The Greater North Park Community Plan on the books today doesn’t contemplate the existence of microbreweries or its artisan brethren, like bakeries, coffee roasters and candy makers. So unless a proposed zoning change is included in the update, the plan could effectively ban future microbreweries in the neighborhood.

Even as the urban neighborhood has become a sort-of template for city planners, it’s still facing some of the usual tensions as it tries to map out its development future. The dispute is a reminder for the city that cutting greenhouse emissions in half is harder than simply announcing it wants to.

Under a new plan, the area near the trolley station at 32nd Street and Commercial – currently home to heavy industrial activities like metal scrapping, recycling and auto-wrecking – would have its zoning changed so new developments could include dense housing and retail or office spaces.
