In what scenario might cross streets be required in addition to a hundred-block description?

• A. In dense urban areas where multiple blocks are near the same major street or when the block is ambiguous.
• B. Only during night hours.
• C. When there is no cross streets.
• D. When there is a water feature.

Answer: (A)

Cross streets are added when the hundred-block description could refer to more than one location along the same major street. In dense urban areas, several blocks sit close together or near the same major street, so the hundred-block alone can be ambiguous. Including the intersecting streets pinpoints the exact block and helps responders reach the right spot quickly. The other options don’t create this kind of location ambiguity—night hours don’t change how blocks are identified, and having no cross streets or a water feature doesn’t inherently require or justify adding cross streets.
