Dear Jennifer Kim
I understand your retreat into pandering given the difficulties you're currently facing, and I even sympathize a bit, but let's be clear: big retail and employment destinations do NOT NOT NOT NOT belong on frontage roads.
This talking point works well with people who drive everywhere - like most folks in Allandale. It doesn't work so well with people who actually have some experience with alternate modes of transportation, like yours truly. I used to occasionally ride the bus in the morning and get off at the stop on one side of 183 between Oak Knoll and Duval and have to go to exactly the other side - and the presence of frontage roads (destroyed an old road which used to cross) made a 2-minute walk into a 10-minute bike ride (30-minute walk). No wonder nobody else does it.
