Lost in all the drama surrounding the bitter fight over the liquor license of Union Hall in Park Slope was another important local measure that was up for a decision by Community Board Six on Wednesday night: the “narrow streets” zoning text amendment in Carroll Gardens. That text change would redefine a number of very narrow streets in the neighborhood as actually being narrow for zoning purposes, reducing the density of what could be built. (The streets are currently defined as “wide” for the zoning code, allowing bigger buildings and additions.) The discussion of the amendment actually took nearly an hour and a half as there were objections from opponents, some of whom bitterly object to the change. In the end, the board voted 20-7 in favor of the measure (with 7 abstentions). The change must go through the full city land use review process and, ultimately, be approved by the City Council.
