Here's a map I threw together of Haven City circa Jak II. I didn't make the image myself, but I did add the colorful dots and information on the right side, as well as label the city sectors. And yes I added a few things from my OC's story like her house and place of work, it will come in handy in the future.
I actually forgot to pinpoint Geronimo's childhood home [which would be in the slums near the water slums], and I guess the schools of Haven City for that matter [since they aren't mentioned in the games but obviously are needed for a town to be
a town, I will find a place for them; especially since Geronimo goes to school in her story].
For my own benefit I'm going to list the names of the schools [for when I have time to go back and edit the above map] and their locations. For simplicity's sake I'm going to say Haven City doesn't have any colleges; if you want to go to community or a private college, you need to go to Kras or elsewhere. So, the Haven City School District: Yakow Daycare for toddlers, located in the West Bazaar; the pre-school and kindergarten are one building which is located in the northern gardens [the school's "mascot" is the precursor orb]; the elementary school has adopted the crocadog for its mascot and teaches 1st through 5th grade, located near Mar Memorial Stadium in the main city district; the middle school has grades 6th through 8th where their mascot is the hip hog and it's located near the border between the industrial section and the slums; there is also a strict private school that covers grades K-12 [that's age 5 to age 18] where they have the metal head as a mascot, is rather expensive, and is located in the main city district near the palace support towers access; and finally the public high school has grades 9-12 [age 14 to age 18] where the barbaric stereotype of the lurker is their mascot, located in the main city district nearer the palace, in an attempt to force patriotism for Haven City down students' throats.
