I did my concept map of cemeteries and how they are effected by urban planning. I choose to compare the Paris Catacombs and the San Francisco cemeteries . First i looked at the where it was happening because the geography of a specific place is very important in understanding why certain choices are made. Also history of a place plays a large apart in it as well. for example both Paris and California created these large burial sites in part by the influence of illness/ hard times.  But also this is due to poor urban planning reactions to growing cities. Paris experienced rapid growth with is proximity to ports and growing population. California was caught in the swell of the gold boom, for a long time there were only one or two cemeteries available in the area and if you died you would be going  to it as well
