What is the primary objective of the Major Street Hundred Blocks practice?

• A. Memorize every street name.
• B. Accurate and rapid location description using standardized block-and-street framework.
• C. Only use cross streets.
• D. Rely on landmarks only.

Answer: (B)

The main goal is to describe where something is quickly and precisely using a consistent block-and-street framework. This means naming the street and the corresponding block, so you can say something like the 600 block of Oak Street or between the 500 and 600 blocks on Pine Street. This approach gives a clear, universal reference that responders can actions on fast, without needing to memorize every street name or rely on vague cues.

Memorizing every street name isn’t practical in a large city, and using only cross streets can lead to ambiguity if one street isn’t well known or easy to confirm on the ground. Relying solely on landmarks is unreliable because landmarks can change or be absent in the moment. The standardized block-and-street method provides precise, scalable location descriptions that help coordinate and route units efficiently.
