Debate is going strong on the Westfield Mall expansion. It is inevitable as time changes that upgrades will be needed. If Westfield does not change their ways, the future could hold an abandoned space that will call for change anyway.
What I see missing from all the newspaper articles and what I have read so far about from the critics are mitigations for non-motorized transit. The LA River Plan calls for a Fashion Square Park and a bicycle/recreational trails.
Westfield and the residents should also consider LA River mitigations in addition to roadway/traffic ones.
