The price of getting there

Commuters heading to Washington DC were surprised to see tolls as high as $40 earlier this week. A congested 10-mile segment of I-66 in Northern Virginia opened to solo drivers as long as they were willing to pay a premium price. (Vehicles with two or more people are exempt from the toll.)

The state’s highway department is legally required to set the toll at a level that will allow traffic to flow freely (55 mph). This means the tolls have to be set high to prevent the lanes from becoming overcrowded and congested. In an unusual way this high toll illustrates the high cost of roads that are under used.

I recently learned of a different approach to managing congestion called Pico y Placa (peak and plate). This rule restricted a portion of the city’s cars from driving during peak commuting hours based on the last digit of the license plate. This rule forced drivers to find an alternative method of getting around during peak hours of congestion. Enrique Peñalosa pioneered this approach in Bogota, Colombia.

While drivers in Northern Virginia are understandably upset about the high cost of the toll road, I doubt they would be any happier with the Pico y Placa rule. Americans tend not to like restrictions on their freedom.

There are no quick fixes to auto congestion. Eventually, drivers pay for the privilege of traveling in crowded places. The city of London has charged drivers who enter the center city for nearly 15 years. Yet I’m not aware of any North American cities that have followed their lead.

The only long term solutions involve building communities that allow us to remove the auto from the equation by enabling citizens to make trips on foot, bicycle or transit.

A Shedload of Sheds

The ‘shed is an ecological framework that has expanded into a variety of topics. This post attempts to define all of the known ‘sheds and explore how they impact regional issues such as climate change, economics, and health.

  • Watershed – this is by far the most well known sort of ‘shed to planners. In North America it is synonymous with a drainage basin or catchment area.  In a sense, this is the “original ‘shed” as many people are exposed to this ecological concept before they learn any others.
    • The watershed often defines where drinking water, wastewater, and drainage (stormwater management /  flood risk) are managed. While these boundaries rarely align neatly with political jurisdictions, other governance structures have been established in key areas to address impacts to these ecological systems.
    • Drainage basins don’t typically align neatly with groundwater systems. This can cause confusion in places that rely on groundwater for drinking and irrigation.
    • Active environmental management of watersheds didn’t start in the US in earnest until the 1970’s with the Clean Water Act.
