Disconnected subdivisions — how to prevent?? : urbanplanning

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?
