1) While, I can't personally speak (much) to walking around Dallas, I can speak quite a bit to walking around Austin, Texas. Walking around on a day that is 110º is doable, because the humidity is rarely ever that high, when the temp is.

2) Shade trees lower the temperature for the air under them, by as much as ten degrees.

I'm not arguing there shouldn't be trees,at at least where I'm at in DFW there's tons of them, I'm just arguing that dropping the temp from 110F to 100F still doesn't change the fact walking around in even 100F at decently high humidity will render most people a sweaty mess in a block. We had weeks where the heat index was around 120F this summer.

Even just sitting around outside in a shady backyard with lots of vegetation, a pool, and umbrellas we were still sweating profusely this last summer.
