Tongue Freed From Cheek

It seems quite a waste to spend $1136/ft on the Mt. Vernon to Chamblee-Dunwoody stretch of Dunwoody Parkway. Not only is this pricey, it doesn't solve any real problems. In an upcoming diatribe we'll rant about the differences between destination transportation and recreation transportation, but for now let's look at the Village and see what we can do.

First let's observe some sanity rules and objectives:
  • Roads at or under a 25MPH limit will have not dedicated bike lanes--you'll share the road and if you cannot enforce a speed limit or share the road at these speeds there are deeper problems that no amount of pavement or striping will fix.
  • The entire run of Dunwoody Parkway should be at or under 25MPH.
  • Transportation IN the Village is not primarily for the benefit of those trying to get THROUGH the Village. We have through ways. Use them.
  • Passive speed control measures should be used as we're not likely to see active measures in force.
  • Some existing trees warrant saving but many do not and neither have a constitutional right to equal treatment or equal outcomes. Some will die, others will be planted.
  • We need to address more than just the needs of special interests, be they cut-through drivers in a hurry to get where ever or bike riders in a hurry to get back where they started. 
Based on the annotated map below let's look at what we could do to improve Life In The Village.


Tackling the 800 pound gorilla first the contentious part of the Parkway (shown above in green) would be reconfigured. Where possible trash trees (think Bradford Pear) in the median and those medians will be removed. Crepe myrtles are readily sacrificed as well. In the areas with no median the outer lane will become a small linear park with wide sidewalks and plantings including non-trash shade trees. You have one half the width of the median and the width of one traffic lane to work with on each side. In areas where there are high value, high quality trees in the median these will be preserved--there are a few. This will create traffic calming structures known as "center island narrowing" where lanes diverge around these retained medians. This is being used effectively on a similar road on at least one corporate campus in the area.

Now let's look at the oft neglected portion of Dunwoody Parkway stretching from Chamble Dunwoody down to the Publix center, past Car Repair Central and over to Restaurant Row ending at the four way behind Hickory House (shown in blue above). This certainly needs re-paving and curb improvements. Either the storm drain problem at the bottom of hill must be fixed or the area declared a federally protected wetland. This little stretch of road should not be costly to bring up to par with the rest of the Parkway, but it is important to the overall plan as will be shown shortly.

Then there are also some important additions (shown in red above). First, a round-about (the red circle) which is not only euro-chic but appropriately located near Dunwoody's British pub, and Alison's, whose proprietor sports a British accent, and D'Vine Wine bar, purveyors of wine from across Europe. Another critical component of the overall plan is an extension of the Parkway behind Moondog and dead-ending on Nandina after a dog-leg to the east. This route is already paved, but not as part of the Parkway and rights of way would need to be acquired and the roadway brought up to Dunwoody Parkway standards. Another added element is raised pedestrian crosswalks at key locations around the Parkway (shown as red squares) which not only provide clearly marked crossings for pedestrians but offer a similar alert for drivers. As a traffic calming measure they complement the center islands. There are other additions and changes, but these are largely minor, like fixing the Fresh Market entrance at the Chevron station which is awkwardly angled. A Citizens' Committee can handle these details.

And what do we get for all this trouble? Glad you asked.

  • These improvements allow us to ban all left turns from shopping center parking lots on Chamblee Dunwoody. This is long overdue and eliminates one source of accidents that waste our police budget.
  • Nandina can be made one-way south. Folks leaving Moondog will be able to turn right on Nandina, right on the Parkway to the round-about and have their choice of traffic lights to head their merry way. Something may catch their eye and they just might pick up a little something extra. 
  • Shoppers can move with relative ease through all areas of the Village without the current interference of commuter traffic.
  • The City will get the consistent "look and feel" some seem to want.
Most importantly we get past the current dog fight created by focusing only on what some silly grant covers.
