Carroll Gardens & Columbia Street
LL 162 Rezoning Lookback Report
Introduction
The Carroll Gardens and Columbia Street rezoning ( C 090462 ZMK ) responded to calls from Brooklyn Community Board 6 and other local groups to “respond to recent out-of-scale development.” This rezoning followed a previous rezoning of Carroll Gardens in 2008 that also aimed to “preserve the existing built character” of the neighborhood. Zoning changes included:
- R6 to R6A, instituting height limits on medium-density residential development.
- R6 to R6B, reducing the allowed density and instituting height limits on medium-density residential development.
- R6 to R7A, increasing the allowed density and instituting height limits on medium-density residential development.
- Changes to commercial overlays, allowing neighborhood commercial uses.
This map shows the zoning changes that were part of the rezoning as one of three categories. Click the button in the bottom left-hand corner of the map to access a legend.
Upzoned areas are defined as an increase in the allowed dwelling units per acre.
Downzoned areas are defined as a decrease in the allowed dwelling units per acre.
Unchanged areas have no change to the allowed dwelling units per acre.

Population and demographics
Census tracts used to define the study area and context area for Census and ACS variables.
How to read demographic charts
The I-shaped figures are called error bars. Error bars account for uncertainty in the sample data by representing the range in which the data could fall.
Data drawn from a larger sample are more accurate and have a smaller error bar, which is why the size of the error bar gets smaller as the geography increases in size.
An upwards arrow (↑) signifies a statistically significant increase.
A downwards arrow (↓) signifies a statistically significant decrease.
A dash (-) signifies no significant change. This may occur because the values remained about the same or because the margins or error are such that it is not possible to know whether the values changed.
Each variable also includes a chart for New York City to compare changes in the rezoning or buffer area to citywide trends.
