As mentioned at the general meeting, the upgrade of the Gowanus wastewater evacuation facility will have some impact on our fair neighborhood, and in particular the Columbia/DeGraw Street intersection. The estimated total building time is four years. Traffic on Columbia and DeGraw will be affected by lane closures and periodic street closures over a period of two years and four months, starting in February 2010. The DeGraw part of the intersection will be closed for approximately 12 months, and there will be an additional lane closure on DeGraw for 14 months. However, several noise, soil and ground water test sites are planned, which very well may be of use for the neighborhood.
The plan in its entirety may be found here:
The effects on our neighborhood are mainly found in the appendixes.
