Environmental Resilience at Home: The Story of a Rain Garden

Posted: by

By Artie Harris, Chair, Montgomery County Planning Board

This is the story of my rain garden adventure in the front yard of my family’s Takoma Park home.

Every time there was a big rain, water rushed down our driveway into the street, joining with runoff from other houses in a fast-flowing gush along the curb. Since our house is on a hill, stormwater has never caused us any problems, but we knew our downstream neighbors suffered from flooded basements. We also knew the result of all this cumulative discharge was harmful to the beloved Chesapeake Bay.

Many Montgomery County homes have a similar problem, but in our case, it was especially obvious because we had a gravel driveway. … Continue reading

Bethesda Green, TEDx, and Your Dinner

Posted: by

Bethesda Green sponsored a TEDx meet up this past Saturday on “Changing the Way We Eat,” and although the speakers were based in New York, the local viewers took time to introduce themselves and their efforts in local food and to discuss the potential for local food in Montgomery County.

 

So after Laurie David talked about the importance of family dinner and Carolyn Steele’s TED talk about How Food Shapes our Cities, we heard from Mike Kennedy, a board member of the innovative model Fox Haven Farm, from Kristina Bostick who works with Montgomery Countryside Alliance to make the County’s Agricultural Reserve into a food porducing resource, and Greg Glenn of Rocklands Farm, which is starting out with … Continue reading

How can planning influence climate change numbers?

Posted: by

As we start writing the code for the new zoning ordinance, a “big picture” view seems in order. The biggest-picture formula in climate change, called the Kaya identity, is:

F=Pgef

F = Global CO2 emissions (combustion, flaring of natural gas, cement production, oxidation of nonfuel hydrocarbons, and transport) P = Global population (total number of human beings) g = Consumption per person (gross world product divided by population) e = Energy intensity of gross world product (global energy consumption divided by gross world product) f = Carbon used to make energy (global carbon dioxide emissions divided by global energy consumption)

The most obvious thing about this equation – if you remember even grade-school math – is … Continue reading

energy and beauty in symmetry and repetition

Posted: by

I think there is a particular kind of aesthetic beauty in the simple repetition of forms over large expanses of contrasting landscape. Even more so when those repeated forms provide sustainable energy.  The just-approved off-shore wind farm is one such example, solar “farms” are another.

The well-heeled opposition to the mentioned wind farm has only posed the aesthetic argument that this visual intrusion into the seascape must by definition be negative.  I disagree.  I think it’s quite attractive, calming, and interesting.  I think the connotations only increase our appreciation of the natural environment that serves as the backdrop (or, more appropriately, the visual context/physical participant).  My interpretation is built on the … Continue reading

Catherine Mohr: Building Green

Posted: by

Ever feel like you’re being watched by the Green Police? Have a loved-one who thinks that tossing a newspaper in the trash is the equivalent of clubbing a baby seal? Tired of transparent marketing campaigns for products with dubious environmental benefits? You’re certainly not alone.

In this video from TED Talks, Catherine Mohr rightly calls out the insanity of nitpicking over every paper towel or coat of paint, and identifies the real elephant in the room: embodied energy. Embodied energy is the total amount of energy necessary for an entire product lifecycle, including everything from transportation to installation to decomposition. When used as a metric to evaluate sustainable construction construction practices, it can reveal the real opportunities for … Continue reading

Darker Skies = Brighter Future

Posted: by

In honor of the upcoming Earth Hour on March 27, we offer a random assortment of efforts to reduce light pollution, conserve energy, and protect migratory birds by minimizing wasted photons. Learn more at the International Dark-Sky Association.

Earth Hour’s website, sponsored by WWF, has a clock counting down the seconds until March 27 at 8:30pm when everyone partaking will shut off their lights, especially exterior lights. Check out these awesome examples from last year.

A good summary of recent (and not so recent) legislative efforts in Maryland has been provided by Dr. Harold Arlen Williams, director of the Montgomery College Planetarium. In DC, City Wildlife has spearheaded a campaign to help migratory birds.

On a side note, public … Continue reading

Peter Calthorpe on Transit-Oriented Development

Posted: by

Via Fast Company

Portland has long been one of the most celebrated cities in terms of planning and sustainability. Peter Calthorpe is one of the original pioneers of transit-oriented development. In this video, Calthorpe does a nice job of succinctly laying out the principles of transit-oriented development, namely walkability and diversity of population and land use.

Broadway Pedestrian Boulevard Made Permanent

Posted: by

After months of study and deliberation, New York City has decided to make its pedestrian-priority spaces a permanent fixture on sections of Broadway around Times and Herald Squares. The decision to keep the revised street plan, which had been operating under trial review since last summer, came despite vehicle travel times falling short of projected improvements. The plan was originally sold on the basis that it would improve vehicle flow by 17%. It improved 7%.

More importantly, the roadway enhancements vastly improved pedestrian and motorist safety. According the City’s Department of Transportation, pedestrian injuries are down 35% while motorist and passenger injuries decreased 63%. And 80% fewer pedestrians are walking in the streets despite increased usage of Times and Herald Squares, ostensibly due to … Continue reading

Project Profile: The Burnside Rocket

Posted: by

Tacking onto Elza’s post on Silver Spring’s future form, I came across this building a few weeks ago and couldn’t help but think of Fenton Village. It’s cheerful, gritty, and almost certainly would feel at home in a neighborhood that already boasts an array of colors, from the similarly red Pyramid Atlantic to the tastefully pink Jackie’s Restaurant.

And while the Burnside Rocket may seem to offer little in the way of architectural distinction other than a few eccentric shutters painted by local artists (which I think are quite neat), between its crimson painted walls is a powerhouse at work. The LEED-Platinum certified structure is built both to last, approximately 300 years according to the project’s website, and operate … Continue reading
