The Township of Teaneck is geographically split into 4 distinct quadrants (districts); NJ State Route 4 runs east/west and splits the township to a north-side & south-side, and the CSX River Subdivision Freight Line runs north–south and splits the township to an east-side and west-side. Due to the limited ways to cross either of the barriers, each district has a firehouse in order to facilitate a rapid response to a call.
