Great neighbourhoods for trick-or-treating also tend to be great neighborhoods for families everyday:
Tree-lined streets designed for walkers more than speeding cars.
Enough density and community completeness, to activate what I call “the power of nearness” – everything you need, nearby.
Good visual surveillance through doors and stoops, windows (and I don’t mean windows in garages), porches and “eyes on the street.”
Connected, legible streets that let you “read” the neighbourhood easily -grids tend to be good for this, but other patterns work too.
All of these are great for trick-or-treating, and equally great for walkable, healthy, economically resilient communities year-round.
