If a location is given as the 850 block with no landmark or quadrant, what is the recommended locator approach?

• A. Use the block number as the sole locator
• B. Verify the block number before referencing any landmark
• C. Request a landmark for verification and use the block number as backup
• D. Wait for confirmation

Answer: (C)

Locating a place using the Major Street Hundred Blocks system relies on anchoring to a known landmark to fix the exact spot, because block numbers alone can be ambiguous without cross streets or quadrant information. When a location is given as the 850 block with no landmark, the best approach is to ask for a landmark to verify the exact spot and then use the block number as a backup reference. This helps prevent confusion since multiple blocks can share similar numbers on different streets, and it lets responders confirm the right location quickly. Relying only on the block number can lead to misidentification, and waiting for confirmation can slow the response. So, verify with a landmark first and use the block number as a backup.
