Fixing suburbs with green streets that accommodate everyone

We’ve made such a mess of the suburbs we constructed in the last fifty or so years that one wonders whether they can ever be made into something more sustainable.  Strip malls, traffic jams, cookie-cutter subdivisions, diminished nature, almost no sense of outdoor community.  We all know the drill: there are nice places to be in America’s recently built suburbs, but we have to know where they are and drive to them through a visual and environmental mess to get there.

One of the most challenging aspects of suburbs, and of the prescriptions for improving them, is the character of their roadways.  Most of us take the poor design of our streets – the most visible part of most suburban communities, if you think about it – so much for granted that it never occurs to us that they actually could be made better for the community and for the environment.  Consider, for example, main “arterial” streets so wide that pedestrians can’t cross them, even if there is a reason to; little if any greenery to absorb water, heat, or provide a calming influence; or residential streets with no sidewalks.

This is where Montgomery County, Maryland’s new streetscape initiative comes in....

Here’s how the county’s web site describes the initiative:

“Streetscapes and public rights-of-way are valuable real estate, although people often forget they are not just about moving motor vehicles. They are also the front doors to homes, schools and businesses. As Montgomery County urbanizes and its spaces become more constrained, planners are re-considering how to create more value from our streetscapes.

“The Planning Department conducted a year-long project on environmental site design (ESD) focused on street edges. ESD integrates site design, natural hydrology, and other controls to capture and treat runoff.

“In addition to collecting drainage and wastewater, roadsides accommodate utilities, as well as provide space for pedestrians and off-road bicyclists, but trees and natural vegetation have often taken a back seat to other uses.

“This project has resulted in plans for retrofitting road sections in suburban and urban areas to better handle stormwater and improve the environment for pedestrians and cyclists in addition to motorists. Planners are working with County agencies and the County Council to establish policies to encourage ESD practices along county roads.”
