I spent 2 months working around Chicago, and if you aren't doing 20 over you are a hazard to traffic, so I'm on the upper end of the speed thing. The area in question is a country 2 lane, but they built a few subdivisions there. It's obviously very very upscale, bordering on gated community, so for them they get the speed limit sign that has the police light on it, 15 mph slower than the rest of the street (the rest is quite curvy even), 6 foot wide sidewalks, and nice turn lanes so they don't have to get rear ended. Meanwhile a very very busy street a couple streets down has no sidewalks, painted on bike lanes because there's a ton of lower class pedestrians, higher speed limit, and no turn lanes. I haven't done any trees there yet, but if i do I'm honestly going to tack on an extra 50 percent just because you must be an ass to live there.
