In my area (Seattle metro), I’ve noticed the majority of new subdivisions in the suburbs are still being built disconnected. Even in new construction, there are few (if any) pedestrian/bike cut-throughs, making access very circuitous if you were to try to walk to a school, bus stop, or neighboring subdivision.
This is noticeably worse in unincorporated areas than in cities, and I have noticed some cities are a lot better at fostering connectivity than others. That said, I think there should be way more connections in general — EVERY cul-de-sac, 90-degree turn, or T intersection should have a pedestrian path continuing straight through to form a grid.
Why are some places better than others? What can be done to make sure ALL places are held to the same standard?
