Paul lives on O Street. People who live on O Street are very interested in the project. It will bring a severe upgrade to the neighborhood to their east, as well a supermarket that might be actually be useful. It may also bring a lot more traffic. Traffic flow on O and P is a major concern.
That's a little euphemistic. The concern is getting overrun with traffic on the 900 block of O and P Streets. O Street is wide enough for local residential traffic, but just isn't wide enough to support much extra traffic to and from the new development. P Street only supports one lane of parking, not two. "Traffic plan" is an on-going conversation topic in the neighborhood.
One hopes the traffic issues are resolved before it gets serious. There's probably a year to get a consensus locally. Changing blocks from two-way to one-way leads to more local disagreement than one would think, but will probably be part of the solution. Maybe some of those speed humps as on the 400 block of M Street, or other "traffic calming" ideas. Once the authorities see that the neighborhood has consensus on changes, they'll pay attention and reasonable ideas can probably be implemented in several months. Unreasonable changes probably involve any loss of parking.
Any ideas where to put the trafficc circles?
