How Columbia Neighborhood Watch Blocks are organized

CNW is organized by ‘basic’ block units of homes who watch out for each other, and, because they are aware of their neighbor’s comings and goings, which cars and people belong, etc., can quickly spot unusual or suspicious behavior.  In the past 15 to 20 houses was the recommended maximum size for a block unit, but blocks in the 25 to 35 house range can work, although at this size folks are starting to trade off everyone knowing everyone else’s living patterns and vehicles for connectedness over a larger area and convenience of administration.  Blocks longer than about 20 houses usually share a common feature:  a long street with no cross streets, other than small connected courts.  “Suspicious activity” in vehicular or pedestrian form will generally be seen by many of the houses in such a block, and should be of immediate observational interest to those members of the block.
