Whenever one considers moving to a new area, it's important to get a good grasp of how things work in the new community. This includes learning a bit about their government and how things get done. Moving to Park Slope should be no different.
Since Park Slope is a community in Brooklyn, NY, the Mayor of NYC is the head of the government. Whether it is help with trash removal, police, fire, or other city services, the City of New York is ultimately in charge. The area has representatives that can help to liaise, but the Mayor has a firm grasp of what is happening in all of the boroughs as well as the various communities. The Brooklyn City Council Members are the people through which many of the issues in Brooklyn government, and thus Park Slope, pass. Currently, all of the members of the Brooklyn City Council are democrats.
The Park Slope Civic Council plays an integral role in the area. The Council is responsible for keeping the historic district of Park Slope safe, as well as keeping the streets safe and clean. The Council works very hard to make sure that the neighborhood retains its unique flavor. They even hold an annual Halloween parade for children in the area. It's one of the most popular events in the city, and it draws more than 10,000 participants each year.
The Council holds many other events throughout the year as well. While they may not have a large hand in Brooklyn government per se, they are very instrumental in making sure that everything in the community remains as beautiful and pleasant as it is today. When you move to Park Slope, you might want to see what other events they hold and see if you can lend a hand.
