Austinite here. East of I35 is commonly known as the "wrong side of the tracks". If Austin is wiring up for business and residential focus, they'll do west, some limited up north, downtown, and down Congress Avenue & First Avenue. They might extend to the west of MoPac (Loop 1, follows the old Missouri-Pacific line) but I'm not sure that the neighborhoods there are officially part of Austin or incorporated as a small suburb community.
