I like the idea of using the 12 Community Districts because those are official districts of the city and do not have to be named and defined and explained and defended I suggest adding a CDs neighborhood column to the tables and beginning to identify which is the CD for each entry When enough are identified then split out separate list articles Perhaps the CD s having most Landmarks get separate articles and smaller CDs are left combined into one list article Anyhow i would identify the CDs on this list article and see how many are in each before deciding on split to implement That would be a lot of work to do but i don t see the need to rush to split either
