What is the primary benefit of using the hundred-block system?

• A. It increases complexity of routing.
• B. It reduces miscommunication and speeds response by standardizing location references.
• C. It eliminates the need for cross streets.
• D. It relies on landmark descriptions only.

Answer: (B)

The hundred-block system gives a simple, predictable way to locate places by using block numbers along a street grid. When you hear a location described by its block, responders immediately understand the general area and approximate distance from a known starting point, without needing a local map or prior familiarity with the neighborhood. This consistency reduces miscommunication because everyone uses the same frame of reference, which speeds up dispatch and response. It isn’t about adding routing steps; it makes routing more straightforward by translating a block description directly into a map view and a route. It doesn’t eliminate cross streets or rely only on landmarks—cross streets still refine location, and landmarks alone can be unreliable—whereas block numbers provide a stable, precise reference that stays constant over time.
