It'd be nice to know what traffic mitigation was required for these developments, beyond just paying impact fees.

For Summit Park, 126 homes is enough to warrant a traffic signal at 236th & Kent-Kangley, but a roundabout would provide more capacity with less delay.  If a signal is constructed, it needs to be coordinated with the ones at 169 and 228th.

For "Lake Wilderness", the traffic signal at 169 and 264th should be converted to flashing yellow arrow left-turn phases on all approaches.

For "Four Corners", the intersection of 271st and Kent-Kangley should be converted to a roundabout (which should've been required to be built by Fred Meyer).

All this residential development will push the City's population over 25,000, which will then make the City responsible for maintaining almost everything on 169 and 516 except the pavement.  I hope the City is budgeting for this eventuality.
