I noticed today that a new sign was put up in serra mesa reading Welcome to Mission Village. Has there been a name change? Was this decided at the planning committee?

I'm not sure in what year you wrote your post but...I just moved to the Mission Village area and have been a long time resident of Serra Mesa.  I always thought Serra Mesa ended at Gramercy and Ruffin where Mission Village began.  There is a sign that says "Welcome to Mission Village" on the incoming side of Mission Village from the stadium that has been there as long as I can remember (15+ years)
