use. Arlington is home to Discovery Elementary, the largest “net zero energy” elementary school east of the Mississippi River.

At its meeting in June, the County Board will consider a resolution reaffirming Arlington’s commitment to combating climate change and to the goals of our Community Energy Plan.

Arlington will continue to work to make our County more prosperous, healthful, safe and secure through its efforts to rethink energy and protect the environment.

The Arlington County Board will consider a plan to make a stretch of Williamsburg Blvd a so-called “Green Street” at its meeting Saturday.

The section of Williamsburg Blvd, between 33rd Road N. and 35th Street N., would have new trees added as well as two 1,000-square-foot rain gardens in the median. The project is intended to improve local water quality and address permit requirements as part of the county’s Green Streets project for stormwater management.

County staff estimated that installing the trees and rain gardens will treat runoff from 2.2 acres of impervious surfaces that do not allow rainwater to soak in. That water then runs off into the Little Pimmit Run watershed, which leads to the Chesapeake Bay, with Arlington under instructions along with other jurisdictions to reduce pollution in the bay.

If the County Board approves the plan, a contract worth an initial $1.23 million would be awarded, with $246,000 in contingency.

County staff recommends approval of the project, which is being coordinated with the second phase of improvements to Old Dominion Drive. Construction is set to start in June or July.


Arlington Public Schools says it has saved more than $2 million by moving from paper flyers to electronic messaging.

APS implemented a system called Peachjar last year, replacing paper-based “backpack mail” with email that’s sent directly to the inboxes of elementary and middle school parents.

With a click, families can also use Peachjar to register their children for school events, after-school programs and other activities.

In a statement issued just prior to Earth Day, APS said the switch has saved $2.1 million in paper costs and staff time, while saving 475 trees from being cut down.

APS said the switch has been part of an “effort to reduce waste, promote sustainability, and save valuable time and money.”


Rep. Don Beyer in his Capitol Hill office (file photo)Rep. Don Beyer (D-Va.) is unhappy with the environmental implications of president-elect Donald Trump’s cabinet picks.

In a statement last night, Beyer blasted Trump’s picks for EPA administrator, Secretary of State and Secretary of Energy.

The full statement is below.

The trio of Scott Pruitt for Administrator of the Environmental Protection Agency (EPA), Rex Tillerson for Secretary of State, and Gov. Rick Perry for Secretary of Energy confirms our worst fears about President-elect Trump’s intentions on climate change and the environment.

As Oklahoma’s Attorney General, Scott Pruitt organized and led a national push to oppose the EPA. He made himself the mouthpiece for the fossil fuel industry as it fought protections of air and water quality. As a denier of climate science, he is unqualified to run the nation’s premiere agency on the environment and the fight against climate change.

At the helm of Exxon-Mobil, Rex Tillerson continued the corporation’s efforts to undermine climate science as well as its unyielding insistence that fossil fuels remain the dominant, if not sole, energy source for the immediate future.  Exxon-Mobil’s regard for shareholders alone, and its refusal to acknowledge that stock value could be married with a wiser and more sustainable long-term world energy portfolio caused untold harm. It is appalling that the Secretary of State who negotiated the Paris Agreement, perhaps the most ambitious step towards fighting climate change in history, could be followed by this nominee.

Rick Perry impressed almost no one during his presidential run, and his most famous statement was his call to abolish the very agency he has been tapped to lead, once he remembered that it is called the ‘Department of Energy.’ The notion that he will succeed the Obama-era Steven Chu, a Nobel Prize winner, and incumbent Ernest Moniz, an MIT nuclear physicist, is at once saddening and frightening, as was his call to close the agency tasked with developing clean energy technologies.

Climate change remains the world’s greatest threat. Delaying or reversing our efforts to fight climate change will have potentially catastrophic effects on the planet.


View of Key Bridge, the Potomac River and D.C. from the Waterview building in Rosslyn

There’s a renewed push for action on the decades-old plan to build a boathouse in the Rosslyn area.

County and federal officials want the public to know that although the project has stopped and restarted several times, it definitely hasn’t been scrapped.

The idea of a boathouse has been supported by the county, by residents (particularly families of high school crew team members) and by developers.

Arlington County has been working on various forms of the boathouse project since the 1990s. It has collaborated with the National Park Service because the county’s shoreline along the Potomac River technically is NPS property.

Map of land acquired for proposed boathouseIn October, the county requested that the Commonwealth of Virginia quitclaim any interest it has in the street that fronts the property at 1101 Lee Highway. The county had purchased the Lee Highway land parcel in 2014 for $2.4 million with the listed intent of using the land for possible boathouse-related purposes.

The county requested the quitclaim because it’s unclear exactly who owns and maintains this small portion of the land along the former Lee Highway right of way. VDOT now has to approve the quitclaim — which has no fiscal impact to either party — and the county believes that should happen by or shortly after the new year.

The county points out that this section of land also is the only service vehicle access point if a boathouse is built. Public parking and drop-offs would be located in a safer area further away from the busy intersection with N. Lynn Street and the I-66 off-ramp.

Any progress on the boathouse plan is theoretical until NPS completes an environmental study — as required by law — showing how such a project would impact the area’s natural and cultural resources.

NPS launched an environmental impact statement (EIS) in 2012, with funding secured by former Rep. Jim Moran (D-Va.). The study involved getting community feedback on locations for a potential boathouse.

But the EIS was put on hold and NPS is investigating whether it can instead do an environmental assessment, which is a similar but less intensive study that takes less time to produce. The EA would incorporate the information already gathered during the now-stalled EIS.

NPS launched a transportation study last year to determine what impact a boathouse would have on the area’s existing transportation network. The agency has been collaborating with Arlington County and VDOT for that study and in compiling a final report on the transportation impacts.

Proposed locations for Arlington boathouse Although 1101 Lee Highway was intended to be a location for a boathouse facility, that’s actually not set in stone. That parcel of land is called an “upper site” and cannot effectively host a boathouse on its own without a nearby “lower site” near Theodore Roosevelt Island where boats could be stored and launched. If NPS deems another site better suited for a boathouse, Arlington County could use the Lee Highway land for something else.

“In addition, or as an alternative use, the county may put other passive or recreational uses on the parcel,” said Arlington Dept. of Environmental Services spokeswoman Jessica Baxter. “We need to wait until a final determination is made by the National Park Service on the parcel, so other uses aren’t actively being pursued.”

A study for another hot project — the Rosslyn-Georgetown gondola — in relatively the same area was released last month, but Baxter says it’s far too early to consider that an option for the land parcel. In fact, she said it’s premature to even comment on the feasibility of a possible gondola project because the study hasn’t even been reviewed or vetted by county staff.

As far as the next steps for moving forward with the boathouse, NPS hopes to announce a decision about the environmental study and its possible transition to an environmental assessment by early 2017.

If the agency announces it is able to go forward with an EA instead of an EIS, it could potentially reveal a preferred boathouse site at that time as well, although the location decision is not required until the final environmental study results are released.


Barcroft Park/Four Mile Run clean-upA local organization is looking for Arlington residents to help remove litter from Four Mile Run next month.

Volunteers with Arlingtonians for a Clean Environment (ACE) will help pick up trash from the stream during the organization’s annual cleanup at Barcroft Park on Saturday, Sept. 17.

Those who sign up for the event will be tasked with removing debris from Barcroft Park and along the banks of Four Mile Run.

The cleanup is being held in conjunction with Clean Virginia Waterways Day and the Ocean Conservancy’s International Coastal Cleanup. As part of its collaborative efforts, ACE will collect data on the garbage its volunteers remove from the stream.

“We will submit the data to both groups to contribute to an understanding of how litter is impacting our waterways and the wildlife that depends on our waterways,” said Elenor Hodges, executive director at ACE.

Those interested in helping out should bring along sturdy shoes they don’t mind getting wet, work gloves and a water bottle and wear long pants and sleeves to protect against poison ivy, Hodges said.
