One obvious example that comes to mind is Wiki Loves Monuments. Others are the Wikipedia Challenge in Kiswahili and Setswana, and edit-a-thons, such as this year's fashion edit-a-thon put together by Wikimedia Sverige.
What am I missing from this list?
I don't know, maaaaaaaany things. 1) I'm confused: first you ask about community initiatives then you list activities by chapters and the like. "Community initiative" makes me think of edit drives, custom tools and scripts, processes, guidelines, configurations. 2) Are you interested in last year or all our history? 3) Is it really impossible to look for the impact on the statistics (assuming you're speaking of eiting activity) and then ask what caused the impact? How much big but indetected/undetectable impact is there? (There must be contrasting forces for that.) Are you interested in impact that can't be even seen in statistics?
