If a location is described as the 1st block of a major street with no quadrant, what does this indicate?

• A. It indicates proximity to the baseline on that street; quadrant information should be sought to pinpoint precisely.
• B. The location is already precise and no quadrant is needed.
• C. Landmarks alone can determine the position.
• D. The street name is unknown and cannot be used.

Answer: (A)

In this grid system, blocks are measured from a central Baseline and Meridian, which split the city into quadrants (NE, NW, SE, SW). Saying a location is the first block on a major street means you’re very close to that Baseline along that street. But without quadrant information, you can’t tell which quadrant or exact side of the Baseline the block sits in, so you need the quadrant to pinpoint the precise block. That’s why this descriptor indicates proximity to the Baseline and the quadrant is needed for exact location. It doesn’t mean the street name is unknown, and landmarks alone wouldn’t determine the block in this system.
