My personal kit is a lot smaller, but with urban hikes I'm usually within a couple hundred yards of the road and taking it easy. I'm not guiding scouts.

*Pack - Small field (shoulder) bag. About ~6.5L capacity.
*Walking stick.
*Navigation kit - flashlight, baseplate compass, and map. No downsizing from the rural hikes kit.
*First aid - Sawyer extractor in the summer, nothing in cooler weather.
*Emergency - Storm whistle, full size lock-knife, lighter, flint, and tinder.
*Water bottle
*Depending on weather, location, and reason- Poncho, field guides with measuring tape and magnifying glass, notebook, sweater/jacket, and space blanket.
